Inside the demon cave, there is flesh and blood all over, also known as flesh and earth.

Meat soil is multiplying and spreading every day.

Constant upward encroachment.

The Legion's greatest role is not only to defend against the invasion of demonic creatures, but also to regularly invigorate the flesh and soil.

When the flesh and soil should be inactivated, you can easily know by looking at the color.

At normal times, the color of the meat soil is sallow, like air-dried bacon, with a faint fishy smell.

In the fleshy area near Cadilla City, most of them are this lifeless color.

However, if you go deeper into the demon cave, the color of the flesh and soil will gradually turn red.

After crossing the safety line and entering the bone layer of the demon cave, the color of the flesh and soil gradually turned dark red.

This dark red flesh soil is like rotten stinky meat, which not only exudes a disgusting stench, but is also full of various parasites.

The rotten meat soil, even more like a broth swamp, not only stinks, but also bubbles up from time to time, spraying rotten meat crumbs outward.

If you want to walk in such a harsh place, ordinary people can only wear thick protective clothing.

Every time you go out, you have to check it carefully, because if you make a mistake, the parasite eggs in those rotten meat crumbs will be activated in an instant, and they will be extremely ferocious and rush into the inside of the protective suit.

In the words of those researchers, the waxy flesh soil activity is almost gone, and no demon cave creatures can be born.

The dark red flesh soil is slightly active, and various small demon cave creatures will be born in it.

Most of these creatures are mainly insects.

Very few will spawn flesh plants, or large flesh creatures.

In addition to the somewhat disgusting appearance, whether it is a plant, a creature, or a bug, you can find a prototype in the watch world.

However, if you dissect these creatures and plants in depth, you will find that they just look alike.

It's a bit like going public in the backdoor, or applying similar things to paralyze your opponent and then devour it.

Of course, these monsters aren't just for outsiders who have broken into the caves.

They also fight, fight, and devour each other.

It looks a bit like an ecosphere, but it's not.

The ecosystem is balanced, and the Devil's Cave never talks about balance.

After a large number of monsters fight each other and devour each other, the strongest one will eventually be born.

This kind of monster that grows up without knowing how many of its kind have devoured is also known as a derivative demon cave creature.

In fact, the original intention of the official to do this kind of research was to make an intuitive ranking of the strength and weakness of the creatures in the demon cave.

It's a pity that the study failed.

Because they found that the so-called derivative is more like an entry ticket.

The weak one can't beat a dog, and the strong one has a domain force field, which is basically the same as the lord creature class.

Even a slap in the face can destroy the Enlightenment Academy.

If it weren't for the annihilation bomb in the hands of humans, the high-level demon cave creatures with a high IQ would have thrown a rat trap on this.

Maybe this battle between humans and the demon cave will end early.

-------------------------------------

At this moment.

Shermir stared out the window at the huge skeleton that looked like a demon god.

His eyes were full of disbelief.

"How is this possible? How can strong derivatives appear on the periphery of the bone layer? ”

Strong derivatives?!

Romy's face turned pale in an instant.

Kaisheng suddenly stood up from his seat.

Even Li Boyang couldn't help but look out the window.

They have studied for so long, not to mention proficient in "Demon Cave Biology", at least they have all read it.

Of course, it is very clear what exactly the so-called derivatives mean.

There are only three tiers of tokens in total.

One primordial creature, two weak creatures, and three strong creatures.

The primary tokens, the weak ones are basically the same as cats and dogs, and the strong ones are almost equivalent to the lion and tiger, barely advanced.

Intelligence is also similar to that of cats and dogs, and basically relies on instinct to act.

Weak derivatives are said to be weak, but they are not weak at all.

Because the derivatives of this stage have begun to gradually have extraordinary properties.

Or super recovery ability, or acid spray, or simply liquefied body, and all kinds of strange abilities.

The IQ is like that of a seven or eight-year-old child, and he is not very smart.

And the upper limit of weak derivatives is very high, the weakest also has a second-order lower rank, and the strongest can almost reach the peak of the fourth order.

Romi's eyes darkened, and his heart was full of thoughts.

The details of the three major systems flashed through his mind-

Alienation system: first-order martial arts base→ second-order parasitic ecology→ third-order co-ecology→ fourth-order manipulation state→ fifth-order semi-colonization state→ sixth-order full-colonization suit→ seventh-order giant colonization suit→ eighth-order ???

Burning Blood System: First-Order Martial Dao Body→ Second-Order Innate Body→ Third-Order Blood Exchange Body→ Fourth-Order Burning Blood Body→ Fifth-Order Flame Blood Body→ Sixth-Order Red Flame Body→ Seventh-Order Red Yang Body→ Eighth Order???

Mindfulness system: first-order strong gods→ second-order kinetic thoughts→ third-order subtleties→ fourth-order perception→ fifth-order floating → sixth-order flying heaven→ seventh-order Sumeru→ eighth-order ???

