Wang Xuexin didn't know at first that Chen Fujun's security company was incorporated into Project 035 to cooperate with Wang Xuexin in improving tunnel warfare tactics.
This is because Wang Xuexin no longer took care of personnel arrangements and left all this matter to the chief of staff, who worked with Lao Hei to prepare the tunnel.
On the other hand, the guards were tight-lipped. They should have received special confidentiality training or had discipline in this area. When they met Wang Xuexin, they would just say hello and never mention the 035 project or tunnel digging.
It wasn't until later that the security company was needed to mobilize people, and Wang Xuexin was shocked to find out that it was Chen Fujun, Qiangzi and his gang.
At that time, Wang Xuexin couldn't help but admire him. After all, there were hundreds of people in this company, so it was not easy to be able to keep such a strict tone.
Wang Xuexin was a little surprised by Lao Hei.
Lao Hei's skills are indeed passable. The soil in Na Na is too loose and needs wood to support it. No matter how hard you dig it, there will definitely be no problem. Even the tunnel is winding under the ground. He can tell the corresponding position on the ground.
It's almost the same, dig deeper, it's really it.
Lao Hei's skills are eye-opening to everyone, especially when several tunnels need to be connected to each other... This is not as simple as imagined. The height, direction, etc. of the tunnels must be counted underground to correctly understand them.
Get on.
Otherwise, the two tunnels that want to be connected may be staggered without knowing it. This not only wastes manpower and material resources, but may also cause large-scale landslides and cause accidents, especially when the two tunnels are at different heights and overlap...
If the two tunnels intersect on the same level, it won't be a big problem. If one tunnel is above and the other is below, the wall at the top of the tunnel below will be very thin. If you dig, the entire tunnel will collapse or even cause a chain reaction.
This originally required measurement with instruments, or docking with the ground as a reference.
But with Lao Hei here, there is no need for anything. He only needs to walk to the tunnels on both sides. At most, he can step out of the ground and look in the direction of the other tunnel. Then he draws a circle in the tunnel with a hoe and says:
"Dig like this, it's straight!"
Digging forward, it turned out that it was indeed true, and it was accurate as it was said.
I'm afraid this is what people say: "Three hundred and sixty years of practice, and you will be the number one scholar."
Wang Xuexin was not surprised by Lao Hei's abilities. What surprised him was that Lao Hei was not as dull as he seemed on the surface. After entering the tunnel, he came to life as if a switch had been pressed.
Others are not used to entering the tunnel. Sometimes they find it boring and sometimes they find it too damp. As soon as Lao Hei comes in, he immediately jumps up and down without any restraint from the outside world.
Wang Xuexin asked strangely: "Uncle Zhang, you look like a different person! You feel so comfortable here!"
"Comrade Wang Xuexin!" Lao Hei replied: "I, Lao Hei, have stayed in the mine for five full years and have regarded this tunnel and mine as my home. Do you think you still feel uncomfortable returning to your own home?"
Wang Xuexin thought about it and realized that this was indeed true.
He was used to it in the mine but couldn't get used to life outside. No wonder Lao Hei kept hiding in corners outside.
Because of Lao Hei's abilities, Wang Xuexin discussed many of his tunnel digging ideas directly with Lao Hei without going through the chief of staff.
The chief of staff also watched happily.
But from time to time, they would curiously ask: "Comrade Wang Xuexin, why is the entrance to this tunnel dug into a 'concave' shape? It is so inconvenient to get in and out!"
"Chief of Staff!" Wang Xuexin explained: "It is inconvenient for us to get in and out, and it is also inconvenient for the Japanese to get in and out! What's more, if we find a bamboo tube with an empty middle, stick it diagonally toward the exit, and stuff a grenade inside.
You can slide down to the entrance!”
The chief of staff said "Oh" and nodded repeatedly: "That's a good idea! The entrance is narrow and inconvenient to get in and out. If there is a smoking grenade suddenly around the devil, hehe... there will be no place to hide!"
After a while, the chief of staff asked again: "Comrade Wang Xuexin, this tunnel was dug well, why did it suddenly become narrow in the middle and turn a corner?"
Wang Xuexin replied: "Chief of Staff, this narrowed hole is called a hole. If we arrange for one person to hold a long gun here, it will be a barrier for one man and no one can open it!"
The chief of staff said "Oh" again and nodded: "That makes sense!"
"What's more!" Wang Xuexin added: "If the Japanese release smoke or poisonous gas, the hole will be blocked quickly and densely, so we won't be in a hurry and be too late!"
"Yes, yes, that's a good idea!" the chief of staff said and immediately marked it in his notebook.
But sometimes we encounter difficulties that even the old black can't solve.
This difficulty was encountered when the tunnel was to be extended up the mountain to connect with the tunnel fortifications.
There is a large piece of rock ahead, which separates the soil area in the middle and upper part of the mountain. It is basically impossible to dig a tunnel up.
While Lao Hei and the chief of staff were frowning at this, Wang Xuexin came up to take a look and said, "This is not easy. Isn't the truth right here?"
As he spoke, he raised his head toward an irregular rock crevice at his feet that was shoulder-width and a person tall.
"Where?" Lao Hei looked doubtfully in the direction indicated by Wang Xuexin, then frowned and said, "Is this true? The Japs are not blind!"
The chief of staff also said: "If we connect the tunnel to this rock crevice, even the entrance of the tunnel will be in front of the devil!"
Wang Xuexin said angrily: "Can't we fill up this crack in the rock?"
The chief of staff still didn’t understand: “It can’t become a tunnel even if it’s filled in!”
But Lao Hei understood. He slapped his thigh and said, "This makes sense. As long as we use logs to prop up the rock cracks and fill the rock cracks with soil, rocks, etc., the devil will still know the truth."
Is it a crevice?"
When Lao Hei said this, he looked at Xiao Dongbei with admiration.
He also said that he is good at digging tunnels!
This tunnel that has been dug for so many years is almost dead in the tunnel, but it is still not as good as others.
And it's not just this, there is also the tunnel with a simple structure but very practical... At first, he doubted whether this tunnel could fight the Japanese, but now he thinks it's funny.
The chief of staff was stunned for a moment after hearing this. He looked at Lao Hei, then at Wang Xuexin, and secretly wondered if there was such a way to build this tunnel?
But it makes sense to think about it, who stipulates that tunnels can only be dug and not filled?
We've filled in the outside with the surface so we can't see it, so what is it if it's not authentic?
This little Dongbei is really a damn talent!
After hesitating for a moment, the chief of staff quickly took out his pen and notebook, and wrote on it, "Pay attention to the use of rock crevices!"
"What if there is no rock crevice here?" the chief of staff asked casually.
"If there is no crevice and we have to go from here." Wang Xuexin replied: "Let's blow up a crevice and come out!"
The chief of staff almost cried. He felt like a fool.
