**********

In the White Twilight Mountain mine, the zombie group that was blocked soon began to dig a new tunnel.

At the same time, in the headquarters of the dungeon of White Twilight Mountain in the depths of the mine, Yin Xiuwen, the city lord of the dungeon, had also received the news of the collapse of the defensive line they had arranged at the entrance of the cave. He and his staff were shocked and incredulous.

"What! How so! That's impossible! Didn't you just report that everything was working well with the defense line at the entrance of the cave? How come it was that less than 1 minute had passed, and the zombies had suddenly broken through our defenses! ”

"City ...... City Lord, the zombie hordes have dug holes in, they have bypassed our defense line and suddenly appeared behind us! Brother Seventy or Eighty didn't have time to escape, he had already died! ”

"Dig a hole!" Yin Xiuwen is like a thunderbolt from the blue.

The reason why they insist on staying in the mine and not moving is not because they feel that there is only one entrance in the mine and it is easy to defend. But now the zombies can actually dig holes, doesn't that mean that the entire dungeon zombie group can enter and exit at will!

In fact, this is not something that no one on their side thought of before, but the dungeon is their hard work and their hope for the future, so everyone doesn't want to believe it.

However, now that it has become a reality, it has left most people in despair. There is only one entrance to the mine, which means they have no way out!

In an instant, remorse and fear all came to my heart, why didn't I listen to the advice of the Iron Castle and evacuate here in the first place!

The soldiers who came back to report saw that Yin Xiuwen was stunned, so they continued to ask anxiously: "City Lord, now that the zombies have started digging holes again, they probably want to bypass our second line of defense again." What do we do now? ”

Hearing the soldier's words, Yin Xiuwen came back to his senses, with a solemn face, he lowered his head and thought about it, but soon raised his head again, and he asked the staff officers around him: "Let's tell me your opinions." ”

A staff officer first said: "City Lord, why don't you send the fourth and fifth squads defending the rear on the two forked main mine roads to support the front line?" As long as there are enough troops, they may be able to hold the mine tunnel and prevent the zombie hordes from rushing out of the newly dug tunnels. ”

But someone immediately expressed concern: "But this is also dangerous, what if the zombie group only digs two tunnels to come in?" If there is a tunnel that happens to appear behind our troops, then they may be like the brothers before them, flanked by a large number of zombies, and they will be attacked on their backs. What's more, in this way, their supply will be interrupted. That's definitely dead and alive! With so many troops lost, what else do we use to defend? ”

So someone suggested: "Then the city master should we let the brothers in the second line of defense quickly withdraw first?" We're going to retreat to the deepest part of the mine to defend it. Maybe the zombies can't dig that deep! Without reinforcement, it is quite possible that the tunnel will collapse halfway through the digging. And there is no map in the mine, there is no locator, the zombies are not so easy to dig in the right place, too deep and too shallow, or too left and too right, may miss our mine. Maybe they won't be able to dig it up in a few years! ”

When some people hear this suggestion, they can't help but think that it seems feasible.

But immediately someone who understood objected: "You are stupid, if we give up the mine in front, the zombies will not drive straight in, and directly chase us to the depths of the mine, and then wait until we can't beat it, and then use the trick of digging a hole to spare our defense line?" In this case, they will only have to dig a distance of twenty or thirty meters. And we gave up so much of the defensive space in front of us! ”

He continued, "So, I think we should immediately send a large number of people to the front and put their ears to the walls of the mine to listen to the movement inside, so that we can roughly judge where the zombies are digging and where they will come out from by the sound of zombies digging into the holes." As long as we prepare in advance so that the zombies can't attack us suddenly, I believe that it should be easier to defend against such a newly dug tunnel than the main mine. Because of the newly dug tunnel, it is impossible to dig too large without the assistance of machinery and equipment. ”

Someone agreed: "Yes, yes, that's really good advice." ”

Yin Xiuwen couldn't help nodding, he agreed: "Immediately order the fourth and fifth squads defending on the two bifurcated main mine lanes to rush to the second direction to support the first and second squads." Let them follow Staff Officer Liu's method, spread them all out, use the walls of the mine to listen to the direction of the zombie group digging holes, and be ready to fight at any time. At the same time, all the residents of the dungeon were ordered to collect all available materials, logs, iron plates, iron fences, and iron gates, and after predicting the place where the zombies might dig through the mines, they asked everyone to immediately reinforce the walls of the mines. Plug them and block them. ”

"Yes!"

At the same time, in the back mountain of White Twilight Mountain, the soldiers of the 1st Engineer Battalion of the Self-Rescue Army were digging tunnels with all their might.

Although they had the help of large machinery and equipment, the tunnel was too long, so they had to dig and reinforce as they went, and it only took half an hour to dig 60 meters.

Under normal circumstances, such a speed is actually quite fast.

However, the commander of the engineer battalion is still urging everyone to continue to work hard to speed up. Because he had just received the news that the first line of defense in the dungeon of White Twilight Mountain had collapsed under the attack of zombies. A large number of zombies have poured into the mine from the hole.

Although at the moment it seems that the advance has stopped again. However, the mine has also resumed transporting soil to the outside world. This means that the zombie hordes have started digging tunnels again.

*********

Less than 20 minutes followed. The zombie horde's earth-raiding excavation once again reached the second line of defense in the dungeon of Twilight Mountain.

This time, due to the lack of interference from the artillery fire of the self-rescue army, the speed of the zombies digging the tunnel was much faster than before.

However, their actions were indeed detected in advance by the people in the dungeon of White Twilight Mountain, so before the zombie group completely dug through the walls of the mine, the survivors who had been waiting in the surrounding area immediately rushed up under the command of Yin Xiuwen, and used logs, iron plates, iron fences and other things to reinforce the walls of the mine.

"Dang!"

The zombies that dug through the walls of the mine knocked a shovel onto an iron fence. Although the muck and lime on the walls of the mine have fallen, the iron fence is not so easy to cut down.

So the guards of the White Dusk Mountain Mine who were ambushed around immediately passed through the newly dug hole of the zombies and aimed at a "ping-pong" shot in the tunnel. Finally, the zombies who were digging the tunnels were eliminated in the tunnels.

As long as it doesn't appear out of nowhere, such a newly dug narrow tunnel is indeed relatively easy to hold.

But zombies don't give up so easily. They don't work here, they can go in other directions. The person in charge of listening soon heard the sound of zombies digging again from the walls of the mine. And in this regard, they have no choice but to defend passively.
