The two walked out of the venue one after the other, and neither could see each other's faces. Ｘ

There are a large number of relics of the Knicks civilization on display in the surrounding area, and many people will stop and study them with relish when they pass by. But neither of them had such a casual elegance.

"Ahem......"

Yu Yifeng cleared his throat, there was no way, as a man, he could only take the lead in throwing out this topic.

"Why don't you just make it live?" He didn't know what to say, and it started with something like this.

As soon as the words came out, Yu Yifeng scolded himself for being stupid, how could he speak without thinking. He may be used to being a leader, speaking very straightforwardly, and saying something.

In particular, the group of scientists also liked this efficient way of communicating...... Over time, it's like a habit.

But this is not the time it used to be......

Yu Yifeng regretted it very much, but he didn't know how to make up for the water that he spilled when he said it.

Hearing this strange words, Yuriko just snorted under her breath, frowned slightly, and then followed.

An atmosphere called awkwardness spreads between the two.

Yu Yifeng hurriedly coughed twice to hide his embarrassment: "Uh, I didn't mean that......"

But he couldn't say what it meant, but that's what it was. In his heart, he really agrees with "just make do", so as not to be nagged by aunts and uncles. Of course, having a good impression in your heart is also one thing.

Obviously, Yuriko is not a normal woman, and her thinking is also very unusual.

If it were a normal woman, she would have been angry half to death, but she wouldn't.

She thought about it carefully, and found that this method seemed to be not bad, and finally said quietly: "Reproduction is the instinct of life, and it is the natural need of genes. Lives that cannot reproduce have long been eliminated in the long river of time. ”

“…… Love is a conspiracy that leads you to reproduction, a poetic description of the impulse to reproduce. ”

"And marriage is probably a compromise after the contest between the optimal strategy of male reproduction and the optimal strategy of women, and it is the Pareto optimal Nash equilibrium ......"

Yes, this statement is very scientific, and Yu Yifeng won't be able to react to what she means for a while.

What is Pareto optimal, Nash equilibrium......

However, the words that came out were very much in line with her character.

Marry a wife like this...... Well, it's okay, so-so is acceptable......

What kind of love, marriage and the like, if it comes down to biology and sociology, it is not so embarrassing.

However, Yuriko's face was flushed. She was also told by her elders that she would come when she had no choice...... There are older leftover girls in the family, and it is impossible not to be urged, what an embarrassing thing please.

"So be it."

Yu Yifeng was silent for a long time, and he didn't figure out Yuriko's specific thoughts, and said something that he didn't know what he meant.

After he said it, he repented, what does it mean to "that's it"?

Yuriko was silent for a moment and said, "Okay." ”

What does it mean to be "good"?

He was simply stunned, he just just said a random sentence and then got a "good" reply?

He didn't understand it at all, and instinctively tried to grab his hair, but was blocked by the power armor helmet......

Maybe...... Is it the meaning of consent?

Yu Yifeng finally understood the meaning of a word today: awkward chat.

During the conversation, the two of them had reached their final destination: a fully sealed super-large building, which was also the latest large building built by the Central Command.

There are bedrooms, dining rooms and a variety of small offices, which will be their future office area.

This building is subject to Level 4 biological control standards, and no Nix items are allowed here.

As soon as you enter the door, the whole body of the power armor needs to be rinsed with boiling water, and then disinfected with a high temperature of two or three hundred degrees Celsius before entering the next safety door.

After the disinfection procedures, the two came to the changing room inside the building, took off the power armor, and suddenly felt a sense of relief.

In this large building, all the environments meet the standards of human survival, and there is no interference from alien microorganisms, so humans can live normally inside. Finally, I don't have to wear power armor all the time!

It's also one of the best working environments on the planet, with the exception of gravity, which is close to the Noah.

Human beings have been on Nix for so long, and all kinds of microbial vaccines and drugs have come out, and they have got rid of the dilemma of being defenseless. And in the process of excavating the ruins, a variety of drug formulations have also been discovered, speeding up the defense process against microorganisms.

The big black dog's immune system also played a major role, it almost adapted to the environment of the planet Nix, and its antibody serum became a miracle drug. However, its production is very limited, and it is better to be able to get rid of it or not to get sick......

"Let's go, let's go eat first."

Yu Yifeng finally got rid of this embarrassing emotion. He was still very thick-skinned, and he quickly pretended to be fine, as if the awkward conversation just now had never existed.

"Do you know about Thor? The electronic storage device that was excavated, and the map ......" Yu Yifeng asked as he walked, shifting the topic.

When it comes to work, there's always so much to say.

"Of course I do."

Yuriko seemed to be a little angry, but she was still very serious about her work, so she could only say angrily: "I still handle some of the cracking work." ”

In that USB flash drive-like electronic memory, most of the books are romances, networks. It is purely the product of fantasy. These things are actually of little value, and at most they can only deduce the standard of living of the Knicks at that time.

Nor do humans have the time to appreciate the artistic level of the Nix civilization.

However, there are also some children's books, and most of the things in them are real and have a relatively high value......

From this point of view, the owner of this USB flash drive may be a female creature with a child, and of course the male creature may not be a male creature either. And their thinking is quite similar to that of humans.

Yu Yifeng shook his head and smiled bitterly: "It's a pity that we only found part of the history of the Nix civilization in these books, but we didn't find the reason for their extinction. ”

Yuriko continued to say angrily: "Of course there can't be such a thing! History is something that has already happened, and it can be recorded through writing. But future mass extinction events, they can't possibly know. ”

"If they're still alive after a mass extinction event, it's not extinct. This is a paradox in itself. ”

Yu Yifeng shook his head and said, "That's not necessarily. There must be a sequence of mass extinction events, first there is a crisis, and then they find that the crisis is difficult to solve, and all the population is dying step by step, and it is impossible for the entire population of the entire planet to die in an instant, right? ”

"Even if an interstellar civilization attacks, it is impossible to kill all the population in an instant, and there will inevitably be a small number of survivors who will continue to survive. So, as long as there is an order, there will definitely be people who leave diaries and stuff like that. ”

"That's so important to us, if not less than the amount of technology we're about to get! We have to understand how they became extinct......"

Speaking of this, Yu Yifeng had forgotten the embarrassment just now, but was deeply worried about the future of mankind......

It is a bit inconceivable that such a powerful civilization has become extinct in this way.

Is it an external factor or an internal cause?

It's all developed like this, will there be an internal war?

Will human beings encounter such a dilemma?

Looking at Yu Yifeng's thinking hard, Yuriko had a smile in his eyes: "I think that the possibility of aliens striking is very small, if you really want to strike, you can directly blow up the planet." It is likely that they became extinct for internal reasons. ”

"Remember all that radiation...... They are not the earth here, there are only a few cities in total, and most of them rely on volcanoes or nuclear power plants for energy. As long as a few nuclear bombs are destroyed, the population will be drastically reduced. ”

"And even if we don't have a survival diary or the most direct evidence, we can deduce it from all kinds of clues......

"And ...... Didn't you say we'd be an interstellar civilization? No matter how difficult it is ahead, whether there is a large filter of life with a one-hundredmillionth pass rate, we will become an interstellar civilization, right? ”

Facing Yuriko's serious eyes, Yu Yifeng was slightly stunned.

He thought for a long time before he said solemnly, as if he had sworn an oath: "Yes, we will!" ”r
