Wang Xiaohai grabbed the groove in front of the steel door and pulled it to the side. There was another long corridor in front.
Footsteps were heard and a team of armed security personnel rushed out from around the corner.
Seeing the gun pointed at him, Wang Xiaohai immediately closed the steel door.
"Ding ding ding ding..." Bullets poured on the door, sparks flying, but the steel door was still very hard and thick, and the ordinary rifles of these security guards could not penetrate it!
Feeling the vibration coming from behind the door, Wang Xiaohai said, "I'll count to three and then I'll open the steel door. The three of you, get ready and load your guns."
Cheng Yan and the twins nodded in understanding.
"Three, two, one, here I come!" Wang Xiaohai said, and suddenly opened the steel door.
Cheng Yan and the twins opened fire immediately, and the bullets instantly passed through the gaps in the door and shot towards the security personnel.
After hearing a few muffled groans from the front, Wang Xiaohai closed the door again, and the steel door was once again bombarded with bullets like rain.
After waiting for more than ten seconds, the sound of bullets from the opposite side quieted down. Wang Xiaohai opened the steel door again to allow Cheng Yan and others to launch a sneak attack for one second, and then closed it again.
This cycle repeated several times, and most of the enemies on the opposite side fell. The remaining few fled in panic and no longer held their ground.
Wang Xiaohai opened the steel door completely, and the four of them walked forward slowly and cautiously.
The four of them searched the fallen enemies for bullets, and the twin brothers also switched to rifles. Finally reaching the end of the corner, it seemed there was no danger, and Cheng Yan's tense nerves suddenly relaxed a little.
"Be careful!" Wang Xiaohai shouted, pushed Cheng Yan away, and then lay down.
As soon as Cheng Yan fell to the ground, he heard a loud explosion. Iron pieces and blood brushed past his head, almost killing him!
"I didn't expect that they would install contact mines on the bodies of our companions," said Wang Xiaohai.
"Thank you for saving my life. I shouldn't let my guard down," Cheng Yan said. "There are dangers everywhere here. I should stay alert and be extremely careful!"
Having said that, it is impossible for people’s nerves to be tense all the time, and there will be times when they feel tired.
The four of them left the corridor and turned right. In front of them was a wide hall, half the size of a football field, filled with densely packed biochemical transparent nutrient capsules and sophisticated experimental instruments. There were many staff members busy next to the instruments. They were not panicked when they saw Wang Xiaohai and the other three come in, but continued to be busy with their own things.
Wang Xiaohai walked over to a middle-aged experimenter in a white coat and asked, "Why didn't you run away when you saw us coming in?"
"Run? Where can we run to!" The experimenter turned to face Wang Xiaohai and said, "We were also captured. We are equivalent to slaves, not bad people. If you want to find the armed men of the Bullet Group, just keep walking straight ahead." The experimenter pointed to the passage at the end of the hall behind him.
"What experiment are you doing?" Wang Xiaohai asked curiously.
"Do you want to know?" the researcher said, "We also do experiments on human biochemistry and dangerous organisms. We mainly create cyborgs and implant chips to control dangerous organisms."
Cheng Yan, who was standing behind Wang Xiaohai, felt a chill down his spine. He pointed at the creature in the cylindrical transparent nutrient chamber and stammered, "Could it be that one of our classmates is in there?"
"No, this is a previous experimental subject. They didn't send the latest experimental subject here. It is probably being held somewhere on the lower level." The experimenter replied.
It turned out that the students were locked up on the next floor.
"What are dangerous creatures?" Cheng Yan asked.
"I don't know about that. They were all shipped here in large sealed containers. Didn't you hear the roar?" the experimenter replied.
First, they went to rescue the imprisoned students, and the four of them walked towards the passage at the back of the hall.
