"Curses?"
Gui wasn't very surprised. "What kind of curses are you looking for?"
'What kind?' Jiang Hao was puzzled.
"There are different types of curses. For example, there are luck-related curses, which are comprehensive curses that make everything go wrong. But they are not specific, so you might not have control over them. To succeed, you need to pay a significant price. And there are specific curses that can be either instant or delayed. For example, the curse to make someone die a horrible death might happen instantly, but cursing them with no descendant might take effect slowly over a span of decades. I used the latter type on the dragon. I cursed it with decay so that its body would weaken gradually."
"Can I have both?" Jiang Hao asked.
