No matter whether Lan Shangyun is a genius or a madman, at least he has a very deep research on time and space shuttle, which is beyond doubt.

"...The universe was born from the singularity explosion at the beginning, and then the entropy of the universe continued to increase. From cause to effect, this result was the beginning of countless causes, and the entire universe will only change from order to disorder. The heroine of the God of Death came sees the future for unknown reasons and reverses this entropy number, so the entire universe will reject the reversal. The specific manifestation is that she is extremely unlucky, and even at extremes, she will use death as a manifestation."

"Cause and effect..." Yang Yun thought for a long time before asking with difficulty: "But what is the relationship between time and space shuttle and cause and effect in myths and legends?"

"Ha? Are you questioning my research results?" Lan Shangyun said unhappily.

"No, no...I just think it's strange." Yang Yun quickly denied, he vaguely felt that the key to breaking the deadlock...it seemed to be the newcomer.

"That's good." Lan Shangyun cleared his throat with satisfaction and continued: "Everything in the world is connected. Whether it is myths and legends, supernatural stories, or even online novels and horror movies, there is a certain relationship, but we have not discovered it."

"In my opinion, if you want to successfully study space-time shuttle, you must solve the consequences of space-time shuttle. Have you seen the Terminator?"

"Uh... look, I've seen it." Yang Yun said that he really couldn't keep up with this civil science thinking.

"Just see it." Lan Shangyun nodded and said, "The primary premise, or the biggest limitation of time and space shuttle, is that you can only shuttle once at the same time band, because once this shuttle is equivalent to an observer in this band, the time function will collapse into specific data and can no longer be changed."

Yang Yun was almost covered in his head. Is there any relationship between the two? Is the Terminator and the God of Death coming? He really didn't understand, so he had to ask: "Okay... Even if time can really be passed, how can the refutation of time, such as the banana peel theory, and how can we solve the theory of grandmother?"

Compared to the so-called time and space shuttle, Yang Yun is more concerned about the banana peel theory. After all, this is something closely related to their current situation.

"This is what I mentioned before that time is both a wave and a function. You have already understood the theory of function. Once you observe, it collapses. Time is not linear, but wave-like. When we look back at the past, it is actually a history and past made up of countless bands. You can simply think that time is one by one, and each is a time band. When a certain time band is determined, a future that belongs only to this band will be produced. In this way, countless futures will be produced, and the beginning is likely to be the same historical event, such as Genghis Khan, who did not have Mongolia, and France, at that time, there will be no future.

Napoleon was not like Hitler in Germany. In this way, time actually belongs to different parts that can be divided. Each band can be regarded as the future of countless parallel worlds. Changing this band changes countless futures. If you must use simple words to describe it, you can think that when you shuttle back to a band, you have entered a parallel world. If you do nothing, then this world will coincide with our real history. If you do something, a completely different new history will be produced, which can be considered a parallel world." Lan Shangyun said.

“…”

Yang Yun was almost dizzy. God, earth, who will translate what this guy is talking about for me? What does this TM have to do with the parallel world?

"Don't worry, let's get to the point." Lan Shangyun took a sip of tea slowly and said.

"The heroine accidentally saw the 'future' and avoided the destined way of death by the god of death. But is the 'future' she sees a must be the destined 'future'?"

"...what does it mean?" Yang Yun's face turned solemn.

Lan Shangyun slowly showed a fanatical smile and said, "Do you still remember the ending of the second death of the God of Death? The heroine drove into the lake, breaking the death order of the God of Death, and finally temporarily escaped the God of Death with another man... In other words, the 'future' seen by the heroine was changed."

"Thinking in reverse, is it really because the heroine saw the 'future' that the future changed? Why can't it be said that it was because the heroine saw the wrong 'future' and wanted to change it, which triggered the reverse current of time and space?"

"You mean... you have the cause of 'the heroine wants to change the future', and then the result of 'Death Killing'? If the heroine really takes the premonition of death she saw as a joke, then the Death Killing would not have happened at all?" Yang Yun thought of an unprecedented possibility.

"That's right! This is the so-called cause and effect." Lan Shangyun slapped his thigh, "Don't you think it seems that the God of Death killed everyone in order to prevent the future from going to an unknown track, but in fact, the God of Death collapsed into the original one in order to turn the future that had deviated from the track back to the right track?"

"This... this is too incredible." Yang Yun stayed for a long time before he could put up such a sentence with difficulty.

"Don't worry, let's continue to take the video of Terminator as an example." Lan Shangyun laughed a few times and said, "Compared to the present, the time function in the past has collapsed for reality and cannot be changed. For example, the male protagonist of Terminator John Connor, whose future is the leader of the human army. Before that, he has not only experienced hundreds of battles? Is it impossible for a bullet to hit him? Instead of being lucky enough to survive in the most dangerous rain of bullets until he becomes the leader of the human race in the future? This is simply an exaggeration than the protagonist of the novel. But if it can be proved that everything is existing history, then everything can be explained, that is, all futures have long been destined and cannot be changed at all."

"Wait." Yang Yun suddenly thought of something and said quickly: "But if this is the case, a huge contradiction will arise, that is, since the current history has been destined, the future cannot be changed. Since that is the case... Why did the Lord God send us to this world? Why did he propose a task to protect those plot characters? Anyway, the future is destined, and the heroine and another man will not die, and others can't save him, so isn't this task an unnecessary move?"

"Uh..." Lan Shangyun was like a duck stuck in her throat, and her laughter came to an abrupt end.

After a while, the civil science department said sadly: "This... I haven't figured it out yet. If I figure it out, the progress of my time and space machine can take a big step forward..."

Yang Yun's sweat couldn't help but compare the middle finger to Lan Shangyun in his heart.

[This guy can't grasp the key points at all...]
