I Really Am Not The Lord of Demon Novel

Ling PingAn, proprietor of a humble bookstore, desires only a quiet, uneventful existence. Yet, his quiet life is disrupted by late-night visits from troubled adolescents. To maintain his business, Ling PingAn adopts a playful persona, passionately recommending his books. After much persuasion, customers finally agree to purchase, only to reveal they lack funds and offer seemingly divine artifacts as collateral. Resigned, Ling PingAn accepts. Unbeknownst to him, the books purchased undergo transformations, with titles like "Secrets of Cosplay" morphing into "Lower Abyss Research Report" and "Stellaris: Settings for Synth Ascension" becoming "Gospel for Synthetic Beings." To these customers, Ling PingAn is a terrifying sovereign of Diablos, a supreme being controlling all realms. He, however, vehemently denies these perceptions, insisting, "I’m not, I didn’t, don’t talk nonsense."
