"We need more heavy machine guns! Heavy machine guns! Liu Gong, what kind of goods are your machine guns, and they will be finished in less than half an hour? Can't even find the fault anywhere? Chen Deyuan's face was flushed and he yelled at the cadres of the technical department.

Li Xiaoshi beside him and the others were all busy letting the major stop the fire, and the members of the technical department led by Liu Wennan all lowered their heads and were silent. It's just that these technicians are also red-faced, obviously with fire in their hearts.

Leng Yang, who was sitting in the middle, couldn't help but scratch his scalp, he was also very helpless. Both sides tried their best, and no one can blame them, but this thing is really a nest.

The battle with the zombie group has been going on for two days, and the large number of tongue zombies has made people's suppression effect relatively poor, and the corpse mound of the zombie group has been pushed up to more than three meters. People have tried all kinds of ways to block the zombie herd, but the speed at which these zombies spread up the corpse mound is still much faster than people imagined.

In this case, the heavy machine gun in the team was the only bright spot. Using this metal stream launcher at close range, you can smash large hordes of zombies to pieces. After the improvement of the people, the heavy machine gun can be fired at an angle in the platform in the room, which is a very good weapon.

But what made Chen Deyuan and them angry was all the heavy machine guns, and if they didn't fire 2,000 rounds, something would go wrong. This ammunition simply does not allow people to take advantage of the heavy machine gun. On the contrary, in the first few accidents, the combat troops also sacrificed many people for this.

But there is no way for the technical department. Originally, due to the influence of the fog, these weapons were equivalent to being abandoned. Many parts are handmade by Liu Wennan himself before they can be used. In this case, the properties of the material are not up to the mark, and it is easy to have problems.

But what can the technical department do? Being able to make these machine guns shoot thousands of rounds is already Liu Wennan's ability, and if you change some technicians who are not familiar with the military industry, you can't shoot a single bullet.

"It's all quiet! I know Chen Deyuan, you have killed many comrades-in-arms because of the battle, and your heart is on fire. But the technical department has done its best, you must know that these guns are actually scrap guns! It's good that they've been able to fix some. ”

With the roar of the cold sun, the entire conference room fell silent. In the middle of the ring, Chen Deyuan gave a military salute to Liu Wennan and them very formally, "I'm sorry, Liu Gong, and everyone." I was just excited. ”

Yan Shibin waved his hand, went to the battlefield and watched the sacrifice of his comrades, everyone was angry, they could understand it. It's just that the technical department really has no other way, unless it gets more accessories now, or asks Liu Wennan and them to find the material laboratory. It's just that none of that is possible.

"The zombies attack, you have to use heavy machine guns?" Leng Yang had some doubts, he didn't seem to be in a hurry about this thing before, and now the corpse mound can't threaten the shooting room.

Without saying a word, Feng Ye took a few pictures and projected them onto the wall of the conference room. The projection that appeared on the wall was a few zombies. But unlike the other zombies, these zombies act like geckos, and they are climbing towards the walls and hillsides.

Feng Ye pointed at the projection of the zombie with a laser pointer, "This kind of zombie appeared this morning and can climb directly on the almost vertical city wall. It doesn't move fast, but it won't fall without the influence of an external force. It takes about five minutes to climb to a height of almost ten meters above the ground. ”

Looking at the earth-colored city walls, these crawling zombies dotted with stars, like flies on a cake, make people feel disgusting.

There are not many of them, but they are a lot of harassment to people. There are two types of zombies that can threaten the warriors, the zombies with tongues and the crawling zombies, and the frequency of the fighters in the shooting room is naturally greatly reduced, which in turn makes the corpse mound push up faster and makes people more nervous.

"This kind of zombie has appeared before, but we didn't expect the zombie army in Jiangcheng to react so quickly this time." With Yu Linrong's reminder, people gradually recalled that it was also a group of zombies in Jiangcheng at the beginning, but almost half of the fierce battle before this kind of zombie appeared.

Duanmufeng's medical laboratory also has some research on zombies, and the difference between various mutated zombies is because they have a different form of enzyme in their limbs.

This enzyme is most stable on the three most common mutant zombies: Assassin Zombies, Iron Zombies, and Jumping Zombies. The other mutant zombies have more or less unstable activation states.

With Duanmufeng's judgment, coupled with previous battle examples, people are naturally easy to associate with it. Except for those three zombies, all the other mutated zombies were spawned by red monsters.

And through the study of the corpse of the red monster, although Duanmu Feng doesn't know much, he at least understands that this animal also needs energy to survive. So in other words, it is necessary to consume energy to give birth to these evolutionary zombies, and this kind of thing will not be done by red monsters without being fine.

