Chapter 400

"Ah LAN, long Niang, do you think there's anything to be changed in the shelter now?" In his own shelter, Chen Xin spread out a blueprint of the current shelter on the table and asked Qin LAN and Mo Qingyan who were sitting in the room.

Now that he has decided to upgrade his refuge and the scientific research base to be built together with the military camp, Chen Xin has decided to ask everyone's opinions to see how to adjust his refuge.

With Chen Xin's inquiry, the blueprint spread out on the table also projected a 3D stereo projection. The light blue lines formed the structure of the current refuge, and the text instructions were carefully attached.

Looking at the projection of the shelter in front of him, Qin LAN asks Chen Xin curiously, "Xin, do you want to transform the shelter?"

"Yes, I accepted the title of academician of the highest Academy of Sciences issued by the state and the corresponding treatment. One of them is to build a scientific research base for me. I plan to put this scientific research base on it and transform the refuge by the way." Chen Xin explained to Qin LAN and gave them a special look: "I used to live alone, and then the transformation was nothing more than adding a few more rooms and adjusting the structure, but now you still have your parents and Han Ping and their two brothers live here, so it's better to transform them again."

"That's true, but there is a lot of work to be done in the reconstruction of the refuge. It's a bit too much to do with the walls and the earth and stone excavation, isn't it? Now that the shelter is very comfortable, I don't think it's necessary to make trouble. " Mo Qingyan shakes her head after hearing Chen Xin's words. She doesn't seem to support Chen Xin's reconstruction of the refuge.

It's normal. After all, if you don't use the system upgrade, from the perspective of normal people, if you want to reconstruct an already built underground shelter on a large scale, the construction volume is really large. In Mo Qingyan's view, it's unnecessary.

Chen Xin could not deny this, but only nodded slightly, but still asked them: "I will solve the construction problems. Without considering the construction problems, do you think there is anything that can be improved in the shelter now?"

Hearing Chen Xin's question, Qin LAN and Mo Qingyan look at each other. Although they don't understand why Chen Xin wants to transform the comfortable shelter that seems to be living now, they still don't firmly oppose Chen Xin. After all, they just make a design drawing and put forward some ideas, which is nothing.

So after they thought about it for a while, Qin LAN took the lead in saying: "I think it would be good if there was a fight training room. This time, ah Xin, you were assassinated. If you can accept some fight training and react, that person is not so easy to hold your neck."

"Fight room? Can add, just can also be used to exercise at ordinary times Chen Xin thought about it and thought it was a good suggestion. After all, he had thought about building a place for physical exercise before, but later he forgot.

As Chen Xin agreed, he pointed to the blueprint and adjusted it a few times. Next to the medical room on the first floor, he pulled out another room, which was very large.

When Mo Qingyan saw that Chen Xin had made the space on the drawing so large, she thought he was just imagining it, so she said half jokingly, "in that case, I think we can draw a special farm. Now, although there is enough space to grow in the greenhouse, the chicks have grown a little bigger. If we want to raise chickens or other livestock later, we still need to have a bigger farm It's a little bit of a place. "

Mo Qingyan's suggestion is also serious. The hens Chen Xin brought back and the chicks hatched from eggs are all raised in the planting greenhouse, but there is only a small area for these chickens to live in. The place is not big.

As the chicks are growing up, the place has obviously become a bit crowded.

If Chen Xin doesn't want to confine the chickens in cages, like the way in the past when chickens were raised in cages from chicks to slaughtering, it's necessary to make it bigger. At least, it's necessary to make the place where the chickens can move as a farm.

So after Mo Qingyan made a suggestion, Chen Xin also raised his hand and pulled out a space that could be used as a breeding farm beside the original greenhouse.

And Chen Xin also conveniently adjusted the structure and location of the greenhouse and the height of the whole shelter, poking the top of the greenhouse out of the ground.

"Well? Why poke the roof of the greenhouse out of the ground? " Qin LAN to Chen Xin such modification, immediately feel some don't understand.

The whole shelter was placed underground to avoid all kinds of natural disasters caused by the impact of meteorites. Naturally, the planting greenhouse was also wrapped in soil. However, with Chen Xin's adjustment, the top of the planting greenhouse was exposed to the ground, which is really puzzling.

"When I was near the city, I had observed that the sky would be slightly bright at noon when the light was the strongest." Chen Xin replied that it seems to have nothing to do with the exposure of the top of the greenhouse, but immediately added: "the dust in the sky is expected to gradually begin to fall within one year, and gradually return to the original light level in about three years.

Although there is still a large amount of dust in the stratosphere, which affects the light intensity, generally speaking, after three years, the sky will be bright, and the light intensity can reach the light intensity that can appear in strong haze weather.In this light intensity, although the plant growth will be relatively slow, but with the light lamp can still grow crops normally. So I put the top of the planting greenhouse out of the ground, just for this, and then I can use the sunlight to provide light for the crops by installing transparent glass and light panels on the top of the planting greenhouse

"I see. Are you going to use the light board to refract sunlight into the greenhouse?" Mo Qingyan suddenly understood Chen Xin's idea.

In fact, this method of refracting sunlight for lighting has been used since ancient times. Many high-rise buildings in modern buildings have adopted similar design. By installing refracting light panels on the external walls of buildings, the external sunlight can be refracted into the interior for lighting, so as to reduce the use of artificial lighting.

"It's a good design, but in that case, isn't the shelter going to be transformed?" Qin LAN looks at the blueprint that is changed by Chen Xin in front of him and asks him something uncertain.

Qin LAN did not ask, but if Chen Xin did, it would be too big to change the whole shelter.

Chen Xin just nodded and added some other things to the blueprint. Then he said, "the state will pay for this transformation. Of course, we need to add back some designs that were abandoned for various reasons when we built the refuge."
