After I Transmigrated into a Book, the Demon Lord and I Shared a Body

(Dashing, flirtatious, and self-proclaimed devoted Demon Lord gong X fresh-faced, chatty shou) Feng Weijiang: I can't really stand people who talk too much. Gu Jingyan: What a coincidence. Talking is the only thing I'm good at. Gu Jingyan transmigrated into a book, specifically an immortal-and-demon novel. The absurd part was that he had never read it. Even more absurdly, he'd watched a heavily altered TV adaptation, but only the beginning. So Gu Jingyan had to charge ahead completely in the dark. You ask about the original plot? Sorry, I haven't read it. No idea. The plot's long gone anyway. And that's not all. Less than fifteen minutes after Gu Jingyan transmigrated, he discovered that his original Demon Lord body was still alive!!!! Gu Jingyan: “Wasn't the protagonist who transmigrates into a book supposed to kick the bucket?” How is he still alive??? Feng Weijiang: “Do you take me for one of those useless fools???” Gu Jingyan: “Sorry, I was wrong.” When the Demon Lord agreed to give him a new body, Gu Jingyan was so grateful he could have hugged him and wept. But after all his efforts to get himself a body of his own, he discovered... “Didn't you promise to reshape my body? Why am I a sable?!” Feng Weijiang scooped him up and stroked his fur. “Don't worry, it's a sable with a very beautiful coat.” And finally, when Gu Jingyan had completely turned into a ghost, he was utterly dumbfounded. Grabbing Feng Weijiang by the ear, he shouted, “Didn't you promise to give me a new body!!!!” Feng Weijiang smiled wickedly. “Easy, easy.” Only then did Gu Jingyan realize that this whole business about a new body was nothing but this guy's twisted sense of fun!!!!
