Qingyun Mountain, on the mountain behind Tongtian Peak, has two important places.

One of them is the ancestral hall of Qingyunmen.

As the name suggests, the ancestral hall of the patriarch is naturally the place where the ancestors of Qingyunmen are enshrined, from the Qingyunzi who founded the Qingyunmen to the patriarch of Qingye, and then to the ancestors of the past dynasties, they all have a spiritual position in the ancestral hall of the patriarch, and the incense is endless every day, and every important day, Qingyunmen will be under the leadership of the head of the house, and come here to worship the ancestors.

The second is the holy place of Qingyunmen - Phantom Moon Cave Mansion.

Thousands of years ago, the amazing and brilliant Qingye Patriarch came out of the retreat in the Phantom Moon Cave Mansion, and since then the Qingyun Gate has been the best in the world, and the leader is the leader.

Therefore, since the Qingye Patriarch, the Phantom Moon Cave Mansion has gradually become another sacred place of the Qingyun Gate, and only the head of the sect can enter this place for thousands of years.

And today, on the mountain behind Tongtian Peak, on the path leading to the Phantom Moon Cave Mansion, in addition to the head of Qingyunmen, Dao Xuan Zhenren, there is also one more Qin Zhou.

Obviously, for Qin Zhou's request to borrow the Zhuxian Ancient Sword, in the end, Dao Xuan Zhenren agreed.

Three days ago, after helping Qingyun defeat the Demon Sect disciples who came to attack, Qin Zhou proposed to Dao Xuan Zhenren and other leaders that he wanted to borrow the Zhuxian Ancient Sword.

At first, including Dao Xuan Zhenren, the heads of all the veins disagreed, one was because of the precepts of the ancestors of the past dynasties, and the other was because the Zhuxian Ancient Sword itself was a dangerous thing.

Although everyone didn't know what Qin Zhou's use of borrowing the ancient sword was, they didn't want him to ruin his good future because of the Zhuxian Ancient Sword, so everyone was surprisingly unanimous, and they didn't want him to contact the Zhuxian Ancient Sword.

Qin Zhou had no choice but to reveal that he had already learned two volumes of Heavenly Books, and expressed to everyone that he wanted to collect all five volumes of Heavenly Books and improve the idea of Taiji Xuanqing Dao.

When everyone heard this, they were all shocked, but then they also understood the reason why he entered the realm so quickly, but everyone was still puzzled, what is the relationship between the Book of Heaven and the Zhuxian Ancient Sword?

Qin Zhou knew that the Zhuxian Ancient Sword itself was the fifth volume of the Heavenly Book, but how could he explain to everyone how he knew?

After thinking about it for a while, Qin Zhou told everyone about the experience of going down the mountain for two months, and said that it was an ancient book engraved in the Heavenly Emperor's treasury on the giant tree of the Death Swamp.

When everyone heard this, they were shocked again, obviously they didn't expect that the Zhuxian Ancient Sword still had such a secret, but they also completely believed Qin Zhou's explanation, but everyone immediately began to get excited again.

The Tai Chi Xuanqing Dao comprehended from only one volume of the Book of Heaven has such power, if you collect all five volumes of the Book of Heaven and perfect the exercises, maybe you can really solve the mystery of immortality.

Everyone did not have the confidence to comprehend the Book of Heaven, but for Qin Zhou, who was qualified against the sky, they all had great hopes, if in their lifetime, they could have someone to understand the mystery of immortality, and they would die without regrets.

After that, for Qin Zhou's request to borrow the Zhuxian Ancient Sword, everyone, including Dao Xuan Zhenren, agreed.

But Dao Xuan Zhenren was attacked by the Cangsong Dao people that day and injured the origin, so although he was in a hurry, he also cultivated for three days, and Dao Xuan Zhen brought Qin Zhou to the Phantom Moon Cave Mansion where the Zhu Immortal Ancient Sword was enshrined.

......

Warm sunlight, pouring from the sky, was falling on the two on the forest path.

On both sides of the trail, there are dense forests, evergreen pines and cypresses, and dense vegetation, only this mountain path winds its way to an unknown and mysterious place.

