After handing over two boxes of vegetables to Mo Qingyan, she exchanged them for a box of canned luncheon meat, a box of canned pork, a box of rum, a hundred liters of gasoline and a large freezer.

The new SUV with gasoline and exchanged supplies can be placed, but the big freezer is something he can't get back, and the SUV really can't fit such a big thing.

However, Mo Qingyan agreed very righteously to Chen Xin to use his own car to help transport the freezer to his shelter, and he didn't even need his help to pay for the freight, after all, gasoline was still relatively easy to get for them in the city.

After getting all this done, Chen Xin also gave up the idea of continuing to investigate the situation in the urban area, originally he planned to take vegetables to other shelters to exchange supplies, but since he could exchange for what he wanted here in Mo Qingyan, he didn't need to go to other big shelters.

After all, the little vegetables in his hand were enough for Mo Qingyan and them to eat for a month in a small shelter with only a few people, but if they were given to a big shelter, it might not be enough for a meal.

In such a situation, if you go to the Great Shelter to exchange materials, people may not pay attention to it, and the materials you get may not be as much as what you got from Mo Qingyan, not to mention that they may be remembered by others.

Although the shelter in the urban area is still maintaining order under the control of the city government, in the current post-apocalyptic situation, the official will requisition your planting greenhouse, and the whole city will supply materials in a game of chess, let you move to the big shelter, and hand over the greenhouse to professionals to take care of something, does Chen Xin have room for resistance alone?

Although this possibility is not high before the current social order collapses, since the risk of this possibility cannot be ruled out, and there is no need to go to the Great Shelter to exchange materials, Chen Xin can naturally give himself less trouble and less trouble.

As for communicating with the Great Vault, this is an inevitable thing, but before finding a safe way to trade, Chen Xin feels that it is better to avoid communicating with the Great Vault for the time being.

And now the situation in the urban area ...... In fact, it did not show optimism.

Chen Xin drove back in the car, thinking about the information he had heard from Mo Qingyan before, and analyzing the current situation.

"The railway station is still running, and every once in a while there will be trains carrying coal and a small amount of supplies, so that the city government can keep the thermal power plant running, then the power supply in the urban area should be fine, even if the temperature continues to drop, rail transportation should still be guaranteed." Chen Xin's fingers tapped on the steering wheel, and while talking to himself, he was more optimistic about the situation at the train station, one of the three major shelters.

The railway station refers to the city's old passenger railway station, with the city's first underground shopping plaza underneath, but later converted into an underground hotel after the depression.

It's a relatively large area, and there are several large shopping malls around it, and the city government has deliberately connected the surrounding area and transformed it into a sizable shelter.

Coupled with the fact that they are backed by the railway station, their importance in the current situation is self-evident, and the city government will definitely ensure that the train station can operate normally, so the situation of the shelter should be good.

However, the old railway station is indeed old, and the underground space has been rebuilt several times, although the underground space must have been renovated when the official shelter was built before, but the aging of the facilities is an indisputable fact.

Therefore, the conditions of the railway station shelter may be good, but the living environment should be the worst of the three major shelters.

As for the other two shelters, the shopping mall and the pedestrian street, both of them have their own advantages and disadvantages.

The shopping center shelter is the big shelter near Mo Qingyan's house, which is mainly a large shopping center built in recent years, the underground was originally a parking lot and a large shopping supermarket, and the shopping supermarket itself also has a logistics center, which has a lot of advantages in terms of material storage.

Before the disaster, the city government had transferred a large amount of grain from the city's national granary to various shelters, and the shopping center had sufficient storage conditions to distribute a considerable amount of grain, and the grain distributed by several surrounding communities was basically stored here.

However, the problem with the shopping center here is that the place is not big, after all, it is a newly renovated shopping center in recent years, and it is surrounded by residential areas, so the place is really not big.

Even if the underground garage is connected to several surrounding communities, the place is only that large, and the capacity to accommodate the population is limited.

On the contrary, on the other side of the pedestrian street, it was a civil air defense project built during the reign of the previous mayor, and two streets were hollowed out underground, an underground pedestrian street was built, and the original old pedestrian street was transformed into an underground square.

In addition, it is the most prosperous commercial area in the city, and there are many large shopping malls, which are connected to each other underground, so it can be said that it is equivalent to a dungeon.

Moreover, it was built in accordance with the standards of civil air defense engineering, and all facilities are relatively perfect, and the accommodating capacity is of course good, which is the most populous of the three major shelters.

It's just that this also brings a problem, that is, there are more people to eat, and the area around the pedestrian street is full of shopping malls, there are no large-scale supermarkets and logistics centers like the shopping center, the material storage capacity is not good, and the reserve of food will not be too much.

On the whole, the three major shelters have their own advantages and disadvantages, and the railway station relies on railway transportation, which is an important channel for the city to obtain supplies from the outside world, and the survival of this shelter will basically not be a problem.

The shopping mall is actually not far from the city hall, and a large amount of grain is stored here, even if it did not open up the connection with the city government during the previous renovation, the city government will definitely find a way to dig a passage between the two.

On the contrary, although the living conditions on the pedestrian street may be the best, because there are too many people and there are no other advantages, it is very likely to face the dilemma of lack of food and clothing in the future.

As for the other smaller shelters, they also have their own advantages and disadvantages, and it will be difficult to clarify for a while.

Chen Xin simply didn't think about it anymore, Mo Qingyan's refuge was with Ding Ning, backed by the SWAT team and the city police department, what materials he wanted to exchange for through them was undoubtedly much safer, and it was also better to exchange for good things.

Thinking of this, Chen Xin felt that his next development direction could completely increase the output of the planting greenhouse, exchange vegetables for various materials he needed, and use materials to upgrade the shelter, save the expenditure of survival points as much as possible, and at the same time upgrade more projects.

With this thought in mind, Chen Xin also had a new plan for the future development plan of his refuge.
