The Ratfolk Rule the Dungeon

Twitch, a Clash of Clans fan, accidentally transmigrates into a perilous dungeon and becomes a lowly rat that even goblins can casually crush underfoot. With monsters all around him and adventurers hunting them down, Twitch thinks he won’t survive past the third episode. Then he awakens the Tribal Chief System, which lets him earn Elixir and Gold by dismantling supplies, as well as create troops and build up his territory. 【Wizard Rats: These rats command all kinds of spells, casting a terrifying shadow over the battlefield as they destroy every target on land and in the air.】 【Spring Trap: There was once a marvelous spring trap right in front of me. I didn’t see it, and then... well, there was no then.】 Reading the System’s descriptions, Twitch follows his inner rat, staying holed up in his territory: build high walls, stockpile food, and don’t claim the throne too soon! Upgrade the nursery and unlock rat troops: From basic Builder Rats to Barbarian Rats, Bomber Riders, Balloon Rats, and Rat Witches who summon the undead, even legendary rat heroes emerge, and the rat horde never stops growing! Upgrade defensive buildings and seize control of the ground and sky: Archer Towers, Cannons, X-Bows, and Inferno Towers rise from the ground. Traps cover the land, walls form an unbroken line, and the dilapidated rat nest gradually becomes an impregnable fortress that even dragons can’t breach! Years later, walls and traps cover the entire dungeon, while Twitch’s rat minions carry out his will across the land. Twitch sat alone on his throne and murmured with a sigh: “How’d little old me end up becoming the Demon King?” 【A wild mash-up setting】+【Nonhuman protagonist】+【Some Clash of Clans elements】+【Infrastructure and mass troop production】
