The two of them walked out of the room, and they could not see each other's faces.

There are a large number of relics of the Knicks civilization on display, and many people will stop and study with relish when they pass.But neither of them had such an unhappiness.

“Coughing...”

Yi Feng cleared his throat, no way, as a man, he can only be the first to throw this topic.

“Or have you been alive, right?”He didn’t know what to say, and that’s what he said at the beginning.

As soon as I spoke, Yu Yifeng scolded himself for being stupid, how to talk without going through the brain.He may be a leader when he is used to speaking very straight, and has something to say.

In particular, the group of scientists also liked such an efficient way of communication ... for a long time, it was like forming a habit.

But this is not the past...

Yu Yifeng was very sorry, but when he said the water thrown out, he did not know how to make up for it.

Hearing this strange words, Lily only hummed in a low voice, frowned slightly, and followed.

An atmosphere called embarrassment spread between the two.

Yu Yifeng coughed twice again to cover up his embarrassment: “Well, I don’t mean that...”

But he couldn’t say what it meant, actually.In his heart, he really agreed to "take it together", and saved it from being nagging by the grandparents.Of course, there is a good feeling in the heart, but also on the one hand.

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

If it was a normal woman, she would have been angry and half dead, but she would not.

She carefully considered it, found that this method seemed to be good, and finally said vaguely: "Breproduction is the instinct of life, is the natural need of genes."Life that cannot reproduce has long been eliminated in the long river of time.”

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

"Marriage is probably a compromise after the best strategy for male reproduction and the best strategy for women, which is Pareto's optimal Nash equilibrium..."

Yes, this statement is very scientific, and Yi Feng will not reflect what she means for a moment and a half.

What Pareto optimal, Nash equilibrium...

But what she said was very much in line with her character.

Marry a wife like this... well, it’s okay, sloppy can accept...

What love, marriage and so on, if it comes down to biology and sociology, is not so embarrassing.

But the lily’s face was red.She was also said by the elders that there was no way to come... There are old leftovers at home, it is impossible not to be urged, it is really embarrassing.

"That's it."

Yu Yifeng was silent for a long time, did not figure out the specific idea of lily, and said a word of things that he did not know the meaning.

He said he repented, what is "that's it"?

Lily was silent for a moment and said, "All right."

What is “good”?

He was just shocked, just casually said a word, and then got a "good" reply?

He did not understand at all, instinctively wanted to grab his own hair, but was blocked by the power armor helmet...

Maybe... agree, right?

Today, Yu Yifeng finally understood the meaning of a word: an awkward conversation.

During the conversation, the two have reached their final destination: a fully sealed super-large building, and the latest large building built by the central headquarters.

It is mainly distributed here with bedrooms, restaurants and various small offices, etc., which will be their future office area.

The building has a Class 4 biocontrol standard, and no Knicks star items can be brought in here.

Once entering the door, the power armor needs to be rinsed with boiling boiling water all over the body, and then disinfecting it with a high temperature of two or three hundred degrees Celsius before entering the next safety door.

After a disinfection procedure, the two came to the dressing room inside the building, took off the power armor, and suddenly felt relaxed.

In this large building, all the environments meet human standards for survival, and there is no interference from extraterrestrial microorganisms, and humans can survive normally inside.You don’t have to wear a power armor!

It is also one of the best working environments for the Knicks, except for the gravity environment, and the rest are close to Noah.

Humans have been coming to the Nix Star for so long, and all kinds of microbial vaccines and drugs have come out, getting rid of the dilemma of no resistance.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, and it was almost adapted to the environment of the Knicks planet, and its antibody serum became a specific drug.However, its production is very limited, and it is better not to be sick or not sick...

“Come on, let’s go eat first.”

It is difficult for Yu Yifeng to get rid of this embarrassing feeling.His face was still very thick, and soon pretended to be a man who was okay, as if the embarrassing chat had not existed.

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

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

"Of course I know."

Lily seems a little angry, but she is still very serious about her work, and can only say in a bad way: "Some of the cracking work is still my treatment."

In that electronic memory similar to the USB stick, most of the books are romance novels and online novels.It is a product of illusion.These things are not really much value, at most can only deduce the standard of living of the Knicks at that time.

Humans also have no effort to appreciate the level of the art of the Knicks civilization.

But there are some children's books, and most of the things inside are real and the value is relatively high...

From this point of view, the owner of this u-panel may be a female creature with children, and of course, a male creature may also be.And their thinking is very similar to that of humans.

Yu Yifeng shook his head and smiled bitterly: "Unfortunately, in these books we have found only part of the history of the Knicks civilization, but we have not found the cause of their extinction."

Lily continued to say unfailingly, “Of course, this kind of thing can’t be!”History is something that has already happened and can be written down.But in the future mass extinction event, they can't know."

“If they were alive after a mass extinction event, it wouldn’t be called extinction.That in itself is a paradox.”

Yu Yifeng shook his head, “That’s not necessarily.The mass extinction event must have been sequential, first there was a crisis, and then they found that the crisis was difficult to solve, and all the people gradually died step by step, and it was impossible to die the entire planet in an instant?"

"Even if the attack of interstellar civilization is not possible to kill all the population in an instant, there will inevitably be a small number of survivors who continue to survive."So, as long as there is a order, there will definitely be someone left behind a diary or something like that."

"This is extremely important to us, even less than the amount of technology that is about to be obtained!"We have to understand how they went extinct.”

Speaking of this, Yi Feng has forgotten the embarrassment just now, but is deeply worried about the future of mankind...

It is a bit strange that such a powerful civilization has become extinct.

Is it external factors or internal factors?

All have developed to this point, and there will be an internal war.

Will humans have such a problem?

Looking at Yi Feng's hard thinking, Lily's eyes brought a smile: "I think the possibility of alien strikes is very small, really want to hit, you can directly blow the planet."They are likely to be extinct for internal reasons.”

“Remember those nuclear radiations... they’re not Earth here, there are not many cities in total, and most of them rely on volcanoes or nuclear power plants for energy.”As long as a few nuclear bombs destroy, the population will be drastically reduced.”

“And even if there is no survival diary or the most direct evidence, we can draw out all kinds of clues...”

“And... didn’t you say we were going to be an interstellar civilization?”No matter how difficult it is, whether there is a one-hundred-dollar pass rate of life, we will all become interstellar civilizations, right?”

In the face of the lily son's serious eyes, Yi Feng slightly froze.

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