The process of human transformation of nature is actually the process of competing with other animals and plants for living space.

In such a process, it is impossible to tell who is right and who is wrong, and survival of the fittest is the law of survival of all things.

In just four days, most of the sparrows in the Yunmengze planting area have been cleared, and the finch plague has been initially controlled.

The Ministry of State-owned Assets Supervision and Administration arranged for the replanting of crops, and in accordance with Xu Huang's suggestion, dozens of explosive generators were installed along the railway site between the forest and the planting area.

The loud roar of the exploding generator creates a sonic boom wall, separating the forest from the planting area.

Moreover, the arms of those explosive generators were also glued with some reflective tape that Wei Minsheng brought from the real world.

Between swinging the arm up and down, the tape reflects a harsh glow in the sunlight.

This kind of activity "bird repellent" is much more effective than those immobile scarecrows to repel birds.

With this sonic boom wall and the line of defense constructed by the movable "bird repellent", the sparrows in the mountain forest had to flee deeper into the dense forest in panic.

In order to completely clear the habitat of these sparrows, the trees in these marginal areas have also been cut down in patches.

The finished timber is sent to be processed into square logs or strips, and the remaining branches and leaves and leftovers are used as fuel for the gasifier, and the combustible gas produced is used for the explosive generator to work.

The dense mountains and forests still have many unknown dangers for ordinary members of the Huaxia Kingdom.

Therefore, even if the wild sparrow eggs in Huaxia City can be sold for a good price now, they don't dare to go too deep.

After all, between money and life, anyone alive will make the right choice, because most of the people who make the wrong choice are already dead, and all that survives is a miracle.

In the days that followed, the SDF went deep into the planting area and continued to remove the remaining sparrows to ensure that the replanting work proceeded smoothly.

In the meantime, due to the decrease in the density of sparrows, the firing range of ordinary air guns is too small, which has severely limited their killing efficiency.

After Xu Huang's consent, the military high-pressure air gun equipped with a bracket and a scope was also taken out for training.

The large-scale shooting training also made the Chinese Self-Defense Forces show off.

The accurate long-range strike capability also allowed those wealthy families in the vicinity of Huaxia City to see the combat effectiveness of the conventional military forces of Huaxia State.

Because in their opinion, compared to the ability to hunt black bears from a long distance in a flying artifact, these can only be regarded as the most ordinary combat power.

After killing more than 200,000 sparrows in a short period of time, the sparrows that roamed the Yunmengze area can no longer pose a threat to the seeds of these crops.

After this period of high-intensity shooting training at moving targets, the members of the Huaxia Self-Defense Force have greatly improved both the speed of loading and firing and the accuracy of shooting.

So, under Xu Huang's deployment, the Huaxia Self-Defense Force began to set out for the dense forest, training the use of various weapons in the dense forest according to the training method of special forces in the real world, so as to improve their ability to adapt to self-defense and cooperate with each other.

With the Self-Defense Forces opening the way, the state-owned assets organized manpower to speed up the removal of shrubs in the surrounding woods, destroying the habitat of sparrows and preventing the recurrence of the sparrow plague.

The sparrows that were driven deep into the dense forest, after losing the largest foraging ground in the Yunmengze planting area, their reproductive ability was also controlled accordingly, so that the ecosystem around Yunmengze was balanced again.

And those sparrows that had their fur, internal organs and claws cleaned were sent to the Tuvalu Special District by Wei Minsheng, and became a delicacy in the Tuvalu Special District, dedicating their last finch value.

After the low, dense shrubs were removed, the Ministry of State-owned Assets and Assets Supervision and Administration installed a large number of wooden nests on the tall trunks, in preparation for the use of domestic swallows, which feed mainly on mosquitoes, to replace the sparrows in the area.

At the same time, Huaxia City has also issued strict decrees to protect some designated beneficial birds.

Compared with the real world, Huaxia City's conservation measures do not blindly protect these beneficial birds, they pay more attention to the overall balance of the ecology.

When a protected organism within the control scope exceeds the normal limit and has an impact on people's production and life, the Ministry of State-owned Assets Supervision and Administration will issue some temporary tasks to carry out controllable hunting and killing actions for these protected organisms until the impact is eliminated.

Although sparrows' staple diet is a variety of grains, they still hunt a large number of pests during the breeding season.

To some extent, they may also play a significant role in the suppression of these pests.

But this is dispensable relative to the impact they have on crop seeds.

Even if a wooden nest can attract some house swallows, it will take time for them to grow and grow, and some artificial intervention will be required to prevent the invasion of harmful birds.

Therefore, during this interval, there must be another means of suppressing insect infestations.

When the planted crops grow to a certain extent, the Ministry of State-owned Assets Supervision and Administration arranges personnel to set up chicken nurseries in different areas of the planting area.

The nursery is mainly composed of prefabricated houses, with all the basic living facilities, almost a miniature farm.

The Ministry of State-owned Assets Supervision and Administration (SASAC) has contracted these conservatories to the full members of Huaxia State at very low rents, and of course, these regular members have sufficient security deposits in their personal accounts to be eligible to contract these conservatories.

Chicken farms have also begun to provide a certain number of free chickens to the people who have contracted the nursery, and at the same time provide some prevention and control services for breeding diseases to these specific people.

The Ministry of State-owned Assets Supervision and Administration requires that the number of chickens that each nursery is responsible for breeding cannot be less than 100, and there is no regulation on their breeding time, and the size is counted.

The Ministry of State-owned Assets Supervision and Administration will issue tasks from time to time to conduct spot checks on the number of chickens in these nurseries.

Chickens in the nursery are kept open, and the amount of manual feeding is strictly controlled.

Because, the purpose of the Ministry of State-owned Assets Supervision and Administration is to use these open-range running pheasants to control the number of pests in the fields in a completely ecological way.

The chicks do not affect the crops that have grown up at all, and after they grow up, the growth of the crops continues to achieve a good ecological environment.

And in the water network in the eastern part of Yunmengze, every night, the night lights installed around the round island will be turned on.

A large number of phototactic mosquitoes and moths could not distinguish the difference between the light reflected in the water and the shore, and pounced on the water one after another, only to die in the belly of the fish, which became the dinner of the fish in the aquaculture farm of Huaxia.
