Zhong Jianbai held his head and put his fingers in his hair. After a long time, he raised his head again. He looked at the screen, then frowned: "Zhao Mai, when did you know you could travel to other worlds? Can I say within two years or two years ago without telling me the specific date? "


    Because he wanted to get rid of the time difference and just calculate the time of the earth, Zhao Mai replied, "in two years, what''s the matter?"


    "That''s the trouble." Zhong Jianbai said: "the old man will look back on the incident and eliminate the influence. If the time goes back two years ago, what happened from that point may not be the same as it is now. That is to say, you may no longer be able to acquire this magical ability. It''s not very likely, but it does exist. "


    "If I go to other worlds, can I avoid it?"


    "I don''t know." Zhong Jianbai replied: "except for the detachment and a few passers-by, others will be traced back. Ordinary people will not be greatly affected because of their low energy level. For example, your parents and family will no longer be affected by memory erasure. The basic track is still not far behind the present, but you are not sure. I''ll get in touch with the old man right now. I''ll make sure to ask him clearly. "


    Zhao Mai thinks more. The old man told him more than once that he should "have a good rest and have something important to do when he comes back". Is it related to this? If the detachment is really beyond time, then what is happening now is not expected? Why let it happen? Is there some kind of script between the earth and other worlds, like atas or Westeros?


    Is he just another Jon Snow or Karak, whose fate has already been determined? A sense of fear came to me. I still remember the joy when the old man congratulated himself on taking the "first step". Now it may not be so simple. Zhao Mai with a complex mood waiting, as if waiting for a sentence, every minute and every second seems to have become suffering.


    All the text on the screen disappeared, leaving only a decreasing number. "This is the normal living population on earth," Zhong explained. "This number can reflect the seriousness of every event. I just saw this in the record. It''s my first experience. "


    "If you can''t remember all this in retrospect, how do you know?"


    "The old man always leaves a detailed record to let us know what happened and what went wrong." Zhong Jianbai sighed: "the last global retrospection was the Cuban missile crisis. The global nuclear war and destruction has happened, but it has been reset. The number of that time is 633, and this time is 634. "


    "So many times?"


    "Yes. I know you have doubts in your heart, and I did the same for the first time. But you must remember one thing: don''t rush to make a conclusion. You must look and think more. Many things can only be solved by time, and a small part of them can''t even be solved by time. "


    "I understand that this time it''s the wizarding world. It''s become like this. I can understand the time going back. But why not stop it in advance, and it also affects people''s memory? Isn''t the detached person very opposed to this kind of thing? "


    "I''ll explain it to you." The old man appeared in the room out of thin air. He nodded to Zhong Jianbai, indicating that he could stay and listen in. "We have reached a consensus that even if we foresee a disaster, we can''t stop it by our own will. Each of us will see too many possibilities that exist and occur simultaneously in countless worlds, which is the basis of diversity, real vitality and the existence of the universe. We detached people also observe and learn in this diversity. If we change all the formulas in the world to 1 = 1 according to our own ideas, where can we get 1 + 1? "


    "So you let it happen?"


    "We constantly learn from our mistakes, stay and teach. We don''t interfere in listening or not, learning or not, doing or not. And I can go back and give people a chance to come back. " The old man said, "it''s tiring, but it''s necessary. Progress is certainly a good thing, but mistakes are also precious. We can''t think that mistakes are necessarily bad. "


    "But those memories?"


    "I''m not the only one who can reverse time, but I''m the only one who can make sure nothing goes wrong. And it''s not about memory, it''s about potential. " The old man stroked his beard and said, "what we value is human intelligence, creativity and development potential. In particular, there are some detached people whose earliest state is human. Naturally, they are very emotional. We all agree that we should not affect the future development of mankind. This is the highest criterion. "


    "If we say that the knowledge of the universe is a piece of white paper, our detachment is an ink dot on it. It keeps spreading and expanding, but it''s getting slower and slower. If there is no new supplement, we will stop developing. For us, no change means extinction. " The old man said, "we allow mistakes, because that''s change. But we must correct those things that seriously affect the next change. This is the case with the forgetful spell in the wizarding world. "


    "Now I understand what you''re doing." Zhao Mai nodded, "thank you for telling me these things. I don''t think it''s necessary for me to know these things if I''m also in the scope of time tracing, right? After all, as long as I look back, I don''t know what happened, unless I go to Zhong Jianbai to read the information. So the final question is, "what do I need to do next?""I need you to go back and keep something for me as insurance against accidents." The old man said: "this time the voting is very strange. Something happened that I didn''t expect. On the one hand, I''m very interested, on the other hand, I have to be careful. "


    "Based on the results of the vote, I will go back to the world two years ago. But there will actually be eight people going back to an earlier time, 1995. The earth will be protected, and the wizarding world will not. These eight people will compete separately to change the development track of the wizarding world, so as to determine the future belonging of the wizarding world. "


    The old man said it lightly, but there was a huge wave in Zhao Mai''s heart: "this means that I am one of these eight people? Time travel? "


    "No, you are the ninth, and your role is not to compete. You have another task. On the one hand, you have to go back and live until now. On the other hand, you can see if you can do something to prevent the wizard world from happening again The old man said: "at this stage, you can never come back to China, nor can you contact the relevant ministries, let alone disclose the relationship between you and the relevant ministries. You need to change your name and spend this time in a foreign country as an insurance measure to protect the present and even me. You can rest assured that you and the people around you will have enough youth and longevity. "


    "I don''t understand. Why me?"


    "First of all, you can grab other people''s crossing plans, so that you don''t have to be one of the eight people, but also have the necessary conditions to go back. And you''ve taken the first step and are the only one in your multiverse. When time goes back, people like you have to avoid yourself. For example, when time goes back half a day ago, two of you appear on the return train at the same time, doesn''t it contradict the point that "you are the only one"? So, without your consent, you will not be traced back. You are the best person to keep the current state of the world. But you can''t take the initiative to find yourself and deliberately create conflicts, at least not until you grasp the power of time. You can hurt yourself and seriously affect your potential. "


    "Do I have another choice?"


    "Yes." The old man said, "you can go now, go to any other world, and avoid backtracking. But then, from your family''s point of view, these two years will be different, and now everything they get will definitely change. You may even have to face a history that you are missing for two years, which may be a new timeline. The safest way is for you to go back to the earlier time and reinforce but not affect this period of history, just as we detached people always go back to the earliest time to reinforce our own existence. My advice is that you have to travel at least once to know what the hell time is


    Zhao Mai snorted heavily from his nose: "in fact, I don''t have a choice, do I?"


    "No, you do have a choice." The old man said, "you don''t understand now. It''s nothing. But at least you''ve taken the first step. You can watch the development of things and have the potential to figure it out. "
