Chapter 4958: Under three feet

Lin Rui looked at the other players, "Do you have any other different opinions on this?"
"Nothing. The Russian is really an expert in this area. There is no technical problem." Sausage shook his head.
"Then follow the Russian method. Everyone must remember that this is only a reconnaissance mission. Our purpose is not to get in contact with the target person or rescue the target person.
Our purpose is to detect the surrounding situation and make plans for the next action. Do you understand what I mean? "
"Understand the boss, you don't want to be too aggressive." Sergey nodded.
"Be smart, then start preparing immediately. Bring everything that should be brought. We may have to drill into the sewer several times." Lin Rui smiled slightly.
The brethren under him immediately began to prepare. Sheergai was indeed an expert in sneaking, and he organized a lot of messy equipment.
The purpose of each item was explained in detail to the other mercenaries.
That night, they tried to enter the sewer for the first time. Everyone was wearing diving suits, wearing breathing masks, and carrying equipment into the sewer.
The sewer is full of all kinds of dirty debris, pungent smell, and even mice, running around them.
The straight line distance is only more than 400 meters. There are many side roads, and there are side roads in these side roads. It is intricate and connected.
What they rely on at this time is not just a map, but also a strong memory and sense of direction.
In a small underground space, it is easy to affect a person's mood. Being in such a space can make people feel that loneliness is infinitely magnified, making people very uncomfortable.
Lin Rui thinks this is probably the so-called claustrophobia. Sergey's way of coping with all this is to hum in a low voice.
He hummed a Russian folk song. Climb forward quickly in the sewer. Lin Rui and others followed behind him.
"Well, there is a fork in front. Let's take a look at the drawing. A mark must be made here so that we can find it when we come back." Sergey drew out the dagger he carried with him and carved one on the wall of the sewer. Arrow symbol.
Suddenly Sergey hesitated, "It doesn't seem to be right."
"What's wrong?" Lin Rui asked.
"There is one more fork here than on the drawing." Sergey looked at the map.
"What's going on? Is it the wrong way?" Lin Rui asked.
"Russian, did you lead the wrong way?" Sausage asked.
"Absolutely impossible. This is the first fork in the road. How could I have taken the wrong path. There must be a problem with the drawing." Sergey shook his head.
"This drawing is a few years ago, and it may have been remodeled in recent years. But this is not to blame Ke Ben, he only found such a drawing. And I don't know in advance that there will be other changes in the future." Lin Rui Lowered his voice.
"But it will be even more troublesome. We ruled out the new pipeline and found the right junction." Sergey nodded.
"The new sewer pipe should be visible, which is equivalent to other old pipes that should be able to make some basic judgments." Sausage said.
‘"Of course I can see whether it is new or old. But the problem is that this new pipeline has disrupted our original route.
Now we can only cross the river by feeling the stones. Let's try a little bit. It just takes a little more time. I hope our luck will be better. Sergey sighed.
Their luck was not so good. After traveling some distance, they found that they had gone the wrong way, and they had to turn back and choose another entrance.
After turning back twice, it was the third time that they had found the right route.
Because it's the same as mentioned in their plan, this paragraph. I don't know why it is so low. There is a height difference between and both ends, forming a long distance of stagnant water.
This is why they need oxygen masks and diving suits.
"How can this sewer be designed like this? The middle is hollow and both sides are high. Can it not accumulate water?" Sausage couldn't help but shook his head.
"You don't understand, this is the original sewer, which was later excavated and rebuilt, but in order to control costs as much as possible, some original facilities were used.
Therefore, this sewer is somewhat abnormal, with a lot of water in the middle, which is impossible according to the current design specifications. But it was possible before. Sergey whispered.
Lin Rui also patted, patted the sausage, "It's better to wear your mask. This distance can't be supported by your lung capacity alone."
Everyone put on breathing masks and went underwater. Continue to touch along the pipe.
After walking a long distance, the trend of the pipeline finally went upward. And there is already light coming through somewhere in front.
Lin Rui immediately signaled to the brothers to move forward carefully, and after moving a certain distance forward, they found out. This light source comes from the surface.
The outside sunlight was just right, and a ray of sunlight came in obliquely through the small hole in the top manhole cover.
From this perspective, they are at least three meters above the ground.
The crowd stopped in a relatively open manhole. Lin Rui whispered, "Check the map to see where we are."
"We should be here. This time we went smoothly. This is where we just came out. This is a well, which is where we are.
Continue going forward for a certain distance, then turn right again, and you will reach the observation point we set. Continue from the observation point, and walk about 20 meters is our dive point. Sergey whispered while holding the map.
"Look at how much time we spent?" Lin Rui asked in a low voice.
"It has been more than three hours before and after. But if we didn't take the wrong road before, we can at least control the time within one and a half hours." Sergey replied. "If we become more familiar, maybe we can shorten the time to less than an hour."
"Yes, even this time is a bit tight." Lin Rui lowered his voice. "I remember this maintenance well is not safe, we have to go through it quickly."
"It's not this, you remembered it wrong. The maintenance well is still in front, here is just an ordinary manhole. The maintenance well is still in front." Sergey smiled.
Lin Rui himself felt funny, "There are fork roads everywhere. It is almost impossible to remember the terrain. But how can you remember?"
Sergey smiled, "Thieves have thief roads. If you can't remember the terrain and roads, how can the thief steal things? Where do you run away from?
Therefore, no matter how complicated the road is, you must force yourself to remember it. Over time, a compulsive way of remembering will form. Let's go, we can't pass the maintenance well in front, we have to find a way around. "
