The orcs weren't sure at this time, but at the moment there was no other way but to take a risk.

Although he had only read some information about Demon Mica from books, he believed that only Demon Mica could save them at such a moment.

Although the orc said on the surface that it didn't matter if he died or not, he still had some hope of wanting to live.

The half-orcs grabbed Cao Rui and began to jump between the empty islands, the way the half-orcs drove in the air seemed to be a bit special, it simply looked like a fart, but it was actually spraying some gas from their feet, it seemed that they had already done a good job of transforming their bodies.

In this way, the two of them returned to the central Sky Island, at this moment, quite a few buildings on the Big Sky Island looked crumbling under the storm, but in fact, the core building body was still not destroyed, as if there was some unknown force protecting it.

Cao Rui was extremely cautious at this time, because of the existence of armor before, he could cover his whereabouts, so he was able to see some scenes through the wall, but now the situation is different, after all, those two insects are too mysterious to determine what kind of origin they are.

But the orcs were behaving differently, or rather unexpectedly, at the moment.

"What are you afraid of? At this time, caution is useless, you have demon mica, in this place, maybe you can crush those two insects, in short, it is a matter of time before we are discovered, since this is the case, don't hide it, just go forward and see what the situation is.

For other empty islands, this is the only place where there may be some mysteries. If there is a way to get out of this place, it is only behind this stone wall in front of you."

The orc seemed to be fearless, what he said was indeed true, Cao Rui slowly stood up after thinking for a while. He flicked his left hand and began to walk straight towards the front of the stone wall.

His gaze first did not look at some of the inside of the stone wall, as it seemed as if there was a lot of space inside, and it was deep.

Cao Rui's first glance was the big pattern on the ground in front of him, which looked quite infiltrating.

The pattern seems to be composed of two parts, one in front and one behind, impregnated with the blood of centaurs and tigers, and of course other orc members.

At this moment, the flesh on the ground had disappeared, leaving only blood-colored grooves. Except for the faint glow of the pattern in the center, the others have dimmed.

In the central building, the number of bats is already very small, and their carcasses are piled up next to them, as if they have been deliberately cleaned.

"Anyway, these bats are just killed by you when you come in."

The orcs shook their heads: "We were already like this when we first came, although it looks like these things have just died, in fact they have been dead for a long time, just because this place is an ancient relic of the underworld, and there is a special soul power that imprisons these bats, so this makes their bodies look like they have died freshly, but in fact this is just a factor of the environment.

By the way, have you ever noticed the glow on this building? I remember it used to be brighter, but why is it so much darker now?"

Cao Rui only found out at this time that the luminous objects on the top of these buildings were really much dimmer, but he couldn't explain what the reason was for this, so he simply looked at it.

"Let's go, let's take a look first."

It may be that the words of the half-orc before made Cao Rui full of confidence, and he walked into the stone wall, which was a passage that looked quite long, although it was full of danger, but he never encountered substantial danger.

The half-orc stood next to Cao Rui, and his heart was also pounding. At this time, he was also prepared for some battle, his hands turned into huge spikes, and he made a defensive stance. Keep your eyes on the surroundings to see if anything is unusual.

But after walking a long distance, nothing happened, and according to the distance, this length has exceeded the distance of the entire Sky Island, and it is clear that there is another space behind the stone wall.

Eventually, at the end of the passage a bronze door appeared, with a pattern similar to that of Tai Chi on it, with two grooves above it, and two dried and dead bugs curled up in the grooves.

Cao Rui didn't know why, at this moment he seemed very calm, as if he knew that he had infinite resurrection, so he was more bold in doing anything, he stepped forward to touch the metal, and carefully observed the two insects in the grooves of the two Tai Chi patterns.

"It's supposed to be these two bugs, their big horns that have been broken......

Naturally, the orc didn't know these two insects, but he also stepped forward to observe carefully, first touching the bronze door, and then observing the Tai Chi pattern.

"No, it stands to reason that behind the stone wall there should be something we might need, but why is it this bronze door in front of us, except for a long passageway.

Based on what we've learned, it stands to reason that this can't happen. This is seriously different from our expectations.

