Underworld Reincarnation Domain, the Divine Artifact Underworld King Sword!

"Stop the train! Stop the train!"

Upon seeing the scene before him, the train conductor was stunned for a moment before immediately shouting in a low voice, while simultaneously operating the driving Soul Tool in front of him.

If it were to fall, it would be highly unlikely that any of the passengers on the train would survive; it would be a complete and utter disaster.

"Sizzle! Sizzle!"

Despite the sudden braking, the Soul Guidance Train did not stop immediately but continued forward, sparks flying between the train and the rails, accompanied by a series of ear-piercing friction sounds.

"Train conductor, look what that is!"

At this moment, the same train conductor pointed ahead again, but this time his voice trembled slightly.

"What's wrong now! Stop the train immediately!"

Overwhelmed with emotion, the train conductor almost roared, but the moment he looked up, he froze, his hands stopping in their tracks.

"Waaaaah!"

The mournful cries of the dead echoed from afar. The sky in front of the train had turned gray at some point, reflecting the red light of the previous explosion. A pale gray hue continued to spread and cover downwards, and all sounds seemed to disappear under that gray cover.

The violent explosion didn't travel far; it abruptly ceased under the gray hue, and all color vanished at that moment. Gray ashes drifted through the air, as if mourning the dead, or perhaps welcoming the arrival of a king.

Immediately afterwards, the ground shook, space churned, and one by one, crooked figures began to emerge from the gray space, swaying and staggering towards the train.

These figures were none other than countless skeletons, zombies, and various kinds of undead Soul Beast, and under their protection, a powerful figure appeared from the front.

He rode a four-meter-tall Hell Steed, his cloak fluttering behind him, and a gray, transparent cross-shaped Cross Sword at his waist. The entire gray Source originated from him.

"What is this? And who is he?!"

The train conductor was so shocked that he couldn't speak, and could only stare blankly at the figure approaching their train.

With a single stride, the Hell Steed Hell Steed charged toward the Soul Guidance Train. Although its body was enormous, its speed was incredibly fast, and it arrived before the Soul Guidance Train in the blink of an eye.

The train conductor and attendants kept their eyes tightly shut, afraid to watch what was about to happen. They dared not gamble on whether their Soul Guidance Train was more sturdy than the defenses of this Hell Steed.

But a second later, the collision that the two had anticipated did not occur. Just before they hit the Soul Guidance Train, the towering Hell Steed suddenly turned to ashes and vanished, while the tall figure seemed to traverse space, taking a light step forward and directly entering the Soul Guidance Train.

And their train came to an abrupt stop upon entering that gray area, refusing to move forward even an inch.

Good news: their Soul Guidance Train has stopped, so they don't need to chase the plane anymore. Bad news: a powerful individual, suspected to be Evil Soul Master, has entered their Soul Guidance Train.

"This... this... are you a human or a ghost?!"

The train conductor swallowed hard, looking at the dense swarms of undead creatures outside the train and the person in front of him, and asked haltingly.

"So, do I look more like a human or a god?"

The figure glanced sideways at the man, raised an eyebrow, and asked.

"Sorry, sorry, that's silly. You're busy, you're busy."

The train conductor quickly covered the train attendant's mouth, pulled him aside apologetically, and thought, "He's obviously not a good person. Talking now is practically suicide!"

"Oh! This power that transcends all constraints, it seems we really didn't make a mistake coming here this time." A deep voice sounded, sweeping past like a cold wind. The figure ignored the two and took a light sniff of the air.

This person was none other than the Underworld Emperor.

Then, the Underworld Emperor' gray eyes seemed to pierce through the layers of carriages, looking straight at a certain carriage behind, a rare glint of fervor flashing in his deep gaze.

Because at this very moment, he discovered a power that transcended the constraints of this world!

"Although I don't want to get involved, you are, after all, a member of the Holy Cult's high-ranking officials. Moreover, I'm just curious to see what this level of power is all about."

The Underworld Emperor's pale hand gripped the Cross Sword at his waist, and a terrifying pressure suddenly Advent. Clusters of gray flames burned on the Cross Sword, and a chilling, ethereal aura permeated the air.

