The First Sword Emperor.

Summary

With the seal broken, a black mist engulfed everyone, prompting Su Hun to rally the group to purify it. As they fought against the mist and its shadowy figures, Su Hun realized a demon was about to emerge. He instructed those below a certain level to form a barrier while leading stronger allies into battle. They faced overwhelming numbers of ferocious creatures, but their combined strength began to thin the mist. Eventually, a throne appeared, revealing a powerful figure who mocked them, indicating a strength beyond their own.
