[The cold and ruthless young master × the poisonous lady|Fated showdown|Double strength|The secret of the imperial mausoleum|The poison haunts the heart|Two-way redemption]
"Either follow me, or I burn half of the picture."
Tang Yu, the cold and ruthless young master of Duye City, has a strange flame mark on his heart and is riddled with cold poison. When he crushes her disguise mask, a transaction involves the two of them in a strange chess game.
"The contract of living together has been concluded. Even if I die, you won't be able to survive!" Once the poison is poisoned, life and death will be the same. Using the poison as a guide and the blood as a blade, Hibiscus worked step by step, but when she uncovered the truth, she was shocked to realize that the so-called treasure map was the curse of the Yuwen royal family that cut out the blood of the Mu family girls a hundred years ago! The burning birthmark on her wrist is the key to the blood sacrifice; and her most trusted sister has long been reduced to a heart-cutting knife. Sister Haitang's gray right eye, the gray and rotten flame pattern, the puppet threads surging underground in Watano City... All the conspiracy points to a blood sacrifice that spans a hundred years.
Live and die together, the fire will burn brightly. She fed the poison with blood and burned all the sinful debts of the imperial mausoleum; he cut off his heart and inherited half of the backlash. When Xuetang Tu was reduced to ashes in the flames, and the chains of fate were shattered, leaving only the peach blossoms in Taoyuan Valley blooming like snow.
"It's windy and snowy in Huangquan, I'll go with you."
"I feed the poison with blood and burn this dirty world to ashes; you broke the sword and swore to give me a long-lasting firework."
