Rong Yu, a legendary mathematician from the early days of the People's Republic of China, died in a car accident saving her son. When she woke up again, she found herself as the “easy target” great-grandma of the modern Ji family—relatives dismissed her as a burden, her granddaughter-in-law stepped on her to fight for family assets, and even her great-grandson was bullied at school! But who could have guessed that inside this “confused old lady” lived the genius mind that once calculated missile trajectories with just a pen? When greedy relatives tried to seize the Ji family's property and a naughty kid bullied her precious great-grandson, Rong Yu used game theory to expose scams, solved math problems to subdue rude neighbors, and even used a “logic trap” to stop her great-granddaughter's school bullying—turns out the most untouchable one is always the “old treasure” with hidden sharpness!