The third order doesn't seem to be very high.

But compared to the steam armor on the side of the Ministry of Science and Technology, its strongest combat power is only second-order.

The current strongest human race is only of the seventh order.

And that's just weak derivatives.

And now the giant skeleton outside is a strong derivative!

The weakest is also against the fifth-order lower position!

What is the equivalent of the fifth order? It is equivalent to the semi-colonization state of the alienation system, equivalent to the flame blood body of the burning blood system, and also equivalent to the floating air of the mind system!

What makes Romi a little tired is that this is only the weakest strong token!

If this is a little stronger, strong enough to be able to compete with the sixth order of the lord level, it is obviously not surprising.

What's worse is that strong tokens have a high level of intelligence!

Not only strong, but also brainy!

Just by going through this information in his mind, Romi felt a wave of powerlessness and despair.

The Shemir mentors who escorted them were at most at the bottom of the fifth order, and they would naturally be a head weaker against strong derivatives of the same rank.

It's not that the academy doesn't pay attention to them, but no one would have imagined that a strong derivative would emerge on the periphery of the bone layer.

It's completely impossible to happen.

Ridiculous.

"Romy! Perk up the dots. ”

"Think of your father."

"Your negativity will draw that strong token to you."

Li Boyang said, reaching out and patting Romy's head.

Romi shuddered and pulled away from his inexplicably low emotions.

"Good...... What a terrible polluting force. ”

"Just a few glances can make such a big difference to me."

"Silent ...... It's horrible. ”

"Your mental power is a little weak, so it's susceptible."

"Fortunately, your will is clear, so you can wake up instantly when you are reminded of it."

Teacher Shemir explained, but his face was not good-looking when he spoke.

Li Boyang walked to the narrow window, looked out, and suddenly said, "The hovercraft we are sitting on is confirmed to be driving?" ”

"The hovercraft is always moving, we can all feel it, you certainly don't say this for no reason, what did you find?" Kaisheng vaguely felt that something was wrong, but what it was, he couldn't say it when the words came to his mouth.

"It's the location."

Li Boyang sighed, "That huge skeleton, the location of our hovercraft...... Little has changed. ”

"If the hovercraft is moving forward, then the huge skeleton is standing still, and it should be moving away, right? But why is it so far away from us? ”

"There are only two possibilities that can cause this special situation."

"Either this strong token has a powerful hallucination ability."

"We've actually been stuck where we are, we just don't know yet."

"Either the strong token has the spatial ability to lock onto our hovercraft and target us in a way that is almost constant."

"No matter which one is before or after, it's extremely troublesome."

"I'd rather be an illusion than a space." Kaisheng muttered.

Li Boyang nodded, "I think the same way." ”

"The hallucinations seem unsolvable, but there's still a chance."

"Space...... I think we'd better wash and sleep and die a decent death. ”

"Don't laugh, since you say so, there must be some guesses, so let's just say it." 、

Kaisheng was speechless, when was this time, and joking.

Teacher Xie Mier on the side, looking at Li Boyang's eyes was also extremely complicated.

Obviously, after listening to Li Boyang's words, the strongest teacher discovered all kinds of clues and recognized the truth of the facts.

As a teacher, you also need to be reminded by students before you know what the truth looks like, which is really embarrassing.

"It's very simple, if you look at the scenery outside, you will naturally know what's going on after a long time."

Li Boyang pointed to his brain, "That monster, if it is an illusion, then the illusion must be based on our cognition, and then unfold." ”

"In other words, in our cognition, what the fleshy desert outside looks like, then what the scenery outside the window ultimately presents to us is what it looks like."

"So you just have to look out for a little while and you'll see a lot of ...... It's like I've seen something somewhere, but it doesn't seem to be the same. ”

"It's probably some kind of change to avoid the illusion being seen through quickly."

"Figuratively, it's like inserting a random variable value."

"Make the scene in front of you plausible, and it won't be so easy to see through."

Is that so?

Romi scratched his head, feeling as if he understood, but not completely.

He looked out the window, not daring to look at the huge skeleton of the demon god, but instead focused on the scenery around him.

Sure enough, after a while, he had a strange sense of familiarity with the scenery outside the window.

Romy was stunned for a moment, is it so easy to see through?

But looking back, I think about it.

If the senior brother didn't say it, would he be able to notice this insignificant detail?

Definitely won't notice.

I'm scared enough, how can I notice this.

Kaisheng was not surprised by this, and in his opinion, there was nothing surprising that the monster would do anything.

Instead, he asked, "Now we can be sure that we've fallen into the illusion of a powerful token. ”

"So how do you break the game? How can we get out of the illusion? ”

"What's more, the driver also has to get out of the way, after all, I can't drive a hovercraft."

Li Boyang smiled lightly, "No, it's not over yet." ”

"Since it's an illusion, how can you be sure that the strong token is real?"
