While many stories feature protagonists transmigrating from Earth to another world, our Lin Yun does the opposite, traveling from a different realm to Earth. Yet, this isn't the most vexing part. What truly drives Lin Yun to madness is finding himself confined within a mental hospital. This novel is arguably one of the best urban stories, offering a perfect blend of emotion, passion, and adventure. Readers will encounter Lin Yun, a character deeply loving towards his significant other but utterly ruthless to his foes. He is a hidden genius who prefers not to flaunt his abilities. The narrative chronicles his quest for ultimate power and his fierce struggles to protect those he holds dear. A standout feature is the author's profound and natural depiction of romantic relationships. Unlike many other novels, the female characters are not mere decorative 'flower vases,' nor does the male lead promiscuously gather every beautiful woman. This is an urban novel that online fiction enthusiasts should not miss.
