Shen Bai, who has been injected with genetic medicine, has several times the hearing of ordinary people, and his hearing is almost close to that of dogs and other animals, so he can clearly hear a large number of footsteps.

A few minutes later, a large group of zombies appeared under the light.

Shen Bai's eyes narrowed slightly, but he didn't let the soldiers fire at the first time.

"What is this? Tempting? ”

The corpse group did not attack at the first time, and the zombie group that appeared in the light was only four or five thousand.

The zombie group of five thousand may be a large number for ordinary survivors, but it is not worth mentioning at all for the soldiers who are waiting for the battle.

They don't even need to fire, and the zombies don't pose any threat to the base's walls.

"Since you want to be tempted, let you test enough. It just so happened that I took these zombies. ”

Shen Bai smiled slightly, and did not order the soldiers to open fire from beginning to end.

Under the bright light, the more than 5,000 zombies staggered to the wall, raising their hands one after another, trying to grab the soldiers standing above the wall.

The reinforced concrete fence, which can be up to three meters high, is a completely insurmountable obstacle for them.

"Have the soldiers shoot these zombie spots. Remember, it's important to keep a hit rate. ”

Shen Bai said to Ada Wang.

"Yes, Commander."

Ada Wang replied, and immediately transmitted the order to all the soldiers via satellite.

Suddenly, all the mercenaries and soldiers stepped forward, raised their guns and aimed at the zombies directly below, aimed and then pulled the trigger.

"Phew! Bang! Woo ......"

The gunshots rang out constantly, but the sound was not dense.

Strictly abide by Shen Bai's requirements, save bullets, and ensure that when a zombie is killed with one shot, each soldier will shoot only after aiming carefully.

The zombies that have reached the bottom of the wall are no longer at any distance from the soldiers themselves, and the height difference between the soldiers shooting down from the wall is only more than one meter, even if there is no rank, it is impossible to shoot at this distance.

Hundreds of soldiers opened fire at the same time, although the frequency was not fast, but after a while, the more than 5,000 zombies were quickly cleared.

Obviously, the intelligent zombies wanted to use a small number of zombies to test the strength of the base's defensive firepower, but Shen Bai was even more happy to do so.

It didn't take long for the group of more than 5,000 corpses used to test all the deaths, and there was silence for a moment on the side of the corpse tide, and then heavy and dense footsteps sounded again.

Shen Bai's expression changed slightly, because judging from the direction of the footsteps, the target of the zombie this time was not in the direction of the main entrance.

"It was reported that a large number of zombies were found approaching the south side of the base. The number is about 10,000. ”

Before Ida Wang's words fell, a large number of zombies appeared at the main gate where Shen Bai and the others were, that is, in the west.

It was actually attacked from both sides at the same time.

Shen Bai picked up an automatic rifle that had been placed in advance on the firearm rack on the side, pulled the bolt, and said to Ida Wang at the same time: "The command of the south side is up to you. Alice and I are in charge of the corpses at the main entrance. ”

"Yes, Commander."

Without the slightest hesitation, Ada Wang immediately rushed towards the southern wall with a group of soldiers.

At the same time, the sound of soldiers' shooting was already heard in the south.

Although during the day, the corpses had gathered all the zombies surrounding the base back to the position of the main entrance, but it was impossible for Shen Bai to really let the other positions go, whether it was except for the west side where the exit of the main gate was located, a certain number of soldiers were also placed on the walls of the other four directions.

Coupled with the group of soldiers taken by Ada Wang, even tens of thousands of zombies are enough to deal with it.

On the side of the main entrance, within the reach of the distant lights, a large number of zombies appeared again, and the number was more than when they were tested before.

Not only that, in the group of corpses, Shen Bai could also see the figures walking quickly.

That speed, it's obviously a T2 zombie.

Shen Bai's heart couldn't help jumping, and he hurriedly reminded Ida Wang Dao through the satellite: "T2 zombies have been found in the corpse group at the main entrance, so be sure to pay extra attention." ”

Unlike ordinary zombies, T2 zombies with strange speed and sharp claws can fly up walls, or even hang upside down on the ceiling.

The 3-meter-high wall is far less effective in front of them than it is against ordinary zombies.

Although the number of T2 zombies does not seem to be particularly large, once they climb the wall, they pose a big threat to the soldiers.

"Roger, Commander, if necessary, I will let the White Queen use the Sentinel Cannon to deal with the enemy."

Ida Wang's response sounded in his consciousness, and Shen Bai's heart settled for a moment, and he immediately clenched the automatic rifle in his hand.

The weapons placed on the wall have been adjusted and inspected by the soldiers in advance, and the bullets have been loaded, so that after the soldiers themselves run out of weapons and bullets, they can pick up spare weapons to fight as soon as possible.

In the past, soldiers used their own weapons and self-refresh ammunition to fight, so all the captured firearms and weapons would be stored, although there were not many each time, but over time, Shen Bai still accumulated some belongings.

To deal with these little minion zombies, Shen Bai naturally would not waste the special sniper bullets of his precious anti-materiel sniper rifle, and it was just right to use a standard automatic rifle.

"Phew! Bang! ”

Before Shen Bai could start aiming, on the other side, Alice had already pulled out a special pistol from the holster like lightning and fired at the corpses in the distance.

The amazing dynamic vision allowed Shen Bai to capture it instantly, accompanied by Alice's gunshots, the two T2 zombies hiding in the corpse group were shot in the head and fell to the ground in convulsions.

"Hit it really accurately."

Shen Bai sighed, then raised his gun to aim and pulled the trigger.

"Bang!"

The muzzle of the automatic rifle shoots out tongues of fire, and bullets shoot out, hitting a T2 with precision.

In terms of marksmanship, Shen Bai, who doesn't have much shooting practice, is actually far from being able to enter the house, and he is completely incomparable with shooting masters such as Alice and snipers.

But the super dynamic vision, reflex nerves, and muscle control ability that the genetic potion brought to him made Shen Bai easily surpass most shooters who had practiced a lot in shooting.

Along with Alice and Shen Bai's shooting, the other soldiers also chose to open fire after the corpses approached a certain distance.

This time is different from just now, the corpses are mixed with T2 that can climb over the wall, so they must not be allowed to come under the wall easily, even if they shoot from a distance of hundreds of meters, the accuracy will be reduced, and some bullets will be wasted.

Under the rain of bullets, this large number of corpses were all shot before they reached the wall.

But before Shen Bai and the others could take a breath, the attack of the corpse tide came again.

"After one batch is finished, then the next batch, is this going to use low-level ordinary zombies mixed with a small number of T2 zombies to continuously consume the soldiers' ammunition?"

Shen Bai changed the magazine while silently thinking about the other party's thoughts in his heart.

More than 100,000 zombies swarmed up, a huge number, although they could completely rush under the wall under the rain of bullets, but in that case, the space for zombies to move was too small.

T2 zombies will be crowded with corpses without any room to move, and even T3 zombies will have a hard time trying to get close to the wall.

And when the zombies are too dense, it also increases the probability of being hit, but it is not as good as a wave, there is a lot of room for activity between zombies and zombies, and it will be more difficult to aim and fire when defending.
