Naruto Demon Law

"The prodigal son will never change his money..."

"Asma's nature is not bad, don't worry, Sarutobi-sensei, Feiyan who left home will return to the nest after all."

Looking at the old man in front of him who was sighing long and short, Yu could only comfort him softly.

"Wouldn't the prodigal son be exchanged for gold..."

Hearing the words of the seven or eight-year-old old Yu Hengqiu in front of him, and savoring the wise words carefully, he saw a strange look on the face of the third generation, "I really don't understand where you have so many philosophies..."

If it weren't for the fact that the identity of Yu War Orphan was clearly registered in Konoha, the three generations would almost have thought that the white-haired boy in front of him was occupied by the soul of some old monster to expel his shell.

Not only can he think about problems like an adult, but what he often says can be thought-provoking.

"By the way, do you have something important to ask me?"

After a few brief chats, Sandai regained his seriousness and looked at Yu in front of him.

Except for cultivation, Yu would never take the initiative to look for him in Hokage's office if there was no important matter.

"Well, in the medical class..."

"I developed something like this when I was idle..."

Yu nodded, straight to the point and took out a medical talisman from the pocket of his white coat.

"This is?"

Looking at the white talisman paper that Yu put on the table in front of him, Sandai couldn't help but frowned, he knew that Yu would not give him an ordinary detonating talisman for no reason.

"Look clearly, this is not a detonating talisman..."

"It's a medical talisman specially developed by me..."

Looking at the puzzled expression of the third generation in front of him, Yu simply released a sharp thin thread from his hand, which directly cut the skin on his hand, and blood immediately spilled on the floor.

But soon, Yu directly put a medical talisman on his wound, covered with green medical chakra, and the small wound recovered in a blink of an eye, without leaving a trace.

"Doctor...medical talisman?!"

Seeing the scene in front of him, Sandai suddenly widened his eyes, and his breathing became uncontrollable.

As a Konoha Hokage with outstanding vision, Sandai naturally saw the value contained in this thing at a glance.

"How is the treatment effect?"

Suppressing the excitement in his heart, Sandai looked at Yu with glowing eyes.

"It's not bad...Although it's not as good as the Palm Immortal Technique, the effect is almost the same as that of the Healing Technique."

Looking at the excited third generation in front of him, Yu nodded with a smile on his lips.

"Can it be mass-produced?"

Grabbing the medical talisman in Yu's hand, Sandai carefully looked at this talisman paper that looked very similar to an ordinary detonating talisman.

"Yes, but due to technical problems, this medical talisman can only be produced by me for the time being."

Yu affirmed the problem of the third generation, but he has no plans to hand over the method of making the medical talisman yet.

Just kidding, it took so much time and energy to develop this thing-this is a trump card for him to enter the Konoha Power Center, how can he give it away easily in a short time.

In the words of his previous life, this is his intellectual property and scientific research achievements.

"Great! Your kid is simply a genius!!"

After getting Yu's affirmative answer, Sandai stood up directly from behind the desk.

Medical talisman - this is undoubtedly an epoch-making research and development achievement. If it can be produced in large quantities, the third generation can imagine that the structure of the ninja world may change because of this thing.

"If there's nothing else... I'll go back to Sarutobi-sensei first."

Sensing the excited eyes of the three generations in front of him, I saw Yu rubbing his nose in embarrassment.

He hurried back and spent time making a large number of medical talismans. In the current stage of ninja world wars, practical and convenient ninja tools like medical talismans are undoubtedly in short supply.

"Well...you go to work first."

"This time you have made great contributions to Konoha, and everyone will not treat you badly."

The third generation nodded, waved him to go back, and at the same time his eyes were filled with infinite expectations.

……

By the time Yu walked out of Hokage's office building, it was already evening, and the golden sunset shone across the streets of Konoha.

"Hey, have you heard..."

"That genius Hatake Kakashi was successfully promoted to Jonin yesterday!"

On the way home, Yu heard two Konoha's chunin talking on the side of the road.

"Hey! Of course I heard!"

"I heard you're only 12 years old, right? You're already a Jōnin!"

Hearing this news, I saw another Konoha Chunin with a look of amazement.

Everyone in Konoha knows the name of the genius Kakashi Hatake. He graduated from the ninja school at the age of five. It has always been a record that no one can break in Konoha.

"These brats are really more powerful than each other... I heard that there are even fiercer ones..."

"Three generations of Hokage-sama just accepted his disciple last year... that boy named Yakushi Yu is only seven years old this year, and he is already a special ninja. I really don't know who will be more powerful between the two of them in the future."

Hearing his companion mention Kakashi, the former Chunin suddenly sighed.

Although he is not a ninja of the same generation, he is also a genius boy who is well-known in Konoha. In the past two years, Yu, who has become famous, will inevitably be compared with Kakashi.

"Has Kakashi become a jnin?"

"It seems that the battle of Kannabi Bridge is about to break out... I have to hurry up too..."

Hearing the conversation between the two Konoha Chunin on the side of the road, Yu muttered to himself thoughtfully.

If things develop in the order he remembers, Yan Yin Village in the Land of Earth sent over a thousand ninjas to cross the Ninja Grass Village to invade the border of the Fire Land.

And the yellow flashing Namikaze Minato will lead Kakashi and his three-person team as a ninja to cut off the enemy's backup supply line at the Kannabi Bridge in Kusanagi Village.

This battle will completely change the lives of Kakashi and Obito. In this battle, Konoha will give birth to two heroes with Sharingan. This battle is also a turning point that will determine the development of the entire world.

……

The time is so varied, and the world adds another cup.

Time passed, and the new year came. When the first snow in Konoha's 47th year melted, Yu grew another year.

During this period of time, in addition to daily uninterrupted practice, Yu has been hurrying to make medical talismans.

After a large number of medical talismans were put into the front-line battlefield, the continuous casualties of Konoha ninjas dropped sharply. The convenient and practical medical talismans undoubtedly gave the entire Konoha situation on the battlefield a shot in the arm.

But the long-fermented third ninja world war finally ushered in the final explosion and madness at the end of this coming to an end.

Accompanying the front line came the news that the yellow flashing Namikaze Minato led a successful raid on the Kanna Kun Bridge to cut off the supplies of the land country and repel Iwa Shinobi, as well as the news that Uchiha Obito was killed in battle.

Finally, on this day, Yu received a hasty summon from Sandai and Konoha's senior management.
