After a burst of laughter, Yang Dong finally remembered that Li Yi seemed to have something to say to her.

She paused and asked, "By the way, what did you just want to tell me?" Yang Dong, who told the secret in his heart, finally became a little more lively.

"What did you say?" Li Yi deliberately delayed time, and then replied with a smile with a teasing expression, "I didn't seem to want to say anything just now." Well, let me think about it, what am I trying to say, right! I would like to say ......"

Speaking of this, Li Yi's tone was lengthened again, and Yang Dong even had an urge to pinch him.

Li Yi put on a mysterious smile and said to Yang Dong: "Actually, your brother and I ...... It's not a person from this world. ”

Yang Dong naturally didn't believe it, in her memory, Li Yi grew up with her, and her IQ may not even be as good as her, how could she be an alien?

Li Yi naturally saw the suspicion in Yang Dong's heart, he thought for a while, and then said to Yang Dong: "Hold my hand." ”

Yang Dong wondered why he made this request, but he still stretched out his hand suspiciously: "What do you want to do?" She was a little strange about Li Yi's performance today.

"Close your eyes, be silent for a few seconds, and then open them again."

Li Yi's voice suddenly seemed to come from a long distance, and his voice was erratic. "Like...... It seems to be in ......" Yang Dong thought carefully, "That's right, it seems to be in space!" ”

Yang Dong suddenly opened her eyes, and everything in front of her made her unable to calm down.

A huge planet appeared in front of me, and it was Earth!

Yang Dong suddenly remembered a photo of an astronaut looking at the earth in space, and now she is like the astronaut, standing in the far and near space, looking at her mother earth.

After a long time, it seemed that he had memorized the appearance of the earth in his heart, and Yang Dong calmed down and looked around excitedly.

Li Yi was standing on her side, with the gray ground under her feet.

"Here it is...... Moon? Yang Dong's heart was incredulous, she felt as if she was in a dream.

Li Yi nodded: "That's right, this is the moon, the real moon, and besides, you're not dreaming." If you don't believe me, you can pinch yourself and try it...... Hiss...... Hiss ......"

He suddenly gasped and interrupted himself.

Li Yi looked at the red mark on his arm, and said helplessly to Yang Dong: "You can pinch yourself, why pinch me?" In his memory, Yang Dong had never been so lively.

Yang Dong didn't pay attention to Li Yi's words, but looked at him straight and didn't say a word. It can be seen that although she looks much better now, her face is still a little pale, and she seems to have little nostalgia for the world.

Li Yi looked at Yang Dong's appearance and couldn't help but feel distressed and said, "Do you think physics doesn't exist anymore?" ”

At this time, Ye Wenjie didn't know about the three-body problem sending out Zhizi, and Evans didn't tell her. Therefore, Yang Dong did not know that the particle collision experiment on the earth was due to the interference of two wise sons sent by the three-body problem. As a result, she fell into a dead end where physics did not exist, and she needed someone to help her.

"Didn't you even listen to me when you were at home?"

"Aha, what did you say? You seem to have said something about the chaotic results of the particle collision experiment......" Li Yi's voice became lower and lower.

Yang Dong sighed: "Forget it, I'll say it again." Since 2005, the world's three particle collision laboratories have not succeeded in experiments for unknown reasons, and even the previously verified experiments have failed. Do you know what that means? ”

Li Yi replied: "It means that your cutting-edge physics research will lose its path." ”

"That's right, there is no law in the experimental results, the cutting-edge research of physics will stagnate, and the road of basic physics will be suddenly cut off, which means that it is impossible for human beings to come into contact with the truth of the universe." Yang Dong's emotions became excited.

"So?" Li Yi knew that Yang Dong wanted to vent the depression in his heart, so he was also patiently guiding.

"This means that human theoretical physics will not advance in the slightest, and in a few hundred years, these people today will be able to tell even the most cutting-edge parts of physics, can you imagine? Can you? Yang Dong's voice already had a crying tone.

Li Yi noticed that her eyes were already red. The inability to progress in physics and the fact that her mother is a sinner of mankind are two things that smashed into Yang Dong's heart like a giant hammer, and it is precisely because of this that she embarked on the path of liberation.

But now, Li Yi is here, and he naturally won't watch Yang Dong walk towards the ending in the original book.

He put his shoulder close to Yang Dong: "If you want to cry, cry out, I can contribute my shoulder." ”

Yang Dong could no longer stop the tears in her eyes, and the crystal teardrops fell from her eyes that seemed to be a hidden spring, because of the low gravity on the moon, her teardrops had the special effect of falling from a high altitude to slow down.

Teardrops fell on the surface of the moon, shattered, splashed......

After crying for a long time, Yang Dong finally stopped sobbing, she looked at Li Yi, her eyes were full of anticipation: "Is there any way you can restore the earth to its original state?" She looked at the loved one in front of her, who had grown up with her.

"I'm sorry, but I don't have anything I can do right now. I have to wait, I need to wait until that thing comes out on its own. Li Yi spread his hands, and said helplessly, with his current ability, he can probably only work on Zhizi when he shows the flickering of the universe.

And this moment is not far away.

The plot in "Once Upon a Time on Earth" is about to begin.

Wang Miao, Ding Yi, Shi Qiang...... These people will shine one by one, and the era of crisis will also begin.

Li Yi invited Yang Dong: "So, are you willing to come with me to discover the mystery behind all this?" ”

Yang Dong didn't speak, just nodded firmly.

At this moment, the sun on the moon has risen, and the dividing line is exactly where they are, with light on one side and darkness on the other. Between the two-level divided world, the figures of Yang Dong and Li Yi disappeared again.

A few days later, Wang Miao's house.

Shi Qiang and Wang Miao's first meeting was not pleasant, Wang Miao was like most scientists at this time, they studied science, and they didn't want to be too involved in other things; Shi Qiang is different, as a soldier-turned-police officer, his knowledge may not be high, but he has been fighting wits and courage with criminals by unscrupulous means all year round, and he has also honed his great wisdom.

Therefore, he is also one of the most brilliant people in "The Three-Body Problem".
