After ordering Lan Bofei to lead the army to "Linshui City" and start exchanging banyans with the Northern Expeditionary Army, the protagonist in the main nest has no administrative assistant who can take charge on his own.

Other high-level executives such as Roll and Rambo Wan are all generals, although Rambo Buddha also has administrative ability and experience, after all, it cannot be compared with Rambo Fei.

The protagonist has to go into battle himself and devote all his energy to the planning and construction of the main nest.

In order to solve the tight food supply of the main nest "Qingqiu City" and reduce the possibility of being constrained by other secondary nests, the protagonist will inevitably need to invest a lot of resources to build enough farms and open up farmland.

Farms need to be built in the middle and upper layers of underground nests, although the underground world is theoretically warm in winter and cool in summer, but if it is too close to the surface, it may be due to the fact that the soil cover is not thick enough, and the ability to keep heat and rain will be affected, and one or two sudden cold waves or heavy rains will lead to a large number of diebacks of mealworms and maggots. If it is too low, it will affect the supply efficiency of the worker ants who collect plant feed on the ground.

At the same time, the farm should not be too close to the ants' living quarters and grain warehouses, otherwise there is a possibility of plague or pollution, after all, there is a large number of mealworms and their droppings in the underground closed environment, its smell is not much better, and it is also an important source of pollution.

There is a serious pollution problem in livestock and poultry farms in the human world:

The first is fecal contamination.

Livestock and poultry breeding will produce a large amount of manure, livestock and poultry manure contains a large amount of nitrogen, phosphorus and organic pollutants, etc., if livestock and poultry manure is piled up at will, it is easy to enter the water system with rainwater. As a result, livestock and poultry manure has become the third largest source of pollution in the human world after industrial pollution, domestic sewage and garbage pollution, and is the main cause of some rural environmental pollution.

Fecal contamination is also the source of the next three types of contamination.

The second is water pollution.

The pollution of livestock and poultry farms to water bodies is mainly organic pollution, microbial pollution, and toxic and harmful substance pollution.

If the aquaculture sewage is directly discharged into the ditch or open water without harmless treatment, it is easy to cause eutrophication and pollution of the water body due to the rich nitrogen and phosphorus content in the sewage. High concentrations of sewage are discharged into the river, causing deterioration in water quality.

Sewage has a great impact on the production and life of surrounding people, and even poses a serious threat to drinking water sources. During the Spring and Autumn period in China and before, people like the Jin Kingdom and the Yin Shang Dynasty relocated their capitals many times, and it is believed that because of the deterioration of the environment and the pollution of water bodies caused by a large amount of garbage containing human and animal excrement, the people had to move away from the old capital.

Again, air pollution.

After the fermentation of livestock and poultry manure, a large number of harmful gases such as ammonia nitrogen, hydrogen sulfide, stunin, methane and so on will be produced, which will not only destroy the ecology, but also directly affect human health, causing respiratory diseases such as cough, tracheitis and bronchitis, which not only threaten the safety of the farm, but also endanger the health of the farm employees and surrounding residents.

And the biological waste gas emitted by livestock and poultry in farms, that is, fart, is even one of the culprits of global warming.

Finally, biological contamination.

Feces contain a large number of pathogenic microorganisms and parasite eggs, if not treated in time, mosquitoes and flies will breed, so that the pathogenic species in the environment will increase, the amount of bacteria will increase, so that pathogenic bacteria and parasites will spread, cause the occurrence of zoonotic diseases, and endanger the health of humans and animals. For example, zoonotic diseases such as avian influenza, swine flu, and hand, foot and mouth disease that occurred in the human world in the 21st century are not unrelated to the harsh environment caused by livestock and poultry manure pollution.

The protagonist has learned this lesson in "Dongyang City" before, although the mealworm farm is not close to the water source of the ants, and it is not easy to produce water pollution, but the other three types of pollution are not a lot.

In terms of manure, if the ants in charge of raising it are not cleaned up in time, it will soon accumulate in a mountain. Although mealworm droppings are small, hard, sandy substances that don't smell much at first, once they start fermenting over time, the smell will be unforgettable.

Fortunately, the manure is also an important fertilizer, and the ants will carry it to the field in time.

Even so, the smell of the long-running farm is not much better, and the protagonist rarely visits there anymore. That is to say, the worker ants work hard and complain, and they will not ask for labor insurance benefits.

But these worker ants also pay a price, and the protagonist has noticed that the worker ants in the farm in "Dongyang City" have a lifespan of nearly half that of other worker ants.

The fate of these worker ants is often to suffer from strange illnesses and die of weakness day by day.

In addition to the poor air environment, the protagonist speculates that these worker ants need to use their jaws to carry their feces, causing the germs in the feces to enter their mouths and eventually become ill.

Fortunately, the germ seems to need oral contact to spread, which avoids the great plague inside the ants.

The protagonist has decreed that farm worker ants are forbidden to feed mouth-to-mouth with other ants, and that dead farm ants must be thrown into the fire and burned. Thanks to a series of measures, there was no major epidemic in Dongyang City.

But the only thing that is difficult to change is the short life of the farm worker ants, fortunately, the worker ants have no sense of rights protection, in the human world, the protagonist's farm has long been destroyed by the union, the police and the court.

Farms are important production facilities because they can provide a lot of meat, while farmland can provide plant food and feed for farms, make full use of farm waste, and attract insect prey.

Compared to farms that need to dig underground nests, building farmland sounds simple, but the actual amount of work is not small at all.

To build farmland, the land needs to be leveled, but the ants basically do not have the ability to "move mountains and reclaim the sea", so they can only choose the originally flat land to build farmland as much as possible.

The work of removing stones and stones is equally arduous, and some of the oversized stones and ants have no choice but to let them go. Small stones, which can be moved away using the power of ants or beetles.

Then you have to clean up the original vegetation on the farmland, which is relatively easy to do, choose dry weather, use a pottery knife or stone knife to clear a circle of firebreaks in advance, and light a fire to remove the vegetation.

The ancestors of human beings used to cultivate in this way, and the plant ash produced by burning is still a good fertilizer.

After the seeds are planted, tending is also essential, and while watering is all about the weather, the ants also have to patrol constantly to catch pests.

Ants are unable to plough deeply, and in order to increase food production, it is necessary to plough the land. The protagonist's approach is to scatter a large number of specially searched earthworm eggs in the farmland, and let the earthworms do the work. Even if the earthworms consume a lot of the manure feed that would otherwise be provided to the plants.

With the full support of Dongyang City, the mealworm farm and farmland of the main nest "Qingqiu City" were put into operation after half a month.
