In Shanghai in the 26th year of the Republic of China, the rain always smelled of blood.
When the slit of Shen Yuhan's cheongsam swept across the moss of Shen Mansion, he didn't notice the bloody jade button on the porch - it was the Gu family's token. It appeared in the arms box at the dock three days ago, like an ominous omen. As the Shen eldest daughter, she wore counterfeit pearl earrings and walked among military and political officials. The cigarette on her fingertips burned the word "opium" on the account book, and also burned the rim of the champagne glass handed to her by Gu Yanzhi.
This man who suddenly appeared in Shanghai always had a white jade bracelet hidden in his sleeves, and his smile was like a knife tempered with honey. He said, "Ms. Shen's cheongsam was missing a button," but turned around and mixed "traction machine lead" into his father's medicine bowl. He helped her intercept the spies from Nanjing, then turned around and burned the Shen family's cigarette and soil distribution map to the special commissioner.
When the old letter about the Gu family's murder case fell out of the "Nanhua Sutra", when Shen Yuhan found out that he was a chess piece raised by Shen Xiaochuan for revenge, when the jade buttons finally merged into one - this entanglement that started with a calculation had already become a dead end.
"Between you and me, only one can survive." On a rainy night, she pointed a gun at him, but she didn't know that the gun pointed at her sincerity that she had hidden for ten years.
Only when the jade is broken can we see the true heart; after the palace falls, we can know the way back. This feud across Shanghai-Nanjing Port will eventually bloom in a pool of blood.
