I developed the devil fruit seal in Naruto

Chapter 1: Azure Dragon Curse
A dark basement.

The air was damp, musty, and filled with an uncomfortable odor.

In the aisles on both sides, there are rows of empty petri dishes, and next to the dishes there are some white anthropomorphic objects.

In the innermost room of the basement, high-wattage incandescent lamps make it as bright as day.

A young man wearing a white coat and black-framed glasses, who looked to be no more than sixteen or seventeen years old, was standing in front of the operating table, nervously operating something.

Cold sweat broke out on his forehead and nose. In his left hand he held a sticky substance and in his right hand he held a bottle of liquid that looked like blood.

"I must succeed. I must succeed this time. If I fail again, I'm really going to bang my head against the wall!"

The boy named Uchiha Kyon said to himself:

"God damn it, I was just enjoying a romantic action movie at home, why did you suddenly send me to this dangerous ninja world, and to the Uchiha clan, which is particularly hated by everyone?"

"Five years have passed. Five full years have passed. Do you know how nervous I have been during these five years?"

Even though the combat power of the later Naruto world exceeds that of the One Piece world, the power of the Devil Fruit cannot be underestimated for ninjas who are not at the Six Paths level.

If Uchiha Kyon could eat a devil fruit, he would instantly have the ability to protect himself, and at least he wouldn't have to worry as much as before.

As for why not choose the Sun God Nika Fruit, which is stronger than the Blue Dragon Fruit.

then.

At the critical moment, the system awakened.

Even when he was sleeping at night, he felt there was a pair of malicious eyes behind him.

That’s not all. What worries Uchiha Kyon the most is the precarious status of the Uchiha clan, which is becoming increasingly unpopular in Konoha Village.

It’s not that every devil fruit is so expensive, but what he wants to buy is the Fish-Fish Fruit, the Mythical Beast, the Blue Dragon Form!
This is a god-level fruit, so of course its price is much higher than other fruits.

Wherever he went, he felt like he was being watched.

A system mall appeared in front of him, and he could use real money to buy things in the mall.

Fortunately.

The things in the mall also gave Uchiha Qiong hope.

Uchiha Kyon tried his best to persuade his sister to take out the inheritance left by their parents, mortgaged their own house, and went out to catch bounty criminals regardless of danger to exchange them for money on the black market, and finally he collected 90 million taels.

He remembered that when he first traveled through time, he was just an eleven-year-old kid. His parents died in the Third Ninja World War, leaving only an older sister who was three years older than him at home.

That is a devil fruit, a devil fruit from the world of pirates!

Firstly, he really has no extra money, and secondly, the Nika Fruit needs to be awakened to unleash its true power, and it also requires kryptonian. Uchiha Kyon still wants to live a few more years.

Thinking back on the past five years, Uchiha Sora's eyes were filled with tears.

Although the clan leader's children had entered the Anbu at the age of eleven, Uchiha Kyon did not have such good talent and conditions.

The ninja world is too dangerous, I want to go back to Earth!
Uchiha Qiong gasped for breath, cold sweat running down his body, but he could only despairingly accept the reality that he had traveled through time.

Countless nights, he woke up from his sleep with a start, dreaming that Danzo was digging out his eyes, that Uchiha Itachi was chopping off his head, and that Orochimaru was dissecting his corpse.

What's more, in the eyes of his modern soul, eleven years old is the age for playing in the mud and licking lollipops, but forcing them to learn all kinds of assassination and attack techniques is simply child abuse.

The Qinglong Fruit is different.

Not only does it have the ability to control various natural disasters such as wind, thunder, and fire, but it can also allow people to gain unimaginable vitality, defense, and recovery. This is of great significance to the Uchiha, whose bodies will suffer from kidney deficiency if they overuse their eyes.

Uchiha Kyon was very much looking forward to it. After eating the mythical beast Blue Dragon Fruit, when he could open the Sharingan or even the Mangekyō Sharingan in the future, would he not have to endure the side effects on his body?

With great excitement, he paid 90 million taels to the system.

However, God played a huge joke on him again.

The devil fruit bought from the system mall cannot be eaten directly, otherwise you will die immediately!

Hold! ! !
Uchiha Kyon angrily opened his magatama and almost smashed the mythical beast Qinglong fruit in his hand.

I spent 90 million and you told me I can't eat it. Are you kidding me?
Uchiha Qiong's eyes turned bloodshot, and the system gave a prompt that although the devil fruit could not be eaten directly due to the different compatibility of the two worlds, it could be used for research.

Research?

Uchiha Kyon calmed down and immediately thought of Vegapunk, who had created an artificial Blue Dragon Fruit.

But this is the world of Naruto, where can we find Vegapunk?

The most powerful scientist in the Naruto world should be Orochimaru.

If I go find Orochimaru...

Just thinking about that scene made Uchiha Kyon shudder.

Given Orochimaru's greed and evil, he would probably end up being sliced ​​into a slice in the laboratory before his research results come out.

After racking his brains, Uchiha Kyon finally made a decision that went against his ancestors.

Damn, no one can be trusted, so I'll just do it myself. After all, I received nine years of compulsory education in my previous life, and my major in college happened to be biology.

Uchiha Qiong was determined that his 90 million taels must not be wasted, even if he threw them into the water, they would make a sound!
that's it.

Five years ago, no one knew that the Uchiha clan, the most powerful clan in the ninja world and the Konoha Guard, had a new anomaly who did not develop the Sharingan, did not practice ninjutsu, and was devoted to academic research.

This is probably the first time in the history of the Uchiha clan to develop a technology tree. If Senile Spots were still alive, I wonder what he would think when he saw it.

Hard work pays off.

With the foundation from his previous life, Uchiha Kyon could easily understand knowledge such as cell transplantation and bloodline factors.

Even more luckily, he also accidentally discovered a secret laboratory left behind by Orochimaru before he defected from Konoha.

In the laboratory, there were a lot of information that Orochimaru had not had time to take away or destroy, most of which were related to Hashirama's cells, as well as curse-sealing techniques, reincarnation techniques and other miscellaneous information.

Uchiha Kyon accepted everything that came his way and read and learned voraciously.

He almost went crazy with his studies, constantly mixing the devil fruit with various techniques for research.

Finally, he found a way to extract the power contained in the devil fruit, which was to integrate it into the curse seal and then inject the curse seal into the body.

Uchiha Kyon named this technique the Devil Fruit Seal. Each fruit corresponds to a seal, and the one he wants to fuse at this moment is the Blue Dragon Seal!
The fusion of the curse seal is not that easy.

Even though he knew the principles and methods, Uchiha Kyon still kept failing.

The more times he failed, the more anxious and crazy he became, and he was almost falling into a state of insanity.

The Azure Dragon Fruit, the mythical beast that he had spent ninety million taels on, was almost consumed bit by bit during the failed experiment.

Right now, Uchiha Kyon has only the last few copies in his hands.

If he continues to fail, he will really have a mental breakdown and bang his head against the wall to see if God will let him travel through time again.

"Huh~"

Uchiha Qiong took a deep breath, kept himself absolutely calm, slowly brought the two things in his left and right hands closer, mixed them together, and stirred them gently.

The sweat on his forehead dripped down his cheeks onto the table.

My heart almost rose to my throat.

a certain moment.

A silly smile appeared on Uchiha Qiong's wooden face, and then the silly smile turned into the classic Uchiha laugh.

“Hahahaha! Hahahaha!! Hahahahahaha!!!”

“I succeeded, I finally succeeded!”

"Blue Dragon Curse Seal, let me feel what it feels like to be a strong man!"
