Uchiha from the Country of Rain at the start

At the Heretic Golem, Obito took off his mask, revealing his youthful face on one side and a face full of white wrinkles on the other.He looked at his right arm gradually in trance. He didn't know how many times he had done this.After getting this body, he witnessed Lin's death and his mentor's death. Now this pale body reminded him all the time that he was living in hell.

"Don't worry, Lin, Minato-sensei, I will let you reappear in my world."

At this time, Zetsu's body was slowly pulled out from the ground.

"Jue, is the matter done?"

"It's done Obito." Zetsu held a test tube in his hand, which contained Uchiha Rain's blood.

"Well, let's take it and study it. Why can only Uchiha Rain's body activate his Sharingan? I've never seen this happen before. Is it because of his special body?"

"I don't know, but this reminds me of someone." Hei Jue suddenly spoke.

"Who?"

"Senju Hashirama, but let's wait for the research results to come out before making a conclusion."

The two went to the laboratory under the Heretic Golem, which was left by Madara during his lifetime and contained many dormant White Zetsu clones.

"Although I'm not very good at it, there is no problem in studying individual cells." Bai Jue said to himself, and he began to take samples from the blood for observation.

"Well, let me take a look, uh, let me look for it, uh... look again... how is it possible!..." Bai Jue observed these cells with a microscope, but his expression became more and more shocked.

"What's going on, Zetsu!" Seeing Bai Zeze's appearance, Obito's heart became excited.

"These cells are all dead!"

"What do you mean?" Obito knew nothing about cell research.

"It shouldn't be. This is a blood sample from the battle. It hasn't been long. Normal people's cells are always in a metabolic state." Bai Zetsu looked at Obito's confused eyes.

"Well, this is a bit complicated to explain. How can I put it? There are always living cells in everyone's body, and there are always dead cells, but living cells can still be found. How can it be possible that all of Uchiha Rain's cells are dead?"

"Obito, please go get some new samples."

after awhile.

"Quick, quick, quick, this is the blood on Uchiha Yu's bandage."

Bai Jue took samples and observed them. "Incredible! His cells were dying quickly after leaving the body." Soon there were no living cells in the field of vision.

"No wonder his Sharingan is degenerating. Why is it like this? It's so weird." Bai Zetsu murmured. At this time, Black Zetsu suddenly remembered a situation. This kind of ability that seems not to belong to this world can only be found in the Otsutsuki clan. It can only be seen on the body, but Black Zetsu immediately rejected the idea. Uchiha Rain did not have the aura of the Otsutsuki clan on his body.

……

At this time, Rain was still lying on the experimental table. He did not have Hashirama cells, nor did he have the physique of the Uzumaki clan, and the wounds on his body were still painful. At this time, Uchiha Rain did not know the real reason why Obito returned the Mangekyo. He thought that Obito returned the kaleidoscope. It was under the pressure of Tiandao and Xiaonan that he compromised in order to continue the plan for peace in the ninja world.

I didn't expect that he would return to the Akatsuki organization in this form. With Obito's ability, I am afraid that all three of Yamashita Nazawa would have died in his hands.

At this time, Konan walked in with food. Ninjas also wanted to eat. Tiandao took the food and left, probably giving it to Nagato himself.

Xiaonan opened the food and divided it carefully, including dumplings, dried meat, and a little pickles.

"Uchiha Yu, I'm sorry. We don't have extra money to spend on food at the moment. This is what we eat, and it may be much worse than the food you had in Konoha."

"Teacher Xiaonan, isn't this the meal that the four of us often had before? It was a time that I miss very much. Why do you have to say sorry to me?"

"Yes." Xiaonan's hand paused slightly.That time? It's a pity that it will never come back.

"If it's not convenient for you to get up, I'll feed you!"
