Nanoscale parasites.

A poisonous insect that is extremely small to the nanometer level is equivalent to a highly active toxin, and when others are infected with this toxin, they will soon die due to the destruction of cells in the body.

So in the past, the oil girl had to wear protective clothing that covered the whole body, just to avoid accidentally injuring her companions...

But that's all in the past, with the help of Orochimaru's training, the nano-level parasites in his body have more of a simulated parasite, even if they accidentally invade their companion's body, they will not destroy the cells in their companion's body, and thus die of poison.

This made Oil Girl Harone not have to wear that kind of full-body protective clothing from now on, so he was grateful to the fifth Hokage-sama.

And his father, the oil girl Shiguro, who also has nano-level parasites, is the same, so that their father and son have walked out of the predicament of the past, and their father and son are really grateful to the five generations of adults!

After all, the feeling of being isolated by protective clothing itself has a feeling of being isolated from oneself and one's companions, and it seems that it is impossible to get along closely.

It's not a good feeling.

And even more than that.

"Let's learn about the human body and medical ninjutsu." Orochimaru said with a smile, "Manipulation of the inside of the human body at the nano level will have an extremely effective effect if it is applied to medical treatment. If you can directly strangle the virus, protect the fragile organs, and apply medical ninjutsu to this level, you will be able to carry out more refined medical healing operations, and in this way, you can also master the unique insect medical ninjutsu and become a great medical ninja. ”

The oil girl took the root and nodded solemnly, it was also something he hoped for to be able to use medical ninjutsu to help his companions.

"And it's not just the medical field." "If we can achieve in vitro activity and further simulate the properties, we can obtain materials with excellent properties composed of nanoworms," Orochimaru said. The strength of nano-scale materials can cause extremely strong destructive effects even at the material level, and can also have a strong defensive effect. Now that there are signs of a breakthrough in in vitro activity, if you strengthen the exploration of nature simulation, when the time comes, your insect ninjutsu can also be offensive and defensive at the material level, which can not only spread poison, but also heal and heal yourself. It can also detect and explore, and it can also strengthen its own body structure and exert its powerful physical ability. ”

All of this is foreseeable by Orochimaru.

By that time, Oilgirl Takine was an invulnerable, and strangely powerful ninja.

Of course, this is still one aspect.

On the other hand, nano-scale operations can assist Orochimaru to better conduct biological and material research.

So in his opinion, the oil girl is really a rare treasure.

And hearing what the five generations of adults said, the oil girl couldn't help but think about it, and then she was more motivated to study and study with Lord Orochimaru.

He also wants to be a powerful ninja in the village.

Seeing that the child was encouraged to become more and more serious, Orochimaru smiled and nodded.

Children, it is necessary to motivate from time to time.

Land of Rain.

Tsunade looked out the window, the sun was rare and sunny at this time, but it wasn't Sunday.

Usually in Yuyin Village, it doesn't rain on Sundays.

Is this a special gesture of goodwill?

After all.

"Today is the wedding day of the old man's son." Tsunade sat and looked at the bottle not far away.

"Really, you can't go back and celebrate a day like this."

He had already noticed that the guards on her had been released, and even the seal in her body had been lifted, which meant that she could leave at any time.

But she can't go, she needs to stay and continue to maintain the current situation.

It seems that because there are more terrible enemies lurking, the village is not willing to destroy the situation easily.

So even if she can go, it's better to stay.

For the sake of the overall situation of the village, Tsunade of course had no choice but to stay.

Knock knock.

There was a knock on the door.

"Come in."

The door opened, and a woman with light blue-purple hair, a ball head, and a pale blue paper flower on the right side of her head.

"It's you, one of those three little guys."

Tsunade, who had already guessed, easily recognized it.

At the beginning, the three imps who came up on their own initiative, when Orochimaru proposed to kill them, but was stopped by Jiraiya.

This is one of the little girls, a disciple of Jiraiya Professor in the Land of Rain.

"Tsunade-sama."

Xiao Nan shouted respectfully.

There was no shelf at all, and it seemed very low.

Tsunade immediately realized.

"Are you asking me for something?"

This is clearly a demanding attitude.

"I'd like to ask Tsunade-sama to treat a patient."

"Patients? Someone important to you? What about the other two? Orange-haired, or red-haired? ”

"Please come with me, and you'll be clear." Xiao Nan said solemnly.

Tsunade put his face on his hand and got up.

"Lead the way."

Xiao Nan breathed a sigh of relief.

"Please follow me."

Konan walked out of the room, Tsunade following behind.

Soon after, they got into an elevator, sank, and entered a cavern where they found a hidden passage.

In this process, Xiao Nan made seals from time to time, revealing the camouflage of some ninjutsu enchantments.

After passing a lot of well-sealed and well-camouflaged levels.

Finally, they came to a secret room.

As the chamber opened, stepping into it, Tsunade saw that one was on a shelf, as if he was restrained, with a lot of black rods stuck in his back, skin and bones, so weak that he was almost human, and his red hair was dull and dull.

It's like someone who has been severely tortured.

“…… Your situation is very bad, as if you have been squeezed out of your vitality for a long time. ”

"Tsunade-sama, I'm smiling." Nagato's tone was gentle, without any condescension.

He no longer wants to call himself a god, and he also has a lot of respect for this ninja medical saint who single-handedly established a complete medical system.

"This should be your weakness, so let me in here."

"It's also to show you sincerity."

"I have received this sincerity, so let's start the treatment."

Tsunade rolled up his sleeves and walked over.

Xiao Nan hurriedly followed with some nervousness.

Although calling Tsunade to come over for healing was something she had repeatedly requested.

However, the weak Nagato was indeed exposed in front of the eyes of others.

Although Nagato is not without the ability to protect himself.

However, when it comes to medical treatment, it is necessary to cooperate, so during the period of treatment cooperation, it is definitely necessary to let go of some precautions.

There is no doubt that it is an adventure.
