With a loud bang, the sky was filled with body parts and corpse water. The few people hiding not far away endured the rain of broken flesh and broken bones, as well as the most disgusting corpse water. They stood up. The smoke in front of them had yet to dissipate, and a small single-room cement building that had collapsed opened its mouth wide to the crowd.
Zhao Deyi led a few people to rush towards the entrance. Suddenly there was a concentrated gunfire coming from behind. Turning his head, he saw hundreds of people running towards Ai Qingshan and shooting below. His heart tightened. Did something really happen?
Ai Qingshan was not in the mood to remind Zhao Deyi. He continuously took out the bullets from the corpses beside him and sprayed them below. The soldiers beside him also used their fastest speed to shoot.
Below them was also a huge corpse mound. Surrounding the corpse mound were countless zombies. The zombies behind the first wall were all gathering here. It was obvious that their actions had alarmed the zombies inside. The Z-Types were also worried about their retreat and sent out troops to counterattack the wall.
At this moment, it was as if time had turned back to a few days ago when millions of zombies broke through the base's wall. Countless zombies formed a huge funnel. The center of the funnel was the slope of the corpse mound below the wall. But the slope here was wider and flatter than the previous one. The zombies behind the wall were also ten times more than the zombies outside the wall.
Thinking back to the time when tens of thousands of people couldn't stop them, how could only 300 people here?
This time, Zhao Deyi didn't even care about the electrical room and shouted for resistance. The soldiers who discovered that the anti-aircraft cannons were still in good condition also found a few people and got on the anti-aircraft cannons. They desperately turned the steering wheel and aimed at the corpse mound behind them. After the anti-aircraft cannons fired, the zombie tide on the corpse mound was slightly suppressed.
The zombie tide was only slightly suppressed. If it wasn't for the hundreds of experienced elite soldiers and Ai Qingshan's bullets, perhaps the zombies would have already rushed to the top of the wall and forced everyone to retreat.
Hundreds of rifles were firing at almost the same frequency. Every single shot was a single shot, and the interval between each shot was very short. Every single shot would cause the zombie horde to lose more than a hundred zombies. Ten seconds was a few hundred, and within a minute, nearly two thousand zombies had become a part of the zombie mound.
The soldiers brought by Zhao Deyi were different from the other defending forces. The other forces lacked the ability to fire live ammunition. Unless the zombies were within ten meters of them, they would not be able to hit the head of the zombies within three shots. If the distance was more than a hundred meters, only God knew if they could kill the zombies. Zhao Deyi's three mountain defending forces also lacked the ability to fire. But after twenty days of non-stop shooting, they had honed their skills. Every bullet could hit the head of the zombies within a hundred meters. Some of the better ones could hit the forehead within two hundred meters.
Based on this, each of Zhao Deyi's soldiers could fight against ten zombies. Others could kill two to three zombies with one magazine, while they could kill more than twenty zombies with one magazine. In addition, their ammunition consumption was less than one-tenth of the others. After all, when facing a real zombie tide, many people would pull the trigger to the end. No one could tell how many bullets were wasted because of this.
If that was the case, they would not be able to block the zombies. After all, the zombies were crowded together. Most of the people were aiming at the same zombie. This caused the efficiency to decrease. Many zombies were missed and continued to rush towards them. At this time, Ai Qingshan's role was very big.
Every time he shot, he could shoot hundreds of bullets at the same time. The hit rate of these bullets was average. Not every bullet would hit exactly one zombie. However, he had figured out how to use it. The zombies were all about the same height. As long as he spread the bullets towards the height of the zombies' head, it would be fine. Because of the need for density, he could not be too far away. Therefore, he would always put the zombies very close to him before shooting.
Even so, they could not stop the endless stream of zombies. The soldiers had to change their magazines. Ai Qingshan could not find many bullets around him. He needed to keep moving to find new bullets. In this way, they could not stop the zombies. The zombies were getting closer and closer to the top of the wall.
"Get out of there, quickly get out of there …"
Zhao Deyi was not in the mood to call for support. There was not enough time. The most important thing at the moment was to defend the wall. Once they were forced down, it would not be easy to recover the wall.
"Shi Yuan, throw the Shi Yuan, throw that thing out …"
Zhao Deyi finally thought of the weapon that could dissolve the corpses. Suddenly, hundreds of bottles filled with Shi Yuan were thrown out. Before they fell to the ground, they were smashed by bullets. The next moment, hundreds of thick green fog came out from the corpse mound. The zombie tide surged forward in the green fog.
Not long after, the zombies were covered by the fog. Only in the gaps could they be vaguely seen. The soldiers looked at Zhao Deyi. Shi Yuan blocked their line of sight. They did not know what to do next.