In the depths of the woods, there is still a faint sound of crisp birdsong, there is a calm atmosphere everywhere, even in the air, there is also a cold smell, and the surroundings are quiet, only the footsteps of the two people "da-da" echo between the mountains and forests.

Compared to three days ago, Dao Xuan Zhenren's face was much better, and his speech was also neutral and powerful, obviously his injuries had recovered, but since entering this path leading to the Phantom Moon Cave Mansion, Dao Xuan Zhenren became serious again, so the two of them walked in silence all the way.

Qin Zhou changed into a purple regular dress today, and quietly followed behind Dao Xuan Zhenren, looking at the surrounding environment from time to time, but there were almost no mountains and forests and trees all the way, and there was nothing else special.

After walking for more than ten minutes, Dao Xuan Zhenren suddenly paused.

"Elder Qin, it's here!"

Hearing this, Qin Zhou stopped and looked forward, his eyes couldn't help but move.

I saw that on the gentle slope in front of me, there stood a cave that was half higher than ordinary people, about seven feet wide, surrounded by green vines and thorns, and even a few branches hung down from the hole, and the mountain wind blew, and the vines were also gently shaking.

And just under the green vines, the stone above the entrance of the cave is engraved with four characters - Phantom Moon Cave Mansion.

In addition to the meaning of these four words themselves, everything around here, even including these handwritings, seems so ordinary, the thousand-year-old root of Qingyunmen is actually hidden in such an ordinary cave?

Qin Zhou was a little surprised.

On the other hand, Dao Xuan Zhenren didn't seem to have much emotion, but the moment he walked in front of this cave, he sighed slightly.

"I haven't been here in years!"

Dao Xuan Zhenren sighed, and without waiting for Qin Zhou to speak, he walked straight towards the cave.

Qin Zhou glanced at it, didn't speak, followed without hesitation, and stepped into this ancient cave that had existed for thousands of years.

There is no imaginary deep and long, what appears in front of you is just a simple and unpretentious stone room, and you can see all the decorations in the cave at a glance.

A few stones were piled up in the corner of the wall, and there was a faint moss in the slightly moist place in the corner of the wall, the only difference from the outside of the cave was that it was very quiet here, and when I walked into the cave, it seemed that suddenly everything was quiet, as if it was cut off from the outside.

Retracting his gaze from the surroundings, Qin Zhou's gaze finally fell on the stone wall facing the entrance of the cave.

I saw that in the flat stone wall, there was a stone slab Taiji pattern, and there were many signs of damage on the map, which was obviously a thing that was very old, but this was the only thing in this cave that could have something to do with Qingyunmen.

Dao Xuan Zhenren paused slightly, then raised his feet and walked up, stopping in front of the Tai Chi pattern, and the next moment, he gently put his hand on the Tai Chi pattern, and a faint blue light emanated from between his palms, which was the breath that belonged to the Tai Chi Xuan Qing Dao.

The next moment.

As if a person who had been sleeping for a long time finally woke up, the peace in the stone room was suddenly broken by a distant soft sound, as if the whole cave sighed softly, something began to turn, and then, the Taiji diagram also lit up with cyan light, and at the same time, the pattern began to turn.

"Knock! knock! knock......"

Exactly a week after turning from left to right, there was a sudden "click" sound from the stone wall, and everything stopped.

At the same time, Dao Xuan Zhenren also withdrew his arm and waited quietly.

The silence disappeared in a moment, and a dull rumbling sound began to sound in the cave, and the next moment, on the right side of the Tai Chi pattern, a crack in the shape of a ring suddenly appeared in the originally complete stone wall, and then slowly rotated to the side to separate, revealing a secret hole.

It's just that at the entrance of the cave, there is a strange thing that looks like a gray mist, which looks like fog and water waves, spinning non-stop, and the inside is hazy and unclear, and it is not real at all.

"Let's go!"

Dao Xuan Zhenren was silent for a moment and took the lead in walking in.

Qin Zhou did not hesitate, and stepped into the gray water curtain without hesitation.
