It turns out, they were the main characters.

The letter was written by the Queen of the Demon Realm, and its contents are related to the seal in the Pilgrimage Hall.

"I've been in the sect for quite some time now, so I've naturally explored the grotto-heavens within the Pilgrimage Hall before," Ying Guhuan said with a calm smile.

“However, I’ve never gone into that area,” she continued.

In the past, there had been several tremors, large and small, in the Pilgrimage Temple. Ying Guhuan had planned to enter the Pilgrimage Temple's cave to find out what was going on, but as soon as he stepped inside, he sensed an extremely dangerous aura and therefore did not go any further.

The letter from the Demon Queen mainly concerned the first Demon Emperor. She wrote about his life and concluded with four large characters: "Wait and see."

"What is the relationship between the Demon Queen and the First Demon Emperor? Does Sister Ying know anything about it?" Mu Zhi'an asked.

"The demon realm is currently divided into two factions."

Ying Guhuan said, "One faction consists of the remnants of demon cultivators led by the first Demon Emperor, and the other faction is the current Demon Empress." Ying Guhuan added, "However, over the past thousand years, the remnants of the first Demon Emperor have been basically wiped out and can no longer cause any trouble."

"If that's the case, why did the Empress tell me to wait and see?" Mu Zhian asked with some doubt.

If they could take this opportunity to eliminate the first Demon Emperor, that would be what the Demon Queen would most like to see.

Ying Gu Huan smiled and narrowed his eyes: "It's for your own good that you're telling me to observe the situation. The first generation of the Demon Emperor can't extend his hand within the Liangyi Sect, but he will still leave a shadow where the light can't reach."

"Does Sister Ying mean that there might be subordinates of the first Demon Emperor within the sect?" Mu Zhian understood Ying Guhuan's words.

If that's the case, then we definitely need to be careful.

Previously, Mu Zhian believed that the first Demon Emperor, who was sealed by the Azure Emperor, had no choice but to trust him.

But if someone within the sect is secretly contacting the First Demon Emperor, what would they do to rescue him?

We have to be careful... Mu Zhian nodded solemnly: "Thank you for reminding me, sister."

Ying Gu smiled and said, "When expressing gratitude, a simple 'thank you' seems a bit too inadequate."

As she finished speaking, her charming eyes gazed at Mu Zhi'an, and she said with a sweet smile, "Next time, remember to express your gratitude in a more practical way."

Mu Zhi'an understood immediately and nodded, saying, "This disciple understands."

Ying Guhuan did not make things difficult for Mu Zhian, but waved for him to leave.

Although she had quite a bit of ideas about the "natural furnace," the Azure Emperor was still inside Mu Zhi'an's body at the moment. If they started dual cultivation... it wouldn't be fun if the Azure Emperor found out.

After all, the reason why the Azure Emperor stayed in Mu Zhian's body was probably largely because he was a natural furnace.

The best time to strike will be after the Azure Emperor has reconstructed his physical body...

Ying Guhuan still has that much patience.

She's been stuck at the seventh level of the Void Returning stage for years, so enduring another month or two won't be a problem.

……

Tianhe Garden.

Bai Ruoxi wore a plain white dress with pale purple snow lotus embellishments. Her full breasts proudly pushed up the front of the dress, presenting a sight that would amaze anyone who saw it.

She slowly opened her eyes. Not far in front of her, a milky-white sphere shimmering with a gentle halo slowly rotated, transforming the surrounding mixed spiritual energy into purer spiritual energy for her to meditate and cultivate.

It must be said that the spiritual energy of the Liangyi Sect is much richer and purer than that at the foot of the mountain, so the purification speed is also faster, which naturally helps Bai Ruoxi's cultivation.

She gently raised her hand, and the energy of Heaven fell into her palm, then quietly disappeared from the room.

Bai Ruoxi sat up, her bare feet wrapped in a pair of white socks, with a delicate and beautiful black ribbon hanging from her ankles, making her already snow-white skin appear translucent and beautiful.

She stepped out of the room in her embroidered shoes, stretching languidly and revealing her slender and alluring figure.

