    ?

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

    Huang Quan looked between the mountains of corpses, made an estimate, nodded and said:

    "The minimum attack distance of the Type 53 mortar is 85 meters, no problem"

    The firing speed of the Type 53 mortar is 25 rounds per minute. Of course, that is the speed of professional soldiers. Zhang Xiaoqiang's mortar team can't reach it, but with the practice of 2,000 mortars during the day, 20 rounds per minute  The speed of firing can still keep up. One cannon is 20 rounds per minute, and 12 cannons are 240 rounds per minute. For ten minutes, the frontal zombies hit by the tide of corpses were wiped out by the roar of 2,400 mortars.  The firing of 1,400 shells also made all 12 artillery groups tired.

    Zhang Xiaoqiang didn't know how many zombies were killed by those shells. He felt that the number of zombies on the first floor of the mountain of corpses had decreased significantly, and they would be destroyed as soon as they appeared.  Covered by a mountain of corpses on the second floor

    For a moment, Zhang Xiaoqiang's heart was suspended. He didn't know how much the corpse mountain could pile up in front of him. He only knew that the bullets in the camp seemed to be running out again.  As far as the walls, the two walls accommodated 8,000 people, which is almost the essence of the real gathering place.

    The further back, the more difficult it is. If the impact of the zombies is not as strong as before, I am afraid that the small river around them will have been filled. In the end, the zombies and humans are like two wrestling bulls.  It is not easy to climb up the corpse mountain of more than ten meters. Often, halfway through the climb, if one is not careful, countless people of the same kind will be knocked over and rolled to the bottom. If you are lucky, you can still climb up after rolling down.  Stepping on one's feet becomes a part of the mountain of corpses, and it is also uncomfortable to climb to the top. All the lights are adjusted to shine on the top of the mountain of corpses. Once the zombies emerge, several rifles shoot at the same time, and the kinetic energy of the bullets can make the zombies roll down.  .

    Zombies are uncomfortable, and humans are also suffering a lot. The continuous long-term high-intensity battle makes 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  If they continue to fight, I'm afraid their arms will be crippled.

    I don't know since when, the attack of the zombies was sporadic. Most of the human beings sat on the ground to rest, and only a fresh force of more than 2,000 people guarded the entire wall. Zhang Xiaoqiang looked hesitantly at the corpses that were getting higher and higher  Shan, he knew that the ammunition was really running out. After fighting all night, three million rounds of bullets turned into a mountain of corpses in front of him. Seeing the corpses that could only be looked up, Zhang Xiaoqiang suddenly felt a strange feeling  Thought, if you can kill so many zombies, it's worth it even if you die.

    Zombies and human beings are like two giants fighting. At the beginning, it was earth-shattering, then they were in a stalemate with each other, and now they are weak and weak. The attacks of zombies have completely lost their rhythm. Sometimes they appear in the same place one after another.  The pressure on the guards there is greatly increased. Sometimes there is no zombie in a place for tens of minutes, making the guards there want to doze off.

    Just as Zhang Xiaoqiang was observing the situation of the soldiers, Maoyan beside him suddenly fired a heavy machine gun that had been inactive for a long time. The huge gunshot brought Zhang Xiaoqiang back to his senses, and Huang Quan's roar came from his ears:

    "All heavy machine guns fire"

    At some point, the lonely zombies were replaced by tall d-type zombies. Behind countless d2-type zombies were countless dexterous s-type zombies. Z-type zombies finally released their final hole cards. At this time,  The sky is a little brighter

    When the sky was bright again, another hour and a half passed. This time, all the heavy machine gun bullets were fired, and all the heavy fire teams picked up their rifles, using their poor marksmanship to fight against the elite zombies.  Countless evolved zombies are like tigers descending the mountain, filling the river more than ten meters away. In the end, the soldiers on the fence risked being injured by grenades, and blasted the zombies in the river with waves of grenades.

    Nine thousand grenades took away more than multiple zombie corpses, and the river was constantly filled and exploded, but the grenades are limited, but the evolved zombies are infinite.

    In the end, the river was still filled with evolutionary zombies. Countless zombies crowded under the wall. When s2-type zombies appeared, casualties finally occurred. S2-type zombies could easily climb up the wall where evolutionary zombies could not climb. Fortunately, there were some  Two thousand fighters who have fought against s2 zombies know how to deal with them. As long as the zombies catch someone, no matter whether the person is willing or not, they will shoot their own people and s2 zombies to death together.

    There were more than 200 s2-type zombies that rushed up. Except for the 30-odd ones who were killed by thousands of rifles on the corpse mountain, all the others were easily shot at close range because of greed. One hundred and eighty-seven  One hundred and eighty-seven people were killed by s2-type zombies, but I can't tell.Whether it was a loss or a profit, it also made those soldiers who fought all night without casualties understand that standing on the fence does not mean safety.

    The s2-type zombies are followed by the d2-type zombies. Fortunately, the d2-type zombies are far less agile than the s2-type zombies.  Within an hour, the number of d2-type zombies that died in her hands reached more than 20.

    The second is Zhang Xiaoqiang's anti-aircraft machine gun. Other machine guns have no ammunition. His machine gun always has 800 ammunition and ten drums of ammunition in reserve. Before the s2 zombies appeared, Zhang Xiaoqiang was not willing to shoot because of d2.  The skin is thick, and three bullets must hit the same point to kill it in seconds. The d2 zombies are clumsy and move slowly, especially in the intertwined pile of corpses. There are twenty zombies on one drum, and the entire front of the wall  , All the d2 zombies that appeared within Zhang Xiaoqiang's range were killed by him. Calculated, the type 2 zombies that he killed with heavy machine guns these days can form an infantry battalion.

    There are also places that Zhang Xiaoqiang can't take care of, only a small part, these d2 type zombies were killed by an unexpected weapon, the 57mm recoilless gun, the armor penetration ability of the 57mm recoilless gun can reach  70 mm, within 20 meters, the data can be improved. The big d2 can't withstand the power of the armor-piercing bullets, and big holes are blown in the chest. Three armor-piercing bullets can solve a d2 type  Zombies moved Zhang Xiaoqiang. With this thing, a single soldier only needs a recoilless gun and 40 fire to deal with d2.

    When most people turned their attention to type 2 zombies, countless evolved zombies piled up under the wall. In the end, the first layer of the wall was broken. If there is no second layer of wall, no matter how many people die, the first layer of wall  I won't give up either. It's different now. When the zombies are about to be level with the first wall, all the personnel are ordered to retreat to the second wall. The second wall can't accommodate 8,000 people, so 3,000 people have been transferred.  After the wall, replace the cold weapon, and prepare to go all out at the last moment.  (Remember the site URL: www.hlnovel.com
