KO One: Summoning the Myriad Worlds to Conquer the Ultimate Class

Li Fei unexpectedly transmigrated to the Ultimate World. An ordinary person in this world of supernatural powers was in for a truly miserable time, but he awakened a golden finger: his System lets him sign in once a day and receive a card. It could be a character card, a skill card, a cultivation technique card, an item card, or any other kind of card. Their rarity ranges from junk to precious. Watch how he uses the System to thrive in the Ultimate World and rise to the very top.
