They didn't stay at Zhao Yan's house for too long and returned the same way they came.

Lao Kang and Guan Honghou had been waiting for them in the factory for a long time.

Today they were responsible for contacting the local authorities. When they learned that they wanted to improve the local ecological environment, they showed great support.

Guan Honghou: "As long as it can improve the local ecology, they said they are willing to cooperate with our work to the best of their ability, and we can contact them anytime if we need anything."

Dai Li nodded to indicate that she understood.

"Teacher Xiaodai, you have seen the situation in Murakami in person, right?" Lao Kang hesitated to speak, meaning that she didn't know if she was still as confident after seeing the situation on the scene.

Dai Li: "The pollution situation is indeed serious. It's just that the workload is large, but the problem is not serious."

Lao Kang's worries eased a little, so he stopped asking questions.

Guan Honghou couldn't wait any longer, rubbing his hands in anticipation and asking, "Teacher Xiao Dai, when will we start improving the local ecological environment?"

Dai Li: "No rush. I'll first test the soil and water samples I brought back today. The machine parameters also need to be readjusted."

Guan Honghou readily agreed: "No problem, I'm not in a hurry. Teacher Xiaodai, take your time. We are waiting for you."

Dai Li: "Boss Guan, you may not be able to rest. I have other things to trouble you and Boss Kang with."

Guan Honghou: "What trouble is it? That's too formal. If you have anything to ask, Teacher Xiaodai, just tell me. I promise to help you with everything."

Lao Kang also said, "This trouble is my negligence. Everything I do is my job, even if I have to go dig a stinking ditch outside."

Dai Li: "It's not as troublesome as you think. I just want to ask you to find a media outlet and expose the local garbage industry chain and ecological pollution in depth."

Guan Honghou: "That's no problem. I have a lot of media resources at my disposal. I know the directors and editors of several stations. It's just a phone call away. Teacher Xiaodai, even if you hadn't mentioned it, I would have contacted the media. We can't just do things quietly. Good things must be publicized."

Dai Li agreed very much: "After filming his industrial chain, you should know how to deal with the rest of the issues."

Guan Honghou patted his chest and said, "As for external publicity, I'm the best at it. Teacher Xiao Dai, don't worry, I'll make sure that all the people pay attention to it."

Dai Li: "Okay, I'll leave the publicity to you."

They split into two groups, Dai Li took Wu Xuelin to inspect the soil and water quality and adjust the appropriate parameters of the machine.

Guan Honghou immediately contacted the media he knew.

He deliberately chose an influential and authoritative platform that specializes in in-depth news reporting.

It takes time for the program team to prepare and schedule a new program. Their schedule is already full and they cannot spare time to shoot in the near future.

But what a coincidence it is that the ecological problems of Sanqing River have become a hot topic recently, and visiting Sanqing River is part of their plan. Even if Guan Honghou had not made this call, they would have arranged for someone to come and investigate in the near future.

The two sides had the same idea, and they were willing to give Guan Honghou some face, so they immediately decided to send a filming team to Sanqing River for an on-site investigation.

The next day, Guan Honghou and Lao Kang were met by people from the TV station.

The TV station is indeed professional. They did their homework before coming and got a preliminary understanding of the local situation.

They do in-depth news reporting all year round. The most important thing is to ensure the authenticity of the news and truly reflect social issues. They are much more objective than personal bloggers exposed on the Internet.

When they arrived at Sanqing River, they found a hidden culvert on the river bank, with black sewage still flowing out of the culvert that had not completely dried up.

The culvert is pointed towards the village in the distance.

The place where the village discharges sewage is quite far away from DL's factory, about ten kilometers away.

There is also a culvert at the factory. When the TV station went to film, the factory's culvert was draining water, but the water quality was far different from the sewage discharged from the village.

The water discharged from the DL plant is slightly turbid, but generally clear and has no unpleasant odor.

Guan Honghou, the person in charge, even went out of his way to explain: "Our factory has a comprehensive sewage treatment system and has always strictly adhered to national emission standards. We have never discharged waste secretly. The discharge you are seeing now is consistent with our long-standing emission standards."

