Doomsday Bunker Upgrade

"Simple Ground Source Heat Pump"

"Upgrade plan 1: Replace the circulating medium, improve the heat exchange efficiency of the equipment medium, and upgrade the required survival points by 300"

"Upgrade plan 2: Replace the circulating medium, improve the equipment medium circulating efficiency, and upgrade the required survival points by 500"

The ground source heat pump equipment that Chen Xin assembled is still an ugly guy, but compared to the pile of things that were put together when the oxygen generator was first made, this ground source heat pump equipment at least looks like that, and it doesn't look too much. Shabby and shoddy.

Seeing the upgrade plan displayed by the system, Chen Xin just raised his eyebrows and clicked to confirm the upgrade, and applied both upgrade plans to this ground source heat pump equipment.

The green light is still flashing, the whole ground source heat pump equipment seems to be reborn, and the size and structure of the equipment itself have also changed.

In general, things get bigger, pipes get thicker, and the structure gets more complicated.

Or it can be said that what Chen Xin just made is just something that can barely be called a ground source heat pump, and the upgraded one is the real ground source heat pump equipment.

But looking at the pile of pipes lying on the ground, Chen Xin couldn't help scratching his head. Qin Lan's drill bit had not been delivered yet, how would he install this thing into the ground?

The pipeline part of the ground source heat pump equipment is a very large structure, although because the equipment is still not installed, a large number of pipelines are just stacked together.

But looking at the pile of pipes, Chen Xin still felt a headache. It was a little different from what he expected. These pipes were assembled like a huge radiator. !

Just when Chen Xin felt embarrassed, the system once again showed a sense of existence.

"Consume 50 Survival Points to install a Ground Source Heat Pump?"

Looking at the system prompt that appeared in front of him, Chen Xin scratched his chin, and some unshaven beards could not help but prick his hands, but that's not the point.

"Is the system so powerful? It's really possible to do whatever you want if you have a survival point!" Chen Xin rubbed his chin. Although he already knew the power of the system, he still felt that he still hadn't fully integrated the system. function out.

He also thought about installing the equipment through the system before, but Chen Xin planned to put the ground source heat pump he assembled into the planting greenhouse. After pretending to be installed, he would use the power of system upgrades to install the equipment in place.

Instead of the current situation, the equipment is placed here, and the equipment is installed in place with a single click of the system.

However, since it has such a convenient function, Chen Xin did not bother himself, and chose to consume survival points to allow the system to install.

As for the installation location of this equipment, Chen Xin chose it next to the wall in the public space near the planting greenhouse, and connected a radiator to the planting greenhouse.

The installation interface of the system is somewhat similar to the placement interface of some management and construction games, which is a green grid-like virtual interface.

Chen Xin tried it. In this interface, he can move or adjust the structure of the shelter and the placement of items at will. It is completely controlled by his mind and does not require his additional operations.

Through this interface, Chen Xin can adjust the building structure and the position of items that he finds dissatisfied or inconvenient in the shelter, and can even enlarge or reduce the area of ​​the room, and even divide the function, which is very convenient and powerful.

Of course, such a convenient and easy-to-use function is naturally based on the consumption of survival points.

Chen Xin just adjusted and moved a few rooms and changed the position of the equipment. In the interface displayed by the system, the survival points required to achieve these changes exceeded 1,000 points.

Looking at the numbers displayed by the system, Chen Xin could only obediently give up his idea of ​​adjusting the building structure and equipment placement of the shelter, and closed the interface only after installing the ground source heat pump.

Obviously, this interface is not something that Chen Xin can afford now.

After installing the ground source heat pump equipment, looking at the ground source heat pump occupying a considerable part of the public space, Chen Xin felt that perhaps he should upgrade the shelter as a whole as soon as possible, or save enough survival points to make a difference to the building structure of the shelter. There are equipment placement adjustments.

Otherwise, he felt that his shelter would only get more and more crowded.

After installing the ground source heat pump in place and turning it on, Chen Xin soon felt the heat dissipating beside its radiator.

The temperature was set to 20°C on the control panel of the ground source heat pump equipment, and after checking it again, seeing that the equipment was running normally, Chen Xin took out today's dinner from the newly added food storage room and prepared to eat.

What Chen Xin ate today was very simple, just a shelter ration and a can of luncheon meat.

Chen Xin simply fryed the luncheon meat, put the shelter rations in a pot and heated it, then sat on the sofa with the pot and started to eat.

After being so busy, Chen Xin still felt exhausted even though the system helped save a lot of effort.

Eating slightly rough food, Chen Xin missed the sweet and sour pork ribs made by his mother for no reason.

That is Chen Xin’s favorite dish since he was a child. The fresh and tender pork ribs are cut into sections and then deep-fried. They are cooked in sweet and sour sauce. …

When Chen Xin was young, even if there was no meat and only a bowl of mushy bibimbap, Chen Xin could eat a bowl of rice.

Thinking about it, Chen Xin's eyes couldn't help shedding tears, which dripped into the meal.

His mother is far away from his hometown at the moment, separated by a distance of more than 600 kilometers, across the four provinces of Hunan, Hubei, Anhui, and Jiangxi. If there is no systematic existence, Chen Xin is afraid that it would be an extravagant hope to see his mother again in this life.

Although Chen Xin forced himself not to think about this, the tears couldn't stop flowing, and the thoughts of his mother couldn't stop pouring out.

His parents are too far away, even if there is a radio, Chen Xin can't talk to them, and his hope of seeing them again in this life is slim.

The spoon in his hand was like a thousand pieces, and Chen Xin couldn't lift his hand holding the spoon, and put the mouthful of food that was so close at hand into his mouth.

At this moment, what he was thinking about was not about eating, but about whether his parents, who were more than 600 kilometers away, more than 1,200 miles away, were all right.

The unstoppable longing made Chen Xin simply throw down the spoon in his hand, grab a piece of toilet paper and wipe the tears on his face carelessly, and came to the bedroom to flip out the album that was originally locked in the box.
