Bai Mimi is a small cat raised by the Jiuyou Emperor of the Celestial Court for five hundred years. Her daily routine consists of eating dried fish and causing trouble. Until one day, she accidentally eats a failed elixir of Taishang Laojun, transforms into an exquisite beauty, pounces on the desires-cleared and desires-free Emperor of tens of thousands of years, and conveniently gets pregnant with a dragon seed. To avoid being turned into a cat-hair duster, she plays dumb, frantically shifts blame, and flees overnight with a ball in her belly, only to be caught red-handed by the Emperor while stuck in a dog hole. Even more absurdly, the Demon Lord breaks his seal, and the Emperor uses his body to form an array with his life hanging by a thread. With her belly out, she charges into the Myriad Demon Abyss, using a cat-style confession to stubbornly shout her husband back from the gates of hell. Later, the iceberg Emperor drapes a phoenix robe over her, promising her, "Between heaven and earth, you are supreme."
