They don't seem to have sight, but they have a very good sense of hearing, and once they make a sound, they can detect it. The knowledge that appeared in the depths of his consciousness made Zhuo Lei's heart full of surprise, and he couldn't imagine that even this Yin soldier had it.

Knowing the danger of the ancient ghost, he didn't dare to be careless, and even the sound of breathing deliberately slowed down a lot.

Master Ulla's steps were light, but not slow, and everyone followed closely.

Walking in the fog, although Zhuo Lei's senses were keen, after half an hour, he also found that he had lost his ability to judge the direction of his surroundings, and he could not distinguish between east, east, west, and north.

Fortunately, Master Ulla walked in front of him, so he didn't feel worried.

Thinking that there is something he needs in Jade City, otherwise he will never be keen to shoulder this responsibility, it can be seen from the fact that he did not save Gangzi before, and Master Ula is not a good stubble.

The ancient ghosts in front of them kept flashing, and they should have been transformed by the spirits of humans who died in this place, and most of their appearances were the same as when they were alive.

In less than half an hour, Zhuo Lei and the others had discovered at least seven or eight regional faces.

In addition to the common face shape of the plateau, there are also standard Central Plains people's appearance, most of them, but there are also people from the South Asian subcontinent with brown and black skin, and there are also people from Central Asia and West Asia with towering cheekbones, which surprised everyone and gave them a little more understanding of Yucheng.

It can be seen from these ancient figures that Yucheng is not only a stage for the Central Plains and plateau people, but also has a certain degree of radiation in Central Asia, South Asia and other regions, and has a wide range of influences.

Of course, Zhuo Lei can imagine more, Bon is not only a sect unique to the plateau, in Central Asia and West Asia, it has also been spread, not to mention, Tibetan Buddhism, which has inherited many religious rituals of Bon, has many rituals similar to the sacrificial methods of some estimated ancient religions in Central Asia and West Asia, such as Zoroastrianism.

From these faces, he couldn't help but think of some legends about the Guge Dynasty, the former owner of the Jade City. It is said that at the height of the Guge Dynasty, its territory once reached Central Asia and West Asia.

The state religion of the Guge or Zhangzhung Dynasty was Bon, so it is possible that the power of Bon once reached West Asia. This would not only explain the presence of these foreign faces in the Jade City, but also why Tibetan Buddhism and other religions have similar rituals.

After about an hour or so, the surrounding fog gradually dispersed, and those ancient shadows began to dissipate into invisibility, and Master Ula waved his hand to stop Zhuo Lei and the others.

"When you encounter the Ancient Phantom Yin Soldier, don't speak." Master Ulla breathed a sigh of relief and said gently, "Here, although their attack power is not strong, it is difficult, and if they are branded, it will be very troublesome.

Zhuo Lei nodded yes, listening to his words, some incomprehensible meanings of terms quickly appeared in his mind.

The so-called brand of ancient charms is actually infected by the breath of ancient charms, as long as they are looked at by these ancient charms, then they will firmly remember this person, as long as they are located, they can be found at any time.

And what surprised Zhuo Lei was that the ancient ghosts were only outside the Jade City, and they were a pure spiritual force, while in the Jade City, they were no different from ordinary people, the only difference from humans was that they did not have the same thinking ability as humans, but they were more destructive than humans.

Suddenly, his heart sank, and after a while, he let out a faint breath of turbidity, and said with some concern: "There is trouble, Muge and I seem to have been branded by them." ”

He suddenly remembered that he had accidentally said a word to Mu Ge before, and he was glanced at by that group of ancient charms, and a chill flashed down his spine.

Master Ulla was slightly stunned, and motioned for Zorley to stretch out his left arm, rubbing it vigorously, and after a while, a pale gray circle appeared on his arm.

But when it came to Muge, it was gone, and I thought that Gu Mei had already left the scope of branding.

"Be careful yourself, don't be three steps away from me". Marked with the mark of the ancient charm, even Ulla is helpless.

After completing the instructions, he led him to the interior of the jade city.

From the first step in Jade City, Zhuo Lei was full of curiosity about the internal structure of Jade City.

If it weren't for the fact that he had a more important goal, at the first layer, he would have prepared to enter the inside of the jade city to see what it looked like inside this miraculous jade city.

All kinds of speculation and speculation about Yucheng in my heart are better than seeing it with my own eyes after all. The light of the flashlight shone on the jade wall, reflecting the glittering brilliance, and everyone couldn't help but take a deep breath when they looked around.

The construction process of the stone cave on the stone wall is enough to amaze them. But compared to this jade city, the caves on the stone wall can only be regarded as mud piles made up of mud and sand for children to play with.

This jade city is like a work of art carefully carved by a master sculptor.

