Penniless graduate Lu Chenyu inherits a luxury villa worth over a hundred million out of the blue, only to be saddled with millions in debt—and finds the estate is a notorious haunted house shunned by all. Pushed into a corner, she breaks through a spacetime portal into a primitive world full of spiritual energy, accompanied by an arrogant portal spirit. With the other world's spiritual delicacies, her scallion pancakes become an instant hit, and her private-kitchen wild harvests sell for astronomical prices, connecting her with business tycoons and traditional medicine masters. She trades modern supplies to help primitive tribes, receiving peerless medicinal herbs like lingzhi and dendrobium, and builds her own cultivation base. As she runs her business, aids welfare home orphans, tames tribes, and unlocks the spirit's lightning defense, she leverages the price difference between two worlds to reverse her fate, rising from a debt-ridden pauper to a top cross-realm billionaire.
