Chapter 85: Mo Qingyan's oxygen generator

There is really no need to make the corridor into a floor door. After all, the

first two doors have been broken through. It is not meaningful to make the

corridor into a concealed door. Can someone else enter and still find a door?

And the door is made into a floor door. After changing the structure of the

corridor, it seems that it will become inconvenient to carry materials.

Since I don't plan to move any other places, the blueprint for this gate is

ready.

Looking at the CAD design drawings made on the computer, Chen Xin couldn't

help but feel a sense of emotion. This was the skill he learned when he got

his first job when he just graduated from university. It has been a long time

since he drew drawings for so many years.

Originally, Chen Xin thought that after the end had come, he would no longer

draw drawings, but he didn't expect to use this skill again so soon.

But reality is always more bizarre and complicated than we imagined. Maybe

fate will give you an unexpected surprise.

Chen Xin couldn’t tell whether it was a surprise or a fright. He closed the

laptop again, put it on the bedside, checked the pistol in the bedside table

and placed it in the place where he could get the most easily. Then Chen Xin

went out. I turned off the bedroom light, covered the quilt and closed my

eyes.

Tomorrow, he will have to upgrade the door to make an oxygen generator for Mo

Qingyan. There are still many things.

But this feeling of fulfillment is not bad for Chen Xin.

When Chen Xin fell asleep, there was still a dim green light in the bedroom.

It was the algae oxygen generator in the corner that was working.

——————————————————

Chen Xin, who woke up early, is already sitting in front of the workbench. He

plans to prepare the oxygen generator for Mo Qingyan first.

The materials sent by Ding Ning were quite sufficient, and the oxygen

generator was enough. The only trouble was that although the glass she brought

was guaranteed to be in one piece as much as possible, there were still a lot

of broken glass that needed to be cut and spliced.

In fact, if there is a melting furnace to melt the glass and remake it into

the required shape, it is the best use of the broken glass, instead of using

glass glue to stick them together.

But for Chen Xin, he only needs glass as a raw material. With the help of the

system, he can easily process the glass into whatever he wants.

Next to the workbench at this time, the original broken glass has been

reshaped into a tall circular straight tube, and Chen Xin is making the base.

This kind of microalgae oxygen generator base is the key. The glass straight

tube is relatively just a container. It doesn't really matter what shape it is

made of, but the circular straight tube is relatively efficient in using

light.

Pipes and vacuum pumps need to be installed on the base to charge carbon

dioxide into the circular straight cylinder to stimulate the photosynthesis of

microalgae.

Therefore, the chassis should be laid with a ring-shaped pipe, and an air pump

is used to pump carbon dioxide into the pipe, so that the carbon dioxide

enters the ring-shaped straight cylinder from the small opening in the pipe.

However, the production of high-purity carbon dioxide is more troublesome, and

it is also dangerous. Therefore, Chen Xin directly uses ordinary air here,

allowing the chassis to directly absorb the surrounding air.

As for the fill light, it is installed on the top cover, because the circular

straight tube is placed upright, the dead algae will be deposited to the

bottom, relatively speaking, the light transmission will not be so good.

There are various tools on the workbench and the upgraded oxygen generator in

the bedroom as a reference. The oxygen generator for Mo Qingyan was made

quickly.

After all, the structure itself is very simple, and the technology is

relatively uncomplicated. With the help of the system, Chen Xin quickly

completed everything and assembled it together.

Compared with the upgraded oxygen generator in the bedroom, the one that Chen

Xin made by hand looks rougher, and there is not much difference other than

that. It is already used for Mo Qingyan. enough.

So after finishing the oxygen concentrator, Chen Xin did not spend survival

points to upgrade the oxygen concentrator, so he planned to hand it over to Mo

Qingyan.

Putting the finished oxygen generator aside, Chen Xin checked the time and

planned to have lunch first, take a break, and upgrade the door in the

afternoon.

Although it was just to confirm the upgrade, Chen Xin didn't plan to finish it

eagerly.

There is not much to do every day in the refuge itself. Chen Xin doesn't want

to finish everything at once, and then become idle to play games.

Of course, Chen Xin is not really nothing. The daily maintenance of the

planting greenhouse cannot be saved.

It’s just that as the crop enters the growing period, he only needs to ensure

the water supply and sunlight to maintain the operation of the planting

greenhouse.

As for the prevention and control of various diseases and insect pests that

are common in general greenhouses or greenhouses, Chen Xin is naturally also

very concerned.

But I don’t know if the seeds I bought are good, or if the system-upgraded

planting greenhouse has black technology. At least so far, Chen Xin has not

encountered any crop diseases and insect pests, and all the crops are growing

healthy.

The upland rice he planted has now entered the long ear

stage~www.mtlnovel.com~ From the young ears to heading development, this

process will last about 30 days. According to the growth cycle, these upland

rice should enter the fruiting period in a few days. Period, began to head.

I have to say that Chen Xin had never planted fields before. After he really

started to grow dry rice, he realized that the so-called dry rice is planted

twice a year because the environment and climate do not allow it.

If it is in a planting greenhouse, let alone two seasons a year, he can plant

three seasons a year.

In this way, Chen Xin found that after he expanded the planting greenhouse to

the current 200 square meters, if he uses half of the land to grow upland

rice, he can harvest about 600 catties of rice a year. Although not a lot, it

is at least as a staple food. It is enough to maintain Chen Xin's consumption

alone.

Even if Chen Xin upgrades his planting greenhouse again, he upgrades the

current single-layer hydroponic planting to multi-layer hydroponic planting,

all used to grow vegetables, and the land is used to grow upland rice, his

output can even afford one or two more. personal.

As for the further upgrade, the fish-vegetable symbiosis cycle system and

animal breeding can be created. Simply raise some fish or poultry such as

chickens and rabbits, so that more people can survive.

And more importantly, Chen Xin can now exchange vegetables for food from the

SWAT team.

Although the food from the shelters that Qin Lan had brought before was really

unsatisfactory in terms of taste and texture, at least it was food, something

that was edible, and it was still considered good food today.

Speaking of food, after Chen Xin thought about it for a while, he decided to

eat the roasted mouse meat with mushrooms that Qin Lan brought at noon today.

As for the canned meat from Mo Qingyan, he can keep it and eat slowly.

After all, rat meat is eaten now, but pork is not sure when it will be eaten

again.
