The official title of this novel is: An Immortal Pets a Cat's Head; Neutering in Exchange for Immortality. Immortal top x cat demon bottom, a silly, sweet bedtime read.
Long ago, a ragged young boy gazed up at the White Jade Capital in the sky and swore, "One day, I'll tear apart the immortals' heavens."
A scrawny black cat beside him dug earthworms out of the dirt to eat.
Later, the boy became an immortal, destroyed the Immortal Way, and became its incarnation, the ruler of heaven and earth, invincible and unfaltering, the Fate Deity. He had no choice but to join forces with the immortals.
And that little coal-black cat also rose to immortality through connections, getting a job as a decoration in the Immortal Palace.
Rumors spread at once. Everyone said the Fate Deity had a bewitching cat lover in the mortal world, and now that lover had finally become immortal, the two of them spent every day together, oblivious to all of creation.
The Fate Deity could take it no longer. At last, at an immortal banquet, he called out, "Xuanyuan! Xuanyuan! Forget it... Coal Ball! Come out and take a few steps!"
Everyone saw a round, black eggplant trundle out on four toothpick-short legs.
The Fate Deity said, "Coal Ball, change back."
Everyone saw the chubby little cat turn into a three-hundred-jin, cat-eared fatty. He was still a eunuch.
Even after becoming immortal and witnessing the changing world, this was still one of the most eye-searing sights under heaven.
The Fate Deity nodded to himself. Surely now, no one would spread rumors that he and his eunuch cat had some kind of sixty-nine relationship.
But instead of stopping, the rumors about the Fate Deity on the immortal world's forum grew wilder by the day:
"The Great Fate Deity likes cat-eared otaku fatties."
"The Great Fate Deity likes pigs :)."
"The Great Fate Deity wears a XXXXXL red mandarin-duck bellyband."
The Fate Deity: "???????????? What the hell!"
The Fate Deity said nothing, merely coaxing his cat over and over: "Baby, how did you turn into a three-hundred-jin porker? Baby, I'm not saying you're not cute. You're adorable even at three hundred jin..."
The three-hundred-jin otaku, who couldn't understand human speech, struck an effortlessly graceful bridge pose. "?"
The Fate Deity: "... Ugh... Baby, Daddy just threw up. I'm not saying it's because of you. Daddy's just had too much to do lately and couldn't hold it in. It's not that Daddy finds you disgusting, Baby..."
The fatty rolled onto his back on the floor, made loose fists with both hands and pawed at the air, then let out an affected, drawn-out, "Meow. O_O"
The Fate Deity finally lost his composure. "Baby, lose weight! Baby, lose weight! Baby, lose weight!"
Much later, the piggy cat developed a proper human sense of beauty and changed his transformed appearance. But he still rolled around on the floor and drew out his voice to act cute for his master.
