Summoning the Gods: Start by creating the Eternal Night.

The Nine Nether Abyss, the Demon Sect's main hall.

Black mist swirled around them, and the flickering candlelight illuminated the figures of Xue Wutian and Mo Tianchou.

Xue Wutian sat upright in the side seat, his scarlet eyes filled with a hint of solemnity as he looked at Mo Tianchou in the main seat.

"Tianchou, the secret realm of the Fallen Immortal Mountains is about to open. Whom do you plan to send?"

Upon hearing this, Mo Tianchou pondered for a moment before slowly speaking:

"Uncle-Master, the secret realm is only accessible to cultivators at or below the Nirvana Realm. Within the sect, those who meet the requirements are led by the remaining four Nirvana Realm guardians among the eight guardians."

"Black Wind, Hundred Nights, Wind's Silence, and Crimson Dream—these four are the strongest and most experienced, enough to dominate the secret realm."

He paused, then continued, "Adding the holy sons and core inner disciples of the sect, the manpower for this trip will be about right."

"Furthermore, although Chi Yuan and Ming He have just recovered from their injuries, their cultivation has already recovered to about 70-80%. I plan to have them secretly follow me."

"Firstly, we can provide support from the outside, and secondly, we can provide timely assistance should anything change in the secret realm."

Upon hearing this, Xue Wutian nodded, a profound meaning flashing in his scarlet eyes:

"Sure. But you must tell them that once they enter the secret realm, their primary task is to find my elder brother and investigate any clues related to him."

"As for those so-called opportunities and inheritances, let's put them aside for now and not lose sight of the bigger picture for the sake of small gains."

For him, finding the whereabouts of the Blood Demon Ancestor was far more important than any secret treasure.

"Don't worry, Uncle-Master," Mo Tianchou replied with a bow.

"I will definitely remind them repeatedly to make finding the ancestor their top priority."

"I will also have Chi Yuan and Ming He keep an eye out for any trace of the Ancestor on the outskirts."

Xue Wutian nodded in satisfaction: "That's excellent. If we can find clues about my elder brother in the secret realm, perhaps... we can solve the mystery of his disappearance."

The two exchanged a glance, their eyes filled with anticipation and solemnity. After three thousand years of searching, this might be their closest chance to the truth.

Meanwhile, in the Imperial Palace of the Great Qian Dynasty, at the Zichen Hall.

Qian Tian sat upright on the dragon throne, his face still showing some weariness from the pain of losing his son, but his eyes were exceptionally sharp.

Four people stood in the hall—the eldest prince Qianfeng, the third prince Qianming, and four Nirvana Realm worshippers from the offering hall.

"Father (Your Majesty)!" the four of them bowed in unison.

Qian Tian waved his hand and said in a deep voice, "I summoned you here because of the matter of the secret realm of the Fallen Immortal Mountain Range."

He glanced at everyone and continued, "The secret realm will open in seven days, and only cultivators at or below the Nirvana Realm can enter."

"The Ancestor sensed that there might be residual traces of the Great Ancestor's aura within the secret realm, and perhaps... even clues to the Great Ancestor's disappearance."

A flicker of excitement flashed in the eyes of the eldest prince, Qianfeng: "Father, are you saying that the founding emperor might be related to that secret realm?"

"It's highly likely." Qian Tian nodded, his tone grave.

"Your primary task for this trip to the secret realm is to search for traces of the Great Ancestor and find any clues related to him."

"If you can find the legacy or tokens left by the founding emperor, I will award you a great merit."

The Third Prince, Qianming, was even more impatient and quickly said, "Father, rest assured! Your son will do everything in his power and will not let any clue slip by!"

The four attendants bowed and said, "We will certainly assist the two princes and fulfill His Majesty's entrustment!"

Qian Tian nodded in satisfaction: "Very good. The First Prince is composed, and the Third Prince is brave. The two of you must cooperate with each other and not act impulsively."

"The four servants are very experienced, so we need to take good care of them."

"Furthermore," Qian Tian's tone turned cold, "the Blood Demon Palace and the Nine Nether Demon Sect will definitely send people to the secret realm, so you need to be extra vigilant."

"If you encounter them, avoid them if you can. If you cannot avoid them, do not hesitate to fight back, but remember not to let fighting interfere with your business."

"Your subject obeys!" the crowd replied in unison.

Qian Tian waved his hand: "Go. Prepare immediately for the Fallen Immortal Mountain Range. Be careful."

