Harry Potter World with a Simulation Choice System Chapter 1-5 (Patreon)

Disclaimer: all the character’s in the story that have any sexual interaction are 18 years or older. All the forced situations that appear are all just an act by the protagonist to fool the enemies and gain benefits.

Chapter 1: transmigration into wizard world

An old assassin was sought out by his own son and killed him to get the power of the head of the international assassin’s organization in to his hands.

“Old man your skills are becoming rusty these days and you were killed using this simple trick.

Are you really the greatest assassin in the world?

From now on I am the greatest assassin in the world.”

“Hahahaha”

But suddenly the old man started to laugh loudly.

“Son, you should know in your heart that did I really tried to avoid being killed by you.

It is just that I am bored by this world.

Well there are beauties but I am not young any more.

So I wanted to leave this world peacefully.

In order to let you inherit the throne of my assassin’s organization, I pulled some strings to make you come here and kill me.

You will gain prestige and I will rest in peace.

Hahahaha………..

Son before I go I will give you a final advice.

‘Don’t fall into this kind of silly traps and try to kill someone you cannot.’

‘The assassin is called assassin, not because he can kill but kill the person without the knowledge of the other party by any means.’

Ghouf, Ghouf (Sever coughing with blood in the mouth)

Well my times are up and it is a good last game.

Good bye my son,

Also don’t die early and disturb me on the other side.

Hahaha……. (Laugh and silence)”

The old assassin died sitting majestically on the thrown leaving his son standing like a clown in the silent hall.

“F*** that old man,

He even played with me before his death.

Sigh”

…………………..

“What am I not dead?”

“Why are my hands so small?”

“Wait who are these people?”

“Ah my head hurts…….are these memories……”

“So that is how it is.”

“I have transmigrated.”

“No it seems more like a rebirth.”

“I am an assassin in my previous life and now I am in another world that is similar to that of the previous world.

More like a novel world.

This seems to that magic novel called the harry potter.

Ah yes I have even watched those movies.

Well I am not that much of a fan of this bit that magic thing is interesting.

Also there are some good beauties here in the story plot.

There are some stupid people along with the protagonist.

There are so many things to play here hahahahha.”

At that moment his memories slowly sorted out.

He seems to be from an ancient family called Dekciw.

(The family name is a puzzle if you can find the answer to it)

Vicky’s parents are not complete humans but are half humans.

His father has the bloodline of an incubus while his mother, she is the descendent of the Greek goddess of love Aphrodite.

Because of the varying bloodlines their families are being hunted from a long time.

They accidentally met during the time they are being hunted and escaped.

Then they took refuge with Mrs. Zabini that is a friend of his father and mother.

Mrs. Zabini has the blood line of a succubus.

She hides it so well that no one knows about that.

Instead she became the wizard’s wife for 7 men accumulating great wealth.

His father and mother had their faces recognized by some dark hunters that specifically needed their blood for some sacrifices.

So they cannot stay out for long.

Fortunately they hid the fact that they had a son very secretly.

So their son is safe.

Their only friend is Mrs. Zabini so they came to her to ask her to take care of Vicky.

They did not have long to live.

Previously when those hunters appeared Vicky’s father saved the life of Mrs. Zabini.

Also he helped her hide her identity.

So she gladly accepted to take care of Vicky for them.

She can vaguely feel that they are at the end of the flight and might not be able to see them again.

Vicky is only 3 years old when he was handed over to Mrs. Zabini.

They also gave her the vault key that has all the accumulated wealth of their families combined.

That is the last memory of his parents.

………

After that he grows up along with Blaise Zabini.

Mrs. Zabini really took good care of Vicky and never.

Also Vicky because of his bloodline is the cutest kid there can be.

Blaise cannot hate Vicky because of his strange charm acting on all the people around making them friendly towards Vicky.

This is his bloodline power.

His childhood is very happy for a child.

On his 5th birthday something unexpected happened

When he is playing outside he accidentally fell down from a swing.

After that his current memory of the old assassin appeared in his mind.

With that the personality of Vicky also changed completely.

Right when he is thinking of those memories he heard a strange sound in his mind.

‘Tring’ ‘Tring’

“Simulation Choice System is activated.”

System: host don’t worry even though you are weak, I will help you become greatest wizard in this world.

Vicky: I am not weak, I am only 5 year old here you know

System: host don’t worry the there are various choices, simulations and quests to get the rewards and these rewards can make you the greatest wizard in the world.

