The sound of explosions and the miserable screams of mutant zombie beetles sounded in the house, one after another, which can be described as tragic. No matter how strong the leather armor of the mutant zombie beetle is, it has never been able to resist the corrosive gas generated by the explosion of the two biochemical grenades, and under the attack of the corrosive gas, the weak parts of the body began to fester, and a large area of green liquid stained the floor of the house green.

After the aftermath of the biochemical grenade dissipated, the roar of the Browning heavy machine gun still rang out, and the mutated zombie beetles at the edge of the house, without much damage, frantically pounced.

Of the eight mutant zombie beetles that rushed in, only three of them were not completely incapacitated in the explosion of the biochemical grenade, but they were also not lightly injured, and the layer of leather armor on their bodies was greatly reduced by the attack of corrosive gas.

"Da-da-da-" The Browning heavy machine gun's fire covered its body, easily piercing through the festering layer of leather armor, shattering its body.

Seeing their companions' bodies festering in the terrifying light mist, the large group of mutated zombie beetles outside the store was in a commotion, and they stared at those struggling and wailing companions, and their hearts were uneasy, and none of them dared to rush in.

"Tss

This scream was not only an outpouring of anger, but also an order to those evolutionary mutant zombie beetles, and after a brief period of uneasiness, the stagnant mutant zombie beetles moved again, and they screamed and rushed into the storefront.

As soon as these mutant zombie beetles entered the store, they rushed desperately in the direction of the second staircase, but fortunately, the stairs were very narrow, and there were already three injured mutant zombie beetles here, two of whose bodies had been completely destroyed by heavy machine guns, and the last one was still desperately rushing upward.

Under the control of Sun Yalei, the Browning heavy machine gun continued to vent bullets under the stairs, ruthlessly smashing the body of the mutant zombie beetle that was trying to rush up, making it unable to enter an inch.

As I stood next to the window, I could see the situation on the street clearly, and I saw the mutated zombie beetles rushing into the first floor again under the order of the mutated zombie beetle again, with a big smile on their faces.

"Bugs are bugs after all, and even if they complete their re-evolution, their IQ can't catch up with that of primates."

After speaking, his gaze withdrew from the window, and skillfully pressed the biochemical grenade, "...... Two...... Three"

The muffled explosion sounded again, and two biochemical grenades exploded on the first floor, playing the music of death.

"Boss, do you think we can wrap up this group of mutant zombie beetles?" Sun Yalei shouted loudly at me while controlling the Browning heavy machine gun to shoot at the mutant zombie beetle approaching the stairs, at this time his face was red, and the excitement in his heart also made his body tremble.

There are more than thirty mutant zombie beetles in front of them, even those human teams of hundreds of people dare not provoke them, but their small team of only four people dares to confront them head-on, and even caused great damage to the mutant zombie beetles. Such a seemingly crazy move, if it had been placed before, would not have dared to even think about it.

If the four of them really wrapped up these mutant zombie beetles, how many crystal nuclei could they swallow? I was thrilled when I thought about it.

I couldn't see any smile on my face, and I took out a biochemical grenade from my pocket, held it tightly in my hand, and watched intently at the actions of the mutated zombie beetles outside the window, and the third wave of mutant zombie beetles rushed in again.

"Whether you can wrap up this group of mutant zombie beetles depends on your performance, if you can successfully block the stairs and prevent a mutant zombie beetle from rushing up, none of these bugs will be able to escape."

"These brutes don't have any brains, they only know how to kill. Now that we have killed so many of its companions, they will never let us go, and they will not retreat if they don't kill a few of us, so as long as we cooperate properly, it is entirely possible to wrap up. Alas, it's a pity that there are so many biochemical grenades, I finally managed to get a few of them, and I'm going to use them up today. ”

Looking at the few biochemical grenades in my waist bag, my heart ached slightly, but when I thought of the large number of orange crystals, I felt much more comfortable.

"Boss, you can put a hundred hearts, with this big guy here, I won't be able to rush those mutated zombie beetles." Sun Yalei shouted happily.

In the third wave, five mutant zombie beetles frantically poured into the store under the urging of the mutant zombie beetle that evolved again, and as before, under the powerful fire of the Browning heavy machine gun, they finally failed to set foot on the stairs, and two biochemical grenades fell from the second floor and exploded in the mutant zombie beetle swarm.

The aftermath of the biochemical grenade has not yet subsided, and the fourth wave of mutant zombie beetles has rushed in, the same five, and at this time on the first floor, the injured mutant zombie beetles on the ground have been piled up, especially at the staircase, the corpses of six or seven mutant zombie beetles whose bodies were shattered by heavy machine guns are piled there, almost blocking the stairs.

In order to rush up to the second floor, the mutant zombie beetles who came in from behind had to get rid of the corpses of their companions, and in the process, the roar of the heavy machine guns was incessant, and the powerful firepower caused a lot of damage to these mutant zombie beetles.

Although the mutant zombie beetle was fierce, under this fierce fire, it still failed to rush up the stairs in the end. Its leather armor was strong, but it couldn't withstand many bullets, and the dozens of bullets fired by the Browning heavy machine gun hit the solid leather armor violently, and still succeeded in tearing it through their solid leather armor.

