At the Mars Base, when Chen Mengchuan was eating in the cafeteria, Xu Shuwei, Lu Jianglan and Chen Xiaoyun came over.

"Look at your posture, you have something to look for me." Chen Mengchuan asked them with a smile, the mood still seemed to be good, the situation of humanoid robots on the earth had begun to slowly stabilize, even if there were some small waves, it would not affect the overall situation. After that, it's time to see Ah Chen's evolution.

"Haha, of course there is something, otherwise we wouldn't have to find it together." Xu Shuwei laughed and put down the plate in his hand.

"I'll go get some more food, you eat first, and I'll come and talk." After putting the plate away, he added another sentence.

Chen Mengchuan and the others smiled and asked him to go quickly.

After a while, Xu Shuwei brought another plate of the same amount of food.

"Brother Xu, this is not what you said you should do to lose weight, to be honest, although our biological resources on Mars have entered a virtuous circle, they can't stand you eating like this, if they are all like you, this biological cycle will be eaten by you." Chen Mengchuan laughed and teased him.

", eat you a little, and scream. I've only had 10 fried chicken wings, and I haven't eaten them in days. ”

"Okay, let's talk while eating, what's the matter?" Chen Mengchuan asked him.

Xu Shuwei swallowed a piece of fried chicken wings in a few bites, threw the two heel bones on the bone dish area of the plate, and said, "It's some thoughts about the Martian city." ”

Chen Mengchuan smiled and looked at him seriously: "Brother Xu, do you think it's time to establish a Martian city now?" ”

His question relieved Xu Shuwei, and began to pretend to be pitiful and complained: "It's not that I think it's time, but in such a working atmosphere, many people are a little sensitive, and there have been a lot of frictions and conflicts in the base recently, I think you should know." ”

"It's just these things, over and over, in the end, everyone still misses home, and their emotions have been suppressed for a long time. Instead of returning to Earth on regular holidays, it is better to build a Martian city directly, so that people who are willing to move in and live can move in, and to a certain extent, they can also prepare for many things in the future, you think about it. After Xu Shuwei said this, he didn't go to see Chen Mengchuan, and continued to pick up a fried golden chicken wing and eat it.

After Chen Mengchuan heard his words, he frowned slightly.

Xu Shuwei's words are not unreasonable, many people have all kinds of negative emotions during the long hours of work on Mars, although they have tried their best to improve the environment of the Mars base, but after work, they can only communicate with their families through video, which is obviously not enough.

Chen Mengchuan himself misses his daughter very much, and he really wants to be able to accompany his daughter to play, eat, read stories, etc......

But is it really time to build a Martian city? Chen Mengchuan was hesitant in his heart.

The environment on Mars is not suitable for human habitation for a long time, and even if an independent Martian city is built, it will be a giant closed Martian city.

Although Tianzhi Technology now has enough resources and technology to build such a Martian city, deep down, Chen Mengchuan hopes to invest these resources in a steady stream of development.

Build more Martian metal smelters, produce more multi-armed crabs, more precision instrument manufacturing plants, more spaceships, and stock up on more supplies to prepare for future plans.

"Mengchuan, this is my 10th chicken wing, and it's also the last, I wonder if it's time for you to post your opinion?" Xu Shuwei picked up the last chicken wing on his plate and pointed to a pile of chicken bones on the side and said.

Chen Mengchuan looked at his hand, a plate of chicken bones, and his face was black......

"Ahem, it seems that many people have already mentioned this to you." Chen Mengchuan looked at Lu Jianglan and Chen Xiaoyun with a smile.

The two also smiled and nodded.

"A lot of people told me about it. There are many people at the bottom who have started to have a lot of bad emotions in their hearts. ”

"Why didn't Toni come with you?" Chen Mengchuan asked with a smile.

Xu Shuwei rolled his eyes: "His parents are in the United States, even when he is on Earth, he may not have to video chat with his parents once a month." ”

"Well, when I didn't ask." Chen Mengchuan smiled a little awkwardly.

Soon, the group of four people had eaten and drunk enough, and Chen Mengchuan invited the three of them to his office area, wanting to implement the things of Martian City specifically.

"Do you have any plans for the next step?" Chen Mengchuan asked.

"Xiaoyun, you take out your plan and take a look." Xu Shuwei said to Chen Xiaoyun.

Chen Xiaoyun nodded, took out the small gravitational screen he carried with him, touched it a few times, and projected it onto the big screen.

"This is a large crater north of the Martian equator, the entire crater has a diameter of 42 kilometers and an average depth of 102 meters, and my plan is to build a Martian city in this crater......"

"The first step is to dig down 200 meters in this crater to an average depth of about 300 meters, then lay a foundation at the bottom of the crater, lay the bottom of the crater, and then build 269 supporting lighthouses like this, and finally build an arc-shaped capping ...... based on the top of the lighthouse."

"After that, the construction of the internal space environment, layered buildings, green biological circulation and water recycling......"

"Finally, in the Martian settlement, the entire base is planned to accommodate 1 million to 2 million people......"

Chen Xiaoyun's plan is complete and detailed, she first preliminarily introduces the entire plan structure, and then slowly breaks it down along the timeline, and finally explains the whole plan.

Chen Mengchuan listened carefully to her plan, did not question it, and did not interrupt her soundly.

"Brother Chuan, what do you think of Xiaoyun's plan?" Lu Jianglan asked Chen Mengchuan with a smile.

"It's good, but it's obviously very idealistic, how do you understand a city?"

"Architecture, population, work, circulation, learning are all mentioned, but what about the most important regimes? A city must have a political regime after all, and we, a Martian city, must be independent from the earth, if you look at this plan, are we considered independent? Chen Mengchuan asked her slowly, and his tone was very calm.

His words stunned all three.

"People in this city always need an identity, a self-awareness, and a sense of belonging. The zoning of the city, the control of the area, and so on, these problems in the question of people are perhaps the most important. Chen Mengchuan said.

"I don't think much about that." Chen Xiaoyun said in a muffled voice.

"Then before the Martian city is established, think about it, make a more detailed plan, and elect a mayor by the way."

Xu Shuwei grinned: "Then Mengchuan, did you agree?" ”

Chen Mengchuan smiled: "Why don't you agree?" Let's start arranging to excavate today, this crater is so big, you have to dig 200 meters, this is not a small project. ”
