The zombie group that was successfully stopped by the people in the dungeon of Twilight Mountain did not give up the attack so easily.

Anyway, as long as the underground space can be dug up, it can go in any direction. If the hole is stopped, they can continue digging backwards.

After only ten minutes, they continued to dig more than ten meters deeper into the mine. And ready to break ground again from here.

Of course, the people of Twilight Mountain were also prepared in advance.

Blocked twice, the zombie hordes begin to change tactics, and they begin to dig upwards in an attempt to invade from the top of the mine.

Yin Xiuwen and the others were shocked when they learned of the situation.

Because there was no preparation in advance, the top of the mine could not be reinforced. And obviously, intrusions from the top of the mine will also be more difficult to defend against.

So he immediately ordered everyone to retreat and move to the third line of defense.

Sure enough, in the process of their hasty retreat, the zombies had already broken the roof of the mine.

The defenders of the dungeon of Twilight Mountain, who were passing below, immediately raised their guns and opened fire. But it still couldn't stop the zombies from falling from the roof of the cave like dumplings.

But fortunately, this time, due to the timely retreat, no one was trapped in the second line of positions.

As Rao did, the people who fled back to the third line of defense had begun to become very frustrated. The first line of defense was broken, and the second line of defense was still lost after some effort. So what is the use of them retreating to the third line of defense? It's not the same as it will be lost!

More and more people are finally realizing that the Iron Keep warnings are right. More and more people regret their contempt and indifference to the Iron Castle.

However, there is no such thing as regret medicine.

The zombie attack soon began again. This time, too, they began digging again after dropping the corpses full of caverns. And it was dug directly from the top of the mine.

"Quickly prepare to strengthen the roof of the cave, put the iron mesh and logs on the top, and support it with logs below."

Yin Xiuwen hurriedly gave orders to the survivors, this time, they had prepared ladders and tripods and other tools, so that their people could climb to the top of the cave and reinforce the top of the mine.

Ten minutes later, the zombie horde once again successfully dug up the position where it was ready to raid. And this time the zombie herd is three tunnels digging at the same time.

Although the locations where these tunnels appear, they all encounter the reinforcement layer set up in the dungeon of Twilight Mountain.

However, this is not the case before. The reinforcement effect of the roof of the cave is not as good as that of the other directions. After only a few impacts, the iron mesh supported by the log on the roof of the cave has already shown a tendency to loosen.

Ten minutes later, the reinforcement layers at the exits of the three cave roofs were already a little crumbling. Yin Xiuwen had to order the troops to retreat again.

Only this time, there were already two forks in front of them. And in the two bifurcated main mines, there are survivors who need to be protected.

Yin Xiuwen reluctantly divided the troops into two and asked them to defend one side.

By this time, the people in the dungeon of Twilight Mountain were basically desperate.

Lost three lines of defense in a row. And even with the third line of defense where all their forces are gathered.

So what should they do after the next two divisions?

But at this moment, there was a sudden sound of continuous mechanical roar behind the mine on the left.

"What's going on! How can there be a machine sound in the back? ”

Yin Xiuwen asked suspiciously.

He immediately sent someone to the back to check.

After a while, the man who sent out ran back in surprise, and he was followed by many heavily armed soldiers.

Just when Yin Xiuwen and they were puzzled.

The people who came back from the dungeon of White Dusk Mountain reported to Yin Xiuwen and them in ecstasy: "Great, city lord, we are saved!" It was the men of the Iron Castle, and they had opened a tunnel from the back hill to enter the mine. Now they are already organizing the evacuation of the people behind them! In addition, they sent a battalion of combat troops to assist us in strengthening our defenses. This is Battalion Commander Liu of the Steel Fort Self-Rescue Army! ”

Yes, after nearly two hours of hard work, Huang Chengcheng and the others finally completed the task of opening up the mine.

Yin Xiuwen was overjoyed, he couldn't believe it, so he repeatedly confirmed: "What! It's true! ”

Battalion Commander Liu of the Self-Rescue Army stepped forward and saluted Yin Xiuwen and said, "Hello, I am Liu Lei, Commander of the 1st Battalion of the 2nd Regiment of the Steel Fort Self-Rescue Army, and we are ordered to come to support you!" Assist you in evacuating. ”

Hearing this, the guards of the surrounding White Dusk Mountain dungeon guards broke out into earth-shattering cheers!

They couldn't have cleared enough about the strength of the Self-Salvation Army. The zombies in all the surrounding villages and towns were wiped out by them. Simply invincible! With their help, the stones in everyone's hearts finally fell to the ground.

"Thank you, Camp Commander Liu, thank you!" Yin Xiuwen stepped forward and shook Liu Lei's hand excitedly.

"You're welcome. Everyone is human, and our castle commander said that we must not watch so many of you die under the mouth of the zombies. ”

Next, Liu Lei waved his hand, and immediately let the soldiers of the Self-Rescue Army who followed him enter the position of the garrisons of the dungeon of White Dusk Mountain.

However, at this time, Yin Xiuwen suddenly thought of something, and he immediately said anxiously: "It's broken!" Fast! Hurry up and tell the people in the mine next door to move here immediately! ”

However, it seems that it is too late to transfer. The horde of zombies had already begun to attack, and they soon filled the open space in front of the two main mines. There was no way for the people on the other side to evacuate.

So Liu Lei immediately asked Yin Xiuwen to take him to the back of the mine and found Huang Cheng, who was organizing the evacuation of the survivors. Yin Xiuwen excitedly reported the situation to him.

Yin Xiuwen finally cried and pleaded: "Camp Commander Huang, please help us think of a way to save those people in the mine next door to us!" It's because I didn't listen to your advice that I got into today's situation, it's me who is confused, it's me who is sorry for them! ”

"1 Company Commander! 1 Company Commander! ”

After listening to Yin Xiuwen's words, Huang Chengcheng immediately shouted loudly to the commander of the 1st company.

"Battalion commander! What's the matter? ”

"Someone is stuck on another mine, can you dig another tunnel from this side? Rescue the survivors in the mine on the other side. ”

"Yes!"

The commander of the 1st company saluted and immediately spread out the map of the mine on the ground. Try to find a suitable excavation site on the map.

Soon, they found a location on the map that was closest to the other side of the mine.

"Battalion commander, you see, it seems that the digging from the end of the No. 12 branch road marked on the map seems to be the most recent. It is less than 30 meters to the No. 25 branch of the next mine. But battalion commander, we're probably a little too slow to move the excavation equipment back into the mine and erect it. We can only dig by hand, maybe a little faster. ”

Huang Chengcheng immediately asked, "How long will it take?" ”

"About 30 minutes."

Huang Chengcheng nodded and said, "Understood, dig immediately." I'll ask the people from the 2nd Company to help you reinforce the tunnels and transport the muck, and you just have to dig as fast as you can to the side of the 2nd main pipe. ”

"Yes!" The 1st company commander received the order.

"Thank you!" Yin Xiuwen was extremely moved.

Huang Chengcheng said: "These are all as they should be. City Lord Yin, you should continue to organize the survivors here to evacuate here quickly, we have a car waiting for you outside, and we can send you to the Steel Citadel for refuge. ”

Yin Xiuwen smiled very ashamedly and said, "Hehe, don't call me any city lord, the dungeon of Twilight Mountain was beaten like this by zombies, I don't have the face to continue to be the city lord at all, and there will be no more dungeons in Twilight Mountain in the future." I only hope now that I will have time to rescue our people who were trapped on the side of the main Mine Tunnel 2. Let me feel a little less guilty! ”
