Haixin's figure was hidden in the distance, witnessing the whole process of Li Yan killing all the Yaqi priests, and her reaction throughout the whole process was only one expression, sluggish!

One person killed more than two dozen heavily armed professional gunners, still with cold weapons.

She's only seen this kind of thing in movies.

Haixin didn't care about being in a daze, because Li Yan had already raised his hand high, greeting her from afar, and asked her to follow.

Haixin suddenly woke up from her distraction as if she was in another world, she hurriedly came out from behind the bunker where she was hiding, looked at the gun she was holding in her hand, and she was thinking about whether the gun in her hand was still useful.

But time waits for no one, and before Haixin thinks too much about anything, Li Yan's figure has already walked into the cave laboratory.

Haixin hurriedly put aside all the nonsense in his mind, focused on what was in front of him, and quickly followed.

When Haixin walked into the cave laboratory, he found that Li Yan hadn't actually gone too deep, because he was checking the ventilation holes around him.

"Li Yan, how's it going?"

Haixin came to Li Yan's approach and looked around vigilantly.

They hadn't forgotten that they had turned on the anesthetic gas dispensing device in the ventilation system before, and the light outside was already on, indicating that the device should have been activated.

Caution can often make people farther away from death at this time.

In the face of Haixin's inquiry, Li Yan immediately replied softly: "There are no toxic gases in the air, at least, there are no in this laboratory, all the ventilation holes are normal." ”

"So that means that the device didn't start for some reason?"

Haixin didn't know the specific situation, but she could make a reasonable inference from the situation in front of her.

"That's how it should be."

Li Yan nodded, and then changed his words: "But we can't take it lightly, there should be something that can be used here, don't lift a stone to shoot yourself in the foot." ”

As Li Yan spoke, he searched around the laboratory.

Although the laboratory is just for show, it is absolutely equipped with all the equipment it should have, including some gas masks to deal with high-risk emergencies and so on.

Soon, Li Yan and Haixin found a set of protective clothing.

This thing is a clothing with strong fire, water, and radiation protection functions, and of course, the point is that the protective suit has a matching gas mask.

Naturally, the two people will not wear protective clothing, but they still have to wear gas masks.

The human body is a powerful but fragile organism, and it is most susceptible to disintegration from the inside, so it is not possible to take risks if conditions permit.

Li Yan checked the gas mask and found that this mask was not what it looked like, it was a genuine gas mask with a high filtration grade.

"Follow me."

Li Yan put on his gas mask, and then walked towards the passage on the second basement floor.

Although wearing a gas mask can effectively prevent inhaling anesthetics and turning himself to the ground, it also hinders his vision to a certain extent.

Before Li Yan entered the passage on the second floor, he saw the alloy mechanical door that was twisted and broken due to the violent explosion.

On the door frame of the alloy mechanical door, a crack was created by the explosion.

The rift is arm-wide and narrow, in the shape of lightning, extending outward from thick to thin.

Li Yan traced the rift, and finally saw a picture that he least wanted to see.

The crack was deeply embedded in the wall, and it seemed to be heading towards a vent.

Haixin also discovered the existence of this rift, and she, like Li Yan, instinctively tracked the direction and veins of the rift's eyes.

Eventually, the two looked at each other, and they both saw the confusion in each other's eyes.

There is no doubt that if the anesthetic gas release device really failed to activate for some reason, then this crack may be related to this crack.

"Li Yan, what should I do?"

Haixin can't make a sound, but he can ask with gestures.

"You stay here, as long as the person who comes out is not me, shoot him!"

Li Yan took off his gas mask, and since it was determined that the starting device of the anesthetic gas failed to start, it means that everything inside was safe.

The gas mask is too obstructive to vision, and it can be more comfortable to take off.

"You're going in alone?"

Haixin blurted out his doubts.

It's just that as soon as this sentence came out, she immediately realized that she was purely asking a superfluous question.

What Li Yan can do is completely beyond her imagination.

It's definitely the best choice to go in alone.

She followed up, and if she didn't do it, she might be holding back.

Speaking of such a thing as dragging his feet, Haixin has grown so big, he has been a policeman for so many years, and he has investigated countless murders and serious cases, and there are countless felons who have been captured and killed by his own hands.

But she never imagined that one day she would have the idea that she would drag others back.

"Take my word to heart and stay in this blind spot."

Li Yan smiled, and then pointed out a visual blind spot to Haixin, someone came out of the passage, and the position would definitely be ignored at the first time.

Haixin looked at the location, with her years of experience, it was definitely a good place for an ambush.

"Okay, be careful!"

Haixin nodded, checked the number of bullets in the pistol again, and then watched Li Yan leave, and he hid himself in the blind spot.

Although Li Yan's figure took off the gas mask, he did not throw it away, but pinned it directly behind his buttocks.

Although wearing this thing will block the view, if there is an emergency, it will also save people's lives.

Because it was not the first time for Li Yan to enter the basement floor of the laboratory, he was basically familiar with the road.

Soon, when he quietly entered through the passage, he saw the spider planting a bomb in front of the false door!

It seems that there is a loss of patience and wants to brute force it directly!

However, in addition to the spider and the snake tossing in front of the Nayama gate, someone is also alerting the surrounding situation.

Those four people were specially left behind by the ghost knife to do rough work.

After all, according to his idea, if the laboratory test samples were really hidden in it, the number of samples would be a difficult number to estimate.

A few more people to carry the samples will also allow the work to be done more efficiently.

It's just that the ghost knife has overlooked one thing, and that is that the battle outside seems to have stopped.

Moreover, all his thoughts were on the door in front of him, ignoring the people outside, and he hadn't reported the battle news to him for a long time.

"Boss, everything is ready!"

The spider was already in a cold sweat, the time it took to toss this door far exceeded his initial expectations, if he didn't get it done this time, the ghost knife would definitely not give him another chance!
