Just as Gu Hongbo gradually mastered the rhythm of the battle, he had a sudden change of mutant corpses. A mutant zombie the size of a car had piled up on his body, like a giant beast with a rolling head, still of normal size, and a bunch of sarcoma bulges on his back, looking very disgusting.

It was moving very fast, and it was on all sides, half crawling and half running, rushing towards the front line, stepping on the zombies blocking the way, and crushing their bones with its huge bodies, making a creaking sound.

"This...what monster is this?"

The officials in the mail tower all turned green. The endless tide of corpses was already a nightmare. Now such a monster appeared again. I really don’t know if the city wall can withstand its impact.

"This is a level 2 mutant zombie, and it should have come from the radiation area 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 on it. This guy's head was like a steel helmet inside, which was extremely hard. Later, he detonated the gas station and buried it in the fire.

Flame is indeed an effective weapon to kill zombies, Gu Hongbo also knows this, but he knows more that this tactic is not suitable for use in city defense battles, because fire will not kill zombies immediately, but will easily cause fire to burn, and the fire and thick smoke will block your sight and affect the attack distance.

"Radiation zone? Can radiation kill zombies? How is it possible? The G virus is so tenacious?"

Li Tao shook his head, "This is not how powerful the G virus is, but because of the intensity of the radiation. No organism can survive in the face of high-intensity radiation, but moderate radiation will induce gene mutations. Although most of these mutations are harmful, there will be positive mutations occasionally. Of course, what I mean by the positive is that for zombies, the following thing is one of them!"

“One of them?”

Someone heard the implicit meaning of this sentence, which means that there are not only one mutant zombies, or even one. Not only are there many terrible monsters hidden in the endless tide of corpses under the city.

A loud bang attracted everyone's eyes to the defense line again.

At this time, the defense line was hit by the huge body of the mutant zombie, and several corpse guards were shaken down and were eaten by the zombies that rushed up.

Countless bullets hit the bodies of the mutant zombies, leaving only small holes. The target of the head is too small, which is not conducive to aiming. Even if a few bullets occasionally hit, they will be bounced away instantly, leaving only a little white mark.

This scene reminded Zhang Yuntian of the female corpse in the vault, and he didn't know if the disintegrator could work for them.

The second line of defense was vulnerable to the mutant zombies. Within a few strokes, the corpse wall was smashed to pieces, and the cars and corpses behind could not stop it from moving forward at all.

It jumped up and was landing on the roof of a bus. Its huge body slowly sank into the car with the crushing roof. It struggled a few times. The bus shook violently, then fell outward, knocking down a zombie that was sharing the corpse guards.

The mutant zombie rolled back twice, then changed a route, rushed over again, and hit the cement city wall hard, causing the people on the city to tremble.

"RPG, hurry up, aim at its feet and blow it up so that it cannot move!"

Whoosh, boom~

Several high-explosive warheads exploded under the feet of the mutant zombie, and blood and flesh immediately splashed, and a thick green water flowed out of its belly. Its mouth opened and closed, obviously not dead yet, but it had broken its legs and it was difficult to start an impact.

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

The tide of corpses once again hit the city wall like surging waves. The corpses gathered more and more under the city, and they accumulated layer by layer, getting higher and higher. After more than ten minutes, the zombies could rush directly into the city wall by climbing up the hills made of corpses. The battle had entered a white-hot stage.

"The entire direct troops charged!"

One hundred corpse guards holding explosion-proof shields and iron hammers jumped up from the city wall and stepped on the corpse mountain. The shields connected to each other to form a new line of defense. While moving forward, they used the hammer in their hands to hit the zombies rushing up.

Theirs are not about defending, they can't even stand the city walls, how long can the explosion-proof shield last? So their main purpose is to expand outward, and to rush as far as they can. Relying on this ** is tantamount to killing the attack instead of defending, and gaining time.

According to this kind of fighting style, it is estimated that the corpse guards will be exhausted in no time, but Gu Hongbo can't think so much, it's time to hold on for a while.

The direct troops expanded outward by about three or five meters, and soon they could not hold on. There were more and more zombies, and with their strength, they could not move forward any further. The two sides entered a brief stalemate.

Soon several thin corpse guards were pushed by the zombies, and then the entire defense line collapsed instantly, and the group of corpses like broken dams rushed up again.

Gu Hongbo once again mobilized more than 100 corpse guards and rushed out lightly and started hand-to-hand combat by the city wall. At this time, there was no such thing as not being a defense line. He was just using the heads to accumulate time, and he had no time to see the time. If a miracle happened, just as soon as possible, otherwise everything would be too late.

Zhang Yuntian looked at the time, and there were still seven minutes left. However, looking at the situation of the defense line, it seemed that it was difficult to defend even a minute. Is it going to end like this?

The heavy rain poured down, but the rustling sound of rain could not block the terrifying hoho sound and the sound of fighting to the death on the city wall.

Boom, a deafening thunder sounded, and a huge silver lightning broke through the sky and slashed straight towards the ground. It seemed as if it was spiritual. It did not shock the tall buildings on both sides, but slashed straight towards the corpse group. The violent impact of the electric current was transmitted in the tide of corpses, one by one, and hundreds of zombies were inexplicably roasted into coke.

Thunder broke out, and dozens of lightning flashed wildly at the corpse tide, stirring up silver flames among the zombies.

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

The pressure on the city wall was slightly relieved, and Gu Hongbo hurriedly took the opportunity to draw dozens of corpse guards to re-stack the front line.
