It was still the spiritual world full of memory bubbles. The strange red and black aura had already penetrated everywhere. The red light on Yuan Shuimu's body opposite him made it impossible to see his original appearance. Through the red light, red lines could be vaguely seen all over his body.

"It looks like it's almost over. Hara Mizuki can't hold out for much longer."

Shui Mu silently mobilized his mental power and stretched out his hands. The originally dim magic circle gradually emitted a dazzling green light, forming a thin light film that wrapped the red figure and isolated most of the red fog.

"If I hadn't used this Four Symbols Seal, I would have been eroded by the surging mutated fairy chakra and lost my self-consciousness. It's a pity that I haven't mastered the higher level of the Eight Diagrams Seal, otherwise I would have an extra huge chakra source in my body."

After first realizing the mental hidden dangers in his body, Shuimu made a detailed analysis of his own mental state, and the analysis of self-consciousness was the top priority. Although it can be simply summarized as time travel or possession of another's body, the truth is far from that simple.

As for the concepts of self, id and superego mentioned in Freud's theory, it is too exaggerated and does not fit the current situation. However, this statement is only a difference in spiritual realm. The key is to identify oneself and others. There is no doubt that I have memories of my past life, but I am still unclear about how my spirit travels through time. Whether there is another self to complete my ordinary life on my behalf, and I am just a collection of memories traveling through time is still unknown. However, it does not matter. The past life has left me, and I am Shuimu in this life. There is no doubt about this. The key is the guy opposite.

In the original intention, with the willpower of a greenhouse flower born in peacetime, it is hard to believe that I can take over the body of the original Mizuki, a ninja born in war and with a strong will and paranoid. With superior willpower and strength, and the main body fighting at home, how could it be defeated so easily? But the reality has already happened, so there must be a reason. In terms of the characteristic of soul penetration, there is no doubt that I am far inferior in quality, but the key to the turnaround lies in the huge gap in quantity. With Mizuki's experience of less than 30 years, how can it be comparable to the amount of information generated by the advanced Internet technology and knowledge explosion in the previous life. It's like a hacker invasion. No matter how powerful the computing power is, it will crash instantly when it encounters a tidal attack that far exceeds the ability to bear.

In the battle of spirits, the winner takes everything. And there is no such thing as two souls existing in one body without reason. There is no doubt that Shuimu is dead, as I can tell from everything I have obtained from Shuimu. The guy on the other side is just the remnant of a soul that has lost everything. If nothing unexpected happens, Shuimu will remain silent or slowly disappear until his death.

In terms of philosophical concepts. What is memory? Plato believed that it is memory and knowledge, and of course some people believe that memory is the soul. But no matter what, memory is the essence and the basis of self-cognition. This will not change. These are all subjective things. I am equal to memory, which fits the current situation. Since the failure of Yuan Shuimu, I am Shuimu. Yuan Shuimu has lost the basis of self-cognition. In terms of existence, he is no different from a roadside stone. The difference is that one exists in the real world and the other exists in the soul of the self.

That was how it should have been, but because of the curse, everything changed.

The curse seal is the result of Orochimaru's research on Sage Mode and Reincarnation, and has a dual corrosive effect on the body and mind. The damage to the body caused by the Heaven's Curse Seal, the Earth's Curse Seal, and his own Curse Seal is obvious, but his unfinished product is more serious.

In terms of mental erosion, the erosion of the Heaven and Earth Curse Seals was carried out through Orochimaru's soul backup, in order to prepare for the transformation container. The own curse seals saved this step, but the mental erosion was replaced by mutated fairy chakra. In other words, it was the unconscious erosion and assimilation of the entire world. Although not as targeted as Orochimaru's soul backup, it was more troublesome.

Fortunately, I didn't travel through time when Orochimaru gave the seal, and the main body of the seal is still on Hara Mizuki's soul. The reflection in the spiritual world is that the erosion on the other side is far more serious than on my side. In addition, the sealing technique I cast not long ago has greatly reduced the erosion of my spirit. Even so, it is already very serious.

Actually, although my curse seal is incomplete, it may react to natural energy and fairy chakra. But it should not reach this level. I should blame myself. The original Mizuki was taken over by me, and I lost my memory and self, and of course I also lost my soul's instinctive defense. Both my mind and body defenses were opened, and I couldn't resist at all. In addition, after being stimulated by the same source power of Mitarashi Anko, it was like firewood meeting fireworks, and it was completely unstoppable after being ignited. In less than a month, the opponent was almost completely finished. It is estimated that it will be completely annihilated soon.

"In other words, if there is a collective unconscious in the world, it might become something like a heroic spirit or a world agent. That would not be fun."

I stretched out my hand and quietly felt the red breath, but it seemed that I could feel nothing.

"No malice, although it looks weird, but is it just an aesthetic issue? Or is it that the world actually has no malice, but is it just the result of instinct and indifference~"

"Hmm? No, as the master of the spiritual world, the change in color reflects the subconscious vigilance. Red is a warning, black is a threat. Is it just the instinct of the world that makes you exhausted? I have to hurry up."

