Chen Fujun's guard company was incorporated into the 035 project to cooperate with Wang Xuexin to improve the authentic warfare tactics, but Wang Xuexin didn't know at the beginning.

This is because Wang Xuexin did not take care of the personnel arrangements after that, and he left all the matter to the Chief of Staff, and he and Lao Hei were going to prepare the tunnel together.

On the other hand, the guards were even more nervous. They should have received special confidentiality training or discipline in this regard. When they encounter Wang Xuexin, they just say hello and never mention the 035 project or dig tunnels.

It was not until the guard company was used to transfer people up that Wang Xuexin was shocked to find that it was Chen Fujun and Qiangzi and his men.

At that time, Wang Xuexin couldn't help but admire him. After all, this company was only a hundred people, so it was not easy to keep his mouth so strictly.

Lao Hei surprised Wang Xuexin.

Lao Hei's skills have indeed passed. He needs to support the soil where the soil is too loose, and even if he digs, there will definitely be no problem. Even the tunnel is bent down the ground. The corresponding one is that he can tell everything on the ground. When he digs down, it is true.

Lao Hei's skill has opened everyone's eyes, especially when several tunnels are connected and connected to each other... This is not as simple as imagined. The tunnels are underground, height, direction, etc. to match them.

Otherwise, the two tunnels you want to connect with may be staggered but do not know. This not only wastes manpower and material resources, but also may also cause large-scale landslides and accidents, especially when the heights of the two tunnels are different, up and down,...

It is not a big problem if two tunnels intersect at the same level. If one tunnel is on the upper and lower tunnels, the wall on the top of the tunnel below will be very thin, and as you dig, the entire landslide may even cause a chain reaction.

This originally required instrument measurement, or the ground was used as a reference for docking.

But with Lao Hei, he would not need anything. He just needed to walk to the tunnels on both sides. At most, he would walk out of the ground and look in the direction of the other tunnel. Then he took the mountain hoe and drew a circle in the tunnel and said, "Dig it according to this, straight!"

Digging forward, it was true, and every word was accurate.

This is probably what people say, "Three hundred and sixty professions, every profession will produce top scholars."

Wang Xuexin was not surprised by Lao Hei's ability. What surprised him was that Lao Hei was not as dull as he looked on the surface, and he started to live like a switch after entering the tunnel.

When others enter the tunnel, they are disagreeable with this and that. They feel bored and trendy for a while. When Lao Hei comes in, he immediately jumps around without any restraint from outside.

Wang Xuexin asked strangely: "I said Uncle Zhang, why do you feel like you have changed your personality inside and outside? Here you are... free!"

"Comrade Wang Xuexin!" Lao Hei replied: "I, Lao Hei, stayed in the mine for five years, and regarded this authenticity, mine and other things as home. Do you think you can still feel uncomfortable when you return to your own home?"

Wang Xuexin thought, this was really true.

He was used to it in the mine but was not used to living the life outside. No wonder Lao Hei always hid in the corner outside.

Because of Lao Hei's skills, Wang Xuexin's idea of ​​digging out the authenticity was discussed with Lao Hei without going through the Chief of Staff.

The Chief of Staff was also happy to watch.

But from time to time, I would ask curiously: "Comrade Wang Xuexin, why did this tunnel entrance be dug into a 'concave' shape? How inconvenient it would be to enter and exit like this!"

"Chief of Staff!" Wang Xuexin explained: "It is inconvenient for us to enter and exit, and it is not convenient for the Japanese to enter and exit! What's more, if we find a bamboo tube, we will be empty in the middle and slanted to the outlet from the inside, and the grenade can slide down to the entrance!"

The Chief of Staff said "Oh" and nodded repeatedly: "This is a good idea! The entrance is narrow and it is inconvenient to enter and exit. If there is a smoke-filled grenade next to the Japanese, hehe... there is no place to hide!"

After a while, the Chief of Staff asked again: "Comrade Wang Xuexin, this tunnel is dug well, why did the middle suddenly become narrower and turn a corner?"

Wang Xuexin replied: "Chief of Staff, this narrowing is called Jikou. If we arrange for someone to hold a spear here, it will be a man who can be a guard and ten thousand men!"

The Chief of Staff said "Oh" again, nodding, "This is reasonable!"

"What's more!" Wang Xuexin added: "If the Japanese release smoke or poisonous gas, it will be dense and fast to block the mouth, and we won't be too busy!"

"Yes, yes, this is a good idea!" said the Chief of Staff and immediately marked the notebook.

But sometimes the difficulties encountered are even unsolvable even if Lao Hei is considered to be.

This difficulty was encountered when the tunnel was about to extend to the mountain and connect with the tunnel fortifications.

Going forward is a large scattered rock, which separates the soil area in the upper part of the mountain, so it is basically impossible to dig an authentic tunnel.

Just as Lao Hei and the Chief of Staff were frowning about this, Wang Xuexin came to see it and said, "This is not easy. Isn't the authenticity here?"

As he said that, he raised his head toward an irregular rock crack that was shoulder-width and one person tall.

"Where?" Lao Hei looked in confusion at the direction Wang Xuexin indicated, then frowned and said, "Can this be a real story? The Japanese are not blind!"

The Chief of Staff also said: "If we connect the tunnel to this rock crack, even the tunnel entrance will be placed in front of the ghost!"

Wang Xuexin said angrily: "We can't fill this rock crack?"

The Chief of Staff still didn't understand: "It can't be authentic even if it is filled in!"

Lao Hei understood, and he slapped his thigh and said, "This is reasonable. As long as you use logs to support the rock crack, fill the rock crack with soil, stones, etc., will the Japanese still know that this is a rock crack?"

When Lao Hei said this, he looked at Xiaodongdong with admiration.

He also said that he was good at digging tunnels!

This tunnel that has been dug for so many years is almost dead in it, but it is still not as good as others.

And it's not just this, but also the simple but very practical authentic structure... He wondered whether this authentic can fight the Japanese, but now he thinks it's funny.

The Chief of Staff was stunned when he heard this. He looked at Lao Hei, then at Wang Xuexin, and thought that there was such a method to build this tunnel?

But it’s right to think about it. Who stipulates that the authentic tunnel is only allowed to be dug but not filled in?

If we fill the surface outside on the ground, we can't tell it. If it's not authentic, what's the point?

This little Northeastern is really a fucking talent!

After hesitating, the Chief of Staff quickly pulled out his pen and took out his notebook, saying "Be careful to use the rock cracks!"

"What if there were no rock cracks?" the chief of staff asked casually.

"If you have no rock cracks and have to leave here." Wang Xuexin replied: "Let's just blow up a rock crack!"

The Chief of Staff almost cried. Why did he feel like a fool?
