"Devil's laboratory? Is it a demon of the demon?" Celia said just now. The depth of this space is exactly the area where the underground demon tribe built, so it is not an exaggeration to think about Li Ang in such an association.

However, before the little fox could answer, the scabbard girl denied his speculation: "This is not the territory of the demons, and this can be judged from the temperature. The demons that coexist with the fire element live in high-temperature areas. Although the temperature here is very suitable for humans, it is too cold for the demons."

Too cold? Hearing this statement, Li Ang suddenly recalled some knowledge from the Earth era: "Every time they go deeper into the ground, the temperature around them will rise by three degrees." Judging from the area where they are now deep into the ground, this room temperature is indeed a bit lower than the area where they are located.

Where did the excess temperature go? What keeps this space low? What is providing light to this wonderful underground world? After the scabbard girl said "It's too cold", Li Ang took into account the possible answers to these questions in an instant.

"It's too cold for the demons...that means that the temperature here is artificially controlled, right? Simply put, this is an artificial underground world that uses geothermal heat to provide energy?" Since you can dig a library underground, it is not impossible to dig a small world deeper and deeper underground. Moreover, there is a nearly omnipotent technology like magic in this world, so Li Ang made a bold inference.

The scabbard girl nodded and said, "'It's not bad!' Lord Celia praised her like this, and your inference was completely correct."

"So who is the one who created this world? It shouldn't be Engel?" After his guess was confirmed, Li Ang raised a new question. The scabbard girl also immediately replied: "'You guess.' Lord Celia did not want to answer this question, although according to the data analysis, here 89 is the alchemy world created by Mendel."

"Mendel... the so-called demon refers to Mendel, right?" This time Li Ang asked the little fox.

But she continued to squat on the ground and hugged her head in fear: "I don't know...I don't know anything!"

"Calm down" Li Ang squatted down and held her trembling body with his hands, then comforted: "It looks safe here, doesn't it? What exactly makes you so scared?"

The tails that were shaking into sieve tightened together, and they shook their heads desperately. "I don't know... I really don't know... I should be afraid of nothing even if I have my elder brother around me, but my body is so scared!"

Although I don’t know what I’m afraid of, my body is so scared. What’s going on? Li Ang doesn’t understand very well, because the little fox is not the kind of girl who says she doesn’t want it but has a very honest body.

Feeling Li Ang’s doubts, the scabbard girl next to her explained:

"This is a fear engraved into instinct, just as most beasts are born to fear fire."

Is the instinct engraved into the body? As Li Ang was puzzled, the little fox shook even more violently.

"They...they... are here!" The little fox in horror shouted inexplicably, then the unidentified blue sky was suddenly torn apart, and then countless "people" fell down like dumplings.

As those people fell, the unique rotten aura of undead creatures instantly spread to Li Ang.

"It seems that my intuition is right. There are indeed many undead creatures here!" After the undead fell from the sky, Li Ang was not as worried as before, so he was much more confident when speaking. Seeing the little fox being scared like that, he thought something amazing would appear. After discovering that it was the undead creature he was good at dealing with, he felt much more relieved.

And his scabbard was still as cautious as ever: "Please be careful, these undead creatures are not as simple as imagined - if this is really Mendel's laboratory."

Shortly after the scabbard girl finished speaking, a dozen zombies rushed towards the place where Li Ang was - yes, they "rushed" over and used a running posture to sprint towards the target.

As Li Ang said before, the offensive and defensive abilities of zombies are amazingly strong, and the only weakness is that they are insufficient mobility. Even the second form of "Zombie King Ske" can only move in a step manner, and ordinary zombies are even less mobility. Therefore, the usual tactic of fighting zombies is to fly kites: know the enemy's shortcomings and attack the enemy's shortcomings.

Now that these zombies have suddenly switched to running, Li Ang lost most of his advantage in an instant.

"Damn it, don't you play like this? Is there a 'safe door' nearby?" When it comes to zombies running, there are similar works on the Earth plane. When I think of that work's best way to deal with zombies is to hide in the "safe door", Li Ang blurted out this keyword.

But there was not even a decent building nearby, let alone a "safety gate", so in the second time, Li Ang pulled out the magic sword from the scabbard girl's chest, and then took the sword blade and took a fight.

"Since Lord Celia is still hosting the live broadcast, the magic sword now only has magic bonus and will not guide you with sword skills. So please be more careful when fighting." After being pulled out of the core from his body, the girl squatted on the ground with her broken bra and leaned against the trembling little fox, which seemed like a pair of sisters were unable to resist after being beaten.

Although Li Ang really wants to complain: You guys do this, it seems like I am "ruthless in pulling out the ruthless in my mouth". But considering that I really pulled something out of her body ruthlessly, Li Ang could only control his mouth.

Not long after holding the magic sword, the fastest-running zombie had already arrived near Li Ang. Although there was no guidance from Celia's swordsmanship, Li Ang today was not an ordinary boy in the Undead Mountains, so no surprise, Li Ang easily cut off the fastest-running zombie.

Seeing that the zombies behind were still a little distance away, Li Ang drew a circle on the ground with his sword and circled the two girls who had lost their combat power. Then he held the sword horizontally, then made a high-end and atmospheric move and made a bold statement:

"No one can cross my sword!"

But as soon as he finished speaking, the crack in the sky suddenly spread. Before he could understand what the situation was, various corpses fell down. A world full of vitality instantly turned into a purgatory on earth. What's more troublesome than the mountains of the Dead is that no one knows when this zombie rain will stop. (To be continued.