After filming Sanqing River, the program crew finally started to enter the village.

They filmed the entire process in the form of an undercover investigation. The local villagers who were in the garbage business had no idea that they were reporters. They proudly introduced to them how prosperous the garbage business was at the time, and how many people made a fortune from the garbage business, built houses and bought cars.

The villagers also demonstrated to reporters their process of smelting and extracting precious metals, introducing each step in detail.

During the undercover investigation, the reporter interviewed some villagers.

When asked whether they had considered environmental issues, each villager had their own opinion.

"No matter how good the environment is, it can't be eaten. We used to have a good environment here, with lush green mountains and clear waters, but back then we were so poor that we had to eat wild vegetables and tree roots. We couldn't even have meat during the New Year. I never wore new clothes from childhood to adulthood, and even borrowed clothes for my wedding. The fact that we can live in a nice house and eat meat now is all thanks to this garbage. If we quit, where will we go?"

"You say garbage disposal pollutes the environment, but that's because you city dwellers produce so much toxic and hazardous waste. If you didn't produce garbage, how could we have so much trash here? Those who criticize us, ask yourselves: how environmentally friendly are you? You gentlemen stay away from the kitchen and are environmentalists, while we butchers are heinous criminals and are destroying the environment."

"We're already doing pretty well here. You city folks haven't seen the garbage disposal plant. The stench over there is unbearable, and it's uninhabitable for over ten miles."

"My family doesn't discharge sewage directly. It's all treated in tanks. Discharging it secretly is someone else's business and has nothing to do with me."

"Have you ever calculated how much garbage is generated across the country every day, and how many electronic devices are discarded? This waste has to be dealt with by someone, either here or somewhere else. We are sacrificing our own space to process the nation's electronic waste, and this is a contribution to society."

After three days of visits and investigations, the reporters' undercover filming has come to an end.

During this period, they sent a large amount of video materials back to the station, and the post-production team of the station was busy editing them.

The reporters who came to the local area had no plans to leave for the time being. They learned from Guan Honghou that DL Company seemed to be preparing to manage the local natural environment and restore the local blue sky and green water.

Guan Honghou hopes that reporters will stay to witness the environmental changes in the village and record this historic moment.

With such a good subject for filming, the station and reporters naturally had no reason to refuse.

The TV station edited the materials sent back by the reporters as quickly as possible and broadcast them during the prime time at 8 p.m. The latest episode was also updated on the online platform at the same time.

There is a stark difference between serious social news and bloggers' amateur expose videos.

The social news report clearly investigated the details of the Sanqing River, including the origin of its name, where the upstream waters originate, where the downstream waters flow into, the extent of the pollution, the results of water quality tests, and the sources of pollution.

A series of questions can be answered in this program.

The program content does not distort or take sides, and objectively and impartially exposes the specific reasons why Sanqing River has become a "three-polluted river".

After the program was broadcast, it immediately attracted a large number of netizens to watch.

Among them, DL company is indispensable.

[Beng Tan Xiao Yao]: Such a quick reversal? The local river water problem has nothing to do with DL?

[霜balabala_]：Aren't they also draining water into the river? It's impossible that they have nothing to do with it. The current state of the Sanqing River must also have contributed to them.

[My head is itching and I need to grow a brain]: The discharged water is clearer now, but who knows if it was like this before. I'm afraid it's because it was exposed, so they only recently started to treat sewage according to regulations.

[sukisuki]: I think so too. Maybe they want to stay out of the spotlight recently, so they haven’t discharged sewage.

[Fule FL]: Although the direct discharge of domestic sewage from the opposite village is not a good behavior, it is still far less harmful than the harm caused by industrial sewage and is not even on the same scale.

[Dog Repairers]: Anyway, the village and DL Company are equally responsible. They are all responsible for the river water becoming what it is now. No one can deny their involvement.

As the program's investigation deepened, waste recycling, an industry that had been overlooked, came into the attention of people across the Internet.

The village's methods of garbage disposal, sewage discharge problems, and the ecological environment of the entire village were all laid out before them without any concealment.

