Carpenter Gu Chengjun accidentally opened the ancestral jade box and activated the "Baigong Game System". He had to complete ancient life tasks (making tools, building houses, and solving puzzles) to unlock rewards. He started from a street woodworking stall and repeatedly solved problems with his system-integrated game character skills (Lu Ban Shu, Mechanism Technique, Treasure Appraisal Eye), and gradually became famous. During the process, he met Su Qinghuan, the daughter of a reclusive pharmacist. From misunderstanding to acquaintance, they worked together to resolve the workshop crisis, sect disputes, and royal secrets, and finally revealed that the jade box was an artifact left by the saints of ancient craftsmen.
