Shen Qingwu, the "Thousand Faces" leader of the intelligence organization "Tingting" who stirred up the world in the past and had countless secrets, got tired of intrigues and cheated his way out. She used the pseudonym "A Wu" and lived on the "Floating Boat", a mechanism boat that was insignificant in appearance but had hidden secrets. She was drifting in the vast Jinghu Lake system and just wanted to be an idle boat girl for the rest of her life.
However, the peace was broken by a strange "Jinghu Bride's Corpse Case". The unique mark on the victim actually points to the past she had deliberately forgotten and the mystery surrounding the demise of "Tingting". What makes her even more alarmed is that the clues left at the scene seem to be related to her sister who has been missing for many years and whose life or death is unknown.
In order to trace the whereabouts of his sister and uncover the truth behind the demise of "True Listening", Shen Qingwu had to regain the disguise skills and insights of "Thousand Faces" and drove the floating boat back into the whirlpool of the rivers and lakes. She deals with former enemies, suspicious officials, and mysterious medical seekers, using Fang as her base to solve a series of bizarre and unsolved cases: the theft of secret treasures from aristocratic families, murders caused by curses in ancient tombs, and mysterious comic strips... Every time she solves a case, she gets closer to the truth, but she also gets deeper into power struggles and emotional entanglements. The floating boat is no longer a haven for her to escape from the world, but a lonely boat sailing towards the center of the storm of fate. Can she find a balance between the shadows of the past and the new bonds, protect everything she cherishes, and find a true "floating life" for herself?
