Although it was only a ruined city that appeared in front of everyone, from the location of these ruins, it can be seen that the layout of the entire ruins is very grand.

At a glance, it is clear that this urban area with a radius of several kilometers is only a corner of the city in those days.

"This side should be the main street, look at this wide street, although it has been dilapidated, but you can still imagine the houses here back then, the street is full of people, it's a pity!" Xinhe shook his head and sighed.

"The most pitiful thing is the people when this city was destroyed by outsiders, I don't know how many innocent bones were buried in these ruins!" Everyone flew all the way, looking for the location of the main city, and sighed with emotion.

"Invaders like these are supposed to be cut with a thousand cuts, so that they will never be reincarnated. It's a pity that the nightmare beast didn't tell Senior Brother Yu the identity of the enemy, otherwise, we would always have a chance to seek revenge on them. But now I don't even know who the enemy is, and it's infuriating to see the crimes left behind by these guys!" Kokomi said.

"Will find it! Since the Nightmare Beast said that when I had enough strength, it would know all this, and I believe it didn't lie to me. I won't let this day wait too long, how they committed the crime back then, I will return it to them ten million times in the future, so that they can't live or die!" Cheng Yu said coldly.

Tens of thousands of years ago, it must have been a place full of vitality, and the people lived and worked in peace and contentment, and lived happily. But everything that is good has been ruined by these greedy people, who have destroyed not only a city, but thousands of innocent lives.

Everyone naturally knew that Cheng Yu was not very comfortable seeing this scene, and everyone fell silent all of a sudden. After all, this is where Cheng Yu's clansmen live, but now that it has become like this, no one will feel good.

"Shall we go down and have a look?" Xinhe suggested.

"Aren't we going to look for the City Lord's Mansion? The City Lord's Mansion isn't down there, what are we going down to do?" said Xinhai puzzled

"Maybe we'll be able to find some useful clues in the ruins. Xinhe said.

After all, it was only their guess to find the secret of the Open Heaven Mirror from the City Lord's Mansion, maybe this secret was not in the City Lord's Mansion, but somewhere else.

Therefore, they only focused all their hopes on the City Lord's Mansion, and it was obviously possible to miss a lot of clues.

"Senior Brother is right, we can't just focus our hopes on the City Lord's Mansion. Uncle Taixuan only accidentally discovered this city of ruins back then, and with their strength at that time, they might not be able to clean up the ruins on a large scale like ours.

Unless he is extremely lucky and comes across the City Lord's Mansion, otherwise it will definitely be more difficult for him to find the City Lord's Mansion than us. Therefore, the secrets of the Open Heaven Mirror that he saw may not be the City Lord's Mansion, or some other architectural relics. Cheng Yu said.

"In that case, then we may not necessarily have to find the City Lord's Mansion. Xinluo nodded and said.

"That's natural, our purpose is mainly to find out some information about the past of this city and the situation of the Open Heaven Mirror, as long as we find these, naturally there is no need to stare at the City Lord's Mansion!" Cheng Yu said.

"If that's the case, then we'd better look for it separately, so it will be faster!" Yang Ruoxue said.

"Well, it makes sense, then let's all look for it separately, everyone be careful, it's best not to miss something you have doubts!" Cheng Yu nodded.

So, everyone dispersed, after all, they had cleared all the areas within a radius of several kilometers, and they were obviously a little less than a little bit of a ruin in such a large ruined place. If you look for them separately, although there are still a few people, at least it is much faster than getting together to find them.

However, now that the location of the ruins has been found, everyone is not so eager. The main thing is to find something useful, and not to go through it all over again.

Cheng Yu walked in this ruin, with a heavy heart, and turned over some stones in the ruins, and even found some human bones. Cheng Yu knew that the owner of these bones was likely to be a monk.

Otherwise, tens of thousands of years, even if they have not been weathered and corroded into dust, they may have become fossils. However, it cannot be ruled out that these bones were people who came to the ruins and died.

Cheng Yu was not interested in delving into this problem, and kept rummaging through the ruins, looking for piles of ruins, but he never found what he was looking for.

Obviously, although the city of ruins has been discovered, it is not easy to find something useful. Because it has been so long, this place is more dilapidated than expected, many things have been weathered, maybe what they are looking for is long gone.

However, Cheng Yu and the others did not give up, it took him three days to find less than half of the area in such a large area.

"Oh my God, the ruins we're seeing now aren't all there is to the city. We've been here for three days, but it's less than half of what we are now. If we don't find it here, we will have to continue to expand the area of the city, and I don't know how long it will take to find the news of the Open Heaven Mirror. Xinhai said helplessly.

"There's no way around it, a lot of things are buried in the rubble, and if we don't look like this, it's hard to find anything useful, and it's impossible to put what we want right in front of our eyes. Xinhe said.

"Found it!haha!Who said it was impossible, this thing is in front of me!" However, as soon as Xinhe's words fell, Xinluo, who was not far away, laughed loudly.

"No, this guy's luck is so good, he let him discover the ruins before, and now he has found the secret of the Open Heaven Mirror, it's too coincidental, right?"

However, as soon as Xinluo shouted, everyone ran to Xinluo.

"What did you find?" the crowd asked excitedly.

"That's it!Look, open the Heavenly City!" Xinluo said happily, pointing to the words on a large stone.

Everyone knows these three words, because these three words are not the strange symbolic words from before, but the words of the world they know.

Judging from the appearance of this large stone, it should have been set in the city gate. They looked around, the place was exactly on the border of remembering, and there were quite a few remnants of thick walls around it.

"That's what you've discovered?" Open Heaven City, what's the use of just these three words?" the crowd said in disappointment.

Originally, I thought that Xinluo had discovered the secret of the Open Heaven Mirror, but I didn't expect that it was just a broken stone plaque of the city tower, which was really disappointing!
