Modern engineer Su Chen wakes up to find himself transported into the body of a streetwise rogue with the exact same name. Right from the start, people tease him: "Su Chen, want a wife? Just say the word and we'll send one over." Before he can adjust to his miserable life in a shabby house and tattered clothes, he encounters a wealthy young woman fleeing for her life. In these chaotic times of war and displacement, everyone wants to hide, but somehow he cannot escape the turmoil. Using his engineering knowledge, he figures out how to repair the house, build defenses, and find food to survive. At the same time, he forces himself to wield a blade, draw a bow, and ride a horse to protect his family. From a streetwise rogue to a man who protects his loved ones amid chaos, he has only one conviction: his family must survive.