Vicky: did you listen what I just said just now

System: there is also the plot of the harry potter story that host has to take care of, which can give you better rewards.

There are also achievements rewards and the story beyond the plot of the harry potter story.

Vicky: stop for a moment first.

I will ask you will explain slowly.

Don’t be too talkative.

Now tell me what your name is.

System: host I don’t have a name by default I was called simulation choice system.

You can give me a name host…..

Chapter 2: Simulation choice system

System: host I don’t have a name by default I was called simulation choice system.

You can give me a name host.

……….

Vicky thought for a moment and said.

Vicky: well I will call you system since you are a system.

Now tell me what your main functions are.

System:

Host the main functions of the system are

Simulation

Choice giving and

Quests

The system can let you see your status panel.

Vicky: okay continue to explain.

Simulation can let you simulate the future under set goals from the host.

Simulating requires host to spend money.

Ordinary money is not usable.

Only wizarding world money can be used.

The amount of time that can be simulated is proportional to the amount of money that player uses for simulation.

One bronze Knut can simulate for a day.

1 silver sickle can simulate for 4 weeks and

1 gold galleon can simulate for 70 weeks.

The simulation results give the host some options to choose from to gain the things that are acquired by the host during the simulation.

Nothing physical can be taken out of the simulation.

The results usually contain memories, knowledge, techniques and important things….

These results are not free and they are needed to be purchased with corresponding amount of money.

…………..

Choices are given by the system at specified situations.

Based on the choice that host take and complete choice, host will be given the corresponding rewards.

………….

Quests are given to the host based on the situations or request from other people.

Based on the performance there is a chance of triggering some hidden details to obtain through the quests.

The quests have both rewards and penalties.

So be careful before accepting the quests.

…………..

Vicky understood the functions of the system clearly then thought of the situations that would happen in the future.

Then there is a big smile on the face of Vicky because the future is very bright.

But Vicky was sure of one thing here.

The things happen in this world might be same as that of in the harry potter novel.

But this is a real world and the things that are mentioned might have some changes because of the vision of the writer and partiality towards a side of a nation.

There are many things that are not mentioned in the story which are loop holes that Vicky did not understand.

Even though he was not interested in the story of harry potter, the setting of the world is nice and Vicky paid attention to it in his previous life as an old assassin as a pass time.

Since he got a chance to come to this world he will see the end of all the loop holes that he thought off in his past life.

Also there are so many beauties that he would not mind taking them all.

Whatever other people might call him it doesn’t matter as he has decided to not to let these girls fall into the hands of men that are like shit.

While he is thinking Blaise appeared trying to help Vicky stand up.

He just saw that Vicky fell on his head so he went to call the servant and his mother to help Vicky.

Vicky dusted off his dress and looked at the lady in magenta dress.

That is a long skirt she is wearing and looked like a goddess.

Mrs. Zabini is as beautiful as they said.

It is no wonder that she was able to marry 7 men and none alive.

Just looking at her would make the men loose themselves in their imagination.

“Vicky, are you alright…”

Zabini asked with the voice that can pull the strings of a man’s heart.

Vicky can feel all of this but his body and mind seems to be immune to all kinds of charm.

“I am fine aunty.

I just fell off the swing.”

Vicky said and started to dust off his new dress.

Mrs. Zabini helped him dust off.

Her touch is soft and she is graceful.

The servant was dazed looking at the scene.

Because of the blood line traits both of them are extremely beautiful.

On the other hand Blaise seems to have inherited the appearance from his father.

He is immune to the charm of his mother but he did not possess a charm of his own.

Well it is a sad thing but who can say what.

After they cleaned off Mrs. Zabini looked at Vicky all over to see if there is any problem.

There is small bump on his head because of the fall.

Other than that there is no other problem.

So they went inside to play some other thing.

Vicky cannot run off to do things right now instead he has to plan the things to happen slowly.

For now he wanted to understand the situations of the world.

Also he seems to have some enemies that killed his parents.

Or

His parents are alive in some other place.

Then the next thing is related to understanding the magic stuff.

He doesn’t know anything as there is no magic back on earth.

To be more precise there should be magic back on earth but some people forcible severed the source of magic thinking that they did greater good for the world.

Anyone and everyone that tried to find the sources of magic were madly hunted and killed back on earth.

Well that was gone.

The current world seems to be going in the same direction.

The magic is slowly fading as the number of magicians is reducing.

The modern world of normal humans is moving forward at a great speed.

