Shen Chen, who saw the prompt, still frantically pressed the elevator button, but it was all in vain.

"Reload!"

Li Bing's magazine was empty again, pressed the debounce button, loaded a new magazine, pulled the trigger and fired, and the action was completed in one go.

And in the interval between his reloading magazines, Xue Yang's shooting rhythm became significantly faster to fill the firepower gap formed by Li Bing's reloading.

When Xue Yang changed the ammunition, Li Bing would speed up the pace of shooting, and the two cooperated very tacitly.

"Aren't you alright?" Xue Yang took the time to shout.

At this time, the number of zombies rushing in at the door was increasing, and the two had to pull back while firing to clear the shooting range.

"No! The door is locked! Shen Chen turned around and shouted loudly.

"Then leave it alone, let's clean up the zombies first."

Hearing Xue Yang's slightly anxious shout, Shen Chen knew that their current situation was not optimistic.

Gritting his teeth, he pulled out the ring and put it in his arms, turned around and ran towards the two of them with his rifle in his hand.

"Chirp! Chirp tweet! ”

Pulling the trigger is a series of bursts.

Xue Yang was taken aback by Shen Chen's actions, and hurriedly shouted, "Damn!" Don't use a rifle, change a pistol. ”

"Why?"

Shen Chen was a little puzzled and continued to shoot.

"Rifle bullets are prone to ricocheting in tight spaces."

As soon as he finished speaking, a bullet that passed through the zombie's head and hit the blast door bounced back, hitting Shen Chen's helmet right on.

Shen Chen only felt as if his head had been smashed with a brick, and his body was taken a few steps back with the force of the impact.

Looking at his situation, Xue Yang knew that he had been tricked, "How is it okay?" ”

"It's fine!" Shen Chen shook his head and replied.

Although he said that it was okay, he was afraid for a while, if it weren't for the safety of several people who came in with full arms, it was estimated that he would have to take his life.

Flick your rifle back and use your pistol to continue shooting zombies.

Although the firepower of a pistol is not as good as that of a rifle, it is still possible for three people to hold a door.

At this time, there were no more than a dozen zombie corpses lying on the ground, but there were still zombies pouring in behind the small door.

Just when the pistol bullets of several people were about to run out, no zombies rushed in behind the door.

"Whew!" Shen Chen breathed a sigh of relief.

At this time, this small disinfection room was filled with all kinds of strange smells, including the smell of disinfectant water, the smell of gunpowder, and more of the rancid smell emitted by zombies.

Several flavors were mixed together, choking several people with a straight cough.

"Ahem! It's really good on this taste. Hurry up and get out. Xue Yang said with a frown.

"Looks like we can't get out for the time being." Li Bing said.

"Why?"

"The elevator is locked, didn't I just say that?" Shen Chen's interface said,

"Damn! I'll check it out! ”

After speaking, he turned around and walked behind him, and tinkered with the elevator door for a long time.

Xue Yang walked back with a dejected expression.

"That's right, the elevator door can't be opened anymore, what should I do now?"

"Actually, when we came in before, I was curious about why there was a reminder that the lockdown was lifted, thinking that it should be that the institute didn't know what was going on, which caused the people inside to be infected with the zombie virus.

In order to prevent the spread of the virus, the lockdown mechanism was activated, and after we lifted the lockdown outside, we encountered another zombie attack, which caused the institute to be locked down again. ”

Shen Chen said with his hand against his chin.

"What did you say about the Resident Evil movie, what kind of bird's nest or something..."Xue Yang's computer head tried to recall.

"The Hive Virus Lab under the Raccoon City Umbrella Company." Li Bing said.

"That's right, do you think this is also a virus lab, and the TX virus on it also leaked out from here." Xue Yang's face became solemn.

Shen Chen said thoughtfully: "It's not impossible, but it's too early to draw conclusions, anyway, I can't go up now, so let's just look for and see if there are any survivors here!" ”

Xue Yang and Li Bing agreed, now that they were trapped below, if they could find the staff in the research institute, maybe they would be able to find a way to get out.

....

"Safety!"

Xue Yang was the first to walk out of the disinfection room, checked the situation around, and made a safe gesture to the two behind him.

The trio walked out of the disinfection room and came to a place similar to a waiting area.

This is supposed to be the place where the research institute is waiting to be disinfected, which explains why dozens of zombies stormed the disinfection room.

Looking at the situation at the scene, those people inside should have been sealed in the waiting area and attacked by zombies in order to escape from the research institute.

This can be seen from the human bones scattered on the ground and the corpses of a few zombies on the ground.

Li Bing, who was squatting on the ground to check the corpses of zombies, stood up and said to the two: "Gunshot wound, it seems that there are also security personnel in this research institute." In this way, it seems that the probability of finding a survivor is much greater. ”

"It had better be! Look for an internal map of the institute to see if there is any. Shen Chen said.

"Good!"

Several people began to rummage through the waiting area, and Shen Chen found a floor plan of the institute in a table similar to a personnel registration office.

"Found it!"

He held up the map and gestured to the other two.

The three of them gathered around and studied the map.

"This is where we stay, and the area of this institute is not small according to this ratio!" Xue Yang nodded and said.

"Well, and this institute is a hundred meters underneath, and I don't know how they built it." Shen Chen looked at a sign on the map marked with the distance from the ground, and couldn't help but feel a little emotional.

"This must have been converted from a cave underneath!" Li Bing analyzed.

Shen Chen nodded, looked at the several areas that were divided into several areas on the map, and asked, "Let's talk about where to go first!" ”

Li Bing pointed to an area marked as a high-risk experimental area, "Generally speaking, the protection of this kind of high-risk experiment will be very strict, that is to say, the protection level will be very high, if I am a person here, and then learn that the research institute is blocked and cannot get out, I will definitely choose this place to wait for help." ”

Looking at the high-risk experimental area that was only three or four areas away from him and the others, Shen Chen hesitated.

"Looking at the ruler on the map, there is at least a distance of two kilometers from us to there, and we don't know how many people in this laboratory have turned into zombies. Will it be dangerous to rush forward, if we encounter a few mutant zombies, the three of us may not be able to deal with it. ”

Hearing this, Li Bing frowned, he knew that Shen Chen was also right.

Now they don't know the specific situation outside, and the ammunition on the few people is not very much, if they encounter too many zombies at one time, there will definitely be no bones left to be gnawed by zombies if the terrain is not as favorable as before.