Not far outside, there was a pond, reflecting the hazy moonlight. Several snow lotuses swayed in the night breeze.

Bai Ruoxi looked up and saw a maid in a yellow dress gazing at the moonlight under a pavilion not far from the pond, seemingly lost in thought.

Wei Mengrou noticed the gaze behind her and turned her head slightly to look over. She saw Bai Ruoxi walking towards her with her hands clasped together in front of her palace dress.

"Sister Mengrou, aren't you going to rest so late?" Bai Ruoxi asked with a smile.

“You don’t need to rest after reaching the Refining Spirit Realm,” Wei Mengrou said calmly.

Bai Ruoxi nodded slightly, not dwelling on the topic, and casually asked, "By the way, where is Young Master Mu?"

"It seems I was just summoned to Canghai Peak by a disciple sent by the Chief." As Wei Mengrou said this, she inadvertently glanced at the stunningly beautiful woman beside her.

Although Bai Ruoxi usually appears gentle and pitiful, she knows that this number one beauty of Tianxuan City is actually a very strong person. In front of Ye Lingxuan and even Lan Mulian, Bai Ruoxi always called Mu Zhian "Mu Lang".

As for why she is called "Young Master Mu" here, it is probably because Bai Ruoxi does not consider her an "enemy," or perhaps Bai Ruoxi does not take her seriously.

Whatever the reason, Wei Mengrou didn't care.

"Why are these chiefs taking such good care of him?" Bai Ruoxi asked softly, her delicate brows furrowing slightly.

In the past few months, the chiefs of the nine main peaks have sent some pills to each other, and the ones who sent the most were probably Canghai Peak, Tianji Peak and Dao Peak.

Let's set aside the library for now. After all, it's quite normal for Yan Ruyu to go to great lengths to give Mu Zhian, her only inner disciple, elixirs.

But it's rather strange that the other chiefs are also so enthusiastic.

"Perhaps it's because of the spirit dragon," Wei Mengrou said.

"Perhaps it's about the natural furnace or cauldron?" Bai Ruoxi said quietly.

Wei Mengrou looked up in surprise at the seemingly harmless and delicate beauty, seemingly not expecting that Bai Ruoxi, who meditated in Tianhe Garden every day, would know so much.

"What are your plans?" Wei Mengrou asked.

“The sect leaders are all renowned figures within the sect. If it were for the sake of the Natural Furnace, they would not openly express their desire to obtain it.”

Bai Ruoxi paused briefly before continuing, "Moreover, isn't Senior Qingdi also nurturing his spiritual consciousness within the Natural Furnace? In the short term, none of the chief disciples will be doing anything."

"If the Azure Emperor were to reshape his physical body in the future and leave his innate furnace, what would happen then?" Wei Mengrou asked, her usually aloof demeanor suddenly showing a hint of interest.

The allure of gossiping is irresistible, even to the maids.

"It is unreasonable for the head disciple to attack his disciple." Bai Ruoxi's gaze suddenly sharpened, and in the darkness, her demeanor became much more imposing.

However, less than a second later, she transformed back into the delicate and frail young lady of the Bai family, saying with deep concern, "The heads of these families are all at the Void Returning Realm. If their goal is truly to create a natural furnace, what am I going to do alone...?"

Being alone and weak, and merely a frail woman at the peak of the fourth level of the Divine Refinement Realm, Miss Bai couldn't help but feel somewhat worried.

Wei Mengrou took a sip of tea without making a sound.

"Perhaps I should go and have a heart-to-heart talk with Lingxuan," Bai Ruoxi muttered to herself again.

Although Ye Lingxuan also harbored some ill intentions towards Mu Zhian, the young girl was rather naive. This beautiful woman thought that rather than letting outsiders get involved, it would be better to reach a consensus with her two younger sisters first.

At least they are small fry and not much of a threat.

But if you accidentally bring in a great white shark, that's a different story.

"Tap tap..."

Bai Ruoxi lowered her eyes to look at the teacup on the table, her slender fingers gently tapping the table, her cool face showing a serious expression of thought.

Wei Mengrou's lips curled slightly, and she felt inexplicably pleased.

