"Heh heh, King Sun-Swallowing, I came here today to congratulate you."
Feng Xu held his right hand across his chest and saluted the Demon King respectfully.
A flicker of surprise crossed Sun-Swallowing's eyes.
"What do I have to celebrate?"
"I pursued the humans for hundreds of miles, only to be stopped by one of them. After defeating him, I learned a method for refining baleful qi. It occurred to me that one of the Dharma Treasures you obtained a few days ago had something to do with baleful qi."
"If you learn this method, you'll surely be able to control that Dharma Treasure. You might even advance your cultivation another step."
Thinking of the Fiendish Weapon he had never managed to refine, Sun-Swallowing felt a spark of interest and invited Feng Xu into his Cave Abode.
"Brother, I do indeed have a Dharma Treasure I've been unable to refine. But why have you suddenly come here today offering to help me?"
No one helped another member of the Demon Race for no reason. Every favor and obligation revolved around profit.
"I wouldn't dare deceive you, Your Majesty. I found human flesh quite delicious. Rather than leave empty-handed, I thought I might take some humans back to savor at my leisure. Besides, after witnessing your mighty bearing, I felt a great yearning to serve you. I wish to pledge myself to you, so I'll have someone backing me on this land in the future, won't I?"
Feng Xu kept flattering the Sun-Swallowing Demon King, all but praising him to the heavens.
"I believe you're a demon blessed with great fortune. With the right opportunity, you might one day be every bit the equal of those great demons in the Heavenly Palace."
"Brother Zhufeng, mind your words."
"What's there to worry about?