In a few years there might not be any magicians any more.

Vicky wanted to find their secret and put everything out for the real world to see.

He doesn’t want to close off the borders of this magic world and the muggle world.

The more a thing is the less previous it becomes………….

Chapter 3: simulating for the first time

He doesn’t want to close off the borders of this magic world and the muggle world.

The more a thing is the less previous it becomes.

If magicians became rare then there will be a day they will be hunted like dogs with no place to hide.

So Vicky wanted to change this.

He don’t know if his parents are alive or not but he wanted to save them if they are alive and avenge them if they are dead.

But first he has to think of a way to simulate.

For his birthday he specifically asked Mrs. Zabini for some pocket money.

There is a wide collection of books in the library from the 7 husbands of Mrs. Zabini.

Vicky has the chance to read them all.

Well the books related to the dark arts were kept in a different place by her.

So, all the books here are normal study books that can give Vicky some good amount of knowledge.

But he is not idle enough to read all these books and waste a lot of time.

He wanted to use the simulation to gain all the knowledge in those books.

His study process would start with history and some of the important facts then.

Unfortunately he did not have that big amount of gold gallons.

His entire funds amount to only 5 gold galleon.

But he cannot hope that the 5 gold galleons can let him read the books for 350 weeks.

Based on the information from the system even buying the memories from the system would need him to spend money.

The memories that he want to buy can cost based on the value of the memory based on the system.

This means that he can only use 1 galleon for simulation while saving 4 galleons for buying the memories.

Since the funds are tight Vicky wanted to change his targets and priorities.

He changed his targets to basics, history, and some knowledge about this world’s muggles development.

While he made the decision it was already after noon and Mrs. Zabini asked them to go to sleep with the help of some nanny.

After thinking of that Vicky pretended to sleep and started his simulation spending 1 gold galleon.

Based on the count it should be around 493 days or about 70 weeks which should be around 16 months.

Immediately the simulation panel started.

It went on by days where Vicky would go to library every day to study.

Other than that his daily routine has some exercise plan studying his body potential, studying from the teachers arranged for him and Blaise.

These courses contain, math, history, eloquent, etiquette….

Well Vicky doesn’t need them as he already learnt them all in his previous assassin life for various reasons.

Right now he is only 5 years old and cannot show his maturity.

It will cause him problems.

In the simulation he learnt all the basics in the first month then he moved on to history that took him around 5 months.

After that he learnt the basics of magic and other important things related to this world along with world history.

This took him longer than expected which is around 8 months.

There are around 2 and half months left for him to learn.

Vicky used that time to learn about the political details of the current muggle world and magic world.

The more he learnt the more he became interested in the simulation.

From the simulation details it said that Vicky calculated that the current muggle world technology is around 15 years slower than that of the human technology back on earth at that time.

After the simulation he looked at the options.

“Tring

Please choose the following options.

Since it is the first simulation player was given a discount of 50 percent.

Option 1: Basics of the wizarding world (7 silver shillings)

Option 2: basics mathematics (1 silver shilling)

Option 3: wizard world history (13 silver shillings)

Option 4: current political knowledge of muggle world (16 silver shillings)

Option 5: memories of assessment of the body potential by the host (9 silver shillings)

(There are more options below and I don’t want to list them all)

………….

After Vicky looked at the list and selected the things that he wanted which has reached around 3 gold galleons and 15 silver shillings.

The face of Vicky darkened because this means he will only be left with 2 silver shillings.

Even though he knows this he cannot do anything about it.

So he just bought the entire thing resulting in his brain flooded with all the new information.

He has a head ache.

It was so strong that he fainted on the spot.

Even in his sleep he has this dream of all the things mixed in forming a nightmare.

Finally by the time it was evening Vicky woke up with all the memories sorted out.

He sighed by the amazing amount of information in his brain.

With the basics done Vicky moved on with his birthday party in the evening.

Even though he was being raised by Mrs. Zabini many people were called for his birthday party.

For those people Vicky was introduced as the son of her brother.

Many kids from the rich families arrived here which included Draco, pansy, Daphne and her sister Astoria….

Vicky was very happy to play with them in that evening.

“It is too much tiring to act like a kid.

Fortunately I am good at acting if not I would have showed many flaws.

Sigh…

A dignified assassin king like me has reduced to use my acting skills to act like a kid in front of these morons.

This should be my punishment for not taking cheating that countries head with his wife and daughter…

Sigh...”

