Yun Yichu is the eldest grandson of the Yun family, a talented scholar who has achieved the highest honors in the imperial examinations, including first place in both the autumn and palace sessions. He first appears as a pale-faced young man in mourning clothes, carrying an oil lamp and seeking the Artifact Spirit Pawnshop. Desperate to resolve the conflict ignited by the Six-Character Copper Coin, he contracts Chang Ming, giving her ten years of his lifespan. Raised strictly by his grandfather Yun Ruosheng, he bears the weight of family expectations and manages the household after the patriarch's sudden death. He is earnest, respectful, and deeply loyal to his family, often putting their needs above his own. He suffers a head wound during a confrontation with his uncle Yun Rong but remains steadfast. His love for his grandfather is shown through precious childhood memories and the jade cicada he carries. He is determined to restore harmony to the Yun family, even at the cost of his own future.
