The Little Girl Is Actually a Full-Level Boss

"Little brother, wuwuwu——don't leave!" The little girl hugged the boy's legs tightly, her tears wet his trousers, and her cries were so choked that she could hardly breathe. The boy, who was five years older than her, gently rubbed the top of her hair with his fingertips. His voice was gentle but undeniable firm: "Good boy, when you become powerful enough and can stand on your own, I will come back to you." The image of him turning away has become the girl's only obsession for many years. No one knew that that crying little girl would grow up to become a walking legend—— She is the top hacker "zero", she is the world's number one killer "I", she is the top international designer "Yin", she is the popular script-making machine "Y", and she is also the president of the alliance that commands the global medical community! When she stands in front of him in all her glory, will he still recognize that this woman who made the world tremble is the little one who chased him and cried back then?
