Chapter 928: The Land of Immortal Burial, the Xiyi Nether Realm

The next day.

Immortal Burial Valley.

Gazing at the terrifying mist permeating before him, Qi Yuan's eyes narrowed slightly. Without hesitation, he summoned his phantom body and sent it ahead to clear the path.

Although with his current strength, it was unlikely he would encounter unmanageable danger unless he ventured into the deepest areas of the Immortal Burial Valley.

But as the saying goes, caution is the parent of safety. In a place involving the level of Immortals, it was better to be safe than sorry.

As his cultivation advanced to the Mahayana Realm, the strength of his phantom body also rose accordingly, reaching the same level as his true self.

Of course, according to the System, unless Qi Yuan collected more taiyi true dragon pills, this Taiyi True Dragon phantom body could only reach the Mahayana Peak at most…

On the other side, seeing Qi Yuan effortlessly create a near-perfect Clone, the Howling Moon Celestial Dog couldn't help but click its tongue in wonder.

However, deterred by a certain someone's power, it didn't dare to ask questions and instead silently followed behind.

As soon as they entered the range of Immortal Burial Valley, a bone-chilling cold rushed toward them. The entire world seemed covered in a thick layer of gray haze and rust, and everything within sight appeared obscure and unclear.

Gloomy, deathly still, withered, decaying… being inside the valley was like being in a desolate graveyard, without a single trace of Life Qi.

If it were some cowardly Cultivators, they would probably be scared out of their wits and have their legs turn to jelly before they even began exploring, not daring to take another step deeper.

But a certain someone had once experienced the Great Void, which was hundreds of times more eerie than this place. The scene before him was complete child's play.

Bang!

A Hedao Realm Yao Beast, covered in gray patterns and completely turned into a mad demon, was punched to explosion by the phantom body. Its foul-smelling blood splattered everywhere, but before it could even hit the ground, it was rapidly swallowed by the surrounding mist, appearing as if it had evaporated into thin air.

"Master Qi."

Gazing at the increasingly dense gray mist, the Howling Moon Celestial Dog's dog face showed a somewhat human-like unease as it whispered a reminder:

"This place has already turned into the legendary Xiyi Nether Realm. Living people must never stay here for too long, otherwise, they will gradually have the life force within their bodies drained just like that Yao Beast, becoming mad demon Puppets that are neither alive nor dead."

Hearing this unfamiliar term, Qi Yuan couldn't help but frown and asked:

"What does Xiyi Nether Realm mean? Is it very powerful?"

Facing the inquiry, the Howling Moon Celestial Dog rarely refrained from showing off its glib tongue. Instead, with a solemn face, it explained:

"As the saying goes, people become ghosts when they die, and ghosts become Jian when they die. If an Immortal who lives forever dies, they turn into a mass of Xiyi Qi."

"Since several True Immortals once fell here, a large amount of Xiyi Qi has accumulated over time, forming a Xiyi Nether Realm…"

While speaking, it held its breath, seemingly extremely wary of the gray mist swirling around, and continued:

"Xiyi has no intelligence, yet it remains condensed and eternal. Once a living person is tainted by too much of it, their essence, energy, and spirit will be slowly swallowed, eventually turning them into walking dead controlled by the Xiyi, automatically attacking all living beings that enter the Nether Realm!"

Hearing this, Qi Yuan suddenly realized. No wonder this Immortal Burial Valley was called the head of the three great forbidden lands of the Cultivation World; it was indeed extraordinary.

From the Howling Moon Celestial Dog's tone, one could tell that even in the Immortal Realm, a Xiyi Nether Realm was considered a very troublesome existence.

Of course, as long as the Immortals who died in the Immortal Burial Valley didn't reanimate, no matter how many of these controlled Puppets came, they wouldn't be enough for the phantom body to kill.

Although he wasn't particularly afraid, he still quickened his pace, leading the Howling Moon Celestial Dog deeper into the Immortal Burial Valley.

With the phantom body clearing the dangers ahead, the man and dog were unstoppable, quickly reaching the location marked on the map.

At this moment, the originally sparse gray mist had become much thicker. Within sight, many strange-looking corpses with rotting skin were scattered on the ground, covered in a layer of eerie white, like fallen frost and snow.

After confirming he hadn't found the wrong place, Qi Yuan raised an eyebrow, a hint of surprise appearing on his face.

The ruins before him were much smaller in scale than he had imagined. Rather than an Immortal ruin, it was more like a dilapidated ancient hall, and a somewhat shabby one at that.

In front of the hall was an open space with three shallow pits, obviously where the three test items had been placed previously.

After the three test items were taken away by the three Demon Venerables of the Demon Sect, the site had become empty.

The two doors, which weren't particularly grand or imposing, were bare without any complex decorations. In the very center of the doors, three obvious slots had appeared…

Seeing this, Qi Yuan's gaze narrowed slightly, and a flash of excitement appeared in the depths of his eyes.

As a normal person, he wasn't foolish enough to test the power of the Restriction outside the ruins. Instead, he honestly took out the three keys and placed them one by one into the slots on the door.

The next moment.

Kacha, kacha, kacha—

Accompanied by a tooth-aching, piercing screech of friction, the long-sealed doors swung open, revealing a deep, dark passage.

Unlike the cold and ominous atmosphere outside, the wind blowing from inside the door carried a strange warmth, mixed with a hint of elegant fragrance that refreshed the spirit…

Before Qi Yuan could step inside, the stuttering voice of the Howling Moon Celestial Dog came from beside him:

"Grandpa… Qi… how about you go in alone, and I'll stay here to guard the door…"

"Do you want to die?"

While arranging for the phantom body to go in and explore, Qi Yuan glanced sideways at the stupid dog.

"Don't give me that bullshit, get your ass over here right now!"

Before his voice had even faded, Qi Yuan's heart suddenly skipped a beat, and he instinctively looked inside the door.

In just a few short breaths, he had actually completely lost contact with his phantom body!

Is it this dangerous?

Qi Yuan's expression changed slightly. Without another word, he grabbed the Howling Moon Celestial Dog by the neck and stepped directly through the door…