She found meditating and cultivating on ordinary days too boring, so being able to watch the gossip on the sidelines brought her inexplicable joy.

Just then, as if she had suddenly sensed something, she turned her head to look in a certain direction, her eyes flickering slightly.

Has someone else achieved the state of spiritual refinement and returned to emptiness?

Refining the spirit and returning to emptiness is the mark of a true immortal. Those who have reached the realm of returning to emptiness are powerful figures no matter where they are in the Nine Provinces.

There are very, very few people who can refine their spirit and return to emptiness.

Lan Mulian had only recently completed the Refinement of Spirit and Return to Emptiness stage, yet another person had already stepped into the realm of a terrestrial immortal.

Moreover, this direction leads to... Tianxuan City.

"Sister Mengrou, what are you looking at?"

Just as Wei Mengrou was having these thoughts, a young man's voice suddenly came from beside her.

Bai Ruoxi and Wei Mengrou looked up at the same time and saw Mu Zhian, who had just returned to Tianhe Garden.

“Someone in Tianxuan City has entered the Void Returning Realm,” Wei Mengrou said.

"Return to the Void Realm...?" Mu Zhian repeated in a low voice, his eyes filled with a hint of solemnity.

Nowadays, all the geniuses in Tianxuan City are cultivating in the Liangyi Sect. Even if there are geniuses in the city, they are only at the Qi Refining stage.

In other words, the person who has advanced to the Void Returning Realm this time must be an old monster or patriarch of a family in Tianxuan City.

If it's the Mu family, that's fine, but if it's another family... it could directly change the entire situation in Tianxuan City.

It seems I'll have to find some time to go back and visit in the next few days... Mu Zhian looked thoughtful.

"Mu Lang, why are you back so late tonight? Did one of the chiefs come looking for you?" Bai Ruoxi looked up at Mu Zhi'an, her eyes filled with tender concern.

Looking at Bai Ruoxi's beautiful face, Mu Zhian nodded and said, "Yi Hao's master, the first head of Canghai Peak."

"Should I be the head of the household...?"

Bai Ruoxi, who frequently visited Canghai Peak during this period, naturally knew this name and muttered to herself with some surprise, "What does she want with you?"

"If I had to say, it has something to do with you too," Mu Zhian said, his gaze sweeping over Bai Ruoxi's curvaceous figure beneath her white dress.

"What does this have to do with me?" Bai Ruoxi tilted her head slightly and looked up at Mu Zhian.

But Mu Zhian did not answer. Instead, he placed one hand on Bai Ruoxi's slender hand and said softly, "I'll tell you slowly tonight. It's so late. Go back and rest early so you don't catch a cold."

Moreover, with the weather so cold, he also needed Bai Ruoxi to warm his hands.

Seemingly noticing that Mu Zhian was looking at something, Bai Ruoxi immediately rolled her eyes at him.

But Mu Zhian didn't mind at all. He glanced at Wei Mengrou, who had gotten up and left the pavilion, and then grabbed Bai Ruoxi's small hand, saying, "Let's go back to our room to rest, Ruoxi."

Noticing the sincerity and gentleness in Mu Zhian's eyes, Bai Ruoxi naturally understood his thoughts. She lowered her eyes shyly and didn't look at him, but let Mu Zhian lead her into the house.

After a while, Mu Zhian lit the candle on the table and looked at Bai Ruoxi, who was sitting on the bed with her legs turned to one side, and her snow-white legs revealed under her skirt.

Bai Ruoxi was about to take off her white ankle socks, but Mu Zhian immediately stepped forward and placed a hand on the back of her hand to stop her.

"Keep the socks." Mu Zhian gazed at the beauty in the plain white dress. A strand of hair fell across her slightly flushed, cool face, giving her a striking, three-dimensional beauty reminiscent of a mixed-race woman.

Bai Ruoxi looked up at Mu Zhian in confusion, blinked, and asked, "Why?"

Mu Zhian said, "They increase attack speed."

Bai Ruoxi tilted her head slightly, not understanding.

Mu Zhian smiled and said, "It's okay if you don't understand... you'll understand in a moment."
