Late at night, the dark night sky gives all things a protective color. Many people like to complete some activities that cannot be carried out during the day in this protective color. For example, in the middle of the Guijiang River, there are two black shadows constantly moving upstream with the help of the protective color in the night. However, if you can get closer and carefully observe, you will find that among these two black shadows, one is holding a black object floating on the water surface, while the black shadow in front is striving to swim in front. The black shadow in front not only has to go upstream, but also bring the floating black shadow behind him upstream through the rope tied to him. And more importantly, no matter how hard he works, he still carefully corrects his swimming posture and tries not to let himself paddle in the water.

These two black shadows were very familiar with each other and came to a riverside built by the waterway. The width was only one meter, and the walls were covered with disgusting and sticky objects, and the light was not visible. After scattered out of the drain outlet with foul-smelling sewage, the black shadow on the floating object behind gently took off some small packages and long strips from the floating object, and carefully avoided footprints and traces and walked to the drain outlet.

"Brother Duan, it seems that your movements are going to speed up. The water level has been rising significantly in the past two days, and the rainfall in the upstream is increasing significantly. If this continues, the river will flood here soon..." The black shadow in charge of swimming gasped while reminding his partners to speed up.

"Well, I understand, of course I know that we don't have much time left. Don't worry, I know the right amount. You are resting well outside, and you will depend on you when you go back later..." Pasturbating his partner, Duan Guoyu carefully checked the various equipment on his body, and put a black mask on his face and picked up the things on his feet and crawled into a place full of stench and disgusting and sticky things everywhere.

Entering the dark drainage pipe, Duan Guoyu didn't care about the dirt around him at all. He carefully dragged the long objects behind him all the way through. After walking about 100 meters in, the space suddenly became large. Moreover, there were obviously more pipelines here, and there were drainage pipes smaller than before. This should be a sewage gathering place. Not only did the sewage increase a lot compared to just now, but there was also an extra creature - a mouse - than before.

The mice here were not panicked at the sudden appearance of Duan Guoyu and the lights that appeared in front of them, and they still did whatever they should do. Duan Guoyu did not disturb them. They walked straight to an eastward pipeline and checked the strange things wrapped on their bodies again and said to themselves: "I have to climb here again. Fortunately, the bug's case is indeed wear-resistant and easy to use. If Lanzi's skills are better, it will be more comfortable to wear..."

After saying that, Duan Guoyu turned off the flashlight used to drill into a pipe that was not much wider than his body, and carefully crawled forward without making any sound. He moved his body from half-upright to crawling. The disgusting things in the pipe were mercilessly stained Duan Guoyu's whole body, and some even splashed on his mask and face. However, Duan Guoyu seemed to have no feeling of these nauseating and vomiting things, as if they were not contaminated on him, and still crawled forward inch by inch.

Duan Guoyu crawled forward about a hundred meters along the pipe, carefully avoiding several sewer manhole covers that might expose his body and breathed a few breaths of fresh air there, and finally arrived at the pipe leading to his final destination.

The difference between this pipeline and other sewer pipes is that one side of the cement pipe wall was manually chiseled out a passage ranging from about seven to eight meters long and fifty meters wide and about one meter to fifty centimeters high.

When he arrived at the end of a relatively wide hole that had just been dug out, Duan Guoyu picked up a tool that was about half a meter long and had a flat head. He checked the direction he was going to dig and said to himself: "I'm going to dig the hole like a mouse again. I hope I won't touch too many stones this time..."

The space in the small cave was not large, and because he did not dare to dig forward too hard, Duan Guoyu could only dig a small piece of soil, and every minute, Duan Guoyu would have to stop and rest because of lack of oxygen. In less than five minutes, the sultry cave made Duan Guoyu sweat flowing out, making him as wet as if he had just come out of the water.

Although the excavation progress was not very fast, it was still winning. An hour later, a petite body drilled in along the path that Duan Guoyu passed. Such a petite body was naturally the smallest of the four people. Since it was going upstream, the eldest mate could only take one person upstream from three kilometers downstream of the entrance at a time. In fact, in such a small space, the smaller the body, the more beneficial it was; however, Zhen Lan was unable to dig the soil for a long time to open the road, so he helped Duan Guoyu deliver the excavated soil and transport materials to support the tunnel.

………………………………………

Time went forward for more than ten days. After finalizing the goal and action plan, the four boys and Budi began to prepare various objects needed for the action. Several people first determined the route and time for the night and the action location required for the secret action. Finally, they finalized the place where they were launched in an unmanned place three kilometers downstream of the drainage outlet.

