I'm doing scientific research in the Ninja World

"Why is the fever so severe? Go get the medical kit!"

Tsunade ran over immediately after hearing the news. She was the one who slept late, but now she was forced to turn on the computer.

After a while, Shizune ran over with a medical kit, her little face full of anxiety.

"Sister Tsunade, what happened to Uncle Snake?"

Tsunade tore off Orochimaru's clothes, measured his heartbeat and pulse, opened his mouth, and looked at his eyelids.

"Huh... The preliminary judgment is that he has a high fever, but there is nothing abnormal in his body."

Tsunade also exhaled lightly, and then took out a few bottles of potion and a syringe. Her skillful movements showed that she was an experienced doctor.

However, after she prepared the potion, her hands stopped moving again. Since she suffered from hemophobia, she has not performed clinical medical treatment.

"Be careful, it should be okay?"

With a mixed feeling of uneasiness and entanglement, Tsunade looked at Orochimaru who was frowning because of discomfort.

She was also determined in her heart. With trembling hands, she slowly approached Orochimaru's arm with the syringe. When the needle touched his skin, Tsunade had already closed her eyes and turned her head to the side.

Relying on her own feelings and years of experience, Tsunade injected the medicine into his meridians.

When she pulled out the needle, she quickly pressed the blood vessel with medical cotton, and threw the syringe aside without even looking at it.

"Sister Tsunade, what's wrong?"

Shizune, who was waiting anxiously on the side, finally dared to ask at this time. She also knew that Tsunade had hemophobia and often taught her medical ninjutsu over the years.

But she was still in the ninja school, and Tsunade only taught her some basic knowledge, which was still far from clinical practice.

She wanted to do it for her, but how could she dare to stab someone right away when she had never held a needle before?

"Let's see if it gets better. If not, we can only go to Konoha Hospital!"

Tsunade, who was still in shock, said with a trembling voice, and her forehead was covered with sweat at some point, as if she had experienced a battle.

Orochimaru knew nothing about these things at the moment. He originally thought that he would be fine after injecting a mild cell fusion potion and sleeping.

Who knew that he, who was as strong as him, would actually have rejection. Fortunately, the situation was not serious, just coma and fever.

This situation would occasionally occur during experiments in the research institute, but compared with other experimental subjects, this was only a mild rejection.

Moreover, his experiments were conducted secretly, and not much data could be collected, so the probability of this mild rejection could not be obtained.

As for Uzumaki Mito's cell fusion potion, it was mild in nature, but that was relative to Hashirama's cell potion.

As the first generation of Jinchūriki, Uzumaki Mito could extract the power of the Nine-Tails to sense the enemy's malice without reaching the perfect Jinchūriki.

When talking about the Uzumaki clan, the first person that Uchiha Madara thought of was Mito. How bad could they be?

To put it bluntly, Hashirama's brilliance was too strong, which overshadowed Mito's strength.

Moreover, this potion was tailored to the individual. Orochimaru's physical fitness was strong enough, but the amount of potion was also more than that of ordinary people. So it seemed that Orochimaru was not much different from others.

After injecting the potion into Orochimaru, Tsunade gave him a physical cooling.

As if the potion had taken effect, Orochimaru slowly opened his eyes not long after.

As soon as he opened his eyes, a beautiful face came into view, with red lips tightly pursed and some tiny beads of sweat on his forehead.

Seeing Tsunade, who was sweating and a little pale, Orochimaru smiled unconsciously.

"Tsunade, why are you here?"

Seeing Orochimaru, who was pale and looked like a human, wake up, Tsunade's hanging heart was finally put down.

"If I hadn't come, your brain would have burned out!"

Tsunade rolled her eyes at him unhappily. She mustered up unprecedented courage to give him an injection.

"I'm fine, just a little weak..."

He coughed twice as he spoke. People who didn't know would have thought he was already terminally ill.

"Uncle Snake, are you okay? Are you feeling better? Sister Tsunade just gave you an injection!"

Shizune on the side also stretched her head over to show concern. Orochimaru smiled at his concerned expression.

"With your sister Tsunade here, I won't die."

Hearing that he kept talking about death, Tsunade glared at him fiercely. If Orochimaru really died, wouldn't the cursed necklace that he took away come true?

He didn't expect that injecting a potion would almost burn out the CPU!

"Okay, Shizune, go to the ninja school. I'm here."

"Oh, bye, Uncle Snake. I'll come back to see you after school!"

Shizune, who was sent to school by Tsunade, walked out of the room reluctantly., she thought she could take the opportunity to skip class, but it seems that it has failed again.

As for her breakfast and lunch, she would not die from starvation for a day, and she still had a lot of pocket money.

"Tell me if you feel uncomfortable, I am a doctor after all."

Orochimaru looked at her still unnatural face and knew her dilemma.

"It's rare to see you care about me so much. If I had known, I would have been sick often."

"What nonsense are you talking about? You still have the energy to talk nonsense. It seems that you are fine. I'm leaving!"

She stood up and pretended to leave, but Orochimaru grabbed her hand.

Feeling Orochimaru's pull, Tsunade sat back again.

And Orochimaru did not mean to let go, but held tighter, as if he was afraid that she would leave suddenly.

Feeling Orochimaru's somewhat warm palm, Tsunade's cheeks were also slightly red. She struggled for a while but failed to break free, and she didn't dare to use too much force for fear of pulling Orochimaru.

Seeing that the struggle was fruitless, Tsunade glared at him fiercely.

But Orochimaru ignored her threatening look. He was a patient now, and he still wanted to beat the patient? Patients have no human rights?

"Okay, I won't leave, you let go first!"

Seeing Orochimaru's dead pig fearless look, Tsunade could only be the first to give in.

Hearing this, Orochimaru slowly let go. Tsunade, who regained her freedom, rubbed her wrists and crackled her bones.

"I'll remember this beating for you, and I'll settle with you when you recover!"

"Okay, I won't agree if you don't do your best by then!"

Orochimaru also said in an unyielding manner, just kidding, when he recovers, his physical fitness will definitely improve to a higher level, and then he can use this free labor again.

"Why did you have a fever? You look quite strong, is it just a superficial thing?"

As she said this, Tsunade didn't forget to glance at his abdomen, obviously saying that his eight-pack abs were just for show?

Orochimaru heard her sarcasm and could only speak helplessly:

"You must have been too tired recently, and your body can't take it anymore."

Hearing Orochimaru say this, Tsunade didn't say anything else, but just sighed heavily!
