Lin Wanyun, an auditor at an accounting firm in her past life, spent eight years auditing fake accounts, training her piercing eyes. Transmigrating into the legitimate second daughter of the Lin family in the Dasheng Dynasty, she opens her eyes right on the day of the proxy marriage—the original owner was forced by her stepmother to marry the sickly Marquis, destined to be a widow in three months and buried with a single plain silver hairpin. Grasping all the memories of the original owner, she drops modern buzzwords to brush off the Zhuangzi slang, and from then on, the Marquis's estate gains a social-butterfly matriarch holding an abacus and flipping tables. Xie Heng, the Marquis of Yongchang, has been a Best Actor in the sick-acting category for seven years. Until that conciliation-bride wife enters the door, flipping the concubine's accounts on the first day, taking her stepson to hustle money on the second day, and on the third day... smashing straight into his heart while holding a door-prop pole.
