Luo Hao, Zhou Bai, and Situ Kong untied the bag behind them, and took out the mines, explosives, and cluster gre......nades that were placed inside, as long as they could kill people, all the things that could kill people.

Luo Hao and Zhou Bai were in charge of mine-laying, and they were very fast, and they did not carefully camouflage the mines at all.

The "Broadcut" anti-infantry mine is erected at the corner of the test bench table, facing the direction of the personnel in an arc, and the remote control initiation device is directly installed in the electric fuse room; Trip-type anti-infantry mines, fixed directly at the exits of two tunnels.

When Luo Hao and Zhou Bobray were around, Situ Kong ran to the elevator, searched those armed guards, brought a few AUG-A1 automatic rifles, a few magazines and grenades, and put them behind the central test bench.

By the time Luo Hao and Zhou Bo finished the thunder and returned to the central test bench, the reinforcements had already gotten off the train and were rushing towards the underground laboratory, judging from the number of people, there were at least more than a hundred people!

The reinforcements of more than 100 people, except for Lin Xiaoyang, who was implanting a virus into the computer, Luo Hao, Situ Kong, and Zhou Bai, each of them had to kill an average of 40 people, and it was not ruled out that Inoue Oka would continue to send reinforcements!

Zhou Bai collected all the cluster grenades on the four people, and screwed two expansion modules under each base module.

Luo Hao glanced at a few cluster grenades that Zhou Bai had placed on the ground, and said, "When you use it for a while, leave one of these things!" ”

Zhou Bai was stunned for a moment when he heard this, then nodded, picked up one of the cluster grenades and put it behind him.

This cluster grenade was left behind for the four of them to use at the last minute, but even if they were forced to use this cluster grenade, they would have to pull a few more at the end.

Luo Hao took HK416, squatted behind the central test bench, stared around vigilantly, and asked Lin Xiaoyang: "Hummingbird, how is the situation over there?" ”

"The firewall is a bit tricky, maybe a few minutes longer than expected!" Lin Xiaoyang replied while nervously operating the PDA.

"You just implant the virus into the computer, and then destroy the biological vaccine, no matter how much time it takes, we will definitely win it!"

Luo Hao suddenly raised the HK416 in his hand, shot a long shot at several reinforcements who appeared in the circular corridor on the second floor, and shouted at Zhou Bai and Situ Kong beside him: "Pick up the enemy on the left!" ”

"Da Da Da ......"

Zhou Bai also used the automatic rifle in his hand to shoot a long point shot, which appeared in the circular corridor on the right, and the reinforcement enemy composed of the "undead" special service squad and ordinary armed personnel suppressed back.

The reinforcements in the circular corridor on the second floor immediately occupied the commanding heights and attacked Luo Hao and others around the central test bench.

The bullets fired by both sides rubbed the air between the central test bench and the circular corridor on the second floor. The bullets staggered through the air, and occasionally a few bullets happened to collide in mid-air, blending together into a small lump of copper-lead mixed metal, which fell to the ground.

"Phew!"

A bullet hit the central test bench, changing the trajectory of the ballistic trajectory to form a ricochet, which hit Lin Xiaoyang's right arm.

Lin Xiaoyang snorted in his mouth, and his right hand, which was operating the PDA, paused for a moment, but only after this moment's pause, Lin Xiaoyang continued to operate on the PDA, without even looking at the wound on his arm, let alone bandaging it, allowing the blood in his body to flow out of the opening and drip to the ground.

Lin Xiaoyang knows very well that every minute he consumes now is fought by Luo Hao, Zhou Bai, and Situ Kong, so it must not be wasted!

Lin Xiaoyang focused all his attention on the process of implanting a virus into the computer, forcing himself to ignore the pain in his arm.

Ten minutes later, when Lin Xiaoyang finished implanting the virus into the computer, a small pool of blood had gathered at his feet.

Lin Xiaoyang tore off the magic sticky strip on his left wrist, took off his PDA and put it on the ground, and said to Luo Hao: "The virus implantation is complete, but it will take five minutes for the invasion!" ”

Luo Hao nodded and asked, "How about the injury on your hand?" ”

Lin Xiaoyang glanced at the hole in his arm that was plowed out by the ricochet, and said, "The skin is traumatic, and the warhead is not in the muscle." ”

Lin Xiaoyang took out the first-aid kit from his backpack, took out the hemostatic powder, elastic hemostatic bandage, tore open the packaging bag of the hemostatic powder with his mouth, poured all the hemostatic powder inside on the wound, and then pulled one end of the hemostatic bandage with his left hand, pulled the other end with his mouth, and tied a knot after a few simple circles on his arm.

The hemostatic powder used by Lin Xiaoyang has a certain labor pain effect, and after sprinkling the hemostatic powder, the original hot pain of the wound was immediately alleviated, and he picked up the HK416 hanging on his body and joined the battle!

The enemy in the circular corridor on the second floor, seeing that he could not attack for a long time, suddenly became a little anxious, and several armed guards wearing navy blue combat uniforms and wearing only two eyes and mouths were exposed, took off the grenade hanging on the tactical vest, pulled the pull ring, and threw it down from the corridor.

Seeing the grenade falling from the upstairs in a free-fall motion, Luo Hao's eyes tightened suddenly, and he pressed Lin Xiaoyang to the ground, dodging the grenade fragments flying everywhere.

Luo Hao shook his head, relieved the impact of the explosion sound wave on his eardrums, and said to Zhou Bai: "The back attack is not good for us, our grenades can't be thrown, find a way to let them come down!" If they bombard them with grenades and grenades, we'll all finish the ball! ”

As soon as Luo Hao's words fell, another steel ball grenade was thrown down from the circular corridor on the second floor, and the landing point of this grenade happened to be the central test bench where Luo Hao and the others were!

The time-delay fuse of the grenade is generally between three and five seconds, and the time to remove the grenade falling in the air is removed, as long as the grenade lands, there is almost no extra time for the four people around the central test bench to throw the grenade out!

"Dada......"

Seeing that the four of them were about to be killed by such a grenade, Situ Kong suddenly became ruthless, picked up the SAW light machine gun in his hand, pulled the trigger to the end, and fired wildly at the grenade in mid-air.

Every muscle and hair in Situ Kong's body trembled from his frantic strafing, and hot bullet casings and fragments of broken plastic bullet chains fell at his feet.

An airtight rain of bullets composed of dense warheads shrouded towards the grenade, which was still in free fall in mid-air.
