This kind of shadow was continuous. Countless black dots would explode into the sky from the grenades, forming a dark cloud. More dark clouds would form from the explosions below. After the grenade shells exploded the zombies, they would form dense shrapnel, like a circular fan that swept away the surrounding zombies. The dense shrapnel was comparable to a metal storm, causing all the black zombies to fall to the ground. Even if there were zombies that were in groups of three to five that managed to avoid the explosions, they would still be shot by the rifle bullets.
At this time, the majority of the light weapons had become secondary. Even the Type-89 HMG was not as powerful as it was before. All the limelight had been stolen by the machine guns.
The cannons in the base were all new equipment that was prepared to be used for fixed firepower clearing. This type of weapon had an excellent recoil system. At the same time of firing, all the recoil was completely consumed. When the hydraulic refrigeration device restored the cannon barrel, it would return to the previous firing point without the slightest deviation.
With this system, the machine guns did not need to worry about accuracy. The long ammunition chain also provided continuous benefits. The bullets would automatically be squeezed into the magazine. Following the firing of the machine guns, thick bullet casings would be thrown out. The yellowish orange bullet casings still had a layer of oil on them as they rolled on the ground. At this time, someone wearing asbestos gloves would pick up the casings. The base not only had the ability to regenerate bullets, they could also regenerate small caliber artillery shells.
The new 23mm machine guns were the nemesis of the normal zombies. If it was not for the weight and size of the machine guns, it might have become the most effective method for attacking troops. At the very least, a machine gun was comparable to five 12.7mm HMG.
Although there were only six cannons on both sides, just these six cannons were already stronger than the firepower of two infantry companies. Under the firepower of the cannons and heavy machine guns, the front of the zombie horde was like burnt ashes, continuously scattering, and finally became pieces of meat paste mixed with the corpses.
At this time, there was still a steady stream of zombies rushing down from the hilltop. Even more zombies rolled down the hilltop, piling up a huge mountain of corpses. The mountain of corpses was like a pile of wriggling worms. Countless zombies were wriggling, trying their best to break free and join the corpse tide on the road. The original shadow of the road could no longer be seen, it was completely black. It was impossible to know where the road was before, and it was also unknown where it was at the foot of the zombie tide.
Because of the continuous firing of the machine guns, the soldiers' shoulders became bruised from the continuous firing. Finally, the first zombie rushed into the valley. When the first zombie was shot, more and more zombies rushed into the valley. The valley was the psychological line of defense for the two sides of the mountain. Because of the shooting angle, it was impossible for them to kill all the zombies that entered the valley. Thus, when more zombies entered the valley, the firepower of the mountain did not increase, but instead continued to weaken, as if they had lost confidence because of the zombies.
At this time, the reinforcements came up. The two companies of reinforcements doubled the firepower of the mountain top, and the number of zombies that rushed into the valley was reduced to zero. However, there were too many zombies at the bottom of the mountain. Countless zombies were densely packed together, and their black heads were swaying. Together with the heads of the surrounding zombies, they formed a dizzying sea of heads. Every time they aimed, it was easy to be misled by the other heads in the scope.
The entire hillside was filled with zombies. Previously, tens of thousands of zombies had already covered the ground from the foot of the hill to the top of the hill. However, some zombies were rolling, some were walking, and some were jumping. The scene in front of them made all the soldiers break out in cold sweat. Cold sweat rushed from their spines to the top of their heads, and then into their hearts, making them feel cold. Even the rifles felt as heavy as a thousand catties, and they always wanted to throw them away and run away, but most of them felt like they couldn't concentrate on fighting.
"Hold on, hold on, we can't run, if we run, we will die. The mutated humans can't come up, we are very safe …"
From the loudspeaker, a slightly trembling roar resounded through the two hilltops. The battalion commander who was in charge of the hilltop bit the bullet and encouraged the soldiers below. This was the first time the soldiers had faced such a magnificent zombie tide, and he was the same. The soldiers were very afraid, but he was even more afraid. However, he knew that if they ran away, what would be waiting for them behind them? The order he received made it impossible for him to have any other thoughts. Even if the zombies' corpses were piled up to the same height as the position, they were not allowed to leave. Even if they were to die, they had to die in the position.