However, now that it is only the fourth day of the battle, there have already been zombies specially developed for the city wall. And as the battle progresses, if people can't come up with effective ways to travel, naturally there will be more and more zombies.

Leng Yang rubbed the stubble on his chin vigorously, the zombie army in Jiangcheng, the proportion of mutant zombies was far more than one-third, and the collection of these huge number of mutant zombies gave people a lot of threats.

"Let's go, I'll go to the front line. Yuning, you mobilize the manpower in the base and continue to repair the city wall behind. Leng Yang stood up and said loudly. As the captain of the team, he doesn't have to be afraid of going to the battlefield, because he has always been the first person on the battlefield before.

"Da-da-da, da-da-da!" The rifle in Jiang Jinfu's hand continued to roar, and under the city wall below him, the two climbing gecko zombies were shot off their heads without any suspense, and fell on the gradually rising corpse mound, becoming part of the steps.

Just as the lieutenant colonel was changing the magazine, a shout came from beside him, "Be careful! Before Jiang Jinfu could react, he was knocked down by a huge force, and even rolled out several times with a gun.

Leng Yang, who was walking on the city wall, could clearly see that at the top of the city wall, a row of soldiers dressed in camouflage uniforms and wearing fiery red helmets stood proudly with wide explosion-proof shields in their hands. Behind them, a warrior wearing a helmet, under the cover of a shield, fired at the crawling gecko zombies on the wall beneath their feet.

These warriors with human shields were not absolutely safe, and in the short time that Leng Yang walked up to the city wall, he heard several muffled sounds. It was the sound of throwing zombies against the shield, and not every zombie would be blocked by people.

Jiang Jinfu's head slammed above the ground, and when he shook his head and was about to stand up, beside him, a large handful of black blood splashed the former lieutenant colonel's body. There was also an iron-clad zombie whose heavy body fell heavily on the city wall.

Li Xiang wiped his short spear on his thigh, and stood back behind Leng Yang, from beginning to end, the bodyguard did not look squarely at the iron-armored zombie that was thrown onto the city wall and knocked down Jiang Jinfu and his comrades.

The muffled sound on the city wall continued, and Leng Yang could clearly see that many soldiers with bulletproof shields held their shields on the ground from time to time in order to save their physical strength. This defense can't be too long-lasting.

"Use the shield as cover, and when needed, extend the shield forward, leaving a gap underneath to shoot. This is a good idea, but this method will gradually lose its effectiveness as the mound grows taller. "After observing for a while, the people in the command determined the advantages and disadvantages of such a battle.

Now the corpse mound under the city wall is not high enough, and only the giant bear zombies and some ironclad zombies in a better position can throw the zombies up. As time goes by, there will be more and more of these throwing zombies, and the top of the city wall was originally designed to be narrower, just for this consideration.

Leng Yang bit his lip, he had to come up with a way not to completely eliminate the gecko zombies, but at least to weaken the threat of this zombies. Otherwise, the red monster will definitely create this kind of zombie in large numbers, and then people will be in trouble.

"Let them go up the walls? No, the biggest threat to these guys is the shooting room. And it's not easy to have too many of them, and they can directly form corpse mounds. ”

"Direct point shot from the anti-slope? If only we had a position hanging in the air. "In fact, the gecko zombies are not fast, and the target is very obvious. But alas, only the attacker can see clearly.

"Fortify the shield, or build the wall that comes out of it?" The city wall behind could have been guarded against this, but this one was clearly too late.

Leng Yang kept walking around on the city wall, and this matter had to find a way to solve it. Now he finally understands what it says in some military books he has read before, and it is better to make a decision, even if it is a bad decision, than to hesitate.

Maybe in ordinary life, there is a better choice to hesitate, but on the battlefield, it is really sitting still.

Unconsciously, Leng Yang raised his head and looked around, looking at the dense zombies on the highway in the distance, and then at the comrades who were busy carrying various supplies behind the road. In fact, they are really all like, they are the same kind, but they are fighting for life and death across the wall.

Suddenly, Leng Yang noticed the hot air balloon rising just behind the road, the huge black shadow projected on the ground. He held his head high and looked at the sky.

In this blue sky, white clouds, and clear skies, people not only have hot air balloons high above, but also have two crane booms that can move freely dozens of meters high. Correspondingly, the zombie army has nothing.

"Hey, hey, you forced me. We don't have that many new troops, but I still know a little bit about three-dimensional defense. A smile appeared on Leng Yang's face, and the otaku who thought of the solution was very complacent.
