- Description from novelbuddy

The Revered Master, Yu Yan, known as the number one in the cultivation world, waited for sixteen thousand years, and finally took in a disciple. He taught her carefully, and took care of her diligently. He watched her as she slowly grew stronger as she comprehended the laws, and just as she was about to soar into prominence… she died!

Chen Lun transmigrated to the year before the game’s public beta, becoming an NPC in the game world. Thus, a new version was born... Steam punk, Mysterious Objects, Church, Shelter, the pathways of the Sequences of the Seven True Gods... He placed his black top hat on his head, standing atop the ruins. Behind him stood the villain bosses from former game versions, the silent Nun Floey, Bloody Painter Noah, Swordsman Antonio, the delusional clown Alec... Chen Lun said, “Players grind monsters, I grind players, it makes perfect sense...” ... Also known as “How to Rationally Use Players as a Sustainable Resource,” “These Bosses Are Really Strong But They Are All My Underlings,” “No Way! So I Can Be A Deity, Too?!”
