Chen Mo, an orphan adopted by the Chen family, inherits his grandfather's exceptional woodworking skills. Before passing away, his grandfather entrusts him with the ancient and mysterious book, The Luban Book. But immediately after the funeral, Chen Mo is kicked out by his adoptive parents and adoptive older brother, Chen Feng, who leave him with nothing but a dilapidated old house. Using the secrets of The Luban Book, Chen Mo unlocks the hidden mechanisms inside the house and discovers priceless thousand-year-old golden-thread nanmu wood and a rare wood spirit fungus. He also becomes acquainted with Gu Ting, a highly respected authority in the antiques and collectibles world. Consumed by jealousy, Chen Feng repeatedly joins forces with local gangsters to suppress Chen Mo, setting fires and framing him. But Chen Mo carefully plans his moves, using his extraordinary craftsmanship and sharp mind to turn the tables. Ultimately, he sends Chen Feng to prison, establishes Donghai City's largest woodworking workshop, leads his entire village to prosperity, and becomes a legendary master of mortise-and-tenon craftsmanship.
