Zhou Qingyu read the letter and felt that this was the most ridiculous thing he had ever seen, he sat in a daze, and it took a long time to return to his normal thinking.

Zhou Qingyu looked at Xu Guohua and shook the letter in his hand, "Just rely on these two pages to make me believe you?" ”

Xu Guohua spread his hands regretfully: "At present, our research is still in its infancy, and I can't give you more evidence!" ”

Zhou Qingyu still felt incredible: "Which space are you Xu Guohua?" How did you get this letter? ”

Xu Guohua smiled at him soothingly: "Before answering your question, I want to explain the time to you." We often say that time is like water, and there is truth to this saying! ”

"It speaks to one of the most important properties of time, which is that the cycle goes on and on. In other words, as long as the speed is fast enough, time can be reversed! ”

Xu Guohua said this sentence firmly, and then drank the tea in the cup, and then continued to explain to Zhou Qingyu, "Every time and space seems to be unrelated, but in fact, they are cause and effect of each other. In other words, your result in this plane may be the beginning of the next plane! ”

"Let me explain it to you like this, Zhou Qingyu, who wrote to you, in order to reincarnate Su Keke, use energy to send her to this time and space, and he will become your cause."

"What is mutual cause and effect? What do you mean by fruit? Zhou Qingyu didn't understand what Xu Guohua meant at all.

"This fruit, for you, is your wife Su Keke! Su Keke was originally going to die, but you used the space-time machine to teleport her back here and marry her, this is the fruit! Xu Guohua saw that Zhou Qingyu still didn't understand, so he simply concretized all the characters and events.

"This letter makes it very clear that you want to help us build a time machine. If you don't have a time machine, then nothing you do! Xu Guohua became serious, "Because, from the principle of the cycle of space-time order, this space-time has a time machine, which is a necessary condition for you to transmit, that is, the cause!" ”

Zhou Qingyu asked rhetorically: "You mean that if there is no time machine, then, I will not marry Coco as a wife?" ”

"Yes, there is no cause and no effect, if you don't operate in another time and space, then, you can't marry Su Keke!" Xu Guohua replied in the affirmative.

Zhou Qingyu was very surprised by such an answer, but when he thought about it, Su Keke's situation when he identified Emperor Ge was very strange.

To explain it with Xu Guohua's theory, it is very simple, Su Keke had seen Emperor Ge before coming to this time and space, so she recognized Emperor Ge at the first time.

At that time, Su Keke herself could not explain this phenomenon, so she put it all down to a dream.

Zhou Qingyu reasoned about Su Keke's abnormal behavior and came to a conclusion, although Xu Guohua's statement is absurd, it should be true!

"So, can you answer me now?" Zhou Qingyu still wanted to continue to probe, "How did you get this letter?" ”

Xu Guohua didn't care about his stubbornness, and nodded with a smile: "What's the hurry?" You gave me this letter! Of course, you don't know about it now! ”

"When you build a time machine, you'll understand the whole thing!"

Zhou Qingyu asked rhetorically: "You want to build a space-time machine, why do you want me to help?" There are a lot of powerful people in this country! ”
