Looking at the two upgrade plans given by the system, Chen Xin tried to analyze the upgrade content displayed above.

The first option is not difficult to understand, upgrading the protection level of the shelter, which is obviously used to improve the building structure of the shelter and increase the protection of the shelter.

Among the other upgrades, the improvement of the shelter's ability to release disasters made Chen Xin feel that if he adopted this upgrade plan, it is estimated that disasters such as small earthquakes, fires, and landslides should not cause any damage to the shelter.

As for the last two to improve survival comfort and overall technology +1, this is obviously to improve the various conditions of the shelter, and it is Chen Xin's quality of life that is improved.

In other words, this upgrade plan considers that Chen Xin lives alone in the shelter, and then improves and improves his living conditions as much as possible.

For Chen Xin, this plan is more in his arms, and it is also in line with his current actual situation.

Because Chen Xin is only one person, there is no need to expand the shelter now, and there is no need for it.

It's just that the second upgrade plan increases the number of people that the shelter can accommodate, which can't be said to be useless for Chen Xin, at least in the future, if he finds a girlfriend or wife, the shelter will definitely have to add people, and it is impossible to really live alone for a lifetime, right?

And more people also means being able to do more, for example, with enough people to try to expand the shelter's greenhouse, and simply turn it into a plantation to grow vegetables and grains, and even fruits.

This can not only improve Chen Xin's own living conditions, but also exchange excess output for more materials.

Chen Xin has now seen that if this system is simply upgraded with survival points, it is too expensive.

Therefore, he plans to use the second upgrade method as much as possible in the future, collecting all kinds of materials as much as possible to upgrade, which can save a lot of survival points.

Take the fact that he wants to upgrade the shelter, the consumption of 12,000 survival points, if Chen Xin can come up with a ton of high-quality steel and twenty bags of cement, it will be enough to reduce the consumption of this survival point.

If it is an upgrade that only requires dozens or more than 100 items, this is really nothing, but for a large project like a shelter, the savings of one percent are at least more than a thousand points, which is enough for Chen Xin to upgrade the room!

In addition to the overall upgrade of the shelter, which Chen Xin can't afford at the moment, Chen Xin's form lists the upgrades of each room.

"Modular Container House - Bedroom Components, 3000/4500 for Upgrade"

"Modular Container House - Living Room Components, 3500/4200 for Upgrade"

"Modular Container House - Washroom Components, 800/1200 required for upgrade"

"Containerized modular house - distribution room assembly, 2000/3200 required for upgrade"

These are the four container houses in the current Chen Xin Shelter, and they are also the main activity space of Chen Xin at present.

The most expensive upgrades are the bedrooms and living rooms, while the cheapest are the bathrooms.

The bathroom is cheap in Chen Xin's expectations, after all, it is just a small cubicle of less than one square meter added next to the bedroom, which is installed with a set of integral bathrooms, which is basically the same as the bathroom level of some express hotels in terms of conditions, which is not bad, of course, not good.

For the current Chen Xin, this overall bathroom is enough, so although the upgrade cost is cheap, Chen Xin still did not consider upgrading the bathroom.

As for the living room and bedroom, these two places are the main activity spaces of Chen Xin, although the upgrade cost is very expensive, but they are in the forefront in terms of priority of upgrade.

After all, for Chen Xin, after ensuring the basic living conditions, it is time to improve his living conditions.

He has not forgotten that the premise of the system to improve the daily settlement survival point is that he improves his living conditions, and improving his living conditions to make his life better, this can undoubtedly be regarded as improving his living conditions.

As for the power distribution room, Chen Xin did not plan to upgrade this room alone, because the current power distribution room is more than enough to meet the electricity needs of the shelter, and even if Chen Xin upgrades the entire power system, this power distribution room can be afforded, so the power distribution room is not in the first batch of upgrade projects listed by Chen Xin.

Therefore, in Chen Xin's plan, if there are enough survival points, the living room and bedroom are Chen Yu's priority options for upgrading.

However, the living room can be divided into other rooms compared to the bedroom.

For example, the kitchen and medical room that were in Chen Xin's plan before, there are also the entertainment room and communication room planned by Chen Yu after the electronic products are unblocked, and the study room that he plans to separate from the bedroom.

At present, kitchen utensils, medical supplies, and various electronic products are placed in the living room, although this is not impossible, if there is no system Chen Xin will pass like this, but with the system, and the system also requires Chen Xin to improve his living conditions, then Chen Xin obviously needs to separate these rooms to make his living conditions better.

Although I don't know if separating the room in this way will allow the system to increase the amount of daily survival points, separating the kitchen and the communication room is obviously a matter of improving one's own living conditions, which is also very necessary for Chen Xin.

Although he is now eating self-heating food, it doesn't matter if the kitchen is simple, but with the harvest of vegetables in the greenhouse, he obviously needs to stir-fry or stew vegetables if he wants to eat vegetables, and the requirements for the kitchen will naturally increase, and having a special kitchen can also make him eat better.

And the communication room is even more necessary.

If Chen Xin is underground, lacks network and mobile phone signals, and cannot contact the outside world, short-wave radio has become the only channel for Chen Xin to contact the outside world, and after separation, the communication room that has been upgraded by the system can undoubtedly greatly enhance the ability and effect of Chen Xin's refuge to communicate with the outside world, so that Chen Xin can contact the outside world in a timely manner and at the same time better obtain information from the outside world.

This is extremely important for Chen Xin, who is in the shelter and can't go out yet.

After all, Chen Xin has no social fear, although he has been living alone before, and he is not willing to go to a crowded place, but it was in the era when all social civilization was perfect, and he could communicate with people through the Internet.

However, now is the end of the world, and if you are alone and cannot contact the outside world, it will be easy to hold back the problem.

And even if the external environment is stable and Chen Xin can go out, he can't run out for anything, and the communication basically depends on roaring, right?