Netizens were collectively angry after seeing this.

[言_悠悠]: Directly discharging the wastewater from processing electronic waste? Look at what the water and land have become. These people really deserve to die. They should all be arrested and each given a bucket of wastewater they produced.

[Lactic Acid Bacteria Flavor]: Listen to the name of Sanqing River. The title of the program is really well chosen. It is so ironic that Sanqing River has become the "Three Polluted Rivers".

[Nickname taken by someone else]: It seems like they've been dumping garbage everywhere for a long time, and the local authorities haven't done anything about it. Why can't they arrest them for destroying the environment like this? It really makes me so angry!

[Zzz~]: Haven’t you seen the program introduction? This village has been a garbage town for more than 30 years, and the entire village relies on the garbage waving business to make a living. Think about it rationally, the problem is not that simple. We can’t really arrest all the villagers. Some of the people in the program are already very old. Are we going to arrest those in their seventies and eighties and put them in jail as well?

[Is it lucky today?] replied to [Zzz~]: Why can't we catch them all together? Do you think you can just destroy the environment by relying on your seniority? You were the ones who said the air was bad and the environment was bad, and now you're the ones who are being treated with care.

[Baby Ji]: But I think there is some truth in what they said. For example, the electronic waste in society is produced by all of us. You and I are all responsible. No one dares to say that they have never produced electronic waste, unless you are still living a primitive life. In that case, you certainly don’t even know about it. No matter how the garbage is handled, it will inevitably pollute the environment, but it’s just in a place that you and I can’t see.

[Lucky Qiqi]: I strongly agree with what an old lady said. My home is near a garbage disposal plant. Let me first explain that the garbage disposal plant near my home is legal and compliant, but the stench is still terrible, especially in summer, when flies are flying everywhere, making your scalp numb. It doesn't mean that there will be no pollution if we operate according to regulations. Anyway, I think we make a great sacrifice for the garbage produced by the whole city.

[Dog brother, you go first]: This is so funny. Nature has the ability to purify itself. How can it be possible to pollute the environment if we operate according to regulations?

[Cooking Twist in Hot Pot] Reply to [Dog Brother, you go first]: Before you say this, you should first learn about the methods of garbage disposal. Then we will see if you can still say that there is no pollution.

Their topics ranged from the pollution of Sanqing River to garbage discussions, and extended to the macro issues of garbage disposal.

People who don’t understand garbage disposal also checked it online and found that things are far from as simple as they thought.

There are four main methods of garbage disposal today: recycling, sanitary landfill, incineration power generation, and composting.

The villagers near Sanqing River use the first method, which is to recycle and refine precious metals and other rare raw materials. The harm is that it will produce wastewater and waste gas, which are difficult to degrade.

Sanitary landfill is the most widely used method with low treatment costs, but it takes a certain amount of time for natural degradation and may pollute groundwater and soil. Crops cannot be grown around the landfill and the groundwater cannot be drunk.

The pollution caused by incineration power generation is easier to understand. It will produce a large amount of polluting gases and dust particles, accelerate the greenhouse effect, and form smog weather.

Composting does not cause any pollution, but it is only suitable for kitchen waste.

During the period when garbage disposal issues were hotly debated, big data also pushed a large amount of relevant information to the public. The garbage problem in the world is equally serious, and the data is shocking.

[Love Mango]: For society to develop, environmental problems are inevitable. This is the price of industrial development. We cannot give up industrialization and return to an agricultural society. We must look at environmental issues rationally.

[Little Coconut]: I understand they're dealing in garbage to make a living. Garbage disposal isn't an easy job; it's hard, dirty, and exhausting, and the money earned is certainly hard-earned. But no matter how hard it is, at least they shouldn't do it the way they do. Uncontrolled dumping of wastewater pollutes the environment, harming us thousands of miles away. They're the first to suffer the consequences. Toxic and harmful heavy metals are everywhere, and if they live there for a long time, even their own villagers will get sick.

What's even more outrageous is that they're smuggling in imported garbage. Why should some countries, wanting nothing to do with their own land, come and pollute ours? They're actually helping us deal with it. Do they have any integrity at all?

