Just when Gu Hongbo gradually mastered the rhythm of the battle, there was a lot of change, and I saw a burst of chaos in the corpse group, a mutated zombie the size of a car, the flesh on its body was piled together, like a giant beast with rolling flesh, the head was still of normal size, and there were piles of sarcomas on the back, and the appearance was very disgusting. ←，

It traveled extremely fast, landed on all fours, and rushed towards the battle line half-crawling and half-running, trampling the zombies that stood in its way, and its huge body crushed their bones and made a creaking sound.

"It's... What kind of monster is this? ”

The faces of the officials in the watchtower are all green, this boundless tide of corpses is already a nightmare, and now such a monster has appeared, I really don't know if the city wall can withstand its impact.

"This is a second-level mutant zombie, it should have run from the radiation zone in the south!"

Li Tao's face was solemn, the last time he fought with such a monster was half a year ago, the bullet was basically ineffective against it, this guy's head was like a steel helmet inside, extremely hard, and then he detonated the gas station before burying it in the fire.

Flame is indeed an effective weapon to kill zombies, which Gu Hongbo also knows, but he knows better that this tactic is not suitable for city defense warfare, because fire will not kill zombies immediately, but will easily set themselves on fire, and the fire and smoke will block the line of sight and affect the attack distance.

"Radiation zone? Doesn't radiation kill zombies? How can it be? How tenacious can the G virus be so tenacious? ”

Li Tao shook his head, "This is not how strong the G virus is, but because of the intensity of radiation, in the face of high-intensity radiation, no living thing can survive, but moderate radiation will induce genetic mutations, although most of these mutations are harmful, and occasionally there will be positive mutations, of course, I mean positive for zombies, the following thing is one of them!" ”

"One of them?"

Someone heard the overtone of this sentence, which meant that there was not only this one mutant zombie, but even more than this, and there were not only many terrible monsters hidden in the endless tide of corpses under the city.

There was a loud bang, and everyone's attention was drawn back to the defensive line.

At this time, the defense line was knocked out of a big depression under the impact of the huge body of the mutant zombie, and several corpse guards were shocked to the bottom, and they were eaten clean by the zombies that surged up in an instant.

Countless bullets hit the body of the mutant zombie, leaving only small holes one by one, the target of the head is too small to be aim, even if a few bullets are occasionally hit, they are bounced off instantly, leaving only a little white mark.

This image reminded Zhang Yuntian of the female corpse in the vault, and he wondered if the Disintegrator could also work on them.

The second line of defense was completely vulnerable in front of the mutant zombies, and in just a few clicks, the corpse wall was smashed to pieces, and the cars and corpses behind it could not stop its progress at all.

It jumped up and landed on the roof of a passenger car, its huge body slowly sinking into the car with the crushed roof, it struggled a few times, the bus shook violently, and then fell outward, knocking down a zombie that was sharing the gimbals.

The mutant zombie rolled backwards twice, then changed its route and rushed over again, slamming into the concrete city wall so hard that the people in the city trembled.

"RPG, hurry up, aim at its feet, blow it up, make it unable to move!"

Whoosh, boom~

Several high-explosive warheads exploded at the feet of the mutant zombies, and the flesh and blood immediately burst out, and a stream of green water flowed out of its stomach, and its mouth opened and closed, obviously not dead yet, but it had broken two legs, and it was difficult to launch an impact.

But this is not worth celebrating, its appearance disrupted Gu Hongbo's plan, originally thought that the second line of defense could last a few more minutes, but it was not as solid as the first line of defense, and it collapsed in less than ten minutes, and there were thirty minutes left before an hour, and the task suddenly became difficult.

The tide of corpses once again hit the city wall like a turbulent wave, the corpses gathered more and more under the city, accumulating layer by layer, getting higher and higher, and after more than ten minutes, the zombies could already climb the hill of corpses through guò and rush directly into the city wall, and the battle had entered the white-hot stage.

"All the direct troops charge!"

A hundred corpse guards armed with blast shields and hammers jumped up from the city wall and stepped on the corpse mountain, their shields connected to each other, forming a new line of defense, and as they advanced, they used their hammers to hit the zombies that rushed up.

They're not going to defend, they can't even stand the city walls, and how long can the blast shield last? Therefore, their main purpose is to expand outward, how far they can rush, and relying on this ** is tantamount to sending death to attack instead of defending, and to gain time.

According to this style of play, it is estimated that it will not be long before the corpse guard will be exhausted, but Gu Hongbo can't think about it so much, it will be a while if he can hold on for a while.

The direct troops expanded a distance of about three or five meters, and soon they couldn't hold on, there were more and more zombies, and they couldn't take a single step forward with their strength, and the two sides entered a temporary stalemate.

Soon, several emaciated corpse guards were pushed by the zombies, and then the entire defense line fell apart in an instant, and the corpses that burst like a bank rushed up again.

Gu Hongbo once again mobilized more than a hundred corpse guards and rushed out lightly, starting hand-to-hand combat by the city wall, at this time, there was no such thing as a line of defense, it was completely a pile of time, and he didn't have the time to see the time, if there was a miracle, it would be early, otherwise it would be too late.

Zhang Yuntian looked at the time, there were still seven minutes, but looking at the situation of the defensive line, it seemed that it was difficult to hold even a minute, was it going to end like this?

The rain was pouring down, but the sound of the rain could not hide the terrible ho-ho and the sound of desperate battle on the city walls.

Boom, a deafening thunder sounded, a huge silver lightning pierced the sky, straight to the ground, it seemed to have spirituality, did not shock the tall buildings on both sides, but straight to the corpses, the violent impact of the current, passed in the corpse tide, one by one, hundreds of zombies were inexplicably roasted into charcoal.

The thunder burst out, and dozens of lightning bolts slashed wildly towards the corpse tide one after another, stirring up silver fires among the zombies.

In fact, this is not the favor of God, but the result of the strong discharge of the G virus in the corpses, hundreds of thousands of zombies gathered together, which is simply a super conductor, directing the lightning in the sky.

The pressure on the city wall eased slightly, and Gu Hongbo hurriedly took the opportunity to transfer dozens of corpse guards to repopulate the lineup on the front line.
