Below the main building, in the open space in the center of the hospital, a three-meter-diameter pit appeared at some point, and a large number of 'rat corpses' crawled out of it.

Dense, as far as Luo Chen could see, the number was estimated to be at least a few hundred, the smallest one was the size of a soil dog, and the big one was the size of a bull.

Those big Luo Chen had never seen them, and the bones on their bodies covered their bodies like armor, and they knew that their defense was not low just from their appearance.

And the worst thing is that those trumpet 'rat corpse brothers' can rely on their sharp claws to scratch through the wall and climb up.

In addition, the large 'Rat Corpse Brothers' rushed directly to the entrance of the stairs with some of the smaller 'Rat Corpse Brothers', as if they wanted to climb up the stairs.

"These things don't have a low IQ!" Professor Mu scolded with an ugly face.

After saying that, he ran out of the room without hesitation.

Luo Chen didn't bother to pay attention to him, because when he looked down, some of the 'Rat Corpse Brothers' had already climbed down the wall to the fifth floor, and then through the window.

Even if the windows are closed, the glass can easily be broken by them. At the very window where he was standing now, three or four 'rat corpse brothers' climbed up.

Luo Chen did not hesitate, grabbed the pistol with both hands and took aim, and pulled the trigger.

Bang bang bang –

Three 'rat corpse brothers' who were close at hand were hit and fell downstairs.

Luo Chen had no intention of staying here, and he quickly exited the room.

When they walked to the corridor, they could see at a glance that the number of 'rat corpse brothers' on the corridor had at least doubled, and Zhao Youyou and Su Shan had no time to aim at all, so they could only set the rifle to fire in bursts and shoot like a submachine gun.

To make matters worse, the 'Rats' who had climbed up the walls outside had emerged from the other rooms and appeared in the hallways, screaming loudly and sharply, rushing towards them, drowning them in a matter of seconds.

At this time, Su Shan shouted: "Luo Chen! The magazine is almost finished! Unstoppable! ”

Luo Chen looked at Zhao Youyou and saw that six or seven magazines had also dropped from her feet. There are actually a lot of magazines of this model that I got from Shi Nan at the beginning, but the average gun is only seven or eight magazines.

At this time, even if there are still bullets left, there is no time to reload the magazine.

If they stay in this position, they don't have any advantage at all.

Luo Chen smashed the pistol without bullets at a 'rat corpse brother', with a backpack behind him and a Mo knife in both hands, and immediately decided: "Go to the rooftop!" ”

Before Luo Chen's words fell, Professor Mu had already rushed to the corridor above.

Seeing this, Na Sushan was not to be left behind, so he actually stopped suppressing the firepower of the 'Rat Corpse Brother', turned around and climbed towards the upper corridor for the second time.

Luo Chen's eyes were cold.

At this time, half of Su Shan's firepower was missing, and Zhao Youyou's gun alone was useless, and the 'Rat Corpse Brother' surged up in the blink of an eye. Not only that, but on both sides of the corridor, a large number of 'Rat Corpse Brothers' figures also rushed towards them.

In three directions, the nearest 'Rat Corpse Brother' was less than two meters away from them, and several 'Rat Corpse Brothers' pounced on them, and the wide open hideous mouthparts made people chill.

The bullets in Zhao Youyou's gun had been shot out, and she still had a magazine, but she was too lazy to change it, so she directly used the rifle as a stick and smashed it out quickly and sharply.

Boom!

A 'rat corpse brother' who pounced in front of her had his entire mouthparts smashed to shreds.

The butt of the rifle is also instantly deformed and distorted under the force.

Luo Chen also raised his foot and kicked away the two 'rat corpse brothers', and the long handle of the Mo knife stabbed one to the side and back, and then shouted at Zhao Youyou: "Don't entangle, go up quickly!" ”

Zhao Youyou didn't say a word, nodded, and his golden pupils were unusually calm.

She didn't pretend to Luo Chen, smashed the useless rifle in her hand at the nearest 'rat corpse brother', and ran towards the stairs above without any delay.

Her movements were very fast, and in two bounces, she crossed Su Shan and Professor Mu, rushed out of the entrance of the building, and reached the roof of the building.

Luo Chen stayed at the end, his speed was not slower than Zhao Youyou, but carrying a two-meter-and-five-long Mo knife, he couldn't be as chic as Zhao Youyou in this narrow corridor.

Therefore, he simply broke off, and went upstairs backwards on one side, holding the Mo knife in both hands, and made a small swing, chopping to death the 'rat corpse brother' who kept trying to pounce on him.

Every time you kill a 'Rat Corpse Brother', an illusory small interface will appear in the corner of your eye, the numbers jump, and a 'Rat Corpse Brother' has an experience point.

