Chapter 3211: Individual invasion

"Boss, are you really going to do it alone?" Scarface grabbed Lin Rui's wrist and whispered, "This is not a hero, you need at least a few helpers."
"Do you think I have been a hero?" Lin Rui looked at him and said, "Not only I did not, I don't want any of my team members to be a hero. Every action, I think twice. So that Crazy Horse is Say that I fight more and more, but I have less courage. And I never think that a person is afraid to be timid. Because we are afraid of death, we can strive to survive in desperation every time. Believe me, this is I think about the result afterwards."
"But there are many things a person can't handle, you need at least a helper." Scarface whispered.
"If there are many people, it is easy to be exposed." Lin Rui shook his head, "And not everyone is good at this task."
"We can't follow, you can do it alone?" Sausage said anxiously.
"Yes, our only chance is to make a covert raid, and we have to lie beside the Red Baron. When there are more people, there will be more variables." Lin Rui whispered, "Assassinate the Red Baron and leave it to me. But you have to help me. Otherwise, after I kill him, I won't be able to escape." Lin Rui whispered.
"How can I help?" Sausage asked.
"Go to the Russian. He found a previously closed underground passage. It may take some time to open it and dig and expand it. But I'm sure that the road should still be open. Because there are no signs of collapse on the ground and the workers before. When I was laying the square, I saw that the soil here is the kind of clay that works well in engineering, and even if there is a partial collapse, it will not be too serious. It can be cleaned out. I need to retreat from there after assassinating the Red Baron. .
Look at it, this channel looks like this. Due to safety issues, both ends of the passage were built with bricks. You must enter from the other end, open up this passage, and when I request, blow up the wall at the end of the secret society headquarters to accept my retreat. Lin Rui drew an underground passage on the ground as a schematic diagram.
"This tunnel secret society doesn't even know?" Sausage was incredibly authentic.
"Yes, this passage was originally intended to allow people in the two buildings to exchange information without being heard. However, after the completion of the construction, due to a slight collapse in the underground passage, officials of the Orumi Federation were afraid of being held accountable and deliberately concealed it. This passage is built with brick walls on both sides. So the people in the secret agency still don’t know, but in the data room of the Orumi Federal Building, it also saves the original construction documents. Sergey has confirmed it. This passage does exist." Lin Rui nodded.
"That means we can after the assassination of the Red Baron. Everyone's attention is on the secret agency headquarters, but we can use the passage to escape from the Federal Building." Yelena nodded.
"Yes, this is what you are going to do, and I will be responsible for the assassination part." Lin Rui whispered. "But before that, you have to do some hard work. Help me dig out the ventilation duct. Yelena, you come to find the location of the duct."
Yelena took out the sniper's rangefinder. She only needs to use a rangefinder to measure the positions of the vents on both sides of the building, and then calculate the points on the straight lines at the two ends at an angle of 180 degrees to find the position directly above the ventilation duct. This kind of underground ventilation pipes are usually arranged in a straight line without special needs, because considering the actual demand, the pipeline is too long and it is not conducive to air circulation. A sniper of Yelena's level relied not only on shooting skills, but also on accurate calculation capabilities. It is not a problem for her to calculate the positional relationship between this point and the straight line and the angle.
After the calculation was ready, they slowly began to retreat and began digging in locations where the enemy could not normally monitor them. O2's people are mostly experienced veterans, and they are no strangers to digging out shelter facilities. Moreover, construction was already underway in the nearby square, and they quickly found relevant tools to start digging. After more than twenty minutes, they dug a metal ventilation pipe of about two meters.
The sausage quickly boiled the pipe wall with thermite. Lin Rui nodded and waited for the pipe wall to cool down and began to drill in. Yelena gave him an M4A1 carbine, gritted her teeth and nodded, and touched a grenade ring on her neck. Lin Rui nodded, he knew Yelena was reminding him of her promise. This grenade ring was the one he gave Yelena jokingly that it was the proposal ring. Yelena kept it forever, and hung it around her neck with a thread.
"Come back alive!" Yelena whispered in his ear.
Lin Rui nodded and got into the pipe. Then he waved his hand and said, "Fill the soil, and then go find Sergey to meet." After finishing speaking, he slowly crawled towards the other end of the pipe. Lin Rui could only rely on the tactical flashlight to move forward in the square ventilation duct. Although the pipe is not very large, it is at least high enough to allow him to sit inside, so there is no obstacle to crawling. But he still had to be careful, beware of the sound of weapons hitting the pipe wall. This sound will spread far in the pipe.
The team members outside covered the opening of the hole with the burnt iron plate and backfilled the soil. There is no peculiar smell in the ventilation duct, indicating that the fan is operating well and the duct is unblocked. After climbing for a while, Lin Rui encountered a rodent-proof grid, but he carefully pried off the surrounding screws with a saber and continued to climb forward. This position of more than 400 meters is not far from the ground, but it appears extremely long in the underground ventilation duct.
At the end of the ventilation duct, there is another rodent-proof grid, followed by a shutter. Lin Rui lay on the inside of the ventilation duct, carefully observing the situation outside through the gaps in the blinds. But he could only see a little light. Like the lighting in the basement, the light is a little whitish, and no sound can be heard around. The communication signal was also blocked because it was in the basement. Lin Rui touched the equipment beside him. He only had an M4A1 carbine, a pistol and a dagger. All that is left is a pre-charged C4 bomb from the sausage.
He doesn't know the situation outside, how many people are outside, let alone where he is in the basement. Thinking of this, he didn't go out immediately, but continued to climb along the ventilation duct. Look for noise with ears against the pipe. The fan room at the end of the ventilation duct he was looking for. Because the ventilation ducts in the basement are mostly driven by multiple fans. Because of the complex structure in large buildings, there are many partition walls, especially in the basement, which will cause poor ventilation inside the building. Outdoor fresh air must be sent into the building through a fan and the air inside the building must be discharged.
In this type of room, there are usually drawings of ventilation lines.
