"The Ballad of Cloud Steps": Su Qinghan was always slow in practicing her body skills, but on a rainy night she found that the water she stepped on did not stick to her shoes. She practiced walking according to the trajectory of raindrops. Three years later, her figure was so fast that it left an afterimage. When the Sutra Pavilion was stolen, she only used a stick of incense to catch up with the thief, and the other party didn't even see her movements clearly.
