Unfortunately, no one had ever seen him, nor did anyone know his age or gender. He was shrouded in mystery, not affiliated with any organization, and no one knew how he had appeared. All that was known was that about four years ago, he had suddenly burst onto the scene and had successively pulled off several major cases, each one rated as a 3S level mission by the global Assassin Alliance!
Liu Yan was a man who had no idols, but if he had to choose one, that person would be this doctor!
From the first time he heard about the doctor's deeds and saw the sincere admiration in his instructor's eyes, he had firmly remembered the doctor's name!
But he hadn't expected to have an encounter with the doctor so unexpectedly!
However, he knew that the instructor would absolutely not deceive him or joke with him. From the doctor's tone of voice just now, and his words, it was clear that they had known each other before!
The doctor was so young!
And he was even a student at Z University!
