Shen Yunwan married into the Xiao family for four months and knelt in the snow for three hours. She was the daughter of a guilty minister and was taken as a concubine by the Xiao family for the Feng Shui painting left by her father. The painting contained the secret of the dragon veins of the Xiao family's ancestral tomb. But she didn't know where the painting was. She only knew that whenever Xiao Yan came close, memories that did not belong to her appeared in her mind: heavy snow, a short knife with the word "Yan" engraved on it, the sharp pain of being penetrated in the chest, and someone calling her "A Wan" heartbreakingly. Xiao Yan was weak and coughed up blood, and was left in a remote courtyard. However, Shen Yunwan discovered that the old scar from his tiger's mouth was at the same location as the person who killed her in the dream.
She began to investigate and found out the truth about the three-hundred-year-old chess game - all the daughters of the Shen family were "baits" thrown into the well to catch Xiao's immortal soul. It took her mother twelve years to climb out of the well, her grandmother to make the second hook, and her father spent sixteen years to grind the stone, carve names, and push the door open, just to let his daughter out of this game of chess. And she was the last bait and the last hook.
"Use hook as bait, use bait as hook." Her father only made one wrong word in her life, and hid the way to break the situation in her name. She will finish the road paved by her mother, read the names of three hundred Shen's daughters, and take back the three hundred years of bait thread one by one. And Xiao Yan, the person who killed her in the previous life, has guarded the door for her for three hundred years in this life. The scars on his hands, the blood he coughed up, and the rice paper he wrote "A Wan" all over were the same answer - this time, he would not let her go alone again.
"Where the bait is gone, the shore will open up. Mom is waiting for you on the shore."
