Since it has been decided to exchange vegetables for supplies, the greenhouse is obviously the place where Chen Xin needs to upgrade the most now.

Currently, half of Chen Xin's land in the planting greenhouse has carrots, and it will take about two months to harvest. The other half of the land has been planted with lettuce and cabbage. Now that it has just been harvested, Chen Xin needs to refertilize the land and then turn over the soil to re-soil new seeds.

While refertilizing the land, it is also necessary to plough, which is commonly known as plowing or cultivated land.

This is to break up the lumps of the soil to loosen the soil and make it easier for crop growth. If fertilizer is applied at the same time, the fertilizer can also be turned deep into the soil layer so that the crop can better absorb nutrients from the fertilizer.

Plowing is one of the most important parts of the entire farming process, and it is also the most tiring of all farming work. This is why there were oxen and even war horses used to cultivate land in ancient times.

Because it is too tiring to turn over a piece of land by manpower alone. Using animal power can greatly save manpower, and at the same time, it can improve the efficiency of arable land and save time.

After all, ox plows land and human plows are two completely different concepts.

However, Chen Xin's greenhouse is too small and he has no plowing ox to use, so he can only use a hoe to turn the ground bit by bit.

Fortunately, Chen Xin was not big in the ground and the temperature in the planting greenhouse was constant, so he didn't have to rush to farming. He just had to plant the seeds after turning them over.

However, even so, Chen Xin spent most of the day to plow the 50 square meters of land and sprinkle the seeds again.

Looking at the land he had finished plowing, Chen Xin hammered his back, feeling a little emotional that he was indeed a tiring job. At the same time, he also thought about whether to upgrade the farm tools in his hand to improve the efficiency of the arable land when upgrading the greenhouse.

With the upgrading of the planting greenhouse, the planting area will definitely increase, and the increase in the planting area will inevitably lead to an increase in workload.

Although there is nothing else to do in the shelter and it is good to do farm work, this kind of physical labor really makes Chen Xin feel a little uncomfortable for him, and it doesn't matter if he farms alone rely on manpower to farm. When the planting area increases, using the power of machinery is the correct way to improve efficiency.

Maybe you can ask Mo Qingyan to exchange for a few small agricultural machinery? Although the precious survival points can be used to upgrade agricultural tools, Chen Xin still thinks that it should not be wasted. After all, even in this era of the end of the world, small agricultural machinery is not something that is difficult to buy.

In addition to small agricultural machinery, Chen Xin also plans to make a few more fill lights. This thing is a necessary utensil in the planting greenhouse and is also a material needed to upgrade the planting greenhouse.

As for the other materials for upgrading the planting greenhouse, they are only steel and cement, which are basically building materials that are bound to be used for expanding the planting greenhouse.

Of course, if Chen Xin adds various equipment required for hydroponic planting to the materials used for upgrading, then when upgrading the planting greenhouse, Chen Xin can not only expand the land area of ​​the planting greenhouse, but also adds an additional layer of hydroponic planting tray to double the planting area of ​​the planting greenhouse.

This is also the difference between using material upgrades and using survival point upgrades. When using survival point upgrades, you can only choose one of the upgrade plans given by the system. There is no way to choose between them in one upgrade. I want them all.

But if you use materials to upgrade, there is no such problem. As long as all the materials required for upgrading can be met, you don’t need to consider the issue of choosing one of two at a time. You can upgrade both options at once.

Regarding the differences in functions brought by the two upgrade methods, Chen Xin understood that this may be a function set by higher civilizations to increase the fun of survival games when they were creating this system.

After all, for higher civilized individuals who can play survival games, what they want to get is a better gaming experience.

If you just stay in a certain place and then play doomsday survival by accumulating survival points and upgrading items, it obviously makes people feel a bit negative, and the game experience is also very poor. After all, there is no actual sense of participation.

Maybe you will spend some time to build a hiding place or a living hut for yourself in the early stage, but with the storage of the living points, you can give up going out to collect resources and work yourself to improve your living conditions.

But it is different to collect upgrade materials yourself. After all, the resources you have worked hard to use for upgrades. Seeing the residence you built by yourself get better and better, this will obviously greatly satisfy those players' sense of accomplishment and participation.

Moreover, collecting resources to upgrade can also save survival points, which is equivalent to the system's change direction and encourages the use of resources to upgrade.

After all, resource upgrades need to save some survival points, and you can save enough survival points when collecting materials, which invisibly increases the survival chances of players who use resources to upgrade.

In particular, resources can be stored in advance, and as long as there are enough resources and survival points, they can be upgraded.

As for those players who directly use survival points to upgrade, on the one hand, the functions of their upgraded items are weaker, and on the other hand, if they only use survival points, their upgrade progress will undoubtedly be much slower than those players who use resources to upgrade.

However, these may be just games for higher civilizations, but for Chen Xin, this is a treasure that can save lives and greatly improve his chances of survival in the end.

Thinking of this, Chen Xin hurriedly made a list and confirmed what he needed.

"100 kilograms of steel, five bags of cement, a set of hydroponic planting tools, and fill lights..." Chen Xin counted the resources he needed one by one, and couldn't help but shake his head: "There are a bit too many things to do. If you want to change to these things, I'm afraid it's going to be bleeding."

Chen Xin's planting greenhouse has half of the area that can mature and harvest carrots after three months of planting, and the other half of the vegetable production is extremely limited. Before upgrading the planting greenhouse, if you want to rely on the current vegetable yield to what you need, Chen Xin feels that he may have to supply all his monthly output.

However, there is no need to be too anxious. He can ask Mo Qingyan to help collect materials through Uncle Ding’s relationship, first use the vegetables produced this month as a deposit, and wait until the carrots are harvested next month before the final payment is settled.

With these supplies, Chen Xin can upgrade the planting greenhouse and increase the planting area of ​​the greenhouse to four times the current one.

Moreover, Chen Xin upgraded the system and did not have the construction period required for normal construction, which could save time even more.
