"Speaking of which, I'm quite curious about how they maintain the number of people, the highly perfect social system, even if the peripheral environment is bad, relying on this city can easily reproduce offspring, how can thousands of years not blow up their city. After Momur left, Filna said with some confusion.

"The area below the propulsion city is significantly larger than the thrusters above, perhaps in the process of expanding the surroundings. Xiao Qi looked at the thruster in front of him that was still pumping energy, thought about it and said.

Wang Chen smiled and sent a three-dimensional mapping map, "This is the underground cavity information scanned by Ergouzi, the diameter of the surface base below is almost ten times that of the thruster above, and there are a large number of tunnels around, maybe they want to build a transportation network based on the underground." ”

Although it was not possible to map in great detail, even the most basic probe of Salty Fish had gained a lot of information.

From the picture, it can be seen that there are countless tunnels around the underground city under the thruster, spreading like a distance, Wang Chen estimates that this civilization should want to connect all the advance cities, and use the underground passage to dispatch the population and distribute materials.

If it is true, this is a lot of work, but once it is successful, it will further guarantee their safety.

Flower growers need an old saying, "If you want to get rich, you must first build roads."

With roads, new gathering places can be created based on underground transportation networks, and the ubiquitous wind and snow will provide water for the heating equipment, which will then be piped to deliver the heating in all directions.

Once the underground network is formed, the ability of the entire civilization to withstand damage will be increased by a certain amount, which is a preparation for a protracted war.

Looking at the three-dimensional drawing, Filna touched her tail and couldn't help but pick her brows, "This amount of work... No wonder it is so poor, it is estimated that many raw materials can only be imported. ”

"Yes, those fleets alone can't supply such a huge factory, but since it's the path you chose, you can only grit your teeth and continue to walk. Wang Chen said lightly.

They can only be a spectator in this matter, and just sigh in their hearts.

The next morning

Wang Chen, who had just had breakfast on the Salted Fish, received a communication from Momur, saying that the top had agreed to Wang Chen's deal, using the full set of drawings of the current thruster plus the price of three million transaction points in exchange for the technology related to the ternary fire crystal in Wang Chen's hand.

Wang Chen, who was eating, couldn't help but be happy when he heard the news, did he agree?

Although it was not unexpected, when the other party really agreed, Wang Chen was still a little excited.

After calculating it, he didn't lose anything, and he got a complete set of drawings for the thruster.

Wang Chen felt that he had vaguely touched another use of the mall, how much Chinese in the universe is, as long as he invests in it, he can not say that he can make a lot of money, but he can also enrich his own heritage.

Especially in this kind of low-end civilization, trading with them is essentially building their own relationship network, and this time the relationship network will have contacts.

Maybe I will have to go to those low-end civilizations in the future, especially this kind of civilization with a more difficult life, maybe you can make a fortune.

The transaction was made through official channels, and the technology provided by Wang Chen must ensure the accuracy of its parameters, and if there is a suspicion of exaggeration, Momur has the right to apply for a refund through official channels.

This can be regarded as a kind of protection for them, even if Wang Chen himself is a businessman, he has to admit that businessmen are creatures who naturally like to fool.

How honest a person I used to be, how many people have been fooled since I came into contact with this industry.

Sure enough, people are all eels, and after all, they have to live like the kind of person you didn't like the most before.

The exchange of technology was very fast, as an official cooperation point, although it was very barren, the relevant equipment was still complete, and soon a standard contract was issued to Wang Chen.

After letting Ergouzi check it and making sure that there was no problem, Wang Chen entered his personal information with his identity information.

The whole process of signing the contract was online, and after the triplicate was collected, Wang Chen passed on the technology of the ternary fire crystal to Momur.

And the data about the promotion city is still being sorted out, and Momur asked Wang Chen to stay for a little time, and the integration will be completed around tomorrow.

After all, there are a lot of things involved in them, and some sensitive things need to be eliminated.

After all, the blueprint of a city will definitely be made up of some dark sides, and Momur doesn't want to let himself know that he is probably afraid of impressing the image of his civilization in Wang Chen's mind.

Wang Chen understood this, and it was not a big deal to delay for one more day.

Moreover, the three million trading points have been credited to Wang Chen's account.

Momur seemed to be really busy, and after remitting the money to Wang Chen's account, he said goodbye to the flash people and said that if you want to visit the city, you can contact him, and he will arrange someone to help guide him.

Filna didn't have much desire to go shopping, after all, it was undoubtedly too backward compared to the previous Paimon City, even if it was the largest planet in their civilization.

The things sold in the commercial areas are low-end and underdeveloped, and more of them are supplied to their local shops.

Seeing that the big guys were not interested in going out, Wang Chen didn't bother to go out to blow the wind, and asked Momur to lock it on the salted fish as soon as possible and roast the fire.

The temperature around here seems to be lower, especially the visibility has been reduced to about five meters, and Ergouzi said that a huge storm is coming.

At this time, only one spaceship, the Salted Fish, was quietly parked here in the port of Nuoda, and in order to resist the wind and snow, the two dogs also increased the energy supply a little.

In the evening, a blizzard came.

Looking at the temperature that was about to fall below minus 90 degrees, the engines on the periphery had increased their energy supply at night, and bursts of huge energy stood in the wind and snow with dull noise.

Ergouzi showed that the temperature of the energy core had exceeded more than 300 degrees at this time, and the temperature of the core circle within three kilometers around the thruster had been pulled to more than minus 20 degrees and then decreased outward.

The temperature of the indoor dungeon has not changed, but the power of the thruster core has increased by 50 percent.

Not only this thruster, but there are also more than a dozen bright pillars of light in the night on the horizon to light up the skyline, and the dim lights are like a lighthouse in the night, although not too bright but not extinguished.

"Sleep, it looks like there's nothing wrong with it. Wang Chen admired it and said with a smile.

said goodbye to the audience in the live broadcast room, and then returned to his private suite on the fifth floor.

Go to bed early and get up early to be in good health, Wang Chen doesn't want to drink wolfberry at a young age.
