Skill Up for One Dollar, Call Me SSS Law God

After transmigrating into a profession awakening world, Xiao Fan awakens as a low-level mage, only to be dumped by his girlfriend Liu Ruyan and ostracized by his teammates. Originally, his system required ten thousand dollars to upgrade a skill, but after accidentally deleting a character, the cost drops to just one dollar per level. Armed with this pay-to-win system, Xiao Fan solo-challenges the high-difficulty Nine-Layer Demon Tower, crushing every obstacle and slapping faces of his former teammates who looked down on him. After venturing out of the city, he falls victim to an ambush by members of the Evil Spirit Destruction Society. Relying on life-saving gear reinforced by his pay system, he escapes death and counterattacks, killing his enemies. He then single-handedly clears the mutated ant nest dungeon, collects the legendary set, reaches the level threshold for class change, and heads to the Class Change Temple, where a new battle begins.
