The scene in his memory was atop a towering mountain that pierced the clouds.
A solitary figure sat suspended above a massive boulder.
Cold wind swept up fallen leaves and brushed past the figure's graying temples.
The figure suddenly rose, his steps light as he walked straight upward, strolling among the clouds.

The Blackwater Artifact Spirit's eyes widened in utter astonishment.
It had never expected Lin Yi to grasp the prototype of the Emperor Law
