This was a pitch-black and deathly silent wasteland. A black-colored demonic mist rose, filled with evil. In the center, there was an incomparably large black sacrificial altar, emitting a terrifying aura.

The altar was filled with spirit inscriptions that continuously sparkled. A jade-white soft light circulated and a sealing power suffused out.

Even so, black demonic aura still continuously seeped out from below the altar, clashing against the dazzling white light and forming a strange scene.

Swish!

Space distorted as three figures landed on the desolate plains in a sorry state.

"This …"

Just as Qin Feng wanted to curse, his eyes landed on the strange black sacrificial altar. He felt a terrifying aura being faintly emitted from within. His body involuntarily trembled as he looked around vigilantly.

Seeing the thick demonic aura, his scalp couldn't help but tingle. If not for the protection of Lingyun's Holy Light, his consciousness would have already been corroded by the demonic aura.

The altar was very high, with ninety-nine steps leading to the top.

Lingyun looked at the black altar, his eyes slightly focused. Even though there were spirit tattoos blocking the way, he could still feel the powerful energy fluctuations coming from the altar.

Once that power was released outside, even if it was just a small remnant of it, it would be enough to take the lives of the three of them.

"Let's go!"

Ling Yun hesitated for a moment, then shouted in a low voice. Up to here, there was no turning back, his body was surrounded by the golden sacred light, and was flying towards the altar with Ling'er and Qin Feng.

A few minutes later, the three of them arrived near the altar and stopped in their tracks. After such a close contact, the three of them discovered that the black altar was even larger than they had imagined.

At the top of the altar, there were five ancient stone pillars covered in the mottled marks of time. The five stone pillars were all different, and they were all Five Spirit Stones. Powerful Spiritual Energy fluctuations radiated from them, giving people a feeling of trepidation.

The five stone pillars were connected by a mysterious aura, almost as if they were one entity.

The green dragon that bared its fangs and claws, the white tiger that roared with its bloody mouth, the Vermillion Bird that burned with the flames of Nanming, the Black Tortoise that sat atop the Netherezim Black Sea, and the qilin.

The illusory image of the five spirits appeared out of nowhere. The energy of the five elements permeated the air. They were born together and repressed each other, while the energy of the great Dao permeated the air.

However, Ling Yun and the other two could not help but look towards the center of the altar as their bodies trembled.

Over there, it turned out to be a huge gray coffin. This coffin was not placed horizontally on the altar, but vertically and vertically. More than half of it was located on the altar, and from its appearance, it seemed to have rushed out from the altar.

Ling Yun saw that on the altar, which seemed to be an undying altar that was tens of thousands of years old, there were a few cracks extending downwards.

There were five stone pillars shooting out the power of the five elements, which then transformed into a five soul seal to bind the sarcophagus.

The sarcophagus was strange, or more accurately speaking, its existence was strange, it had black energy, and from Ling Yun's senses, the sarcophagus was like a black hole, devouring all auras. Even if his consciousness approached it, it would be devoured, and it was extremely evil.

Above the stone coffin, there was also black flames that were intertwined with the Five Elements Chains, resisting the corrosion.

"Demon Emperor!" Lingyun looked at the gray sarcophagus, and felt the demonic Qi that was being emitted, he clenched his teeth and said softly, with a strong sense of fear in his eyes.

"Is there a Demon Emperor sealed inside the sarcophagus?" Ling'er's expression also became ugly. She wasn't sure if they would still be able to leave here alive. The Demon Emperor's strength had far surpassed her imagination.

Even if they were Martial Emperors of the same level, it would still be difficult for them to kill the other party. Instead, they would choose to seal him and use the passage of time to erase him.
