I! Billions of invincible identities

These rooms are all forged of steel, so the splicing is more annoying, and there are not even gaps. If you close the door, you can form a closed space inside, and then turn on the oxygen converter inside. There's no need to worry about the vacuum coming in.

In this way, it is okay for people to wear oxygen converters in the house. Everything is no different from the earth. At most, there is a lot of lack of supplies.

"On the moon is more like a city trip, and there is nothing high-tech. After all, there are too few materials on the moon. After these minerals are produced, they are only for me to forge a steady stream of cities, and it is still difficult to develop the other 15 things, at least I can't do it. "

Xiao Tian's helpless stall hand said. Just like on the moon, mobile phones are now no longer usable. But if you want to build a signal base station on the moon and establish your own communication on the moon, it is tantamount to being more difficult than going to the sky.

After all, if you want to establish your own communication, at least you must have a medium for communication. But there is no doubt that vacuum cannot be transmitted as a medium.

That's why you want to connect on the moon unless you're close enough to communicate directly face to face. Otherwise, it would be too difficult to deliver the message.

"Everything is difficult at the beginning, anyway, you can't eat a fat person. We can even build a thick nutrient layer on the surface of the moon later. In that case, or the moon would be the same as the Earth. "

Yang Fan said about the water in Xiaotian's room. Xiao Tian does not drink water, but this water is also prepared by Xiao Tian for Yang Fan in advance.

But after taking a sip, Yang Fan only felt that this water was a little strange, and raised his cup to Xiaotian.

"Master, this water is artificial water. I synthesize a type of water using oxygen atoms and hydrogen atoms. At least much purer than the water on Earth. It can achieve 99.9% purity. "

Xiao Tian explained to Yang Fan. After all, there is no water source found on the moon. But people must have water to survive, and there is no shortage of water. Because of this, Xiaotian will use the principle of oxygen converter to create a hydrogen converter. In this case, hydrogen atoms and oxygen atoms are still used for artificial aqueousness.

Although this efficiency is not high, at least there is a solution to the source of water, so that there will be no worries as before. The last traveler, all their drinking water was brought from Earth by spacecraft.

And when the moon can be self-sufficient, those spaceships can only pull people without the need to transport supplies when they come and go between the end of the month. This also frees up more space for those people.

"Take me to the remaining two cities." Yang Fan didn't say much, he was also quite satisfied with this invention.

Xiao Tian followed Yang Fan to the two cities next to him. At this time, Yang Fan still needs to wear an oxygen converter. But fortunately, Yang Fan did not feel any discomfort, so he let the oxygen converter constantly provide oxygen for himself on his body.

Yang Fan in the distance could see that there was a hot work over there. Seeing the prototype of the city rising up, Yang Fan felt a lot more relieved in his heart. _
