Call!

The sound of the wind whistled past Luen's ears, and the surrounding environment jumped sharply, from light to dim, until it fell into complete darkness.

As if falling into a cloud of thick ink, Lu En estimated that according to the speed of the black dragon's swooping, he had dropped at least two thousand meters, but in his induction, he still did not perceive the bottom, but the rock walls on both sides seemed to be inhabited by many creatures, and they were alarmed and flew out one after another.

Of course, in the face of the huge and indestructible black dragon, these creatures that appeared were like eggs crashing into a stone in the next moment, directly shattering their bones, without causing the slightest trouble to their progress.

And more kinds of creatures, as soon as they reacted, the black dragon was already roaring by, and it was simply unstoppable!

Of course, from another angle, a place where there is no grass all around, and the rock walls are all bare, and there are many kinds of creatures living there, is a very strange thing in itself.

Two thousand meters!

Three thousand meters!

Still didn't see the end, but seemed to feel the movement above, and in the rock wall below the black dragon, a worm similar to an earthworm suddenly drilled out, and its body crossed the canyon on both sides, trying to intercept the black dragon.

Rumble!

However, it underestimated the speed of the black dragon's fall and the bonus of its huge size under the action of gravity, and the black dragon only lowered its head slightly, and the giant worm broke into two, and the slurry splashed everywhere, and fell from mid-air with the black dragon.

4,000 meters!

At this depth, his eyesight was completely useless, and Lu En could only rely on the induction in his mind to judge the surrounding terrain, and suddenly, he stepped on the black dragon's head and shouted:

"Stop!"

Bang!

With its head down and tail facing upward, the black dragon like a sharp arrow instantly unfurled its huge dragon wings clinging to its back, and at the same time, its body was violently lifted upward, and the bones of its body immediately let out a series of creaking sounds, and at the same time, dense cracks appeared in the muscles and skin on the surface of the body.

However, no blood flowed out of the wound, but after the wound appeared, it disappeared and healed completely in less than two seconds.

If you change to any creature and do such an operation, the final result will definitely be broken bones and there will be no place to bury, but for the black dragon, this is completely acceptable, and even if it does not slow down and fall headlong, it may not really fall.

Of course, Lu En, who was standing on the head of the black dragon, would definitely not be able to withstand this kind of impact at this time.

Whoa!

The hurricane carried by the huge dragon wings fanned out everything around it, emitting a series of fragmentary sounds, and then spreading into the distance, while the black dragon slowed down and slowly declined, and finally stepped on the hard ground with a bang.

Four thousand nine hundred meters!

This is the final depth of the canyon in the Luen induction, which is almost equivalent to the moat for the vast majority of human beings, especially the humans of this world, and even ordinary people at this depth, it will be difficult to breathe.

Syllable!

Lu En snapped his fingers lightly, and a blood-colored ball of light suddenly appeared, illuminating the surrounding environment.

Overall, it was no different from the above, there was no grass, and the ground was covered with a layer of sharp and solid gravel, but on top of these rubble, Lu En found some traces of large biological activity.

For example, a slime-stained sliding passage, Lu En moved his mind and manipulated the ball of light to move forward, only to find dense black holes in the rock wall, some of which were large and some small, the smallest could only accommodate one finger, but the largest, even the black dragon could barely squeeze into it.

And judging by the friction marks on some of the holes, it is clear that some of them are often used.

"If the blood mage's base camp is in this kind of place, even if it is a necromancer, there is no good way to take them!"

After Lu En took in the surrounding environment, he couldn't help but nod secretly, this kind of naturally formed dangerous place can greatly offset the numerical advantage of necromancers, not to mention that there are countless creatures living around the rock wall, it is simply as many as they come, how many people die, kill and bury.

"Keep going!"

Lu En gave an order to the black dragon, the undead creatures usually have dark vision, and the darkness around them is nothing to the black dragon, but perhaps because it senses the danger in the dark, it has begun to act cautiously.

The huge claws trampled on the gravel, making a creaking sound, and the black dragon supported Luen to start moving in one direction, and after descending to the bottom of the valley, Luen's sense gradually became clear, and he could detect the secret attraction of a certain area to him.

This is the mutual induction between the fragments of authority, but this induction is bidirectional, which means that when Luen can sense the other party, the other party can also sense Luen's existence.

Surprisingly along the way, it was calm.

Lu En could sense that there were countless pairs of covetous eyes in the darkness, but the owners of these eyes never appeared or attacked him, but allowed the black dragon to advance with great momentum.

It didn't take long for Luen to see a building nestled in darkness on the raised rock at the bottom of the canyon, slowly revealing its true face.

The structural style of these buildings is very different from what Luen has seen in this world, with tall column-like structures and soft arches, giving people a sense of epic shock.

It's just that as he got closer, Lu En found that although these buildings were brilliant, they were also extremely dilapidated, almost none of them were intact, and some of the collapsed columns were almost comparable to the black dragon, which showed how brilliant this building complex should have been during the complete period.

And Lune only took a few careful glances before coming to a conclusion.

This is definitely not something that can be built by the humans of this world!

Not to mention the structure and style, just at the bottom of this canyon that is close to five thousand meters, it is absolutely impossible to carry out such a huge project, according to the scientific and technological level of this world, even if the necromancer and the blood mage are combined.

Of course, the more obvious feature is that the traces of the dilapidated buildings are obviously more than 1,000 years old, and some areas are severely weathered and are about to disappear completely.

"Roar!"

Suddenly, the walking black dragon stopped, roared from his throat, and arched his back.

This was a sign that the black dragon felt threatened, because right in front of it, three humans dressed in gorgeous robes appeared, one man and two women, all of whom were handsome men and beautiful women, except for those with white skin.

"O foreign gods, my lord has already met your arrival!"

Seeing that the black dragon stopped, the man standing at the front walked out and said in an aria tone: "Come with us, what you want to know, what you want, my lord has prepared it for you." ”

"Your arrival in this world was not an accident, but a complete arrangement of fate!"
