The story takes place when the Qin Empire has just unified the six kingdoms. The protagonist Yang Li comes from a central farming family in Guanzhong. His father is an experienced old craftsman who has made weapons and armor for the army. Yang Li was not a born rebel, but an ordinary person who instinctively supported order and longed to settle down within the imperial system. He inherited his father's craftsmanship from an early age, and was drafted because of his skills. He was forced to flee and join the rebel army because he missed the deadline while being escorted to the corvee. He joined the rebel army. He relied on his craftsmanship and organizational skills to rise and fall in the rebel army. He successively served Chen Sheng, Xiang Yu, Liu Bang and other different forces, but he could never find his true belonging. After the world was settled, he refused to serve the new dynasty, and with his skills and heart filled with vicissitudes of life, he completely returned to the ordinary.
