Fighting in a matchbox-shaped, concrete-reinforced building at the Chida Medical Research Institute, the MP7 submachine gun, which has a high rate of fire, high accuracy, low ballistics, good penetration, and good penetration, has advantages over the HK416 automatic rifle.

Luo Hao pulled off the monocular night vision device fixed on the bulletproof helmet again, blocking it in front of his eyes, and suddenly the world in his left eye turned emerald green again.

"Click!"

Another blue-purple electric snake passed through the thick clouds in the sky, landed on the four lightning rods towering around the roof of the building, and disappeared in an instant.

"Whoa......

As soon as the lightning flashed, raindrops the size of beans fell through the clouds in the sky. Raindrops crackled as they hit the branches and leaves above the heads of the five members of Tactical Group B.

After Luo Hao asked Li Yifeng to find a sniper position on his own, he took the remaining three team members and continued to move towards the Chita Medical Research Institute outside the woods.

Li Yifeng untied the TAC-50 anti-materiel sniper rifle behind him, opened the front bracket, and placed it side by side with the Remington MSR sniper rifle in his hand, then pulled out the camouflage net stuffed in the tactical backpack and covered himself.

Although the distance from the Qiantian Medical Research Institute was getting closer and closer at this time, because of the sound of rain as a cover, Luo Hao, Zhou Bai, Situ Kong, and Lin Xiaoyang did not deliberately slow down the speed under their feet.

The sound of "rustling" footsteps and the "whooshing" sound of rain are mixed together, and it is difficult to distinguish even if they are only a few meters apart.

Because of the sudden thunderstorm, the snipers and sentries who were originally deployed on the roof of the medical research institute were withdrawn. This is definitely good news for Tactical Group B.

"Assault group, someone is approaching in your direction. Swimming sentry, three people, FNC automatic rifle. ”

When Luo Hao, Zhou Bai, Situ Kong, and Lin Xiaoyang were less than twenty meters away from the exit of the woods, Li Yifeng's reminder came from the headsets of the four people.

The four of them immediately slowed down their progress, bent their waists, and slowly approached in the direction of the exit of the woods.

When he was still five meters away from the woods, Luo Hao asked Lin Xiaoyang and Situ Kong to stay in place and keep guard, and he and Zhou Bai continued to approach the exit of the dense forest.

Luo Hao and Zhou Bai walked slowly to the edge of the rock in the dense forest, and glanced at the three sentinels under the rock.

Two of the three sentries in white hazmat suits, all equipped with FNC automatic rifles, were hiding under the rocks, taking off their gas masks and smoking, while the other was standing in the corner with his back to the two sentries smoking.

Luo Hao and Zhou Bai glanced at each other, threw the MP7 submachine gun behind him, and then took out the Alaska Whaling Fork Survival Knife and held it in his hand, and the raindrops hit the black body of the Alaska Whaling Fork Survival Knife, and immediately shattered into countless small water droplets, making the already cold saber a little colder.

"Whew!"

A bullet flew from Li Yifeng's hiding place and burrowed into the head of the sentry who was constantly shaking his body.

"Poof!"

A sound like a summer watermelon bursting came from the darkness. In the dark green night vision goggles, Luo Hao could clearly see the brains that had been stirred into a pulp by bullets, splashing out of the head of the sentry who hadn't even had time to put the "bird" into the crotch of his pants.

Seeing the companion who was suddenly sniped, the two sentries standing side by side were immediately shocked, threw away the cigarette that had just been lit in their hands and had not yet smoked a few puffs, picked up the FNC automatic rifle hanging on their shoulders, and planned to pull the trigger to warn.

However, the two sentries had just raised their guns, and before they even had time to pull the trigger on their fingers, Luo Hao and Zhou Bai had already jumped off the rocks, and the Alaskan whaling fork survival knife held in both hands pierced the back of the heads of the two sentinels and pierced each other's necks, and the sharp tip of the knife pierced through the sentry's jaw with warm blood, and the two sentries were killed on the spot.

Luo Hao used his knee to resist the sentry who was killed by himself, and pulled out the Alaskan whaling fork survival knife inserted in the neck of the sentry, and the blood beads on the knife body were instantly washed away by the pouring rain.

After putting the knife back in the scabbard, he and Zhou Bai held up the corpses on the ground, and with the cooperation of Situ Kong and Lin Xiaoyang, they threw the three corpses into the dense forest. It's too close to the Institute of Medicine, and if you leave the body here, you'll be found quickly.

After disposing of the three corpses, Situ Kong and Lin Xiaoyang also jumped off the rock, and the four of them continued to move in the direction of the Medical Research Institute under the cover of Li Yifeng.

After the two swimming sentinels passed, the four of them quickly approached the sunny side of the medical research institute.

The shade-loving plants near the barbed wire fence grew very luxuriantly, and the four of them slowly approached the barbed wire fence under the cover of these plants.

Because it was raining, the rainwater would conduct electricity and pose a danger to the nearby patrol officers, so the high-voltage electricity that was originally connected to the barbed wire had been cut off, which also directly facilitated Luo Hao's movements.

Luo Hao, Zhou Bai, and Situ Kong were on guard with guns, Lin Xiaoyang took off the big scissors behind his backpack, cut a small square hole in the barbed wire, patted Situ Kong's back, and then entered the medical research institute through the small hole first; Before passing through the small hole, Situ Kong patted Zhou Bai on the shoulder again, and so on, and the four of them passed through the small hole in turn and entered the medical research institute.

After Luo Hao entered the medical research institute, he reset the barbed wire cut by Lin Xiaoyang and fixed it with a thin iron wire.

After entering the Chida Medical Research Institute, the four people did not directly enter the medical research institute, and after avoiding the two groups of patrol officers, they followed the cover of darkness and quietly approached the mechanized infantry fighting vehicle, the reconnaissance and alert vehicle, and the three Humvee H1 jeeps parked in the open space.

If they are hindered during the retreat, these few tin monsters will be the biggest trouble. Especially that infantry fighting vehicle, a thirty-five mm cannon plus two anti-tank missile launchers, this power is definitely no joke!

The four of them scattered to install explosives on these vehicles, and Luo Hao had just loaded explosives under the reconnaissance and warning car, and drilled out from under the car, intending to pass the Humvee H1 jeep parked next to the reconnaissance and warning car, when a figure was projected onto the ground.

Immediately afterwards, a patrol officer muttered in ghost language that Luo Hao didn't understand, but could vaguely guess the meaning, and hurriedly ran towards the rear of the reconnaissance car.

Luo Hao's body was close to the reconnaissance car, raised his left foot, and slowly pulled out the Alaskan Whaling Fork Survival Knife from the scabbard tied to the outside of his left calf, and held it in his hand.
