After upgrading the power armor, Chen Xin and Qin Lan rushed back to the city.

Originally, Han Ping and Han Ze wanted to follow Chen Xin together. Han Ping was Chen Xin's bodyguard, so there was no reason not to follow Chen Xin, and Han Ze was called together by Han Ping to fight for Chen Xin's work.

However, Chen Xin rejected the proposal of the two brothers and kept them in his own shelter, with very sufficient reasons.

"My parents and two friends live here. They need someone to protect them. Han Ping, since you are my bodyguard, then protect my family. If I have this set of power armor, no one can hurt me." Chen Xin said to Han Ping, who wanted to go to the city with him.

Faced with Chen Xin's full reason, Han Ping could only continue to stay in the shelter and be responsible for protecting Chen Xin's parents and Mo Qingyan's sisters.

Chen Xin and Qin Lan once again crossed the blizzard and returned to the city.

However, this time they did not go to the Municipal Police Department or the Institute of Technology, but went to a small refuge divided by the city government as an isotope temperature difference battery production line.

The city government has obviously sent someone to clean up the place. Although in a low temperature environment of more than minus 70 degrees Celsius, even if the heating boiler has been turned on, it is so cold that it makes people shivering, and even splashing water into ice.

However, with the mobilization of the city government and the situation in various shelters has improved slightly, there are still enough people to clean up the place and start to tear down some partition walls according to Chen Xin's previous requirements.

These partition walls were all partition walls installed before the disaster to divide the internal space of the shelter. Some of them were just ordinary lightweight partition walls, which could be easily removed by just removing the fixed buckles, but some were brick walls that served as supportive functions, and this part was difficult to remove.

Even under normal circumstances, it takes some effort to remove a brick wall. Now, at a low temperature of tens of degrees below zero, even the soil can freeze harder than granite. A hammer will only leave a white mark if it hits it. In this case, it is not something that a sledgehammer can handle.

After arriving here in power armor, Chen Xin also tried to use power armor to remove a brick wall. As a result, with power armor, he could use power armor to exert more than 1.25 tons of force, and hit the brick wall, but it was just a hole.

This also slightly deformed the mechanical structure of the power armor hand. Obviously, this type of hard object with the maximum output still damages the mechanical structure of the power armor.

However, this is obviously not the correct use of power armor. Although this is OK, just like anyone with a brain will choose to smash the wall with a hammer instead of using his hands, power armor can smash the wall with a punch, but there is no need.

After activating the robotic arm on his back, Chen Xin controlled the steel hand to switch to the appropriate tool, and then followed the place he had just smashed with a punch, and easily expanded the big hole of the fist, and the more it was dismantled, it quickly dismantled a large hole that was one person tall.

Such efficiency is undoubtedly amazing, but it is the performance of power armor.

Qin Lan asked the worker to borrow an iron hammer, held it with one hand and swung it directly on the wall. After a few rounds, he successfully smashed the other wall into a sunken, kicking it up and a big hole.

Such efficient wall demolition speed is of course faster than that of workers who swung their hammers to smash the wall. In fact, even if the brick wall was half-demolished by Chen Xin and Qin Lan, it would be very difficult for workers to demolish it. Usually, it took a long time to demolish the bricks, and the progress was quite slow.

But even so, Chen Xin and Qin Lan did not use power armor to help demolish the walls, but instead found the construction manager and confirmed the structure of the shelter with the other party.

Although it has been confirmed here as a production line for isotope temperature difference batteries, the specific construction drawings of the production line have not been released yet, because the drawings themselves need to be modified according to the structure of the site. Although under normal circumstances, the factory is built according to the equipment requirements, some equipment needs to be installed according to the site.

So this is not a strange thing, not to mention that although the venue and other things have been prepared, in fact, because there is no precedent to refer to, the production line is just the idea in Chen Xin's mind and has not been turned into a finished product at all.

Of course, this is not a problem for Chen Xin at all. Having an idea is enough to use the system upgrade function to upgrade the production line.

According to Chen Xin's idea, the entire production line should include raw material processing, metal parts casting, radioactive charge processing, high-precision parts production and other aspects, and finally gathered on the assembly line.

Among them, the more difficult parts are the casting of metal parts and the processing of radioactive charges.

Metal parts casting is mainly used for radiation isolation inside the battery to ensure that the radiation released by the radioisotopes inside the battery will not be leaked. Therefore, this part will use lead alloy as a material for high-precision overall casting.

The most critical issue in casting parts is that it requires a high-temperature furnace to melt the material into a meltable castable state.

Of course, it is not impossible to use stamping and molding to make it, but in this environment, it is obviously not suitable to use a water press, but a furnace is more suitable.

Fortunately, since the isotope generator has been made, it is enough to cover the electricity demand of the electric furnace and there is no need to worry about energy.

The energy consumption of electric furnaces is easy to solve, but the heat released by this thing during work is not so easy to solve. After all, it is in a closed underground, and various problems caused by the use of furnaces need to be considered.

The oxygen consumed during the furnace operation, the high temperature released, the precise temperature control environment required during cooling are not something that can be decided easily. If Chen Xin does not have a system and wants to arrange these things, it requires detailed argumentation and calculation, and the final result can only be achieved before the furnace installation can be prepared.

As for radioactive charge processing, this is better than a furnace. As long as radiation prevention measures are taken, even the country can process the radioactive isotopes used as raw materials in other places and deliver them. Only the loading is required here is the whole thing.

Although radiation prevention is difficult to do, considering that this production line can basically be exposed to radiation in every link except for the initial raw material processing, the entire small shelter is a place where radiation protection is required throughout the process. This can only be regarded as a hard requirement, and there is no need for additional calculations and arrangements.
