"The two tanks retreated, moved back 500 meters, and joined the mortar battery."

In the face of the impact of thousands of powerful zombies, the two tanks will not play a role, but may be overturned by zombies. So after the zombie hordes charged, Chen Yuan decisively gave the transfer order to the two tanks.

The zombies rushed fast on the hard Gobi Desert. Even though it's winter, the speed is comparable to that of a human running 400 meters. It only took a little more than 1 minute, and the zombies had already rushed over a distance of 500 meters. And sure enough, as Xu Kai said, their charging formation was very scattered. In fact, even if mortar shelling is used, casualties will be very limited.

So Chen Yuan simply gave up ordering the mortar company to bombard the advancing zombie group.

500 meters, 400 meters, 300 meters, 200 meters, zombies are constantly approaching. The soldiers couldn't help but tighten their guns.

"Fire!" When the zombies rushed 150 meters away, Chen Yuan finally gave the order to fire to the other fighters.

In an instant, nearly 700 fighters opened fire almost simultaneously, assault rifles, light machine guns, heavy machine guns, all kinds of gunfire rang out. A large number of bullets rained down on the zombies on the opposite side.

Many of the zombies in the charge were shot and fell down as soon as possible. However, due to the effect of inertia, these fallen zombies did not stop immediately, but continued to roll forward on the Gobi Desert like stones rolling down the hillside. It's spectacular, it's almost like something out of a movie. But in fact, this brought unexpected trouble to the troops of the Self-Salvation Army!

The Gobi Desert here is dry all year round, and a slight stamping of your feet can kick up a lot of dust. Not to mention the hordes of zombies in the charge and the zombies rolling on the ground. The dust in the sky was raised as the zombies advanced, and soon formed a patch, like a thick fog. Blinded the view of the fighters of the Self-Salvation Army.

Seeing such a situation, Chen Yuan secretly said in his heart, the situation is not good!

If you can't see zombies clearly, the speed and accuracy of shooting will naturally be greatly reduced. The fighters began to get a little nervous. No one has encountered a similar situation in the Northeast, and I didn't expect it to be like this before. The situation exceeded their expectations, and everyone was a little overwhelmed. Some fighters simply stopped shooting.

Chen Yuan immediately shouted: "Don't stop, keep shooting!" Whether you see it or not, the zombies are all in the dust mist! ”

At this time, it was naturally not the time to be careful about wasting bullets, Chen Yuan was worried that if this continued, there would definitely be a lot of zombies rushing under their city walls.

However, the walls here are not very high. Coupled with the trench that has sunken down, it is only 7 meters in total, and the zombies will be able to climb up quickly.

So at this time, Chen Yuan immediately mobilized his ice ability and swung it hard. 30 meters away on the ground, the ice ability begins to freeze. And the ice surface spreads rapidly, and in a few seconds, a huge ice surface with a radius of 20 meters has been formed.

The ground is covered with a layer of ice, and the dust naturally cannot be raised! Moreover, zombies are also easy to slip when they suddenly step on the ice, which can buy some time for the soldiers of the self-rescue army.

However, the ice surface with a radius of 20 meters is already the limit of Chen Yuan's current ice ability.

So he immediately ran to the right and recreated a piece of ice 40 meters away.

It's just that the zombie horde in the charge didn't give him much time. Although his speed was fast, before the zombies rushed in, he only had time to create three of these ice surfaces, and the total length of the combined ones was only 120 meters, only a little more than a third of the city wall.

By this time, many zombies had already begun to rush onto the ice. Just as Chen Yuan expected, as soon as they stepped on the ice, the zombies slid violently under their feet, and their whole bodies flew up, and then they fell down one after another like dumplings, falling heavily on the ice.

Zombies don't have the same sense of balance as humans, let alone rushing to the ice at such a fast speed! I don't know if I'm alive or dead.

In a short time, zombies fell to the ground on the ice. Or even in a pile.

This gave the soldiers a great opportunity, and those fallen zombies, without speed and without the influence of dust and fog, instantly became live targets. He was shot through the head by a bullet from a soldier and died 40 meters from the city wall.

But on the other hand, Chen Yuan's defense line before he had time to create an ice surface was not so easy.

With the help of the influence of dust and mist, the zombies quickly rushed to the front of the city wall.

They jumped down the ditch, and in a short time a large number of zombies gathered under the city walls, and began to struggle to climb the walls.

The soldiers opened fire one after another, knocking down the zombies that were climbing up the stacked arhats. However, the distance is too close, the zombies move fast, and it is not easy to accurately hit the head. Many zombies are only temporarily beaten, as long as they don't die, they will continue to climb up desperately after standing up.

Fortunately, this is a desert with relatively few materials that can be used to make bows and arrows, so there are not many archers in the zombie group. There are significantly fewer arrows fired than the zombie hordes elsewhere. The strength of the strengthened self-rescue army soldiers is not weak, just like the ancient generals, using the weapons in their hands to pick up arrows or dodge, many of which can effectively defend. The casualties were not serious.

But what's worse is that zombies have already begun to attack the city walls.

Only the outermost layer of the city, about 30 centimeters thick, was made of "stone" and there was no adhesive. The zombie hit the stone wall with four or five times the force, and suddenly hit the wall that had not been reinforced. Many small rocks have begun to shake downward.

In particular, those fortified species pose a great threat to the city walls.

The effect of Dust Mist on Snipers is the same, and many Augments use the cover of Dust Mist to dodge Sniper attacks and rush under the walls. The powerful power of the giant corpse can shatter the stone wall with a single punch. The place that has been reinforced by Chen Shuyuan is okay, and the front city wall is like a whole, and it is easy to move.

But those places that have not yet come to remember to reinforce, it only takes two or three strokes for the stone walls to begin to crumble. Although not very serious. But it also startled the warriors on the city walls.

"Attack the Giant Corpse!" A nearby squad leader anxiously gave orders to the fighters under his command.

"Hurry up, we can't let it continue to attack the walls!" A new soldier with little combat experience shouted at the group as he opened fire.

"it!" The old soldier was not so nervous, and he was laughing as he fired, and his mouth was full of swearing.

The attack of the combined corpse is not weak, plus they have many arms, they can protect their heads well, and it is not easy to attack.

As a result, some of the soldiers began to throw grenades under the city walls, and the bullets could not reach the head of the corpse, and they would kill it.

The guns and acid corpses that arrived also began to exert their power, and they launched attacks on the self-rescue army soldiers on the city wall, and the casualties began to increase!

In addition, the reptilian corpses in the zombie group have also begun to climb the city wall, and their speed is extremely fast. The 7-meter-high city wall was climbed up by it almost in the blink of an eye.

At the same time, Xu Kai and Wei Chen, who were distributed in different parts of the city wall, also moved.

Lightning slashed across the city wall from time to time, Jiang Wenli's fireballs continued to shoot out like machine guns, and Wei Chen's golden pupils often flashed, aiming at the zombie group was a shot, and it was often able to accurately hit the key points of the strengthened zombies.

Daha picks on those climbing corpses that rush to the city wall. With Daha's combat effectiveness, crawling corpses are nothing in front of it.

It's just that there are too many fortified species. There are more than 2,000 zombies, and there are no less than 25 of them. And there are only a few people with the ability of the human army, and it is inevitable that there will be times when one or the other is lost, and the casualties of the self-help army on the city wall will begin to increase. And something worse soon happened.
