Everyone Builds a Castle: From the Start, My Only Castle Is Twin Cities

A billion living beings arrive and become castle lords, building their own territories and fighting against the myriad races.

The legendary dragons, behemoths, vampires, werewolves, griffins, ogres, and elves will all become units for the castle lords, helping them repel foreign enemies and seize resources!

On this path of competition among the myriad races, you must either conquer and become the strongest, winning eternal life!

Or submit, becoming a powerful one's slave, losing yourself and struggling to survive!

Or... perish!

"Holy crap, a lord-rank Undead unit! No, I've got to go brag about it in the chat hall!"

Qin Ge stared at the angel and demon before him, baffled.

"Why don't my units have ranks?"
