Thanks to everyone's efforts, in just one week, the spore fog on the ground in a radius of two square kilometers was completely emptied by a large environmental purifier, centered on the Blue Earth Headquarters.

For the first time, human beings can stand on their own homeland with their feet on the ground. Feet on the earth and look up at the sky.

And after owning a large area of usable land, Lin Chen's two five-week plans can finally be implemented.

When Lin Chen made these two plans, he deliberately referred to the characteristics of his homeland and formulated this extremely distinctive five-week plan.

When he was in the magic world before, he had also strongly implemented this kind of five-five plan, and the effect was unexpectedly good.

The one-to-one promotion by the government, according to five years, May, and five weeks, is not only controllable in time, but also can concentrate all human and material resources to ensure that the plan is completed smoothly and on time.

Originally, the two tasks that Lin Chen gave to Steward Huang were the main difficulty points. Whether it is the ecological planting of greenhouses or the establishment of simple arsenals, a large amount of area is required.

But before everyone lived on top of the building, there was no space for you to use.

But now, with the help of a large environmental purifier, Lin Chen has obtained about two square kilometers of usable area.

This is not a small number, and the average smaller village is so big. It is cost-effective into the mu system that Chinese people are familiar with, which is equivalent to about 3,000 acres of land. If such a large space is used well, it is enough to feed a large number of people.

And the yellow steward is also very powerful, after the space problem was solved, he immediately divided his manpower into two waves, respectively to carry out the ecological planting of greenhouses and the establishment of arsenals.

Among them, the ecological planting of greenhouses, the yellow steward is to directly completely bulldoze a park in the safety area and turn it into a super-large area of greenhouse planting area.

Growing in greenhouses does not mean that you can harvest a lot of grain immediately. Even if they are growing genetic crops that have been improved many times before the end of the world, they have a very short harvest period and a strong ability to survive. However, if you want to have a high yield, you need basic chemical fertilizers in addition to water.

If it is according to the original ecological fertilizer method, there are so many people in the entire western district, and it is impossible to meet the cultivation of such a large area of crops by emptying all the public toilets.

But soon Lao Zhao came up with a way to replace ecological fertilizers. That's the corpse that remains on the ground in large quantities of devouring bacteria.

These remnants of the death of the phagoagoagocytic bacteria have been tested by Lao Zhao to be excellent natural fertilizers, which contain a large number of various elements that are beneficial to the growth of plants.

After all, these are the things that are obtained by devouring bacteria and decomposing spore trees. And the spore tree is a strange plant that is extremely vigorous and grows quickly at the same time.

But this frenzied rate of production has led to a frenzied plundering of the earth's nutrients, and there is no life around the area where they grow. This is not just because they spread toxins, but also because of their powerful predatory ability to devour all nutrients.

When phagophagocytic bacteria break down these spore trees, these nutrients can be returned to nature.

Knowing that this gray powder can also be used as a super fertilizer, Huang Guan immediately set up a fertilizer collection team, which is responsible for collecting the gray powder produced by the decomposition of spore trees and using it as fertilizer for greenhouse planting.

Irrigated with this super fertilizer, the production of these greenhouse plants has become extremely vigorous, not only reducing the production time to a week, but also increasing the yield several times.

All kinds of vegetables, turnips, potatoes and other major human vegetable recipes are included in the greenhouse soilless planting.

Just a month later, the crops that had been planted were harvested, especially potatoes and some greens, and the yield was staggering.

For example, potatoes, which people use as a staple food. In Lin Chen's impression, this thing is a typical low consumption and high production capacity. The general yield per mu can be about 5,000 catties, and if the fertilizer is enough, it can even reach 8,000 catties.

However, through soilless cultivation in greenhouses and irrigation with super fertilizer, the yield per mu has directly doubled, reaching an astonishing 16,000 catties.

What's more, the harvest period has been shortened from one and a half months to two weeks.

And for planting land like this, Lin Chen ordered a hundred acres at once. In other words, in two weeks, the entire western district can harvest 1.6 million catties of potatoes relying on this ecological planting field. Take the average daily consumption of four to eight catties of potatoes per person. That's enough potatoes to feed more than 5,000 people in the entire West End for a whole month and a half.

In other words, the output of potatoes alone can feed the people of the entire West District, and with other vegetables and other crops, the diet of the entire West District has suddenly become rich.

As the saying goes, the people live on food. In the last days, to be able to eat a full stomach, and to eat an unlimited amount of open food, it is simply heaven!

All the people in the Western District were simply grateful to Lin Chen. Even many of the homeless people from the surrounding districts have all come to the West Side, wanting to join the Blue Earth organization.

Without him, the other party is in charge of the food, and it is also the type of full management! You can't find such a good thing with a lantern.

Although the food problem in the entire West District has been solved, what makes Lin Chen a little embarrassed is that there is no meat!

That's right, in this last world, all animals are dead. Plants should be better, as long as there are seeds that can sprout again. But after the animals die, humans now don't have the genetic cloning technology to be able to clone those animals again.

Therefore, Lin Chen could only endure his saliva and eat potatoes every day.

As for the kind of technology that can produce artificial meat, he has never seen it at all, so he can only see if there is a chance to dig up which human relics in the future!

On the other hand, the construction of the arsenal is much more troublesome.

Even if there is land and ready-made factories that can be modified and utilized, Lin Chen does not have complete sets of machinery and equipment to carry out production, and there are not enough skilled workers and engineers to work.

But fortunately, Lin Chen had already prepared.

In his plan, these arsenals are currently mainly trained personnel for manual assembly, and as for large-scale mechanized production, it will have to wait until later.

After the factory was roughly established, Lin Chen sent a large number of people to collect all kinds of machinery and equipment in the purification area, ranging from mobile phones and computers to cars and trucks.

As long as it could be towed, Lin Chen ordered all of them to be transported back.

Then he became a full-time repairman with Bi Yuwei during this time.

Regardless of the size of the equipment, what the people below can't repair, all of them will be handed over to him and Bi Yuwei.

Whether it is Lin Chen's repair skills or Biyuwei's material reorganization, these equipment can be restored to their original state, and Biyuwei's skills can also process these parts to improve their accuracy and strength.

The two of them together are almost equivalent to a small processing plant, and they are still that kind of high-precision!

It's just that Lin Chen's repair burns gold, while Bi Yuwei burns spiritual power.

In terms of durability, it is definitely Lin Chen who is stronger, but the rattling sound of this gold burning makes Lin Chen have to continue to recharge.

For the kryptonite artifact of the Gate of Truth, if you want to borrow its power, of course, you need to kill kryptonite.

So during this time, Lin Chen was in pain and happy.

In the morning, I went to the headquarters to absorb the gold collected from all corners of the district, and in the afternoon, I plunged into the arsenal and became a professional repairman to deal with all kinds of incurable diseases.

In just one week, Lin Chen dropped 10,000 krypton points.

The cost is significant, but the results are significant. Not only did the arsenal create a large number of processing machines, but Bi Yuwei was also promoted to a level and became a second-level ability.

Now the little girl's mental power has doubled compared to before, and the number of things that can be processed every day has also doubled.

With Lin Chen and Bi Yuwei in charge, the arsenal of the Blue Earth Organization was successfully established. And completed his first work, a fire support vehicle capable of reprinting three people.
