Independent Brigade, the eastern defense line of the city.

In order to prevent the little devils from digging tunnels and blasting from underground, at the beginning of the design, Liang Xiaolong took this into account, designed a lot of listening holes in front of the entire defense line, and installed a lot of listening devices.

On the part of the little devil, he has always thought that he has done a good job of secrecy, and he never thought that he was discovered by the Independent Brigade a few days after the tunnel was excavated, and after a few days of monitoring, the Independent Brigade has determined the specific location of the Little Devil tunnel.

According to Ye Feng's request, Liang Xiaolong personally came to the defense line in the east of the city to make relevant deployments, Liang Xiaolong had already arranged for the soldiers, and was digging the aqueduct, and at the top of the Little Devil Tunnel, he was carefully digging the shaft.

The aqueduct will be directly connected to the reservoir, the reservoir has been repaired a long time ago, as long as the aqueduct is connected to the reservoir, a large amount of cold pool water will flow directly down the aqueduct to the shaft, once the shaft is opened to the tunnel of the little devil, a large amount of pool water will be directly poured into the tunnel that the little devil is digging.

In several hidden places, several one-meter-square shafts have been excavated, and the excavation depth has been nearly twenty meters, and at the bottom of each shaft, the excavating soldiers are cautious, digging out the soil and hanging it with a dustpan.

"Squad leader, I estimate that two or three meters further down will dig through the tunnel of the little devil." Next to the shaft, a soldier whispered to his squad leader while hoisting up the dirt at the bottom of the shaft.

The squad leader took a dustpan full of soil, poured the soil a few meters away, and said: "Chief Engineer Liang has already come to see it, and it will be dug through if it is about three meters down." ”

The warrior who had just whispered looked at the aqueduct that connected the shaft, which was about one meter wide and almost one and a half meters deep, and two soldiers could easily pass side by side in time.

"Squad leader, you said, with such a wide aqueduct, the water from the reservoir that was brought over is not rushing down."

"That's, so, let's hurry up and dig the shaft and drown these little devils then." The squad leader also whispered.

Underground tunnels.

Motoji Kuroki had already looked at a few places where there was a slight seepage, and seeing that the soil on the top of the tunnel was very soft under the infiltration of the rain, Motoji Kuroki was a little worried, and prayed in his heart that it would not collapse.

However, the little devil doesn't want anything to happen, so he just comes.

"Boom!"

In the depths of the tunnel, there was a faint sound of a collapse, and when he heard this sound, Motoji Kuroki's heart tightened, and he thought in his heart, it was still a collapse.

In order to ensure the speed of excavation of the tunnel, after the tunnel was dug, it was basically only reinforced with some wood, and no cement was used at all.

"Let's go, let's go and have a look."

Motoji Kuroki took a few little devil officers and hurriedly walked to the depths of the tunnel, turned into a branch tunnel less than a meter wide, and walked less than a hundred meters, and the front was all blocked by mud.

"Dig this place up!"

Motoharu Kuroki immediately instructed the little devils to dig up the collapsed soil, there are a lot of little devils working in this tunnel, and the ventilation conditions in the tunnel are already poor, if this place is blocked again, don't wait for one or two hours The little devils in it will all suffocate to death.

The little devil was in a hurry, with all hands and feet, and it took a lot of effort to dredge the soil of the collapse, at this time, more than an hour had passed, and more than 20 little devils who were blocked inside were rescued after the worst.

Seeing that these little devils were rescued, there was basically no major problem, but it was probably due to a temporary lack of oxygen, and his face was a little ugly, and Kuroki Motoji breathed a sigh of relief.

Then, Motoharu Kuroki checked the location of the collapse again, the situation was not very serious, and he commanded the little devils to reinforce it, and Motoji Kuroki was ready to leave the tunnel.

"Your Excellency Kuroki, it was really dangerous just now!" The little ghost next to him Shaozuo was obviously apprehensive.

"Let's go, let's get out of the rut and breathe." After staying in the tunnel for so long, Motoji Kuroki may be bored and panicked, or he may feel dangerous and don't want to stay any longer.

Shaozuo, the little devil who had already wanted to get out of the city, immediately felt light in his heart, and quickly agreed: "Your Excellency Kuroki, then let's hurry up and get out of the city, where is Your Excellency the division commander waiting for our situation report." ”

The newly appointed division commander of the Sixth Division, Ushijima Man, attaches great importance to this tunnel, and today, he came here again and waited for a report on the situation at the entrance of this tunnel.

Motoji Kuroki and the little devil Shaosa were about to turn around and leave, but at this time, Motoji Kuroki saw a large amount of dirt falling straight down from the top of the tunnel not far ahead.

Is it going to collapse again?

However, it didn't take long for Motoharu Kuroki to take the idea out of his mind, and it didn't look like a landslide, but it looked like someone was digging something at the top of the tunnel, and it was about to be dug through, which is why so much earth fell.

The tunnel he designed is not a double-decker tunnel, only one layer, how can there be people on the top of the tunnel, but soon, Motoji Kuroki thought of something, and his face turned white in an instant.

The little ghost next to him, Shaozuo, saw that Motoji Kuroki's face suddenly became so pale, and his eyes were full of fear, and he couldn't help but ask anxiously: "Your Excellency Kuroki, what's wrong, is it going to collapse again?" ”

"Run, Run!!"

This is much more serious than the collapse, Motoji Kuroki shouted in horror.

Hearing Kuroki Motoji's shout, many little devils who were working were puzzled, Mumu looked at Kuroki Motoji, and thought to himself, what's wrong.

Motoharu Kuroki has a lot of experience, and when he thought that someone was digging on top of him, he immediately thought that it must be the Independent Brigade that had discovered his tunnel, and was ready to dig a hole in the top of his tunnel to fill it.

The tunnel of the little devil is very long and narrow, there are a lot of little devils in it, because the tunnel is manual work, excavation, transportation of soil, tunnel reinforcement, a large number of little devils are needed, this tunnel of two or three kilometers long, from the original hundreds of people to the present thousands of little devils.

Inside the main tunnel, there were a large number of little devils, one next to the other, one or two meters apart. These little devils are in a long line, and they are relaying the excavated earth, which is very efficient, but if the tunnel is filled with a lot of water, the little devils in the tunnel will be destroyed.

It was precisely because of this that Motoji Kuroki turned pale and screamed in horror.

Motoharu Kuroki had just shouted a few times, and the top of the tunnel where the dirt was falling down in front of him was quickly dug through, and a large hole appeared, and strong sunlight shone down from the top of the cave.

With this strong sunlight, the little devils found that a soldier wearing a national army uniform, holding a small shovel, smiled at themselves, and then, in the blank eyes of the little devils, the national army soldier quickly climbed up.

The little devils found that at the top of their tunnel, there was a deep shaft about twenty meters deep and about one meter square in area.

At this time, the little devils who saw this situation understood, and immediately screamed in fright, threw away the tools in their hands, and rushed to run in the direction of the tunnel exit.
