Doomsday Bunker Upgrade

"I can upgrade the shelter ( to find the latest chapter!

After being comforted by Qin Lan, Chen Xin didn't say anything, but he still planned for the worst.

Optimism is needed, but preparing for the worst is also needed.

In other words, if you plan for the worst, you can face it optimistically and positively no matter what happens, because the situation can't get worse.

For Chen Xin now, the worst case...

That is, another geological movement occurred, causing the deep groundwater layer to lose pressure, and affecting the shallow groundwater layer, causing the shallow groundwater to flow into the deep groundwater layer, and finally there was no groundwater available here.

Although this is a very extreme situation, in terms of geology, it is not impossible for the groundwater layer to be cut off due to geological activities.

Judging from the current situation of Chen Xin, if the groundwater layer is cut off, he will face the dilemma of water shortage again.

Although he can use the vegetables grown in the greenhouse in exchange for drinking water, there is a big problem here is that crop cultivation requires a lot of water resources.

In addition, the grown vegetables contain a lot of water, which will not enter the circulation system inside the refuge for recycling.

Therefore, if this happens, Chen Xin must find a way to obtain a new source of water. As for moving, it is the ultimate choice in desperation.

Fortunately, there is a lot of snow outside, and snow is still happening from time to time. Collecting the melted snow and using it as water is a good way.

However, the snow outside is very dirty, and the collected snow needs to be purified and filtered.

In addition, upgrading the water circulation system to make the wells that were originally system upgrades deeper, the pump lifts larger, who can be pumped out of the deeper stratum, is also a solution to the problem once and for all.

After reviewing the coping methods he could make in his mind, Chen Xin became more at ease about the worst possible situation, at least he had enough means to deal with it.

This made his mood naturally a lot more optimistic, and he smiled at Qin Lan: "Okay, the generator is installed, and then continue to build the ground source heat pump. Only the equipment your SWAT team needs has been built. There are five more stations to rush to work, and I don’t know if they can finish it in two days.

"Axin, your technology is so good, you can definitely finish it on time, and I will help." After seeing Chen Xin's "process" for manufacturing these machinery and equipment, Qin Lan has full confidence in Chen Xin.

"That's okay, Alan, you help me take the parts that were cleaned yesterday..." Chen Xinzheng was about to ask Qin Lan to take the parts that were washed yesterday to dry, but the radio in the living room suddenly rang and a call came out. the sound of.

Qin Lan and Chen Xin turned their heads to look at the living room, and couldn't help but be surprised: "Is someone calling you?"

"Well, let me see what's going on, Alan, take out the parts cleaned yesterday and dry them with water." Chen Xin gave Qin Lan a command and walked towards the living room.

Picking up the shortwave radio's talker, Chen Xin responded to the call. After a conversation, Chen Xin responded that another group of friends came to him to exchange ground source heat pump equipment.

After talking to Qin Lan, Chen Xin took the gun and walked towards the entrance of the refuge, and Qin Lan quickly put down his work and followed Chen Xin.

Putting on protective equipment in the preparation room, Chen Xin still went through the passage to the small bunker first, looked out through the observation port, and wanted to see who was coming.

However, the car parked at the door of his refuge surprised him.

It was an eight-wheeled truck that looked like a heavy-duty truck. Eight huge tires that were one meter high made this car still walking on the ground even in the thick snow.

But it is different from a truck. Instead, it has a sturdy and thick carriage like an armored car, and the windows on the carriage also show light from the inside of the carriage, illuminating a black and red moire dragon head pattern on the car body in the darkness. .

There is no need to identify carefully, just these conspicuous features are enough to make Chen Xin recognize that this is a modified RV and understand who its owner is.

"Alan, don't go out first." After Chen Xin nodded to Qin Lan since he was a little bunker, he opened the door of the refuge.

Qin Lan watched Chen Xin push through the door of the refuge and walk out. She suddenly became nervous, and the gun at her waist was also caught in her hand, ready to rush out at any time.

Chen Xin walked out the door of the refuge, seeing that the other party hadn't turned off the headlights, the lights made him a little dazzling.

So he lifted the bright flashlight in his hand and shone it directly at the cab of the car in front of him, dazzling the driver's eyes with the flashlight.

Obviously the opponent was also dazzled by Chen Xinhuang, and soon turned the headlights into low beams, and jumped out of the car.

However, the cab of this car was obviously a bit high. After the opponent jumped down, his legs were directly inserted into the snow.

"Brother Chen~www.ltnovel.com~ Why is the snow so deep at your door!" The man who got off the car pulled out his legs from the snow, and then walked deep and shallow to Chen. New front.

Looking at the figure walking in front of him, Chen Xin smiled and said, "How deep is the snow, don't you feel any sense when you drive over from the city? And how many times have I said you, don't always go down from the cab Jump, you are not afraid of breaking your leg?"

"I'm used to it, let's say, driving this kind of high-chassis car, who is impatient to climb down!" Although the figure wears a protective mask on his face, the voice of a hippie smiling face suddenly makes people recognize his youth. .

Chen Xin and this person are naturally acquainted, otherwise the other party should call him a writer instead of what a familiar person like Xiao Chen would call him.

"Xiaolong, why are you looking for me? You don't want to change the ground source heat pump?" Chen Xin wanted to laugh every time he called the person in front of him, Xiaolong, because his surname was Li: "Do you still need a refuge in your house? Are these?"

"Why don't you need it anymore?" The man immediately retorted Chen Xin's words, and said anxiously: "My refuge is equipped with an air conditioner. It used to be fine when there was electricity, but now there is no electricity, and I rely on my own electricity This air conditioner can't be used!"

Hearing this, Chen Xin could understand what the other party was doing, so he nodded and said, "That's fine, but you also understand the rules. Did you bring both materials and exchanged goods?"

"Brother Xiao Chen, don't you know me? When did Li Yulong not work reliably?" Li Yulong immediately patted his chest, with a confident look: "According to you, two air-conditioning external units It's the ingredients, and I also brought you a cured ham and two boxes of individual rations.

Ham I originally wanted to take Iberian ham, but my dad refused to let it go, so I took a piece of Jinhua ham. Don't dislike Xiao Chen. "
