After graduating college, Wei Ran was whisked into an unseen realm by a mischievous cat. While searching for a way back, he learned that the only train capable of ferrying him home would not depart until six months later. Until then, he could only stay briefly in Mao Mao Yaya"s shop—Guaixiang Sale. Just as routine began to settle, Wei Ran realized that dragon scales manifested wherever he went, each appearance unleashing an effect. It baffled him; no matter where he traveled, the scales would surface, and when they appeared, a new strange effect erupted—often a gust of wind, sometimes a ripple in the air that made clocks run backward.
