The white-robed guest stood in front of the isolation suit, looking at the broken shield with only a corner on the ground, took a deep breath, reached out to grab the edge of the shield, and then lifted it up with force.

It can be seen that the broken shield is stuck tightly under the ground, and it is a white-robed guest, so he can pull out the shield bit by bit.

With the movement of the white-robed guest, the appearance of the shield slowly appeared in front of several people. The shield was made of bronze and covered with a lot of copper rust on the surface. Under the copper rust, there were scratches after scratches. Obviously, the shield had collided with a sharp weapon.

Gradually, the entire shield was pulled out of the ground by the white-robed guest. The shield was diamond-shaped, about 60 cm high. In addition to a missing corner above, two other places below were destroyed.

Before the white-robed guest and others could carefully study the shield, the entire underground passage seemed to have been triggered, and suddenly began to shake violently.

Everyone standing in the pit could clearly feel that the ground under their feet was shaking violently and collapsed.

The man standing in front of Xiao Yang and wearing casual clothes subconsciously glanced at his feet, but as soon as he lowered his head, his feet were empty and his whole body fell to his feet.

The same is true for Xiao Yang and others. The ground under their feet was cracked almost at the same time.

After falling for a while, all of them fell to the ground, but the ground was not flat, but a downward slope, allowing the people who fell on it to continue sliding downward without control.

Xiao Yang and the White-robed Guest adjusted their figures as soon as possible. As long as they were willing, they could stop their decline at any time. However, neither of them did this. After all, the purpose of this time was to see what was in the No. 4 underground palace.

Everyone fell in a hurry, and the lighting equipment on their bodies was not fully turned on. They only had two strong flashlights. Because the continuous rotation made the light like a windmill under the strong wind, the light source could not provide everyone with good lighting. It was pitch black below the tunnel, and even the white-robed guest and Xiao Yang could not clearly see the scene in front of him under such high-speed movement.

This sliding lasted for nearly a minute before stopping. Except for Xiao Yang and Baipaoke, the other five younger generations in the Ninth Bureau all fell to the ground. Fortunately, three of them were protected by isolation suits. The material of this isolation suit was good and would not be covered in dust. The man and woman in casual clothes looked much embarrassed.

Xiao Yang silently calculated the distance in his mind. They slid down from above to now, and dropped by at least two hundred meters.

It sounds like two hundred meters underground, but it seems nothing, but this is a forbidden area that 99% of the world have never touched.

When Xiao Yang completely stopped, he began to look around. His eyes gradually adapted to the darkness in the pit and could see some blurry scenes.

Xiao Yang looked around and found that the pit was particularly vast, just like when he was on the top of the eighteenth level of hell, with no edges around him and no sky looking up.

"This...this is too big!"

Xiao Yang heard the sound that seemed a little shocked from the headset.

“Where is the place below this?”

Two lights suddenly lit up. These were two lighting flashlights being turned on. The light brought by the flashlight allowed everyone to see the scenes around. Seeing this, not only the five younger generations in the Ninth Bureau, but even Xiao Yang and the white-robed guest couldn't help but open their mouths, looking like they were seeing ghosts.

Around them is a vast flat land, and outside the vast flat land is layer upon layer of black stone roofs.

"We are now, as if we are standing on an altar." A man in a quarantine suit swallowed his saliva.

"We are standing on the altar." The white-robed guest spoke, admitting this statement.

At this moment, the place where everyone stood was the ancient altar used to sacrifice to heaven. The altar was very large, comparable to a football field. Seventeen meters in front of Xiao Yang, a staircase with less than two people walking straight down. If you count it down, there were hundreds of stairs. Apart from this staircase, there was no other road leading from below to this staircase.

Walk to the edge of the altar and look down. It is at least a few dozen meters away from the ground. There are dense black buildings around the altar.

The so-called black is not that the sun is not seen here all year round, but that the bricks and stones used in the building are black hard rocks. Every house is spire-shaped.

The appearance of this No. 4 underground palace in front of Xiao Yang and others is clearly a dungeon!

Xiao Yang turned his head and glanced around, and found that the faces of Jiuju and others, including the white-robed guest, were full of shock. Even Xiao Yang himself was shocked.

Dungeon! There is actually a dungeon a few hundred meters underground! If this news is released, I wonder how many people will be crazy!

"How could there be a dungeon here?"

"The times change and the crust movement are the original cities on the ground sinking into the ground and have been buried here?"

"What dynasty is this? Looking at the five thousand years of the ancient and modern times of the summer, there is no dynasty that has flourished this kind of tower-shaped building!"

The few people in the Ninth Bureau, each one, made these guesses as if they were talking to themselves.

"Uncle Master, do you have an impression?" Baipao Guest asked Xiao Yang using his private channel.

"No." Xiao Yang shook his head, "In my impression, I have never heard of such a city. In ancient times, it was definitely not something that could be built in a small town. At least it was first-class in the country."

"What capital is there in the northwest boundary? Which ancient Western Xia country is it?" The white-robed guest made a guess.

"No." Xiao Yang denied the speculation that the white-robed guest had dropped. "The architectural style of the capital of Xixia is not like this, and speculation is useless. Let's go and have a look."

"Yes." The white-robed guest nodded.

Several people came to the edge of the altar and looked at the hundreds of steps that were almost vertically downward. The three members of the Nine Bureau wearing isolation suits felt weak.

The staircase is so steep that there are no handrails on both sides. If you don’t pay attention, you may fall down directly.

Two members of the Ninth Bureau in casual clothes walked up the stairs first and walked downwards. The remaining three members of the Ninth Bureau in isolation clothes walked in the middle, while Xiao Yang and the white-robed guest walked at the end.

"Instructor, the test results have come out. The density of spiritual energy here has dropped to the lowest value, and there is air circulation. In addition to the entrance where we come in, there is another way out here." The man holding the tablet computer spoke.

When the white-robed guest heard this, he took off his helmet. Sure enough, his breathing was not affected at all a few hundred meters underground.
