In the Corpse River, all the water that touched Captain Rat would turn into part of it. It was more than 60 feet long. White saintly light shone from its left; black evil light shone from its right. The two forces, yin and yang, flowed around it.
When it realized that the river couldn't hurt it, it grew cocky. "The demon rats fed on the most toxic foods in the world in the ancient times," it said, scoffing. "Not even the Styx can make me surrender, let alone the Corpse River."
Seeing the demon rat like that, Blackie was annoyed. It ran to the side of the river, grabbed the demon rat's tail, dragged it back, and beat it up.
The demon rat kept begging for mercy and finally, Blackie stopped. After all, it still had to carry Mu Lingxi and Blackie across Corpse River and into the netherworld.
In the netherworld, the eerie Qi in the air thickened. Even the temperature dropped. There were blood-red ice bits mixed in the dirt.