Sanqing River has aroused public outrage. With such a large-scale discussion, it is hard for the people of Sanqing River Village to not know about it.

In fact, most of the Sanqinghe villagers saw this social news as soon as possible.

The older people all have the habit of watching TV. When one person saw it, he immediately informed the next person, and soon almost everyone in the village knew about it.

After all, it was not a glorious thing. The next day, everyone tacitly stopped their own small garbage disposal factories and began to deal with the aftermath.

The incident became so serious that it attracted the attention of people all over the country. The people in Sanqinghe Village were confused about the future and didn't know whether they could continue to do the garbage disposal business.

An investigation team would surely come to inspect soon. At this time, everyone was eager to behave themselves, except for Li Ergou, who ran to Zhao Yan's house to settle accounts with him.

That day he saw Zhao Yan traveling the same way as people from other villages, and he led the two people from other villages back to his home.

Including the reporters who came to investigate and expose the incident, they also went to Zhao Yan's home and consulted Zhao Yan about the situation.

Although Zhao Yan's head was blurred, he still recognized Zhao Yan at a glance.

Zhao Yan revealed the most about the village affairs, and even brought reporters to take pictures of his sewage discharge pipes and idle water tanks.

Now the jobs of all the villagers are about to be destroyed by the people brought by Zhao Yan. How can Li Ergou not be anxious with Zhao Yan?

Li Ergou rode his motorcycle to the gate of Zhao Yan's yard and cursed at Zhao Yan in the yard.

"Zhao Laosan, you are a piece of shit. You brought outsiders here to destroy the jobs of the villagers. Now you go out and make a fortune, and you don't care about the lives of the villagers? You team up with outsiders to bully your own people. You, Zhao Laosan, are a traitor!"

There is not only Zhao Yan at home now, but also his two childhood friends who just came back two days ago and plan to help him deal with the family's environmental problems.

When the two childhood friends saw that it was Li Ergou, they immediately rolled up their sleeves and rushed out.

Zhao Yan stopped them: "It's okay, Li Ergou is just a big talker, he's too timid to take action, I'll deal with him."

Zhao Yan walked out and opened the gate. "How did I bully you? Tell me, is there anything false in the TV reports? Are you polluting the environment? Are you illegally disposing of foreign garbage? You don't allow others to point fingers at your own actions?"

Li Ergou: "Yes, you are a man of high character. You have done the most for us. You brought reporters here to expose us. Now the whole country knows that our entire village is a bad guy. You are so capable. You have made us famous throughout the country. Our whole village has to thank you, right?"

As he spoke, he shouted to the villagers who were watching the fun.

Li Ergou's loud voice quickly attracted the villagers. Everyone had stopped working today, so they all came to watch the fun.

However, they are not as shameless as Li Ergou. At most, they complain about Zhao Yan and the reporters behind his back for meddling in their affairs. They are definitely too embarrassed to directly cause trouble for Zhao Yan. They are morally wrong in polluting the ecological environment.

At this moment, no one spoke, letting Li Ergou perform a solo.

Zhao Yan: "Li Ergou, you don't have to be sarcastic and mock me. If you have any dissatisfaction, just say it directly. But I can tell you with certainty that if you want to continue your recycling business in the long run and want to continue to make a living, you absolutely cannot continue to operate as you did before. You must strictly adhere to the standardized processing procedures."

He said this not only to Li Ergou, but also to all the villagers present.

Li Ergou rolled his eyes while picking his teeth.

Zhao Yan: "Li Ergou, don't think that just because you have more people, the higher-ups won't dare to do anything to you. There's always a guillotine hanging over your heads. They didn't kill you before because it was a mercy. Even mercy has its limits. Don't keep provoking them. You should know when to quit. If you don't pull back your neck, when the guillotine falls, it will be too late."

The other villagers couldn't help but shrink their necks.

Even Li Ergou put away his disdainful expression and thought seriously about Zhao Yan's words.

At this time, some villagers remembered that Zhao Yan had mentioned that he wanted to build a sewage treatment plant, so they asked him to confirm it.

