Guinea Pig in the Laboratory

The crow's training could not be completed overnight. Now, he had to deal with something troublesome.

He had not forgotten what he had promised Tsunade. Unfortunately, when You was not training at the Uchiha Compound, he was following Orochimaru on missions.

This had greatly slowed Tsunade's research progress.

"Lady Tsunade, please listen to my explanation! I had my reasons!"

Uchiha You swallowed. Just moments ago, a fist the size of a sandbag had slammed down beside his ear.

The explosive sound made his ears ring. He turned his head slightly and found that the wall behind him was gone.

The nearby ninjas thought they were under attack and hurried over to investigate. The moment they saw Tsunade disciplining someone, they immediately slipped away.

They wore pitiful expressions, yet none of them dared give Uchiha You a chance to call for help.

What a joke! Tsunade's status was not something an ordinary ANBU member like them could interfere with.

"Hehe, so your wings have grown in already? You no longer listen to orders? It has only been a few days, and your answer is that you were improving your strength? You even shut your door and refused to see me?"

Tsunade grabbed Uchiha You by the collar. An aura of death surrounded her, and he truly feared that she would punch him in the chest.

There was precedent for this! Jiraiya was the best example. People could die!

"Of course not. This involved Sand Village, so everything had to be prioritized. I was following my teacher Orochimaru's orders."

Upon hearing that it involved Sand Village, Tsunade finally put him down.

"I'll give you one chance. If this happens again, you're dead!"

"Besides, I did not call you here to experiment on you. I want you to study Medical Ninjutsu under me. Recently, every ninja who has learned the Healing Technique will undergo a period of concentrated training."

After briefly explaining the Medical Corps' arrangements, Tsunade had to acknowledge Uchiha You's talent for Medical Ninjutsu. He was a rare medical talent.

At that thought, Tsunade felt even more resentful. According to the team assignment back then, Uchiha You was supposed to be taught by her. Yet he had ultimately been assigned to Orochimaru. What a waste of resources!

How could someone as cold and detached as Orochimaru possibly know how to teach students?

Tsunade led Uchiha You into the classroom, where only five people were waiting for her.

"Lady Tsunade!"

"Lady Tsunade!"

"Good morning, Lady Tsunade!"

Unlike Uchiha You, who had arrived late, the people selected to become medical ninjas had come to the classroom immediately.

Being able to study under Tsunade was a blessing!

"Hello, everyone."

After a large-scale screening process, only a handful of people met the requirements. Even so, Tsunade was ecstatic. She believed Medical Ninjutsu would certainly flourish in Konoha.

Her gaze settled on them as Tsunade began teaching Medical Ninjutsu anew.

You was essentially reviewing what he had learned. Many of the points Tsunade taught were things he had studied as a child.

After a full day of classes, Uchiha You's head was spinning. He wanted nothing more than to find somewhere to collapse and sleep.

"Lady Tsunade, why have they all left while I still cannot go?"

He shot her a resentful look. Tsunade had him completely in her grasp; after all, one could hardly refuse someone after accepting their favors.

He had learned the Healing Technique and the Monster Strength Fist. Although he had won them through a bet, You was still not satisfied.

He wanted more, such as the advanced Mystical Palm Technique and Chakra Scalpel. At present, only Tsunade knew these advanced Medical Ninjutsu.

"Why would I let you leave? Go inside and take off your clothes."

"?"

Uchiha You took a step back. He was only ten years old, and he hurriedly refused.

"This is a crime..."

Smack!

Tsunade slapped him on the head and said with a dark expression,

"Take off your upper body clothes! Idiot! I need to examine you! Did you fool Nawaki into wearing weighted gear last time?"

"Weight on that monstrous level is not something someone your age can handle."

Staring down at Uchiha You, Tsunade knew that such heavy weighted gear could crush someone to death. Yet according to Nawaki, when Uchiha You removed his weights, they had been even heavier than his.

Nawaki's words had piqued Tsunade's interest once again.

She suspected that the reason his body could achieve such things was because it contained an unknown substance. This unknown substance allowed Uchiha You's body to rapidly grow stronger and repair damaged injuries.

"That bastard Nawaki. I did not expect him to actually go and do it after returning."

Damn it, Nawaki. Did you have to do it right in front of Tsunade while training?

Now I've become Tsunade's experimental material!

Thinking of his little white rabbit, he feared he would soon suffer even worse than it did.

His heart hardened. The next time they met, he would definitely teach Nawaki a good lesson!

"Yes. If I had not been there, that brat would never have gotten back up."

There were several weighted tools beneath the table. Tsunade put them on Uchiha You, and when she saw that he could walk normally, she knew Nawaki had been telling the truth.

"Lady Tsunade, there is no need to be surprised. You adapt to this sort of weight gradually. Nawaki merely wanted to reach the sky in one leap. It requires long-term, persistent training, and it will noticeably improve taijutsu."

You thought of a taijutsu genius. Judging by the man's age, though, he should have only just been born?

"There is a Genin in the village named Might Duy. He is a taijutsu genius. When he unleashes his full strength, he can even display power no weaker than Kage-level!"

"Hmm?"

Listening to him, Tsunade had not known that the village possessed such a strong fighter.

She herself was considered an accomplished taijutsu practitioner, but she still relied on Chakra's special techniques for exerting force.

The Hyuga Clan likewise relied on the special techniques of Gentle Fist to deal with enemies.

She acknowledged that taijutsu was an inseparable part of a ninja's abilities, but compared with powerful ninjutsu, one could not gain the ability to fight Jonin through the body alone.

"When I have time, I'll look into him."

"And stop changing the subject. I need to examine you."

Unfortunately, she found nothing in the end. Looking at the equipment in Tsunade's laboratory, You saw that it was already quite sophisticated, but it could not detect radioactive elements. It would only reveal their effects on the body.

"By the way, Lady Tsunade, I need to borrow your laboratory to conduct some experiments."

Although radioactive elements could not be detected, cellular changes could still be observed. Uchiha You needed to use the equipment to examine the Healing Technique's capabilities.

Destroying and reconstructing cells were both extremely dangerous matters. Without precision equipment, it would be impossible to accomplish.

"You want to borrow my laboratory?"

Tsunade gave him a suspicious look and said with slight displeasure,

"You are Orochimaru's student, so why do you need my laboratory? I remember Orochimaru has plenty of experimental equipment."

It was not that he did not want to borrow it. Even though Orochimaru was his teacher and his personality had not yet become twisted, if he were discovered, he would definitely be strapped to the experiment table.