Then I think it proves that our operation is not what it seems, and what we want may be completely different from the real goal of this operation.

Centaur and Centaur dared to do this, I don't think they had been instructed in some way, because we created it together, and I don't know him very well, and since this bug crawled out of them, I think it should be controlled.

If everything is certain, what is the purpose of these two bugs? Is it just to sacrifice yourself and set it on this bronze door?"

Cao Rui made a new discovery at this time, although the bronze door was intact on the surface, but there was a gap at the bottom, and this gap seemed to be not quite a fit. It appeared so suddenly.

Cao Rui then lay down and looked inside through the gap under the door.

"I've just tried the bronze door, it shouldn't be possible to open it with brute force, there is indeed something inside, I'll try it with my left hand, it's an underworld thing after all."

Then the orc took two steps back, and Cao Rui raised his left hand and began to prepare to exert force, but with a slight push, the bronze door was directly opened. This surprised Cao Rui a little.

The moment it was opened, the storm erupted from the outside again, and this time the storm was even stronger.

This kind of storm of strength can't be resisted by half-orcs, although he has a relatively strong recovery ability, but he almost has to take off several layers of skin, so he hurriedly ran to Cao Rui's side and protected himself through the protective stance of the demon mica.

After this storm, a large hall that looked extremely golden appeared in front of it. The middle light flickered, surrounded by purple and black flares, and this week there were a few other obelisks connected to the middle, which looked extremely high-spec.

"This can't be the Temple of Hades." Cao Rui has seen some related things, so he made some guesses.

But the orc quickly shook his head: "Although the Hades Temple is called a temple, in fact, his area is about the same size as a city, this is just a separate palace, although it looks quite gorgeous, it should not be the Hades Temple.

Anyway, he's come this far, so let's go ahead and see if there's anything in front of him."

The two of them then walked towards the huge palace in front of them, the doors of the palace were open, and some of the surrounding buildings were in a very bad state, as if the tiles had fallen, and the surrounding walls had large cracks.

This phenomenon is not remarkable, but at least it proves that the palace has existed for a considerable period of time, because these damages are not caused by external forces, but by natural destruction due to the loss of time.

Walking into the palace, something even more strange appeared, and something similar to the undead appeared around it, but these things were ethereal, without any hostility, and it felt like some dust floating in the air.

The interior of the palace is very obvious, there is a meeting hall in the center, a resting room on both sides of the side, and there even seems to be a special pantry, and there is also a bathing place.

And then

Further down, there are a number of higher-spec rooms, and there are quite a few of them, each of which seems to be different.

Some of the things inside also look very different from the real world.

Seeing this, the orc couldn't help but observe it carefully, and combined with the information he had learned before, he said, "Although I don't know what this thing is, it should be a temple in terms of specifications.

As for the type of temple, it is difficult to judge, from the top, it should be a place of worship, and the specifications below should also be a relatively important building in the underworld."

The first floor was basically finished, and when I came to the second floor, I found a large collection of books. It's a pity that most of these books in front of me have been dilapidated to varying degrees with the passage of time.

For example, a good book looks very complete on the cover, but when you open the contents of the book, the paper flutters everywhere like dust.

Of course, there are even more exaggerated levels of damage, such as a bookshelf, which seems to be full of books from a distance, but when you look closely, you find that it seems to have been gnawed by insects, and all the books are already broken from the outside.

When Cao Rui saw the scene in front of him, he felt a little uncomfortable: "Alas, how can I say it, if these contents can be preserved well, maybe they will still be useful to us.

There is such a sheer volume of books, and there are all indications that no one else has ever visited. Let's leave these books untouched, and see if there's a way to read them without destroying them directly, and I think the way out of here should be hidden in them."

The orc felt the same way, because this level of book collection proved that he basically recorded some important things from the ancient underworld.

Just as the two of them were observing the huge library in different directions, there were footsteps behind them.

The footsteps were heard far away, as if they were walking slowly in the direction of the passage. Because the place was so quiet, they could hear it clearly, even if they were in the palace.

Cao Rui and the half-orcs reacted immediately, and immediately found a hidden place to hide.
