"It turns out the door is stuck. No wonder no monster has come for so long. Wait..." Li Zheng was suddenly stunned, "Why did the footsteps come behind us?"
"It's up there!" Xiao Siyuan raised his head and declared mysteriously. A ventilation pipe was erected above the passage. It was shaking due to the chaotic footsteps and seemed to collapse at any time.
Bang!
Just when everyone looked up, a sharp bone spur stuck out of the ventilation pipe, right behind the team.
Fortunately, it was not long enough and did not hit anyone in the team.
Without thinking, Lu Li raised his sniper rifle, pointed it at the bone spur, and fired a bullet.
The slender warhead, as long as an iron drill, penetrated the ventilation duct and accurately penetrated the monster with bone spurs above it. An explosive roar sounded from the ventilation duct.
Zi La La——
There was a harsh scraping sound of metal, and the bone-spur monster survived being shot. It dragged the bone spurs to open the ventilation duct, and dark green sticky liquid flowed down the opened gap.
The members of the team below hid one after another to avoid being contaminated by this mucus, for fear that it might contain biochemical viruses.
"This won't work." Li Zheng judged the situation instantly and said to Xiaoying: "You stay at the door and don't let those monsters rush in. I'll go up!"
"Ouch." Sakura nodded and led Pink Polly to guard the half-open gate.
Fen Poli's pair of iron fists could just pass through the gap in the gate. At this time, he came closer, stretched directly to the opposite side, and started a series of strange punches.
Puff puff puff~
Bang bang bang~
A series of chaotic hitting sounds showed the effect of Pink Poli's attack. A large amount of dark green slime could be seen splashing everywhere from the gap in the gate, and there were constant roars from behind the door.
When Li Zheng saw this, he didn't hesitate. He started the aircraft, rose up from the ground, tore open the ventilation duct with the sharp sword blade, and got in.
He had to prevent the monster in the ventilation duct from going down, otherwise it might cause harm to three less powerful teammates.
Breaking into the ventilation duct, the space here is much wider than expected, and it is even wide enough for two sand trucks to travel side by side.
The height is several kilograms and five meters.
The monster that pierces the ventilation duct with bone spurs looks different from zombies in appearance. The surface of its body is covered with a layer of gray bone armor, and the front end of one arm looks like a mantis, with a long skeletal blade.
There was a terrifying hole in its body, and a large amount of dark green mucus gurgled out of the hole. This was the result of Lu Li's battle.
In addition to this ash-skeletal zombie, there were also a large number of ordinary zombies in the ventilation ducts. As soon as Li Zheng emerged, he was bitten by several zombies.
Fortunately, his reflexes were extremely quick, and with Zhan Zhouzhou's guidance on swordsmanship, he was able to throw out his sheath sword and wipe out all the ordinary zombies around him.
"These zombies are all wearing white coats, are they scientific researchers?" Li Zheng took the opportunity to glance at it. He estimated that these zombies in the ventilation ducts were probably scientific researchers who hid during the outbreak of the biochemical virus. Unfortunately, they eventually died.
There is no way to escape the virus infection.
"Kill that big monster first, before it jumps!"
Shaking off the slime on the sword, Li Zheng activated the characteristics of the Beholder Boots and instantly appeared three meters away, just in front of the gray-bone zombie.
The long sword advanced, and Li Zheng wanted to take advantage of the opponent's bone blade stuck in the pipe to capture it in one fell swoop.
"Roar~!" The gray-bone zombie roared loudly, pulled out the bone blade with a clang, and slashed Li Zheng horizontally.
These monsters are not afraid of death and have no thinking ability, only instinct.
If Li Zheng did not retreat, he would probably be cut in half by the gray-bone zombie at the moment he killed it.
"Power Demon·Crazy Transformation!"
The incarnation of the furious force demon appeared. Li Zheng resisted the attack and successfully penetrated the brain of the gray-bone zombie with one sword.
Feeling pain in his waist, Li Zheng was pushed back two steps by the gray-bone zombies. He swung his sword horizontally and cut off several ordinary zombies that were surrounding him.
Li Zheng reached out and wiped it on his waist. There was no blood or even scratches on his skin. Li Zheng felt relieved immediately.
He was afraid that he would be infected by the virus even if he had a slight skin injury. Fortunately, the defense of the incarnation of Li Mo was still very strong and it was not penetrated.
欻欻!
Li Zheng was weaving back and forth in the ventilation ducts, using Zhan's sword moves repeatedly, plowing through all the zombies.
After making sure that there were no survivors, Li Zhengcai returned the same way and fell below.
Puff puff puff~
Bang bang bang!
Fen Poli was still unleashing a series of strange punches, and the sound of blows on the other side of the gate basically never stopped.
Xiao Siyuan and other long-range attackers were not idle, taking the opportunity to shoot out from the gap in the gate, but they could not guarantee the effect.
"Sakura, you two get out of the way!" Li Zheng gave the order, raised his sword and rushed to the gate, slashing it open twice.
The incarnation of a violent and violent demon holds a diamond-grade sheath sword, and cutting the metal gate is no different from cutting tofu, very easy.
Li Zheng raised his foot and kicked open the fragments of the gate. After rushing over, he found that the environment here had changed. There were many small rooms on both sides of the passage.
A large number of zombies were locked inside. There were transparent glass-like materials on the door and walls of the small room. It seemed very fragile, but it could prevent even those zombies from being hit.
"Experimental object observation room?" Li Zheng recognized this kind of house that often appeared in Hollywood science fiction movies at a glance, and he felt awe-struck in his heart.
Those frogmen in white coats are actively creating zombies and imprisoning them for research!
It's just that for some unknown reason, the virus spread in areas where it shouldn't be present, causing the researchers in the entire biochemical laboratory to die suddenly and become one of the people under observation.
In the passage, or corridor, the zombies here have been beaten to a pulp by Pink Polly. They are sticky and wet when stepped on, and it feels extremely disgusting to the touch.
"The difficulty of this second-level dungeon doesn't seem to have improved much?" Li Zheng quickly checked in the corridor and found a few lone zombies, with a sword on their heads.
Soon, only the experimental subjects in the observation room were still active in this area. They roared hoarsely when they saw living creatures, clinging to the transparent material, staring at Li Zheng, with a look of extreme longing in their turbid eyes.
.
"This scene reminds me of the slave era mentioned in textbooks. The imprisoned slaves probably behaved like this when they saw the heroes who rescued them." Xiao Siyuan crossed the gate and looked at the observation rooms, sighing.
"That's much worse." Lu Li walked 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 waited for them all to come over before entering with a complicated expression.
Originally, she was supposed to be doing Li Zheng's work, but now she was left behind to protect her, which was hard for her to accept.
"The exploration level is only 10%, which means we haven't encountered a formal attack so far. Maybe the zombies in these rooms are also the targets of our cleanup." Zhan Zhouzhou pointed at a room with his sword and said, "They are all ordinary ones.
Zombies, let’s spread out and clean up this place to save time.”
