Max Out Proficiency, Grind into a Mortal World Sword Immortal

"Rumble—"

The entire hall shook violently, and countless cracks appeared in the walls. Yun Shu's expression changed as he quickly shielded Yuan Chen and Yuan Ling behind him.

"What's happening?" Yuan Ling asked, a hint of wariness flashing in her eyes.

Yun Shu shook his head. "I don't know. But it can't be anything good."

Just then, a cold voice came from outside the hall:

"Remnants of the Immortal Clan, surrender now!"

Yun Shu frowned. He had never heard the voice before, but the powerful aura it carried made his heart flutter with unease.

"Careful!" Yuan Ling suddenly said in a low voice. "That's the aura of the Ancient Outer-world Tribe!"

Yun Shu was startled. The Ancient Outer-world Tribe had actually found them here!

"Yuan Chen, Yuan Ling, stay behind me," Yun Shu said gravely. At the same time, Chaos Power surged wildly within him, enveloping his body in a gray-white radiance.

The hall's doors shattered with a crash, and a black figure rushed inside. It was an old man in a black robe, his face sinister and his eyes gleaming with greed. A powerful aura radiated from him—he was even stronger than Xiao Tianyan by several degrees!

"The Ancient Outer-world Tribe..." Hatred flashed in Yuan Ling's eyes. "So it really was you!"

The black-robed old man laughed loudly. "That's right, it was us, the Ancient Outer-world Tribe! I can't believe remnants of the Immortal Clan are still alive. Today, I'll wipe you all out in one fell swoop!"

With that, the black-robed old man formed hand seals. Black energy surged around him, transforming into a gigantic black python that roared as it lunged at Yun Shu. The moment it appeared, the entire hall began to shake. Space shattered inch by inch, as if it might collapse at any moment.
