Ma Zhonglin knew that this was mainly due to excessive use of the artillery barrel, which would reach a critical point of high temperature and must be cooled. Moreover, the life of the barrels produced by the steel plant was not as long as imagined, and some were firing dozens of missiles.

After the cannonball is fired, the barrel must be replaced. As a result, it is naturally intermittent.

Calculating the time, this intermittent bombardment has lasted for three hours, and the damage done to the zombies is fatal.

"There should be five or six hours before the zombies who escaped the gunfire will appear."

Ma Zhonglin didn't know why the military headquarters let all the soldiers enter the wall so early. Don't they know that it will take a long time for the zombies to reach the front? This kind of scorching sun will make you bored here for seven or eight hours.

If you don't adapt to the environment here, the horror of zombie attacks alone can lead to a rout just from soldiers who are comatose due to heat stroke.

But soon he knew it. The commanders at all levels were shouting, and the reconnaissance airships hovering in the sky transmitted the following situation to the troops on the ground.

Dots of zombies began to appear in the eyes of the soldiers. At first there were just a few, but then more and more became scattered and rushed towards the wall.

"All soldiers are ready to enter the battle. These are the advanced zombies at the forefront of the zombies. They move very fast and have separated from the large group of zombies. As soon as the battle begins, it will enter the most tragic moment, because you are facing,

They are all high-level zombies among zombies, and any hesitation will be fatal."

The officers were shouting, and even the platoon leader and company commander were all engaged in fighting, carrying their guns and starting to aim at the high-level zombies appearing in the distance.

The pursuit guns and recoilless guns on the wall did not fire, because the high-level zombies moved too fast and were very scattered, wasting a lot of shells, and their lethality was also very limited. So of course the elite ones were the first to show off their power.

Snipers. The two thousand snipers trained by Zhao Hongyuan are definitely the main force in dealing with zombies. They are scattered along this wall of hundreds of kilometers.

There was a loud "boom" and the dull sound of the 12.7mm heavy sniper rifle. A high-level zombie 1,200 meters away directly turned into a burst of debris while running, flying away and splashing around, giving people the feeling of being hit by a cannon.

Mosquito illusion.

But you have to admit that this large-caliber heavy sniper rifle has a very good effect on improving morale. The ferocious attack effect can often make people's blood boil and stimulate the crazy and bloody side of the soldiers. That kind of destruction

All momentum is the value of the heavy sniper rifle.

There were only a few snipers arranged on this section of the wall, but when faced with the zombies that were almost running straight forward, they were well-trained and displayed great combat capabilities. After every shot, there was always a

The head of the high-level zombie was blown off, and it rolled and fell into the sand.

Scattered high-level zombies, as if being called one by one, were constantly having their heads blasted off and fell down on the way forward.

Just a few snipers, facing an increasing number of high-level zombies, can't escape the trap. When a level 6 zombie slipped through the sniper's hand and appeared in a minefield placed on the sand.

, it rushed into the minefield without any pause.

Mines placed in a messy manner are impossible for zombies to identify, even if they are high-level zombies.

With a loud "boom", this zombie triggered a landmine. In the explosion, the entire lower body was blown to pieces, and the upper body was lifted high into the air. The smoke of the mine did not completely lift into the air.
