After the disaster, to get in touch with friends again, to confirm that everyone survived the disaster, this is undoubtedly the most gratifying thing.

Through a brief communication on the radio, Chen Xin also confirmed everyone's current situation and learned that although everyone may have encountered some minor problems, they are basically doing well, which makes Chen Xin very happy.

After all, everyone in this survival group is a familiar friend before. If anyone is gone because of this disaster, it is undoubtedly a unpleasant thing.

What's more, it's not the peaceful environment in the past. Just after the world-class disaster, there are some people in our hearts.

This kind of time can meet familiar people or things, for all people, although not necessarily can play a big role, but more or less can bring some spiritual comfort, let everyone in the land after this disaster more can let themselves support things.

In the exchange of needs, Chen Xin also learned about the current situation.

Because we had made full preparations, accumulated enough materials, and built our own shelters. Everyone in the previous survival group is now in their own shelters, successfully avoiding the previous disaster. Some group friends with good conditions even have enough to accept others.

However, although we all survived and relatively well off, the problem is not without.

Although most of the group friends have shelters and relatively sufficient supplies, many of them have the same problem as before, that is, lack of domestic water.

Although we can rely on the water circulation device for a while, but in the long run, it is bound to fall into the situation of no water available.

Chen Xin has nothing to do with this problem. Instead, the "drilling expert" in the group proposed to drill wells to solve the water supply problem.

On the one hand, this proposal is because all the refuges are built underground, and there are difficulties in construction. On the other hand, it is also because the "drilling master" is a friend of the city, and it will not play any role for a while and a half.

Fortunately, although there is a lack of domestic water, this problem is not serious. At present, we are living a tight life and need to pay great attention to water conservation.

"If there is a shortage of water, well drilling can solve the problem. Even if the construction is not good indoors, well drilling can be done outdoors, and then pipes can be connected indoors. I've done this job, and it's not difficult."

In the communication channel, "drilling master" provides solutions to the water shortage shelters with his own professional knowledge, and he also says that if you need, he can bring people from Linshi to help solve the water shortage problems.

Just waiting for him to come from Linshi is not something that can be done in a short time.

"You'd better not come here. No one knows what's going on on the road now. For safety's sake, let's try our best." Mo Qingyan heard "drilling master" said to bring people to come, immediately out of a voice to stop him.

When the meteorite fell down before, Yanguo was not the main disaster area, but there were still a lot of meteorite debris smashed down. No one knows whether it caused road damage.

And even if the road is smooth, if you want to come from the city, there is still a great risk.

So after a while of discussion, it was mo Qingyan who suggested that we should provide help from this side of the city for those shelters that are short of water.

At least she can borrow the sprinkler used for municipal greening through the special police team, and use the water tank of the sprinkler to help these shelters replenish fresh water.

After all, we all have water circulation devices in our shelters to replenish fresh water for a long time.

"Let's deal with it like this first. Ah Ning and I will go to see Uncle Ding and contact the municipal government to see if we can help solve this problem." Mo Qingyan said on the communication channel that at this stage, the government is still the first choice trusted by everyone.

In the face of disasters, the way the government has been dealing with has established a strong credibility in the hearts of the people. Even now is the end of the world, before the government collapses or loses credibility, people are still willing to believe in the government.

After everyone finished these things, Chen Xin proposed to Mo Qingyan that he wanted to change materials.

"How big is your greenhouse? How can we exchange so many vegetables for materials? " When Chen Xin heard that he wanted to exchange materials, it was not Mo Qingyan who was the first to speak, but a group of friends called "old farmers of farming land".

Because he is a farmer, and also engaged in hydroponic cultivation, he knows how many crops can be produced by greenhouse cultivation.

Because of this, he was very surprised that Chen Xin needed to exchange so many materials, because he simply estimated that Chen Xin needed at least half an acre of land to produce so many vegetables in two months.

"I've dug 200 square meters for the greenhouse, but now I plan to expand it, add hydroponic planting plates, and store some materials, so that in case there is any damage to the shelter or the place needs to be expanded in the future, there won't be no resources." Chen Xin concealed the current situation of his greenhouse, just a simple explanation.Because she had changed vegetables from Chen Xin once, Mo Qingyan also knew that he could get the promised things, so she didn't ask much, and agreed happily: "it should be no problem. When ah Ning and I go back to find uncle Ding, we will tell him that you can provide so many vegetables, uncle Ding will surely be willing to exchange with you."

"I'll trouble you, long Niang." Chen Xin sincerely asks Mo Qingyan.

"It's a small matter. You can just give me more vegetables." Mo Qingyan quite forthright response way.

Having said these things, Chen Xin just ended his conversation with others and turned off his radio station.

Mo Qingyan promised to help, which undoubtedly relieved Chen Xin a lot. As long as this can be done, the upgrading speed of his refuge will undoubtedly be greatly improved.

As long as this channel can be stabilized and vegetables can be exchanged for materials every month, Chen Xin can save a lot of survival and greatly improve the speed of upgrading the refuge.

After all, this time he exchanged materials according to the maximum material demand given by the system.

According to the rules of the system, as long as he can provide all the materials according to the requirements given by the system, the survival needed in the upgrade is only one tenth of the original.

Just like the planting greenhouse that Chen Xin plans to upgrade now, if he only uses survival upgrade, the two upgrade schemes need 2000 points and 3500 points respectively to complete the upgrade.

But now Chen Xin is able to provide all the materials required by the two upgrading schemes, and his survival point for upgrading has been reduced to 400 points, which is because he has chosen two upgrading schemes at the same time.

The same is true for other upgrade projects. As long as Chen Xin can provide enough materials, the upgrade points can be directly cut to zero.
