Facing Haixin's inquiry, Li Yan was actually full of doubts in his heart.

According to Aunt Van Fan, the device is connected to the ventilation system, and if activated, the anesthetic will enter the laboratory through the ventilation hole, and then complete the anesthesia of everyone in the laboratory.

However, from the door of the cave laboratory, twelve killers of the Sword of Glory rushed out in one go, which was completely beyond the expectations of the two.

"I don't know, it stands to reason that it shouldn't."

Li Yan shook his head, he still had complete trust in Aunt Fan in his heart.

Aunt Fan's whole plan was perfect, and although there were a few minor flaws, it was not too late to make amends.

All known flaws have been repaired and filled.

Now, the most critical part of this is the release of anesthetics, and it seems that something has gone wrong.

"Ventilation systems usually don't work alone, they need to be powered to trigger ......"

Li Yan was thinking about possible problems in his mind, but while he was thinking, the first gunshot suddenly rang out at the entrance of the cave in the distance!

The battle between the Sword of Glory and the Yagi Priest kicked off with this gunshot.

Li Yan and Haixin quickly withdrew out of the range of the battle circle, this kind of dog-eat-dog-haired battle, just be a spectator.

"Brother Yan, if the device of the ventilation system is not successfully triggered, then I am afraid that the rest of the matter will be very troublesome."

Haixin's worries are very clear, Aunt Fan has spent so much effort to set up such a game, seeing that everything is going to end smoothly, but the most critical link has gone wrong.

"Don't worry, it's okay."

Li Yan shook his head, then pulled out his dragon killing blade, and then sneered and said, "I will kill them all one by one!" ”

Haixin was shocked by Li Yan's sudden outbreak of murderous intent, and broke out in a cold sweat.

She has long known that Li Yan is not an ordinary person, and she also knows that when he says that he will kill a target, he will definitely not just talk about it.

She was a little worried, as if the blood in Li Yan's eyes was slowly spreading in the rising sun.

It was a thirst for blood and death, hard to explain, but it was real!

Da Da!!

Haixin just wanted to take over Li Yan's words and say something to him, when suddenly a series of extremely rapid gunshots suddenly sounded in the direction of one o'clock in front of the right!

The bullet hit the hiding place where Li Yan and Haixin were.

The bullet tore the dirt and gravel above their heads to pieces.

Haixin was pressed in Li Yan's arms, so her position was lower, and the sudden attack of this round of bullets did not hit her.

But Li Yan was not so lucky.

A bullet shattered a fist-sized brittle stone.

The so-called brittle stone, in fact, is a type of obsidian, which is extremely hard in texture, but it is very brittle and can be easily destroyed.

The bullet shattered a small piece of obsidian, and a piece of rubble flew over Li Yan's cheek.

Clinging against his cheekbones, he almost cut his eyes open.

Even so, the sharp stone chip cut a shallow cut into the right side of his cheek.

For a while, the blood flowed like a pump!

The moment Haixin looked up and saw Li Yan injured, he couldn't help but be shocked in his heart.

"Li Yan, you're injured!"

When Hai Xin just wanted to check some of the wounds on Li Yan's face, he had already revealed a light in his eyes that made Hai Xin's heart faintly chill!

"Stay here!"

Li Yan threw down these four words, and then rushed out directly from the hiding place!

That's right, it's the kind of rushing out like a life!

The morning sun is rising, and the last rays of darkness before dawn are about to dissolve in the sun.

Li Yan's figure rushed out of the rock of the hiding place and rushed straight to the gunman with an AK47 assault rifle!

That set of strafing just now was a good thing he did!

Li Yan's tyrannical heart had suddenly risen, and the shuttle bullet, coupled with the wound on his face, had stimulated the already churning killing intent in his blood.

This time, it was surprising that the dragon's blood wood beads worn on his chest didn't emit any strange heat to dissolve the monstrous killing intent on Li Yan's chest!!

The gunman saw that Li Yan suddenly rushed out of his hiding place, holding a snow-white dagger in his hand, and rushed towards him like a sturdy cheetah!

The gunman was shocked for a moment, but soon turned into a hideous sneer, pushed a spare magazine full of bullets directly into the chamber of the gun, and pulled the trigger in the direction of Li Yan at the back end!!

Da Da!!

The bullet roared out of its chamber and went straight to Li Yan, who was moving at high speed!

Li Yan's figure was at the moment when the other party pulled the trigger, and the person had suddenly increased his speed and changed direction!

At least six bullets hit where he had been, and the bullets were still chasing him in the direction he had changed!!

The magazine capacity of the AK47 assault rifle is thirty rounds.

There are enough of them, and the bullets are powerful enough.

However, the AK gun has a world-renowned recoil force, and the moment the first bullet is fired, the gun will suddenly jump backwards, and the second and third bullets are barely within the control range.

However, starting with the fourth bullet, if the gunner's weight or strength is not enough, the bullet will fly directly into the sky.

The distance between the gunman and Li Yan was about fifty meters, and when the sun hit the rock, he saw as if someone was hiding there.

Plus, they've already engaged in a head-to-head shootout with the Sword of Glory.

Naturally, with a discovery, the easiest way is to shoot and greet it directly!

At a distance of fifty meters, the gunner felt more and more that this distance was the distance between him and death!

The bullets in his hand were still spraying, but Li Yan's figure was still lightning and suddenly changed direction left and right, with the help of this ubiquitous cover, the bullets in his magazine were consumed one by one!

The distance of fifty meters was quickly shortened to thirty meters in less than three seconds!

And it's getting shorter!

"Damn bastard!"

The gunman used up all the bullets in the assault rifle in one go, but he still couldn't kill Li Yan.

On the contrary, when he gave up the assault rifle and pulled out the pistol, Li Yan's figure had already rushed to within fifteen meters!

Fifteen meters, which is usually the best killing distance for a pistol.

But only if you can hit it!

Bang!!

The gunner was not slow to abandon the assault rifle and draw the pistol, and it was obvious that he was a trained professional!

At the very least, it's much more professional than the professional killers of the Sword of Glory who are better at assassination.

However, even then, when his gun had just pulled the trigger and fired the first bullet.

Li Yan's figure suddenly rushed to his front at an extremely strange angle and route.

The dragon slaying blade shimmered with a chilling light of death in the morning sun, and simply sliced the gunman's neck neatly!!
