[Decisive to kill, not the Holy Mother, counterattack, system, overhead, universal job change] When everyone changes jobs, everyone is buried because of their talents, but I can upgrade my talents through the system. Faced with his mother's serious illness, Lin Yuan became a professional in high school, but he was the weakest. His mother's medication was expensive, but as a weakling, it was really out of reach for him. But if not done, the mother will die within three years. But just because of this, Lin Yuan died... But in the end, the miraculous resurrection accidentally awakened the system. He didn't expect that the system's rewards would make him stronger step by step, and finally stand at the pinnacle that he never expected.