Between the two, there is no existence between the same order at all.

The interior of the Jade City was developed and utilized as much as possible, but the excavators sought to follow the principles of building mechanics in every inch of the building, ensuring that the interior of the Jade City was as spacious and safe as possible.

At a glance, there are dozens of huge jade pillars staggered out, firmly supporting the entire space. There are also extremely exquisite reliefs on the jade pillar, not only on the jade pillar, but also on the surrounding jade bib and the dome, there is no lack of magnificent and magnificent patterns.

This is only the entrance to the original space, and the inside that is not visible at a glance is a criss-crossing tunnel, and the intersection is deep and dark, but there are bursts of convection making a "whirring" sound, which is obviously ventilated.

Unfortunately, it has also been affected by the fighting, and the traces of the fighting are even more visible. Many of the reliefs on the jade pillars have been destroyed, and in some places, there are signs of smoke and fire, and the bones on the ground are also all over the ground.

"Damn!" Mu Ge walked in front of a jade pillar and saw the relief on it that had been smashed by a blunt object, and gritted his teeth and held back a sentence.

The role of this relief is unknown, but at least two-thirds of the way has been hammered, and only the part near the dome has been preserved.

However, the ground is at least twenty meters away from the dome, and even with his deformed eyesight, it is difficult to see clearly what is engraved on it, because when the flashlight shines on it, the jade on it will reflect and diffuse the light, covering up a lot of the image of the relief, making it difficult to identify.

After looking at several jade pillars in a row, they all had the same result, and Mu Ge's face became more and more ugly.

However, Zhuo Lei found some clues in these damaged reliefs, and his face became a little strange, and after a while, he slowly said: "Have you found it, these reliefs have been completely destroyed, no, it should be said that they were destroyed very carefully......

Master Ulla looked at it and nodded slightly. He frowned and said, "Yes, the contents on these jade pillars are likely to have been destroyed by the guardians of the Jade City back then. ”

"Why would they do this?" Zhuo Lei was a little confused.

"To keep it a secret." With Ula's affirmation, his train of thought instantly became clear.

The contents of the jade pillar should be relatively important information, and the defenders are worried that these secrets will fall into the hands of the enemy, and at a critical moment, they will definitely think of destroying these secrets. Like the revolutionaries in the TV series, after being targeted by the spies, he quickly burned the important documents at hand and said ......"

After carefully identifying it, the information record on the jade pillar was indeed destroyed on a large scale and planned.

"What can I do?" Mu Ge scratched his head and said, "The jade city is so big, some important information recorded on the jade pillar has been destroyed, and we are very passive."

Hearing this, Master Ula's voice was not impatient, and he said indifferently: "Explore layer by layer, and there will always be gains from the bottom up."

If his prediction was right, the White City in front of him was the Zhangxiong Ancient Kingdom, and the useful materials in it had been destroyed, and the Guge Dynasty, which was born after a thousand years, was obviously more prosperous, and he only hoped to leave something useful for it.

Zhuo Lei was shocked in his heart, although he didn't know how many layers the Jade City had, but he knew how high the Jade City was, and Master Ula actually searched layer by layer, and he didn't know how long it took to complete such a huge project.

The crowd walked through the criss-crossed dark tunnels, it was like a labyrinth, it took several days, they only reached the second floor of the Jade City, according to Zhuo Lei's estimate, the Jade City was at least between the thirteenth and fifteenth floors, and if this continued, food and fresh water would become a dilemma they would definitely face.

"Cluck, cluck......" A slight but neat sound came from the passages on the left and right sides. Hearing this voice, Zhuo Lei immediately became vigilant, and Master Ulla's voice sank even more, and said, "Get out of here!" ”

As he spoke, he walked quickly towards the jade path on the side.

Yushan pushed Zhuo Lei forward, and he quickly followed.

"Roar ......" A deep roar suddenly made noise in the surrounding passages, and a loud voice came from the depths of Zhuo Lei's consciousness at this time: "Any blasphemous person who dares to set foot in the Holy Land will eventually become the guardian puppet of the Jade City!" ”

The sound was like a burst of thunder, slamming into the depths of Zhuo Lei's consciousness.

He suddenly felt a heart-pounding pain in his skull! There was also a hint of sweetness in his throat.

With a shake of his body, he almost fell to the ground. I was horrified, this strange and inexplicable voice just appeared in his consciousness, and it caused him such a serious trauma.

What exactly is this sound?

However, after Ula's hand took his arm, there was a faint warmth immediately, which eliminated all the discomfort on his body, and the thunderous loud sound was also cut off at once.

At this time, the light emitted from the surrounding jade was much dimmer, but the noisy "rattling" sound around was getting closer and closer.
