Ma Ming nodded, and began to speak about Red Garment Ah Piao.
From Ma Ming's recounting, Little Taotie and Hua Jinyan learned that Red Garment Ah Piao was a vengeful spirit that had lingered in the mortal world for a thousand years.
Because she killed many, she became fiercer than an Evil Spirit after death, and ordinary Evil Spirits were afraid of her.
Vengeful spirits that stay in the mortal world for too long gradually blur their memories and become food for Evil Spirits. Ordinary Evil Spirits feared her, but the Ghost King did not and wanted to devour her.
She had Buddha's Light protecting her body, and the Ghost King that came to devour her instead got devoured by her.
Since then, over the thousand years, she had grown increasingly stronger, which was the fundamental reason why vengeful spirits were so powerful.
"Why does she have Buddha's Light on her?" Little Taotie asked, puzzled.
