Time and space are fragile, not unbreakable. But it's also not so fragile and can be easily destroyed.

It is not easy to try to change the established history. You want to snipe the famous people of history to change the course of history. In front of the trajectory of fate, the corrective power of history, it cannot be done. Even mortals who have not done glorious deeds are limited in the changes they can make.

The boundary between life and death, no matter where it is, is a forbidden border. It's not just an attempt to turn death into life. Even the passage from life to death is not as easy as generally thought.

Death to life, life to death. It is difficult for people to come back to life from the dead, and it is easy for everyone to say from life to death. Who knows, life is involuntary.

The "post-choice model" of time travel in which all paradoxical events and paradoxes are forbidden. It allows people to travel back in time and space to the past, but prohibits all actions that could lead to paradoxes in the future. In other words, it avoids the traditional theory that the journey of the time traveler eventually develops into a contradiction with his own existence.

In addition, a new model based on the "post-selection model" is used for experiments using photons. Simulates a peculiar path through time and space: a closed temporal curve. They can carry anything with them back in time and back to the present. It simulates a phenomenon that can be encountered in time travel. As the photon gets closer and closer to the "paradoxical" state, the success rate of the experiment will continue to decrease, which proves that it can prevent the emergence of paradox.

'Emperor's Reward' is hard to find, treacherous and difficult to prevent, but with an undoubted way of grandeur. To put it simply, it is both impossible to dodge and impossible to block.

It is in line with the unfathomability of the emperor's mind and the majesty of the emperor that cannot be disobeyed.

'The whole world is not the king's land, and the shore of the land is not the king's minister.' ’

The artistic conception is open, and it also carries the true character of the emperor, domineering, imperial prestige, emperor, and all beings. There is only one small problem, this artistic conception is not used by Haoqin, it is a person surrounded by black fog.

The black fog gradually dissipated and became thinner, polluting the artistic conception. Yes, pollution. It can be seen that this artistic conception was not constructed with such a dark will, but was formed by erosion later. The black fog that obscures the figure of the person surrounded by the black mist dissipated, but it still made it impossible to see the real person. Because the imposing gaze of the emperor's majesty has taken over as a means of concealing his true face.

However, when Haoqin saw this artistic conception, he withdrew his hand and did not immediately launch a counterattack. His eyes sparkled with thought. However, although it is thinking. But in fact, it has already come to a conclusion.

When the people surrounded by the black mist saw Haoqin's reaction, they did not attack immediately, but stood still in place.

"Daoyi. Hao Qin suddenly took a deep breath and spit out two words.

The person surrounded by the black mist shook his head, as if he was a little helpless, and said, "I still underestimated Master Hao. It stands to reason that you haven't handed over 'my' emperor now, how can you recognize my identity from my moves. ”

Haoqin said: "To recognize is to recognize." If you have to find a reason, there is no definite basis. Dao Yi ......"

People surrounded by black fog, call them the underworld one. Hei Daoyi said: "Master Hao." When you return from that time-travel, you must have discovered it. ”

Hao Qin said: "Originally, I wanted to observe the situation, after all, it is really unbelievable to travel through time and space. However, it was not expected to fall so quickly. ”

Kurochi said: "It's not dead, it's one with 'me'." ”

Haoqin said: "Is that so, I thought it was just that Li Daoyi of this era accepted some memories or something. Was it a fusion? So, you crossed earlier?"

Hei Daoyi said: "I am the current Li Daoyi, and I have traveled to the era of a long time ago in a certain event in the future. ”

Haoqin said: "Is time travel so worthless, it seems to be a rotten street." ”

Kudochi said: "Naturally, it is extremely difficult. But there is no stumbling that cannot be achieved. You think it's incredible, and it's too underestimated...'Providence'. They can control not only the future, but also the past. Hey..."

Haoqin said: "So, what are you crossing repeatedly?"

Hei Daoyi said: "Master Hao, there is a slight problem with your understanding. No, I crossed repeatedly for what. It was very lucky, or unfortunate, that I crossed it repeatedly. If there is one purpose for me, there is only one. Destroy myself. ”

Haoqin said with an expression, "Why?"

The underworld chuckled for a moment and said, "If you don't believe me, too, no one will believe me." If I could do something else, I wouldn't deny myself. ”

Haoqin didn't speak, because the black path had to be explained, otherwise, the absurdity was completely implausible.

Kurodo said: "Although I just said, it is not impossible to travel through time and space. But in fact, it's never easy. This kind of thing, there will be many problems. Say, paradoxes. For example, if I go back in time and kill my grandmother before she conceived my mother, would I still exist? If there was no my grandmother there would be no mother, if there was no mother without me, how could I "go back in time" and kill my own grandmother before my grandmother conceived my mother. ”

Haoqin said: "Is it a parallel world, every thing that distorts time creates a new parallel world. ”

Hei Daoyi said: "Master Hao, he is worthy of being among the top people in the world. ”

"I once met a very interesting young man and got a lot of new knowledge from him. And the 'space plan' has a lot to gain. ”

Kurodo said: "Although, that is indeed a possibility. Moreover, the fact that you have found a similar world adds to the evidence. But, in my experience. Embracing another possibility. ”

"Every world is unique, and the number of worlds that exist is very small. Time travel is to travel on the original line. Theoretically, you can change history. ”

"But in fact, you can't change anything. The world has the power to correct, and even your existence is the object of correction. ”

Without waiting for Hochin to speak, Kurodo continued: "Think of the concept of time as a river that flows endlessly. In one of the nodes is now. The future is a myriad of tributaries with infinite futures, and the past has converged into a backbone, representing the general trend crushing the future. And in some special places, there will be backflow, which has never caused time and space travel. ”

"Master Hao, do you really feel that you are living in the present? Hasn't everything now become history?"

