I’m a Reincarnated Dragon, but I Just Want to Be a Layabout in Another World

I transmigrated into a half-blood white dragon. My birth mother is a pure-black she-dragon, and she looks at me as if I’m a disgrace to dragonkind. No matter. I have a System: daily sign-ins, and points to grow stronger. I’d planned to keep a low profile, cling to my mother, and coast through life. Then I sneezed and spat out a live sea fish. My mother pried my mouth open, took a look, and coldly muttered, “Just like that wretched dragon.” Me: “?” Later, I spat out a sea turtle, a weapon, and even a voice that could speak human language. At last, my mother lost her composure. “What exactly are you?” I blinked at her. “Your son, of course.” “Mom, I’m hungry.”
