Reborn back to 1969, Duan Qidong awakens a portable dimension and resolves to protect his wife Jiang Xue, his twin daughters, and his family relatives. Recognizing the callousness of the Lin family, he returns to Hekou Village, relying on dimension supplies and resourcefulness to head into the mountains for hunting, open up supply channels, enter the steel mill's procurement department, secure critical contracts, and defuse plot after plot and crisis after crisis. He helps his second older brother clear his name and arrange a marriage, secures a job position for his younger sister, and leads the villagers in increasing their income through fishing. Through trials and tribulations, Duan Qidong protects all his family members, and the family steadily marches forward toward a stable and prosperous new life.
