Maybe it's a bit of obsessive-compulsive disorder by nature, just like in the game, you have to make up a set with equipment instead of using parts, Chen Xin prefers the whole set of things rather than a single piece, so he prefers to be able to upgrade the room as a whole rather than a single item.

Of course, this is also to save trouble and worry, after all, a set of overall things can be used to use it, and there is no need to work hard to match the various components.

For those who know the know, he certainly knows what parts are more appropriate to use, and can bring different things together to get the best performance.

But what about those who don't understand? Obviously, you can't do this, and people who don't understand it may not even know what the parts are for, so how can you integrate a whole set of things?

So sometimes the whole thing is not necessarily the best, but at least it works.

Although Chen Xin has worked hard to study the survival of the apocalypse, and has carefully understood all aspects of the information, he is obviously not the kind of survival expert who understands everything.

Like a greenhouse, a hydroponic tray and a drip irrigation system, is there a conflict between the two? Can drip irrigation be used in hydroponics? How do fill lights be used to ensure that light is obtained between different crops?

Chen Xin obviously can't answer these questions, and the configuration of his planting greenhouse is still told to him by the group friend who does hydroponic planting in the survival group, if he lets him come by himself, he will also plough the field, sow the seeds and water it.

It is impossible for a person to be all-encompassing, if Chen Xin is a survival master, then he can know what is suitable for him, what things should be upgraded and what functions, and how to ensure his maximum survival probability.

But Chen Xin is just an ordinary outdoor survival enthusiast, his professional knowledge is limited, and it is rare for him to be able to judge what functions he needs according to the upgrade plan given by the system.

If it had been someone else, he might have been clamoring for them all.

Of course, Chen Xin also wants everything, but this obviously requires capital, where did he get so many survival points and all the plans?

And this system is also a bit strange, the upgrade scheme is one of the two, and if you use the survival point, you can only choose one of the two.

If you want to have both, you need to provide the materials required for both upgrade plans to be able to have both upgrade solutions at the same time.

Therefore, Chen Xin can only save survival points now, while thinking about how to spend his survival points when he has saved enough.

Now he can't go out, so he can't go outside to collect resources, so he can only rely on survival points to upgrade.

With his current rate of accumulating at 10 o'clock a day, he can have 3,600 points a year, which is enough to upgrade an entire room, but Chen Xin feels that if this is the case, the existence of this system will inevitably seem too chicken.

Therefore, Chen Xin still considered upgrading some key equipment to improve his living conditions, and also let himself get more survival points from the system every day.

It's just that something should be upgraded, but Chen Xin still feels a little worried.

It's not that he can't find something to upgrade, it's not that he can't afford to be in a hurry, it's that he has too many things to choose from, and it's not easy for him to judge what to upgrade that will allow the system to judge that his survival conditions are improved and he can get more survival points.

Fortunately, Chen Xinxin didn't have many survival points to upgrade now, and there was nothing to do in the shelter, so he had a lot of time to think about how to deal with this problem.

Of course, at the moment, Chen Xin still has to take care of the seeds that have been sown on the 100 square meters of land in the planting greenhouse.

There are three kinds of seeds that Chen Xin sowed, namely carrots, cabbage and lettuce.

Among them, the seeds of cabbage have already sprouted out of the soil because of Chen Xin's treatment in advance, while lettuce and carrots will take a few days to grow.

In Chen Xin's original plan, the seeds of upland rice should be sown together, but because he made a mistake in the area, he can only sow the vegetables first, at least to ensure the supply of vegetables.

Among these vegetables, lettuce is the fastest growing and can be harvested in a month with guaranteed temperature and humidity.

The growth cycle of cabbage is similar to that of lettuce, and it can be harvested in about 30 days if the temperature is right.

However, carrots are slower, and even if the temperature is right and irrigation is guaranteed, it will take three months to harvest, which is the longest harvest cycle of the three vegetables.

But compared to lettuce and cabbage, which are not stored well, carrots can obviously be stored longer and can be eaten for a longer time.

This is also the reason why vegetables are planted first, because vegetables can be harvested in a month and produce as soon as possible.

If you plant upland rice, although you can plant two crops a year, the six-month growth cycle is a bit long for Chen Xin now.

If Chen Xinshou does not have a system, then he will choose to plant upland rice first, take advantage of the fact that the food he reserves is not finished, ensure the supply of food, and after the food is guaranteed, plant a little vegetables appropriately, adjust the taste, and then take some output to other shelters outside to exchange things.

But now with the system, everything is different, if you plant vegetables first, you can not only improve the food, improve the living conditions, but also save some of the consumption of reserve food.

When Chen Xin has saved enough survival points and expanded the greenhouse planting area, he will not cause a shortage of food if he sows upland rice at that time, after all, he can take fresh vegetables to other shelters for food.

You must know that for people who eat mushrooms and mice, fresh vegetables are very rare, and Chen Xin is not worried that he can't change food at all.

After checking the moisture of the soil in the greenhouse, and then turning on the fill light, Chen Xin left the planting greenhouse.

One advantage of greenhouses over outdoor cultivation is that they don't have to worry about pests and diseases, they only need to be irrigated and light, and they can be harvested at the right temperature.

Now that the crops have not grown, Chen Xin has nothing more to do, and it is enough to check whether he needs to water or not.

After closing the door of the planting greenhouse, Chen Xin walked towards the storage room, took a package of self-heating food and a bottle of mineral water, and then returned to the living room to prepare for dinner.

The food is limited, and the consumption is not too large, Chen Xin only eats two meals a day now, although he feels a little insufficient, but he can still fill his stomach.

However, when heating self-heating food, Chen Xin suddenly thought that he should get himself a kitchen? This should be regarded as an improvement in living conditions, right?
