Doomsday powerhouse Tang Tian transmigrates into an ancient, bullied peasant girl whose family is in a miserable plight, with relatives suffering consecutive disasters. Relying on the spiritual spring and supplies from her portable space, she skillfully makes specialty tofu and leads her family in breaking away from the troublesome clan. She faces her father who abandoned the family, decisively draws a clear line, and makes an independent living. Afterward, she opens workshops and restaurants, takes the lead in establishing a cooperative, cures her eldest brother's illness, and leads the fellow villagers toward prosperity. Faced with continuous malicious framing and foreign enemies invading, she calmly responds and rallies everyone, ultimately growing into the Lord of Tang Family Fortress who protects the local people.
