Su Mu was originally an ordinary person suffering from a serious illness. By chance, she encountered System 0138. The system allowed her to enter different dungeons. As long as she could reach the SSS level, her life would be renewed. She and the system were the only friends who knew each other during the day after day of dungeon clearance. She named the system Chuxue because it was the first heavy snowfall that year when they met. When they parted, the sky was filled with snow.
Intention: We in different time and space will eventually meet
