(); More time:――

All the changes in the zombies also fell into the eyes of Huang Quan and Zhang Xiaoqiang, and they guessed the reason at that time, the area in the rear was too narrow, with mountains on one side and lake shores on the other, the zombies could not keep up with the rhythm of the attack, they were waiting for the zombies behind to gather, and they were using all their forces to make a general attack.

"Let's shoot......"

Zhang Xiaoqiang said to Huang Quan that they couldn't sit and wait, they had to disrupt the rhythm of the zombies as much as possible and control all the advantages in their own hands.

Huang Quan gave the order, and Zhang Xiaoqiang walked to the . On the side of the millimeter anti-aircraft machine gun, Yang Keer on the left, and cat's eye on the right, there are three logistics personnel behind each machine gun ready to replace the barrel and ammunition at any time, and put the butt on his shoulder, Zhang Xiaoqiang took a deep breath of air with a strong smell of gunpowder smoke and rot, and at the same time as the five cannons in the rear roared, the heavy machine gun in Zhang Xiaoqiang's hand fired, and the first light chain flew out, and Yang Keer, who had already been unable to bear it, followed by the cat's eye, and then the heavy firepower of the entire front fired at the same time.

"Boom...... Boom ......"

Five huge flames exploded in front of them in a row, and the place where the explosion sounded was at least a thousand meters away from the river, and the people on the wall were not careful, and when they saw the five huge flames, they were re-covered in darkness when they saw the five huge fires flashing, but the huge fire ball impressed them, and when they thought that it was their cannon, the coldness in their hearts that was startled by the zombies in the distance turned into fire again.

The zombies 100 meters away were shattered by hundreds of tongues of fire, and the Z-type zombies were mobilizing their troops, and before it could react, the zombies at a distance of 100 meters to 150 meters all flew into the sky, among them, all the places that were taken care of by the 4.mm twin anti-aircraft machine guns were all huge pits.

Subsequently, the mortar on the wall also began to fire, and thirty consecutive rounds of rapid fire exploded one after another in the 300 meters to 500 meters of the zombie sea, more zombies flew into the sky, and the open space was re-revealed after the explosion of the fire flashed, and the continuous blows made the zombies consume at least tens of thousands of zombies in a short period of time.

More than 100 heavy firepower formed a scattered firepower network 100 meters away, almost half of the zombies were blocked by the firepower network, torn to pieces, and some zombies rushed through the firepower network and climbed onto the corpse wall, at this time, the rifle fire of the entire front was resurrected, and in the gunfire, the zombies fell on the pile of corpses and became part of the corpse mountain.

At this time, the two-layer fire interception is better than the previous single-layer interception, just now all kinds of bullets flew into a blur of everyone's eyes, and now, under the light, the zombies climbed the corpse mountain with difficulty to become the target of the rifleman's shooting, the accuracy rate rose rapidly, and the ammunition consumption was declining.

The vast majority of zombies were shot through two layers of fire nets, and some of the fish that slipped through the net were also shot by soldiers who had leisure in the open space thirty meters to the river, and the scattered corpses extended from the corpse mountain to the river, in the river by the river, countless black zombies were entangled together, with the undulations of the river, almost extended to the middle of the river, unconsciously, the zombies filled half of the river with corpses.

Suddenly, countless black dots flew out of the wall and smashed in the middle of the corpses in the river, countless waves exploded in the river, countless grenades exploded the zombies in the river, and between the rolling waves, countless black corpses floated out of the river bank in a swirling way, flowed downward, and floated all the way to the big lake.

In the second half of the night, the gunfire on the wall has not stopped, and the hearts of the survivors in the gathering place have not been put down, the zombies have not stopped impacting this time, wave after wave generally surging towards the gathering place, a hundred meters away has been piled up into a taller corpse mound, the front and rear two corpse mounds have accumulated at the same time, almost level with the second layer of the wall, the zombies on the meter-high corpse mound have been shot from time to time and rolled down the corpse mound, and countless corpses have been superimposed on the distance from thirty meters to the river, some of which are already three or four meters high, I don't know how many zombies were killed.

Zhang Xiaoqiang was shooting, and keenly felt that the impact of the zombies was decreasing, and at this time, his heavy machine gun had replaced no less than four or five barrels, and the brass bullet casings under his feet had buried his calves.

Released the trigger, Zhang Xiaoqiang closed his eyes, and drove the dizziness in his brain, and then he himself was frightened by two huge corpse mountains, the two corpse mountains are also six meters short, and the height is level with the wall, and the zombies at the foot of the corpse mountain are also several meters high layer upon layer, and many have fallen into the middle of the river, the flow of the river is a little slow, countless zombies are floating in the middle of the river, turning around and floating downstream, fortunately the river is flowing, fortunately, the zombies that fell into the river are only a small part, otherwise the river may have been filled with zombies.

During the day, each of the six corpse mountains with breaches as high as ten meters has at least 5,000 zombies, here, how many zombies are there in the corpse mountain that stretches for several kilometers, Zhang Xiaoqiang no longer dares to think, at least, there are 200,000, plus the corpse mountain behind, I believe that the strength of the zombies is about to bottom out.

"Brother Cockroach, we're running out of bullets for our heavy machine guns......"

Zhang Huai'an was sweating profusely, and ran to Zhang Xiaoqiang's side with an anxious face and said, as the logistics director, his heart is hanging at the moment, and this is only a small half of the night, 300,000 rounds. Millimeter armor-piercing incendiary shells are about to bottom out, and there are no ones in the camp, only there are still 400,000 rounds in stock on the island, but now there is no time to transfer them, and the ships are sent over to steal ammunition from the arsenal, because there are not many rifle bullets, and mortar shells are even more scarce, and similarly, there are a lot of millimeter mortar shells, only . There are many millimeter high-explosive bombs, more than 2,000.

The battle on the front line is urgent, and the dead zombies are piled up into a mountain, but there are still many living zombies, and now is a critical moment, the zombies are competing with them in endurance, whoever can hold out until the next moment will be able to achieve victory, the only difference is that the zombies can come a second time if they fail, they fail, and can only retreat to the island in the middle of the lake through the hidden bamboo raft.

Hearing Zhang Huai'an's report, Zhang Xiaoqiang's eyebrows were twisted, and he looked at the zombies that kept rushing up the mountain of corpses in the distance and were broken and beaten, and said, "How many ...... are left?"

"About 30,000 rounds, only 300 rounds per machine gun, perhaps, in another ten minutes, the whole line of heavy machine guns will cease firing...... But there are quite a few bullets of 4. caliber, and there are at least two thousand rounds each......"

When Zhang Xiaoqiang heard this, he immediately shouted at Huang Quan in the distance:

"All. Caliber heavy machine guns ceasefire ...... All. Caliber heavy machine gun ceasefire ......"

The fire of the heavy machine guns stopped one after another, and only five 4.mm twin units fired intermittently, and on the corpse mountain a hundred meters away, the pressure of the zombies dropped sharply, and countless zombies crawled down the corpse pile with difficulty.

The blocking line 100 meters away was in vain, and there were suddenly more zombies on the corpse mountain 30 meters away, and 6,000 rifles were dealing with it at the same time, which was a little difficult, and when it came to those zombies, Zhang Xiaoqiang's heart was anxious, and he turned to the place where he was hoarding ammunition, but he saw countless wooden boxes open, and there was nothing in them, but the place behind the wall where the mortar shells were stored was piled up into a mountain.

"Huang Quan, can the mortar hit the middle of the two corpse mountains?"
