Stellar Slacker: I Thought This Was an Idle Game!

An ultra-chill modern gamer reincarnates onto the most dilapidated floating island of an elite magic cultivation academy. Armed with an ancient enchanted slate he mistakes for a mobile idle game, Felix Vance takes 14-hour naps to accumulate AFK rewards and compresses a literal G-type burning sun into his chest to optimize his offline idle generation. While he complains about bad gacha rates and unskippable dialogue, the world descends into Lovecraftian reverence, convinced he is an ancient slumbering cosmic sovereign.