Should they wait for the zombies to rush up from the Shi Yuan?
"I'm a pig …"
Zhao Deyi cursed in his heart. He waved his hand and shouted:
"What are you waiting for?
Run … "
Without Shi Yuan blocking their line of sight, they could still hold on for a few minutes. But at this time, they could not even see the zombies clearly, let alone aim at the zombies' head. Zhao Deyi was out of ideas. He was also puzzled. Could it be that the zombies were not afraid of Shi Yuan when they were alive?
Three hundred people turned and ran in all directions. Some ran to the corpse mound, some ran to the end of the wall, and some prepared to enter the wall through the gap. The scene could only be described with one word, chaos.
Looking at these scattered soldiers, Zhao Deyi really wanted to let out a long roar to vent his frustrations. Once there was a change, these seemingly elite soldiers would be thrown into disarray. They were still far from being true elites.
"This way, jump down this way …"
Zhao Deyi pointed to the outer wall. There were many corpses under the wall. Although they were rotten, the height of the corpses was not small. Jumping down would give them enough buffer, as long as they did not die.
When Zhao Deyi rushed to the other side, there was a scream behind him, followed by a lot of people cheering. Most of the people stopped and turned around. The place where they had just attacked had been covered by the green mist from the corrosive source. Until now, not a single zombie had appeared. The people cheering could see the inner side of the wall. It seemed like they had discovered something?
"Don't run, don't run, the zombies are all dead …"
Hearing the cheering of the soldiers, Zhao Deyi still could not believe it. He rushed over and saw that the entire corpse mound was covered by the green fog. As the fog flowed, the corpse mound became smaller and smaller. It slowly shrank to the ground, like a deflated balloon.
"Look, look, the zombies behind are also covered. The zombies are in chaos …"
There were a few people pointing to the edge of the corpse mound. The previously crowded zombies were all covered by the green fog. As the density of the zombies continued to spread, although the color was not as deep as that of the corpse mound, it was enough to cover tens of thousands of zombies.
"Deputy division commander, deputy division commander …"
Zhao Deyi was beaming with joy as he watched. The warrior next to him tugged at his sleeve with all his might, forcing him to turn his attention to the warrior. The young warrior's lips were trembling, and his other hand was pointing at the wall as he trembled.
"What the hell … spread out, spread out …"
Zhao Deyi saw the green fog spreading on top of the wall. There was a lot of corpse water on top of the wall. This corpse water was nourishment for the fog. The fog covered the corpses one by one. It looked like it was about to spread to the entire wall. If it was just like that, then it would be fine. When the debris piled up on top of the wall quickly melted in the green fog, he understood that this thing was not only useful for zombies, but for almost everything.
The soldiers all dodged the corrosive source. Corpses and corpse water were everywhere on top of the wall. It seemed like they had nowhere to hide. Most of them looked behind the wall. Zhao Deyi was the first to come to his senses and shouted, "Go down, go inside the wall …"
More than three hundred people rushed into the inner layer of the wall. They stepped on countless corpses and ran along the long and narrow passage. When they reached here, they still did not feel relieved. They turned on their tactical flashlights and continued to run inside like a swarm of bees. Zhao Deyi was squeezed in the center. He let people push him as they ran. Not long after, he found that the ground under his feet was flat. There were no more corpses. Just when he was about to order them to stop, he heard a scream coming from the front. The next moment, the sound of many heavy objects falling to the ground could be heard.
The continuous screams made the people behind stop. The soldiers at the back couldn't stop in time and bumped into the people in front. People bumped into people, people pushed people. The people at the front were knocked out by the people at the back. Then there were a few more screams. For a moment, everyone in the passage panicked. They shone their flashlights everywhere. Loud and low voices filled the entire passage. Not to mention the shouts of many people, just the echoes of the passage made people's eardrums numb.
"Bang … Bang … Bang …"
There was a flash of light, and the crisp sound of a pistol suppressed most of the shouts. In an instant, all the voices disappeared. Only Zhao Zhigang shouted, "Silence …"
As soon as his voice fell, there was a burst of crisp metal collision and groaning in front of them. Then, someone shouted:
"It's okay, it's just a fall. The ground is full of shell casings. Everyone, be careful not to fall …"
The stagnant flow of people moved again. When they walked to the place where the accident happened, they found that the ground was full of thick shell casings. The shell casings were spread on the ground like a carpet. If they didn't pay attention and stepped on them, they would definitely fall. In the corner, there were a few people who just fell. They were all holding their waists and buttocks.
After a false alarm, everyone moved forward again. However, they found that all the iron doors were locked. The people outside really couldn't pry open these iron doors. This place turned out to be an internal defense facility to prevent the enemy from attacking from the outside. The thick iron doors could only be opened from the inside …
