The high threshold for entry can only restrict those at the bottom, but not those who have money and power.

Banna's resident structure has quietly changed since the advent of the household policy, but all people are unaware of this and are still living an ordinary life.

Aoki has been taking care of Niu Niu and dropping biological weapons on those factories that don't change.

Suddenly, one day, after Aoki commanded the environmental defenders to bomb, he saw about 30 people with shotguns on the way back. Aoki was shocked, and hurriedly commanded the flock of birds to go around.

As expected, as soon as the flock of birds bypassed, the group began to curse.

"Dog's day, this bird is all fine."

"I waited here for 3 hours, but I waited in vain."

After Aoki listened, he knew what these people were doing. Looking around them, it's not too convenient to retaliate, wait for the next time.

The next day, Aoki deliberately looked around, and it was strange that he didn't find the group of people from yesterday.

When Aoki commanded the eco-friendly bird to come to the sky above the Qiming battery factory, he suddenly found several people hiding in the corner with shotguns. When they saw the bird coming, they quickly ran out.

Aoki hurriedly commanded the eco-friendly bird to fly away quickly.

Seeing that the birds were flying away, several people hurriedly raised their guns and fired.

"Bang!! Bang!! Several loud noises rang out, accompanied by their swearing.

"Damn, what kind of bird is this, it's a sperm! I didn't even hit a single one. ”

At this time, Wang Qili heard the gunshots, and hurriedly didn't even wear a hat to cover his bald head, and ran out with antiquity in his heart.

But when he saw that the birds had flown away, and there was not even a single feather on the ground, he immediately became angry and scolded the hired hunters: "You waste, you have given you so much money, and you have no ...... at all."

But he only dared to scold a few words, after all, those people were not his subordinates. What he didn't know was that the video had been secretly recorded by several employees and uploaded anonymously online.

Soon, several videos titled "The Boss of Qiming Battery Factory Cares About People's Lives and Uses Controlled Firearms Regardless of the Safety of Employees" was uploaded to the Internet and was known by netizens.

Soon, the security bureau came, confiscated the gun, warned and punished. According to the law, it is necessary to be sentenced, but it was quickly settled by Wang Qili, but Wang Qili no longer dared to blatantly take out the gun.

Wang Qili's matter was soon known to other bosses, so they changed their strategy of squatting in the factory and sought other ways.

As the days passed, all the mountains and forests in Niuniu's area had been seeded by the green trees. At this time, spring has arrived, and with the spring rains, many seeds have begun to sprout in the spring. From a distance, the whole mountain forest appears tender yellow, full of spring.

Aoki is full of joy, this is made by his own hands, and it will become even more beautiful in the future. It's a pity that Niuniu's vitality productivity is not high now, and it has not completely spread to the entire mountain forest. So this year, I'm afraid there is no way for this jungle to return to its original appearance.

Just when Aoki was rejoicing, he saw dozens of people all holding shotguns and finding a bush to hide. Aoki took a look and was sure that it was the same group of people last time, and their current location happened to be where the eco-friendly birds passed back and forth.

When Aoki saw it, he was happy: "Hiding in the grass? What is this not delivered to the door yourself? ”

Aoki checked how many evolved and poisonous animals were in the vicinity of the grass. I looked for it, and there were spiders, centipedes, scorpions, and so on, but they were all one or two, which was completely insufficient. Maybe it's because Niu Niu's vitality has just covered that place, so their degree of evolution is not high.

In the end, Aoki could only find animals that had not evolved. Because Aoki's sense of mind can communicate with animals, Aoki can drive animals that have not evolved. But one of the drawbacks of this is that the animals don't necessarily pay attention to Aoki. Evolved animals, except for some special ones, are generally obedient.

It took Aoki an hour and hundreds of attempts to communicate with a dozen scorpions, which was very difficult.

But by this time, those who were hiding in the grass were already waiting a little impatiently.

"This bird has become a sperm, why hasn't it appeared for so long?"

"You can't have found us, right?"

"Wait a minute, make them look good!"

