The top assassin “Zero” is reborn in the body of Su Wan, a timid true heiress. She returns with multiple secret identities as a hacker, medical and poison expert, and master of ancient martial arts. Rising from Class F to become the national champion, she gradually uncovers the baby-swapping conspiracy, crushes the fake heiress, topples the Abyss organization, and builds a business empire. And the Dragon Group adviser, the only person who has seen through all her secret identities, is waiting for her to confess in person: “No matter how many identities you have, I’ll be here.”
