This stone door is located behind the incense case and is extremely secretive. Because the incense table enshrines the spiritual positions of the masters of the Xuanmiao Nunnery in the past dynasties, few people dare to look at them directly.

Even if the owner of the Xuanmiaoan came to clean the spiritual seat, then out of respect for their ancestors, they would never move the spiritual seat. And Ling Yu was not a disciple of Xuanmiao'an, so he had less heartfelt awe for the spiritual position, so he accidentally opened the passage behind the spiritual position.

And on the wall behind the spiritual seat, a landscape map is depicted. In the picture, Cangshan stands proudly, with thousands of blue waves, lifelike, and Ling Yu's charm makes Ling Yu admire.

It is conceivable that anyone who comes to this place, even if they are attracted by the landscape map, will never think that the purpose of this landscape map is not for people to see, but to cover up the mysterious passage behind it.

Yan Suyi's master may have known about the existence of the passage back then, but since Yan Suyi took over as the head of the nunnery, she also knew that Yan Suyi was definitely not Liu Furong's opponent, so she deliberately concealed it. And about this passage, Yan Suyi should not know, otherwise she would not have forgotten to explain the passage to herself when she was dying.

"Since this passage is so secretive, it is obviously not an ordinary place. Moreover, Yan Suyi did not tell herself, which means that she did not know about this matter. Ling Yu stroked his earlobe and guessed.

Liu Furong has ill intentions, the city is very deep, and the methods are very vicious. Presumably, when Yan Suyi's master accepted her again, she also expected that Xuan Miao'an would have this catastrophe in the future, so she didn't tell Liu Furong about the passage.

And judging from Liu Furong's character, she is full of hatred for Xuan Miaoan, and it is impossible for her to take the initiative to clean the spiritual position. That way, it would be impossible for her to discover the existence of the passage.

So, what is the place behind this secret passage? The spiritual position here has not been cleaned for hundreds of years, which means that the passage behind it has also been sealed in the dust for hundreds of years. What secrets are buried in such a mysterious passage?

Ling Yu pondered as he walked towards the stone gate. At this time, he finally understood why the main hall of the Elder Pavilion was built on such a strange mountainside, as if embedded in the green mountains. Because only in this way can the ancient cave be well hidden.

The first feeling when I first entered the stone gate was the vicissitudes of life, and the air was filled with the smell of decay, a dead silence that had not been breathed for a long time. There was an indescribable loneliness in the air, as if it were a fierce Jedi that no one could enter.

When Ling Yu stepped into the passage behind the stone gate with one foot, he lost his mind for a moment. Then, with a slight shake of his head, he decided that he still wanted to go deeper into the passage.

Ling Yu actually only had sympathy for Xuan Miao'an, but did not have a sense of closeness like Tianjimen. After all, this is not his master's sect, just a cave that has been entrusted.

Of course, for the sake of Duanmu Yuhan and Yan Suyi, even if Ling Yu didn't have too deep feelings for this place, he still wouldn't let the disciples of Xuanmiao'an suffer from disasters and ignore them. Since Yan Suyi entrusted everything to him, he had to do his best, worthy of Yan Suyi under Jiuquan.

As for whether to go to the passage, Ling Yu did struggle for a while, Ling Yu knew his identity very well, and it was indeed rude to venture into this mysterious passage. But if he turned away, he was indeed very unwilling.

In the end, curiosity triumphed over reason. Ling Yu took a deep breath and stepped into the passage. And just after he entered the passage, the stone door at the entrance of the passage was closed. The stone door closed so quickly that he didn't have time to react.

When the stone door closed, the passage seemed to fall into darkness in an instant, and the five fingers could not be seen. The sudden change made Ling Yu frown slightly, and he unconsciously sacrificed the broken sword, and at the same time exuded his divine sense, sensing the changes around him.

This is a habit that Ling Yu has cultivated for decades of traveling through the red dust, but whenever he encounters a scene where he cannot predict the good and the bad, Ling Yu's first reaction is to sacrifice the broken sword and wait for it.

However, it was all a false alarm. Although the environment in the cave was darkened by the closure of the stone door, fortunately, there was no danger coming. And the stone door that was closed was just to avoid others from noticing.

Ling Yu exuded his divine sense to investigate carefully, and found that there were no other creatures in the cave. Only then did Ling Yu put his mind at ease, wanting to use his divine sense to "see" the surrounding environment clearly.

But before Ling Yu could take a closer look, a sound like a candle flame being blown by a breeze suddenly came from both sides in front of him. Then, two bright lights suddenly lit up, revealing the scene in the cave to his eyes.

The passage is circular in shape, about eight feet in diameter. The two sides of the passage are arc-shaped, and there are very obvious traces of artificial excavation. The traces of the knife and axe on it are very conspicuous, as if telling the past to future generations.

The height of the passage was quite suitable for Ling Yu, although it was not suitable for fighting, but it could not touch his head.

