This sudden sound was like a thunderclap, exploding in Gao Qiang's ears, causing his originally calm face under the mask to change instantly.
He knew very well what kind of secrets and dangers were hidden in this corridor. To be able to release those things so quickly to resist the enemy, the enemy must be extremely fierce.
But these things are not what he needs to worry about now. The most urgent task is to take people to see the supervisor as soon as possible.
"Bang bang bang! Bang bang bang!" A burst of dense and intense gunfire suddenly rang out, hitting the entrance of the corridor like raindrops. At the same time, "Da da da! Da da da da da!" Another burst of rapid shooting sounds intertwined with it, forming a deafening hail of bullets.
Not far from the entrance to the corridor, some guards of the base were fighting desperately. They cleverly used the geographical advantage of the corner position, pressed their bodies against the wall, and the guns in their hands continued to spray flames.
Since the road at the beginning of the corridor was narrow and easy to defend but difficult to attack, this posed a great obstacle to the attacking side. Chen Bufan's soldiers were forced to engage in a thrilling street battle with the tenacious guards.
They tried to force their way through the defense line, but each step forward seemed extremely difficult. Although the enemy's shooting skills were not very good, just verbally seeking death in such a place was tantamount to seeking death.
To successfully break through here, one must either rely on powerful heavy firepower to suppress the enemy, or adopt human wave tactics and crush them with absolute advantage in numbers, but this will inevitably cause a large number of casualties.
At this time, Chen Bufan's soldiers who were responsible for the attack at the front were in a very difficult situation. The grenades they carried had long been used up, and facing the tight defense of the guards, it was difficult to make a breakthrough for a while.
In desperation, they could only stop temporarily, confronting the guards in a tense manner while waiting for logistical support from the rear. Because there was only one entrance, the transportation of ammunition was very slow.
Just as the two sides were confronting each other, screams suddenly began to emanate from the soldiers guarding the base, and the rain of bullets from there no longer poured down on Chen Bufan's soldiers.
"Ahhhh! Ahhhhhh!"
From time to time, bursts of screams and roars could be heard from the corridor. Some soldiers were seriously injured and fell in a pool of blood, while others were hit in the vitals by their own bullets and died on the spot. The sounds of eating meat could also be heard among them.
"No! No!"
“Asshole!! Aaaaaahhh!”
“Why would they do that!”
"We're still here! Damn it!"
"Da-da-da-da! KA-KA!"
"I'm out of bullets!"
"We have been abandoned, we have been betrayed!"
Shouts of fear rose one after another, echoing throughout the entire corridor. The soldiers on Chen Bufan's side looked at each other, not knowing what was happening inside. They were at least a hundred meters away from the corner in front, and the sound came from the corner, so they couldn't see it.
Not long after, the other side gradually became quiet, and no more sound was heard.
There were only a few guards left who were originally responsible for the defense. If it weren't for the favorable terrain conditions, the confrontation would have ended long ago.
At this time, in the control center, Zhang Jingyuan stared at the surveillance screen with a cold expression.
Seeing his guards being brutally eaten one by one by those horrible zombies, he felt no wave of emotion at all. If he had to express some emotion, it would be a hint of satisfaction at the powerful abilities of these zombies.
These zombies are not ordinary monsters, they are all the products of failed laboratory research.
Due to their large number, they have been hidden in these deep corridors and secret rooms.
The location of this KTV is just a back door of a huge underground experimental base.
That is why these extremely dangerous failures are placed here.
Who could have guessed that someone would choose to launch an attack from here?
Zhang Jingyuan slowly turned his head and looked at an assistant beside him with a sharp gaze. He asked expressionlessly, "Has the G3h1 strain arrived at the designated location?"
Hearing this, the deputy's face changed slightly, his expression became solemn, and after a slight hesitation, he replied:
"Professor Zhang, the personnel we sent out set off the day before yesterday.
According to normal calculations, if everything goes well, we should be able to arrive at the designated location on time.
However, the external situation is so unpredictable right now that it is difficult to know exactly what the actual situation is."
Zhang Jingyuan turned his head, his eyes showing a hint of madness, which gradually calmed down after a few seconds.
"Everything depends on God's will."
After saying that, he pressed another button on the panel.
Inside the entrance of the corridor, 100 meters away.
"In class, how about I go and take a look?"
"Wait, let's build a position here first, and then go over to see what's going on. If things get awkward, we can run back and use the position as cover."
"Yes! Hehe, why don't you be the squad leader? You always think comprehensively."
"Stop kissing my ass and get to work!"
The temporary position was very simple, made of sacks of soil, which had been prepared before going underground.
Commander An said that such a large biochemical laboratory must have very strict defenses.
In a short while, the simple position was completed, but there was no heavy machine gun, because the entrance was not large, and the troops were transported first. The heavy weapons were still to come, but they would be there soon.
"The only thing missing is the heavy machine gun. Let's make do with the light machine gun for now. Squad leader, I'm in?"
"Can……"
Before the squad leader of this team could agree, he heard light and dense footsteps behind him.
He looked back and immediately stood at attention and saluted.
An Ning walked over with a gun slung over her shoulder, followed by many soldiers carrying ammunition boxes.
"What's going on?" An Ning lowered her voice.
The squad leader gave a general account of the situation.
"Commander An, do you want to send someone to check it out?"
"Om..."
Before An Ning could answer, the lights in the corridor suddenly went out, and the surroundings suddenly went from bright as day to pitch black, and nothing could be seen.
The soldiers immediately raised their guns and began to be on guard.
An Ning looked across the corridor with sharp eyes, at the wall facing them at the fork in the road.
One camera still had a red light on, indicating it was working. Obviously, someone had deliberately turned off the light in order to make things more difficult for them.
The squad leader and several soldiers put on their night vision goggles and said, "Commander An, shall we go over and check it out?"
