Boom -

Under the huge explosion, the entire tunnel was shaking.

Because it was feared that successive explosions inside would cause the tunnel to collapse. So most of the area in front of the tunnel is dominated by machine guns.

But from the 6,000-meter section, range weapons such as grenades, howitzers, and individual rocket launchers have become the mainstream attack methods.

On the third day of defense time, the lizardmen had advanced to 6,000 meters.

These lizardmen, who don't care about death at all, don't have a rally, and will attack as soon as they reach a point of fire that they can forcibly destroy.

With this incessant onslaught, the missionaries, who are always in a combat state, have begun to experience a severe decline in physical strength. Although only missionaries within 100 meters of the Lizardman can effectively attack, this does not mean that the Lizardman can fall asleep without attacking the range that he can defend.

In the never-ending sound of gunfire and disgusting pungent blood, no one can be completely unaffected.

Physical strength is only one aspect, and the mental state of the tasker in the tunnel is much worse than the physical state.

The lizardmen were able to enter the middle of the tunnel unscathed, enough for them to guess what was going on with the defenders in front of them. If it weren't for the fact that the lizardmen hadn't heard anything terrifying in the mezzanine, it would have been impossible for these taskers to continue manipulating their weapons to attack.

Both physical and mental problems have directly caused the lizardmen to go from the cost of more than a dozen people to destroying a firepower point to four or five now, and the proportion is still decreasing rapidly.

It is only now that the appearance of range-attacking weapons in the tunnels has stopped the trend of getting worse.

Taskers with area weapons can simply see the lizardman, pull the trigger, reload, and pull the trigger again.

It seems to be a coincidence, as when the lizardmen attacked the area with a range of weapons, a boundless sea of black just came to the ruined square.

At the mouth of the tunnel, the black sea rushed into it in the most turbulent form, as if it had encountered a small dry aqueduct.

After flowing out of a calm distance of more than 6,000 meters, the lizardmen in the front row were violently attacked, and in just a few minutes, the tunnel that was already full of lizardmen's corpses was completely blocked by relatively intact corpses. The team of lizardmen behind them overlapped, pushing the piles of corpses forward.

The thick pile of corpses became an excellent barrier to block attacks, and the tasker had to frantically beat the corpses into meat sauce to attack the lizardmen behind. But this is of little use, as even if the lizardfolk who followed the corpse are killed, their corpse will be used as a shield by the lizardfolk further behind.

This brutal attack was slow, but unstoppable, advancing little by little, until at 6,500 meters of the tunnel, a larger range and more powerful weapons appeared one after another.

Whether it was the corpse used to block the attack, or the lizardman behind it, it was blown to pieces in an instant.

If the lizard reverts to its original attack pattern, it will rush forward at high speed. Then these weapons with a slow frequency of attack are simply useless in front of them.

But they seemed to have fallen into a state of inability to think, and they still used a dense cascading formation to move forward slowly.

And they also seem to be oblivious to the additional effects of weapons that increase in power......

In the continuous explosion, the overall stressed structure in the tunnel has been deformed, and finally in another explosion, the tunnel collapsed, starting from the rock that was continuously attacked by explosive weapons at 6,000 meters and became full of cracks, to the collapse induction point at 7,000 meters. The lizardfolk of a full kilometer were all buried in countless steel and rock.

An hour later.

"Alright." Looking at the still calm picture in the monitor and control, Qiu Yu breathed a sigh of relief, "Judging from the data collected earlier, it will take them at least 1 day to dig up here. ”

But as soon as Qiu Yu's words fell, the picture on the monitor made his face turn snow-white.

It was 7,100 meters away, and a steady stream of lizardmen appeared in the tunnel behind the collapsed blockage.

Qian Xiao's face was even whiter than Qiu Yu's, "How is it possible, could it be that they came from the mezzanine?" ”

"No, if I had gone through the mezzanine, my alarm would have gone off and they would have been on the platform." Qiu Yu immediately denied it.

"Their bodies have a lot of intensity. If you combine this...... "Qiu Yan drew a thick gray line representing gravel on the computer screen, and then used a thin red line to run through this thick line, "Their action just now was to start from 6,000 meters of the tunnel and use corpses to build a corpse path in the tunnel. The crumbling rock failed to crush all the bodies that were thick enough. It was from the tunnel made of these corpses that the lizardmen gnawed a way out. ”

Qian Xiao smiled and said, "How is this possible!" ”

Qiu Yan shook his head, "This is the most reasonable answer I can think of, but since it has already happened, there is no need to go deeper, the key is that this situation explains ......"

"It shows that when they first entered the tunnel 6,000 meters, I thought that the elaborate layout had already been seen through. And their response didn't let me see through ......" Qiu Yu looked at the almost ineffective defense at the end of the tunnel, "It seems that there is already a pretty great lizardman commander who has taken over the command of the battle against us. ”

As if to interpret Qiu Yu's words, the alarm arranged in the mezzanine of the tunnel also sounded.

"Even the little tricks in the mezzanine have been seen through......"