As Vicky thought there are some adults but all of them are mothers of the children that came to his birthday party.

All of them are beauties in their own right.

Unfortunately they married to some snob………

Chapter 4: isolated world

All of them are beauties in their own right.

Unfortunately they married to some snob nosed morons.

“Don’t worry beauties when I grow up I will take care of you and your daughters in place of your husband…”

The party is over and Vicky got some good gifts at the end.

Unfortunately they did not give him any money.

All of them are either toys or books or something else…

Vicky can only act happy while he is still sad.

The birthday party is over and the girls have literally stuck to him because of his strange charm.

Those hot mothers were unable to let Vicky go because of his cute appearance.

When they all left Vicky was finally free.

His child body was very much exhausted and slept directly.

Vicky has some idea on the plot.

He has to wait till 1990 before investing in some companies in the wizarding world.

As for the muggle world Vicky has to think deeply to solve some things first.

Then he can invest in the companies and think of a way to become rich in both the worlds.

Also there is a problem that he solved after coming to this wizard world.

Why do wizards fear to fight muggles?

The answer is simple.

Muggles have number superiority while wizards have limited amount of magic power.

So wizards can only run instead of fighting.

The sheer number of muggles is enough to kill the wizards.

In the modern technology of guns and other things has another big threat to the wizards.

Well wizards can put on the magic shield if they know that the bullet is coming from the front.

But there are snipers that can shoot from a distance of 500 meters which is very long for normal humans to look and perceive.

One cannot hide from the enemy in the dark.

So the wizards have decided to hide.

Well not all wizards want to do that but there is no choice.

In order to make the wizards hide completely some wizards specifically spread rumors that wizards are nasty people that would use humans for their sacrifices.

This made muggles made and completely exterminated the good amount of wizards.

This resulted in wizards have no choice but to hide from muggles.

There seems to be another great wizard that did something to the world to isolate it from magic.

For this reason the amount of magic in the world is reducing day by day to the point that wizards need a wand to cast magic.

Originally wizards did not need a wand to cast magic.

Wands or other magic accessories are only used to amplify the magic.

But now the result is what everyone knows.

Vicky wanted to find this secret and if possible he wants to break that isolation seal to see what real magic feels like.

On the next day Vicky started to do his regular exercise without causing any problems for the growth of the body.

Even though he is an assassin he has studied many ancient scriptures back on earth because of his interest in magic.

That is also the reason why he studied the novel of harry potter.

It is not for the main character that he studied instead he wanted to know how the magical world would look like.

The thing here should be the same as back on earth.

The wizards here have survived by hiding, but the wizards back on earth died with bravery.

Also the scriptures back on earth have many similarities in regards to meditative models in this wizarding world.

Back on earth magic was extinct so those scriptures and spells there are useless.

But here they can still work.

There is one problem that is he has to adjust them a little, to fit for this world through trial and error.

Well the file itself is perfectly alright but the opening directory is wrong.

That is the problem with the spells back on earth and this wizarding world.

Well he has a long time to do that along with studying the entire syllabus of the Wizarding School.

Vicky was sure that he would get a letter and can directly enter Hogwarts School.

What made him the king of assassins back on earth are his planning and preparations.

He wants to follow the same principle here too.

Right now he cannot show his expertise to Mrs. Zabini to create flaws so the dead line he put himself is the age of 9 years old.

Before that he would study normally and accumulate the money using some small tricks.

With the accumulated money he would simulate and buy the memories that he wanted.

This is his plan for the next 4 years.

Many important things would start when he was at the age of 9.

This is the best time for investing in many places to get some huge returns.

For that Vicky is planning.

If Mrs. Zabini lets him go he wants to go around the rich streets of England and Scotland to steal some money and convert it at the Gringotts wizarding bank.

But he cannot do that right now because of the same old restrictions of his age and bla…bla…

Finally his life changed to a different daily routine where he would exercise every day, study at library and ask for books that he wanted from Mrs. Zabini.

His body shows the sign of growth and the muscle is not bulky instead it is more refined.

That is the difference between his exercising process and those body builders.

Even if he stops exercising he would not lose his current muscle.

But if those body builders stop exercising then they would lose their muscles as it will turn back into fat.

Vicky did not stop at that he asked Mrs. Zabini for some throwing knives for practice but he was not permitted being a child.

So he can only use the other way of using wooden sticks or other things for play……….

Chapter 5: simulate again

Vicky did not stop at that he asked Mrs. Zabini for some throwing knives for practice but he was not permitted being a child.