"Eternal Sigh of the Underworld, Underworld King Sword!"

"The Underworld Reincarnation Domain, the cycle of life and death!"

The Underworld Emperor raised the Cross Sword in his hand, and a gray hue covered the Cross Sword beneath his feet, making the burning gray flames even more intense. A deadly aura pointed towards a certain carriage behind him.

The Cross Sword in the hands of the Underworld Emperor is a divine weapon called the Underworld Sigh, also known as the Underworld King Sword. The surrounding area is the Underworld Emperor's innate Martial Soul domain, Underworld Rebirth!

"Buzz buzz buzz!"

Space trembled, and the aura on the Underworld King Sword seemed to reach a critical point. With a gray tail, it shot out fiercely, piercing through the metal, sweeping across space, and disappearing in an instant.

"Huh? There are Evil Soul Master too?"

Inside the carriage, Tang Wulin, who was being controlled by Tang San, narrowed his eyes and suddenly looked in one direction. In the next instant, a Cross Sword covered in gray flames suddenly slashed down, its target being the azure light.

"Bite!"

Just as the Underworld King Sword collided with the object, a crisp ringing sound rang out. Immediately afterward, the flames burning on the Underworld King Sword seemed to have encountered something indescribable, and were extinguished by more than half in an instant. However, the azure light also stopped, and in an instant, it Entanglement the Underworld King Sword, emitting a piercing corrosive sound.

"I'm still alive..."

"This is the Underworld King Sword of the Underworld Emperor!"

The Dark Bell fell to the ground. Seeing the scene before her, a flicker of emotion flashed in her dark red eyes. Painful memories of the past receded like a tide. She immediately dragged her restrained body away with difficulty towards one end of the carriage.

"Who? The Underworld Emperor?!"

Upon hearing this, Jiang Xiu, who was hiding in the shadows, was suddenly startled. Looking through the gap left by the Underworld King Sword, he saw a gray figure rapidly approaching his carriage.

"No way, what kind of insane matchmaking system is this?!"

Jiang Xiu clicked his tongue, his thoughts churning. He had originally intended to waste Tang San's divine sense to make a move, but now he had attracted so many powerful figures, including the Underworld Emperor who had disappeared for nearly a hundred years!

"That's good, the more chaotic the better. Maybe this time we can obliterate Tang San's chance to attack, along with this wisp of his divine consciousness!"

Jiang Xiu's eyes hardened, and he thought to himself.

But then, Jiang Xiu suddenly noticed that the Dark Bell, whose power had been suppressed, was directly in the direction of the Wriggler, heading towards him.

"Hey! The Dark Bell isn't out of the question... How about saving it, and then infiltrating the Holy Spirit Cult..."

Jiang Xiu's eyes lit up, but in order not to attract the attention of Tang San and the Underworld Emperor, he did not make a move immediately, but silently watched.

"Tap tap tap."

The Underworld Emperor's figure flickered, and in an instant he arrived at this carriage, surrounded by gray ash that devoured the life force in the space.

"It seems you are the key to my breakthrough from the God Level."

The Underworld Emperor raised his hand and beckoned the Underworld King Sword, his eyes burning with desire as he looked at Tang Wulin. If he could refine this person into his Underworld Reincarnation Domain, he would gain the power within this young man.

Although he didn't know how a teenager could possess God Level power, refining it would definitely be the right thing to do.

"A mere ant dares to covet such things; it truly doesn't know its own limitations!"

"It just so happens that I still have some God King Divine Power left from this attack, so I'll use it to bury you!"

Tang San's eyes were icy cold as he slowly raised his Golden Trident. The Four-Word Battle Armor on the Underworld Emperor's body also instantly shone brightly. He gripped the divine artifact Underworld King Sword tightly in his hand, and a faint, mysterious light flickered in the gray crystal between his brows, as if it contained something.

He could tell that this person's power was only temporary, and he was absolutely unwilling to give up this opportunity. Moreover, he had a major trump card up his sleeve, so he was not afraid at all.

Therefore, although the opponent was strong, his sword was not necessarily at a disadvantage!

The Underworld Emperor is determined to refine this young man; no one can change his mind!
