The Primordial Demon Lord looked at the dim name on the jade tablet, and his face darkened a few shades.
"Who could it be that even Qi Yao is no match for?" The Primordial Demon Lord murmured, frowning.
He glanced into the great hall, waved his arm, and a circle of black light, like water, spread out around him, quickly exploring the entire hall.
The traces of battle here had been erased, leaving not a single hint behind.
At that moment, a spot of blue light suddenly appeared in a corner of the hall.
The Primordial Demon Lord raised an eyebrow, and then his figure flickered over.
With a wave, he summoned the blue light into his hand, revealing a small fragment of blue stone the size of a fingernail.
"Ink Crystal Jade?" murmured the Primordial Demon Lord as a black light emanated from his hand, enveloping the blue fragment.
Besides this blue fragment, nothing else was left in the hall.
