Infinity Mage [Isekai LitRPG]

Arthur figured life couldn’t get much worse. Then the world ended. All he wanted was enough money to take care of his little sister, and he finally landed a job where he could do just that. The problem? All of humanity was abducted on his way to work. Worse? They’re forced into an alien death game with one solution—kill the final boss, or die trying. They’ve got 600 days to get the job done before the planet explodes. But in this system ruled world where every second counts, Arthur’s got an ace up his sleeve. A unique gift that lets him access infinite mana. With it, he’s got a chance, but will he live long enough to use it? Because in the 198th Omni Games, it’s kill or be killed. But Arthur's sister is missing, and he's willing to do whatever it takes to find her, even if that means being a player in their game.  Though truth be told, he never was good at playing by the rules.
