A 21st-century military doctor Mara Linton, who possesses a Personal Storage Dimension, accidentally travels back to ancient times and becomes the daughter of a village butcher, whose original body weighs 200 pounds! Fortunately, she retains her immense strength, and her Personal Storage Dimension has also traveled through time with her. Immediately after time travel, she is informed that she is the Long-lost Legitimate Daughter of the Yongning Marquis Manor. After moving into the manor, she is ostracized and looked down upon by the entire household, mocked as a savage fat woman. Mara Linton refuses to tolerate the mistreatment, she exposes and defeats scheming fake ladies, confronts her biased and snobbish elder brothers, rises steadily with overwhelming strength, and finally makes a stunning, showstopping appearance at a grand feast, proving a powerful truth: in the face of absolute strength, all schemes are nothing but paper tigers.