Considering that crawling in the pipes is very shattering the joints of the limbs, and fearing that sharp objects in the pipes will scratch the skin, causing the wound to be infected with sewage, they grew up in front of their grandmother. When they were very young, Zhen Lan, who learned to do needlework from her grandmother, cut the skin of the monster's corpse and made two sets of wear-resistant joint protective gears for himself and Duan Guoyu who were responsible for entering the hole to open the tunnel. In order to cut the skin of the monster with toughness and strength harder than cowhide, Xiao Zhen Lan suffered a lot. He used a cutting knife made of the monster's limbs and pointed the skin into the required size bit by bit, and then used a rope to pierce the spikes on the monster's body and connected it with a rope to finally make the required protective gear. This process is already quite difficult alone, not to mention how much harder Zhen Lan suffered to finally complete these two sets of protective gears in actual operation.

In those days before the operation, the first mate dragged the simple floats made behind him to shuttle back and forth between the water inlet point and drainage outlet under the night. Not only did he find a safe and hidden river route, but he could also rely on some reference objects to clearly follow the established route to reach the destination as quickly as possible without light source lighting. In order to complete this task, even the first mate with a good water quality has suffered a lot; several or even dozens of times each night can exhaust his energy, and in order to try to move forward in a hidden way, the route should often pass through some rivers such as the salinies on the river with complex terrain and environment, which are covered with debris under the water surface, and the debris under the water surface often hurts and scratches the first mate's body.

Although the most physically large and largest among the four people, the most powerful machine was the most powerful, but because his figure was too tall and not conducive to activities in a narrow environment, he could not participate in the task of digging and digging the way. He was a man from the north and was not qualified to be the first mate. Seeing that the other three brothers were so tired every night that he could not participate directly in the action, he could only try his best to complete the production and processing of excavation equipment, and be responsible for pedaling the tricycle borrowed from the school to transport people back and forth on a tricycle borrowed from the school every day.

But Budi's work seemed to be the easiest. It invaded the real estate developers' computers through the Internet, found the most detailed pipeline layout information to make a roadmap, and like a behind-the-scenes operator, it planned clearly from assigning various major tasks to how many spikes were used to pull out the monster's corpse. However, it has to be said that there is a commander like Budi who can think about everything so that the boys can clearly know what they are going to do, and at the same time, they can accurately implement the plan step by step according to the steps on the plan.

After the preliminary preparations were basically completed, the formal action was eight days ago. Even though Duan Guoyu and Zhen Lan had already done corresponding preparations and adaptive training in the early stage, the odor that easily penetrated the mask and inhaled into the lungs and the sticky dirt spreading the pipes in the sewer still made the two vomit. However, the two did not retreat at night, and they forced to vomit and climb all the way, overcame the fear brought by the darkness and the disgusting feeling of the dirt. Among the many pipe branches, they accurately found the sewer pipe leading to the target villa building, and dug the first stick they named the money hole.

This new passage is not about having enough food and having nothing to do. After passing through hundreds of meters of sewers, the eleven-meter sewer leading to the target villa building is only responsible for single-family drainage, so the pipe diameter will never be able to accommodate a person through. Although Budi could come out from there, Budi's big furry head was not as big as a shoulder width of one person. For this reason, the Chinese badminton and Zhen Lan had to dig out a new passage next to the pipeline that could accommodate them. At the same time, the relatively spacious passage also facilitated the transport of a large amount of cash inside.

The excavation tools used by Duan Guoyu and Zhen Lan are not ordinary metal products, but excavation tools made of the monster's forefoot under the guidance of Budi. Although they are much lighter in weight than metal products and have less impact, they are better due to the sharpness and intellect of the chisel. Although corrupt officials will not choose to report the case when they are stolen, what if there is an accident? What if the corrupt officials are dismissed in the future, the police will investigate the stolen money theft of this stolen money? In the market, clues can always be found from the sales and cutoff of excavation tools and other special transformations. No details can be careless under the premise of being careful. An inconspicuous negligence may cause a huge disaster for oneself...

Even though various difficulties had been estimated at the beginning, until the actual implementation stage, there were still various new problems and new difficulties in front of everyone. Several boys and Budi carefully analyzed and handled them carefully, withstood the many difficulties, and inch by inch of difficulty, moving towards the goal...
