After the unification of the Daqi Dynasty, the descendants of the royal families and core nobles of each dynasty were moved to Gui'an City for "captivity" and control. The nobles inside the wall guarded the glory of the previous dynasty and fought among themselves, while the civilians outside the wall struggled to survive under class barriers. Gongmei was admitted to a carpenter school with her superb carpentry skills, and she and Chen Mo gradually became close friends and lovers from rivals.
The tragedy in Yongningbao broke the peace. The young girl next door, Xixi, became a powerful experiment and died tragically. The desperate situation of having no way to defend her rights made Gongmei completely awaken. She is no longer satisfied with relying on skills and is determined to break Gui'an City's strict skills monopoly - core skills are produced exclusively by designated places and people, and anyone who secretly produces and transmits them will be imprisoned. Gongmei vowed to make craftsmanship beneficial to all living beings. Faced with the suppression of the Wen family and other old nobles, and the secret checks and balances of Pei Yan, the envoy of the Great Qi, she and Chen Mo survived in the cracks, quietly improving farm tools, opening civilian workshops, and using wisdom to circumvent the ban.
In the process, they met Xiao Che, Wen Wan, Wei Feng and other righteous young aristocrats, and formed a group. In the whirlpool of internal strife between the bereaved nobles and the confrontation between old and new forces, they used craftsmanship as a blade and friendship as a shield to fight against the unfair system and power. From apprentices in a crafts school to top craftsmen, from obscurity to shaking up the structure of Gui'an City, Gongmei and Chen Mo not only achieved personal growth, but also worked together to build a bridge between common people and awakened nobles to change their destiny.
When the opportunity to study in Daqi came, the two embarked on a new journey with the hope of returning to An City. A revolution related to the inheritance of skills and class equality was quietly beginning. This is a legend that breaks through shackles with ingenuity and withstands wind and rain with friendship. It writes a touching story of common people awakening in desperate situations and nobles reflecting under the shackles.
