The soldiers on the windows of the building kept firing at the bottom, and all kinds of weapons and ammunition were deployed by Zhang Zhixue from the military factory, Zhang Zhixue did not dare to underestimate such a huge number of corpses, so he had to do his best to hold his position, and he must not retreat back to the military factory until he had to.

Because once the troops are withdrawn to the military factory, although there is a last super strong iron gate to stop the zombies, making it impossible to enter no matter what method is used, but once they really retreat back to the military factory, the soldiers of the army are really at the end of the road.

If he was really trapped in the military factory by this incalculable number of corpses, within two months, all the soldiers would have to starve to death in the factory, so Zhang Zhixue could only choose to go all out, even if he used up all the ammunition in reserve, he had to eliminate the corpse tide outside the building, and he must not be trapped in the military factory, and then he would only have to wait for death.

Zhang Zhixue's hand holding the machine gun was slightly numb, and she could only pray that the existing ammunition of the troops could hold on until the last zombie was eliminated.

"Strange, what about Liu Yuyi? Slash these zombies with thunder! Liu Xing muttered to himself in confusion.

At the same time, in the underground parking lot of Tianbo Enterprise Building, which is full of white smoke virus, Liu Yuyi and Chen Yang's team are struggling to fight against the high-level zombies that sneaked into the parking lot.

Originally, Liu Yuyi was responsible for protecting Chen Yang's team, and drove the two tanks parked in the underground parking lot outside to destroy the zombies, but as soon as Liu Yuyi and others walked out of the gate of the military factory, they were ambushed by high-level zombies, and the white smoke virus that they encountered before reappeared, which immediately weakened Liu Yuyi's combat power to the limit.

Liu Yuyi, who had learned the lesson from the last time, hurriedly put on a gas mask, and worked hard with Chen Yang's team and others to close the gate of the military factory to prevent high-level zombies from rushing into the military factory.

The white smoke virus is getting denser and denser, and it is no longer possible to see anything clearly in the underground parking lot, Liu Yuyi can only vaguely identify the location of the zombies through his voice, and the sound of his comrades sacrificing is constantly heard in his ears.

"I didn't expect the other party to dare to come to the door!" Liu Yuyi thought anxiously in his heart, the screams of his comrades-in-arms reached his ears in an endless stream, and in this thick white smoke virus, Liu Yuyi's proud thunder and lightning ability could not play any role.

A third-order zombie sneaked away from behind Liu Yuyi, and when its claws just touched Liu Yuyi, Liu Yuyi turned around and pinched the neck of the third-order zombie, and then released a strong voltage, instantly turning the third-order zombie into a charred corpse, and then threw it on the ground, continuing to look for the direction out of the underground parking lot.

At this time, Liu Yuyi knew that he had no time to take care of Chen Yang and the others, and the most important thing he should do now was to quickly escape from the scope of the white smoke and quickly exert his due combat power in this battle.

"In this white smoke, as human beings, we can't see anything, but this group of zombies has a heat sense, and can know our exact location at all times, I hope Brother Chen Yang is fine!" Liu Yu muttered to himself.

Liu Yuyi groped his way forward in a white vast field of vision, and he was already a serious road idiot, but he was soon lost in the vast underground parking lot, and Liu Yuyi, who was anxious, stomped his feet.

"Made, how did I fall into this trap?" Liu Yuyi scolded angrily in his heart, and then continued to march forward.

Because there are many soldiers fighting in the upstairs building, Liu Yuyi didn't dare to blast a big hole directly above like last time, and then escape, now he can only choose to get out of this labyrinthine underground parking lot, just ask God to take care of him, and be able to get out as soon as possible.

On the roof of a taller building directly opposite the Tianbo Enterprise Building, Liu Xing used a sniper scope to investigate the battle situation, and finally found the white smoke slowly rising at the entrance of the underground parking lot of the building, and his heart was shocked.

"Could it be that Liu Yuyi is trapped in the parking lot?" Liu Xing frowned and muttered to himself.

The tide of corpses pouring into the direction of the military factory became more and more numerous, and soon the zombie group was already on the front foot and the back foot, densely packed and black to the downstairs of the building where Liu Xing and Li Dalong were.

Liu Xing didn't dare to shoot rashly to help the soldiers of the military factory more than a thousand meters away for the time being, because once he shot, the zombies under the building would soon pour up, and it would be even more troublesome at that time, so Liu Xing would not shoot easily unless he had to.

Looking at the billowing white smoke coming out of the entrance of the underground parking lot, Liu Xing always felt that this matter was not so simple, if Liu Yuyi was really trapped in the underground parking lot, then how did the other party guess that Liu Yuyi would appear in the underground parking lot?

On the Tianbo Enterprise Building, Zhang Zhixue really couldn't bear the pain from his hands, and if he continued to shoot like this, the machine gun that could not be cooled down would explode sooner or later, in desperation, Zhang Zhixue could only choose to take a break, cool down the machine gun, and hurriedly let another soldier set up a new machine gun to continue to suppress the zombie tide on the road.

"What's going on with this Liu Yuyi, why hasn't the tank been driven yet?" Zhang Zhixue muttered to herself anxiously and angrily.

Because of the particularity of the Tianbo Enterprise Building and the military factory, there is a separate elevator in the military factory, which can go straight to any floor of the building.

Zhang Zhixue just wanted to go to the parking lot to see what was going on, a soldier who took the elevator upstairs hurriedly ran to the rooftop and reported to Zhang Zhixue: "Sister Xue, it's not good, Chen Yang's team was ambushed and trapped in the underground parking lot, Liu Yuyi didn't know what was going on, and he couldn't exert the power of his ability, and now the underground parking lot is full of rich white smoke full of viruses and countless high-level zombies!" ”

"What? Liu Yuyi and they were ambushed? How so! Zhang Zhixue was furious, and hurriedly rushed downstairs and took the elevator to the military factory.

During the time when the elevator was descending, Zhang Zhixue quickly sorted out his thoughts in his mind, this corpse tide battle was obviously organized by the mastermind behind the scenes, and it was inferred from the white smoke virus in the underground parking lot that this person was the person who killed the Thor team before, Zhang Zhixue had just sent someone to retaliate and went back not long ago, but he didn't expect the other party to come to the door so quickly.

However, what is strange is that even if the other party came to the door to retaliate, how could he be so large-scale and planned, and actually learned that Liu Yuyi had recovered the news of his thunder and lightning ability, and he also happened to ambush Liu Yuyi and others in the underground parking lot, successfully limiting the maximum combat power of the troops to the underground parking lot?

The incalculable zombie group outside the building, the white smoke virus and high-level zombies ambushed in the underground parking lot in advance, all of this is too strange, and the other party seems to know the battle situation of their own side in advance.

Could it be that there is a traitor in the troops?
