Why Can't a Kitty Become the Demon Lord?!

“The world can’t be without cats!” Tu Miao declared. “The world can’t be without dogs!” Wang Wang declared. They both turned to look at Yan Yuzhi. Yan Yuzhi: ... Who would have thought that the Demon Venerable and the chief steward of the Demon Palace were actually demons in name only, and were really yao? So the Demon Venerable, whose bloodline was impure, was sent to the human realm to undergo trials. Tu Miao wasn’t having it! Why couldn’t a cat be the Demon Venerable? She was much better than the last Demon Venerable, who kept insisting he wanted to go to the cultivation world and become a shining example of righteousness! With a spy (Yan Yuzhi) and a dog in tow, she roamed the world, determined to gather powerful vengeful spirits from the human realm and return to the demon realm in triumph. The first vengeful spirit she encountered was the false young master of Changliu Manor. At sixteen, he learned he was merely the cuckoo who had taken over another bird’s nest. He exhausted himself and gave up everything to make it up to the true young master, because everyone said he owed the other boy the sixteen precious years of his life. But when he was dragged into the most sinister mass grave, all he had to do was reach out to touch a bleached white corpse. Before him, a malicious ghost drooled with greed... Was half his flesh and blood still not enough to repay the kindness of raising him for sixteen years? He sneered, finally seeing how little his own life was worth. So be it. Let his boundless resentment turn him into a vengeful spirit, doomed never to be reborn, as he watched Changliu Manor slowly fall into ruin. When he met Tu Miao, he said, “I’ll give you my soul. Help me take back what’s mine.” Once, I was the one who owed you. Now you’re the ones who owe me. May you all die horrible deaths! (I can’t write any more vengeful spirits, waaah TAT)
