(); More time:――

Zhang Xiaoqiang couldn't think about it, so he thought of using scattered mortars to concentrate on bombing in the middle of the corpse mountain, and there should be countless zombies piling up below.

Huang Quan looked at the mountain of corpses, estimated, nodded and said:

"The small attack distance of the mortar is meters, no problem......"

The firing speed of the mortar is per minute, of course, that is the speed of professional soldiers, Zhang Xiaoqiang's mortar team can not reach it, but with the practice of 2,000 mortars during the day, the speed of firing per minute can still keep up, a cannon is fired per minute, the door gun is 4 rounds per minute, a full ten minutes, the frontal zombies of the corpse tide impact were wiped out in the roar of 2,400 mortars, and the firing of 2,400 shells also made all the artillery crews tired.

Zhang Xiaoqiang didn't know how many zombies those shells had killed and injured, he felt that the zombies in the first layer of the corpse mountain had decreased significantly, and they were often knocked out as soon as they appeared, and at the same time, the corpse mountain on the first layer had completely exceeded the height of the wall, covering the second layer of the corpse mountain......

For a while, Zhang Xiaoqiang's heart hung in the air, he didn't know how much high energy the corpse mountain in front of him was, he only knew that the bullets in the camp seemed to be about to run out of danger again, this time, the two thousand meters of soldiers who had withdrawn to rest during the day went up to the wall again, and the two walls contained thousands of people, which was almost the essence of a real gathering place.

The more to the back, the more difficult it feels, if it weren't for the impact of the zombies is not as good as before, I'm afraid that the small river around them would have been filled up long ago, and after that, the zombies and humans want to wrestle with the two brute bulls, each of them has reached the extreme, and it is not easy for zombies to climb more than ten meters of corpse mountain, often climb halfway, one will accidentally smash over countless similar people and roll to the bottom, if you are lucky, you can climb up, and a lot of luck can only be trampled on by the same kind of feet to become a part of the corpse mountain, and it is not comfortable to climb to the top, all the lights are adjusted, Shine on the upper layer of the corpse mountain, once the zombie shows its head, several rifles shoot at the same time, and the kinetic energy of the bullet can make the zombie roll down.

Zombies are not comfortable, and humans are also a lot of people, continuous long-term and high-intensity battles make everyone's shoulders swollen and high, every time they shoot, their shoulders are numb and sore, they don't dare to think about it, they only know that if they continue to fight, I'm afraid their shoulders will be wasted.

I don't know since when, the zombie attack is scattered, most of the human side are sitting on the ground to rest, only more than 2,000 people of the new force to guard the entire wall, Zhang Xiaoqiang hesitated to look at the higher and higher corpse mountain, he knows, the ammunition is really running out, a whole night of fighting, three million bullets have become a mountain of corpses in front of him, with the corpses that need to look up to look up, Zhang Xiaoqiang suddenly had a strange thought, can kill so many zombies, even if it is worth it to die.

Zombies and humans are like two giants fighting, the beginning of the earth-shattering, to the stalemate between each other, to the current weakness, the zombie's attack has completely lost its rhythm, sometimes and three appear in the same place, so that the pressure on the guards there is greatly increased, sometimes a place does not see a zombie for dozens of minutes, so that the guards there want to doze off.

Just when Zhang Xiaoqiang was observing the situation of the soldiers, the cat's eye next to him suddenly activated the heavy machine gun that had been stopped for a long time, and the huge gunfire made Zhang Xiaoqiang come back to his senses, and Huang Quan's roar came from his ears:

"All heavy machine guns ...... fire"

I don't know when, the lonely zombies were replaced by tall D-type zombies, behind countless D-type zombies are countless dexterous zombies, Z-type zombies finally sent out the hole cards, at this time, the sky showed a little brightness......

When the sky was bright again, another hour and a half passed, this time, all the heavy machine gun bullets were fired, all the heavy fire teams all picked up their rifles, and used their poor marksmanship to fight the elite among the zombies, countless evolved zombies were like tigers descending from the mountain, filling the river of more than ten meters, and after arriving, the soldiers on the wall risked being injured by the grenade, and used a ** grenade to blow up the zombies in the river.

Nine thousand grenades have taken away more than multiple zombie corpses, and rivers are constantly filled and blown up, but grenades are limited, and evolutionary zombies are infinite.

The end of the river is still filled by the evolution of the zombies, countless zombies crowded under the wall, when the type of zombies appeared, the casualties finally occurred, the evolution of the zombies can not get up the wall, but the type of zombies can easily come up, fortunately there are two thousand soldiers who have fought with zombies know how to deal with it, as long as the zombies catch someone, whether that person wants to or not, a random shot will shoot their own people and zombies together.

There are more than 200 zombies that pounced up, except for more than 30 who were killed by thousands of rifles on the corpse mountain, the others were all easily shot at close range because of greed, and the 17 zombies exchanged 17 lives, and it was not clear whether they lost or earned, and at the same time, they also made those soldiers who fought all night and had no casualties understand that standing on the wall does not mean safety.

Behind the type zombie is the D-type zombie, fortunately, the D-type zombie is far less agile than the type zombie, Shangguan Qiaoyun has become a big highlight, a. The millimeter bile duct gun shot all the D-type zombies that approached, and within half an hour, more than 20 D-type zombies died in her hands.

The second is Zhang Xiaoqiang's anti-aircraft machine gun, other machine guns have no ammunition, his machine gun always has 100 ammunition, ten drums in reserve, the previous type of zombie appeared, Zhang Xiaoqiang was not willing to shoot for D preparation, D has thick skin, must be hit by three bullets at the same point to kill it in seconds, and D type zombies are clumsy and move slowly, especially in the intertwined corpse pile, a drum of twenty zombies, on the entire front of the wall, all the D type zombies that appeared within Zhang Xiaoqiang's range were killed by him, count, The zombies he kills with heavy machine guns these days can form an infantry battalion.

There are also places that Zhang Xiaoqiang can't take care of, just a small part, these D-type zombies were killed by an unexpected weapon, 57 mm recoilless cannon, 57 mm recoilless cannon armor-piercing ability can reach millimeters, within 20 meters, the data can be improved, D's big guy can't withstand the power of armor-piercing bullets, and blasts out big holes in his chest, three armor-piercing shells can solve a D-type zombie, so that Zhang Xiaoqiang is intended, with this thing, a single soldier only needs a recoilless cannon and 4 fires to deal with D.

When most people set their sights on the zombies, countless evolutionary zombies were stacked under the wall, and finally, the first layer of the wall was broken, if there was no second layer of the wall, even if there were more people who died, the first layer of the wall would not give up, now it was different, when the zombies were about to be level with the first layer of the wall, all the personnel were ordered to withdraw the second layer of the wall, the second layer of the wall could not accommodate more than a thousand people, and after transferring three thousand people to the wall, they replaced the cold weapons, ready to fight desperately in the future.
