There were many corpses lying around, and among them were a few soldiers. There were also dozens of heavily armed men in desert camouflage clothing patrolling the area.

In the underground center of the research facility, more than twenty researchers wearing white coats were gathered together. They were all squatting on the floor.

A forty year old Bald Black sat on the research table with a lazy expression. He spoke to the people squatting on the ground in a foreign language, "Hurry up and hand over the research materials. Don't waste any more of my time here."

"Save it, even if we die, we won't give you the information." The leader, a white-haired old man, spoke in a low voice.

"Very well, let's see how long you can continue being so stubborn for." Bald Black took out his gun.

Peng, it struck the head of a man beside the old man. That man immediately fell into a pool of blood and lost his life.

"Little Zhang!" The old man shouted and stood up abruptly. "If you have the ability, then kill me!"

"I'm not going to kill you. If you don't cooperate, I'll kill them all!" Bald Black waved his hand, and the mercenaries around all raised their spears.

"We are not afraid of death, kill us if you dare!" The others also stood up.

Seeing that, the Bald Black's gaze sank. He could kill one person, but could not kill everyone. If he could not get what he wanted, then this trip would have been in vain.

"Let them calm down!" The Bald Black shouted.

After hearing the order, the mercenaries stepped forward and knocked everyone to the ground with their fists or the butts of their spears.

"Boss, there's a plane outside!" A voice came from the Bald Black's earpiece. It was detected by the sniper hiding upstairs.

The Bald Black sneered and said to the mercenaries around him: "Keep your spirits up, the Chinese military is sending people over again."

"Yes sir!" The surrounding mercenaries all revealed smiles on their faces.

This was because they had already forced back several batches of China's special forces, so they believed that it would be the same this time.

"Executioners, you will all die here!" The old man wiped the blood off his face and said bitterly.

"That will depend on who has the ability to do so." The Bald Black laughed.

Just as he finished his sentence, a gunshot was heard from outside and there was no further movement.

"What's going on?" Bald Black frowned, then used his earphones to call the sniper outside.

However, after calling for a long time, no one answered.

On the helicopter, Shen Feng looked at the body of the sniper through the aiming lens of his sniper rifle and sneered: "You think that you will be okay if you hide behind the wall?"

Because it was an offensive and defensive battle, Shen Feng deliberately chose to use large caliber anti-sniper rifles, and it was matched with armor piercing bullets, so normal walls would not be able to block it.

At this moment, all of the Xuan Group members on the helicopter saw this, Shen Feng's shot had indeed shocked them.

Due to the gunshot just now, it had broken the tranquility of the island. All the mercenaries in the research facility had become cautious.

"Get off the plane!" The A team leader, Fan Yunhai, gave the order, and all the A team members quickly disembarked from the plane, moving towards the back of the research facility.

"Bam!" With a sound, Shen Feng pulled the trigger again, the bullet pierced through the window and even penetrated through a wall in the research facility's room, directly killing a mercenary on the spot.

The mercenaries were also experienced in battle, and when they saw their comrades were killed, they shouted, "Armor Piercing Bombs! They have armor piercing bullets! "

After that, they all hid behind some of the thicker walls, and no one dared to show their faces.

"Very well, they have become cowards. All of you, go ahead. I'll show you all." Shen Feng said to the other members of the B Group.

"Attack!" With Chu Kun's order, other than Shen Feng, the other members of Group B quickly climbed the rope ladder down.

Having learnt their lesson, the mercenaries became more intelligent and started to move around in the dark.

Shen Feng, on the other hand, was observing the interior of the building through the scope of the scope. He looked at the dead bodies of the guards on the ground, and the Chinese soldiers, his eyes revealing a glimmer of light.

At this moment, the other members of Group B had already started using different methods to infiltrate the building, and the sounds of gunfire could be heard from their surroundings.

"Fly upstairs, I want to go straight down." Shen Feng said to the helicopter pilot.

"No, it's too dangerous." The pilot of the helicopter said.

"Even though I'm a newcomer, you still have to trust me."

"Fine." The helicopter pilot hesitated for a moment before replying and flying upstairs.

Carrying his sniper rifle, Shen Feng went straight to the top of the building, came up to the sniper he killed and picked up his communication device.

Bald Black, who was in the middle of thinking about a strategic plan and giving orders to the mercenaries, heard a cold and foreign voice from his earphones, "If you dare invade our territory, you better be prepared to die!"

"FUCK." The Bald Black scolded, but there was no sound coming from his headphones.

The one who spoke was Shen Feng. After he finished speaking, he carried his assault rifle and rushed downstairs with an extremely fast speed.

"Bam!" With a sound, Shen Feng kicked the door open.

The Type 95 assault rifle in his hand released an angry roar, the bullets carried Shen Feng's anger as it shot towards the six mercenaries inside the room.

Two of the mercenaries were killed by the bullets before they could even react.

The remaining four mercenaries quickly found cover.

Shen Feng saw that the other party was hiding behind his cover, and quickly pulled out the large caliber anti-sniper rifle on his back.

"Bam!" The armor piercing bullet pierced through the cover and killed a mercenary behind him on the spot.

This kind of large-caliber anti-sniper rifle change was very slow, so Shen Feng's figure sank, and quickly rushed towards the hiding place of the mercenary who was the closest to him.

Just as the mercenary was holding onto a spear and was about to come out from hiding to attack Shen Feng, Shen Feng had already arrived in front of him.

The mercenary's reaction speed was also very fast. He did not hesitate to pull the trigger.

He was fast, Shen Feng was faster!

Shen Feng extended his right hand out like lightning and grabbed the barrel of the gun, pressing it down fiercely.

"Ta ta ta …" All the bullets hit the ground.

After that, Shen Feng's left hand touched the dagger and waved fiercely.

"Die!" Shen Feng growled. A cold light flashed and a streak of blood appeared around the mercenary's neck.

Although Shen Feng was armed with a gun, his movements were fluid and without any hesitation.

After killing the mercenary, Shen Feng moved to the back of the cover, because the remaining two mercenaries in the room were already shooting towards him.