The crowd whispered and scolded.

While they were scolding the birds, they saw a dozen scorpions crawling in the grass in stealth, approaching people and then creeping up on them, finding a place to sting.

The scorpion raised its tail stinger high and plunged it into their flesh to inject the toxin. Some scorpions may have been in a bad mood recently, thinking that this was not enough, and stinging the flesh of the tragic man.

"Ahh More than a dozen people were hit hard by the pain, screaming frantically, and reflexively jumping up to shake the sharp pain out of their bodies.

The others looked at them inexplicably, completely unaware of what was going on, thinking they had epilepsy. When I saw the stinged black holes on their bodies, I suddenly felt a chill in my heart.

"My day! What a wicked door! ”

Then another person was stung by a scorpion and jumped around in pain.

"Day! This could be a scorpion nest, get out of here! ”

More than thirty people left in disarray, and those who were poisoned were quickly sent to the hospital.

After Aoki chased them away, he continued to direct the bird to harass the factories that were emitting a lot of exhaust gases and sewage, and would not stop if they did not stop.

After almost half a month, the bosses who ignored the environmental damage finally gave in, and instead of allowing the factory to directly discharge sewage and exhaust gas, they reactivated the long-unused wastewater/waste gas treatment project.

At this point, the eco-friendly birds will finally be able to retire, but there will definitely be a time when they will be used in the future.

After laying out the mountains and forests to stop humans from continuing to pollute, the next step is to start restoring the water pollution in the river in front of it.

The first issue is the amount of water. The river has a relatively small amount of water, but Aoki checked the upper reaches and found that the land had insufficient water storage capacity due to massive deforestation, and the current situation of low water volume has finally become the current one. This problem can only be solved after Niuniu's vitality coverage is expanded there.

The second issue is water quality. Because there are residential areas in the upstream, there are no factories, and although the water quality is a bit poor, it is all domestic water pollution, which is easier to deal with.

However, in this section of the river, the main part of water pollution is industrial wastewater, which contains a large amount of acids, alkalis, oxidants, as well as heavy metals such as cadmium, mercury, arsenic, benzene, phenol, dichloroethane, ethylene glycol and other organic poisons.

In this kind of water, fish and shrimp must be dead. And it will be more difficult to govern them.

The water upstream is not very serious, so for the time being, the main thing is to purify the industrial wastewater in these waters. According to human practice, there are three methods, namely physical methods, chemical methods and biological methods. Judging from Aoki's current situation, physical and chemical methods are completely impossible, but biological methods are very suitable for Aoki's role.

The best thing Aoki could think of was to create an ecological environment like a wetland.

There are three major ecosystems on Earth: forests, oceans, and wetlands.

The fact that wetlands can be placed alongside forests and oceans is enough to show their important position in the ecological environment.

Wetlands have a very obvious advantage in treating sewage. Its principle is that the sewage is filtered through the wet soil, leaving various impurities such as heavy metal elements and organic matter in the wet soil. Heavy metals are absorbed by plants, while organic matter is decomposed by microorganisms that live in wet soil, and the decomposed substances are absorbed by plants.

If you look at the river in front of you, it is probably due to soil erosion caused by deforestation in the upper reaches of the river a few years ago, so that a lot of silt has now accumulated on the riverbed, especially in the slow flow area of the river bay, which is the natural wet soil.

On the wet soil, there are also a lot of green aquatic plants, including upright water plants, floating leaf plants, submerged plants and floating plants, with a complete range of types. The most special is duckweed, which occupies most of the part of the slow flow area of the river bay.

"The current thing is to catalyze these aquatic plants, which are the most effective tools for absorbing heavy metals."

Thinking about it, Aoki gathered some of the vitality generated by the sub-tree and gathered it on the river bay downstream of the sewage outlet of this row of factories to catalyze those aquatic plants.

Thankfully, Aoki has not yet found a case where Genki can catalyze microorganisms, and if he really catalyzes a bunch of viruses and causes the death of a large area of organisms, Aoki will really regret it for the rest of his life.
