Chen Lun traveled to the year before the game’s public beta and became an NPC in the game world.

And so, a new version was born…

Steampunk, spooky things, churches, shelters, the sequence paths of the seven righteous gods…

He put on his black top hat and stood on top of the ruins.

Standing behind him are the villain bosses of various versions in the previous life, the dead nun Floyd, the bloody painter Noah, the sword fighter Antonio, the delusional clown Alex…

Chen Lun: “Player spawns monsters, I spawn players, this is in the Taihe River…”

…

Also known as “Rational Use of This Sustainable Resource Named Players”, “These BOSS are really strong but they are all my younger brothers”, “No way! So I can also become a god? ! “
