Chapter 47

Now that it's decided to exchange vegetables for materials, it's obvious that the greenhouse is the place where Chen Xin needs to upgrade most.

At present, half of the land in Chen Xin's greenhouse is planted with carrots, which will take about two months to harvest. The other half of the land was planted with lettuce and cabbage before. Now that it has just been harvested, Chen Xin needs to re fertilize the land, and then turn over the soil to re sow new seeds.

At the same time of re fertilizing the land, we also need to carry out ploughing, which is commonly known as plowing or arable land.

In this way, the caked part of the soil will be broken to make the soil loose and more convenient for the growth of crops. At the same time, the fertilizer can also be turned into the depth of the soil, so that the crops can better absorb the nutrients in the fertilizer.

Ploughing is one of the most important parts of the whole farming process, and it is also the most tiring of all farm work. This is why there were cattle and even war horses in ancient times.

Because it's too tired to turn a piece of land by manpower alone, the use of animal power can greatly save manpower, improve the efficiency of cultivated land and save time.

After all, cattle farming and human farming are two completely different concepts.

However, Chen Xin's greenhouse is too small, and he has no cattle to use, so he has to dig the land bit by bit with his own hoe.

Fortunately, Chen Xin's land area is not large, and the temperature of the greenhouse is constant. He doesn't have to catch up with the farming hours. He just needs to plant the seeds after digging.

However, even so, it took Chen Xin more than half a day to complete the cultivation of 50 square meters of land and re sprinkle the seeds.

Looking at the land he had finished plowing, Chen Xin hammered his back. He felt that doing farm work was really a tiring job. At the same time, he also thought about whether he should upgrade his farm tools when he was planting greenhouses, so as to improve the efficiency of farmland.

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

Although there is no other thing to do in the shelter, and it's good to do farm work, this kind of physical labor really makes Chen Xin, who has never done farm work in the first 30 years of his life, feel a bit hard. Moreover, it doesn't matter if the area is small only by manpower. When the planting area increases, the use of mechanical force is the right way to improve efficiency.

Maybe you can find Mo Qingyan to change some small agricultural machinery? Although the precious survival can be used to upgrade farm tools, Chen Xin thinks it should not be so wasted. After all, small agricultural machinery, even in this era of doomsday, is not very difficult to start with.

In addition to small agricultural machinery, Chen Xin also plans to get a few additional fill light lamps, which are necessary tools for planting greenhouses and materials for upgrading them.

As for the other materials for planting greenhouse upgrading, they are only steel and cement, which are basically the building materials that will inevitably be used in the expansion of planting greenhouse.

Of course, if Chen Xin adds all kinds of equipment needed for hydroponic cultivation to the upgrading materials, in addition to expanding the land area of the greenhouse, Chen Xin can also produce a layer of hydroponic cultivation plates, so that the planting area of the greenhouse can be doubled.

This is also the difference between using material upgrade and using survival upgrade. Using survival upgrade, you can only choose one of the upgrade schemes given by the system. I can't choose all of them in one upgrade.

However, there is no such problem when upgrading with materials. As long as all the materials needed for upgrading are met, there is no need to consider the problem of one or two. You can upgrade at one time, and both options are required.

As for the functional differences brought about by the two upgrading methods, Chen Xin understands that this may be the function set by higher civilization in order to add fun to the survival game when it was making this system.

After all, for the higher civilized individuals who can play the survival game, what they want is a better game experience.

If you just live in a certain place, and then play doomsday survival by accumulating survival upgrade items, it obviously makes people feel a little negative, and the game experience is poor, after all, there is no real sense of participation.

Maybe I will spend some time in the early stage to build a hiding place or survival cabin for myself, but with the storage of survival, I can give up going out to collect resources and work by myself to improve the living conditions.

But it's different to collect upgrade materials. After all, the resources I collected are used for upgrading. Seeing that the accommodation I built is getting better and better, it will obviously greatly satisfy the sense of achievement and participation of those players.

Moreover, the upgrade of collected resources can also save survival, which means that the system is changing to encourage upgrading with resources.

After all, resource upgrading needs to save survival. When collecting materials, you can save enough survival, which virtually increases the survival probability of players who upgrade with resources.

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

As for those players who directly use survival upgrade, on the one hand, the function of the Upgraded items is weaker, on the other hand, if only survival is used, their upgrade progress will undoubtedly be much slower than that of the players who use resources to upgrade.However, these may be just games for higher civilization, but for Chen Xin, they are treasures that can save lives and greatly enhance his survival probability at the end of the day.

Thinking of this, Chen Xin also made a list to confirm what he needed.

"One hundred kilograms of steel, five bags of cement, a set of hydroponic planting utensils and a light lamp..." Chen Xin counted the resources he needed one by one. He couldn't help shaking his head: "there are a lot of things to be asked for. If I want to exchange these things, I'm afraid it won't be bleeding."

Because half of the area of Chen Xin's greenhouse is planted with carrots that can only be matured and harvested in three months, and the yield of vegetables planted in the other half is extremely limited. Before upgrading the greenhouse, Chen Xin wanted to exchange the current vegetable yield for what he needed. He felt afraid that he would have to give up all his monthly yield.

But it's not too urgent. He can ask Mo Qingyan to help collect materials through uncle Ding's relationship. First, he can use the vegetables produced this month as a deposit. Next month, when the carrots are harvested, he can settle the balance.

With these materials, Chen Xin can upgrade the greenhouse and increase the planting area of the greenhouse four times.

What's more, Chen Xin uses the system to upgrade, which does not have the construction period needed for normal construction, so it can save more time.