Haoqin said: "You said that everything has become an established history, so it is also history when you see me this time? So, at the beginning, in the era that you did not cross, who replaced you who crossed and completed the role of history. ”

Hei Daoyi said: "It's very simple, that is, in a moment, the great river of time flows back, causing me to cross. It was Li Daoyi who returned from the future before. This is not a paradox, not an end-to-end ring, and it does not need to be explained in an incomprehensible beginning. I've got it, it's simple. You just need to understand that the node that represents the 'now' is 'absolute'. Even if it returns because of the river of time. The person who crossed over is carrying the present node, and what he does is not modification, but creation. It's like you draw a line and you return with a heavy stroke. That stroke is an increase, an exact presence. ”

"To put it more simply, as soon as the original Li Dao returned, he created history, he could do anything, he could kill anyone, kill the future emperor, kill the future strong, and kill the past self. He can kill his maternal grandmother without the paradox of time and space. ”

"If he killed his maternal grandmother, his mother would not have been born." Well, he will not be born either. Or, you mean that Long Aotian can become Zhu Aotian and Gu Aotian. Will he be born through someone else?"

Hei Daoyi said: "What I said is so incomprehensible, it seems to be a little." So let's be more careful. First of all, he was born until before the crossing, which is history. He went back in time and killed himself, and this became history. Then he will not be born. Then the world evolved into what it was without him. This is history. And then the length of the whole history, is the sum of those histories. The history that disappeared did not really disappear and constituted the length of absolute history. But the history formed after its return covers part of the history, which constitutes the relative length of history. ”

"So, what if he returns? When he returns to the future, what will the future become? Is it the world before he travels, or the world he has changed." If it is a line, it must be a changed world, and if it is a changed world, where will he go?"

"I don't know. Kudochi gave this answer unexpectedly, "Is it easy to travel through time and space? Can you wear it around? I don't know that." ”

Haoqin said: "Wait, these, put them aside. What exactly is your purpose, what exactly is your purpose?"

Kurodo said: "Change a given future." ”

Haoqin said, "Can't you change?"

The underworld was a little crying and laughing, and said: "I just explained that this is the 'now' node, and no matter what you do, it will form history. However, outside of the 'now' node. You can't change it. History cannot change history, only the present. ”

"You just asked me if I'm really living in the moment. So, you mean, it's history now?"

The underworld nodded and said, "Yes, I'm history too." Either I represent the 'now' me, but I have returned to this era, and I can't do anything different. I can't kill anyone except... I can't change anything, it's hard to... This is history, and so am I. I'm not the present, unable to create a new future. All I can do is follow my fait accompli. Towards a doomed end. However, I would like to see if I can change it. ”

Haoqin didn't speak, waiting for the underworld to continue.

"I can only be like a wandering ghost, hidden in the shadows. We can only watch the world go into ruin and cannot reverse it. ”

"I understand something. The future, is it bad?"

Kurodo said, "It's bad. ”

"There's one more thing I want to know. One inadvertent move can have consequences for the future. ”

If a bad and small mechanism is not guided and adjusted in a timely manner, it will bring great harm to society; a good and small mechanism, as long as it is correctly guided, will produce a sensational effect, or be called a "revolution", after a period of hard work.

Heidaoyi said: "Even if I subjectively want to change, it is difficult to change, not to mention the impact of the unconscious." In the face of the power of correction, there is no point. ”

"You don't know everything, and you can't change what you define that goes beyond what you remember," Hochin said. ”

The underworld laughed, but he was by no means happy: "I know what is the correct history. Because when I get it wrong, I feel a huge obstacle. And as long as it's the right history, the repulsion I feel can barely hold on. ”

Hochin finally said, "Just, you can't make a change. So, what's the point of your existence?"

Kurodo said, "I can't change it. But there are others who are part of this history. Haoshi, believe me, I have been thinking about it for almost a thousand years. I'm ready. ”

"I know what you're going to do. You said you could barely kill anyone. The exception is you. But, I don't understand, you've said a lot about it before, and you've already said that. ”

Kudochi said, "I can't kill anyone." I'm not at the 'now' point, and I can't kill myself, which creates a paradox and I'm going to disappear before that happens. Or, with the help of Providence, I may be able to make things happen. Not really, though. I can't kill myself, but I can deny myself. Haoshi, I actually vaguely touched this concept just now. ”

"How can a person be sure that he is who he is, whether it is body or soul, emotion or past experience? Long Aotian was killed before he was born, so maybe there will be a living dog Aotian to replace him. But this Zhu Aotian is alive, and the dog is proud of the ground, isn't he?"

"A person is unique because he is who he is. His body, his soul, his emotions, his past experiences. All these things constitute a sense of existence. If a person's sense of existence is replaced by someone else, or it is 'him'. ”

Haochin asked, "You've already decided to deny yourself. ”

Kurodo nodded and said, "Yes, but until now." Because there are still some arrangements that have been delayed until now. Without some preparation, the striking similarities of history will only repeat themselves. ”
