This French underground sewage treatment center, currently unfinished, is mainly used to treat wastewater from uranium mining. The surface part of the building itself occupies a small area, and the underground part uses a box structure, with aeration tanks and sedimentation tanks available. Planning and construction started a few years ago, but due to the turbulent situation in the area, it has not been completed yet.

There are only six or seven guards employed by a French construction company in the sewage treatment center, and they are currently guarding the unfinished construction site there.

When Lin Rui and others were in the car, they had obtained this, the architectural drawing of the underground sewage treatment center through Cobain.

Judging from the photos sent by Cobain, this is an inconspicuous construction site. There are not many construction site giants—tower cranes. Only a small building is under construction, and the criss-crossing pipe network of conventional sewage treatment plants is completely invisible. And rows of pools, because these can only be seen underground. Except for the exit channels, ventilation and evacuation ports and the comprehensive office building currently under construction, the rest of the structures are all located underground.

"According to the information from Cobain, the entire underground part adopts a box structure, which is divided into two floors. The negative floor is located about 5-8 meters underground. It is the operation and maintenance floor, which is the equipment control center and the manpower maintenance center. .

The bottom of the negative second floor reaches a depth of 13 meters underground. It is a hydraulic structure. Aeration tanks and sedimentation tanks of conventional sewage treatment plants are available here. At present, the masonry of the filling wall of the negative layer of the box body has been completed, the waterproofing of the box body, the root puncture resistance layer and the slope-finding layer on the top of the box body have been completed. The remaining box structure decoration, earthwork backfilling at the top of the box body, the decoration of the complex building and the installation and commissioning of automatic control equipment have not been completed. Yelena looked at the information and drawings on the tactical tablet, "If I were, these terrorists would also choose such a place as the starting point of the attack." "

Lin Rui nodded and said, "After all, this is a French site, and this construction site has not yet been completed, and it was built by a French company. Because of the relationship between France and Niger, no one will investigate here. Think about what we should do. How did you get in?"

"There is a main entrance on the west side of the construction site, and this should be the only entrance in the entire project that allows large vehicles to enter and exit. If the Red Tide team comes with those chemical weapons, they will definitely enter from there. So, relatively speaking, there will definitely be there. They have their main defensive force. If we want to avoid conflicts before we find weapons, we'd better avoid that position." Crazy Horse said.

"How about the ventilation pipes? Underground sewage treatment facilities, it is impossible to have ventilation equipment. From the drawings, we can find at least three main ventilation pipes. From this ventilation pipe can lead to any location of the entire underground facility. According to the drawings, they are most likely to hide in the unfinished part of the second floor above the ground, because there is still open to traffic, I am afraid it will be difficult for such a large vehicle to drive directly in." Lin Rui pointed to the map and asked.

"Theoretically, it is possible, and the fans for the ventilation ducts have not been installed, which is equivalent to leaving outlets everywhere. The biggest difficulty now is, what about the local guards? They are very likely to be the same as those last time. The agency completely bought it. If I want to go in, it's best not to disturb these local guards. My opinion is that it can be deployed when necessary and completely removed." Scarface whispered.

"I agree, this is our last chance. If we can't find those chemical weapons, the situation will become very dangerous." Lin Rui nodded, "In this case, we have no choice. Wait for us. After reaching the target location, the first thing to do is to clear the guards on the ground. In addition, you have to be careful. There may also be red tide troops on the ground."

"Understood, anyway, when we get there, the first thing we need to do is to remove all ground targets. If it is confirmed, the chemical weapons are in the sewage treatment center. When necessary, we can notify the Gurkha team and let them come over. Support." Crazy Horse nodded.

Lin Rui thought for a while and said, "Where is the current position of the Gurkha team? Has the communication been confirmed?"

"I have confirmed that their nearest team is only more than 50 kilometers away from the sewage treatment center. If we determine that the chemical weapons are hidden there, they should be there for reinforcements in 20 minutes or at least half an hour. We currently don’t know how many enemy troops there are. This plan should be more secure.” Crazy Horse replied.

"Very well, I agree with your idea." Lin Rui nodded.

Soon, they arrived at the construction site of the sewage treatment center, because the construction site was still under construction, and it was surrounded by simple wire fences. Lights can be seen vaguely inside. Several large-scale construction lamps illuminate the entire construction site dimly in the dark.

Lin Rui's people got off the car in a quiet place and approached the construction site on foot. Crazy Horse bends over, walks a few steps with Lin Rui, crouched on the side of the road and said in a low voice, "It does look weird. Even if they need to work on this site, there is no need to remove such a large area. Grasses and plants. Look at the withered grass on the ground, it's obviously cut by weeding equipment."

"The key is to look at this trace. You have been curious about something in this sewage treatment center. It has been suspended for nearly several months. And these dead grass and plants have indeed been cleared away in the near future. Not only the grass here, but not far away. The small bushes everywhere have been cleaned up. What's the reason they did it?" Lin Rui whispered, "In fact, there is only one purpose, which is convenient for observing the surroundings. Only places that require strict vigilance will be cleaned up like this. The surrounding weeds can be seen clearly. Look at the heights over there."

Crazy Horse knelt down, took out the binoculars, and looked in the direction Lin Rui pointed. The binoculars swept over several unfinished buildings, and Crazy Horse immediately lowered his body. "There are people up there."

"Not only there, but also on the other side. There are ambushes on top of several unfinished buildings." Lin Rui whispered, "That's why I chose to stop here. If we go further, we will be found. It's possible."

Crazy Horse asked in a low voice, "Do you think they have night vision goggles?"

"It shouldn't be there. Large illuminators are installed in those high places. The light is too bright. If they wear night vision goggles, they will not be able to see clearly. As long as we avoid the main road and crawl close, it shouldn't be a problem. Wait until the fence. Below, we can use the billboard hanging outside the wire fence to hide our figure." Lin Rui said in a low voice, "Let the brothers pay attention, follow me."
