The Demon Marrow Crystal was a rare treasure, greatly beneficial for Xu Hei's cultivation of the Heavenly Demon Technique.

Although it had been absorbed by the stone tablet, as long as the Demon God Cauldron was there, slowly refining the stone tablet might allow it to be extracted again.

In this way, Xu Hei's Heavenly Demon Technique, which had seen no progress for a long time, might break through once more.

"Oh? Is there something wrong?" Xu Hei asked.

"The things left behind by the Heavenly Demon Scattered Person are mostly endless disasters. Back then, his cave dwellings were full of traps and mechanisms, with no opportunities at all. Even if there were some treasures, they were meant to trick people," Night Owl said seriously.

"..." Xu Hei was speechless.

After thinking for a moment, he decided to store the stone tablet in the Demon God Cauldron to prevent it from causing trouble.

"You can take it, but let me remind you, if this stone tablet shows any unusual activity, it's best to discard it immediately. Otherwise, I won't save you," Night Owl warned.

"Don't worry, I know what I'm doing," Xu Hei replied.

Li Changge led the Tianhen Sword Sect into the Land of the Moon, likely to avoid the Flame Demon Ancestor.

Huang Tiancheng of the Yan Dao Sect, along with another disciple surnamed Sun, entered the Land of the Sun, while another female cultivator surnamed Hua entered the Land of the Moon.

The same sect splitting up immediately aroused curiosity among the crowd.

"Splitting up? The Yan Dao Sect must have discovered some secret and didn't inform us!" people whispered.

"We should split up too!"

The Sea Star Demon Clan also divided into two groups and entered both passages.

Xu Hei didn't delay any longer, his figure flashing as he rushed into the passage to the Land of the Moon, with Night Owl and Han Te following closely behind.

Xu Hei chose the Land of the Moon mainly to avoid clashing with the Blood Refining Sect. If they ambushed him at the entrance, waiting for him to enter, wouldn't he be walking into a trap?

Without the balance of other sects, he didn't think the Flame Demon Ancestor would kindly let him go.

"Xu Hei has entered the Land of the Moon. What should we do next?" Ji Qing asked through a transmission.

"Is there even a need to ask? The Land of the Moon is perfect for cultivating our Nine Nether Moon Technique. In such a place, our strength won't be affected but will thrive!" Wei Wudao, Ji Qing, and two other black-robed cultivators entered the Land of the Moon together.

…………

"Buzz!"

At the moment of entering the passage, the scenery before them rapidly changed, like entering a different space.

When Xu Hei reappeared, he found himself in a vast, dimly lit passage.

The sky was covered with thick dark clouds, the ground was pitch-black soil, and the light was dim, with gray mist everywhere, making visibility extremely low.

Everywhere, there were fluctuations of restrictions. If one dared to rush in recklessly, it would only lead to death!

"Where are the others?"

Xu Hei spread out his divine sense and took out the communication jade slip left by Night Owl, finding it completely ineffective.

When Xu Hei's divine sense touched the black mist above, he suddenly felt it being absorbed, startling him into retracting his divine sense.

Xu Hei's expression turned serious.

No wonder the communication jade slip was ineffective; these black mists could isolate divine sense.

"It seems that after entering the passage, people are randomly teleported, scattering everyone. In this way, I can only rely on myself to explore," Xu Hei thought to himself.

The three from Yan Dao Sect must have discovered this feature, which is why they entered separately.

Xu Hei activated the Night Demon Wings, concealing his figure as he moved forward.

He didn't recklessly use spirit insects to scout, fearing that triggering any restriction might affect him.

Fortunately, the direction was correct; he just needed to follow this passage forward.

Chilling winds howled from all directions, ghostly wails echoed, and Xu Hei felt as if something in the black mist was watching him, accompanied by a sense of danger, prompting him to keep the Rock Crystal Guardian active to prevent a sudden attack.

"What the hell is that?"

Xu Hei stared at the black mist, not daring to extend his divine sense too far, remaining vigilant at all times.

Fortunately, he hadn't encountered any real danger along the way.

An hour later, Xu Hei stopped, took out a pill to restore spiritual power, and continued forward.

Suddenly, he paused, spotting a plant growing on the open ground ahead.

The plant was entirely black, with slender stems like a blade of grass, only palm-sized, emitting faint green light and a ghostly wind, extremely eerie.

"Yellow Spring Grass!" Xu Hei's face changed.

He stepped forward to investigate carefully, confirming it.

The plant before him was indeed the Yellow Spring Grass, one of the three great Underworld Flowers.

Legend has it that it only grows in places with extremely dense yin energy, at the center where the moon converges, watered by Yellow Spring.

Its value was no less than the exotic treasures at the trade fair, in some sense even rarer than the Ten-thousand-year Cold Marrow!

Previously, the Ancient Tomb Sect had specifically sought Yellow Spring Grass at the trade fair, offering a sky-high price, but to no avail! If they knew the Yellow Spring Grass was here, they'd go crazy.

Without hesitation, Xu Hei released a small team of Thousand Illusion Ants to harvest it, and in the blink of an eye, the ants surrounded the Yellow Spring Grass.

"Something's wrong!"

Suddenly, a strong sense of danger surged in Xu Hei's heart, and he quickly retreated, only to see the Yellow Spring Grass transform into a ferocious mouth, lunging forward.

In a flash, the small team of Thousand Illusion Ants was devoured, along with the ground where Xu Hei stood, leaving a large shallow pit.

When Xu Hei looked again, there was no Yellow Spring Grass in sight.

It was clearly a transparent ghost creature.

The ghost creature flickered between transparency and solidity, containing countless transformations, its appearance unclear, with only a pair of green eyes fixed on Xu Hei.

"So it's a Phantom Yin Ghost!"

Xu Hei's face darkened, thinking, "Judging by this ghost's level, it's at least at the Divine Transformation Stage. This Land of the Moon actually harbors such danger!"

Fortunately, Xu Hei was cautious enough; if he had approached recklessly to harvest, he would have suffered greatly.

The Land of the Moon had existed for countless millennia, and it wasn't surprising that some intelligent ghost creatures had emerged over time.

Of course, a ghost of this level couldn't have appeared without a source, but now wasn't the time to investigate.

The Phantom Yin Ghost transformed into Xu Hei's appearance, charging at him instantly. Xu Hei didn't waste words, directly summoning the Demon God Cauldron to unleash its devouring power.

"Boom!"

The devouring force erupted, drawing in the surrounding yin energy like a storm. The Phantom Yin Ghost let out a piercing scream, its terrifying sound waves crashing into Xu Hei, causing his body to tremble, the Rock Crystal on his surface shattering, but the spider silk armor blocking the divine sense held firm.

At the same time, the essence within the Phantom Yin Ghost was mostly absorbed, its form uncontrollably drawn towards the Demon God Cauldron.

The ghost let out a miserable cry, turning blood-red as it burrowed into the ground, seemingly fleeing, but in reality, closing in on Xu Hei once more.