"Zhao San, you said you wanted to build a sewage treatment plant. Do you really want to build it?"

After his reminder, other villagers also remembered this matter.

When Zhao Yan found them before, everyone was reluctant, as if he was going to cut their flesh.

In contrast, now everyone is rushing to express their support.

"Zhao San, please build the sewage treatment plant. All of us in the village support you. Let's start a recycling business together."

"Just tell us how much each family wants. I, Hu Da, won't give you a penny less."

"I've long hoped the village would have a collective sewage treatment plant, but no one has built it. It would be great if you could take charge of it. From now on, all the sewage in the village will have a place to be treated."

If Zhao Yan had heard everyone's support a week ago, he would have been very happy, but the situation is different now.

"Everyone, listen to me, the specific situation has changed a bit, and the village sewage treatment plant may not be built."

Zhao Yan's words caused a huge uproar, making everyone in the group feel uneasy.

"Why did you suddenly decide not to build the factory after everything was fine?"

"Is there anyone who objects? Who is it? Tell me their name and I'll persuade them."

"Who else could it be? It must be Li Ergou. Wasn't he just looking for trouble with Zhao San?"

When Li Ergou heard his name, he immediately became anxious.

"What does it have to do with me? I didn't stop Zhao Laosan from building a sewage treatment plant."

Villager: "If you haven't stopped it yet, then just tell me directly, are you willing to pay?"

Li Ergou stammered and was unwilling to answer.

Under the heavy pressure from the villagers, Li Ergou had no choice but to nod in agreement: "Isn't it just the sewage treatment fee? It's no big deal. I, Li Mintao, can afford it."

Zhao Yan: "It's not about sewage treatment fees. I've been looking into garbage disposal machines recently and found that building sewage treatment plants isn't the most environmentally friendly approach. It also wastes a lot of water. Now there are completely zero-pollution, zero-emission machines for garbage recycling. I'm going to recommend the latest garbage disposal machine to you."

His eyes sparkled with excitement as he spoke.

Ever since Dai Li and the others left Zhao Yan's house, Zhao Yan curiously checked the factory opposite Sanqing River.

You wouldn't know until you check. After checking, he and his two childhood friends were so shocked that they were speechless.

They may not have used DL's technology products, but they have definitely heard of the name.

Take Zhao Yan’s son for example. He used the vision correction device produced by DL Company and threw away his myopia glasses since then.

Zhao Yan's parents have also used the vision correction device, and they no longer need to wear reading glasses when reading mobile phones or newspapers.

Zhao Yan's family has never used other products, not because they don't need them, but because he didn't get them.

The same was true for his two childhood friends, who had long been familiar with DL Company.

For this reason, they came back early and, together with Zhao Yan, personally visited Dai Li's garbage decomposer.

The decomposition process of waste in the garbage decomposer produces raw materials that are finer than those smelted by the villagers themselves. There will not be any loss of precious metals, which can greatly improve economic benefits. The classification of recycled resources is automatic and meticulous.

The entire process produces no polluting gases or wastewater, and is clean and refreshing.

The three people still remember vividly the shock that the garbage decomposer brought them.

If they have garbage decomposers, why do they need to build sewage treatment plants?

Their next goal is to encourage everyone in the village to purchase garbage decomposers, fundamentally changing the way everyone recycles resources.

The villagers at the scene looked confused: "What garbage disposal machine?"

"Zhao San, what nonsense are you talking about? How can refining rare and precious metals produce no waste and sewage?"

At the moment, Zhao Yan didn't have the real thing in his hands, so he couldn't explain it to them in detail. Even if he did, they probably wouldn't believe it.

He reassured the villagers, "The machine is in production. You'll see it soon. Then you'll know if I'm talking nonsense."

Li Ergou: "Don't let it take ten or eight years, because by then our whole village will starve to death."

Zhao Yan: "You'll have to wait even ten or eight years. Tomorrow we're going to start cleaning up our local ecological environment. If you dare to continue processing recycled resources at home, I'll see how stubborn you are."