The cave was very dry, and the smell of corruption was pervasive, making it impossible to calm down.

The further you go inside, the higher the temperature. When Ling Yu walked hundreds of steps, he felt more and more irritable. He knew that it wasn't the strange prohibitions in the passage, but the lack of popularity and the unusually stuffy heat.

As Ling Yu headed deeper into the passage, the ancient lights on both sides lit up as well, as if they were deliberately illuminating the way forward for Ling Yu.

These ancient lamps are made of unknown material, emitting a soft yellow glow, very similar to the light of a candle flame. The most important thing was that Ling Yu didn't even know how they were ignited. The candle flame keeps bright, making the passage more and more mysterious.

When Ling Yu walked to Baizhang, he found that the cave was gradually becoming wider.

The candles on both sides swayed from side to side with the breeze swept by Ling Yu's swift movement, but they were not extinguished. It is as tenacious as a spring grass, undefeated through wind and rain.

When Ling Yu had been walking for about half an hour, he suddenly heard the sound of water flowing in front of him. The sound of the water was like a bent spring flowing down from the sky and falling into a small pool. The crisp sound was very pleasant, cleansing Ling Yu's heart.

After hearing the crisp sound of the clear spring, Ling Yu's spirit was shocked, and he knew that he should be almost at the end. Thinking of this, Ling Yu became more and more excited, and hurried forward along the passage.

After another cup of tea, Ling Yu finally came to the source of the clear spring. It was indeed the end of the passage, and the cool air made Ling Yu extremely comfortable.

At the end of the passage is an empty cave. It is about 10 zhang high and 30 zhang square. When Ling Yu yelled excitedly, the voice echoed in the hole, as if another Ling Yu was responding to him.

The top of the cave is less like a man-made one, but more like a naturally formed roof. Because on the top of the cave, there are no traces of swords and axes. The stone walls there are smooth, as if they have been washed away by the current of water for thousands of years, washing away all the edges and corners.

At the top of the cave hung seventeen huge stones the size of a barrel. Those stones emitted a white glow, and although they were not night pearls, they looked like they should be some kind of strange stones in China that could glow on their own.

Because of the light of the seventeen boulders, the cave was as bright as day, and everything was distinct.

In the center of the boulder, a stream of water the size of a bucket's mouth poured down and fell into a small pool in the center of the cave.

The small pond was in the shape of a gossip, and the water falling from the dome was pouring right in the very center of the pool, and the splash of water splashed in all directions, making a crisp sound.

Next to the small pond, there are many flowers and plants. The flowers and plants are beautiful, and although they are not exposed to the sun, they are also very delicate. And Ling Yu could see at a glance that those flowers and plants were not ordinary plants, but 100,000 or even millions of years of spiritual herb treasures.

The rich aroma of these spirit grasses seemed to have turned into a thick mist, shrouding the roots and leaves of the flowers and plants, nourishing the spirit grass that had not yet died.

There are no signs of artificial excavation of the walls around the cave, or perhaps they were once reclaimed and then carefully repaired.

On the surrounding walls, eight huge stone carvings are depicted. The characters on the stone carvings are lifelike, and the mountains, rivers, plants, and trees are beautiful, like living creatures. Come to think of it, the person who carved the stone wall back then must have been a Danqing skillful hand, so that the stone carving could be so expressive.

Ling Yu first exuded his divine sense and sensed it around, and when he was sure that there was indeed no prohibition here, he took a step forward and looked towards the first stone carving on the right.

The scene depicted in the first stone carving is complicated because there are many creatures on it, they have human races, ghost races, demon races, and even ...... And the demons.

Moreover, the mountains and rivers depicted on the first stone carving made Ling Yu feel somewhat familiar, but he couldn't remember where it was for a while.

Ling Yu's eyes were slightly closed, and he carefully lived the scenes he had seen in his mind, hoping to find a place corresponding to the stone carving.

After about a quarter of an hour, Ling Yu suddenly opened his eyes. He looked at the first stone carving again, a look of shock in his eyes. Because he had already guessed that the place depicted in the first stone carving was the Xuanmiaoan in this world.

Because the age of this stone carving is very old, and under the changes of time, today's Xuanmiaoan is very different from before. Therefore, Ling Yu felt familiar when he saw the stone carving, but he couldn't remember where he had seen it.

The creatures carved in the stone gathered around a huge heavenly gate, and they looked at each other as if they were discussing something.

And when Ling Yu's eyes looked at one of the Terran women, his eyes were full of incredulity. He had already guessed the identity of the Celebrity woman, because not long ago, he had seen this woman in the main hall of the Xuanmiaoan. Or to be more precise, he had seen the statue of the woman.

Because this woman is the founding ancestor of Xuanmiaoan, the Emperor Zilin!

Thinking of this, Ling Yu finally understood the period depicted in the first stone carving. Those days actually happened in the beginning of the Xuanmiaoan Endless Years ago!
