Those three treasures were useful not only to the Ghost Clan but also to the Human Race. That was especially true for Liu Wuxie. If he could refine the three treasures, he would be able to reach the fifth-level Heavenly Immortal Realm.

The breakthrough would further increase his chances of victory against Gan Xingzhou and the others, provided they did not make any breakthroughs inside the Sacred Astral River Scroll. The Sacred Astral River Scroll possessed countless treasures, and they had likely seized many of them by relying on their cultivation.

After waiting for about fifteen minutes, the yin energy released from the Divergent Spring Hall greatly weakened.

Deng Jun and Shi Minghuo moved at once. They walked up the hall and stood on the triangular structure.

Liu Wuxie followed behind them, and Tang Yang did as well. This would ensure that they could look after each other if anything unexpected happened.

"This is strange. Since this is an ancient tomb, why is there no coffin?" Cultivators looked down, only to find the ancient tomb empty. They could only see a terrifying amount of yin energy gushing out from below, along with two corpses that had turned into ice sculptures.

Shi Minghuo and Deng Jun both looked confused, wondering if this was a cenotaph. But who would spend so much effort gathering Gloomwood, Yellow Springs Water, and Limitless Ice to build a Divergent Spring Hall there?

Deng Jun took the initiative to enter.

Liu Wuxie quietly released the Sky Devouring Divine Cauldron to collect the two deceased immortals' interspatial rings. By the time the other immortals came over, the interspatial rings had already vanished.

Although everyone here had reached the Immortal Realm, they were no different from mortals inside the Sacred Astral River Scroll. The scroll's internal world resembled a miniature celestial realm, where heavenly immortals were no different from mere ants.

"Look over there!" An immortal walked up to a corner, where they discovered faint cold energy seeping up from below.

"Ma Heng, what did you manage to find?" Several immortals approached and asked.

"There should be another entrance here that leads underground."

The Sacred Astral River Scroll had formed an independent world of its own, which meant the underground was vast. The ancient tomb likely lay buried beneath.

Someone immediately took out a shovel and began digging.

With a loud collision, the shovel in his hand snapped when it struck the hard stone. Anyone could tell that the shovel was no ordinary item but rather a quasi-immortal artifact, only one step away from becoming an immortal artifact.

The owner of the shovel looked distressed. He had lost an artifact before he could even obtain any treasure.

"There's really something strange going on here!" Everyone gathered around and guarded against one another to avoid possible sneak attacks.

The ghost immortal stepped forward and stood on a rock.

"Everyone, work together to lift this boulder!" the ghost immortal commanded. The others stepped forward one after another without delay.

Liu Wuxie walked in another direction, attempting to scan underground with Ghost Pupil, only to frown slightly. He had received an alert from the Heavenly Dao Book that there was a treasure beneath, but it had also warned him of the danger lurking below. Then again, danger and opportunity often coexisted.

"You, come over here!" Five or six people gathered around the boulder, trying to pry it open, only to find it firmly lodged in the ground.

The ghost immortal had yelled at Liu Wuxie, ordering him to come over and help as well. Their cultivation was suppressed inside the Sacred Astral River Scroll. The power everyone could unleash was no different from the Transcendent Realm.

"You're calling me?" Liu Wuxie frowned. Ghost Pupil had just discovered something underground when the ghost immortal interrupted him. 𝒇𝙧𝙚𝓮𝔀𝓮𝒃𝙣𝓸𝒗𝒆𝒍.𝙘𝒐𝒎

"Yes, you!" the ghost immortal said, his eyes radiating a terrifying chill. As an eighth-level Heavenly Immortal, he possessed the highest cultivation among the group aside from Deng Jun and Shi Minghuo.

Shi Minghuo and Deng Jun merely watched from the sidelines with faint smiles, neither helping nor stopping the ghost immortal.

"Why don't you do it yourself?" Liu Wuxie replied with a smile. The ghost immortal had commanded others to move the boulder, but he stood to the side and watched.

When the ghost immortal heard Liu Wuxie's reply, he flew into rage, vanished, then reappeared before him without warning.

"Since that's the case, you can die then!" the ghost immortal said, unleashing a ghost claw that appeared before Liu Wuxie.

He had attacked at the slightest disobedience. Then again, the Ghost Clan and the Human Race were mortal enemies who could not coexist. The human immortals tolerated his oppression only because his cultivation level was higher than theirs.

However, Liu Wuxie had reached the fourth-level Heavenly Immortal Realm. Even a second-level High Immortal would pose no threat to him, let alone this ghost immortal.

"Get lost!" Before the ghost claw could get close to Liu Wuxie, he kicked at him with a tricky trajectory.

The ghost immortal could not dodge in time and curled like a cooked shrimp as he flew out.

"You've got a real death wish, don't you?" Liu Wuxie asked, as though he had done something ordinary after sending the ghost immortal flying with a kick. He did not even use any immortal energy and merely relied on the power of his physique. After all, using his immortal energy would expose his identity.

The cultivators around them looked shocked, including Deng Jun and Shi Minghuo, who scanned him with strange looks. After all, it shocked everyone that a mere fourth-level Heavenly Immortal had sent someone at the eighth level flying with a kick.

