The lured zombie hordes have already arrived near the position of the Self-Salvation Army, and when they arrive here, they will naturally be attracted by the troops of the Self-Rescue Army, and then attack the defense line of the Self-Rescue Army.

The five cars in Wulian City that were responsible for luring the zombie herd saw that the plan had been successful, so they immediately let go of the bait that was dragging behind and prepared to speed up their escape.

But how could the troops of the Self-Salvation Army easily let go of these bastard-like guys!

On the orders of Chen Yuan, the shelling against them soon began.

The first to fire was the tank units.

Since the opponent is still two kilometers away from the position of the self-rescue army, and it is moving sideways at high speed, the speed is more than 100 kilometers per hour! Therefore, in order to hit them, the tank unit of the Self-Salvation Army used 15 tanks to shell these 5 vehicles at one time. Among them are three advanced Type 99 main battle tanks.

"Boom ......"

In the fierce roar, 15 shells were fired one after another, and the momentum was magnificent. In the blink of an eye, shells rained down on the heads of these fleeing vehicles, and then there was a violent explosion.

In just one round of shelling, four of the five vehicles that were fleeing from Wulian City were destroyed.

Three of them were directly hit by the shells of the self-rescue army, and they were blown up into scrap metal on the spot! The people inside are also finished! The defense of a normal car against shells is basically 0.

In addition, there was a car that was forced to avoid by shells, and the frightened driver made a mistake in his own operation, causing the vehicle to overturn.

Although the car overturned, the people in the car were fine. But when the car overturned, they naturally couldn't run. Liu Haitao's subordinates in the car cried one after another, this is not what Liu Haitao said when he asked them to carry out the task!

But at this point, no matter how much they call it, it's useless. The surrounding zombies quickly pounced on them and surrounded them. These are just ordinary cars, and they were dismantled into a pile of parts by the rampaging hordes of zombies in three or two clicks. The results of the people in the car can be imagined.

And the remaining car did not escape the second round of shelling by the tank units of the Self-Salvation Army.

Next, the artillery fire of the self-rescue army did not stop, but became more intense.

Because it didn't take long for a large number of zombies to gradually gather around these 5 cars, which became real bait. This is a great opportunity.

As a result, the remaining tanks of the Self-Salvation Army, as well as mortar and long-range artillery units, were also added. Hundreds of shells flew from their respective directions to the hordes of zombies gathered around these vehicles.

"Boom ......"

Carpet bombing, a large number of zombies were blown away. The soldiers who saw the self-help army had great confidence.

Yes, now they are no longer the time to count the shells on their fingers in the past, are they afraid that they can't beat the zombies with so many shells?

However, in the front-line headquarters, Chen Yuan had other plans. At this time, the vanguard of the zombie group was only 2 kilometers away from the position of the self-rescue army, and according to the current speed of the zombie group, it was estimated that it would rush to them within 6 minutes.

Although it seems that the shells of the self-rescue army have eliminated a lot of zombies now, compared to the huge base of the zombie group, this zombie killed is nothing! Eventually, they had to retreat to the mountains and continue to fight the zombies.

So Chen Yuan ordered the signal corps: "Order all battalions to load explosives on their respective positions, and each company should prepare a few barrels of gasoline to use when retreating." ”

"Yes!" The signal corps immediately conveyed Chen Yuan's order to the battalion commanders of each battalion. The troops also began active preparations.

Three minutes later, the vanguard of the zombies advanced to a position about 1 kilometer away from the position of the self-rescue army.

Chen Yuan immediately ordered all the snipers in the unit to open fire.

"Puff puff ......"

Sniper rifles with silencers are firing bullets, and the top priority is of course the enhanced zombies in the zombie horde.

At this time, the cannon corpses in the zombie group have also begun to attack, but there are not many of them.

Although the scale of this zombie group is large, most of them are wild monsters that do not have corpse control. By the way, there are very few enhanced species among them. There wasn't even a single flying corpse.

It is estimated that because the power of the flying corpses is small, although the speed can catch up with these vehicles that lure zombies, it can't help them, so they all give up halfway.

Due to the scarcity of numbers, the first wave of zombie shells fired at the positions of the self-rescue forces did not exceed 10. The troops of the Self-Salvation Army were protected by fortifications, so the attack of these artillery corpses did not cause any substantial damage to the troops of the Self-Salvation Army.

On the side of the Self-Salvation Army, the snipers of the two sniper squadrons and the two field infantry battalions succeeded one after another. There weren't many enhancements in the zombie group, and it didn't take long for most of them to be wiped out by the Self-Rescue Army.

More than two minutes later, the zombie group finally advanced to a position more than 200 meters away from the position of the self-rescue army.

But here, they entered the buffer zone set up in advance by the Self-Salvation Army troops.

So many troops stayed at the bottom of the hill for hours, but it was not just a fortified position.

The so-called buffer zone is actually composed of densely arranged ditches.

These ditches are not deep, at most 30 centimeters. It's not very wide, it's about 20 centimeters. There was also no water in it, not even straight, and it looked crooked. But it's very dense, and there is one every 20 centimeters. Dig all the way to the front of the positions of the self-help army. Looking at the position, if there are people with dense phobia and obsessive-compulsive disorder, it is estimated that they will be very irritable. But they knew it was a good thing to keep them alive.

Because of such uneven ground, not to mention zombies with poor balance, even if it's a human, you go and try it? It didn't take a few steps for you to fall on all fours.

So the zombies in the charge were as everyone expected, as soon as they rushed into the buffer zone, they rushed into the street in pieces. What's more, the buffer belt slows down the speed of the zombie horde's charge in an instant.

In such a buffer zone, the zombies can't be fast at all, and if they are fast, they will fall. And the zombies behind didn't know that they were still rushing forward desperately.

In a few moments, piles of zombies were concentrated at the edge of the buffer belt. It looks like waves crashing on the shore.

Chen Yuan immediately ordered the mortar and tank units to move the artillery fire towards the area. With such a dense group of zombies, as soon as their shells go down, most of them can kill seven or eight zombies, and as few as three or four. Thousands of them can be killed in a short time.

However, at the same time, there are still a large number of zombies continuing to rush towards the position of the self-help army. Even though their speed was much slower than before, more than a minute later, there were already zombies crawling to 150 meters away from the position of the self-rescue army.

"Fire!"

It was only then that Chen Yuan finally gave the order to fire to all the troops.

On the position, assault rifles and light and heavy machine guns suddenly rang out. Dense bullets poured like water towards the zombie hordes on the opposite side. A large number of zombies were hit by bullets and fell.
