Doomsday Bunker Upgrade

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

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. Fertilize, then turn the soil and replant new seeds.

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

This is to break up the agglomerated part of the soil to loosen the soil and make it easier for crops to grow. At the same time, if fertilizing is carried out, the fertilizer can 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 farm work. 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 by 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 is too small, and he has no cattle to use, so he can only use a hoe to dig the ground bit by bit.

Fortunately, the area of ​​land that Chen Xin is going to turn over is not large, and the temperature of the planting greenhouse is constant, so he doesn't have to rush for any farming time.

However, even so, Chen Xin spent most of the day ploughing the 50 square meters of land and planting the seeds again.

Looking at the land he had finished ploughing, Chen Xin hammered his back, feeling quite a bit sighing that doing farm work was indeed a tiring job, and at the same time he wondered if it was time to upgrade the farm tools in his hands when upgrading the greenhouse. Improve the efficiency of farming.

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

Although there is nothing else to do in the shelter, and it is not bad to do farm work, this kind of manual labor is really boring for Chen Xin, who has never done farm work in the first 30 years of his life. When it comes to farming, it doesn't matter if the area is small. When the planting area increases, the use of mechanical power is the correct way to improve efficiency.

Maybe I can find Mo Qingyan to exchange for 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 light supplements, which are a must-have tool in the planting greenhouse and a material needed to upgrade the planting greenhouse.

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

Of course, if Chen Xin adds various equipment needed for hydroponic cultivation to the materials used for the upgrade, then when upgrading the planting greenhouse, Chen Xin can not only expand the land area of ​​the planting greenhouse, but also add a layer of water. Cultivate the planting tray, so that the planting area of ​​the planting greenhouse can be doubled.

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 all of them in one upgrade.

However, if you use materials to upgrade, there is no such trouble. As long as all the materials required for the upgrade can be met, there is no 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 in order 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, it will obviously make people feel a little negative, and the game experience is also poor, after all, there is no sense of actual participation.

Maybe you will spend some time in the early stage to build yourself a hiding place or a survival hut or something, 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 collecting upgrade materials by yourself is different. After all, the resources that you have collected so hard are used for upgrades. Watching the residences you build yourself become better and better will obviously greatly satisfy those players’ sense of accomplishment and 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, which invisibly increases the survival probability of players who use resources to upgrade.

In particular, 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 the items they upgrade are weaker, and on the other hand, if they only use survival points, their upgrade progress will undoubtedly be much slower than players who use resource upgrades.

However, these may be just games for advanced civilizations, but for Chen Xin, this is a treasure that can save lives and greatly increase his probability of 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 a bit too much, 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 growing greenhouse, I wanted to rely on the current vegetable yield to exchange for what I need. , Chen Xin felt that he was afraid that he would have to supply all his monthly output.

However, there is no need to hurry. He can ask Mo Qingyan to help collect materials through the relationship of Uncle Ding first. First, he will use the vegetables produced this month as a deposit, and wait for the carrots to be harvested next month before making the final payment. 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.
