Climbing up to the location of the observation room, Chen Xin wanted to take a good look at the upgraded observation room.

From the outside, the upgraded observation room looks like a flat canned box embedded in the mountain, covered in snow, and inconspicuous in the pitch black.

Facing the gate of the shelter is the observation port, which is still not wide, only enough to look out from the inside, making the entire observation room look like a common machine gun bunker in war movies, the only thing missing is that Chen Xin did not put a heavy machine gun in it.

The vents that were moved to the exterior wall of the "bunker" were shuttered, and the air that was expelled from the inside of the shelter would be cooler and cooler through the cooler pipes in the observation wall before exiting through the vents on one side of the façade.

This structural design makes the problem of icing no longer a problem for Chen Xin, there is no air with water vapor sprayed from the inside, and the observation port will no longer be sealed by condensed ice, and Chen Xin naturally eliminates the heavy daily de-icing work, and does not need to hold a small hammer to smash ice cubes every day.

Chen Xin was satisfied with the upgraded observation room, but in addition to being satisfied that he would not have to do de-icing work in the future, Chen Xin did realize that his physical fitness was insufficient and that his protective clothing was still defective.

His physical fitness is insufficient, which is the result of a lack of exercise, although Chen Xin's physical condition is much better than in the past few months because of farm work, and his physical fitness is also at the level of ordinary normal people, but he is still not strong.

So exercising, it's an option to be included in your plan.

In the previous days in the shelter of the SWAT team, after Chen Xin finished eating at night, because he was idle and had nothing to do, he was taken by Qin Lan to the gym of the SWAT team to exercise.

In addition to making Chen Xin's muscles a little sore for a few days, it also made him realize that his shelter might also be able to add a gym.

After all, it's a great way to exercise and pass the free time every night without having to play games every night.

It's not that playing games is not good, it's just that exercising is better for your health than playing games.

And Chen Xin's evening time is actually relatively abundant, and he can exercise his body for an hour and then play a game for an hour, and there will be no problem of choosing one or the other.

Adding a gym isn't complicated, and it doesn't have to be a separate room, just add some gym equipment to the living room and work out after dinner in the evening.

This doesn't even require Chen Xin to consume precious survival points, he only needs to get a set of fitness equipment, and it's not impossible to even make do it himself.

With a decision in his heart, Chen Xin naturally included this matter in his plan and recorded it in what he was going to do next.

In addition, the re-upgrading of protective clothing is another thing that Chen Xin recorded in his plan list.

There is no problem with the performance of the protective clothing itself, and the anti-corrosion and thermal insulation effect has been very good, but as the temperature drops, the protective clothing needs to deal with not corrosive acid rain, but the severe cold caused by low temperature and strong winds, and the low oxygen environment after the oxygen content is reduced.

Although it is not a big problem not to adjust, Chen Xin still hopes to add an oxygen supply function to the protective clothing, so that the next time he does physical labor outside, he will not feel difficult to breathe after working for a while.

And the protective clothing itself also needs to be adjusted, although the previous long hem is good in rain and warmth, but wearing physical labor will find that long coats are still not convenient for labor, relatively speaking, short ones are more suitable.

Therefore, the adjustment and transformation of protective clothing was naturally included in the transformation plan by Chen Xin.

In addition to these two things, the ground source heat pump promised to Li Wensheng, Mo Qingyan and other friends will also be made, and the upland rice that will mature this month in the planting greenhouse will also be harvested, as well as the matter on Li Yulong's side......

After counting it carefully, Chen Xin found that he had a lot to do this month.

Fortunately, most of the things are not very urgent, and after listing them one by one and planning them, if you do them according to the planned schedule, you can still get everything done.

The transformation of the protective clothing and the gym are not urgent, and it is okay to do it again when there is time, but to promise Li Wensheng the ground source heat pump, Chen Xin needs to make it as soon as possible, so as to reach a deal with him in exchange for the aquaponics equipment he wants.

After all, this matter had been told to others before, but he went to the official shelter in the past few days, and it is estimated that Li Wensheng can't wait for the past few days.

Because Qin Lan is no longer there, when Chen Xin made the ground source heat pump again, it was not as slow as when she was there.

Directly dismantling an air conditioner with the system, then assembling the various parts and upgrading it again, Chen Xin, who is already a skilled worker, only took more than an hour to build a new ground source heat pump.

Of course, this ground source heat pump is different from the one Chen Xin himself uses, and no steam turbine generator is added.

The finished equipment was left on the ground next to the workbench, and Chen Xin did not immediately start making the second equipment.

So far, in addition to the one he promised to Li Wensheng, only the equipment promised to Mo Qingyan needs to be made, and other group members also want ground source heat pumps, but Chen Xin, who is not at home these days, has not received new orders, so naturally there is no need to produce new equipment.

As for the equipment that he wanted to give to Mo Qingyan, because Chen Xin wanted to add a steam turbine generator and aquaponics equipment to it, Chen Xin couldn't make it before Li Wensheng sent the aquaponics equipment he promised.

Therefore, after completing the ground source heat pump for Li Wensheng, Chen Xin had no orders to do.

But this does not mean that he is idle, the planting greenhouse that has not been taken care of for a few days needs to be taken care of, and the upland rice that has been filled and matured is waiting to be harvested, and he has to be ready for harvesting.

Although he doesn't grow a lot of upland rice, if he cuts it manually, Chen Xin feels that with his own efficiency, he may not be able to cut it in one day, and cutting rice is a very tiring job.

Fortunately, in exchange for small agricultural machinery, Chen Xin can use a small harvester to harvest, instead of cutting rice manually.

Of course, before he officially starts harvesting, he also needs to check the small harvester that he has never used before, and understand how to use it, so as not to cause any problems due to improper use.
