Facing the army of zombies that were following behind the decoy troops and rushing towards their positions, the troops of the self-help army opened fire instantly. The powerful firepower of the new assault rifle made the charging zombie army suddenly stunned, as if it had crashed into a real wall. The zombies that rushed in front fell to the ground in pieces.

The firepower of the two infantry regiments, which had been reequipped with new weapons, was really not covered. Just after each person shoots one magazine of bullets, 300,000 rounds of bullets are fired! It's really like splashing water.

With this scale of firepower, even Chen Yuan himself was very surprised.

The development of this assault rifle was Chen Yuan's attention, yes. However, in the previous life, he was only fortunate to have seen the real thing once, and he knew the general principle and direction, and he had never seen such a large-scale application. Since the two regiments of the Salvation Army changed their equipment, it was also the first time that they were put into actual combat on a large scale.

The effect is really amazing.

At this time, although the zombies also began to fight back. But it didn't work, 20,000 elite zombies against 8,000 powerful human infantry.

The battle lasted less than a few minutes, and the elite zombies were beaten to less than 5,000, and this was when the corpse general controlled these zombies to consciously dodge bullets. Otherwise, if those brainless ordinary zombies rush up, even if there are fifty or sixty thousand, they will be wiped out in minutes.

However, at this time, Chen Yuan did not take advantage of the victory to pursue, but ordered the 1st Regiment, the 3rd Regiment and the Special Service Brigade, which had the strongest firepower, to quietly withdraw from the battle.

Because at this time, they had re-established contact with the Oil City, and Du Mei already knew about the plan of the Steel Castle.

In the hot feeling on the secretary's face because he misunderstood the self-salvation army.

Units of the 1st and 3rd Regiments of the Self-Salvation Army and the Special Service Brigade have already begun operations.

Under the leadership of Chen Yuan, they first headed north and then east, preparing to bypass the main force north of the zombie group, rush into Oil City from the east, and assist the defenders of Oil City in defense.

This is the plan drawn up by Liu Jinlong and them.

Although now, with the combat effectiveness of the self-rescue army, it is not necessarily impossible to defeat this elite zombie army in the wild. But there are walls on the oil city side, so of course they have to be used. They're here to rescue, not to fight the zombies.

At this time, even more than 400 vehicles that formed a temporary position gradually drove away, which was to attract the attention of the zombies and cover the troops of the 1st and 3rd regiments.

The remaining 2 and 4 regiments had a much weaker firepower.

At this time, although the corpse general did not know why the troops of the self-rescue army fought well, they suddenly withdrew. But it saw it as a good opportunity.

So he immediately sent another 20,000 elite zombies to rush to reinforcements.

Under such circumstances, the troops of the 2nd and 4th regiments of the Self-Salvation Army began to flee again.

This time they headed west.

The corpses will be overjoyed, without vehicles, human beings can't outrun zombies by their legs alone, because they always have a time when they are tired, but zombies can't.

What the corpse will not know, however, is that to the west of Oil City, about 2 kilometers away, there is a large dense lake field. There are hundreds of lakes large and small.

The terrain here is complex, which is very conducive to human troops fighting movement warfare and guerrilla warfare.

As soon as the troops of the 2 and 4 regiments arrived, they separated. They entered the lake from two different paths, and played a game of cat and mouse with the terrain and zombie army.

"Haha! Come on, come and chase us! "The warriors shuttle back and forth flexibly in the narrow passages of the lake, while the zombies are too numerous to move. They even squeezed around, leaving many of their kind overboard. The soldiers of the Self-Salvation Army laughed triumphantly.

In the end, the troops of the two regiments took 25,000 zombies around the lake, and not only wiped out about 7,000 of their zombies. And the remaining 18,000 zombies were fainted in the lake. He rushed out of the west side of the lake and made another detour to the main battlefield of Oil City.

At this time, the 1st Regiment, the 3rd Regiment and the Special Service Brigade of the Self-Rescue Army, equipped with new weapons, had also made a long detour and arrived at the east of the oil city smoothly and quietly.

Only a force of less than 3,000 zombies was besieging the city gates, but they did not attack.

The troops of the Self-Salvation Army launched a sneak attack from behind them, and under the superior strength and fierce firepower, the 3,000 zombies were almost wiped out in an instant.

And then they immediately rushed to the east gate of the oil city.

Here Du Mei has personally brought someone to answer.

So the troops of the Self-Salvation Army successfully entered the oil city.

"Chief Chen Bao, thank you for coming!" Seeing Chen Yuan, Du Mei stepped forward and stretched out a pair of beautiful white and tender hands to shake Chen Yuan tightly. Even if she was already a powerful woman before the end of the world, she was a beautiful big sister who eats both black and white. But when she really faced the siege of hundreds of thousands of zombies, she also seemed lonely and helpless. Fortunately, Chen Yuan appeared at this time.

Chen Yuan smiled and said, "City Lord Du doesn't need to be polite. We'll talk about these things later, but the important thing now is to destroy the zombies outside the city first. The zombies we've lured away are now trapped in the lake to the west, but it shouldn't be long before they get back. So we're going to hurry up and launch an attack on the zombies that are left out there right now. ”

"Hmmm! Good! Let's go this way. At this time, Du Mei naturally obeyed Chen Yuan's words. With Chen Yuan, their troops rushed to the northern city wall.

At this time, on the northern city wall, there was still a fierce battle.

Chen Yuan asked by the way, "City Lord Du, what about the ice mutant zombie?" You're running to pick us up, is anyone dealing with that ice mutant zombie? ”

"It's okay, it's already gone!" Du Meiqiao's face was slightly red, and she said regretfully: "I'm ashamed to say that the five of us besieged an ice mutant zombie and failed to keep it." ”

Chen Yuan nodded and said, "It's nothing, the mutant zombies have an advantage over us human abilities. But it can't escape. ”

Subsequently, the troops of the self-salvation army climbed the city wall.

At this time, due to the resumption of one-line combat, the zombies' attack on Oil City has returned to the initial fierce stage.

Although they had been driven down once by the defenders of Oil City before, the mountain of corpses was still there, and it was even higher.

A large number of zombies poured up the slope again and began to storm the walls again. In two places, the zombies have already stood on the walls again.

However, at this moment, the troops of the Self-Salvation Army suddenly rushed behind and killed.

The new weapon fired, and the powerful firepower instantly suppressed the zombies that had rushed up the city wall. The zombies rushing up under the city wall also fell one by one, and the threat became invisible.

"Huh? How can the people of the Self-Salvation Army be in our city? Didn't they run away? Even the defenders of Oil City themselves were stunned.

The communication system of the Oil City is not as advanced as that of the Self-Rescue Army, and most of the defenders of the Oil City at this time still thought that the troops of the Iron Citadel had fled before.

I didn't expect that they would suddenly appear behind them at this time, and use the most fierce firepower to help them resolve the crisis in an instant!
