"It's not for sure, just be careful!" Bai Wen responded and also came to the gate of the research institute.

The ghost acts as a reconnaissance unit, and the door is locked and quickly opened.

There are a total of ten floors above and below the ground, and the upper five floors are office locations, and the real laboratories are underground, but to be on the safe side, they still searched the entire floor to ensure safety.

As soon as they entered the hall, three or four zombies with hideous faces and blood-stained white coats rushed up, Bai Wen didn't dare to let the raiders make a move, and the whole building must not be blown up?

In addition to Bai Wen, the commander, there are also a few young men from Tailong, they have long held back their strength, seeing the three zombies rushing over, they immediately pulled the trigger, and the three zombies were already on the ground with a burst of gunshots, and the three zombies were already on the ground, without moving.

The size of the raiders was too big for the stairs to go up, so Bai Wen asked them to guard the door and be responsible for support.

He led Ghost No. 2 and the four boys to search all five floors upstairs, killing more than a dozen zombies in white coats before coming to the entrance of the basement.

The four boys were a little nervous, and a little excited, just upstairs was an appetizer, the real feast had just begun, this underground was eerie, the sight was not good, and it was a place to study meteorite fragments, God knows what kind of monster would be born?

The metal door slowly opened, and a foul smell wafted out, but fortunately, they were all wearing gas masks, and this was the first thing they could see.

The ghost immediately entered stealth mode, and the whole person disappeared.

To Bai Wen's surprise, for more than two years, there was still electricity here!!

He immediately flipped the switch, and the dimly lit basement lit up, and then they saw a scalp-tingling scene.

The entire basement had now turned into a Shura Hell, with dried blood stains everywhere, and dozens of zombies grinning and screaming terrifyingly!

These zombies are completely different from ordinary zombies, they are blood-colored all over their bodies, as if they have no skin, their blood vessels are protruding, their muscles are bare, and their size is also very huge, and they look like mutants.

When they saw Bai Wen and the others, they suddenly opened their bloody mouths and cracked directly to the back of their heads, revealing a mouth full of fangs and a long tongue full of spikes.

"Ah......" Tai Long was still young after all, and he was so frightened that he screamed, this kind of zombie was the first time they had seen it, how could they not be afraid?!

Bai Wen also had a tingling scalp, but after all, he was a person who had died once, and his mental quality was much better than that of the four boys, so he immediately set up a submachine gun and pulled the trigger to be a shuttle.

The metal nails came out of their disembowels and blew up bloody holes in the zombies, but the zombies didn't seem to be in any serious trouble at all, and they still screamed and pounced.

Bai Wen retreated again and again, and was a little surprised, these zombies are much stronger than those outside, even if the zombies are second-level, although they can't die when the bullet hits the body, they don't recover so quickly, but these are completely different.

Seeing that the zombies pounced again, the four boys also pulled the trigger one after another, and the bullets exploded into bloody holes on the zombies, but they could only slow them down, and they couldn't hurt them at all.

"Hit the head!" Bai Wen took out a pistol and exploded the head of a zombie with one shot, but the zombie without a head was still not dead, and without fangs, they actually opened a big mouth full of fangs in their chests and bit it again.

"! It's a refinement! Bai Wen was furious and immediately shouted at the walkie-talkie: "Come over the evil fire!" Then he led the four boys, and Malier withdrew.

As for the ghost who went in stealth, Bai Wen didn't care, those zombies couldn't see him, he was the safest.

When the two raiders at the door saw this scene, they wanted to make a move, but they were stopped by Bai Wen, their movements were too big, and Bai Wen didn't dare to use them at all.

But it was a very good choice to block the door with them, two tower-like raiders blocking the doorway, leaving the zombies hoarse, leaving only some tooth marks and liquid on their heavy armor.

At this time, the evil fire finally galloped in, and the two raiders immediately gave way to the door, and a tongue of fire erupted directly.

As soon as the tongues of fire up to several thousand degrees swept away, those zombies were ignited one after another, letting out a terrible hiss, and they were quickly burned to the ground.

"Damn, what the hell!" Bai Wen touched the cold sweat on his head and scolded.

"White ...... Big Brother Bai, pick up ...... What do we do next? Li Dan exclaimed with palpitations.

"What else can I do, since I'm here, can I go back empty-handed?" Bai Wen rolled his eyes, plucked up his courage, and strode in again.

Although the four boys were afraid, they couldn't admit it, and they also followed, but this time they were only nervous, and they were no longer excited.

The first floor of the lab has been emptied, followed by the second floor.

The second layer, like the first, also had such zombies, and they were faster, bigger, and more terrifying, so they had to retreat again, lure the zombies up, and let the evil fire burn them fiercely.

In this way, they went down four floors in a row, and when they saw the incomparable zombies, they led them up and handed them over to the evil fire to deal with, which made Bai Wen very angry.

I don't know if there are such terrifying zombies in this fifth layer!!

Carefully pushed open the metal door of the fifth floor of the basement, it was also bloodstained and terrifying, but to Bai Wen's surprise, it was quiet here, there were no zombies, but a ghost appeared beside him, and reported: "The fifth floor has been searched, safe!" ”

Bai Wen couldn't help but roll his eyes, why didn't you report on the four floors just now? They were all scared half to death.

Several people searched in the laboratory and soon found a huge glass container with a meteorite fragment quietly placed inside!

This fragment is much larger than the one obtained in Pi County, the size of a tennis ball, Bai Wen almost drooled, how many crystals can be born from such a large meteorite fragment? !

Just as Bai Wen wanted to take out the crystal, the ghost on the side suddenly shouted: "Commander, be careful!" ”

Then he threw Bai Wen to the ground, but he didn't have time to care about the other four, Li Dan, who had been standing behind Bai Wen, didn't react at all, and a small black shadow directly pounced on his gas mask.

Li Dan only felt a pain in his nose, it should have been bitten by something, he hurriedly slapped the black shadow out and took off the gas mask.

His nose was bleeding and tears were rolling down his eyes.

"What the hell?!" Li Dan shouted, and the thing pounced again, and everyone looked at it, and it turned out to be a blood-red mouse.
