Oh my! I’ve Transmigrated Into a Mighty Super-strong Fat Bandit!

Tian Mi, a twenty-six-year-old modern woman and PhD in traditional Chinese medicine, wakes up in the body of an eighteen-year-old fat girl in the Heaven Collapse Dynasty. The era is plagued by a severe drought, famine, and political chaos following the old emperor's death. Her new father, Tian Dabiao, is a strong but simple-minded bodyguard from the Fenwei Escort Agency. After the family’s supplies run low, they join a group that raids a bandit hideout, inadvertently capturing a handsome prisoner named Bai Mucheng. Tian Mi’s father declares her the prisoner’s wife, and in the ensuing chaos, Tian Mi takes advantage of the drugged Bai Mucheng, leading to a humiliating encounter for him.

Realizing the danger of their situation, Tian Mi leads her father’s group, along with several allied families, on a perilous journey to Xingrong County. She possesses a spatial dimension that allows her to store vast amounts of modern supplies, including food, water, and medical equipment. The space contains a spiritual well whose water accelerates healing and strengthens the body, as well as a river that can be used to revitalize the parched land. Tian Mi uses these resources to sustain her group, secretly providing them with better nutrition and water while maintaining a low profile. She also begins to lose weight and improve her martial skills, adapting to the harsh realities of the collapsing dynasty.

During their escape, the group encounters various threats, including corrupt county officials who rob refugees. Tian Mi witnesses the brutal murder of the County Magistrate and his family by the Head Constable, who turns bandit after his master falls from power. The Head Constable’s men also assault and kill several captured women, including Cheng Yuhuan, a relative of the original Tian Mi’s tormentors. Driven by a need for survival and justice, Tian Mi stealthily infiltrates the constables' camp at night. Using surgical knives from her space, she assassinates the entire group, securing their weapons, horses, and a significant amount of silver and treasure, which she stores in her dimension.

Tian Mi reunites with her maternal family, the Xu family, who have also fled to Xingrong County. However, she learns that her grandfather has died from injuries sustained in the crowd, and the family is fractured by greed and conflict. Some relatives have stolen supplies and separated from the main group. Despite the tragedy, Tian Mi continues to use her spiritual water to help the starving refugees along the road, filling wells and providing aid, which gradually earns her a reputation as a benefactor. She navigates the complex family dynamics and the ongoing threat of bandits and corrupt officials, determined to protect her loved ones and survive the catastrophic era.

The story follows Tian Mi’s transformation from a modern woman unprepared for such a harsh world into a capable leader who uses her unique advantages to save lives and secure her family’s future. As she moves deeper into the disaster zone, she faces the moral complexities of survival, the brutality of human nature, and the political upheavals that threaten to destroy the dynasty. Her journey is marked by strategic decisions, combat encounters, and the gradual accumulation of resources and power, setting the stage for her rise in this turbulent new world.
