The garage, well-maintained and regularly cleaned, was brightly illuminated, showcasing an array of luxurious cars gleaming under the light. However, Yang Chen paid no heed to these symbols of wealth. He walked straight to a corner of the garage and reached for a particular brick on the wall.

From within, Yang Chen retrieved a palm-sized black box, which shimmered under the light with its unique pattern.
"This thing really does bring trouble," Yang Chen muttered to himself, a wry smile on his face. He carefully opened the box to reveal a black cloth, holding a transparent crystal the size of a pinky finger, displaying a mysterious black sheen.
