Going back to his hometown to pick up his parents is the most urgent thing for Chen Xin at the moment.

Originally, the lack of suitable transportation was the biggest obstacle to him doing this, but now that the car has been transformed, this matter has been put on the agenda and has become something that Chen Xin is about to do.

It's just that no matter how urgent his mood is, it's still not a trip to go.

Although he now has transportation, the road is long, water and food must be prepared, and other related supplies are also necessary, after all, he does not know what is going on with his parents.

Before the disaster, Chen Xin's last news was that his parents and relatives had moved into the village shelter.

All the people in that village are relatives in the family, and Chen Xin has been giving them ideas since the construction of the shelter, all kinds of precautions and the construction of survival facilities, Chen Xin has prepared for himself, so he told them what to prepare.

Therefore, the living conditions of the shelter in that mountain village are not bad, and there is almost no difference from the shelter before Chen Xin did not upgrade the system, and even because the area is large enough, it may be more comfortable to live in.

Therefore, Chen Xin is not worried about any danger or trouble for his parents and relatives at home, the village is still more than ten miles away from the nearest town, and even an hour's drive from the county seat, and no one will be interested in such a poor and remote mountain village.

But having said that, no one can predict what will happen, and the closed environment in the mountains not only eliminates outside interference, but also brings great inconvenience to the contact between the mountain village shelter and the outside world.

After all, there are more than ten miles of road in the nearest town, Duli Village, and the mountain road itself is not easy to walk, and it is not easy to enter the mountain under the condition of heavy snow closing the mountain, and it is very difficult for people in the mountains to come out.

If something happens in the mountains, whether it's coming out to ask for help or going in to help, it's a very difficult thing.

Although Chen Xin didn't think anything big would happen to the mountain village shelter, he had no guarantee that there would be no accident.

In order to deal with the eventuality, Chen Xin had to be well prepared before he could set off.

On this road of more than 600 kilometers, no one knows what kind of situation will be encountered, and it is difficult to say whether he can encounter a shelter on the road, and Chen Xin must prepare for the worst.

The more than 600-kilometer-long journey refers to the highway before the disaster, which used to rely on the service area for rest and supplies, but in this case, it is very likely that there will not even be a shelter along the way, unless Chen Xin specifically enters the city.

If he can't resupply or encounters a shelter along the way, he should at least have enough supplies in the car to consume along the way.

Thinking of the supplies, Chen Xin couldn't help but ask Qin Lan: "Ah Lan, so many things have happened in the urban area, can the SWAT team still come to exchange materials this month?" ”

"It should be possible, although there have been a lot of things recently, but the matter of material exchange itself should not be affected, that is, the materials used for exchange may be relatively unsatisfactory." Qin Lan thought about it for a while, and felt that there should be no obstacle to this matter, and the exchange of materials could be carried out normally.

Chen Xin nodded to show his understanding, but after thinking about it for a while, he said to Qin Lan: "Then you can help me contact Uncle Ding, and tell him that I will use the materials for the next two months as collateral and advance some materials with him, and if I want to go back to my hometown to pick up my parents, I need to prepare sufficient materials." ”

"I'm afraid it's going to be a little difficult." When Qin Lan heard Chen Xin's request, she couldn't help frowning: "Although the exchange of materials can be carried out as usual, now that all the manpower of the SWAT team should be devoted to dealing with the recent attack, there is no extra energy to collect materials."

Ah Xin, it should be no problem for you to exchange food and other materials, but the other materials are enough, I can only try to help you tell the captain, I can't guarantee what you can exchange. ”

"Okay, I also understand the current situation of the SWAT team, and I'll make a list for you later, mainly for building materials and steel, what to exchange." Chen Xin knew the current situation of the SWAT team, so he also understood what Qin Lan meant.

But he plans to upgrade the entire shelter before setting off to pick up his parents, plus he has to prepare supplies for going out, materials and supplies are indispensable.

"Okay, you give me the list when you go back, and I'll ask the captain." Qin Lan nodded and agreed to the matter.

————————————————

Because the car has been transformed, Chen Xin began to load various materials into the car in the next time.

Water and food are naturally the first to be loaded into the car.

There is no shortage of food for Chen Xin, and there is still a lot of food in his pantry so far, even if he eats it alone, it is enough to eat for half a year.

