The length of this road seems to be longer than originally judged. And when you get to the end, it turns out to be a spiral staircase that leads to the underground.

This staircase is still a modern cement pavement, not in pursuit of luxury, more like an underground air raid shelter, and it looks like it must be something modern. It's just that the Yiwu Society hid this thing under the huge Knight Palace, or built the Knight Palace on top of the mysterious thing below, so the purpose of deliberately hiding it is obvious.

However, the stairs of this descending passage are very narrow, and the walls are smooth, and there is no place to hide. Seeing Kronos walking down step by step, Gao Longzang could only continue to go deeper step by step. As soon as you stop, you will inevitably collide with Kronos.

Gao Longzang felt that even if he had to go out and kill him as a last resort, he had to delay enough time to get the paladin away from here as far as possible. At that time, even if there is any chaos in this knight's palace, he can't let him quickly turn back to help after receiving the news.

That old guy was already SSS-level, armed with that amazingly powerful holy spear, Gao Longzang didn't want to start fighting him on the opponent's territory right away. Even if you want to compete, you have to wait until the time and place are at least equal for both sides.

Therefore, Gao Longzang walked down step by step under the dim light next to the stone steps, always maintaining a distance of dozens of meters from Kronos. This distance is just enough to allow the spiraling staircase to block Kronos's gaze, but at the same time, it can ensure that Gao Longzang's hearing can make various judgments in time.

But just going on like this, Gao Longzang was surprised to find that he had probably descended more than 100 meters underground, and he still hadn't reached the end. So deep, what exactly is underneath!

Could it be that this knight's palace was built on an ancient relic?

As a result, when Gao Longzang descended a full 200 meters, he felt a sudden increase in the brightness of the light in front of him - it was finally over!

It was a small door, and there were some artificial noises coming from inside. Gao Longzang quietly leaned over, poked his head out of the frame of the door, and was suddenly stunned-

It's an unimaginable space!

The circular area, which is about one kilometer in diameter and more than forty or fifty meters high and more than a dozen stories high, is like a huge underground lair.

And in this space, it looks like a small city—ancient, dilapidated, lifeless...... City!

Because in it, there are some suffocating ruins of broken walls, like a deserted city in the desert, which is very ancient at first glance. The specific age of the era, Gao Longzang is naturally impossible to see through at a glance, but judging from the dilapidated Cheng dù alone, it is not ordinarily long. You must know that there is no wind and sand erosion underground, but there are still traces of weathering.

Or is this weird and dilapidated city, formerly above the surface? And when it's above the surface, it's been dilapidated for a long time?

As for the style of these broken walls, it is also something that Gao Longzang has never seen. There are some traces of ancient Western architecture, but they are not completely consistent, and even, even in the farthest distance as far as the eye can see, there are still some pavilions similar to those in ancient China. Of course, those things have also been dilapidated, only a few pedestals and broken pillars remain, and only a few of them have retained their top covers, but they are also full of holes.

What is this? A hodgepodge of style?

And in Gao Longzang's cognition, even the ancient West would not come up with such a style. This qiē is beyond his cognition.

And what surprised him the most was that in the very center of the area, there was an old circular building, which was basically in good condition. It is like the ancient Roman Colosseum, with a diameter of about 100 meters and a height of three floors, and it is not known what it is within the circular area.

The only preserved building is at the heart of this dilapidated city, both in terms of location and size.

Therefore, the source of the ideological power that is extremely valued by the Alien Martial Arts Society should also be here.

As for the top of the area, the top of the dozen stories above, it is completely modern - rows of electric lights. This was obviously done later by the Alien Martial Society, in order to facilitate activities in it. These lights should be bright day and night, because there is no light in the ground so deep in the first place. Gao Longzang's ability to see this qiē was also caused by these lights.

Perhaps, this is too important, and the precautions of the Ground Knight Palace are strict enough, so there are no guards or anything in this underground space. After all, even a master like the "Twelve Titan Gods" is only qualified to come in for ten days a year, and the "Creation God" only has a time quota of twenty days, so how can ordinary people enter and exit such an important place casually.

In this way, it is convenient for Gao Longzang. Although he was not sure if there was any surveillance equipment, he could no longer hide in the stone steps of the pit, because the footsteps of Kronos behind him were getting closer and closer.

As a result, Gao Longzang sprinted out suddenly, and could only use guò high-speed movement to try to keep his figure from being seen. After jumping out forty or fifty meters, he came under a huge fallen pillar. Gao Longzang hid his body in the gap under the giant pillar, and there was a broken wall in front of him to cover it, at least not from Kronos's attention.

And his current location is about three or four hundred meters away from the central rotunda.

At this time, Kronos had already walked out of the door, not noticing anything unusual in the slightest. In his head, he seemed to be thinking about the terrifying strength of the paladin, and it was also full of jealousy and anger. This kind of affection can easily make people lose their minds and relax their vigilance.

Kronos took a deep breath and strode along a cleared stone path to the circular building in the middle. Gao Longzang, who was not far away, was sure that the source of the so-called mental power must be there. Even the holy spear he had taken out of it just now should have been stored there.

Let Kronos go a long way forward, keeping a safe distance. While Gao Longzang was paying attention to him, he couldn't help but look at the broken wall in front of him. As a result, the broken picture above aroused his great interest and shock.

This broken wall was supposed to be a building with carved murals. What appeared in front of Gao Longzang's eyes now was only a broken corner of the entire mural.

However, this kind of carving painting is by no means the simple and crude line picture of the ancient period, and its complexity and fineness are no less than those master carvings in the European Renaissance.

However, the age of this mysterious region is far from comparable to the history of civilization known in Europe. In other words, the area should be in ...... Prehistoric. It was in that more ancient and profound era that there were traces of extremely brilliant civilization, and even the level of sculpture and painting had reached a very high level.

Moreover, the content of the broken painting in this corner seems to depict life at that time. There are strangely dressed humans on the ground, but the picture is small and weathered, and it is not real to see; In the upper part of the picture, which represents the sky, there is a carved airship.

There was even an airship...... What kind of world was it back then, it was too much of a hodgepodge, wasn't it?! Gao Longzang was speechless.
