Bai Yang turned his head and looked at the three people standing behind him.

Wang Ning stood in the middle, and Bai Yang saw his face turn first red, then blue, and finally white like a traffic light. He raised his right hand and grabbed his chest with a painful expression.

He remembered that the heart was on the left side.

So he switched to his left hand and tightly grasped the shirt on his chest. His expression continued to be painful, and he staggered back two steps.

Zhao Bowen and Bai Zhen quickly supported him.

"Old Wang, what's wrong with you?"

"I...I had a heart attack..." Wang Ning was out of breath.

"When did you have a heart attack?"

"From now on."

The three of them left the room. Bai Yang sat at the table. Through the wall, he could vaguely hear his father and the others arguing. At first it was a discussion, but later it was just a quarrel. The sound could continuously penetrate the wall and headphones. Bai Yang could vaguely hear it.

"Isn't the propagation speed of electromagnetic signals also the speed of light?" This is Zhao Bowen, "No one will believe you if you tell me!" This is Wang Ning, and "It's fucked up" this is Dad.

Dad Wang Ning and Zhao Bowen had been arguing in the living room for half an hour. Suddenly it became quiet. They sat in silence for a long time, both wanting to speak but not speaking. Finally, the three of them stood up at the same time.

"I'm going to the bathroom."

"I'm going to smoke a cigarette."

"I...I'm going!"

Bai Yang went downstairs to throw away garbage and saw Zhao Bowen sitting on the stairs on the first floor of the unit building smoking.

The light in the corridor was very dark, no lights were turned on, and Lao Zhao just sat silently in the darkness, with only the red cigarette butt flickering slowly.

"Uncle Zhao."

Zhao Bowen stepped aside, and Bai Yang sat down next to him. The two sat side by side on the steps, looking at the black green belt outside the unit door and the lights of the residential buildings opposite.

"Yang Yang."

"Um?"

"You have made great achievements." Zhao Bowen smiled, "You may have changed the destiny of all mankind."

"Don't make fun of me."

"No kidding, really." Zhao Bowen blew out a smoke ring and held the half-burned smoke crumpled on his fingers. "You have made a major discovery that is absolutely unprecedented and probably unprecedented. If you want to list it,

If you make a list of the one hundred most important people since the birth of mankind, Yang Yang, you must be among them. Emperors of Qin, Han, Wu, Emperors of Tang and Song Ancestors will at most be listed with you, Bai Yang."

"Don't be rude to me, Uncle Zhao." Bai Yang held his chin and stared blankly at the residential building opposite. The building was brightly lit, and behind every window was a peaceful and happy family.

Human civilization will be destroyed in five years. Under such circumstances, what is the significance of listing the one hundred most important people in human history?

Is it a summary of the dead person’s life before he is buried?

"Would you like to give an acceptance speech?" Zhao Bowen asked.

"Thank you CCTV, thank you BTV, thank you, thank you, thank you NGA, thank you Zhihu Weibo Baidu Tieba." Bai Yang said.

"good!"

Zhao Bowen clapped his hands.

The applause fell and silence returned.

Lao Zhao put the cigarette in his mouth and took a long drag. The red-hot cigarette butt suddenly became bright in the darkness.

"It is no exaggeration to say that today may be the most important day in the millions of years since humans left Africa. We are witnessing history."

"But it's just an ordinary day." Bai Yang raised his head and looked at the sky.

"Any day in history is an ordinary day." Zhao Bowen smiled. "The great changes seen by later generations are just a day of eating and sleeping as usual in the eyes of those who have experienced them personally."

"Is this always the case?"

"It's always been like this."

Lao Zhao smoked silently until there was only a butt left.

"What are you going to do about this?" Bai Yang asked.

"We can't sit still and wait for death. We must find ways to change that future." Zhao Bowen replied.

"How to do?"

"I don't have a clue at the moment." Zhao Bowen shook his head, "I'm afraid it will be difficult for us to solve this problem on our own, but everyone is adding fuel to the fire. When I report this matter, the state machinery will start to spin.

Those messy top think tanks can always find a way."

"Uncle Zhao, you are also a professor at Nanjing University."

"Associate."

Zhao Bowen threw the cigarette butt under his feet and stepped on it hard.

"I'm still confused now." Bai Yang said suddenly.

"Where are you confused?"

"Everything is confusing." Bai Yang patted his cheek, "Why did this happen, and why was there communication across time and space? Why did the time capsule transmission fail? Is it really because it was dug out?"

"I can't answer your first question." Zhao Bowen said, "No one knows why this happened. I guess the problem is not with us, but with BG4MSR."

"Black Moon?"

"It may be caused by the black moon." Zhao Bowen nodded, "It's just that we can't find direct evidence yet to prove that it is the culprit of hyperspace communication."

"Isn't it obvious?" Bai Yang asked, "It is the only object beyond our knowledge."

"It is obvious, but until definite evidence is found, it can only be said to be highly suspect." Zhao Bowen said, "As for the following questions, I have been thinking about it for a while and came up with some unreliable speculations.

It's just my imagination, but I can tell you about it, and I won't be legally responsible for telling you anyway."

"Uncle Zhao, tell me!" Bai Yang cheered up.

"First of all, Yang Yang... do you think it's difficult to send a time capsule, a slow delivery of time, twenty years later?" Zhao Bowen took out a pack of cigarettes from his pocket and took out another one.

He smoked more cigarettes today than he usually does in a week.

Bai Yang was stunned for a moment when he heard this question.

"Disaster?"

"No, it's not difficult. In fact, it's not difficult at all." Zhao Bowen clicked the lighter and lit the cigarette in his hand. "Lao Wang's idea is right. It's not difficult to bury a time capsule. Put it in

It’s not difficult to send it twenty years later, but why have we failed so many times?”

After asking this question, Lao Zhao took a deep breath.

"Because the world is destroyed and society is in turmoil." Bai Yang replied, "The capsule will be dug out."

"Yes, that's the reason. It should be said that it's very likely, so we need to be double-blind to prevent anyone from knowing what the capsule is and where it is at the same time." Zhao Bowen nodded, "But we have to learn to see through the phenomena.

To get to the essence, Yang Yang, you must learn to extend a single case to a general field."

Zhao Bowen picked up a stone from the ground.

"Yang Yang, if I throw this stone into the green belt at the door now, do you think it will survive twenty years from now?"

Bai Yang was startled.

Without waiting for his answer, Zhao Bowen revealed the answer himself, "It must be possible. We throw this stone into the green belt casually. As long as there are no accidents and it is not too unlucky to be crushed by a car, it will definitely be intact."

After all, no one will have trouble with an inconspicuous stone if it stays there for twenty years."

Bai Yang nodded.

"But" Zhao Bowen changed the topic, "If we want to send this stone to BG4MSR twenty years later, and still throw it into the green belt, can we do it?"

"cannot."

"Yes, you can't. If you want to give a stone to BG4MSR, you must stuff it into a time capsule and follow the double-blind rules, otherwise it will fail. If you just throw it into the green belt, it will not be delivered to the other party 100% of the time.

." Zhao Bowen asked, "Why are the two results so different from the same stone?"

"Because in the first case, you don't have to give it to a specific person. No matter where the stone wanders to the ends of the earth in twenty years, it will still be there." Bai Yang said, "But in the second case, you need to give it to someone, then

It’s much more complicated.”

Zhao Bowen nodded, "What is the essential difference?"

Bai Yang pondered for a few seconds, "The essential difference..."

"Don't worry about it, let's look at the second example." Zhao Bowen still used stones as an example, "Now let's pick up two more stones, a total of three stones. Let's throw these three stones into the green belt.

Will they survive twenty years from now?"

"Can."

"Yes, you can." Zhao Bowen said, "Then let's arrange the three stones in a straight line. Yang Yang, can this stone array be successfully preserved twenty years from now?"

"No." Bai Yang said, "It will definitely be disrupted."

"Why are the same three stones, but the results are so different?"

"Because... in the first case, you don't need to take into account the formation. The formation is too easy to be disturbed and disrupted by others."

"Yes, but this is an appearance. We have to see the essence. Only by seeing the essence can we draw inferences and find other ways to transport time slowly." Zhao Bowen nodded, turned his head, and raised two fingers, "Yang Yang
