Tianyan glanced at the empty square ahead, "I saw a battle, a battle that could not be avoided. But don't worry, we can easily win. ”

Xing Tianyu nodded, and walked towards the ancient city in front of him.

The others followed, and the group stepped onto the barren red plain, illuminated by the crimson light overhead, towards the massive city in front of them, and behind them, the low building where the teleportation array hall was located was gradually left behind.

The further they went, the more clearly a few people could feel that an inexplicable will, a sense of existence that could not be ignored, was lying in front of everyone, making several people feel inexplicably uneasy in their hearts. It's like a human child walking towards a sleeping beast. Even if you don't see the beast for what it really is, just hearing its breathing and smelling the stench coming from it is enough to make people nervous.

This pressure is not only internal, but also reflected in reality. The prediction and detection effects of magic and abilities have been distorted to varying degrees, so that the effects of the positioning technique used by Sylvia appear and disappear, and the reconnaissance magic cannot be used.

Only the eyes of the eye of heaven are still clear and bright.

Several people were in a state of vigilance, Xing Tianyu released the spirit body in the crystal ball, and Sylvia used magic to transform more than a dozen magic hounds, they are translucent canine-like creatures composed of arcane energy, and their combat power is similar to that of a large hunting dog, this combat power is naturally meaningless in this kind of dangerous place, but because their bodies are lighter, their speed is abnormally fast, and their ears and eyes are clear, they are extremely effective means of investigation.

Not to be outdone, the Blood Duke used blood magic to conjure up more than a dozen red bats, and these chaotic scouts spread out in all directions, scouting the surrounding environment and ensuring the safety of the team.

The group had not advanced more than a thousand meters before a magical hound suddenly stopped, as if it had discovered something. "Wangwang." It let out a vigilant roar, its magical body amplifying its volume, and in the empty and silent square, it was surprisingly piercing.

"Be careful, everyone, there's something nearby." Sylvia said.

At this moment another hound howled, and its howl was immediately answered, and suddenly a large crimson claw stretched out from a pile of abandoned rocks, and at once it caught the magic hound. The body made of an extremely small amount of arcane energy was unusually fragile, and instantly turned into scattered light, and immediately after, a huge monster emerged from the pile of rocks.

It looked like a spider-crab cross, with eight opposing thin legs, a spiky rock-like carapace, and a pair of giant chelae. It was four or five meters long, and it rushed out in a rampage.

"It's unbelievable that there are living creatures here." Franken let out an exclamation, "If you have the chance, you must study it." ”

However, others didn't have this kind of leisure, Sylvia directly burst the ice, and a white ball of light the size of a basin was released by her, hitting the body of the giant crab, and the frost energy in the ball of light gushed out, instantly freezing it in place, and then Sylvia made up for it with a bolt of light, and with a bang, the huge body made of rocks that seemed to be indestructible suddenly split apart and shattered.

"Well done!" Tianyan let out a sigh of admiration.

However, before the shouting was over, more crabs emerged from the rocks beneath the ground around them. The seemingly flat and lifeless crimson plain was beyond everyone's expectations that there were so many strange creatures hidden. However, in the face of the rock giant crabs surrounded from all directions, everyone was not too nervous.

Although those giant crabs seem to be very strong, and there are a lot of them, if they are ordinary people, it is estimated that they will only run away in despair, but among the people present, who is an ordinary person? Sylvia's magic is cathartic, since she has strengthened the blood of magic elves, she no longer has to worry about the symptoms of magic addiction or anything, this magic is naturally unscrupulous to use, and for this operation, she has prepared enough arcane essence and magic potion, which will be thrown out like magic without money, and those cancers are killed by her one by one.

Lucifer also summoned several powerful demons, tearing apart the bodies of these monsters in the same way.

The Blood Duke also began to use blood magic, but unfortunately it didn't seem to have any effect on these rock monsters, and after he tried a few times and found it useless, he could only hide to the side and watch the excitement.

Franconian dismantled the crabs with his bare hands without any pressure, his mutated body was infinitely powerful, and the scale armor on his body was even more invulnerable, like a biochemical monster.

Sky Eye and Sleepless are basically not doing much.

In less than five minutes, the rock crabs were killed, leaving only a fragment of rock.

"Seems simple." Xing Tianyu cut the last rock giant crab in half with a sword, but he had a little more confidence in Tianyan's eyes.

At this moment, the earth suddenly trembled again, and more rock cancers came out, not only that, but there were also some strange creatures made of rocks, some of which were more than ten meters high, and some of which were like centipedes, with strange arthropodes-like bodies.

Despite their different appearances, they all have the same characteristic, which is that they look like some kind of rocky, crystallized appearance.

Seeing that dense monsters were coming from all directions, Sylvia was about to enlarge the move, but Xing Tianyu grabbed her hand. "Don't waste time here, we have to save our strength, come with me." As he spoke, he led the way towards the huge city in the distance, and the crowd hurried to follow. Sylvia released the power of a blast at the right time, and everyone suddenly felt as light as a swallow, the soles of their feet were windy, and their speed was more than doubled, and in the blink of an eye, a group of people rushed into the gate of the city. The rock creatures rushed out of the gate, but as if they were afraid of something, they stopped, and they all returned to their original positions, turning into piles of rocks.

"These creatures all look like ancient creatures, and I think they must be some kind of artifact, perhaps a defense of the Sakadum, like robots." The Sleepless Man seems to be talking to himself, and as if he is presenting his own opinion.

"It makes sense, but if that's the case, then the Nightmare King in the city is already prepared." Xing Tianyu said as he glanced around, where they were, one of the entrances to this underground ancient city, an empty hall-like place, and around the hall there were several paths leading in different directions.