…

Early in the morning, Shuimu was awakened by the sound of birds.

"The early bird catches the worm."

Shuimu woke up and first checked his precious jellyfish, then looked at the rare plant samples. Everything was normal. Then he walked into the bathroom and took a shower.

Looking at my appearance in the dressing mirror, I can see that quite a bit of changes have taken place.

"My hair grows too fast. My silver hair has already gone past my shoulders. I've already cut my bangs once, but they're almost covering my eyes. And~"

Mizuki rubbed his temple. "My health is getting worse."

With the soul residue of the original water and wood as a big sieve, the invasion of natural energy is endless. The damage to the spirit caused by the curse is temporarily controlled by the Four Symbols Seal, but the consumption of the body is too great. The seal of sealing evil must be prepared as soon as possible, but how can the seal be completed without being monitored? We need to think of a way~

…

After finally getting ready, Shuimu went out. Since receiving the order from the third generation, he went to get off work and came home on time every day just like in his previous life, and relived the feeling of being a white-collar worker from nine to five.

However, Shuimu, whose health was getting worse and worse, would always take time to replenish his physical strength. The body produced a lot of energy at an extremely fast metabolic rate, but it was dissipated meaninglessly, causing great physical deficits.

"Ah, isn't this the pervert teacher?"

"Which bastard is so rude? Aren't you afraid of being upset when you wake up by disturbing other people's sleep?" Shuimu opened his eyes and looked at him unhappily.

"Hey, isn't this Tiantian? Have you completed the mission? Oh, Teacher Kai, sorry for the rudeness." Mizuki took the mission report and confirmed that it was completed.

"Thank you for taking care of my disciple last time, Mizuki." Might Guy said cheerfully.

"You're too kind. Your students are excellent. Even a Chunin like me feels very stressed. Haha."

"That's all youth." With the thumb up and the shining teeth, he looks like a passionate teacher.

"Haha." Mizuki laughed awkwardly. Then he arranged a C-rank mission for the Genin according to Might Guy's instructions and left.

"Oh, it's really leisurely."

"That's right, Shuimu." Someone next to him said.

"Hmm? Iruka, when did you get here? Your ability to conceal your aura has improved a lot."

"You are too lazy. If you fall asleep at work, be careful about your salary being deducted." Iruka teased.

"There's no salary anyway." Shuimu muttered. Three months' salary had already been deducted.

"Shui Mu, here is a commission. Take a look. If there is no problem, it will be ranked C-level."

"Well, let me see."

After taking the task application, Shuimu took a glance at it, and his absent-minded mind was swept away.

"Nation of Waves? So soon?"

Maybe Mizuki was wrong. This mission was the most important dungeon for the protagonist team before the Chunin Exam, and it took much longer than expected. It would take more than a day or two for a few old men to build a bridge with the current productivity. It didn't seem strange to entrust the mission at this time.

“But is it profitable?”

After thinking for a while, Mizuki said to Iruka: "Wait for this for a moment, I will go and ask for instructions first."

"Eh? It's an ordinary escort and protection mission. The opponents are most likely ordinary people like bandits or robbers. What's wrong with that?"

"It's hard to say. It's better to be cautious."

After saying that Mizuki stood up and walked towards the Hokage's office.

Arriving at the door of the Hokage's office, Mizuki knocked.

"Come in."

Shuimu pushed the door open and went in.

"Third generation sir."

"It's Mizuki? What's the matter?"

"I just received a mission commission, and I think there is something wrong."

"Um?"

The Sandai picked up the report presented by Mizuki and took a look at it.

"The mission description is very simple. According to the mission client, it is more appropriate to position it at C-level. Do you have any questions?"

"Sir, I think I need to do some research on the details of the mission."

"investigation?"

"Yes." Shuimu confirmed, "I once went on a mission and passed through the Land of Waves. It was poor and ignorant, and some local forces occupied it and exploited the villagers."

"Are you doubting that they won't have the money to pay the reward? No one would dare to default on the commissions owed to Konoha ninjas."

"No, Hokage-sama, I suspect the client lied about the mission level." Mizuki paused and said, "For something like building a bridge, it is definitely not a small matter. It involves the interests of too many people. It is hard to guarantee that someone will take the risk."

"Hmm." The Sandaime thought for a moment and said, "What you said makes sense, but it's not appropriate to investigate the client before the mission begins. Also, Konoha is short of manpower and can't go all the way to Wave Country. Let's leave it at that for now. I'll arrange for the right people to complete the mission."

"I know. Sorry for bothering you."

After saying that, Shuimu walked out.

"The inertia of history is too great. Without strong power and influence, it is very difficult to make changes. But it is not without benefits. If you make your presence known, you may get unexpected gains."

"However, the demon Zabuza and Haku are not people I can deal with right now, and my body is not in good condition yet. I have to complete the seal to seal evil first!"
