I'm doing scientific research in the Ninja World

Just as Orochimaru was watching intently, Tsunade stood up shakily, and her fingers accidentally knocked over the empty wine glass, making a crisp sound.

"Do you want me to carry you back?"

Orochimaru was in a good mood at this time, and teased with a smile.

And Tsunade glared at him fiercely when she heard the tiger and wolf words from Orochimaru.

"You still want to take advantage of me, am I drunk or are you drunk?"

As she spoke, she staggered into the room and slammed the door shut with a "bang".

The next day, Orochimaru came to the training ground as usual.

But in addition to him and Tsunade, there were Jiraiya and Shizune, who was more than four years old.

"Sister Tsunade is so powerful, and Uncle Orochimaru is also so powerful."

Shizune, who could already remember things, clapped her hands while watching the two people fighting in front of her, with stars in her eyes.

"Shizune, why do you call Tsunade sister and Orochimaru uncle?"

Jiraiya looked at Shizune curiously at this time. Do the two look so different in age?

"Sister Tsunade is sister. She asked me to call her that."

Jiraiya's mouth twitched after hearing this. The innocent Shizune was still too simple to believe in other people's sweet words.

Tsunade, Jiraiya, and Orochimaru were all born in Konoha in the 10th year. They are only 27 years old now, which is the age of youth and vigor.

However, after experiencing the baptism of war, they are much more mature than their peers.

At this time, the two people on the training ground were fighting fiercely. After two and a half years of practice, Orochimaru already knew this body very well.

From the beginning, he could only take three punches and two kicks from Tsunade, but now he can take fifty or sixty moves before reaching the limit.

While the body is rapidly converting energy, Orochimaru will break through the upper limit of cell energy again and again.

However, after absorbing the energy of Tsunade's fifty or sixty punches, he dared not break through the upper limit, because the cells in his body could not store more energy.

It's like the original body just broke through the shackles, but there is always a bottleneck period, and if you want to break through this bottleneck further, you have to raise the upper limit of the body.

Either after years of energy nourishment, this is still too slow for Orochimaru; or like the Black Emperor, he can evolve again through the empowerment of the potion mother vine to improve the upper limit and absorption capacity of the body.

At present, Orochimaru can only absorb kinetic energy through physical contact, and he can't do anything about the surrounding magic energy such as fire, magnetism, gravity, etc.

Even if he can absorb and transform, the efficiency is very low, not to mention using it against the enemy.

This is why Orochimaru has been pulling Tsunade to fight.

"Okay, Tsunade, let's stop today's training!"

Looking at the turbulent Tsunade, Orochimaru was a little reluctant but had to stop.

Another benefit of sparring with Tsunade is that you can feast your eyes. The trembling white rabbits on her chest are really dazzling, and at the same time, people can't stop, hoping that she won't stop.

But even a pervert like Orochimaru can't bear Tsunade's violence. Although the scenery is beautiful, life is more important.

"Hey, why are you so weak today? You gave in so quickly?"

Tsunade said to Orochimaru with her hands on her waist and panting, her chest still undulating.

"That's it for today. You take Shizune to buy clothes first."

Hearing Orochimaru's words, Tsunade no longer wanted to fight. She patted the dust on her body and walked to the sidelines.

Today, Orochimaru didn't fight back many times, mainly because he was beaten more.

It's not that he has any hobbies, but that the energy of his body has reached the upper limit, and no matter how much he absorbs, he can't break through the bottleneck.

This situation has been going on for a while, making him realize that this is the limit of this body.

Knowing this, he naturally had no intention to continue, so he just found an excuse to get away with it.

"It seems that the future goal must be to focus on research! It just so happens that the cells of Hashirama and the Uzumaki clan are already in hand."

The next step is to merge these two immortal bodies first. I believe that with my two lives and doubled understanding, I can research a new path.

Although Orochimaru in the original work was also engaged in human body research, his research direction was wrong. When he defected from Konoha, he had already started research on reincarnation.

"Hey, Orochimaru, is this the physical technique you researched? A physical technique for getting beaten? It looks good!"

Just when he was determining his future goals, Jiraiya's sarcastic voice came over.

At this time, Tsunade had already walked back with Shizune, but Jiraiya was still mocking Orochimaru on the spot.

Facing his contemptuous, disdainful, and questioning look, Orochimaru didn't waste time talking to him.

Instead, he came to his side andA head bang hit his forehead.

The next moment, with a "biu" sound, Jiraiya screamed, and his body flew back five or six meters uncontrollably.

"If you don't accept it, you will practice with me in the future!"

Jiraiya, who was cursing on the ground with his forehead covered, curled his lips after hearing Orochimaru's words:

"You are so good, Orochimaru, taking advantage of others' misfortune to launch a sneak attack. It's true that you are a lotus root growing in a stinky ditch, full of dirty thoughts!"

He stood up from the ground, looked at Orochimaru aggressively, and continued:

"I want to see if you have improved in these years, just to get back at yesterday's place!"

Orochimaru knew that he was talking about the beating he had done yesterday, and he also lost face in front of Tsunade.

"I'm not free today, let's do it another day!"

Orochimaru ignored his protests, closed his eyes and walked back, pretending to be gone, and pissed you off.

He had to go back to continue his research, and didn't want to waste time on these meaningless discussions.

The doubled comprehension he had just obtained made him think of more conjectures, all of which needed to be verified one by one on the experimental table.

On the other side, Tsunade pulled Shizune towards the village mall.

"Sister, you are so powerful! I want to be as strong as you in the future."

Shizune, who was still a half-grown child, was looking at Tsunade with admiration, her eyes full of longing.

"Haha, okay! Sister, I will be even more powerful! I will teach you when the time comes."

Tsunade only showed her gentle side when she was with Shizune, and it can be said that she gave all Kato Dan's love to her.

"Wow, there is something more powerful, is it medical ninjutsu?"

Hearing medical ninjutsu, Tsunade's eyes were a little dim, and then she nodded to her firmly and touched her little head.

Since she suffered from hemophobia, she has not had any surgery and has not entered the kitchen, but it does not prevent her from pinning her long-cherished wish on Shizune.

I can be her assistant in the future, and I can be the one who performs the operation for her.

"Girls should be gentler. Learn medical ninjutsu!"

"Okay, okay, I'll listen to you, sister!"
