Long Zhan and Dennis walked about 30 meters together, and at the left end of a corner, they saw an iron escalator that could be climbed up.
The two of them came to the escalator and looked up. They saw that they were the manhole covers they had discovered in the old factory.
The opening holes are all welded shut, making them very easy to identify.
Looking out from the inside, it was clear that there was nothing under the manhole cover, and there were no grenades or other disgusting things as Dennis guessed.
After simple DIY, a twistable wrench was installed under the manhole cover to control the two iron bolts.
The iron bolts are as thick as a baby's arms. One on each side is inserted into the cement wall. If the correct opening method is not found, there is no way to open the manhole cover.

After confirming that the manhole cover was positioned on the ground, Long Zhan made another unexpected discovery.
The tunnel under the manhole cover leads directly to the northwest, which coincides with the inexplicable cement road on the ground that connects the Hongshang Gang's lair.
Before Long Zhan didn't understand why there was a cement road connecting the dilapidated warehouse.
Now he understands!
In order to cover up the expansion of the abandoned sewer and build a hidden underground passage, Fuma turned the excavated area into a cement road.
Or they used road construction as a cover to quietly complete the tunnel project below.
This is why Long Zhan searched for a long time and could not find any traces of damage to the ground caused by tunnel excavation nearby.
Having completely confirmed the existence of the tunnel, the next step is the actual invasion.
Both Long Zhan and Dennis took out silenced pistols and were ready to discover the enemy and fight at any time.
At the same time, in order to detect traps in the tunnel and prevent being blown up by the most common trip-type booby traps, Long Zhan also made a simple "detector" for Dennis who was walking in front.
Peel off the paracord you brought with you before and pull out a small core from the middle.
Then withdraw a bullet from the magazine, tie one end of the rope to the center of gravity of the bullet, and tie the other end to the muzzle of the pistol.
The length of the rope cannot be long or short.
The bullet must be only about one centimeter above the ground while maintaining the shooting posture.
In this way, while walking forward while holding the gun in both hands, if there is a trip booby trap on the ground made of a thin material such as transparent fishing line that is difficult to see clearly, it can be detected without even seeing it with the eyes.
Because the muzzle of the gun is in front of the body, if the bullet and the line pulled by the muzzle touch the line that triggers the booby trap, the bullet will stop in place and the line will deform.
The weight of the bullet is too small to trigger a tripping mine.
In this way, even if Dennis does not see the trip booby trap, he can still stop himself in time to avoid being blown up by changing the bullet head.
After Long Zhan made the simple detector, he told Dennis the principle and function.
"I learned another trick, thank you."
Dennis learned another life-saving trick, which is a perfect gift for a sixth-year old man.
"I still have a lot of little tricks like this. As long as you stay with me long enough, you will learn more useful knowledge."
There is a pun in Long Zhan's words, suggesting that he wants to recruit Dennis as his younger brother.
Dennis smiled and said no more.
The two of them walked carefully along the passage.
It was nearly 200 meters from the old factory to the Hongshang Gang's home base. It was not difficult for Long Zhan and Dennis to walk, but it was quite time-consuming.
After all, you have to be careful of the guards in front of you, and you have to be careful of traps that may appear at any time.
The most troublesome thing is to pay attention to the forks in the road. The sewers connect various areas of the train station. If you turn left or right, you may go wrong if you are not careful.
In this world without any means of identifying direction, people with poor sense of direction will definitely get lost.
Dennis is already considered a person with a good sense of direction. Even though he knew the general direction, he still took the wrong step twice while leading the way.
Fortunately, Fuma is a "good guy" and all the forks leading to this tunnel are blocked by him.
In this way, even if Dennis takes the wrong path, he will encounter a wall made of cement bricks before going very far. He only needs to go back again to find the correct path.
The only drawback may be that it takes time.
This distance was less than 200 meters, but Long Zhan and Dennis walked for more than 10 minutes.
Fortunately, it took a long time and there were no accidents.
Not only did I not encounter any guards, I also did not detect any booby traps. It can be said that the journey was uneventful.
Arriving below the main building of the Xingshang Gang base, the structure of the tunnel changed again.
The tunnel is divided into many parts here.
The largest one in the middle leads directly to the interior of the main building. Not surprisingly, it is where Fuma usually enters and exits. The guards on the first floor will definitely focus on guarding it.
Trying to enter the main building from this road is like finding a needle in a haystack.
There is also a small passage on the left and right, similar to the basement passage we came in before. The height inside is only about 1.5 meters.
Long Zhan walked over to the passage on the left and smelled it, and could smell a pungent odor.
No need to guess that it is a sewage treatment pipe.
It's not impossible to invade the Hong Merchant Gang's lair from here, but when there are other options, no one wants to associate with "shit".
Long Zhan and Dennis had the same idea, that is, first go to the right passage and take a look.
The passage on the right is not round like the passage on the left. It is a narrow corridor with old brick walls on both sides. The height is about 1.6 meters and the width is only a little over one meter.
Dennis could walk normally inside as long as he lowered his head slightly.
Long Zhan is a bit frustrating.
Not only did she have to lower her head and bend her waist, but she even had to retract her shoulders and pinch her chest, squeezing forward in the corridor in an extremely funny posture.
After walking forward for less than 5 meters, there was an upward staircase in front of me.
Dennis took the lead and walked up the stairs and saw something familiar on it——
Lots of cables and wires!
There are a lot of black fiber optic cables with brackets and a very recognizable mark starting with the letter "o".
Through these lines, you can confirm what role this channel plays.
It's definitely a power distribution room.
As a dense seven-story apartment building with three entrances, which can accommodate nearly 200 households at the same time, it is not surprising that there are dedicated power distribution channels.
It is a very good idea to break into this building through the power distribution room.
Except it’s so narrow that it’s frustrating!
"Be careful and step softly. We took the stairs up before and should have reached the first floor. There may be guards outside the wall."
Long Zhan lowered his voice and whispered to Dennis, and his pace changed to a silent walk.
