After dying unexpectedly, she was reborn as a ten-year-old little girl in an ancient farming family, with barely a few rooms in her house and even fewer acres of land, not to mention a household of the old, weak, sick, and disabled.Fortunately, the elders in the family were kind and honest, her brothers loving and good-natured, and the neighbors harmonious and friendly. For Yang Mengchen, who had suffered from her relatives' torment and endured all sorts of mockery and scolding since she was young, this was truly a blessing from heaven.To support the family she loved, she resolutely took on the heavy responsibility of providing for them. If she, a modern corporate CEO who had once dominated the business world, couldn't feed a family, then who could?Pharmaceutical recipes, building greenhouses, opening storefronts... Not only did her family start living a comfortable and prosperous life, but she also led the surrounding villages in creating a magnificent pastoral scene!With money and fame, as she grew up, Yang Mengchen decided it was time to choose a husband, and thus, young talents from around the world began to flock to her.Who knew a grim-faced god of death would be blocking the entrance to the Yang family's home?“You're too tall, you're too short, you're too fat, you're too skinny, you're too dark, you're too pale, you're uneducated, you're deceitful and sly... All eliminated!”In a moment, the entrance was empty, and Yang Mengchen was instantly furious, “Prince, you've driven everyone away. How am I supposed to choose a husband now?”“I would like to see who dares to marry you. I wouldn't mind sending him to the Underworld as a groom!”Yang Mengchen...A certain Prince counted his merits on his fingers: “I have power, prestige, and substance, no concubines, no secret love affairs, no gallivanting— I embody the standards of a husband's three obediences and four virtues... In short, only I, this unparalleled good man, am worthy of you!”The guards: Oh wise and valiant Prince, is it really good to be so lacking in your role as a husband?