"yes!"

After bowing, the eldest prince, the third prince, and the four attendants turned and left the Zichen Palace.

Inside the hall, Qian Tian watched their departing figures, a complex light flashing in his eyes.

He slowly rose, walked outside the hall, gazed towards the direction of the Fallen Immortal Mountains, and murmured softly, "Great Ancestor... I hope you are truly in the secret realm..."

The main peak of the Qingyun Sect is the Qingyun Hall.

Sect Master Xuanxiaozi sat upright in the main seat, dressed in a moon-white Daoist robe. His face was thin and his eyes were calm as water, yet he exuded an air of majesty.

Your Highness, the Vice Sect Master (Yun He), the Second Elder (Zhong Xiang), and the Fifth Elder (Ge Liang) stood with their heads bowed, their expressions solemn.

"You are all aware of the secret realm of the Fallen Immortal Mountain Range."

Xuanxiaozi spoke slowly, his voice not loud, yet it clearly resonated throughout the hall.

"This trip to the secret realm will be led by the Vice Sect Master, with the Second Elder and the Fifth Elder accompanying us."

His gaze swept over the three: "The Vice Sect Master's cultivation has reached the late stage of the Celestial Realm, the Second Elder is at the peak of the Nirvana Realm, and the Fifth Elder is at the late stage of the Nirvana Realm. With the three of you here, as long as you don't actively provoke top-tier forces, you should be safe."

"In addition, select fifty core disciples to go together."

Xuanxiaozi added, his tone carrying a hint of warning.

"Let them go out and gain experience, broaden their horizons."

"In recent years, the sect has been stable, and some of the younger generation have become too arrogant. They always think that Qingyun Sect is the best in the Eastern Region, so they look down on everyone."

"This is a good opportunity to show them how vast the Eastern Region is and how many powerful individuals it has, far surpassing anything found within any sect."

The deputy sect leader bowed and replied, "Sect leader, rest assured, we will definitely restrain our disciples and ensure they do not cause any trouble."

The Second Elder and the Fifth Elder responded in unison, "We will follow the Patriarch's instructions."

Xuanxiaozi nodded slightly, a hint of worry flashing in his eyes: "With the opening of this secret realm, all the major forces in the Eastern Region have gathered, making it a mixed bag."

"The Bloodstained Palace and the Nine Nether Demon Sect have reappeared, making the situation unpredictable."

He paused, then emphasized, "Our Qingyun Sect recently had a conflict with the Xiyu Tower, resulting in the loss of two Nirvana Elders. We have not yet fully recovered."

"During this journey into the secret realm, safety is the top priority. Do not easily get involved in the conflicts between any parties. If you can obtain an opportunity, all the better. If not, just ensure the safety of yourself and your disciples."

"Yes!" The three accepted the order once again, understanding their sect leader's considerations. The Qingyun Sect truly should not make any more powerful enemies now.

At the same time, at the Xuanming Sect's headquarters.

A black wind howled, and the candlelight inside the hall flickered like will-o'-the-wisps.

The cult leader sat atop a throne of bones, his voice hoarse and grating.

"The Fallen Immortal Realm is not to be missed. Vice Sect Leader, you, along with the Second Elder and the Fourth Elder, will lead a team of thirty sect members there."

The vice-leader, dressed in a black robe, bowed and accepted the order: "Your subordinate obeys. Does the leader have any further instructions?"

The cult leader sneered and continued:

"Hmph! Those bastards from the Qingyun Sect will definitely send people to the secret realm this time. If we encounter them, we need not hold back."

"As for other forces... act according to circumstances, seize what you can, and don't tarnish the reputation of my Xuanming Sect."

The vice-leader bowed and said, "Rest assured, Master, I will not fail in my mission and will certainly obtain the treasures of the secret realm for our sect!"

A fierce glint flashed in the eyes of the Second Elder and the Fourth Elder, who responded in unison, "We swear to serve you to the death!"

The Xuanming Sect Leader waved his hand: "Go. Return as soon as possible."

"Yes, sir!"

The three bowed and took their leave, their figures quickly disappearing outside the hall.

In various parts of the Eastern Region, the secret realm of the Fallen Immortal Mountain Range is about to open.

Whether it was top-tier sects, first- or second-rate forces, or even independent cultivators, they all dispatched teams to head towards the Fallen Immortal Mountain Range.
