The dark beast excavated the space and slowly advanced towards the first front, once the hole was dug to the battle line, the space for direct contact would become larger, and Li Zhong and their front would immediately face a catastrophe, and it was absolute to be broken through.

At this time, under the command of the three mercenaries, those militiamen began to retreat in an orderly manner, retreating towards the second line at a rapid speed, and remained calm while being nervous.

There are many passages in the entire settlement, and a lot of positions are arranged, as long as they are steady and steady, it is enough to support a few days, and the only thing they are afraid of now is that the crystal coins are exhausted, which is a big problem.

However, at this time, the old village chief had gathered all the people in the settlement and asked them to donate all the crystal coins as ammunition, and they had already collected millions of crystal coins.

At the time of crisis, no one would care about the dark crystal coins, and they donated their crystal coins one after another, and after the people selected by the village chief registered, they were directly put into the ammunition depot to ensure that the front line had enough crystal coins to consume.

At this time, not only Li Zhong was fighting, but the militia behind the position was not idle, and was in the deepest tunnel, continuing to dig the road to the depths, constantly arranging battle lines and checkpoints, in order to delay time at the moment of crisis.

In the event of an unfavorable battle ahead, they can immediately retreat and prepare the fighters for the advantage of the terrain.

This is the experience of countless old people, and the reason why there are so many caves in the entire underground settlement is because of this, this tactic has been tried countless times.

At this time, Li Zhong and the three mercenaries stood on the front line and took on the task of breaking off.

Jace shouted, "You three, get ready to retreat, I'm going to use my guns." ”

Li Zhong was invincible with two guns, blocking the space, and no dark beast could rush through his guns safely, hearing Jace's words, he nodded, and began to prepare to retreat at any time.

At this time, Jace rushed out in an instant, directly in front of the dark beast, and Li Zhong and the others seized the opportunity and instantly began to retreat, heading towards the second front.

"Bang Bang Bang"

In the entire cave, he suddenly remembered a dense gunshot, Li Zhong glanced behind him slightly, and was immediately startled.

I saw that Jace's whole person turned into a spinning top, and countless black lights burst out from where the top was, densely spread in all directions, and every inch of space was densely packed with charged bullets, and he frantically fought against the dark beasts that came to him, and he was in danger for a while.

As Li Zhong and the three of them came to the second front, everything had already been arranged here, hundreds of militiamen were densely packed behind the bunkers, with encore rifles, and black lights flashed, hitting the dark beasts who were about to cross the first position.

At this time, Jace had already finished all the bullets in his hand, and the surrounding area was emptied by him in an instant, seizing this gap, Jace frantically rushed towards the second front.

Li Zhong set up his two guns and kept shooting at the pursuing dark beasts behind Jace, but none of them missed.

Finally, as Jace jumped into the second front, Li Zhong and all of them safely retreated to the second front, and by this time the dark beasts had crossed the first line and were steadily advancing towards the second front.

Time passed quickly, and bloody battles were staged throughout the cave, Li Zhong and the others had retreated to the commercial center, the bunkers arranged here were no longer enough to rely on, there were too many dark beasts, and the walls of those bunkers might not be able to resist, and they would shatter when touched.

At this time, there were more than hundreds of dark beasts that died in the hands of Li Zhong and others, but there were also dozens of militiamen who died in the hands of those dark beasts with long-range attack capabilities.

At this time, I only heard Akins shouting: "You hurry up and inform everyone, all enter the longest passage that is still being excavated, we can't divide our forces, this time the dark beast tide is too terrifying, everyone speed up." As Akins's words fell, the people of the entire settlement, led by the old village chief and the village chiefs of each settlement, began to retreat in an orderly manner, carrying their own space backpacks one by one, filled with supplies, and headed towards the longest passage.

This passage is the tunnel where Li Zhong's stone house is located, which is two kilometers long, three meters high, and about four meters wide, suitable for people to take shelter into, and also suitable for arranging battle lines.

Li Zhong and the militia were dead on the road in the commercial center at this time, and a large number of dark beasts gathered in front of them, and they continued to charge the position one by one, but under the shooting of Li Zhong and others, they were never able to break through.

Li Zhong's eyes could clearly see that in the depths of the cave, dark beasts were digging caves on both sides, trying to open the passage to Li Zhong and them, but these dark beasts didn't know.

The rocks here are all connected to the black iron mine, which is very hard, and humans have all kinds of tools to dig easily, but the dark beast can only rely on its own claws, and will immediately fall into a long battle.

As the minutes ticked by, three days had passed since the battle began, and the militia in the settlement had rotated seven times, and hundreds of people had died here, and their bodies had been transported back to the deepest part of the cave.

In this battle, most of the dead were fought in the commercial center, where the terrain was open and the bunkers were fragile, and that battle could be said to be the most dangerous, except for Li Zhong and the three mercenaries, there were less than fifty people who could safely retreat to the cave battle line.

Li Zhong and the three mercenaries were already quite tired at this time, and they all relied on the support of resuscitation potions.

Li Zhong took a bottle of white resuscitation potion, and a surge of power poured out from his body, allowing him to return to his peak realm again.

However, Li Zhong clearly felt the mental exhaustion, which could not be compensated by the medicine.

Li Zhong has already had a bad premonition in his heart, this battle has lasted for too long, and now the entire battlefield relies entirely on the three mercenaries and Li Zhong's magical marksmanship to remain undefeated, but now Li Zhong has reached the limit due to mental exhaustion, and the phenomenon of marksmanship mistakes has begun to appear, which is not a good sign.

At this time, Akins also saw Li Zhong's state, and said to Li Zhong with a solemn expression: "Li Zhong, you go to the next line of defense to sleep, you must not lose your combat effectiveness, leave it to us here, the militia here have adapted to the battle, and there is no problem in supporting you until you wake up." ”

Hearing this, Li Zhong nodded, but did not speak, he knew that this had to be the case, otherwise once he lost his combat effectiveness, the consequences would be the same, and it was better to rest than this.

As Li Zhong turned into a black shadow and disappeared into the tunnel, the pressure here suddenly increased, and one by one the dark beasts lost Li Zhong's accurate shot, and immediately advanced twenty meters.
