The soldiers relied on the grooves in the city wall and the reserved fire points to attack, while the rest of the city was mostly cover, used to resist the poisonous needles and venom of the insects, but even so, the eyes were still rapidly consumed, because the venom had a strong corrosive effect.

Occasionally, after some soldiers are stained with venom, the extremely corrosive nature will cause the parts stained with venom to rot quickly, and most of the iron gates of the first line of defense are quickly corroded by this venom, not to mention people.

Faced with such a situation, Zhang Zhen could only order the snipers behind him to give priority to sniping those insects that carried out acid attacks, so that the attack on the bunker was indeed a lot less, but the snipers were originally responsible for those high-level monsters, those monsters that mutated once or even twice, especially the monsters that mutated twice, those ordinary firepower, they couldn't be hit at all, and they needed sniper rifles to attack.

And in the center of the second line of defense is a diamond-shaped aurora tower, after the constantly firing aurora sweeps, the insect swarm is also turned into ashes, but most of the targets of this tower are also those high-level monsters, especially the monsters with heavy armor, are the targets of the diamond-shaped tower.

The core area is extremely well defended and powerful for each base, and the Steel City is naturally no exception, but after the core area is evacuated, there are almost no people here, but those equipment are still there, and Zhang Zhen also found some good things from the spare arsenal laser cannon.

This thing can be said to be an advanced version of the heavy armor-piercing machine gun, because the bullets it fires are not ordinary bullets, but Aurora.

And the aurora has a strong penetration, which is almost a nightmare for those monsters, and in all the kills so far, the laser cannon has killed more than 50% of the monsters, and it can be said that half of the monsters have died under this kind of gun.

And this kind of gun, in the entire No. 2 defense line, there is one every 10 meters, forming a tight fire network to shoot cross-fire, and those monsters and bugs their attacks are almost endless, and they continue to die on the way to the charge, so they also slowly form a pile of corpses.

As time passed, the corpse pile gradually gained a certain size, and this corpse pile also blocked the attack of the defenders, after all, the original defense line was a flat upward and downward oblique shot.

However, the rise of the corpse pile made it impossible for some monsters to be attacked, which led to the fact that that part of the area had to advance more than the other parts of the area.

At the same time, it also increased the danger even more, Zhang Zhen naturally discovered this kind of change, but those corpse piles are some distance away from Line 2, and if you want to clean them up, you can only blast them at close range, because even if the long-distance bazooka hits the corpse pile, at most it will reduce the height a little, and it will not cause much harm.

Because many of the monsters in those poems are secondary mutations, and the carapace of the secondary mutated monsters cannot be threatened by the bazooka alone, which also leads to the fact that the bazooka cannot remove those corpses from a distance.

However, one of the members of Zhang Zhen's team, his bazooka is a blood energy weapon, and he can still effectively remove those pairs, but there are too many corpses piled up, and one person can't clean them up at all, and if it goes on like this, it will not be a way sooner or later.

If you let the warrior go down and blast, you will definitely die a lot, because those monsters that shoot poison needles and venom are not vegetarians, and if you want to really eliminate them without injury, he is the only one who can do it.

Looking at the slowly advancing monster group, as well as the soldiers around it, whose foreheads had begun to sweat, the silent Zhang Zhen didn't say a word, turned his head and walked to the back, although the team members were a little strange, why did the captain go to the back, but they didn't have time to take care of anything else, because the monsters were slowly advancing, and they had to attack all the time.

And when Zhang Zhen appeared again, his body was already full of high-explosive bags, this explosive has a strong impact, although its own power is not very large, but its impact is enough to blow up those piles of corpses.

Without saying a word, Zhang Zhen jumped down from the defense line and sprinted towards the monster group, and the monster bugs behind naturally discovered this human who jumped out of the defense line, and those bugs who fired poison needles and venom in the back immediately set fire to this person.

Because most of the other people are behind the bunker, it is not easy to attack, and this person jumps out of the defensive line, and there is no cover, so he naturally becomes the target of the insect attack.

But obviously, they underestimated their target, no matter what, Zhang Zhen is also a person who has reached the second mutation, how can he be attacked by the poisonous needles of those mutations or even ordinary monsters, so he keeps dodging left and right, but no matter how strong a person is, he can't stand the large number, in the face of the attack on him by the insect poison needle venom in the sky, Zhang Zhen can only show a wry smile, and curse in his heart?

But there was no way but to dodge desperately, but he was almost attacked several times, but he was narrowly avoided.

Zhang Jing naturally saw the captain's bad situation, and even if he took over Zhang Zhen's command responsibilities and gave an order,

Cover the captain forward.

After the order was given, half of the soldiers abandoned the melee regrouping that was constantly feeding the position, and instead aimed their fire at the bugs that were firing long-range attacks in the distance.

Although the close swarm in front of them was slowly advancing due to the weakening of firepower, and was not in a stalemate, the bugs that fired the venom of the needle in the distance were all attacked and interfered with.

For a while, the pressure faced by Zhang Zhen was greatly reduced, and Zhang Zhen naturally knew that this situation would not last long, no matter what, if the insects in front of him approached the position, then it would basically be over.

At such a critical moment, Zhang Zhen naturally did not miss the opportunity to move forward quickly, and quickly flashed one insect after another around him, not entangled with them at all, when he came to the edge of the corpse pile.

He threw the bomb in his left hand to the bottom of the pile, and then quickly ran to the left, throwing the bomb on his body to the bottom as he ran.

And it didn't take long for a series of explosions to sound under the pile of corpses, those corpses were not affected much, but the corpses that had been piled up were dispersed by the impact of the explosion, this kind of bomb was specially invented to deal with the current situation.

You must know that when defending the base in the past, when encountering a large area of monster attack, it is inevitable that such a thing will occur, but it will directly threaten the soldiers on the city wall once it is too high.

In order to solve this method, this kind of bomb with little power but strong impact has been developed in the Hope General Base, and this bomb is also known as the Eraser, as the name suggests, it is to smooth out the pile of corpses.