When the ghost immortal got up from the ground, he instinctively wanted to attack, only for Liu Wuxie's gaze to force him back. He knew that if he continued to attack, Liu Wuxie would not just send him flying with a kick. He would kill him outright.

"Everyone, let's hurry up and find a way to move the boulder," Ma Heng said, hunching his shoulders and hollering to the other immortals, not daring to provoke Liu Wuxie.

Tang Yang also joined in as seven or eight immortals worked together, making the boulder creak.

Too much time had passed, and the boulder had come loose after the Sacred Astral River Scroll suffered repeated impacts.

Murderous intent surged in the ghost immortal's eyes. He had no intention of letting this grudge pass, and he believed he had merely been careless earlier, allowing Liu Wuxie to ambush him.

In an actual fight, the ghost immortal would not even fear a ninth-level Heavenly Immortal.

More creaking sounds echoed from the boulder as it began loosening. Everyone exerted force together and moved the boulder aside, revealing a hole more than a meter wide.

Terrifying yin energy surged from the hole, but everyone avoided it in time and prevented a direct impact.

They waited for about fifteen minutes, allowing the yin energy to dissipate slightly before growing restless again. The ghost immortal moved first, vanishing from sight and entering the hole.

"Let's go down!" The others followed behind into the hole.

This time, Tang Yang waited and turned to look at Liu Wuxie, seeking his opinion.

Liu Wuxie nodded, telling Tang Yang they could enter but had to remain cautious.

Deng Jun glanced at Liu Wuxie. For some reason, he found the latter familiar, but he could not recall where he had seen him before. He also grew wary of the power Liu Wuxie had displayed earlier and did not dare to act recklessly. He had secretly contacted Gan Xingzhou and the others, who were already on their way over.

Before they descended into the mortal realm, the ancestors had told them to kill a thousand rather than risk letting one escape. According to Gan Xingzhou's plan, he intended to kill every cultivator who had entered the Sacred Astral River Scroll.

In the end, Deng Jun did not act and entered the hole with Shi Minghuo. Only Liu Wuxie remained above now, withdrawing Ghost Pupil before entering the hole with them.

Howling wind roared past his ears when he descended into the hole, and the fall lasted several breaths before his feet touched the ground. The moment he landed, yin energy surged toward him from the surroundings.

Everyone found themselves in a gray hall, with everything pitch-black around them. They could barely make out the rough outlines. The hall was empty, with nothing inside, like an empty cavern.

The surrounding walls were forged from hard rock, making them impenetrable to ordinary immortals.

"Everyone, search the place quickly! There must be an entrance to the ancient tomb," Ma Heng said.

Liu Wuxie caressed the stone wall, which bore many exquisite patterns resembling a landscape painting. These patterns did not seem to have been engraved by a man's hand. Instead, they looked more like a woman's embroidery.

Everyone searched for a long time and found nothing. Several cultivators gradually grew restless, and they took out their artifacts to attack the surrounding stone walls, hoping to carve a path.

Sword rays flashed and fell onto the surrounding wall, producing loud sparks. The stone walls stood unmoving, and the attacks left not even a mark behind.

"So much water!" Right then, water began seeping up from the ground, soon reaching their ankles.

The sudden appearance of the water startled everyone, especially since the water was so cold that even immortals could barely endure it. Several people had already begun shivering from the cold, looking as though they might freeze at any moment.

"Hurry up and find a way out!" Several immortals grew afraid and urgently wanted to leave this place.

However, they soon discovered a real problem. They were only slightly stronger than mortals after entering the Sacred Astral River Scroll, and their means as immortals were completely useless here.

The Sacred Astral River Scroll was a miniature celestial realm, possessing identical laws. This meant that without reaching the Origin Immortal Realm, no one would be able to fly, and they would not be able to fly up to the opening.

The entrance they had jumped down from was roughly ten feet tall. They could easily reach that distance with a simple leap if they had been in the outside world, but jumping such a height was nothing but a fantasy inside the Sacred Astral River Scroll.

Even Deng Jun's and Shi Minghuo's faces turned dark. They clearly had not expected this outcome.

"Are we going to die here?" Several people began sobbing. They had lived for countless years and had not expected to die in such a manner.

"Wuxie, do you have a way to leave this place?" Tang Yang asked via divine sense transmission, ensuring no one else could overhear their conversation.

"We can follow the current up once the water reaches the ceiling," Liu Wuxie said. He could not help but shake his head as he watched these dignified immortals panic.

As the water rose, it would eventually carry them out of this place, and he could not comprehend why they were panicking.

Tang Yang's eyes lit up upon hearing that. Why had he not thought of that?

Then again, everyone had become anxious, which was why they ignored something so basic. As the saying goes, the more complicated something becomes, the further it strays from the truth.

As more water seeped from the ground, the water level soon reached their waists. The attacks on the surrounding wall had likely triggered a spiritual array, causing water to pour out.

When the water was about to reach their necks, the massive chamber began trembling violently, as if struck by a mysterious force. The tremor knocked everyone around, leaving them dizzy, including Liu Wuxie, who firmly guarded his primordial spirit.

The force had come from deep underground.
