Xiao Yang stood on the black rocky road, looking at the eighteen-meter towers in front of him, frowned and silent.

"Uncle Master, what did you find?" The white-robed guest walked to Xiao Yang and asked in a low voice.

Xiao Yang shook his head slightly, "Have you noticed that the scene here has been described in some books?"

"Book?" The white-robed guest looked puzzled. He thought for a while, then shook his head, "Uncle Master, I think I am well-read in ancient history and have never seen such a description."

"Of course not in ancient history, what I said is in the book." Xiao Yang said, "In the legend of Shushan, there is a demon-locking tower, and there is a demon-suppressing sword on the top of the tower to suppress the evil spirits in the tower."

"Uncle Master, what you are talking about is a fairy tale novel!" The white-robed guest had a speechless expression. "How can the things in the novel be put into reality? You don't think that all the monsters and monsters are locked in these towers, right?"

"The things in the novel cannot be taken seriously, but this tower is definitely something to be detained. Come with me." Xiao Yang stepped forward and walked forward.

The white-robed guest followed Xiao Yang with confusion. After walking out for dozens of meters, Xiao Yang suddenly stopped. The position he was standing at was in the center of two high towers.

"Look at this." Xiao Yang stamped his foot here and looked at the ground.

The white-robed guest's eyes followed, and a small piece of locking chain was printed into the white-robed guest's eyes.

The white-robed guest squatted down and observed the chain on the ground. The chain was less than twenty centimeters long, and one person had forearm as wide as he had broken marks on both sides. When the white-robed guest saw the broken chain, his pupils suddenly shrank, "This..."

Both sides of the chain are stretched separately and have been deformed.

"The chain was broken, not because it was cut off by a sharp weapon, but because it was pulled off." Xiao Yang said softly, "The chain is made of unknown material. Even though it has been buried here for so many years, it is still harder than steel."

The white-robed guest picked up the chain and found that the chain was particularly heavy, less than twenty centimeters long, only sixty kilograms.

"Come with me again." Xiao Yang waved his hand at the white-robed guest, then jumped up to the top of the tower.

The white-robed guest came up from behind, and the two of them had already reached the top of the tower.

"Look at this." Xiao Yang reached out to touch the spire. At the top of the spire, there was an iron ring used to bind chains. At this moment, only a small part of the chain was left. The other side of the chain, just like the one that Xiao Yang and the others found on the ground, were forcibly torn off.

Xiao Yang continued to speak, "I just observed ten towers. Each one is tied with chains, and there is a thin mark on the surface of the tower top. This is a mark formed by the chains being covered by wind and rain all year round, all facing one direction, that is to say..."

"Every spire is connected by chains!" Before Xiao Yang finished speaking, the white-robed guest answered, "It was just that the chain was forcibly torn off."

"Yes." Xiao Yang nodded.

"But what is this for?" The white-robed guest's face was even more confusing. "The chains were used to connect each spire, and the chains were torn off by someone, but the tower had not been damaged yet."

"It's better to think about another question than thinking about this." Xiao Yang stood on the top of the tower and looked into the distance. It was pitch black. Even if Xiao Yang was not sure what was there in the distance, it was like a new world.

"What?" asked the white-robed guest subconsciously.

"I just said, what happened to the chain marks on the top of the tower because of the wind and rain for many years that a city on the ground can be saved for hundreds of meters underground. I think you might as well start from this aspect instead of guessing those clues. "Xiao Yang said.

The white-robed guest's eyes lit up, "Yes, Uncle Master, why didn't I think of this? If I could figure out why this city was buried underground, I would definitely find useful clues, which is better than guessing like this."

"You didn't expect that you just saw such an unknown place and were just stubborn." Xiao Yang patted the white-robed guest on the shoulder.

The white-robed guest opened his mouth and was about to say something when he heard a burst of exclamation from below.

"careful!"

"retreat!"

The master of this exclamation came from the younger generations from the Ninth Bureau.

Xiao Yang and the white-robed guest's faces changed, and they jumped down almost at the same time. The dungeon was too mysterious, and no one knew what was here or what kind of danger was hidden here.

When Xiao Yang and the white-robed guest landed on the ground and ran a turn, they saw a member of the Ninth Bureau wearing an isolation suit flying backwards and slamming towards the ground. When he was about to fall to the ground, the white-robed guest reached out and took him down.

The white-robed guest saw that the member of the Ninth Bureau had blood on his mouth and a slender hole appeared on his isolation suit.

"What's going on!" asked the white-robed guest with a frown.

"Instructor, there is an enemy." The member of the Ninth Bureau said pale.

"Enemy?" The white-robed guest was suddenly shocked. There was actually someone else in this underground city!

"You can find a way to contact the above, I'll go and take a look first." The white-robed guest said, then turned into a phantom and rushed forward.

Xiao Yang did not immediately follow the white-robed guest. He looked at the gap in the isolation suit of the member of the Ninth Bureau. There were some copper residues on the edge of the gap.

"It's copper again?"

Xiao Yang's eyebrows frowned slightly. He always felt something was wrong. Recently, he had seen too many such things with copper chips, in the Loulan Shahai, in this No. 4 Underground Palace.

Xiao Yang observed the architectural model and materials of this dungeon. It was impossible for him to develop to such a low-end as the Bronze Age. However, the broken shield and the sharp weapon to cut through the isolation suits of the Nine Bureau members were all related to copper.

Xiao Yang walked a few steps forward and saw the figure of the white-robed guest.

At this time, the white-robed guest was attacking with the other four people in the Ninth Bureau.

The White-Board Guest is the spokesperson of the Nine Bureaus, and his strength should not be underestimated. He also studied under Bai Jiangnan. He is one of the few masters. Although he did not hold a silver spear this time, his strength was a few points worse than his heyday, but not everyone can deal with it.

But at this moment, the White-Board Guest joined forces with four members of the Ninth Bureau to deal with the shadow in front of him, but he was unable to take it down for a long time. The other party ignored the White-Board Guest's anger and frequently smashed his fists at the White-Board Guest.

"Who are you!" The white-robed guest dodged the other party's fist and shouted loudly.

Facing the white-robed guest's question, the other party seemed to have not heard it, and continued to punch, each punch hitting the fatal point on the white-robed guest's body.

Xiao Yang stood not far away, squinting his eyes at the black shadow's movements. Although the other party's movements were simple and seemingly reckless, they were all killing moves.
