Within the base, Qin Yan walked expressionless.

He has understood the structure of the base. The whole base is divided into four layers.

The lower three floors are the experimental area, and the upper floor is the living area. Now Qin Yan is on the fourth floor.

As long as he kills all the way up, he will be able to destroy the whole base.

All the security personnel and researchers, Qin Yan, are not going to let go. They must be killed.

Now on the fourth floor, a team of security personnel and more than 20 researchers have been killed, and Qin Yan is about to enter the penultimate floor.

"Lord Qin Yan, there are several living practitioners."

Xie Dongguang's voice came. He just checked several cells by the way.

Pidongqiu glanced at his mouth. He didn't want to meddle in this business.

"Don't worry about them for the time being. When I kill all the people in this base, I'll come back and save them out." Qin Yan said faintly, "now you follow me to the next floor and help me collect their research data. I'll keep it useful."

"Yes, Lord Qin Yan."

They said at the same time and immediately began to act.

On the penultimate floor, Qin Yan saw 60 or 70 fully armed security personnel as soon as he went up, and the front security personnel were equipped with guns and grenades.

The so-called gun grenade is actually a kind of super caliber ammunition hung in front of the barrel and fired with guns and bullets. It can be divided into killing type and anti armour type, with great power.

"Kill him!"

"Shoot!"

Merck's voice came, and many security personnel fired at the same time.

The grenade shot at Qin Yan and burst out with terrible power. The whole base seemed to tremble.

The alloy door with a thickness of tens of millimeters is directly crushed under the bombardment of this degree.

"Dead?"

"He can't stop such a dense attack!"

But the smoke and dust dispersed, and a group of security personnel were stunned. What did they see.

Qin Yan stood there without breaking his clothes. What happened just now.

"Die!"

Qin Yan rushed in a flash, and his speed reached the point close to the sound speed.

A distance of 100 meters doesn't take a second at all.

The powerful speed brought up the terrible vigorous wind and smashed these security personnel in an instant.

Qin Yan went behind a group of security personnel. At this time, the bodies all over the sky fell down. At the same time, a lot of blood stained the walls and ground red.

"Impossible!"

"Is this still human? The speed is almost close to the speed of sound."

In the base monitoring room, several people were silent.

Elaine slumped on the ground: "impossible, impossible, according to our research, humans can't be so powerful."

Merck was silent: "this is just the cultivator of the true Dan realm. There are also the strong ones of the true divine realm and even higher realm."

Elaine clenched her fist: "it's not in line with science. I found... I found that our research is still at the lowest stage. There are many things that can't be explained by science."

Merck was helpless. He continued to look at the monitoring, but found that Qin Yan was no longer on the penultimate floor.

On the penultimate floor, more than 70 security personnel and more than 40 researchers have all been killed.

Up to now, 100 security personnel and more than 70 researchers have died.

"Captain, the man has reached the penultimate floor, that is, the floor next to the living area. According to this speed, he will soon reach the living area."

"Have the laser weapons and bombs been placed?"

"It's all ready. We'll kill him at all costs."

On the penultimate floor, Qin Yan carried his hands on his back and his hair danced in the wind.

More than 30 security personnel hid around and aimed at him.

"Attack!"

"Start the bomb and prepare the laser weapons!"

Qin Yan snorted coldly, but he was' whoosh 'and disappeared. All the bombs didn't even hit his clothes.

"Where is he?"

"In..."

Before his words were finished, Qin Yan punched out, the laboratory collapsed directly, and several security personnel and researchers died on the spot.

"Die, devil!"

The laser weapon shoots at Qin Yan. Qin Yan doesn't even avoid it.

The laser weapon sent out a ray of light on his arm, and suddenly his eyebrow frowned.

"What's going on?"

"He hesitated, attack him!"

Suddenly, dozens of laser weapons were launched at the same time.

Qin Yan sneered at this time and roared directly. The huge sound wave spread out. These security personnel immediately felt that their ears were torn and immediately fell to the ground and rolled up.

Blood flowed out of their ears and eyes, which was terrible.

Qin Yan looked down at his arm. There was a black spot on it. It was the place just irradiated by the laser weapon.

"It's incredible that you can hurt me."

Qin Yan murmured and continued to walk towards the next floor, but he walked step by step. Those screaming security personnel turned into meat pieces one after another, just like red plum blossoming.

"Devil, this man is definitely a devil!"

Dr. Elaine was pale and his hands were shaking.

The same is true of others.

"He's coming up. There are so many scientists in the living area."

"There's no time. Evacuate immediately."

"Captain..."

This means that they will abandon all the researchers in their living area, and there are more than 300 people.

Qin Yan has come to this level, and many researchers are fleeing in a hurry.

"Kill!"

Qin Yan grabbed a scalpel, one by one, mercilessly.

"You can't kill me. The U.S. government asked me to do so."

"Devil, you are a devil. I'll go out and sue you."

"Let me go. I'm forced."

Screams continued, and a minute later, the world was completely quiet.

Qin Yan looked at the elevator at this time. Now the elevator has reached the top. Someone left here.

He tried to press the button to get off the elevator, but the elevator didn't come down at all.

Qin Yan snorted coldly, but his hands directly tore the elevator door, and then flew up along the elevator shaft.

Boom.

The elevator was blown to the sky dozens of meters high by Qin Yan, and Qin Yan also returned to the ground.

In front of us, three helicopters are slowly taking off, carrying Dr. Elaine and the remaining security personnel.

Qin Yan didn't rush to start, but entered the nearby military car. His long gun was still inside.

With a slight twist, the gun head poked out.

The whole long gun has more than two meters, which is just suitable for Qin Yan.

"It's more than 300 meters from the ground. Shouldn't he come up?"

"Damn, it's really hateful. Our research for so many years was destroyed in such a way."

When a group of people felt out of danger, they only saw a red light rising into the sky, like a rainbow through the sun.

In an instant, everyone's face changed greatly.
