Famous Summoned Beasts Through the Ages

Lu Xiuyuan: A criminal investigation officer and an absolute atheist. His favorite saying is, "The truth will never be buried." Unfortunately, he made friends with the wrong person. Since childhood, he had been inseparable from Zhang Yuhao, who was destined to become an exorcist. In the end, he was dragged into the four-dimensional world of ghosts, gods, and monsters, where he met all kinds of strange supernatural beings and was spirited away by the black dragon Hei Ao (pronounced He, fourth tone). Hei Ao: A divine summon who had been sealed for more than five hundred years, he had lived on in tales, novels, and ghost stories. At last, one day, the seal was broken. He thought he'd encountered someone who could give him a title, but gradually realized it was all part of an unspeakable plot. Irresponsible blurb: Zhang Yuhao (female): I think aside from clarifying my gender, there's not much else to add? Azure Dragon (Qing Cang): You have me, too~~ Add me to the notes as well. White Tiger (Bai Mo): I don't know these people. They're so embarrassing. Vermilion Bird (Zhu Qitong): Tiger, bring the two turtles. We're leaving. Black Tortoise (Wu Xuan): zzz… All the monsters: What kind of weirdos are these?! Author: Actually, Yuhao, you're the only heroine in this story~~ (Even though this is a BL novel~)
