Naruto: My and Obito's mutual redemption

Since returning from the last hot spring trip, Yuyan always feels that Obito is more attached to him than before, and now he seems to be much more sensible. He used to have to be called three times before he would get up, but now sometimes he can get up after being called twice. Well, there is progress!

During this time, Kakashi was also busy practicing his swordsmanship and had no time to pay attention to them. When the class was over, fewer people came to surround Yu Yan, although a large part of the reason was that the powerful "resentment" emitted by the puppy drove them away... Yu Yan was of course happy to be free.

Yu Yan has come to some conclusions in his research on "Ninjutsu Reconstruction and Creation". Just as he thought, he can indeed create new ninjutsu through his own understanding, but it is still limited to the conventional five elements escape technique for the time being.

Recently, Yuyan is in a good mood and has more time to accompany Obito every day. He plans to develop the composite ninjutsu that he had thought of before with Obito. He said before that he would develop it before going to school, but later he found that he thought too simply. However, now that he has a new understanding of his research, he can give it a try.

But before that, Yu Yan had to visit Orochimaru, whom he hadn't seen for a long time. After all, they were nominally master and apprentice, and he was also very curious about whether Orochimaru had made any progress in his research on his blood cells, and by the way, he wanted to say something good to stimulate the snake.

Today is the weekend and the sun is shining brightly, just like Obito who is still sleeping beside me, making me feel warm on the body.

He got up early to cook, but he didn't wake up Obito immediately, wanting him to sleep a little longer. He finished his breakfast alone, left another portion on the table, and left him a note before going out.

The first thing to do today was to find Orochimaru. With the experience of his last visit, Yu Yan finally reached his snake den after a long and winding road.

He stepped into the dark underground base and walked through another strange road before finally reaching the door of his laboratory in the dark.

Yu Yan knocked on the door twice, but found no response, so he pushed the door open and walked in. What caught his eye were more bottles and jars than last time, each filled with colorful mysterious liquids. Among the pile of glassware, Yu Yan finally found the man with long straight black hair.

Orochimaru was fully focused at the moment and didn't pay any attention to Yu Yan who came in. He fiddled with the instrument by himself, carefully pouring a drop of red liquid into another test tube containing white liquid.

"boom!"

After a violent reaction, the test tube shattered, and it was obvious that the experiment had failed.

Orochimaru was not in a hurry. He slowly raised his tired eyes and saw that the person coming was Yu Yan. He greeted Yu Yan excitedly: "You are here, Yu Yan-kun."

"Excuse me for disturbing you, but I wonder what topic Lord Orochimaru was researching just now?" Yu Yan asked indifferently.

Orochimaru's eyes showed a hint of fanaticism when he heard this: "You know, Yuyan-kun, you really won't disappoint me. There is a strange energy in your blood. Although it is not quite the same as Hashirama's cells, my experimental results show that there are some similarities between the two."

"I'm of the Thousand Hands bloodline, so it's normal to have some similarities, right?" Yu Yan asked.

"No, no, I have also studied the Senju bloodline. Your blood is obviously not on the same level as ordinary Senju! On the contrary, like Hashirama's cells, it has a very powerful vitality." Orochimaru explained.

Yu Yan pondered for a moment, this is a bit strange, the reason why Hashirama's cells are so powerful is because of Hashirama Senju's sage body and Asura's chakra. But Yu Yan doesn't have either of these two now, even if he really has a sage body, he definitely doesn't have Asura's chakra, so what's the problem?

Seeing Yuyan's silence, Orochimaru continued to explain: "My guess is that the vitality contained in your cells is probably different from Hashirama's. The vitality of Hashirama's cells seems to be the strength of the body, while your cells give me the feeling of... the strength of the soul."

Yu Yan was stunned. Is that so? He knew that although his soul was special, he could also change his physique. He thought he had never thought of this.

After a moment of silence, Yu Yan said, "How about this, I'll leave some more blood for you, and you can continue your research. I came here today to tell you something."

Orochimaru's eyes flashed with brilliance. He immediately replied, "That couldn't be better."

