Cheng Yu and the others naturally didn't know that they were already well-known and well-known in the cultivation realm. I don't know if Kunlun and Xuantian Sect have used new tricks against him again.

At this time, Cheng Yu and the others were still looking for Yang Mirror or some clues in the Holy City in the ruins of the Holy City, but the ruins of this Holy City were obviously much larger than they imagined.

They found the stone plaque of the Open Heaven Mirror before, that is, they found the main gate of the Open Heaven City, so they had a certain understanding of the layout and direction of the Open Heaven City, but they searched for several kilometers all the way, but they did not find the location of the City Lord's Mansion.

With no choice, Lan Ya once again sucked away the original loess for several kilometers around, but they found the other from one end, but they still didn't find the so-called City Lord's Mansion, which surprised everyone.

"Senior Brother Yu, this is a little wrong, it has been more than ten kilometers since we found the stone plaque of Open Heaven City, but there is no shadow of the City Lord's Mansion, has it not reached the center of this city from such a long distance?" Xinluo stood in place, judging from the direction, the location of the stone plaque is the north gate of the city, and they are now looking for it to the south, but this is obviously not the location of the south gate, and there is still an unknown distance to the south.

As a result, Lanya continued to suck away the loess several kilometers in the south, so that it was almost a dozen kilometers away from south to north. As they continued to search south, they found that the ruins had disappeared after walking a few kilometers.

"No, how can there be?" everyone saw that further south, it was a flat land, indicating that the city was only so wide.

"It seems that this place is where the South Gate is located, but we actually went from the North Gate to the South Gate, but we didn't find the City Lord's Mansion, could it be that we missed it?"

"Maybe this City Lord's Mansion isn't in the center of the city, maybe it's somewhere else!" Xinhe said.

"That's going to be troublesome, do we really have to rummage through the entire city?" Xinluo said depressedly.

Because they didn't want to miss any hope, they searched very carefully, and as a result, they searched for more than half a month from north to south.

If you look along the center of the city, you will definitely find the castle lord's mansion, and in that case, you may know some news of the sunshine. But no one knew that this city lord's mansion was not in the center of the city at all, and now this situation could only be searched by the whole city.

"Judging from the distance between north and south, the distance between the east and west of this city is more than ten kilometers, Brother and Sister Lan Ya, I'm afraid I will have to work hard for you again. Xinhe said.

"Anyway, it's already like this, Brother and Sister Lanya, you just clean up all the ruins of the entire city. I don't believe it, I can't find the location of the City Lord's Mansion in the entire city!" Xinluo said.

"Let's come on the side, if you find it here, then there is no need to spend that energy!" Cheng Yu thought for a while and said.

"Alright!" Lanya nodded, heading towards the ruins to the east again.

Half an hour later, the ruins on the east side had been cleared, and everyone continued to look for the east side.

But after three days, the entire eastern area was also searched, but everyone still found nothing.

"It seems that there is no drama here, and most of this city lord's mansion has appeared in the west!" Xinhai said disappointedly.

"Let's talk about it when we're done, anyway, the city is only so big, we will find it after all. Although Cheng Yu was also extremely disappointed and depressed in his heart, he also fought hard in order to be able to find something useful.

Now that everyone has come here and spent so much time, it is natural that we can't give up halfway.

Everyone felt devastated, but there was really no better way to find clues, so they could only continue to search.

In such a boring search, Xinluo casually picked up a large stone slab, and before he could see if there was anything useful underneath, he suddenly roared, and saw that all the concaves in front of him were concave, and all of them collapsed at once, which startled Xinluo.

"Look! There is a hole here!" Hearing this loud noise, everyone rushed over, and suddenly saw a hole in front of Xinluo.

"Haha! I found out that I am really a lucky star, it seems that I found all the discoveries!" Xinluo reacted after being stunned, and immediately laughed.

"Quick! let's go down and have a look, maybe there's something we're looking for!" Everyone was in no mood to pay attention to Xinluo at this time, after looking here for so long, they finally found such a hole, and everyone was obviously attracted by this hole.

"Hey, I found this hole, aren't you going to praise me for turning it over?" Xinluo saw that everyone had entered the cave, but he was left alone at the back, and immediately chased after him and shouted.

Everyone walked down the stairs all the way to the entrance of the cave, only to see two stone doors hidden, and looked into the gap, and it was pitch black.

"Shall we go in?" asked Kokomi expectantly.

He finally found something interesting, and he was so excited that he wanted to go in and see what was inside!

"Aren't we here just to find the secret of the Yang Mirror, there may be something we are looking for, of course we have to go in!" Xinluo said.

"That's true, but it seems to be a little eerie in here, and it doesn't seem like a good place, I'm afraid there will be danger?"

"It shouldn't be fine, look at this door is hidden, there shouldn't be any terrible existence in it, otherwise it would have run out a long time ago!" Xinluo said disapprovingly.

"No matter what, it's better for everyone to be careful, I'll lead the way in front, everyone be careful to follow!" Cheng Yu took out a luminous stone, slowly pushed the stone away, and entered.

Everyone also took out the luminous stone one after another, illuminating the entire cave, and what appeared in front of them was a not long road, about twenty or thirty zhang long.

In addition to the thick cobwebs on the wall of the corridor, there is also a row of lampholders, but the power stones on it are gone, so there is no light.

In addition, there are no other decorations or embellishments on the walls of this corridor, not even a fresco.

When the people had walked through the twenty or thirty zhang road, two more stone doors appeared in front of them, but one stone was still closed, and the other was open.

"Senior Brother Yu, be careful of deception!" Xinhe reminded in the back.

Cheng Yu nodded and first used the luminous stone to shine inside the door, and found that it was empty and there was no danger, so he went in first, and the others carefully used the luminous stone to shine and followed in.

It's a stone room!
