I'm doing scientific research in the Ninja World

The next day, Orochimaru and Tsunade came to the training ground at the edge of Konoha early in the morning.

It was called a training ground, but in fact it was just an open space allocated for the Senju clan to train.

"Orochimaru, are you sure you want me to use my full strength? You know my fists."

Tsunade confirmed with Orochimaru again. Although she had accumulated a lot of anger in her heart, she was also afraid that she would use too much force to beat Orochimaru.

"Don't worry, just go all out, I have my own way to deal with it."

Just kidding, if it was the original Orochimaru, he might not fight Tsunade head-on, but now he is eager for it.

After listening to Orochimaru's words, Tsunade no longer hesitated. It was not the first time for the two to spar. Then she rushed forward and punched Orochimaru in the face.

For a moment, the wind swept and the power flew.

Before the fist arrived, the fist wind had already hit him in the face. The legendary strange power is not a false name.

Orochimaru didn't dodge, but he didn't intend to take the blow with his face.

Although Tsunade's movements were fast, they seemed to be slow motion in Orochimaru's eyes.

She easily blocked her attack with her forearm, and at the moment when their bodies touched, Orochimaru's body shook violently.

It swung left and right like a spring, leaving an afterimage.

Tsunade saw Orochimaru take her attack without dodging or evading, and secretly retracted the strength in her hands, but she was also a little surprised to see that Orochimaru only shook a little and quickly returned to normal.

"Heh..., you haven't used your full strength yet!"

Seeing Orochimaru's performance as if nothing had happened, Tsunade no longer held back, and attacked again with a powerful force, which was more ferocious than the previous one.

Orochimaru's body also quickly absorbed the kinetic energy, but with only three punches, the energy absorbed by Orochimaru had reached the upper limit.

And he didn't sit still and wait for death, and began to fight back with both hands.

"Be careful."

Before he finished speaking, Orochimaru jumped up and chopped down with his legs, and Tsunade also jumped away easily.

The next moment, a big hole was kicked out of the previously intact ground.

"When did you learn super strength?"

Tsunade looked at the big hole stepped out by Orochimaru and said in disbelief.

Super strength is something that is innate, and some can be stimulated through hard work and practice. Her super strength is innate, while Sakura in the original work learned it through hard work and practice.

"This is the heart body technique I just researched, and now I can fight you to my heart's content!"

Facing Tsunade who was a little surprised, Orochimaru smiled slightly. The absorption and release of energy will not cause much loss. He can release the energy little by little, or accumulate it to the limit and then release it.

If it is the latter, the power that bursts out can be two or three times stronger than Tsunade's, after all, his ability can be superimposed.

"Hmph, then I'm relieved. It was just a warm-up. See how I knock you down. You were not very polite the other day!"

Tsunade's fingers snapped, and it seemed that she was going to settle accounts with Orochimaru. Women are very vindictive.

The next moment, Tsunade and Orochimaru wrestled again, and it could be said that they were punching each other, and their movements became faster and faster, and even left afterimages in the end.

Tsunade had accumulated a lot of grievances during this period, and she no longer held back after discovering that Orochimaru could completely take her attack.

And Orochimaru gradually became familiar with and adapted to the rapid absorption and transformation of energy. At the beginning, he dodged more, and the more he fought back, the more times he fought back.

The two of them moved around on the training ground, and soon the ground was completely unrecognizable.

"Hey...".

Tsunade punched Orochimaru away, and Orochimaru's body hit a big rock, and the rock had a close contact with his head.

This situation also happens from time to time. If Orochimaru fails to release the energy in his body in time, and the energy absorption reaches the upper limit, he will not force it to absorb, and the situation just now will occur.

"I see that you are not using all your strength, you are killing me!"

Orochimaru struggled to get up from the ground. He looked a little embarrassed, but there were no scars on his body, but a big lump suddenly grew on his forehead.

This is the result of him absorbing most of the energy, otherwise it would be a light head.

Tsunade, who was panting, laughed at Orochimaru's appearance, but tears flowed out while laughing.

Looking at her crazy appearance of crying and laughing, Orochimaru knew what was going on.

He walked up and hugged her gently. Tsunade did not resist, but leaned in his arms and sobbed, completely different from the female Tyrannosaurus just now.

During this period of time, she cried every day.She drinks all day, even frowns in her sleep, and is really under a lot of pressure.

"Okay, okay, it will be fine. I believe he doesn't want to see you in such pain. He will only feel relieved if you are happy."

Orochimaru patted her back gently, like a little girl who was wronged, comforting her in a gentle tone.

"Let's go, go back to eat, and make you some special dishes for lunch today."

When Tsunade was tired of crying, Orochimaru wiped her tears and rubbed her head.

This head-patting killing made Tsunade react. She pushed his hand away and then turned her head to walk towards the village.

"Hehe, woman. You cry when you need it, but you turn your face and don't recognize you when you are not used. You really treat yourself as a tool."

Orochimaru also smiled bitterly. He thought he could hug her more and feel the soft touch more.

"My girlish heart!"

Gently brushing off the dust on his body, Orochimaru followed Tsunade.

For lunch, Orochimaru made three dishes and one soup, braised pork, chicken stewed with mushrooms and a dish of green vegetables. The soup was egg soup. Both the predecessor and the original Orochimaru liked to eat eggs.

The two had been fighting for a whole morning and had already exhausted their physical strength. Orochimaru was fine, as the energy conversion did not consume much physical strength, but Tsunade, that was real physical strength.

Tsunade started to eat before the dishes were served. Tsunade, who didn't like to eat fatty meat, couldn't stop eating after taking a bite of the braised pork made by Orochimaru.

The chicken stewed with mushrooms that came later was even more praised. Fortunately, Orochimaru bought a whole chicken, otherwise it would not be enough for the two of them.

After dinner, Orochimaru pulled Tsunade to find learning materials for him. The content from shallow to deep can help Orochimaru get twice the result with half the effort.

In his previous life, Orochimaru was engaged in biological research, not in agricultural and sideline products, but in viruses, cells, animals, genetic engineering, pharmaceuticals, etc.

With these foundations, he learned very quickly, and this knowledge was constantly combined with the knowledge of this world.

If he really didn't understand something, he would ask Tsunade. Tsunade didn't get impatient, but was a little surprised that Orochimaru asked more in-depth questions.
