Saving All of Humanity Today Too [Reborn]

An early work. Not very good, and the writing is pretty weird. After the merman emperor unifies the world, he says, "Humans have annoyed me for ages. Let's wipe them all out." Pei Yan, a half-merman, is in an awkward position. So after being reborn, he plans to slap the faces of that despicable couple first, then run away as soon as he can. But before he can run, he meets the future merman emperor...??? Pei Yan thinks that, for the sake of humanity's future and world peace, they should use love to change him. But His Majesty says that using your body to change me would be more reliable. Also known as: "Using My Body (crossed out) Love to Change a Murderous Madman (????)" Obsessive merman top x a pretty handsome bottom Pei Yan: I'm Pei Yan. My wish... is world peace. His Majesty: Sure, darling. Get on top. Things to know before reading: 1. The bottom had a pretty miserable past life, so he has a dark side. 2. He's not a naive sweetheart. 3. Sex first, love later. 4. Wish fulfillment. 5. Anyone who insists on both leads being sexually pure, don't click. Thanks. Let's leave each other alone and be grateful for this world. Cover image found online.