The shouts from the loudspeaker were not very effective, the soldiers were still afraid, especially when the zombies rushed past their feet, which gave them the illusion that their escape route was cut off. Almost no one could stay calm when their escape route was cut off. Although they had not experienced such a large zombie tide, they all knew how terrible these dull black guys were. The more they knew about zombies, the more they knew how terrible these dull black guys were. At this moment, the morale of the soldiers was a little shaken.
Then gunshots came from the wall behind them. The loud gunshots comforted them, but it also reminded them that they were not separated by zombies, it was just an illusion.
At this time, mortar teams came up from the hilltop on both sides. These teams were all soldiers of the new era. These soldiers were very tired, but their eyes were burning. After they rushed up the position with the mortars, they did not care about the other guards, but just used the binoculars to observe the size of the zombie tide at the foot of the hill. The focus of observation was the hill of corpses that formed a gentle slope.
The soldiers did not understand why these soldiers of the new era came up. Seeing that they brought rare support weapons, they did not show any hostility. In front of the common enemy, they used the common bloodline to gain initial trust.
The officers anxiously surrounded the elite soldiers of the new era. All the support firepower was behind them, ready to be used in the big battle. They were only the support force to delay the time. Whether they could delay the time or not was not up to them, it depended on whether the zombies agreed or not. From the current situation, it seemed that it was very difficult to delay the time for eight hours. Guarding for one and a half hours already made them anxious, and the official attack had only started for an hour. God knows how they could survive the remaining six hours.
The new era soldiers quickly set up the mortars and opened the long ammunition box, revealing a row of three mortar shells. This kind of mortar shell was very strange. It was red and yellow, and there were rows of foreign language words. The three mortars were equipped with three ammunition boxes. If there were three mortars on both sides, New Era would only bring a total of 54 mortars. In this way, it seemed that it would not be useful at all.
After the mortar shell was sent into the barrel, a soft sound was heard. Except for the heavy firepower, everyone looked up at the landing point of the shell. They saw three black spots flying up from the hilltop on both sides, rushing high into the sky and falling toward the hill of corpses that was 500 meters away. Then the moment when they were about to land, they split into more than ten small black spots and evenly scattered on the hill of corpses, making the surrounding soldiers disappointed.
There was no fire, no smoke, no explosion, as if it was just a joke. New Era soldiers didn't care and fired the remaining shells one by one. Each shell fell on a different point on the hill of corpses, and each shell split into small black spots and scattered among the squirming zombies.
After the 54 mortar shells were fired, the soldiers on the position fired while looking at the mortar team next to them. It seemed that they wanted to understand what they wanted to do.
New Era soldiers didn't let them down. The leader of the mortar team held a binoculars and a controller in his hand. When his thumb pressed on the controller, the hill of corpses suddenly flashed, and then black smoke rose from the hill of corpses. The next moment, countless zombies were wrapped in flames. The flames spread around the two to three kilometers long hill of corpses, and finally connected with each other to form a huge wall of fire. Every zombie that rolled over the wall of fire would be lit up into a torch.
The soldiers on the position suddenly cheered. The flames burned on the hill of corpses, and the huge flame rose more than ten meters. The black smoke almost shrouded the entire hillside. As the flames burned the fine vegetation on the hillside, the spreading sea of fire gradually spread up the hillside.
At this time, the zombies that gathered below were attacked from two sides at the same time. One side was the spreading wall of fire. The wall of fire followed the bodies of the zombies on the road and approached the other zombies. The firepower on the hilltop erupted with new intensity, and the zombies that were forced back by the flames kept falling down, becoming fuel for the sea of fire.
The sea of fire divided the zombie tide, and more and more zombies fell under the muzzle of the guns. More and more zombies ran in the sea of fire, forming a torch that ignited the other zombies. At this moment, some soldiers even believed that as long as they had these flames, they could kill all the zombies here.
