As an unknown small city in the third and fourth tiers, Tianyang has a population of more than one million. This figure is already very exaggerated, larger than many famous cities in Europe and the United States. Tianyang also has more than a dozen subordinate counties and districts, with a total population of nearly 10 million.

Huge populations create huge amounts of garbage every day, and very few of them can be disposed of harmlessly. Most of them don't do any sorting, just landfill things. Some don't even fill in the landfill, and simply find an invisible corner to stack in the open air.

Zhou Qingfeng took over the task of dealing with garbage for soul crystals and material quotas, and the next day after returning to Tianyang, he accompanied Lin Wan to run the government department. Xiao Jinlang inquired about the news from it, and Professor Zheng was a staff officer, so he had a general understanding of the situation that day.

There are more than a dozen public and private garbage dumps around Tianyang City, mainly considering the wind direction, water area, rivers and many other aspects, and the valleys are selected that are far away from the urban area and do not affect the groundwater.

Lin Wan led the team to drive around an inaccessible valley with an abandoned public garbage dump. It's inaccessible, forbidden to birds and animals, and behind the barbed wire fence covered with plastic bags is a mountain of garbage piled up with hundreds of thousands of tons.

......, this one place alone is enough for Zhou Qingfeng to clean up. Without efficient means, he will not be clean for the rest of his life.

Xiao Jinlang came forward and asked a small clerk from the city's environmental sanitation bureau to lead the way. People refused to approach, and pointed to the garbage mountain from afar and said: "This place has been abandoned for almost 20 years, and the city has no money to deal with it, so it has been piled up like this."

If you want to do garbage recycling, the city will definitely support it. The city can give a certain subsidy for each part of the cleanup. But to accept the government's supervision, it must be harmless. Now the environmental protection department has a lot of power. ”

The junior clerk is in his thirties, and he feels that he is just bringing people to go through the motions, but he doesn't go into much detail, or he himself doesn't know what the 'historical problem' left over the years is.

The barbed wire fence of the dump is rusty, the iron lock of the gate has long been out of key, and you can smell the stale smell of the garbage dump when you stand outside the barbed wire fence - the garbage problem in Tianyang City is far worse than you think.

Su Mei took out a small drone from the car and took to the air to photograph the entire garbage dump. Judging from the footage received by the mobile phone, the drone can't even take pictures of the valley full of garbage, just as far as the eye can see, there is an endless scene of desolation.

Under the scorching sun, the drone scanned around. Lin Wan put her hand on her forehead and briefly surveyed, and said in a low voice: "This place is remote, no one enters or leaves, and it is suitable for hidden servant work." You can build a completely enclosed factory with some simple machinery to improve efficiency.

We can come back at night and do an experiment. Let's see how efficiently the hidden servants dispose of garbage, what are the specific difficulties, and how much it costs. These need to be planned in detail. ”

Zhou Qingfeng nodded, and everyone went back for the time being. At night, he drove alone and took Mr. Zheng back to the abandoned garbage dump again. He put on a dust mask, used hydraulic tongs to break through the barbed wire, and freed a hundred hidden servants in the faint moonlight.

Old Man Zheng released four ghost believers, and he first led his men to float around, inspected the entire garbage dump, and when he came back, he said, "The main pile here is domestic garbage. Mainly plastic, kitchen waste, waste paper.

Since there is no prior treatment, the situation of waste is very complex, difficult to dispose of, and the recyclable value is low. If possible, it is generally incinerate. If you don't have the conditions, you can only pile it here. ”

Compared to the Hidden Servant, the Ghost has a higher level of perception and intelligence, and is more powerful. Old Man Zheng manipulated them to climb the garbage mountain and began to carry out sorting experiments. On the other side, a hundred hidden servants controlled by Sophia also began to work as a contrast group.

In order to strengthen the work ability of these undead creatures, Zhou Qingfeng also took out the 'Emperor's Tears' that stored negative energy to supplement the consumption of the hidden servants at work.

The test lasted overnight and ended before dawn. The results of the test were mixed.

On the bright side, Sophia's controlled hidden servants are hard-working. Although the force is small, as long as it is properly organized, their efficiency is no worse than that of real human work. If there is an adequate supply of negative energy, they can be available all year round.

Ghost believers can work independently, but they are not much more efficient than hermits. But they have one peculiarity - they can command five or six lower-level hermits under Sophia's organization.

This is equivalent to indirectly increasing the number of hidden servants that Zhou Qingfeng can control. With a simple calculation, with enough ghost believers, Sophia can control 10,000 hermit servants to work.

Judging by the results of the work on night tests. Each hermit can process about two kilograms of household waste per hour. They are not tired, they are not hungry, they do not sleep, and they do not receive a salary. The amount of 10,000 hidden servants handled throughout the day is considerable.

Theoretically up to four hundred tons!

Such a mountain of garbage, which has been piled up for decades and has a stock of hundreds of thousands of tons, can be completely emptied in five years. Plastics, waste paper, and metal parts in the garbage can be recycled and incinerated at a loss. Harmful ones such as batteries are picked out and disposed of separately.

As long as food waste loses moisture, it generally decomposes into mud, and if it remains in place, it will be naturally harmless. In addition, there are some discarded rags, furniture and household appliances, which are either burned or dismantled for recycling.

The hardest part of garbage disposal is sorting. As long as the hidden servant takes care of the most troublesome part, it can be dealt with by industrial means in the future, and there is always a way.

Thinking of 10,000 free laborers to work, Zhou Qingfeng stayed in front of the garbage mountain in the early morning for a long time. In order to avoid the sun, Professor Zheng went underground, but he was also excited: "If this thing is done, the merit will be immeasurable!"

I've been thinking about how to deal with garbage with high technology, but I didn't expect to use the stupidest and most difficult way this time. And there is also the possibility of further optimization with the Hidden Servant, because the undead can be constantly strengthened with negative energy. ”

According to the task description, for every 10,000 tons of garbage processed, Zhou Qingfeng can get a green crystal and a green glue. If you save 100,000 tons and then receive the task reward, you can get Qingjing.

10,000 tons seems like a lot, but according to the estimated processing capacity, it can be done in less than a month. Zhou Qingfeng can continue to improve efficiency if the hidden servant is strengthened, where are these hundreds of thousands of tons of garbage? It's a treasure!

According to the new rules, there is a one-tonne cross-transport quota for every 100,000 tonnes of garbage processed. Although it is limited to ordinary materials, no matter how ordinary modern materials are transported to the other world, it will greatly improve the strength of Zhou Qingfeng's team.

A ton of grain can be eaten happily, and there is no need to gnaw on the hard and bitter oat black bread; A ton of clothing can be light and warm, so that the people in the team are glamorous, full of honor and happiness;

If it is a ton of medicine, a ton of steel, and a ton of the simplest machinery and equipment, it is enough to affect the balance of power. Creation in modern civilization has an overwhelming advantage.

Facing the morning sun, Zhou Qingfeng was agitated. He stood in front of a mountain of garbage more than ten meters high and shouted, "I declare that all the garbage in Tianyang City will be contracted by me!" Don't rob anyone. Whoever robs, Lao Tzu will kill whoever he wants! ”