So he can only use the other way of using wooden sticks or other things for play.

………..

Time passed by.

After 3 years Vicky was now 8 years old.

He was able to accumulate few gold galleons after saving up his pocket money.

His birthday party was held again and many rich women along with their sons and daughters appeared in the party.

Some of them are beauties that appear in the harry potter series.

Their appearance has some slight changes which made them really beautiful.

Also some of them appearance are completely different.

The wizards looked really beautiful like noble men and women.

The party is fun as Vicky has the beauty that other envy.

He is showing his handsome side at a young age.

Also he is cute.

His words make the people happy so everything is fun.

This time Vicky received some specifically made dresses and other magical things are gifts.

No one paid money as a gift which disappointed Vicky very much.

In the past 3 years with his continuous exercise that would not break the growth potential of the body he has achieved some good results.

His body is showing signs of getting stronger and his instincts with weapons and things also improved.

During this time he did not have enough money for simulation.

So he has to depend on his own efforts to study and memorize all the information that he possibly can.

But there are simply too many books to learn.

For this point Vicky really admires Hermoine.

She was able to memories so many things with her hard work and passion.

Vicky knows that this should be the time he should start showing his capabilities of a genius.

This way he can suggest to Mrs. Zabini.

While understanding about the things Vicky got the real name of Mrs. Zabini.

It was Yemaya and she has her origins from Africa.

Well it is true as she is a succubus that has her ancestors escaped the disaster earlier on and went to hiding.

(I don’t know the details as I found the name in some article on web.)

(The follow up succubus story is my addition)

For an entire year Vicky has practiced hard and his movements became very smooth.

But he cannot stop the practice till his body stops growing.

The change in the size of the body can change the balance of his movements too.

For now his current body has completely adapted to the movements of all techniques.

During this year Vicky did not simulate.

Instead when he reached 9 years of age that is the year is 1989,

After the birthday party Vicky used the money he has on to simulate for 473 days.

His target of simulation is knowledge on the market changes for the next 473 days.

At the same time Vicky also wanted to know the reaction of Yemaya Zabini towards his actions and thoughts.

“Tring

Please choose the following options.

Option 1: medicinal herbology (1 gold galleon. 2 silver shillings)

Option 2: forging and metallurgy, material knowledge (1 gold galleon. 5 silver shillings)

Option 3: normal daily memory of 473 days (1 gold galleon)

Option 4: memories specified towards the financial detailing and analysis (2 gold galleons)

Option 5: memories of the flaws and corrections during physical exercises (3 silver shillings)

……………”

Vicky calculated and found that all the things that he wanted would cost him 7 gold galleons.

He just barely had the money after playing his cute words a few times to make Yemaya to give him money.

His money was directly put into action and the memories flooded his mind directly knocked him out.

Fortunately he is currently on the bed and this is sleep time.

Vicky used the time to sort out the things and he already knows how much he has in his vaults and how to convince Yemaya to let him move money.

With that his plans starts from tomorrow morning.

On the morning next day Vicky directly went to Yemaya’s room and knocked on the door.

It was early in the morning and she is still in her night dress.

Looking at her appearance even Vicky the old assassin has to blush.

That is how beautiful she is.

But he shook his head to sober up and speak about his purpose of visit.

Vicky wanted Yemaya Zabini to take him to Gringotts bank to check on his bank account.

Immediately Yemaya asked Vicky if he wanted some money.

She is willing to give him.

But Vicky shook his head and pulled her to the study and asked her to put on a special sound restriction that would seal of the sound from the outside.

Well she became curious about Vicky and immediately put out a sound restriction barrier around them.

With the barrier present Vicky told her about a secret.

Naturally he would not carelessly speak out his secrets.

But this time it is different.

In the next year there is a small case where Vicky was captured by some people when they went out to buy things for joining Hogwarts.

At that time Yemaya almost lost her life protecting Vicky.

Vicky has instinctively pulled her to the side in the simulation when the attack happened.

If he did not pull then the curse would have hit her head killing her directly.

Originally it was Vicky that was in that spot.

Yemaya pushed Vicky to save him from the unexpected danger without caring for her life.

Right then Vicky instinctively pulled her hand with all his strength.

All the exercise all this time made it possible for him to pull her just enough to save her life.

This kind of thing cannot be planned.

This is because if Vicky was not strong enough or his instincts were not strong enough or few other factors…………
