Cheng Yu was also carefully considering this question at this time, what do these three paintings represent? Are they just three places?

But why is it so coincidental that the meaning expressed by these three paintings happens to be the five elements of yin and yang, and this is exactly the meaning of the seven fairy mirrors of the Open Heaven Mirror.

If the elements represented in these three paintings are really the seven fairy mirrors, then these three places represent the seven fairy mirrors.

However, these three paintings were already in existence long before the destruction of Kaitian City. Naturally, it is impossible for them to know what will happen in the future, so in other words, the meaning of these three paintings is not to tell them to go to these three places to find the Open Heaven Mirror, but to have another meaning.

But what does this mean otherwise?

"These three paintings are not as simple as we imagined, you think about it, these three paintings were not painted after the destruction of this Open Heaven City, at that time the Open Heaven Mirror was still in this Open Heaven City, how could they draw three paintings to tell us where to find the Seven Immortal Mirrors in the future? Could it be that they would not know the prophet?" Cheng Yu said.

"That's right, these three paintings have already been painted when the Open Heaven Mirror is still here, in this case, how can these three paintings represent the location of the Seven Immortal Mirror?" everyone nodded, feeling that Cheng Yu had pointed out the point at once.

"If that's the case, then these three paintings must have other meanings, but how do we know what the other meanings are?"

"This is really a difficult point, we don't care what this third painting refers to, but we have to first understand what the meaning of these three paintings is?" Cheng Yu said.

"Why don't we just expand these three paintings first? Since we can't find the place described on this painting now, let's save it first, and when we return to the cultivation realm, we can buy a map of the cultivation realm and compare it?" Xinluo said.

"Well, this can be available, so you wait first, I'll rub these three paintings first. Cheng Yu nodded, thinking that this method was good.

Although the specific location of the first two paintings has been found, in order to preserve the complete information here, it should be rubbed together.

However, this mural is quite large, but they don't have such a large canvas. When there was no way, Cheng Yu directly took out a few white robes from his storage bag and rubbed the three murals respectively.

"Senior Brother Yu, then should we stay now to figure out the true meaning of these three paintings, or do we directly return to the cultivation realm with this rubbing map?" Seeing Cheng Yu put away the three rubbings of the map, he asked.

"Let's see if there are other secret doors in this stone chamber first, maybe we can find some other information!" Cheng Yu looked at the wide stone chamber and said.

In the past, when he was in the Five Great Shrines, he had encountered several such stone chambers, but those stone chambers had secret doors inside, so he finally found those treasures.

Although this Open Heaven City can't be compared to the Divine Palace, maybe those of his people have such a habit, and they will also set up a secret door in such a stone chamber to store more important things.

So a dozen people began to pat and knock here and there to see if there were any other secret doors in there. However, to everyone's disappointment, it seems that there really is only such a stone room here, and it is not as complicated as they imagined.

"It seems that this is just an ordinary stone room, and there is no secret door!" Xinluo said, shaking his head.

"Well, did you find anything else?" asked Cheng Yu.

"No, it should be almost, even these murals have been seen, and no new information has been found!" Xinhe shook his head.

"In that case, then let's go out!" Cheng Yu nodded.

There were no new discoveries, and everyone had to go back to the surface together. Although I didn't find any important information in this stone room, I was able to find three unusual paintings, which was not in vain, and I still gained something after all.

Moreover, they also felt that these three paintings were not as simple as they seemed on the surface, and even if they did not refer to the place where the Seven Immortal Mirrors were located, they must have other important meanings.

Back on the ground, everyone was greeted by a huge ruin.

"Senior Brother Yu, do we still want to look for the City Lord's Mansion?" Xinhai looked at the vast ruins and suddenly had a headache.

In order to find the City Lord's Mansion, they had already turned over half of the ruins of Kaitian City, but they only found such a stone room, and Xinhai felt so tired.

So when I saw that almost half of the ruined city had not been searched, I suddenly felt uncomfortable again.

"Are you sure that the place where we are now is not the City Lord's Mansion?" asked Cheng Yu.

"Ah, Senior Brother Yu, do you mean that the stone chamber below here is the stone chamber of the City Lord's Mansion?" Xinluo exclaimed.

"I can't be sure, it's just that I think in the entire Open Heaven City, the place where the news of the Open Heaven Mirror can be drawn so clearly, except for the City Lord's Mansion, I'm afraid there is no other place!" Cheng Yu said.

The area is full of ruins, and tens of thousands of years have passed, and many things have been weathered, so it is already difficult to make out certain things.

At least judging from what they saw now, they couldn't tell if this was the City Lord's Mansion at all.

"Senior Brother Yu, then you say, could this legendary Mirror Immortal be the city lord of this Heavenly City?" Xinhai asked curiously.

"It's hard to say this, since this city is called Open Heaven City, it means that this Open Heaven Mirror is very important to this city. And it seems that the common people also know about the Open Heaven Mirror, so it seems that the immortal in this mirror may indeed be the city lord of this Open Heaven City.

If the Immortal in the Mirror is not the city lord, but the Heaven Opening Mirror is in her hand, wouldn't that city lord be very embarrassed? The city she manages is named after the magic weapon in someone else's hand!" Cheng Yu thought for a while and said.

"Also, in this way, with such a large stone room to record everything in the Open Heaven City, only the city lord would do such a thing, I can't say that this is really the location of the city lord's mansion!

"Regardless of whether this is the City Lord's Mansion or not, I think the things we wanted were found in the stone chamber just now. Even if you turn the whole city upside down, I'm afraid you won't be able to find anything more valuable. Cheng Yu said.

The Open Heaven City was the city that existed when the Open Heaven Mirror had not yet separated, and the Yang Mirror they were looking for was after the destruction of the city. If they continue to look for it, they will not be able to record the future, so even if they find something about the Open Heaven Mirror, it will not be of much use.
