Doomsday Bunker Upgrade Chapter 47: Cultivated land and upgrade materials

Now that he has decided to exchange vegetables for materials, the growing greenhouse is obviously the place where Chen Xin needs to upgrade the most.

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

While re-fertilizing the land, it also needs to be ploughed, which is commonly referred to as ploughing or arable land.

This is to break up the agglomerated parts of the soil to make the soil loose and facilitate the growth of crops. If fertilizing is carried out at the same time, the fertilizer can also be turned deep into the soil layer, so that the crops can better absorb the nutrients in the fertilizer. .

Ploughing is one of the most important parts of the entire farming process, and it is also the most tiring of all farming activities. This is why there were oxen and even war horses in ancient times.

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

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

　　 However, Chen Xin’s planting greenhouse was too small and he had no cattle to use, so he could only use his **** to plow the ground bit by bit.

　　 Fortunately, the area of ​​land to be turned over by Chen Xin is not large, and the temperature of the planting greenhouse is constant, so he does not have to rush to farm, as long as he finishes turning over and plant the seeds.

　　 But even so, it took Chen Xin more than half a day to till the fifty square meters of land and re-sprinkle the seeds.

　　 Looking at the land he had finished ploughing, Chen Xin hammered his back. He felt a little emotional that working in farming was indeed a tiring job. At the same time, he wondered if he should upgrade what he had in his hands when upgrading the greenhouse. Farm tools to improve the efficiency of arable land.

　　With the upgrading of planting greenhouses, the planting area will definitely increase, and the increase in planting area will inevitably be an increase in workload.

　　 Although there is nothing to do in the refuge, and it’s good to do farm work, this kind of manual labor really makes him feel a little bit choking for Chen Xin, who has not done any farm work in the first 30 years of his life, and It doesn't matter if the area is small if you only rely on manpower to cultivate it. When the planting area increases, the use of mechanical power is the correct way to improve efficiency.

Maybe I can get Mo Qingyan to exchange a few small agricultural machines? Although precious survival points can be used to upgrade agricultural tools, Chen Xin felt that it should not be wasted. After all, even in this era of the end of the world, small agricultural machinery is not difficult to get started.

In addition to small agricultural machinery, Chen Xin also plans to get a few more lights, which are a must-have tool in the greenhouse and a material needed to upgrade the greenhouse.

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

　　 Of course, if Chen Xin adds the various equipment required for hydroponic planting to the upgraded materials, then when upgrading the planting greenhouse, Chen Xin will not only expand the land area of ​​the planting greenhouse, but also increase A layer of hydroponic planting trays can double the planting area of ​​the planting greenhouse.

This is also the difference between using materials to upgrade and using survival points to upgrade. Using survival points to upgrade, you can only choose one of the two upgrade plans given by the system, and there is no way to choose both in one upgrade.

But if you use materials to upgrade, there is no such trouble. As long as you can meet all the materials required for the upgrade, you don't need to consider the problem of choosing one or the other. You can upgrade both options at one time.

Regarding the difference in functions brought about by the two upgrade methods, Chen Xin understands that this may be a function set by higher civilizations to increase the fun of survival games when they created this system.

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

If you just stay in a certain place, and then rely on accumulation of survival points to upgrade items to play doomsday survival, obviously people feel a little negative, and the game experience is also bad, after all, there is no sense of actual participation.

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

But it's different when you collect upgrade materials yourself. After all, the resources you've worked so hard to collect are used for upgrades. Watching the residences you build yourself get better and better will obviously greatly satisfy those players' sense of achievement and satisfaction. A sense of participation.

Moreover, collecting resources to upgrade can also save survival points, which means that the system is changing directions and encouraging the use of resources to upgrade.

After all, resource upgrades need to save some survival points. When collecting materials, you can save enough survival points~IndoMTL.com~ This invisibly increases the survival probability of players who use resources to upgrade.

Especially resources can be stored in advance, as long as there are enough resources and survival points, you can upgrade.

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 slower than that of players who use resources to upgrade a lot of.

　　 But these may be just games for higher civilizations, but for Chen Xin, these are treasures that can save lives and greatly increase the probability of his survival in the doomsday.

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

"One hundred kilograms of steel, five bags of cement, a set of hydroponic planting equipment, a fill light..." Chen Xin counted the resources he needed one by one, and couldn't help shaking his head: "This is what I want. It's a bit too much, and if I want to change these things, I'm afraid I'm not going to bleed a lot."

Chen Xin's growing greenhouse has half the area of ​​carrots that can be matured and harvested after three months of planting, and the other half of the vegetable yield is extremely limited. Before upgrading the greenhouse, he wanted to rely on the current vegetable yield to exchange for his own. For what he needs, Chen Xin feels that he may have to supply all his monthly output.

However, there is no need to hurry. He can ask Mo Qingyan to help collect supplies through Uncle Ding's relationship, and use the vegetables produced this month as a deposit, and wait for the carrots to be harvested next month. Then proceed to the final settlement.

With these materials, Chen Xin can upgrade the planting greenhouse, quadrupling the planting area of ​​the greenhouse.

Moreover, Chen Xin used the system to upgrade, and there is no construction period required for normal construction, which can save more time.
