For some reason, when Zhuge Yun entered here, he always had a feeling that there was something waiting for him in front of him.

That thing, perhaps, was guiding him and welcoming him from the moment he set foot on this place.

He knew very well what kind of civilization was the relics created here, but why was it shown to him in the illusion?

And that consciousness was constantly guiding him. However, he had no idea why he had come here, and what was the thing that guided him.

From the changing halo of the streamer around him, he felt a kind of breath.

The breath is in the air, in the black stones, in the faint blue light...... and, among all the things that exist here.

The place seemed to breathe, he could feel it.

"Heavenly Mountain," the name popped into his mind.

Involuntarily, Zhuge Yun's pace slowed down until he came to a standstill. The scene he had seen many times before came back to his mind, but at this moment, the depths of his soul were still trembling.

His soul seemed to have left his body, and a soft light was in front of him. It was as if someone had gently opened the crack in the darkness and was looking at him.

"Dr. Zhuge what's wrong with you, are you okay?" Su Qingyu looked a little strange when he saw him.

He suddenly fell to one knee, his head and neck extended, and looked up in one direction.

"They...... Why did you leave this thing behind...... Give me? Or is it ...... other humans," Zhuge Yun muttered to himself in his mouth.

"Hey! What are you muttering about? Qi Lin caught up and was slightly surprised to see his appearance.

Half of the young man's face was illuminated by a flickering blue light, the heavenly light that came out of the black crystal.

Su Qingyu saw that his face was transparent, as if the blood under his skin had disappeared at this moment.

The scene in Zhuge Yun's mind was still changing.

He saw the black holy city, towering over a green earth, and he saw the formation of a desert - an oasis one moment before, and the next it was illuminated by the light of the sky, and everything on the earth was reduced to dust, except for the black holy city. He saw countless flying black dust, rising from the horizon and speeding towards the Holy City. When I got closer, I realized that it was countless elytra creatures, hundreds of millions.

Where is this place?

Zhuge Yun searched his memory with all his might, trying to find out where that place was.

Desert...... Such a vast desert was formed in an instant? What kind of power is that?

What did the sudden vision show him?

And what are those elytra?

Zhuge Yun's eyes returned to normal, and he saw Su Qingyu and Qi Lin looking at him suspiciously.

He regained his senses, and looked at the space in sight, could those black holy cities be here now?

"What's wrong with you? It looked scary just now! Su Qingyu asked him with concern, stretched out a hand, and slowly pulled him up from the ground.

There were fine beads of sweat on his forehead, and his mind was still immersed in what he had just seen.

Zhuge Yun glanced up at Su Qingyu, his eyes were blank and he shook his head, as if he wanted to get rid of the terrible thoughts in his mind.

"I've just never seen ...... Forget it, it's nothing, let's go. He said lightly.

Su Qingyu and Qi Lin didn't know what he had just seen, anyway, this place was already very strange, even if they encountered anything surprising, they wouldn't be as shocked as when they first came in.

Su Qingyu looked at the watch on his wrist, there was a set time on it - they needed to leave here before that, and there were still 3 hours left.

According to the Brain Measurements, they were already 15.4 kilometers away from the place where they came in, and they had only traveled 32 minutes.

The three of them continued to walk, the geometry of the black crystal here was more detailed and more shattered—its area was much smaller than before.

The place that seemed to have no road suddenly became enlightened after the three of them became more and more proficient in "climbing".

After passing through countless huge inverted spaces, an incomparably wide "street" appears in front of you. Compared to the roads that have been walked, this is clearly a main road.

They have been observing the changes in the road since they came in, and they have a more and clearer understanding of the changes in this complex structure.

"Zhuge Yun, do you know where you are going? Do we have a purpose in doing this? Qi Lin asked.

"Yes, I don't think it's far from us, you see, those places where there is light seem to be changing shape in one direction."

Qi Lin looked in the direction he was pointing, but he couldn't see any change for a while.

"What's changed? How I can't see it. ”

"Look at those black geometric shapes. The narrow side stretches upwards, like all the signs point in one direction? ”

"Oh...... That's what you mean! ”

Qi Lin narrowed his eyes and looked at those thin blue lines, which seemed to really point in one direction.

After they followed the instructions and "jumped" for a while, the blue light began to become very faint and faint, and all the geometric building materials unfolded in the same direction under the change of light.

The speed of the march was very fast, and several people had already mastered the trick of this way of running and jumping, and they did not feel tired at all.

In fact, because the change in gravity was aiding the action, they didn't even sweat.

"Wow! Look, what is that? Su Qingyu suddenly exclaimed after jumping on the "road" that was oblique upward.

All three looked up at the same time, staring at something in mid-air.

An incomparably large black shadow hung over the black city, like an irregular polyhedral structure. Visually, the diameter of this thing is about 3-5 kilometers, and it is dotted with thin blue lines, like a small moon reflecting on their heads.

"Oh my God! It's huge! Qi Lin raised his chin and sighed as he stared at the object in mid-air.

"That's the heart of their great city, isn't it?" Zhuge Yun had no impression of such a thing, and those dreamlike scenes did not show him this.

However, Zhuge Yun also knew intuitively that that was where they were going.

Su Qingyu looked left and right, and there was no place to go up there, so he wondered: "Shall we go up there and have a look?" However, it seems that there is no way out. ”

"Let's go, let's find it. If you come here, you will be safe, and there is nothing to be afraid of. ”

After speaking, it was Zhuge Yun who stepped out first, and the distance was nearly 15 meters in one jump.

The three of them were now finally standing beneath the massive polyhedron, each nearly a hundred meters apart, and began a carpet search along the walls and ground.

Suddenly, Zhuge Yun saw that there was something different at his feet, compared to the previous dark crystal materials, the ground here was a little reflective, revealing a trace of starlight.

He crouched down and took a closer look. It is a polygonal ground with a diameter of about 5-6 meters, with smooth edges, and there is no gap at all.

Zhuge Yun's foot stepped lightly and tried, "Hum! "A feeling as if I had just entered the door hit again, and the pores of my whole body were washed by some force field.

He was overjoyed, knowing that this was the way to the top.

"I found it! Come over to me! He shouted at the other two, but was quickly stunned halfway through.

Because, he can't hear his own voice at all!
