The Nobleman in Another World

Content warning: The uke is trashy in the early chapters (emphasis added), but pampers the seme later. Younger seme, 1v1, happy ending. The general gist: A young uke carefully plots his way through a world of beastmen, eventually leading a hundred of them on a journey to find their way home. Wan Shu is in a plane crash and transmigrates to a world of beastmen, but thinks he has landed in Russia. He mistakes a handsome young beastman for a member of the famously tough Russian people, then flashes his gold card. "Be my bodyguard and escort me back to China. Name your price!" The young beastman is baffled: What is this? His heart gives a little flutter, his hand shakes, and the gold card snaps in two. Wan Shu: Damn it, my premium VIP card... Coming soon: After Being Corrupted by the Demon King Yu Shengyan was born unlucky. When he was still a baby, a demonic dragon used him as a record board for "I was here" and infused him with demonic energy, leaving him unable to cultivate for the rest of his life. Since Yu Shengyan could fall to demonic corruption at any moment, he couldn't do anything at all. He couldn't use magic or fly, and even hopping around a few times left him wheezing like he had asthma. Still, he was an optimist by nature and figured he could at least go down to the mortal world. So he went down to find his long-lost older sister. But traveling alone was a little scary. After all, he was a weak little demon, so along the way he latched onto a handsome guy who looked like he could really fight. The rabbit demon said warmly, "Hey, big guy, are you going to the human world?" The demon dragon replied with interest, "...Sure." Theme:
