An hour later.

Cao Ge and Da Shi arrived at the combat center, Da Shi did not stop at the door, but drove directly in, and then directly entered the interior in the basement.

When the two walked into the conference room, it was already full.

The movement of the two of them opening the back door did not attract their attention, and the eyes of the more than twenty people in the conference room all looked at the screen on the wall at the end of the conference table.

The picture on the screen is a closed interrogation room, and at this time there is an old man in it, and sitting opposite the old man are two officers in military uniforms, a man and a woman, and the man is Chang Weisi.

"It's already started." Dashi glanced at the picture on the screen, and then said to Cao Ge.

Cao Ge glanced at the extremely calm old man on the screen, and then followed Dashi to sit in the two empty seats at the end of the conference seat.

"Professor Wang."

"Mr. Cao."

Cao Ge said hello to Wang Miao, who came over, and then pulled out the chair and sat down.

Although the movements of the two did not attract the attention of others, Wang Miao, who was also sitting at the end, still noticed them.

After sitting down, the three of them did not communicate anymore, and looked at the interrogation screen on the screen.

"Ye Wenjie, I will now interrogate you on behalf of the country." Chang Weisi looked at Ye Wenjie and said solemnly.

"Ask if you want to know, and if I know, I'll tell you." Ye Wenjie didn't have a big reaction to Chang Weisi's words, just said calmly.

"Okay, first question, when did you start contacting the Trisolarans."

"It was the summer of 1975, and I was still at the Red Bank base......"

In the following time, Ye Wenjie explained her experience at the Red Bank Base, and everyone listened carefully, and there was no other sound in the conference room except Ye Wenjie's voice.

"In other words, the first time you communicated was in 1979." Chang Weisi said.

"Suffice it to say that in the summer of 1979, I received my first message from the constellation Centauri." Ye Wenjie replied.

"What did you do when you received the message, did you reply?"

"That's right, I told the civilization the information of the earth, telling them that the civilization of the earth can no longer control its evil behavior by its own efforts, and the earth needs their coming." Ye Wenjie said calmly.

The interrogation lasted more than an hour.

After Chang Weisi finished asking the political questions they had prepared, he handed over the interrogation to the conference room.

Then, under Cao Ge's gaze, the scientists in the conference room began to ask questions one after another about the scientific and technological problems of the Trisolaran.

Some questions they can get answers, while others can't, because Ye Wenjie herself doesn't know.

This went on for more than half an hour, and finally it was Cao Ge's turn.

"Brother Cao, you've been listening to it for so long, so there's nothing you want to ask? That's an alien, aren't you scientists most interested in that? Dashi looked at him and said.

Cao Ge glanced at Da Shi, then at the scientists in the conference room, and finally looked at the screen and said, "General Chang, I want to ask her, is there a large number of civilizations like the Three-Body Problem in the universe?" If so, where are they all? ”

Cao Ge asked the famous question.

He hoped to use Ye Wenjie's mouth to reveal a little truth about the universe to the people here.

"Teacher Ye, is there a large number of civilizations like the Three-Body Problem in the universe? If so, then where are they all? Chang Weisi in the interrogation room looked at Ye Wenjie and asked.

Cao Ge's question obviously touched the calm Ye Wenjie.

Ye Wenjie's fluttering gaze really looked at Chang Weisi for the first time, but she was silent and did not answer immediately.

"Is that a difficult question to answer?" Chang Weisi noticed that Ye Wenjie was a little unusual at this moment, so he asked.

Although Chang Weisi doesn't understand science, he understands human nature, and he saw the clues from Ye Wenjie's reaction, and this question seems to have asked the key.

Ye Wenjie met Chang Weisi's gaze, was silent for a long time, and then spoke: "If I have to answer, I will say that I don't know, but in a scientific way, there should be many intelligent civilizations in the universe." ”

"If there are many intelligent civilizations in the universe, then where are they, why haven't we found them, are they hiding?" Cao Ge continued to ask.

After this question was asked, Ye Wenjie's silence increased greatly, and after a long time, she slowly raised her head, looked at the camera placed in the corner of the interrogation room, and said solemnly: "I don't know." ”

Cao Ge looked at Ye Wenjie's solemn expression and knew that he couldn't ask any more, because if he continued to ask, he would be in danger.

After all, before this, it can be seen as a question asked by his curiosity about the universe as an anthropologist.

Because he asked a question that already existed – the Fermi paradox.

Cao Ge felt that it was enough to ask this, at least to give Chang Weisi and his party a wake-up call and let them pay attention to this problem. As for whether they can think of the law of the dark forest from this question, it has nothing to do with him.

"General Chang, I don't have a problem." Cao Ge said into the microphone.

Chang Weisi, who received the information, sorted out the information in his hand, and then said to Ye Wenjie: "Teacher Ye, then we will go here for today's interrogation first." ”

……………………

After the interrogation, Cao Ge was specially invited to Chang Weisi's office.

Cao Ge sat on the sofa and looked at Chang Weisi, who was also sitting on the sofa.

"Mr. Cao, Ye Wenjie's reaction to the question you just asked was obviously unusual, why did you ask this question, do you have any considerations?" Chang Weisi thought for a while, then looked at Cao Ge and asked.

"General Chang, you think too much, I don't think about it, I'm just curious, since the Centauri constellation that is so close to us can have a civilization, then the universe is so big, how many civilizations will there be? But so far, we have only discovered the existence of the three-body civilization, but unfortunately, she did not answer my question. Cao Ge said as he looked at the sky outside the window.

Chang Weisi looked at Cao Ge, first lowered his head and was silent for a while, then looked at him with a frown and asked, "Is this question important?" ”

Cao Ge took his eyes back from the window, then looked at Chang Weisi and said seriously: "I don't know. ”

Chang Weisi looked at Cao Ge and was silent for a long time.

Half an hour later, Cao Ge walked out of the combat center.

"Brother Cao, why aren't you surprised at all, it's an alien?" On the way back, Dashi asked while driving.

"What's so surprising, you see who is surprised in the combat center, the universe flickering, the earthlings can't do it at all, and the universe itself can't flicker, I don't believe in ghosts, so only aliens are left, and I always thought that there were aliens, and this cosmic flickering just happened to prove this." Cao Ge said.
