Countless philosophers in previous lives have tried to figure out what the intangible things like spirit and soul are.

Influenced by his previous life education, it was inevitable that Shuimu was more inclined to physicalism. It was natural to understand psychology and physics, body and mind as a whole; to regard psychology as a branch of physics and try to explain it.

Only by reducing all psychological, spiritual and even soul phenomena from a physical scientific perspective can a unified theory be developed. Until Shuimu traveled through time, he had no doubts about it.

After traveling through time, Shuimu also tried to explore the connection between the spirit and the body for a long time. It was because of the magical thing called chakra that blurred the boundary between illusion and reality that he once thought he had found the key.

After nearly a year of exploration, I have achieved a lot, and even many of my old ideas have collapsed. For Shuimu, who has accepted and firmly believed in dialectical materialism since childhood, it is really a bit difficult to explore the power of spirit and soul.

Until recently, Shuimu gave up the idea of ​​thoroughly understanding things like consciousness and spirit. Quantum consciousness, quantum entanglement, and superposition? Well, with Shuimu's knowledge, he only knows these terms. As for research, it would take at least a rare genius once in a century to devote his entire life to achieve something. It's better to leave these troublesome problems to the truly smart people to figure out. I just need to know how to use them.

The Eight-Headed Technique is the essence of Orochimaru's decades of research.

Throughout Orochimaru's life, his thoughts changed greatly. When he was young, he was a talented and enthusiastic young man. However, in the years of war, he gradually lost his childhood innocence. The baptism of blood and fire made him selfish and egoistic. His curiosity about the unknown and fear of death led him astray. He achieved miracles that ordinary people could hardly imagine, such as Snake Fairy Technique, Curse Seal, Reincarnation without Corpse, Eight-Headed Technique, Impure World Reincarnation, etc. The final failure of Kabuto Yakushi, who accepted all his inheritance, made him give up his once ridiculous ideas, and instead turned over a new leaf.

Of course, the last one is still questionable.

Although Orochimaru achieved his goal of immortality, it is undeniable that he never had a belief that allowed him to carry it out unwaveringly. The Yamata no Orochi is indeed Orochimaru's obsession, but its foundation is not the obsession, but Orochimaru's self-awareness.

Obsession is also a part of the spirit, and everyone has it to some extent. Under the influence of Chakra, people with strong wills are more likely to manifest the power of obsession.

The size of the power is not the key point. The obsession varies from person to person. Orochimaru takes the uniqueness of his own existence as the foundation and hides it in the curse seal, so he can have countless incarnations. Unless all the curse seals disappear, he cannot be considered completely killed.

The most dangerous point here is to define the boundaries of self-cognition.

Orochimaru's original experience, what the Yamata-no-Orochi saw and heard in the Heaven's Curse Seal, the memories of his various clones, and even the obsessions of others that he devoured through Reincarnation of the Undying Corpse, all were regarded by Orochimaru as a part of himself.

Fully affirm your own existence, understand that human nature is gradually changing, and accept every change of yourself. But there is one thing that you do not approve of, that is, false memories and imposed thoughts, such as illusions; or the erosion of natural energy, such as the risky Sage Mode.

“Is there a definition of the scope of self-awareness?”

Mizuki's original form asked hesitantly.

"I know all my physical clones have thought about this, but you never reminded me!"

The physical clone behind him was paying attention to the not-so-distant front.

"We can think about it, and it doesn't matter if you know it, but we can't bring it up. Otherwise, will you think we have ulterior motives?"

There has already been a physical clone whose thinking deviated and almost caused a major accident, so the credibility of the physical clone has always been in doubt.

"Do you think Orochimaru's statement is credible?"

"I think you already know the answer, but you just don't want to accept this reality."

"Yes, I am the hypocritical one."

Mizuki's true form muttered.

"Although I have not forgotten my past life's experiences, I have gradually forgotten my past life's name."

Some words will become unfamiliar if you don't use them often. If someone calls you by your past life name, you may not be able to react immediately.

"My name is Shuimu now, and I also gave myself a last name - Lin."

The clone waited for Mizuki's original self to finish talking to himself before interjecting.

"Humans receive information from the outside world through vision, hearing, taste, smell, touch, and intuition. These are all the senses we use to observe the world and form self-awareness. In the previous life, there was no supernatural power. All sensory reactions were transmitted through nerve signals. The transmission speed was extremely fast, infinitely close to light beams, but there was also a time difference. In other words, thinking and senses were not synchronized. Because supernatural power does not exist, once a part of the body leaves the body, it will naturally not be considered as part of oneself."

"But the ninja world is different. Shadow clones are created as extensions of one's own will, and there are indeed some risks involved. As the original body, you have a completely different concept from the natives of the ninja world. You have never regarded the shadow clones as a part of yourself, but as tools such as swords, guns, sticks, etc. Asynchronous consciousness? Even if there is a time difference between your original body's sense of touch and thinking, the difference of the shadow clone is just that this time difference is greatly magnified. As for the risks..."

The clone said helplessly.

"It's like a hand. Every cell in it has a tiny chance of becoming cancerous, but can you not regard this hand as a part of yourself?"

"After traveling through time for so long, you have become accustomed to many things, such as diet, speech, manners, customs, and moral values... But there is only one thing that you have not learned how to accurately position yourself. The deviation in self-cognition has caused you to always be stuck in a dead end on the spiritual level..."

At this moment, an elderly but still strong man appeared not far away and picked up the baby in the cradle on the ground.

"The director of the orphanage has changed again!"

"Your remaining life can no longer be given back to you. This is the only way to let you start over again."

When the "Tiger Curse Seal" was stripped off, even Mizuki's blank soul was torn apart. After thinking for a long time, Mizuki decided to make up for it a little.

"Let's go!"

Say goodbye to your past self for the last time, and enter a brand new world.

"I will also consider your suggestion carefully..."
