Doomsday Bunker Upgrade

Of course Chen Xin is not an irresponsible person, but in this situation, he really can't make any promises to Mo Qingyan.

In fact, there is no need for any commitment between him and Mo Qingyan. What he needs to give Mo Qingyan is only emotional recognition and the transformation of the relationship, from being a good brother to a couple.

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

Chen Xin has never had the experience of socializing with 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 somewhat at a loss as to 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 of Qin Lan, Chen Xin fled his RV with some embarrassment and returned to the construction site.

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

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

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

After all, even if Qin Lan had already reached an agreement with Mo Qingyan, the relationship between the three of them was very good before, but neither Chen Xin nor Qin Lan and Mo Qingyan had imagined that the relationship between the three would become like this.

So it is not just Chen Xin who needs time to adapt and adjust, they also do the same.

After returning to the construction site, Chen Xin quickly returned his energy to his work. Although he had just experienced the changes that had a major impact on his life, he still needed to earnestly complete his work.

The workers who went home for the New Year holiday yesterday have already returned to the construction site early in the morning, and are working energetically at this time.

Chen Xin put on his own power armor and went down to the bottom of the snow pit. At this time, 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 heat sinks must be installed inside, making the entire heating hub look like a building after completion. The same as the iron tower.

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

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

Chen Xin had already expected this situation. After all, the low temperature of tens of degrees below zero, the cold has already frozen the ground hard, even the ice layer formed by the condensation of snow next to it is as hard as granite. For the hard concrete floor, it is not an easy task to make large enough holes in the ground to serve as the foundation of the heating hub.

However, Chen Xin obviously wouldn't just watch the workers slowly smash the floor with time and effort. Chen Xin with power armor was enough to easily break through the cement on the ground and punch holes that met the requirements of the design drawings.

"Get out, let me come." Chen Xin said to the workers. After they stopped work and got out of the way, they squatted down and controlled the mechanical arm to aim at the position where the worker had just used a pneumatic pick.

It was hit by a worker with a pneumatic pick just now, but there were only a few white spots on the ground, and there was no sign of breaking.

Obviously, the freezing caused by the cold makes these already solid cements stronger and harder to penetrate.

It's just that this didn't have much effect in front of Chen Xin's mechanical arm. As the various tools on the mechanical arm worked together, Chen Xin soon directly cut a piece of cement on the ground.

Although the cement is so hard that it cannot be broken with a pneumatic pick, this does not mean that it can withstand the cutting of the 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 is 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 compacted.

If only this is the case, letting the workers dig with a **** would be the end, but the cold and low temperature turned the soil into frozen soil, which is not something that can be digged casually by humans.

In fact, Chen Xin asked the workers to give it a try. Even with a pneumatic pick, it was just a small pit in the gravel frozen soil. Although it is not useless, if you want to lean on the ground with the pick It will take a long time for UU to read www.uukanshu.com to build the foundation that Chen Xin needs.

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

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

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

Although the workers were amazed at the efficiency of Chen Xin's power armor, they could only envy them. It was their turn to work on their own, and they could still only use their hard-working hands.

The main support columns of the heating hub were buried in the just laid foundation according to the requirements marked by Chen Xin on the drawings, and other support parts were assembled according to the drawings, and the main support columns were fixed and kept horizontal and vertical. After that, 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, it is necessary to raise the temperature above zero. For Chen Xin and others, there is no such construction yet. condition.

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

These workers are all skilled workers, so there is no problem in this step. All the support columns have been very smoothly completed in accordance with the construction requirements.

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