And in front of them, directly opposite the entrance to the gate, stood a huge statue of the Sakadum people, a spherical creature with a huge one-eyed creature staring at them as if it were a living thing.

In front of the statue, there was a stone platform, on which everyone saw some strange stone slabs with strange rune-like things painted on them, which were very similar to what he saw on the teleportation array, and next to the runes, everyone also found a psionic crystal, which was inlaid in the center of the stone slab.

Xing Tianyu recognized the words.

It reads - the city of Rafatian: the refuge of the Sakadum

"This is supposed to be some kind of Sakadum device, and it should be activated with psionic energy." Xing Tianyu said.

The reason why he said this is because he has discovered that in the eyes of the Sakadom people, it seems that the use of psionic energy is as wide as electricity in human society, which is not difficult to understand, after all, the Sakadom people are born psionic mages, and it is natural to develop related technologies.

Xing Tianyu tried to inject some spiritual energy into the spiritual energy crystal on the stone slab, and a white three-dimensional map was immediately projected on the stone slab.

This three-dimensional image, which is two or three meters in diameter and suspended in the air, is a perspective view of a city.

"It's a three-dimensional model of the city." Sylvia said in surprise as she pointed to a red dot on the edge of the city, "This should be where we are." She pointed to a large, shadow-covered space in the center of the city, "This must be where the Nightmare King is." ”

Xing Tianyu nodded, "It's very likely, let's try not to contact him, so it's easy." It seems that there are a lot of such devices in this city, which can be activated with psionic energy, so which of you can use psionic energy? ”

"I'll do a little." Tianyan raised his hand, "Barely a mid-level psionic mage." ”

"I'll do a little too." The Sleepless said.

Xing Tianyu said in his heart that three of the seven people knew psionic magic, which was very convenient. "Very well, then let's move on." A few people chose a path and began to move forward, still explored by the Blood Duke's bats and Sylvia's magical hounds. Led by Lucifer's demons, the group marched down the winding passage into the depths of the city.

The architectural style of the Sakadom people is very peculiar, the passage is not boxy, but circular, like a huge pipe, and circular holes can be seen in the surrounding walls from time to time, leading to nowhere, there are no stairs in this underground city, the path up or down is the entire slope, in addition to many shaft-like things to communicate the upper and lower levels, this is probably due to the fact that the Sakadum people have no legs and feet, and they are spherical. Plus they can float in the air with psionic energy, that's why they were built into this shape.

But when humans walk inside, they have a very strange feeling, as if they are walking inside the body of a huge monster.

There were many forks in the road they were traveling, leading to different rooms, halls, and warehouses and the like, but after a few brief reconnaissance of those places, they found that there was nothing there.

It seems that the city was not put into service.

The group did not stray far from the main route.

And the city is not only weird, but also very quiet, the size of the city is very large, presumably as a refuge to accommodate a large number of people, but now it is empty, all the way, all around, there is no sound.

The thought that he might be the first human to walk into the city in millions of years made Xing Tianyu feel excited and uneasy.

Walking and walking, Xing Tianyu suddenly chirped under his feet, the originally dry and solid road surface, I don't know when some mucus-like things appeared, he looked around, the traces of mucus were not obvious, but it was like silk meridians, growing everywhere, even on the surrounding walls, some were purple like mud, and some were red like blood vessels.

"What the hell is this?"

"I don't know, but I don't think it's going to be a good thing." Tianyan pulled a red vein from the wall and looked at it, and a trace of solemnity flashed in his eyes.

"What do you see?"

"I see a terrible existence, this is not something on Earth, I'm afraid there will be a battle waiting for us."

Francon, on the other hand, tore off a piece of red vein-like thing, looked at it for a while, and suddenly put it in his mouth and chewed it.

"It's the nervous system of some kind of creature." He said, "Don't worry, I have a way to deal with this." ”

A few people continued to move forward, there were more and more traces on the wall, and there was more and more slime on the ground, and even Xing Tianyu noticed that there were some flesh buds like ferns, hanging upside down on the wall.

"Oh my God, what's that!?" The Blood Duke suddenly exclaimed.

Everyone looked in the direction he had indicated, and between the walls there was a bud of flesh extending from the gap, and a yellow eyeball the size of a pigeon's egg grew on the top of the bud, and was motionless at the top of the bud.

The granes were attached to the red veins, and they seemed to be part of these things.

As soon as Xing Tianyu raised his hand, he shattered the eye with spiritual energy, but soon he found that it seemed to be in vain, those things like blood vessels seemed to be all over the area, forming a huge network of things, and this kind of eye also grew everywhere, from all corners, between the gaps, on the top of the head, under the soles of the feet, watching their arrival everywhere, obviously, their whereabouts had been exposed.

"These things, I don't think it's in the style of the Sakadum people." Walking and walking, Xing Tianyu suddenly said.

Although the Sakadom people themselves are also very strange, whether it is the scenes Xing Tianyu saw in his dreams in the past, or the ancient memories he obtained when learning the Sakadom script, and the feeling that this strange city gave him, the Sakadum people are highly intelligent creatures, with powerful psionic powers, and very advanced technology, giving people the feeling of being more like an alien in the style of mysticism.

And the slime in front of me, the red blood vessels on the wall, and those weird organs growing everywhere give people the feeling of evil biochemical monsters, and the styles of the two are completely incompatible.

Coupled with the fact that the city was empty, Xing Tianyu felt that something must have happened in the city.

Xing Tianyu had a faint feeling that perhaps the reason behind this was the reason why the Nightmare King had lived for millions of years, and the reason why he was able to survive from the ancient times must have undergone some kind of mutation, making him an out-and-out outlier among the Sakadum.
