Chapter 159

This is the first large-scale defense war commanded by Cai Wenjie. Therefore, Cai Wenjie will make full use of this battle without reservation. With the consumption of ammunition, Cai Wenjie will obtain more and more points, and these points will not be retained. The ammunition required for defense is limited, so Cai Wenjie must exchange additional money.

To this end, Cai Wenjie specially built a simple ammunition warehouse first. Once the ammunition consumption exceeds 50% of the whole, Cai Wenjie will immediately go to the simple ammunition warehouse to exchange ammunition and accessories that need to be replaced.

Now the whole defense war has fallen into a stalemate. The zombies are still charging forward desperately, and the defense forces are also desperately blocking these zombies. The armed helicopters and UAVs in the air have finished ammunition and are returning to the gathering area for reloading. The barrel of the machine gun has been hot enough to need to be replaced or cooled urgently.

"Report! The barrel of the machine gun is about to be scrapped!"

A soldier who controlled the heavy machine gun shouted. When Cai Wenjie heard it, he ordered without hesitation

"Gatling machine gun fire! Grenade launcher and mortar fire! Buy some time, and the remaining machine guns will cease fire immediately and replace the barrel!"

"Yes!"

Finally, one hour after the start of the battle, the soldiers' firepower appeared in a weak area, and the zombies also saw the opportunity to start a fierce attack. Of course, this is only a fierce attack that humans think. The zombies have maintained this attack frequency from the beginning.

When the soldiers replaced the barrel of the machine gun that was about to be scrapped, the zombies had touched it from the first 400 meters to now 200 meters away, but that was all. There was a lack of 20 heavy machine guns. Although the firepower was somewhat weakened, it was under the intensive bombing of Gatling machine guns, grenade launchers and mortars, Zombies can't break through the remaining distance.

Moreover, with the replacement of the barrel of the machine gun, the firepower has been raised to the original level again. The zombies have been directly beaten back for a distance of 50 meters. So far, the number of zombies has been directly weakened from about 25000 at the beginning to 12000. Most of the zombies died in the flames in the depression.

The battle fell into a stalemate again. The zombies couldn't rush up and the soldiers couldn't fight down. The distance between the zombies and the gathering place was kept at about 200 meters.

Looking at the stalemate of the defense war again, Cai Wenjie's eyebrows rose, then his expression became serious as if he had made up his mind, and said to the walkie talkie.

"Order! Mortar team to replace special shells!"

"Yes!"

The special shells referred to here are actually special shells such as white phosphorus shells and sulfuric acid shells.

Immediately, the mortar bombing on the battlefield stopped, and the zombies took the opportunity to narrow the distance again, but within five minutes, the special sound of the mortar rang, but the mortar shell did not explode on the ground as usual, but exploded in the air of the corpse group. At the same time, with the explosion, white smoke appeared over the corpse group, It was scattered among the corpses below like heaven and women scattered flowers.

White phosphorus has strong irritation, extremely low ignition point and strong flammability. Once in contact with oxygen, it will burn. It will emit yellow flame and strong smoke. It can burn substances that are difficult to burn ordinary combustion materials. The combustion temperature can reach more than 1000 ℃, which is enough to destroy all organisms within the effective range.

After the human body encounters the burning white phosphorus, the white phosphorus will penetrate the human flesh layer and reach the bones. Zombies are no exception. Zombies contaminated with white phosphorus fall to the ground in less than a few seconds. Most of the flesh and blood of the body are directly burned through due to white phosphorus, resulting in inability to stand up at all. Even some unlucky zombies are directly burned through the skull by white phosphorus and die in situ.

Because the poisonous gas produced by the white phosphorus bomb may affect the soldiers with the wind, Cai Wenjie ordered the white phosphorus bomb to be fired and asked the soldiers to wear gas masks at the same time.

A total of three rounds of white phosphorus shells were fired, and more was wasted. The mortar team in the back row changed back to ordinary mortar shells. At this time, on the battlefield, most of the zombies contaminated with white phosphorus fell directly to the ground and burned silently, while the zombies that had not been affected by white phosphorus shells continued to charge forward on the burning zombies.

However, because there were too many fallen zombies, the speed of the charge was greatly hit and had to move forward hard, which suddenly reduced the pressure of the soldiers. Cai Wenjie didn't want to waste this opportunity, so he picked up a rocket launcher placed at random and aimed at the zombies in the distance.

After Cai Wenjie pulled the trigger of the rocket launcher, the rocket flew out and accurately hit the zombie who was struggling to step on the bodies of the same kind.

"Boom!"

When the rocket hit the zombie, it did not produce a huge explosion, but ejected a strange liquid. In fact, this is the combustion aid, which will engulf the surrounding zombie by fire. Moreover, this combustion aid can not be extinguished by ordinary methods, but can only burn naturally until there is nothing to burn.

The zombies who had just been hit by the white phosphorus bullet and could not stand up were sprayed with combustion supporting agent, which immediately became a source of fire. The whole road leading to the gathering place was swallowed up by the fire. Countless zombies howled and were ignited by the fire and finally burned to death.

But even so, it still couldn't stop the pace of zombies. The zombies behind were still crazy and pushed forward. Soon, zombies broke through the flame again and continued to rush to the gathering place, and then they were accurately blasted by machine guns.

Dead zombies have piled up like a mountain at 200 meters. This height has reached at least two meters, and it is still increasing. Although the flame is burning these corpses a little, it is impossible in a short time.

At this time, the armed helicopters that had gone to replenish ammunition returned to the battlefield. However, they completed the replenishment of ammunition within a time, and this time the Rockets were replaced with napalm bombs.

The armed helicopter that returned to the battlefield for the first time did not have any superfluous action, but moved all the way along the road from a hundred meters away from the intersection of the gathering place, and started dropping bombs while moving. Napalm bombs began to explode on the road, strengthening the burning flame on the road for another stage.

This time, even the zombies in the distance were not spared. They directly dropped napalm on their heads, allowing them to taste the pain of the zombies in front.

The two armed helicopters dropped at least dozens of napalm incendiary bombs, which directly turned the hundreds of meters long road into a sea of fire, or the kind of unquenchable fire, which gave the zombies a great blow. They didn't need the soldiers to shoot. As long as they crossed the hundreds of meters of sea of fire, they could destroy most of the zombies.
