Top-tier game designer Lin Feng transmigrates to a fantasy world called the Firmament Realm, bringing the entire game's development backend with him. He discovers that the world's cultivation system and manuals share the same source code as the game he designed. While others painstakingly cultivate the Laws, he debugs bugs; while the mighty summon the power of heaven and earth, he writes the rules. From being dismissed as a good-for-nothing to becoming the “administrator” behind the world, he uses modern thinking and code-level privileges to rebuild this brutal otherworld, riddled with bugs.
