Xu Rui had long expected that the tunnel entrance would be discovered by the Japanese sooner or later. [The fastest and most complete update of Maopu is free]
After all, the tunnel network in Dameishan Basin is so large, and there are hundreds of tunnel entrances. It is impossible for you to disguise every tunnel entrance without flaws, and it is impossible for you to not be discovered by the Japanese in the end, but Xu Ruizhen
Unexpectedly, the tunnel entrance disguised as a tomb in Xiaoli Village would be discovered so quickly.
You know, this tunnel entrance was designed by Xu Rui himself.
So after receiving the report from the 1st Battalion, Xu Rui rushed over immediately.
When Heiji Kawaguchi caused water from the Mei River to pour into the tunnel, Xu Rui had already arrived at the underground headquarters of Xiaoli Village. At this time, the straight-line distance between him and Heiji Kawaguchi, an old devil, was only less than two hundred meters.
One is underground and the other is on the surface. Neither of them knows the other's existence.
Although the 1st Battalion sent an observation post in the village, in the darkness, it was impossible to see the rank on the old Japanese soldier clearly.
If Xu Rui knew that an old devil like Kawaguchi Heiji was in Xiaoli Village right now, he might really take the risk and fight.
Xiaoli Village belongs to the contract area of the 1st Battalion. When Xu Rui arrived, He Guangming was convening a meeting with his company and platoon commanders. Seeing Xu Rui coming in, He Guangming and a dozen company and platoon commanders quickly stood up and saluted Xu Rui.
Xu Rui returned the gift and asked: "Lao He, how is the situation now?"
He Guangming replied: "The little devils are not stupid. They have already transferred the generator set and two water pumps, and are now diverting water to pour into the tunnel."
"Diversion of water?" Xu Rui chuckled when he heard this, but didn't take it to heart at all.
Because when they first decided to build the tunnel network, Xu Rui and Wang Husheng had foreseen that the Japanese might divert water from the Mei River to pour into the tunnels, so they asked Mei Jiuling to design drainage channels in advance, through which the Japanese could be poured into the tunnels.
The water was diverted back to the Mei River, and the water outlet was hidden under the bed of the Mei River in the canyon outside the town. The Japanese couldn't find it at all, and naturally there was no way to block it.
However, this drainage system has not been tested in actual combat, and it is not known whether it can play its due role.
Xu Rui then asked: "Did the drainage system work? Is there any water accumulation in the tunnel now?"
"No." He Guangming immediately shook his head and replied, "The drainage system is in better condition than expected. Even if the little devils bring in two more water pumps, they won't even think about flooding our tunnels."
"You still can't be careless. After all, this is just the little devil's first attempt. Once it doesn't work, there's no guarantee that the little devil won't adjust more water pumps." Xu Rui thought for a while and then continued, "Otherwise, how many people would you send?
I personally go to the drainage ditch and keep an eye on it, and report it immediately if I find anything wrong."
"Yes." He Guangming agreed and immediately ordered a platoon leader to go to the drainage ditch.
Xu Rui added: "In addition, check the sealed doors of each isolation area again. The quilts must be prepared, otherwise once the little devil releases the poison gas, the poison gas cannot be sealed and leaks into the core functional area, and the consequences will be disastrous."
Preventing the poisonous gas from the Japs is the focus of defense in tunnel warfare. Mei Jiuling specially designed the entire tunnel network into a multi-level structure. There are separate isolation doors between each layer of tunnels. Once the Japs carry out a poisonous gas attack,
, just need to close the isolation door and cover the door with a quilt to effectively prevent the penetration of poisonous gas.
The functional area used for people to hide and live is hidden deep in the deepest part of the multi-layered tunnel.
"Don't worry, Captain." He Guangming immediately replied, "I have checked it again and again and there is absolutely no problem."
Xu Rui insisted: "Let's check it again to make sure nothing goes wrong."
"Yes." He Guangming said, "Check again to make sure nothing goes wrong."

Kawaguchi Heiji was already in a very irritable mood.
Every ten minutes, Kawaguchi Heiji would get off his armored command vehicle and walk to the five high-power water pumps that were roaring not far away. Yes, the Japanese army used two high-power water pumps to fill the water all morning, but it failed.
The tunnel was filled, so Kawaguchi Heiji ordered three more high-power water pumps.
Kawaguchi Heiji fixedly looked at the soft leather pipes extending from the five water pumps and extending into the Meihe River. He felt very confused in his heart. Why could the five high-power water pumps pump water at the same time and pour water back into the tunnel, but it could not fill the tunnel? In an instant,
Kawaguchi Heiji thought of a possibility, unless the Chinese built drainage canals in the tunnels!
Thinking of this, Kawaguchi Heiji immediately turned to tell Muto Akira: "Muto-san, there is no need to pump water and pour it back, because it is useless."
"Your Excellency, Commander, are you saying that a drainage system has been built in the tunnel?" Akira Muto pretended to be suddenly enlightened.
In fact, Muto Akira has long realized that the Chinese have built drainage ditches in the tunnels. Therefore, unless the amount of water you fill is so large that the tunnel drainage system cannot bear it, you will never be able to fill the tunnel. As for the tunnel drainage,
Only the Chinese know how much the system can bear, but it is obviously impossible to do it with just a few water pumps.