The sound of the explosion calmed down, and the fifth wave of mutant zombie beetles rushed in again, and I threw down a biochemical grenade on hand, and at this time, there was only the last biochemical grenade left in my hand, and Dong Xin'er no longer had a grenade.

On the street, there were still six mutated zombie beetles at this time, five ordinary ones that evolved at one time, and one that evolved again. When the store was quiet again, under the order of the mutant zombie beetle that had evolved again, the remaining five mutant zombie beetles screamed and rushed into the storefront.

I looked at the only one left in my hand, hesitated for a moment, I didn't use it for the time being, there was a big guy out there that had evolved again, if I used this last biochemical grenade now, when it rushed in, it would not be able to inflict fatal damage on it with these guns alone.

The same mutant zombie creature that has evolved again, the mutant zombie beetle that has evolved again is definitely the best in the same level, its attack is fierce, and its leather armor is strong, even if it is two mutant zombie rats that have evolved again, they can't fight it.

A Biochemical Grenade can't do much damage to it, but it can corrode its leather armor and weaken its defenses. As long as its defense is weakened to a certain extent, the heavy machine gun will have a way to deal with it.

"Sun Yalei, we've run out of grenades, it's up to you now." I picked up an automatic rifle from the ground and walked over to Sun Yalei's side and said to him.

At this time, the last five mutant zombie beetles had already rushed to the front of the stairs, and Sun Yalei shouted loudly while controlling the Browning heavy machine gun shooting: "Boss, just look at it, I, Sun Yalei, am guarding the stairs with one gun and one shot, it is definitely a matter of one man, even if there are a few more mutant zombie beetles, they will never want to break through from me." ”

After listening to his bold words, I shook my head and smiled bitterly: "We need to save some bullets, even if I can conjure bullets for you, I'm afraid I won't have time to change the bullet chain." ”

"Da Da Da-"

On the first floor, there were already several mutated zombie beetles lying on the stairs at this time, these mutant zombie beetles were first torn off their armor by heavy machine guns, and then they were affected by corrosive gases, and they were already dying.

The last five mutant zombie beetles were piled up under this staircase at this time, and the narrow staircase restricted them, and they could only come one by one if they wanted to rush up, which also allowed the Browning heavy machine gun to concentrate its firepower.

No matter what time it is, there will only be one mutant zombie beetle in front of you, and there will definitely be no more. Sun Yalei only needs to point the heavy machine gun at the stairs and shoot frantically at a point.

"Da Da Da-"

The fire of the mutant zombie beetle heavy machine gun at the front was fixed at the bottom of the stairs, and the companions behind it blocked its way back, and a large number of bullets were fired at its body, tearing the leather armor little by little, and finally messing up everything in its body.

The first mutant zombie beetle fell to the ground weakly under the heavy machine gun's heavy fire, and its strong body was already in pieces.

The second mutant zombie beetle didn't even glance at the fallen kind, screaming, throwing the dying kindred aside and running desperately towards the stairs.

I was on the second floor, watching the bullets on the bullet chain plummet at a terrifying rate, my face became more and more gloomy, and there were four intact first-time evolutionary mutant zombie beetles below, and behind these little guys there was the big guy who had evolved again, and the bullets for the heavy machine gun were not enough.

"Sun Yalei, don't fight, stop immediately." Thinking of the mutant zombie beetle that had evolved again, I shook my head and told Sun Yalei to stop shooting.

Sun Yalei, who was playing very well, looked at me beside me in confusion and asked, "Boss, why don't you fight?" Without the blockade of heavy machine guns, these mutant zombie beetles would have rushed up. ”

My brows furrowed, and I couldn't help but be verbose, and said, "There is a mutant zombie beetle that has evolved again, if we run out of bullets now, we won't be able to stop it when that big guy comes up." ”

"There are only four mutant zombie beetles left downstairs, and they can barely clean it up with automatic rifles, leaving the bullets from the heavy machine gun behind to deal with that big guy."

Sun Yalei let out an "oh" and stopped shooting, and the whole building immediately fell silent.

Without the fire blockade of the heavy machine guns, the mutant zombie beetle below the stairs was finally unhindered, screaming, rushing up the stairs and towards the second floor.

I gripped the automatic rifle in both hands, aimed at the mutated zombie beetle at the front of the stairs, and gently pulled the trigger.

"Bang" A bullet jumped out of the chamber of the gun, wrapped in gray energy, and drew an arc in the air, whistling towards the head of the mutant zombie beetle a few steps away.

"Whoosh" Under the gaze of several people, the bullet accurately shot at the head of the mutant zombie beetle, and the powerful force broke through the layer of leather armor that was much stronger than the helmet, and successfully penetrated the head of the mutant zombie beetle.

"Tss

"Bang" was another loud gunshot, and the second mutant zombie beetle stepped over the corpse of its companion, and just after three steps, it was pierced by bullets in its head, and after some struggle, it collapsed on the stairs.

Watching the last mutant zombie beetle fall to the ground, a few of us finally let out a small breath.
