Hu Xuanyun didn't ask directly, but the dean who led the way in front of him may also know that Hu Xuanyun didn't know about the existence of the back mountain, so he explained it slightly.

It turned out that Jingyue Academy, in the original time, was a big mountain, and later Jianyang City was located here and this area was divided into the academy area, so the mountain was flattened.

If the academy is located according to the original mountain, it is at the highest position at the foot of the mountain, and of course, the Mirror Moon Pavilion next to it is also Ruci.

As for the other academy gates in this area, they have long been only located at the foot of the mountain.

And the back hill of the sage's place just now is actually only the position behind the academy, and the back of the academy is exactly the back mountain of the previous mountain.

Of course, this is not the reason why the saint called the back mountain, the real reason is that when the Jianyang Kingdom was built here, the mountain was not directly wiped out by strong means, but by some kind of secret method, and the mountain was directly isolated into some kind of mirror space as Zheng

That is, the original mountain, in fact, still exists, but it does not exist in the world where Hu Xuanyun is currently located, but in a mirror space that has been opened up, and the location is still here in the academy.

Behind the Mirror Moon Academy, there is a passage to the mirror space.

Therefore, if you want to enter that mirrored space, you have to go to the back of the academy and enter through that special passage.

As for the reason why the mirror alien space and why the mountain had to be put in it, listening to the dean, that mountain is very extraordinary, and it can be regarded as a spiritual mountain in itself.

Lingshan, in fact, is similar to Lingtian, except that one is Lingtian, and the other is an entire Lingshan.

And it is precisely because of such a spiritual mountain that this is the main reason why Jianyang City was located here in the first place.

It can be regarded as the true foundation and heritage of the entire Jianyang Kingdom.

Another point is that in addition to the passage behind the Mirror Moon Academy, which can lead to the mirror space, there is also a passage, which is located in the palace.

In addition, that mirror space is also the place where the saints of Jianyang Country live, although there are not many saints in Jianyang Kingdom, there are only two or three, and one of them is old and about to enter the earth to talk.

But even if it is Ruci, that mirror space is still the best place in the entire Jianyang Kingdom, even the location environment of the palace is far inferior to the mirror space.

After listening to the dean's deliberate explanation, Hu Xuanyun also understood why the saint called them to the back mountain, and where the back mountain was.

Of course, after that, the dean also specially told Hu Xuanyun that for the matter of the mirror image of the different space and the Lingshan, don't spread the word, there are very few people in the entire Jianyang Kingdom who know about these two existences, except for the saints and the great Confucians, only a few members of the royal family know.

Even the gentlemen of the Mirror Moon Academy did not know about these two existences.

Hu Xuanyun also knew the importance of this matter, so he also took the initiative to swear with his Dao heart, promising not to publicize the matter of mirroring the other space and Lingshan.

Hu Xuanyun took the initiative to swear with her Dao heart, which made the Confucians very satisfied, and the dean was even more satisfied, after all, if possible, she was also unwilling to inform Hu Xuanyun of these two existences now.

But who let the sage speak before, the sage is all and wants Hu Xuanyun to go to the back mountain with him, then Hu Xuanyun will also know about the existence of the mirror space and the spirit mountain sooner or later, so the dean also explained to her directly.

Of course, after the dean finished explaining, he was also ready to ask Hu Xuanyun to make an oath, and make an oath that he could not publicize the two existences of Jianyang Kingdom.

It's not that I don't believe in Hu Xuanyun's character, of course, I really don't believe in it, but these Confucians present have also made oaths like this.

So just now, the dean was still thinking about how to export, so that Hu Xuanyun could swear to keep it secret and not be disgusted.

I didn't expect Hu Xuanyun to be so upright, so I swore directly, I was very clever, and naturally the dean was very satisfied.

After that, the group came to the periphery of the dense bamboo forest behind the academy, followed the dean into the bamboo forest, and after walking for a long time, they saw a bluestone staircase that gradually spread downward.

The dean walked directly to the top of the bluestone steps and went down, and the Confucians followed behind one by one, Hu Xuanyun was the last to follow, after all, who made the bluestone steps very narrow.

The bluestone steps are only enough for one person to pass, so naturally they can only pass one by one.

It didn't take long for Hu Xuanyun to follow the dean and the Confucians to the edge of a stone well, Hu Xuanyun thought that it was just the shape of a stone well, and there might be another mystery below.

Just when Hu Xuanyun was looking at the stone well and guessing, the dean opened his mouth, but he didn't let everyone jump directly into the stone well, because it was really the stone well, and there was well water in it, and it was useless to jump from the stone well.

What the dean said was deliberately explaining to Hu Xuanyun.

"Although the passage is under the stone well, it is not inside the stone well!" said the dean went to the edge of the stone well, groped for a certain stone there, and vigorously pressed it inside.

Immediately afterwards, Hu Xuanyun was keenly aware that in a piece of land not far from Shijing, he sank, and estimated that it was the passage.

It was the dean who took the lead, and several great Confucians did not hesitate, they followed directly behind the dean, and went down to the passage to be Zheng

And Hu Xuanyun only hesitated for a moment, and then went down, only to find that it was indeed a downward passage inside, and there were steps, but it was a little too dark, but for Hu Xuanyun, no matter how there was no light, as long as the divine sense was swept, he could clearly know the environment in the passage.

I followed behind, and kept going down the stairs, but slowly there was a fire, and when I got closer, I found that the two walls of the passage in this area were inserted with burning torches, and there were burning torches at intervals for lighting.

I don't know how far and deep I went, but slowly Hu Xuanyun found that he was not moving in the downward direction, but had begun to calm down.

After perceiving this, Hu Xuanyun estimated that he should be almost at the end of the passage, as for why he didn't just use his divine sense to sweep the entire passage?
