However, in order to achieve all this, Chen Xin must obtain a stable channel for obtaining materials to ensure that he can obtain sufficient materials so that he can meet the needs of system upgrades.

And he himself must ensure that his shelter can have enough output to be exchanged for supplies.

Otherwise, even if there is an exchange channel, it would be useless if he can't take out the things to exchange.

Under such a premise, planting a greenhouse becomes the key to everything. Only when the production of planting a greenhouse and subsequent upgrades are guaranteed, can everything Chen Xin want be carried out smoothly.

"In this way, the upgrade of the kitchen and weapon cabinets will be placed backwards." Chen Xin made a table on the computer, counting the materials needed for the upgrade, while also adjusting the upgrade priority of various facilities according to his actual needs.

Currently, on the list that Chen Xin has readjusted, the first priority of upgrading is naturally the planting greenhouse. As the top priority, Chen Xin even made red notes.

The next one is the generator, after all, this is the key to ensuring the normal operation of the shelter.

However, the upgrade of the generator is not particularly urgent. If Chen Xin is willing to increase the use of fuel, extend the daily power generation time, or connect the second spare generator to the power system of the shelter, he still does not need to consider the power system issues in a short period of time.

Therefore, although the upgrade priority of power system is very high, it is not something that needs to be upgraded immediately.

The second is the weapon cabinet. After all, if you want to go out, the lack of self-defense weapons will obviously make Chen Xin feel insecure.

As for the upgrade of the communication system that was very necessary for Chen Xin, it was not the kitchen he had planned to upgrade long ago, but the vehicle, his SUV.

This is actually an inevitable choice that is very easy to understand. SUVs are a good choice for transportation in peaceful times, but in this end of the world, especially when Chen Xin still needs to transport vegetables for material exchange, this kind of vehicle that is not designed to carry goods is obviously not enough.

This time, Chen Xin took out the supplies exchanged with Mo Qingyan, which was only half of his monthly output. If the greenhouse was successfully upgraded as planned, even if the ground was used to grow dry rice and hydroponic planting plates to grow vegetables, he could still harvest 1,200 kilograms of vegetables, and about 800 kilograms of carrots after the ground matures.

The total weight of so many vegetables is nearly one ton. If Chen Xin only uses his own SUV to transport it, he may have to run several trips before he can complete it. Not to mention anything else, just the consumption of gasoline is a problem that Chen Xin has to face up to.

Therefore, considering the subsequent transportation needs, it is inevitable that vehicles will be upgraded or a new truck will be built through material exchange.

There is a pickup truck in Mo Qingyan. I used this car to help drag the freezer to Chen Xin’s shelter. However, it was Mo Qingyan’s car, so it’s okay to borrow it. But it’s impossible to ask her to borrow the car every time she wants to transport vegetables, right?

Although Mo Qingyan might not mind, Chen Xin still thinks this is not good.

As for the use of cars in low-temperature environments where temperatures are getting lower and lower in the future, Chen Xin is not very worried about this.

Although most car manufacturers in the world do not have the idle pain to design cars that can be used in polar climates, cars themselves can still be used normally in an environment of tens of degrees below zero.

This was well proved in the north of Yan Kingdom in the past. You should know that the north of Yan Kingdom, especially in the northeast, often falls below minus 30 to 40 degrees Celsius in winter.

Although the use of cars is a severe test in this kind of weather, most cars can still be used normally.

However, anti-freezing is indeed a question that needs to be considered. After all, cars can bear it, but people may not be able to bear it too. The low temperature of tens of degrees below zero can really freeze people to death.

After recording these things that he thought of on this plan, Chen Xin turned off the computer, touched his hungry stomach, and prepared to get some food for himself.

He got the first harvest of vegetables. Chen Xin’s food is now much richer. At least he doesn’t have to eat only one bag of self-heating food every day, but can eat it with vegetables and canned lunch meat, and occasionally add a meal to himself.

The abundance of food not only increases the total amount of energy Chen Xin consumes every day, but also makes the nutrients he obtains more balanced and rich, avoiding the possibility of malnutrition due to food scarcity.

When I came to the "kitchen" in the living room, because the kitchen was removed from the priority of the upgrade plan, Chen Xin's current "kitchen" was just an induction cooker and a set of picnic pots that Chen Xin used outdoors.

Of course, in addition to this, there is a simple cutting board and a fruit knife that can be used to cut vegetables. These are cookware that Chen Xin used to participate in outdoor sports or to survive in the wild.

There was originally a folding gas furnace, but that thing needed an additional gas tank. In this end of the world, Chen Xin felt that the box of liquefied gas he had stored was better to use at critical moments.

Before the vegetables were harvested, Chen Xin could only eat self-heating food every day, so he only used picnic pots as frying pans or small pots for lunch boxes.

Now that there are vegetables and canned food, Chen Xin can at least add stir-fried cabbage or stir-fried lettuce, or stir-fried lunch meat with vegetables and fried lunch meat when eating.

As for canned pork, because considering that these canned foods will be difficult to eat again after eating them, Chen Xin did not eat them every meal very luxuriously, but planned to open one a week to save as much as possible.

After all, it is very likely that it will be difficult to eat pork in the future. On the contrary, it is canned lunch meat. If you don’t mind eating lunch meat with cockroaches or mice as raw materials, Chen Xin believes that he will still eat it often in the future.

Thinking of this, Chen Xin also tore open the packaging bag of the self-heating food, added a little water to it, and placed it aside. Soon the heating bag in the packaging bag reacted with the water, and heat was released.

At this time, Chen Xin took out half of the lunch meat left in the morning from the canned box, cut it into thin slices on the cutting board, and then put it on a frying pan on the induction cooker. After hot and pouring oil on the pan, he put the sliced ​​lunch meat in it and began to fry.

A scent of meat spread with the sizzling sound, making Chen Xin, who had not smelled the scent of meat for a month, couldn't help but move his index finger.
