Before his death, the master only left Xie Tingzhou half a fish charm and one last word:
"Go to Yong'an and don't let the floating sword come out of its sheath."
But when he stepped into this mountain city, which was called "Floating Country" in ancient times, thirteen waterkeepers had been killed one after another, and the old case of the flood eighteen years ago was also reopened. The Blackwater Alliance blocks the waterway, government files are mysteriously stolen, and the legendary Floating Sword quietly awakens in a heavy rain that has never happened in a century.
It's just that no one knows——
Once the sword is unsheathed, the first thing to be submerged is Yong'an City or the truth that has been hidden for eighteen years.
