Yanshuidu

Judging from the protagonist's setting, plot elements and background, this is an ancient romance and humanities genre, and more specifically can be classified as a sub-genre of "ancient romance + Jianghu/Chaotang undercover". The core is centered around the reunion of Nan Shuiwen and Lu Zhongjin's old love, with the emotional changes between the two people ten years ago as the core clue; at the same time, it is interspersed with the suspenseful undercurrent of "smuggling ordnance by water transport", which has both emotional tension and plot conflict. It is not a simple sweet pet or sadomasochism, but a realistic adult romance story in ancient times.
