How the Heck Did I Get Reincarnated as the Big Villain?!

The main story is complete! Thank you all for sticking with me! Three deep bows! Mwah! Starting February 1, I’ll be updating this book (please add it to your favorites): "How Do I Deal with My Stomach Mysteriously Growing After a Nightmare?!" (also known as "Birth of a Demon"): He gave birth to his own top_(:з"∠)_ Coming soon, available to bookmark from my author page: "I Heard I’m a Tyrant [Book Transmigration]": What a liar! I don’t want to have a baby! QAQ This story is also known as "The Shadow Demon Beyond Redemption," "The Story I Had to Have with the Protagonist," and "The Protagonist Insists on Loving and Killing Me." Oh no! Was I cursed by readers into transmigrating into a book because I stopped updating?! Good heavens! Why did I kill the male lead’s sister as soon as I got here?! I’m going to be killed by the protagonist now, dead as a doornail! What do I do, what do I do?! System! _(:з"∠)_ I’m the author, can I change the plot? Please let me live, argh! Simply put, it’s the story of a lousy author who transmigrates into his own book as the big villain, raises the young protagonist to adulthood in hopes of staying alive, and manages to save his life but not his virginity. Wait, young man, shouldn’t you be falling in love with the heroine?! No, I want to love and kill you! The once-adorable boy has somehow turned into a twisted young man, and now he leans over him with a sinister smile! Content warning: Early on, because of an injury, the character has to attach his soul to another person, so Shangguan Wuchen spends some time in a woman’s body. If you can’t accept that, please don’t force yourself to read it.
