Seeing that gutter oil has penetrated into every corner of Xingzhou and is endangering the health of Xingzhou citizens all the time, everyone feels more and more that the responsibility of this trip is heavy, and they all vow to uproot the underground processing plant of gutter oil in Xingzhou City!

However, smelling the strong fragrance, I can only swallow saliva, looking at the food and not being able to put my mouth down, this is definitely a terrible torment, Zhu Wanjun was the first to stand it, and proposed: "Otherwise, let's go back first, I'll give everyone water to eat, tomorrow we will go to rent a house, we will cook and eat by ourselves, otherwise the case will not be completed, and everyone will be hungry ......."

Ma Nanshan raised his wrist and looked at his watch, waved his hand and said, "Wait, according to my previous investigation, in a little while, the first clue of our case this time should appear!" Only through this clue can we follow the vine and fish out the big fish behind! ……”。

Everyone had to endure hunger and return to the van first, waiting for the clues that Ma Nanshan said to appear, and after a while, Ma Nanshan slapped his thigh hard, and his eyes lit up and said: "It's here!" ……”。

Everyone followed the gaze of Ma Nanshan, and saw an elderly man in rags driving a three-wheeled motorcycle full of swill buckets and dirt, slowly driving along the road, constantly emitting a thick smell of rancid smell and black exhaust along the way, causing pedestrians on the road to cover their noses and quickly escape.

The old man stopped the three-wheeled motorcycle as if nothing happened, removed the empty swill bucket from the car, put it on a small cart, and then went from night stall to night stall to collect swill, and when he came back, the empty swill bucket was already full, and the old man struggled to carry the full swill bucket onto the three-wheeled motorcycle, and then began the next round of transportation.

Looking at the staggering back of the old man, everyone's mood is very complicated, the so-called poor people must have something hateful, this old man is very pitiful to do such heavy physical work at such an age, but he indirectly acts as an accomplice to those gutter oil processing black bosses, and judging from his expression, he is obviously numb to all this, and from this point of view, he is very hateful!

The old man moved four or five times in a row to complete his swill collection for today, restarted the three-wheeled motorcycle, and slowly left, the body shaking, and the swill spilled out of the full swill bucket and sprinkled all the way.

"Tielong, keep up with him, don't lose it, and don't get too close, lest he find out!" , Duan Zetao waved his hand to Hu Tielong with a solemn face, Hu Tielong nodded, started the van, and followed the three-wheeled motorcycle from a distance.

At this time, it has passed 12 o'clock in the morning, there are not many vehicles on the road, but I am not afraid of losing with the three-wheeled motorcycle, "those gutter oil black heart plus workshops are generally located in the urban and rural junction, next to the general pig farm, they filter the swill, slick oil is used to process gutter oil, kitchen waste is used to feed pigs, before 12 o'clock in the morning, these vehicles that collect swill are not afraid to enter the city, because they are afraid of the traffic police to catch, we just follow this three-wheeled motorcycle, we will definitely be able to find a black heart processing workshop for gutter oil!" ......", Ma Nanshan said, staring at the three-wheeled motorcycle in front of him.

Sure enough, the three-wheeled motorcycle quickly drove out of the main urban area and headed towards the urban-rural junction, at this time there were fewer vehicles on the road, and then I saw several almost identical three-wheeled motorcycles driving on several forks in the road leading to the city, which were also filled with swill buckets, and the motorcycles were also driven by several middle-aged and elderly men in ragged clothes.

The elderly man who Duan Zetao and the others followed at the beginning obviously knew the men who came later, and shouted loudly and said hello: "Lao Zhang, business is good today, and the car is almost out of ......."

The man named Lao Zhang replied loudly with excitement and annoyance: "Damn, there are banquets in those restaurants today, and there is a lot of swill, I knew that I would bring a few big buckets, but I still wasted a lot of ......."

Ma Nanshan slapped his thigh hard and said excitedly: "There are a total of six three-wheeled motorcycles, it seems that the scale of this gutter oil black heart processing workshop is not small, at least it is medium-sized, but the gutter oil industry in Xingzhou is so developed, it must have formed an industrial chain, I estimate that there must be a monopoly of underworld forces behind it, as long as we grasp this clue, we should be able to catch the big fish behind!" ……”。

At this time, I had reached the suburbs, and the lights on the road were dimmed, and I could only see the snowy pillars of light from the lights of the tricycles, which turned onto a narrow country road, and it was obvious that they should not be far from their destination.

Duan Zetao and they also turned onto the country road, fortunately, the country road is paved with cement pavement, but it is not difficult to walk, and from a distance, they saw that the pillars of light stopped in front of a large courtyard with dim lights, it is estimated that they have reached their destination, in order not to be discovered, Duan Zetao asked Hu Tielong to stop the car on the side of the lane, turned off the lights, and left a few staff members to guard the car, and he took Hu Tielong and Ma Nanshan to quietly sneak over to find out.

Zhu Wanjun also clamored to go together, Duan Zetao was afraid that she would alarm people by shouting, so he nodded and agreed, and the four of them came to the gate of the big courtyard lightly, and smelled a foul smell from a distance, which was disgusting, but Duan Zetao and they were very excited, because it showed that they had found the right place!

The gate of the yard was open, apparently to facilitate the carrying of the swill buckets, and the swill buckets full of three-wheeled motorcycles were gone, and the stench coming from the yard was even more smoky.

Hu Tielong took the lead, flashed to the gate with agility like a civet, looked inside quickly, beckoned to Duan Zetao and them, signaling that they could go over, Duan Zetao and they hurriedly followed, tiptoed into the courtyard gate, but were stunned by the scene in front of them!

I saw that in the middle of the yard dug a few large pits the size of a septic tank, which were filled with collected swill and residues, the stench was emitted from these large pits, and the edge of the pit was crawling with fat green-headed flies, and in the four corners of the yard were several earthen stoves built with red bricks, on which there were several large iron pots, and there were still residues of solidified white and black grease in the iron pot, which was estimated to be a tool for processing gutter oil, and on the side of the house there was a long row of large iron oil drums, It should be used to load semi-finished products of gutter oil.

"Gross!" , Zhu Wanjun unexpectedly found a floating long butterfly wing female sanitary napkin in the big pit containing swill residue, and could no longer hold back the nausea in her heart, and vomited, fortunately she didn't eat at night, and all she spit out was water.

"Who?!" , I heard a loud shout from the house in the courtyard! The people in the house were alarmed!
