Roar, roar, roar!

The roar of the zombies became louder and louder, spreading throughout the base, making some people who could have rested unable to sleep at all, and their hearts were uneasy.

The survivor squads standing on the city wall looked at the overwhelming tide of corpses, and their palms were in a cold sweat.

Time passed, more and more soldiers were withdrawn, and the speed of retreat became faster and faster.

But fortunately, as they retreated, the defensive line they needed to defend was also constantly shrinking, which did not lead to the collapse of the defensive line.

About another hour later, at about 8 p.m., the vanguard of the corpse tide finally approached Yin'an Bridge.

At this time, all the ordinary soldiers had withdrawn, and now only the dragon tooth team and the special operations group were left in charge of the broken end.

In the Dragon's Tooth team, those members with slashing weapons stood in front, fending off the swarming corpse tide while retreating in an orderly manner.

Behind these members, there are at least two soldiers with guns in their hands, ready to shoot for them.

Under such circumstances, as long as the formation is not chaotic, no matter how turbulent the offensive of the corpse tide is, it will not be able to break through their formation.

Even a mutated zombie like Deathclaw didn't dare to come and attack at will.

Perhaps when the Deathclaw is aimed at a normal soldier, it can kill them with a single blow and flee immediately, leaving these soldiers with little chance to fight back.

But the members of the Dragon Tooth Team are different, these people are all Xu Wenjie, who has been screened out of the entire Xin'an City base, and their talents are higher than forty elites.

Such a talent, even if you look at all human beings, is definitely at the backbone level, so even if it is against the death claw, they can compete with one or two.

And as long as they are not killed in seconds, then the soldiers behind can reinforce them in time, and the power of automatic rifles, a shuttle bullet passes, even if it is a second-order death claw, it will be seriously injured.

Of course, even if the Dragon Tooth Clans cooperate with the Special Operations Group, they can only protect themselves, and if they want to carry the tide of corpses here in the suburbs, it is impossible.

The team continued to retreat, and after about fifteen minutes, the soldiers of the Dragon's Tooth Combat Team and the Special Operations Regiment also withdrew to Yin'an Bridge. At this point, it can be said that it is their home turf.

The width of Yin'an Bridge is only five meters, and with cars piled up on both sides, only a two-meter-wide passage remains in the middle.

In such a narrow place, not to mention a huge tide of corpses, even the Dragon Tooth Clans or Special Operations Regiments can't squeeze in.

These two teams only left fifty men each to defend the town, and the rest of the soldiers withdrew to the city wall.

By this time the gates of the city wall had been tightly closed, but there were ropes hanging from both sides, and the soldiers could climb up these ropes at any time if they needed to.

Da-da-da-da!

When the large army of corpses flocked to Xin'an Bridge, they finally received their first head-on blow.

The two heavy machine guns mounted on the city wall, spitting out long tongues of fire, instantly tore dozens of zombies rushing onto Yin'an Bridge to pieces.

A 12.7mm bullet can easily penetrate even a reinforced concrete wall, which is simply not something that these ordinary zombies can resist.

Even a few of the dead claws and predators that were mixed in with the corpse tide were swept to death by random guns.

This scene immediately boosted the morale of the survivor team on the city wall, which at least proved that they had the strength to resist the tide of corpses, and they were not completely unable to resist like before, and could only retreat one after another.

Of course, the faces of those soldiers were still serious, because only they knew how scarce their military's ammunition reserves were.

Machine guns can't be fired sustainably at all, so in the end, it depends on the strength of the Dragon's Tooth Squad and the Special Operations Regiment.

At this time, not only these soldiers were watching nervously, but even heavyweights such as Peng De, Wu Hai, and Tang Pengyun also came to the top of the city wall to watch this scene.

The machine-gun fire only lasted for thirty seconds before stopping, and although the time for this strafing was short, it was enough for the soldiers of the Dragon's Tooth Combat Team and the Special Operations Regiment to reorganize their formation.

When the strafing stopped, countless zombies rushed to Yin'an Bridge again, but even if there were more than two million zombies on the opposite side, there were less than two meters left in the passage of Xin'an Bridge, no matter how many zombies squeezed in, it would be good to have four or five zombies attack at the same time.

Puff puff!

Two members of the Dragon's Tooth Clans stood at the front, holding the cutting broadsword in their hands and swinging it, and the four or five zombies in the front fell to the ground in unison.

Then the zombies in the back poured up, and it was the same ending.

The two members of the Dragon's Tooth Clan alone withstood the pressure of the corpse tide in front of them. The soldiers of the special operations regiment in the back opened fire one after another to relieve their pressure.

All of a sudden, these zombies that kept rushing in, in this narrow space, fell like cutting wheat, and they couldn't move forward at all.

This scene immediately made all the officers, soldiers and even survivors on the city wall cheer.

The excellent geographical location of the Xin'an City base once again played its miraculous effect. Here, it's really a matter of time.

As long as the Dragon's Tooth Clan's side takes turns to replace manpower and keep the combatants in the best fighting condition at all times, then it is impossible for these corpse tides to come over.

Of course, the only trouble may be the cleanup of zombies, but there is already quite enough experience in this new resettlement base.

After seeing that the Dragon Tooth Clan's team had stabilized their position, a platoon of soldiers suddenly rushed to the Yin'an Bridge in the direction of the base, skillfully got under the cars on both sides, dragged the corpses of the zombies in, took out the evolved meat, and then threw the corpses into the Xin'an River.

"Very good, in this situation now, it is almost the most ideal state, immediately implement Plan A and clean up the mutated zombies along the river." Peng De stood on the city wall and watched the battle situation under the Yin'an Bridge, and gave an order.

"Yes!" With a smile on his face, Wu Hai saluted a military salute and immediately went to carry it out.

Not long after Wu Hai went down, a group of fifty soldiers soon came up.

And everywhere they passed, many people looked sideways, not because of how powerful these soldiers were, but because the weapons in their hands were all sniper rifles!

Let the sniper shoot the mutated zombies on the opposite side, this is Pender's plan, simple and effective.

In the previous defensive battle, the threat of snipers to mutant zombies was seen by everyone.

Except for the two zombies, Roshan and Abomination, there are no other mutated zombies that can withstand the bullets of sniper rifles.

Not even a powerful death claw.
