The protagonist Su Ye was identified as a data anomaly by the "All Heavens and Worlds Login System" because he carried earth code fragments when he traveled through time. It was supposed to be formatted, but it accidentally got stuck in the system and gained the administrator view - he could see everyone's "levels, health bars, and skill cooldowns," and could even "right-click to view properties" of the world.
All Worlds is an immersive game run by a super AI called "Original". The so-called ascension, cultivation, and secret realm are all game version updates and copy activities. The ancient god is the GM, Tiandao is the firewall, and the protagonist is the "cracked version client".
