When Lin Wanqing, a bamboo craft girl from Qinglan Village, went into the mountains to select bamboo, she accidentally rescued Gu Chenchuan, the president of the Gu Group, who had fallen into a deep pit. With ten million and a piece of agreement, Gu Chenchuan brought her back to the Gu mansion to assist in finding the group's internal spy. From banquet seating, antique jade pendants to supply chains and data leaks, Lin Wanqing used her skills in recognizing bamboo, identifying moisture, and observing mountain trail traces to see through traps time and time again; Gu Chenchuan gradually learned to respect her choices from "buying her time". As old lover Chen Xiao, socialite Tang Wanning, and Gu Chengyue took turns creating public opinion and crises, Lin Wanqing never relied on men to win for her, and finally uncovered the truth of the internal spy together with Gu Chenchuan, firmly guarding her workshop and life.
