The Yin-Yang Courier Earns a Million an Hour

[Fake heiress and real heiress + supernatural powers + revenge on scumbags + not scary~~] Absent-minded, adorable college student × sharp-witted, scheming private detective Song Wanji had always had an easy life, until she learned on her eighteenth birthday that she was a fake heiress. Her parents had plotted against her, tricking her into going to the hospital and forcing her to donate bone marrow to their real daughter. In a single night, she'd lost her family, all her money, and ended up living on the streets. Just when she was about to despair, she accidentally activated the Yin-Yang Delivery System and became a proud courier traveling between the worlds of the living and the dead. Before she knew it, everyone revered her as a “true master,” and she was earning a million an hour. At first... Her heartless adoptive parents force her to donate bone marrow? She smiles on the outside, curses them under her breath, and makes sure they spend the rest of their lives behind bars. Little ghosts pick on the weak and make a game of scaring Song Wanji? She brings out her ghost-slaying talismans and turns them all to dust! Orthodox mystic sects look down on her and bully her? She cries pitifully to their faces, then sends them one by one to have tea with the King of Hell! Later on... Her scumbag parents: Wanji, please make these evil ghosts go away! Little ghosts: Master, let me be your sidekick! Mystic sects: Ancestor, please accept this disciple's humble bow! Song Wanji not only found her birth parents, but also helped her family weather a crisis. She became a genuine heiress in every sense and went straight to the top. Before long, a gentle and charismatic idol, a sunny young master from a wealthy family, a handsome business elite, a soldier with an eight-pack... all declared that Song Wanji was the only woman they'd ever marry. Song Wanji: Tsk, tsk, which one should I choose? If only I could have one a day. Chen Zui: ? Do you have the guts to say that again? That night, Song Wanji said nothing, her gaze simply going unfocused.