After taking two boxes of unopened shelter food from the storage room and putting them in the car, Chen Xin estimated that the journey was more than 600 kilometers, and it should be 1,300 to 1,400 kilometers when you count the round trip.

If there is a problem with the road and there is a detour, it may take 1,500 kilometers.

Chen Xin conservatively calculated that it would take about a month to run 50 kilometers a day.

Two boxes of Vault food were his basic rations for the month's journey, and if there were no supplies on the way, they would be his minimum rations.

In addition to these two boxes of shelter food, Chen Xin also planted lettuce in the planter box in the car and brought a bag of seeds.

These lettuces are used as food rations, and can also be exchanged for food supplies with shelters or supply points encountered on the way, although they may not be met along the way, but they pass through several cities on the way through the four provinces, and it is possible to go to the shelters in these cities if necessary.

Of course, these are just materials to prepare for unexpected situations, and what Chen Xin really prepares to eat on the road is a box of canned luncheon meat and a box of self-heating food.

In addition, he also planned to prepare 100 catties of dehydrated vegetables and 100 catties of rice for himself, and planned to wait for the completion of the material exchange this month, and then prepare two boxes of shelter food, so that even if he received his parents, Chen Xin felt that there was enough food on the way back.

As for the domestic water on the road, Chen Xin is not worried about this at all, after all, there is a water tank with a capacity of five tons, so much water is enough as long as it is not wasted.

After all, when Chen Xin was alone before, he used three tons of water a month, and he also prepared a purification filter in the car, so when it was really not possible, the snow on the roadside was also a water source that could be used.

He connected a water hose for rinsing from the washroom next to the garage, and while filling the water tank, Chen Xin was still thinking about what else he hadn't prepared.

He doesn't need gasoline, there are three isotope temperature difference batteries in this car, one to power the engine, one to power the cabin, and one to use as a backup or if necessary, to overload the engine.

The service life of each isotope temperature difference battery is more than ten years, and the rated output power is 200KW.

The food has also been filled in the trunk, 100 catties of rice, 100 catties of dehydrated vegetables with a box of self-heating food and a box of canned food are the main foods on the road, and four boxes of shelter food are emergency reserves, even if there is any accident, it should be enough to eat.

The water is being added by itself, and the outlet of this tank is connected to a purification filter, so if necessary, you can shovel snow directly from the roadside and throw it into the tank as a water source to replenish it, and there is no fear that the tank may be polluted.

Other ...... that need to be prepared

Just as Chen Xin was calculating what else he needed to prepare, Qin Lan, who had already contacted the SWAT team, came to him and said to him: "I have already told the captain about the exchange of materials, and the captain said that there is no problem with what you want, and you can also agree to advance the next two months' trading materials in advance, but the captain said that there is a prerequisite for all this." ”

"Prerequisites? What conditions? Chen Xin looked at Qin Lan, and said to Uncle Ding that he was willing to exchange materials only if there were prerequisites, which did not surprise him, or that he was unacceptable.

"The city is going to use a small shelter that was previously closed, and wants to use the ground source heat pump technology that you provided to the team as the heating and power generation facility for this small shelter." Qin Lan looked at Chen Xin's calm expression, and then explained to him: "That small shelter is about the same size as the one allocated to Li Yulong by the city government, so the captain asked me to ask you, how many ground source heat pumps are needed to meet the heating and electricity needs of such a shelter, how long will it take for you to deliver, and what materials are needed." ”

After listening to Qin Lan's introduction, Chen Xin raised his eyebrows, feeling a little surprised, but he felt that this was reasonable: "Is the city government planning to adopt a new model?" ”

"It may be due to the coal shortage, so I want to share the risk." Qin Lan didn't know why the city government did this, but there was nothing strange about the city government doing this: "Ah Xin, can you solve this problem?" ”

"It's not difficult to solve the heating needs of a small evacuee, as for the electricity ......" Chen Xin touched his chin, thought for a while and said: "If you don't consider planting greenhouses like Xiaolong, fifty ground source heat pumps should be able to meet the electricity for heating and basic lighting, but this number is only my estimate, and I don't dare to guarantee that it will be enough, as for the delivery, it may take two weeks, and the materials are the same as the last transaction." ”
