This curse technique can be cast on someone with just a single encounter, which is indeed somewhat peculiar.
Seeing that Chong Hua seemed somewhat interested, Ghost King Xicai hurriedly said:
"This curse is called 'Triple Layer of Suffering'... one layer for the heart, one for the mind, and one for the body. It requires quite a lot of spirit materials and time, but everything else is manageable. Initially, it was the people from the Jade Pot Realm who coerced me into it, and I had no choice. This meeting is also to sincerely apologize to you, Taoist Friend."
As he spoke, he suddenly pulled a pale leg bone from his sleeve. It was engraved with numerous characters, and he forced a smile on his face:
"This is the method to perform the Triple Suffering Curse Technique. Although it is a personal disciple's secret from our Hundred Ghost Mountain, I see that Taoist Friend seems interested, so I gift it to you."