After Luo Chen killed more than a dozen 'rat corpse brothers', he finally went up to the rooftop smoothly, and when he rushed out of the exit of the corridor, he saw Zhao Youyou standing aside.

The 'Rat Corpse Brothers' followed, but at the same time as they came out of the rooftop, they were already waiting at the exit Zhao Youyou, each with a machete in each of their small hands.

Two cold rays of light strangled down, and in the piercing scream, blood flowers danced wildly.

Puff puff –

Zhao Youyou's knife method is very direct, without the slightest routine. But the angle of the knife is very precise, the knife speed is fast and fierce, and almost no knife misses.

This girl, who looks petite and weak on the outside, is extremely ferocious at this moment.

This scene fell in Luo Chen's eyes, and he gave her a thumbs up in his heart.

An open, wide, almost obstructive rooftop.

Luo Chen saw Su Shan and Professor Mu running dozens of meters away, the two of them avoided from afar, and they didn't want to help at all.

Su Shan met Luo Chen's gaze and hurriedly explained loudly: "Brother! I'm out of bullets in my gun, and I can't help if I want to! ”

And Professor Mu didn't bother to talk nonsense, just had a gloomy face.

Luo Chen sneered in his heart, and he didn't have time to care about them for the time being, turned around and came to Zhao Youyou's side, and said calmly: "I'll come positively, you make up for the leak!" ”

Seeing this, Zhao Youyou did not hesitate at all and quickly gave up space.

Luo Chenping held the Mo knife, the world seemed to slow down, and the information captured by his eyes was quickly processed by his head, and then his body reacted, and the Mo knife stabbed out.

The two 'rat corpse brothers' the size of domestic dogs pounced fiercely and swiftly at Luo Chen.

Burst!

Double-edged, the sharp, thick blade of the blade easily pierces through their bodies.

"Squeak~squeak~!!" They didn't die immediately, they screamed from their mouthparts, their bodies struggling frantically against their knives, blood splattering.

Luo Chen clenched the long handle, flipped his wrist, turned the blade of the knife, and sharpened it, and the two 'rat corpse brothers' hanging on the knife body immediately split their bodies, and their bodies were separated from the knife body.

The whole process was completed in the blink of an eye.

The exit of the corridor is so big, no matter how small the bodies of the 'Rat Corpse Brothers' are, it is impossible for many to emerge, and Luo Chen and Zhao Youyou alone can seal their way out.

The heavy Mo knife was as light as nothing in Luo Chen's hands, he didn't know how to shoot, but the cold blade was like a poisonous snake's kiss, and every blow could stab one to death.

Zhao Youyou held a handful of chops in each hand and handed it to Luo Chen to deal with, and she relied on her keen insight to solve those things that Luo Chen couldn't take care of.

In less than five minutes, Luo Chen had already earned more than fifty points.

Outside the exit of the corridor, the corpse of the 'Rat Corpse Brother' almost blocked the exit.

However, the situation is not much better because of this.

On the edge of the rooftop, one by one the 'rat corpse brothers' turned up. The corridor was blocked, and this group of 'rat corpse brothers' knew how to be flexible and climbed the wall directly from the outside.

"Help! Save... Help bro!! ”

Su Shan, who was hiding far away just now, asked Luo Chen for help at this time. After those 'rat corpse brothers' climbed onto the rooftop, a considerable number of them stared at Professor Mu and Su Shan. The scarlet eyes glowed with ferocious light, and they frantically rushed towards Professor Mu and Su Shan.

Su Shan and Professor Mu did not hesitate to run back to Luo Chen and them, wanting to rely on Luo Chen's protection, but unfortunately they hid too far just now, a distance of dozens of meters, and without waiting for Luo Chen to save him, the 'Rat Corpse Brothers' had already pounced on them.

Bang bang bang –

The rifle in Su Shan's hand spewed flames and poured bullets.

However, he had just told Luo Chen that his bullets had run out.

"Ahh Save me... Brother ......"

"Fuck off! Low-level garbage! I can't just die!! ”

The ferocious mouthparts tore at the flesh and blood on Su Shan and Professor Mu's bodies, but unfortunately they were just ordinary people, but whenever they were pounced on by the 'Rat Corpse Brother', and their claws pierced into their bodies, no matter how they struggled, they couldn't shake them off.

Professor Mu and Su Shan were quickly overwhelmed by the ferocious 'Rat Corpse Brothers', and the terrible screams continued to come out of them, but it didn't take long for the screams to slowly weaken, and finally only the screams of the 'Rat Corpse Brothers' were left in the carnival.
