I, the Core of the Abyss

Lin Mo never thought that the basement where he couldn't afford the rent would turn into his own - a breathing and growing underground city. Daily points can tap iron ore veins, kill adventurers to earn gold coins, and if you have enough magic power, you can add a second and third layer... It sounds like a fun game, but when the adventurers from the Glen Kingdom approached with long swords, the dwarves from the underground kingdom dug through the wall with pickaxes, and the strange shadow of the alien kingdom was about to move at the border, Lin Mo discovered: He's not playing a game, he's building a wall with his life. What's even more terrible is that he can see every move of the three kingdoms - the secret orders of the Royal Court of Grant, the mine distribution map of the dwarf clan, the ancient existence awakening in the alien swamp... When the human adventurer's torch illuminated the first level passage, and when the system prompted "The first intruder has entered," Lin Mo grasped the newly generated iron ore pickaxe: "I'm sorry, do you want to attack me? First, ask if this wall will allow you to attack." From the damp basement to the abyss maze spanning the Three Kingdoms, every brick he made was dipped in gold coins and cold sweat.
