"It turns out that the door was stuck. No wonder no monsters have come here for so long. Wait..." Li Zheng was stunned suddenly, "Why did the footsteps go behind us?"

"On it!" Xiao Siyuan raised his mysterious declaration, and a ventilation duct was built above the passage. At this time, it was trembling due to the messy steps, as if it would collapse at any time.

Bang!

Just as everyone was looking up, a sharp bone spur pierced from the ventilation duct, right behind the team.

Fortunately, the length was not enough, so there was no one in the team.

Without thinking, Lu Li raised his sniper rifle and shot a bullet above the bone spur.

The slender bullet like an iron rod penetrated the ventilation duct and accurately penetrated the monster with bone spurs above. A roar sounded inside the ventilation duct.

Hilara-

The harsh metal scratch sounded, and the bone spur monster was shot and was not dead. He dragged the bone spur to open the ventilation duct, and the dark green sticky liquid flowed down the cut gap.

The team members below avoided the mucus to prevent it from being contaminated with, for fear that it contained biochemical viruses.

"This won't work." Li Zheng instantly judged the form and said to Sakura: "You guard the door, don't be rushed in by those monsters, I'll go up!"

"Aowu." Sakura nodded and guarded the half-open gate with Fan Poly.

Fan Poli's pair of iron fists just happened to pass through the gap in the gate. At this time, he approached and directly reached to the opposite side, opening the strange fist to hit him.

Puff puff puff ~

Smack sex~

A series of chaotic hits showed the effect of Fan Poly's attack. From the gaps in the gate, you can see a large amount of dark green mucus splashing everywhere, and roars behind the door continued.

Seeing this, Li Zheng did not delay, and started the aircraft, rose from the ground, and the sharp blade tore open the ventilation duct, and he got in.

He wants to stop the monsters in the ventilation duct from going down, otherwise it may cause damage to three teammates with slightly lower strength.

After entering the ventilation duct, the space here is much spacious than expected, and the width is even enough for two mud and sand trucks to run in parallel.

The height is even a few kilograms and five meters.

The monster that pierces the ventilation duct with bone spurs looks different from the zombies from the outside. The surface of the body is covered with a layer of gray bone armor, and the front end of one arm is like a mantis, with long bone blades.

There was a terrifying hole on its body, and a large amount of dark green mucus gushed out of the hole, which was Lu Li's victory.

In addition to this ashes bone zombie, there are also a large number of ordinary zombies in the ventilation duct. As soon as Li Zheng emerged, he was scratched and bitten by several zombies.

Fortunately, his reaction ability was extremely fast, and after Zhan Zhouzhou's swordsmanship guidance, the scabbard sword repeatedly threw out the sword light and cleaned up the ordinary zombies around him.

"These zombies are all wearing white coats. Are they scientific researchers?" Li Zheng took the opportunity to glance. He estimated that these zombies existing in the ventilation ducts were probably scientific researchers who hid in when the biochemical virus broke out. Unfortunately, they were unable to escape the virus infection in the end.

"Kill that big monster first so that it won't jump down!"

After swaying off the mucus on the sword, Li Zheng activated the characteristics of the Eye Demon Battle Boots and instantly appeared three meters away, just in front of the Ashes Bone Zombie.

The long sword advanced, and Li Zheng wanted to take advantage of the opportunity when the opponent's bone blade was pierced in the pipeline and take it down in one fell swoop.

"Roar~!" The ashes zombie roared, pulled out the bone blade and slashed Li Zheng horizontally.

These monsters are not afraid of death, have no thinking ability, and only have instinct.

If Li Zheng did not retreat, he would probably be cut into two pieces by him in the middle of the moment he killed the Ashes.

"The Demon of Power·Crazy!"

The incarnation of the power demon, representing the emergence of the rage, Li Zheng resisted the attack and stabbed into the brain of the gray bone zombie with one sword.

After a pain in his waist, Li Zheng was beaten back by the gray bone zombie, and he swung his sword horizontally, cutting off the several ordinary zombies surrounding him.

Li Zheng immediately felt relieved when he reached out to touch his waist, without any blood and even his skin was not scratched.

He was afraid that he would be infected by the virus if he was slightly injured by a point of skin. Fortunately, the defensive power of the incarnation of the Li Demon is still very strong and has not been penetrated.

Shrink!

Li Zheng was interspersing back and forth in the ventilation duct, and Zhan used his sword moves one after another, plowing all the zombies.

To ensure there is no living, Li Zhengcai returned the same way and landed below.

Puff puff puff ~

Slap sex!

Fan Boli was still using strange fists to hit him, and the sound of blows on the other side of the gate basically did not stop.

Xiao Siyuan and other far-distance attackers were not idle either. They took the opportunity to shoot out of the gap in the gate, but they could not guarantee the effect.

"Sakura, you two get out of here!" Li Zheng gave the order, raised his sword and rushed to the gate, and split it a few times.

The violent demon is transformed into a hand-held diamond-level scabbard. Cutting a metal gate is no different from cutting tofu, and it is very easy.

Li Zheng raised his feet and kicked open the fragments of the floodgate. After rushing over, he found that the environment here had changed, and there were many small rooms on both sides of the passage.

A large number of zombies were locked inside, and there were transparent materials similar to glass at the door and on the walls of the small room. They seemed very fragile, but they could even defend against those zombies when they hit.

"Experimental Observation Room?" Li Zheng recognized this kind of house that often appeared in Hollywood science fiction films at a glance, and his heart was suddenly filled with awe.

Those frogmen in white coats were actually actively creating zombies and being detained for research!

But for some reason, the virus spread in areas that should not have appeared, causing researchers in the entire biochemical laboratory to die collectively and become one of the observers.

In the passage or corridor, the zombies here have been beaten into a ground meat sauce by Fonopoli. They are sticky and soft when they step on them, and they feel extremely disgusting.

"The difficulty of this second-level dungeon does not seem to be much higher?" Li Zheng quickly checked in the corridor, found several lonely zombies, and beheaded with a sword.

Soon, only the experimental subjects in the observation room were left in this area to move. When they saw living creatures roaring hoarsely, they clinged to the transparent material, staring at Li Zheng tightly, and looked extremely eager in their turbid eyes.

"This scene reminds me of the textbook mentioning the slave era. It is probably the same when the detained slaves saw the heroes who rescued them." Xiao Siyuan crossed the floodgates and looked at the observation rooms, sighing.

"That's much worse." Lu Li came over with a sniper rifle. "What the slaves want is freedom, and what they want is to tear us into pieces or become one of them."

Zhan Zhouzhou came to the scene before he entered here with a complicated expression.

Originally, she should have done Li Zheng’s job, but now she is left to protect by everyone, which makes it difficult for her to accept.

"The exploration is only 10%, which means that we have not encountered a formal attack yet. Perhaps the zombies in these rooms are also our target of cleaning up." Zhan Zhouzhou pointed at a room with his sword and said, "It's all ordinary zombies. Let's scatter the place and clean it up to save time."

As she said that, she wanted to go and open the room.

"Wait!" Li Zheng called her.
Chapter completed!