However, Muto Akira was not in a hurry to tell Kawaguchi Heiji.
Having said that, doesn’t it make Kawaguchi Heiji look very incompetent and stupid?
It was only now that Kawaguchi Heiji himself came to his senses and Muto Akira finally "suddenly realized".
Kawaguchi Heiji curled his lips and said angrily: "Muto-san, you don't need to pretend to be stupid in front of me. How can you not see that the drainage system has been built in the tunnel? In fact, I also thought of it, but I was just lucky and counting on it.
Five high-power water pumps can flood the underground drainage system, but now it seems that I was too naive."
After Muto Akira's scheming was revealed, his expression became a bit stern, but this time the flattery was just flattering.
Kawaguchi Heiji ignored Muto Akira's gloomy thoughts and said in a deep voice: "It seems that diverting water to pour water back will not work, so we might as well use poison gas, but we must do a good job of confidentiality, so don't notify the reporters accompanying the army."
"Hai." Muto Akira paused and asked in a low voice, "What kind of poison gas will be used?"
Kawaguchi Heiji thought for a while and said in a deep voice: "Just use the newly arrived Yellow No. 2."
"Hai." Akira Muto paused and said, "Use Huang No. 2 to carry out a poison gas attack."
Yellow No. 2 is Lewy's gas. Lewy's gas is a type of erosive poison that can cause the body's skin to rot. Without protection or timely treatment, the injured person will die due to respiratory tract and skin rot, and when he dies,
It is very painful and is one of the chemical weapons prohibited by international conventions.
Kawaguchi Heiji gave the order, and the Japanese took action immediately.
The Japanese infantry originally guarding near the tunnel entrance quickly evacuated, and Kawaguchi Heiji's armored command vehicle also evacuated to more than a thousand meters away. Finally, Muto Akira set up a cordon around the entrance.
Just as the preparations were completed, three trucks from the baggage team arrived.
The three trucks did not stop on the road, but drove directly into the restricted area.
The truck stopped, and dozens of chemical defense soldiers wearing protective nets and gas masks got out of the truck. After getting off the truck, these chemical defense soldiers carried out dozens of cylinders from the truck compartment.
The ten cylinders contained compressed gas code-named Lewis Gas No. 2.
In order to prevent the poisonous gas from being poured back into the atmosphere and to ensure that all the poisonous gas penetrates into the tunnel, the Japanese chemical defense soldiers also prepared two high-power fans. After connecting the power supply, the two high-power fans were aimed at the entrance of the tunnel and began to blow. Then the Japanese chemical defense soldiers
The soldiers carried the cylinder containing Louis' compressed gas into the tomb passage and opened the valve.
Once the valve is opened, yellow-brown gas gushes out from the mouth of the bottle, and then surges toward the depths of the tunnel under the blowing of a powerful fan.

The highly poisonous Louis Qi surged down the corridor and rolled towards the connection between the first and second tunnels. This connection was also the place where Takeo and the others on the mountain were attacked just now.
A dozen soldiers who were responsible for guarding the connection were nervously watching the two mice in the cage.
These dozen soldiers did not know why the battalion commander specifically told them to put two rats in the connection port, and repeatedly told them that once they found any abnormality in the rats, they would immediately close the tunnel between the first and second floors.
interface, and at the same time open the exhaust port on the ground floor.
Although more than a dozen soldiers did not know clearly, they did not neglect their duties.
In fact, it was Xu Rui who told him to put a few rats at the tunnel connection, because Xu Rui is a time traveler, and he knows that rats have a sense of smell that is ten times more sensitive than dogs.
When the dose of poison gas is not enough to kill the rats, the rats will become alert, scream and run around.
Time passes slowly in the silent waiting. In the depths of this dark tunnel, you can't tell whether it is day or night outside.
At a certain moment, a mouse in the cage suddenly screamed.
The dozen or so soldiers standing guard at first didn't pay much attention to it.
But less than two seconds later, the two mice began to scream continuously. While screaming, they slammed their bodies against the iron cage, trying to break through the iron cage and escape. A dozen soldiers first
Stunned, the squad leader who was the leader finally reacted and shouted: "Quick, open the vent on the first floor and close the entrance on the second floor, quick!"
More than a dozen soldiers immediately got busy. First, they moved away the bricks blocking the ventilation opening on the first floor, then climbed up the ladder from a hole that was only accessible to one person. After climbing up, they quickly lowered a turned-up door panel.
, first cover the door panel with a quilt, and then cover the quilt with sand.
That's right, the first level of the tunnel is at the deepest point underground, but the second level of the tunnel is above the first level of the tunnel.
The second floor of the tunnel is the battle area, with a large number of traps arranged inside. The third floor above the second floor is the functional living area.
This was also designed by Mei Jiuling, because building the first floor of the tunnel connected to the ground at the deepest point and connecting it to a special exhaust and drainage system can effectively resolve the enemy's water irrigation, poisonous gas and other attack methods, while being at the deepest level on the surface.
The shallow functional area can protect you from the threat of Japanese invaders. If necessary, you can break through the tunnel to save yourself.
