Doomsday scientific research tycoon Jiang Li time-traveled, only to discover it was her past life. The original owner was a lazy wife in the 1960s, facing harassment from her second sister-in-law, with two skinny and timid sons. Armed with a super-brain system and storage space from her past life, along with a treasured jade pendant left by her maternal grandmother, she changes her past slacker ways, settles the allowances, reclaims chickens and private plots with the second branch, and treats Shitou and Mutou well with new clothes and milk powder. She plans to dig a well in the courtyard to improve their lives, make up to the children wholeheartedly, and stop her step-sister Jiang Yan from stealing her opportunities and stepping on her family to rise, properly managing her days to protect her two sons.
