Wuxia: The Super Slave Master

What? Zhang Wuji abandoned you on your wedding night to go find Zhao Min? No worries, I can help you get revenge! As long as you, Zhou Zhiruo, drink this drop of the Demon King's blood, you can go and seek revenge on Zhao Min!
Murong Fu is only thinking about restoring his kingdom and doesn't care about your feelings? It's alright, I can make him stop thinking about restoring his kingdom! As long as you, Wang Yuyan, drink this drop of the Demon King's blood, you can control your cousin!
The world says you're a ruthless female demon who kills without hesitation? You want to see Lu Zhanyuan? OK, I can let you see Lu Zhanyuan! As long as you, Li Mochou, drink this drop of the Demon King's blood, you will possess unparalleled power!
Of course, I was just kidding you. Once you drink the Demon King's blood, hehehehe...
I am the Demon King, I speak for myself, and the more I enslave, the stronger I become!
