Ninja World: I Have a Life Simulator

[Seven days later, you successfully enroll in the Ninja Academy and join the same class as the main characters from the original series!]

[To earn more money legitimately, you apply for early graduation after a month, having already achieved the strength of a Genin.]

[Konoha arranges for a Genin, Hyūga Jinkū, to battle you!]

[In three minutes, you are defeated and become the laughingstock of the school!]

[Five months later, you learn the Great Fireball Technique!]

[Nine months later, your chakra reserves increase by 30%!]

[Eleven months later, you learn the Shadow Clone Technique!]

[The Uchiha massacre begins, and you die!]

...

Seeing the outcome of the new life simulation, Akira sighed inwardly.

So, is the Uchiha massacre truly an insurmountable obstacle for me?

However, this life simulation did yield some significant rewards—an additional 30% increase in chakra reserves from where I started.

That's a pretty good improvement!

Additionally, I mastered both the Great Fireball Technique and the Shadow Clone Technique!

The Great Fireball Technique is almost a must-learn for members of the Uchiha clan.

As for the Shadow Clone Technique, while the Multi-Shadow Clone Technique is an A-rank forbidden jutsu, the basic Shadow Clone Technique is only B-rank in difficulty.

Since my Sharingan did not evolve, after considering the chakra and ninjutsu options, I chose to acquire the ninjutsu!

A sudden wave of understanding washed over Akira, and he found that he had successfully mastered both the Shadow Clone Technique and the Great Fireball Technique!

However, given my current chakra reserves, the chakra cost of these two techniques is still too high!

The next morning, Akira's grandfather was once again waiting eagerly in the courtyard, curious about Akira's progress.

Without wasting any words, Akira formed the necessary hand seals and immediately performed the Great Fireball Technique.

A massive fireball, about two meters in diameter, illuminated the excited and joyful expression on his grandfather's face!

Though it was indeed strange that his grandson kept asking for money...

But the fact that he had truly mastered the Great Fireball Technique overnight made his grandfather extremely pleased!

Afterward, he left the house humming a tune, clearly eager to brag about it again!

By noon, Sasuke had come over, clearly having heard that Akira had mastered the Great Fireball Technique, and challenged him to a duel.

Two huge fireballs were released from Sasuke's and Akira's mouths, and it seemed that Akira's fireball was slightly larger.

This made Sasuke a little dissatisfied, and he quickly left, presumably to train harder, viewing Akira as a rival!

Watching Sasuke come and go in a hurry, Akira smiled and shook his head, thinking to himself, "Ah, the innocence of a child!"

Reflecting on possible ways to grow stronger more quickly, Akira decided to try a different approach the next day.

When the next simulation began:

[Six days later, you decline enrollment in the Ninja Academy, choosing instead to train on your own!]

[Seven months later, your chakra reserves increase by 30%!]

[Eleven months later, realizing that the Uchiha massacre is approaching, you gather enough supplies and hide in a tree hollow in a training ground forest within Konoha.]

[One year later, having exhausted your supplies, you sneak out at night using a Shadow Clone to search for food.]

[One year and two months later, you are killed by a masked ninja!]

...

This time, Akira decided to hide and see if he could survive the Uchiha massacre.

But the final result showed that although he managed to avoid the massacre, he was still trapped in the lion's den that was Konoha.

He only managed to survive for three extra months.

This time, the focus was primarily on chakra training, and thanks to the extra three months of survival, Akira chose to increase his chakra reserves!

With this choice, Akira felt a significant increase in his chakra reserves!

In terms of sheer volume, it felt like his chakra had doubled.

It seems that the Shadow Clone technique played a crucial role!

Training simultaneously with his real body and Shadow Clones had an amplifying effect!

It seems that simply hiding away isn't an option either...

After mulling over his strategy and with only a little over 1,000 ryō remaining, Akira decided to try another simulation the next day.

This time, he opted for a different approach:

[Five days later, you successfully enroll!]

[Five months later, you regularly train with two Shadow Clones assisting you each day. Your chakra grows rapidly, and you learn the Phoenix Fire Jutsu!]

[Nine months later, you apply for early graduation, and Konoha arranges for you to fight Genin Hyūga Jinkū as your opponent!]

[After a ten-minute intense battle, you and Hyūga Jinkū both suffer severe injuries, ending the fight in a draw. You successfully advance to Konoha Genin!]

[Graduating at the age of six, your fame rivals that of Kakashi Hatake, and you become a well-known genius in Konoha!]

[Ten months later, you finally receive a mission to leave the village and take it, leaving Konoha!]

[Eleven months later, news of the Uchiha massacre shakes the ninja world!]

[Fifteen months later, having not returned to the village, Konoha classifies you as a B-rank rogue ninja!]

[Three years later, while wandering in the wild, you are ambushed by an Anbu from Kirigakure who covets your Sharingan, and you are killed!]

...

Phew! Seeing this life simulation, Akira let out a long sigh.

Though he still met an early death at the age of nine, at least he survived for three more years!

During these three years of training, the most significant gain was not new ninjutsu but the substantial increase in chakra reserves!

This time, Akira again chose to increase his chakra reserves!

Boom!

With Akira's choice, a massive surge of chakra erupted from his body!

His chakra reserves instantly tripled!

For a moment, Akira found it difficult to control, and he could almost see the chakra overflowing from his body!

"Surviving for three years made a big difference! My chakra has increased significantly!" Akira thought, overjoyed at the changes in his chakra.

Bang! The door to his room was suddenly slammed open, and his grandfather rushed in!

Seeing the surge of chakra around Akira, his grandfather was stunned: "My dear grandson, what... what's going on?"

"I don't know either. My chakra just suddenly increased!" Akira replied with a shrug, pretending to be just as clueless.

After carefully checking his body, his grandfather confirmed that while Akira's chakra reserves had indeed increased dramatically, there were no adverse effects.

This allowed his grandfather to breathe a sigh of relief.

However, as he left, he couldn't help but wonder.

First, Akira awakened his Sharingan by simply falling.

Then, after sleeping, he suddenly mastered the Clone Technique, Transformation Technique, and even the Great Fireball Technique!

And now, this morning, his chakra reserves had inexplicably skyrocketed?

What's going on? Could my grandson really be the reincarnation of the Sage of Six Paths?

His growth rate is terrifying!

Over the next few days, Akira spent time adjusting to the sudden surge in his chakra, which took several days to fully control.

During this time, Akira refrained from asking his grandfather for more money.

After all, spending 3,000 ryō in just three days as a six-year-old was hard to justify!

So, he decided to wait until after graduating from the Ninja Academy.

In the simulation, he was able to draw against a Genin and graduate.

With three additional years of chakra training, graduating this time should be even easier.

Once he becomes a full-fledged ninja, he'll be able to take on missions and earn money!

As it happens, tomorrow is the day he's set to start at the Ninja Academy...
