setting descriptions from novels

Lee Fei is a normal 30-year-old man who has a good job as a librarian at the National University in China. He is an avid reader and has always read everything, including BL and GL, even though he declares himself 100% straight. He died just like that. There was no truck. There was no car accident. No deadly disease. Lee Fei reincarnated and transmigrated to the world of the book he had read days before he died. Unfortunately, a BL Dark Book. The worst, he transmigrated as an insignificant side character! Lee Fei became Emery Darcy, who is the third child of a powerful duke. Your life should be full of wealth and happiness, right? Unfortunately, Emery Darcy followed the path of an exorcist! Yes, Emery Darcy is an Exorcist Bishop! To make the irony of his situation worse, this side character had a worse fate than the villain. What an injustice! As the knowledge of the plot of this world, Lee Fei intends to return to the home of his rich family and live a good life! So, what if he has divine powers and MANA from nature? He just wants a rich and peaceful life! Ehhhh? Is the MC making a honey trap for me? Is ML no longer a possessive demon, but a tsundere that is following me? Is the fallen archangel a shameless voyeur who spies on me even in the bath? A guardian knight who thinks I'm the reincarnation of the god of nature? Stay away from me, I just want a peaceful life! Does apocalypse come far? No matter, I'm rich enough to protect myself! Let's have a happy and rich life as a good nobleman should be. NOTE: 1. R 18 2.