"The forbidden technique you are researching, Reincarnation without Corpse, can indeed allow you to achieve a certain degree of immortality by changing your body. But you have overlooked a fatal problem, which is the soul. Every time you reincarnate into a new body, the mixed memories of the original owner will wear away your soul. It's okay once or twice, but if it happens too many times, your soul will no longer be complete, and your research will come to an end."

"What did you say!?" Orochimaru was shocked, not caring how Yu Yan knew the forbidden technique he was studying, and even the name matched. The key point was that there was a problem with this technique, and it was very deadly.

After hearing Yu Yan's words, he realized that he had not considered the issue of soul consumption. He suddenly became a little anxious. If this technique didn't work, would eternal life be a pipe dream?

"I know you're anxious, but don't be impatient. Just listen to me." Yuyan found Orochimaru's violent reaction a little funny, but still planned to tell him the solution.

Yu Yan continued, "Since it's a deal, I'll tell you the solution, and you have to help me research some things, okay?"

"You tell me! As long as you can help me solve this problem, I will definitely help you with all my strength. As long as I can do it." The eagerness in Orochimaru's eyes almost penetrated Yu Yan.

"Uh, okay. Actually the solution is very simple. Use Hashirama's cells and your own cells to create a container for reincarnation. This way you don't have to face the problem of your soul being erased by memories." Yu Yan said, spreading his hands.

Orochimaru thought about the feasibility of the plan, and then asked: "But I haven't yet developed a plan that is perfectly compatible with Hashirama's cells. Without a successful product, it's difficult for me to do it. And although there is no soul loss, according to what you said, even if the body is perfect, the soul will still lose a part, even if it is very small."

"Well, regarding the successful product that is compatible with Hashirama's cells, I do have some ideas. You may not know that there is a creature that is replicated using Hashirama's cells. Don't worry, there are 100,000 of them."

"How many? One hundred thousand?"

"It's a creature called White Zetsu, in human form I guess... I'm sure you'll get some inspiration from catching it in the future. As for the soul, I think you can continue to study my blood, maybe you'll gain something. Even if you can't figure it out in one go, I can use my soul power to keep you safe." Yu Yan expressed his thoughts, and now it was up to Orochimaru.

Orochimaru quickly brainstormed and felt that Yuyan's plan was feasible. Yuyan's soul was so powerful that it made his scalp tingle. Moreover, if there really were so many of that thing called White Zetsu, maybe he could really create a perfect body.

After thinking it over, Orochimaru nodded in agreement: "Okay, I think your plan is feasible, but I don't know what your requirements are?"

"All I ask is that you study something related to the Sharingan, but it will probably only be effective after you understand Hashirama's cells and my cells. The purpose is naturally for the child in my family. There's no rush, just do what you want."

Yu Yan did not immediately ask him to start studying the Sharingan. After all, it would be meaningless to study the Sharingan without studying Hashirama's cells, and he couldn't do it.

It is not known whether Orochimaru came up with useful results first or Obito opened his eyes first. However, in order to make his Mangekyo always bright in the future, it is necessary to study Hashirama's cells.

"Okay, I understand. Remember to bring Uchiha blood next time." Orochimaru said and was about to continue his research.

Yu Yan thought for a moment, then said with a wicked smile: "Let's leave it at that for now. There is one more thing. You are my teacher, so don't you have anything good to give me? For example, ninjutsu or something like that?"

Orochimaru's mouth twitched. Who was it that said he didn't want a ninjutsu? He even took one of mine before he left last time. Don't think I don't know...

Orochimaru patiently asked, "What ninjutsu do you want? Forget it, in the next room, there are ninjutsu I collected, if you want to see it yourself."

"The spiritual scroll is with you. Lend it to me." Yu Yan didn't bother to be polite with him and went straight to the point.

Orochimaru glanced at him, but still took out the contract of Ryuchi Cave and said, "Here you go. Just write your name on it."

After writing his name, Yu Yan said goodbye. Orochimaru seemed to be in a hurry to start his research. But before leaving, Yu Yan left a tube of blood for him, and then ran to the next room to choose ninjutsu.
