According to Chen Xin's estimate, if he can get supplies from Mo Qingyan to upgrade the planting greenhouse this month and replant vegetables in time, next month he will not only harvest seven times the current output, but also harvest the carrots he planted last month, which can be said to be a great harvest.

But if you really collect so many vegetables, you must deal with them in time. Chen Xin couldn't finish so many vegetables by himself. The only option is to take them out and exchange them for supplies.

Bi the large freezer he exchanged for from Mo Qingyan could fill up a few hundred kilograms of vegetables. That is, his harvest in a month now. If the actual yield increased by seven times, he would definitely have no place to put so many vegetables.

Chen Xin thought about it carefully and decided to plant the dry rice according to his original idea.

If you use materials to upgrade and increase the planting area and hydroponic planting tray, Chen Xin can completely plant dry rice on the ground and move the vegetable planting to the hydroponic planting tray.

In this way, he can not only harvest enough food to eat, but also take out enough fresh vegetables to exchange for supplies.

After all, the upgraded planting greenhouse will be 200 square meters in size, and there will be a hydroponic planting plate of the same area. The land of 200 square meters can be planted with dry rice. The harvest will be two seasons a year, and you can harvest almost 600 kilograms of rice.

As for the vegetables grown on hydroponic planting trays, half of the carrots and lettuce, the average monthly harvest can be harvested about 600 kilograms of cabbage, more than 600 kilograms of lettuce and about 300 kilograms of carrots.

Although carrots are collected every March, they are more resistant to storage and are undoubtedly a high-quality material that can be traded.

After doing this, Chen Xin suddenly found that his supplies were abundant, and he had a great surplus in both rice and vegetables.

He can completely use most of his monthly vegetable output in exchange for supplies to upgrade his shelter and make his life better. He can also change to other things to enrich his dining table, such as meat and wine.

These outputs can also be exchanged for other things Chen Xin needs, such as the small agricultural machinery he needs most now for farming, and the firearms he uses.

Of course, Chen Xin doesn't have to change his gun. He can completely exchange vegetables for supplies, then upgrade the weapon cabinet, click out the gun manufacturing drawings of the weapon cabinet, and make his own guns.

But he was not sure what the gun he made would look like. If it were the more primitive gun, it would be a little worse than the one he had in terms of reliability and usability.

After all, he could ask Uncle Ding to exchange a pistol from the Special Police Force through Ding Ning. If he made it himself, if the upgrade level was not enough, it was likely that it would be a simple firearm that did not even rifle.

That kind of gun is not unusable, but it is indeed not very practical and is not easy to carry around.

However, the upgrade of the weapon cabinet must be carried out. The old saying goes, "You must not have a bad intention, but you must be guarded against others." Having reliable weapons to protect yourself is also a guarantee for yourself to survive better in this end of the world.

Thinking of this, Chen Xin added the materials needed to upgrade the weapon cabinet to his list and decided to use the vegetables produced this month as a deposit to contact Mo Qingyan to contact Uncle Ding in exchange for the materials on the list. The final payment will be made until he upgraded the greenhouse next month and expanded the output.

Although this payment method is a bit unreliable in the end of the world, Chen Xin believes that he can still get these things with his relationship with Mo Qingyan and Ding Ning.

After making the list, Chen Xin was about to set up his communication antenna and connect his short-wave radio station so that he could contact Mo Qingyan and the others, and he would have to go to the city without saying anything.

The temperature is not too low now, so it is not a big problem to go there, but as the weather gets colder, you will suffer when you go out.

Chen Xin thought so, took out the military short-wave antenna he specially prepared from Lucia from the iron box and walked out of the shelter with the box.

The best place to set up antennas is of course the top of the mountain where his own shelter is located. However, considering that the maintenance and wiring of antennas are more troublesome when erecting on the top of the mountain, Chen Xin chose to set up antennas halfway up the mountain.

There is a cement base here that was prepared in advance. Although the fire burned here in a bad shape, the ash and residue on the surface were swept away, and the cement-poured base on the ground was still complete, just looking pitch black.

After cleaning the cement base, Chen Xin took out the short-wave antenna placed in the box and set it on the cement base. He screwed all the fixing bolts into the screw holes reserved in advance, and fixed the short-wave antenna to the cement base.

After installing the antenna, Chen Xin also needs to connect the antenna to the short-wave radio station in the shelter.

Fortunately, the cable has been buried here in advance, so there is no need to pull the wire.

Chen Xin opened the grid of the shelter ventilation port under the cement base, pulled out a cable from it, and inserted it into the interface under the antenna.

After doing all this, Chen Xin did not forget to cover a layer of camouflage cloth on the antenna to prevent anyone from finding it out.

Although there are almost no people who can appear in the wild in this end of the world, they must not be ordinary people who can appear in the wild at this time. If someone discovers the antenna, steals it for yourself or finds your own refuge, and has any thoughts you shouldn't have, it will also cause trouble for yourself.

So in order to reduce some unnecessary trouble, Chen Xin still put a layer of camouflage cloth on the shortwave radome, making the entire antenna look like a small black mound.

Looking at his own work and patting the dust on his hands, Chen Xin returned to the shelter with satisfaction.

In the shelter, Chen Xin also took out the short-wave radio station and placed it on the table reserved in the living room. He connected the other end of the cable to the short-wave radio station.

After turning on the radio switch and debugging the channel, Chen Xin then issued his first call: "This is the writer, I am calling all my survivor companions here. Please answer when I hear it. We are still alive, Live long and prosper."

This sentence is a signal they agreed upon at the beginning. When everyone contacted after the disaster, they would say this sentence to show their identity and their current status of survival.

Chen Xin was waiting, but there was silence in the short-wave radio station, and only a faint current flowed by, which made Chen Xin feel a little frustrated.

Just as Chen Xin looked at the unanswered radio station and wanted to turn it off, the sound of answering finally rang out of the radio station: "This is an old farmer, I'm glad to hear your voice, the writer. We are still alive, Live long and prosper."

"This is a drilling expert. I have ample supplies and can accommodate companions who need refuge. We are still alive, Live long and prosper."

“This is a mountain climbing tiger, and it’s good to be in good condition. I’m glad that everyone has survived this disaster. We are still alive, Live long and prosper.”

"here it is……"

Replies one by one, and listening to everyone's answers, Chen Xin's heart was filled with joy and excitement. His companions in the survival group responded at this moment, proving that he was still alive.

The last answer also reminded me of: "I am Long Niang, I am living a good life, it's great that no one has lost contact! We are still alive, Live long and prosper!"
Chapter completed!
