Eight things in life are unsatisfactory nine times out of ten. If you had the opportunity to go back in time and change all the things that made you sad, would you be tempted?

Ninety-nine percent of the people will be tempted by this opportunity.

But when you travel back in time and space, can you really change to history? This question, many people will think, of course it is possible, back to the past, that is equivalent to having an extremely powerful plug-in, how can it not work?

Unless it's a waste, he's just going back in time and still a waste.

But Li Yu will tell you, boy! Think too much!

"It's not easy to change the past. Because the greater the difference from the history that has already occurred, the more counter-energy its behavior will generate, and the more difficult it will be to change. ”

"I'll take myself as an example. If I go back in time and want to change the outcome of that event that affected my life, guess what? ”

Heard that Li Yu actually used that incident as an example? Fang Qianmo's heart was stunned, Li Yu really let go completely!

"How will things turn out? You went back to that point in time, didn't you exist then? Lin Wanbai was puzzled.

"Well, I must have existed at the beginning, and I definitely won't be able to find out who I am now, unless I show up on my own."

This is interesting, with Li Yu's strength, it is easy to prevent a traffic accident caused by drunkenness. It's just that after the traffic accident is prevented, how will things develop?

Xiao Li Yu will not lose his parents, so will he become an unprecedented scientist like now? It is very likely that Xiao Li Yu will only become a famous scientist, and because of his outstanding achievements, he will be absorbed by a top-secret research base in China.

And then what? Xiao Li Yu, who didn't get the space rune, wouldn't let the earth enter the interstellar era so early, and it was impossible for Xiao Li Yu to know Fang Qianmo, and Lin Wanbai's fate couldn't be changed.

Maggie, Sun Yixuan, Anna, everyone in the laboratory may not know each other, and they will not be able to get together.

Green and the others can only move forward in confusion, and they can't find a solution to Roland's problem. Tribal civilization will also wreak havoc in that heavenly region, and no one can control it.

In this way, the traces of the existence of the laboratory in the universe will eventually be gone? How strong should such a historical change be? This is not a small change on Earth, it can be said that it involves the historical changes of several heavenly regions.

That's what everyone in the lab thinks.

How will history develop?

"Li Yu in the past may never know us again, but I think you will definitely gather us again!" Fang Qianmo's expression was very complicated, and Li Yu's assumption really made her think a lot.

"You're going to stop me, aren't you?" Lin Wanbai also thought of the moment when her fate changed.

"Huh! You're thinking a little too much! If I take action to change the outcome of that accident, you will definitely not be able to do it, and the moment I make a move, I will immediately face the irresistible counter-energy generated by the universe in an instant, sending me back to the moment before I traveled through time and space! I can't do anything! ”

"It's not just me, it's Wanbai, I can look at you from afar, and I can get to know you again, but if I want to change the fate of your parents, the moment I make a move, I will still be sent back by the anti-energy."

Li Yu's answer was beyond Fang Qianmo's expectations, Li Yu couldn't change his fate?

"That's what you just said, that all the problems come down to energy? Because your current strength is so powerful, even if you remove your identity as a mage, your great achievements in science and technology, any change you make to your past self will require extremely powerful energy. ”

"Especially for events involving key points, as long as you make a move, it will touch the defense mechanism of the universe itself, and the counter-energy generated will not be neutralized at all, and although Pang is there, it can only send you back to the present."

"Li Yu, is this the sorrow of the strong, or is it our luck?"

Fang Qianmo didn't know why, after listening to Li Yu's explanation, she was inexplicably relieved in her heart, and felt that Li Yu's decision not to rashly conduct time and space travel research was really too wise.

"Li Yu, I have a question, if an earthling goes back to the past and changes history. Can we detect it now? Sun Yixuan suddenly had an idea in her heart, so she immediately asked Li Yu.

After joining the laboratory, Sun Yixuan's feelings for Li Yu are very complicated.

Although she once said that the past is like smoke, let the past pass. It's just that there is such a thing as feelings, especially first love, and it's a secret love that hasn't had time to confess, it's really so easy to forget?

Even if Sun Yixuan now regards Li Yu as a friend, a very good friend, and a like-minded seeker, Li Yu is different from others.

Now, Sun Yixuan thought about what if someone went back to the past and changed the process of her acquaintance with Li Yu, and the phone didn't fall?

"Detect space-time fluctuations caused by space-time travel? If it's about us, there's no problem with that. If someone goes back in time and what he does involves us, then there will be abnormal space-time fluctuations around us. ”

"Analyzing the spatio-temporal fluctuations of this anomaly, we can even locate the time period that caused the spatio-temporal anomaly, and with a little more effort, we can locate the existence that caused the spatio-temporal anomaly."

Sun Yixuan's question, Li Yu thought about it for a while, and felt that there was no problem, but as soon as his voice fell, not only Fang Qianmo, but also Lin Wanbai and Sun Yixuan, all their eyes lit up.

"Li Yu, it's necessary for us to set up a space-time administration!" Lin Wanbai's face was very serious.

Well!? Why is it so serious all of a sudden? Li Yu felt a little sudden.

Li Yu didn't understand why other people reacted so much, it was because he didn't know that he was not just a friend to the members of the laboratory.

It can be said that Li Yu's existence has changed the fate of every member of the laboratory, and they can't imagine what a terrible thing it would be if they didn't know Li Yu and didn't belong to the laboratory anymore.

Therefore, on the idea of establishing a space-time management bureau, Fang Qianmo and the others achieved a high degree of unanimity.

"Huh!? It's good if you're happy, the Temporal Authority, it's good if you're happy! ”

Isn't it just the establishment of a high-ranking organization, what is this, established! Li Yu thought, but do you have time to manage this organization? Is it difficult to throw it to Cheng Yingnan again? I really want to use Cheng Yingnan to death, but she has wanted to explore the universe together for a long time.

If another space-time management bureau is established, it is foreseeable that the time when Cheng Yingnan leaves the deep-sea base will be a distant matter.

"Li Yu, you must attach great importance to this matter. By the way, I have another question, can we also be affected by the space-time anomalies that occur on the other side of the Earth in this celestial region? Fang Qianmo wanted to confirm this.

"A must! Our bond with the Earth is much deeper than you think. ”

"The role of space-time is only in three-dimensional space, it is a high-dimensional space, no matter where we are in this universe, we can detect the changes that have occurred in the past of the earth!"

With Li Yu's words, everyone was relieved.

"Well, I have to say hello to Cheng Yingnan and ask her to set up the organizational structure of the Time and Space Administration Bureau first." Lin Wanbai thought further.

If a space-time anomaly occurs on this side of the earth, and the laboratory is far away in the heavenly area where I don't know what the hell is, then the task of dealing with the space-time anomaly can only be handed over to Cheng Yingnan who is on the earth.

Regarding the question of how the Time and Space Administration should operate, this can be discussed with Cheng Yingnan next time when I return to Earth, and now we will set up the shelf first.
