Doomsday Bunker Upgrade

Chen Xin is of course not an irresponsible person, but under the current situation, he really can't make any promises to Mo Qingyan.

In fact, he and Mo Qingyan didn't need any commitment. All he needed to give Mo Qingyan was emotional recognition and a change in relationship, from being a good brother to a couple.

As for what really matters is how to deal with the relationship between him and the two women in the future.

Chen Xin has never had the experience of dating two girls at the same time, and also never thought that he would sleep in the same bed with Qin Lan and Mo Qingyan at the same time.

This made him a little confused about the new relationship between the three at this moment.

So after saying some comforting words to Mo Qingyan, and at the same time agreeing to some unequal treaties from Qin Lan, Chen Xin fled his RV with a bit of embarrassment and returned to the construction site.

Qin Lan and Mo Qingyan couldn't help but feel a little bit angry about Chen Xin's escape. After all, no woman would hope that the man would run away on the first day of their relationship.

However, they all expressed their understanding generously, and were willing to give Chen Xin and themselves some time to adapt to the change in the relationship between the three.

To be honest, for Qin Lan and Mo Qingyan, it does take time to adapt to this change in the relationship between the three.

After all, even though Qin Lan had already reached an agreement with Mo Qingyan, the three of them had a very good relationship before, but neither Chen Xin nor Qin Lan and Mo Qingyan ever imagined that the relationship between the three would become what it is now.

So it's not just Chen Xin that needs time to adapt and adjust, but they too.

After returning to the construction site, Chen Xin quickly put his energy back to work. Although he has just experienced changes that have had a major impact on his life, the work still needs him to be completed seriously.

The workers who went home from vacation yesterday for the Chinese New Year had already returned to the construction site early in the morning, and they were working full of energy at this time.

Chen Xin put on his power armor and went down to the bottom of the snow pit. At this time, he saw that the workers were demolishing the exposed concrete floor under the ground, preparing to lay the foundation for the heating hub.

The entire heating hub is more than ten meters high, which is almost equivalent to a four- or five-story building. A complete set of evaporative cooling devices must be installed inside, making the completed heating hub look like a built-up building. Same as the tower.

Of course, the current heating hub is just a bunch of parts that have not been assembled yet, and it needs workers to assemble it bit by bit after laying the foundation.

Chen Xin, who went down to the bottom of the snow pit, saw that the workers were hitting the cement on the ground with an air pick, but the effect was not good, and the construction progress was not ideal.

Chen Xinzao had expected this kind of situation. After all, the low temperature of minus tens of degrees has already frozen the ground hard. Even the ice layer formed by the condensed snow next to it is as hard as granite. It is not an easy task in itself to make holes large enough in the ground to serve as the foundation of the heating hub.

However, Chen Xin obviously won't just watch the workers smashing the floor slowly and laboriously. With the power armor, Chen Xin can easily break the cement on the ground and punch holes that meet the requirements of the design drawings.

"Get out of the way, let me come." Chen Xin said to the workers, and after telling them to stop working and move out of the way, he squatted down, and controlled the robotic arm to aim at the position where the worker had just used the pick to break it down.

This place was hit by a worker with an air pick just now, but there were only a few white spots left on the ground, and there was no sign of it breaking.

Obviously, the freezing brought by the cold has made these solid cements stronger and harder to penetrate.

It's just that this has no effect in front of Chen Xin's robotic arm. With the various tools on the robotic arm working together, Chen Xin soon cut a piece of cement off the ground.

Although cement is very hard and cannot be broken with an air pick, this does not mean that it can withstand cutting by a cutter.

After cutting the cement, it does not mean that the work becomes easier, it can only be said that it is relatively less difficult to handle.

Because under the cement are gravel and soil. These are the foundations that were filled when the square was built in the past, and they were also pressed by a road roller. While ensuring the ground is level, the soil and gravel below are also pressed more tightly.

If that were the case, it would be enough for workers to dig with a hoe, but the cold low temperature turned the soil into frozen soil, which is not something that can be dug casually by manpower.

In fact, Chen Xin asked the workers to try it out. Even with the air pick, it just made a small pit on the gravel and frozen soil. Although it is not useless, if you want to rely on the air pick to hit the ground on the ground It will take a long time to lay the foundation that Chen Xin needs.

Faced with this situation, Chen Xin could only continue to wave his mechanical arm.

As a result, in the surprised eyes of the workers, Chen Xin's robotic arm built all the foundations needed for the construction of the heating hub on the ground with an efficiency nearly ten times faster than theirs.

"Okay, the foundation has been laid, and the next construction will be handed over to you." Chen Xin stood up from the ground, feeling a little sore in his waist, so he told the workers and asked them to continue the construction. Just climbed out of the snow pit.

Although the workers were very surprised at the efficiency of Chen Xin's power armor, they could only be envious. When it was their turn to work, they could only use their hard-working hands.

Several main support columns of the heating hub were buried in the foundation just laid according to the requirements marked by Chen Xin on the drawings, other support members were assembled according to the drawings, and several main support columns were fixed and kept horizontal and vertical. After that, the cement was poured into the foundation.

Of course, the cement used by the workers is no longer the ordinary cement in the past. Although that kind of cement is not unusable, the temperature must be raised to above zero. For Chen Xin and the others, there is no such construction for the time being. condition.

Therefore, they use antifreeze cement with antifreeze and water reducing agent added to ensure that the cement will not freeze due to the rapid condensation of water during use, resulting in cavities and other phenomena in the cement.

These workers are all skilled workers, so there is no problem in this step, and all the support columns have completed the pouring of cement according to the construction requirements.

And because the weather was too cold, the cement soon became as hard as a stone, firmly fixing the support columns of the heating hub to the ground.

The new year is over, and the normal update will resume from today
