Chen Miao had never known how accomplished Old Ghost was with yin marks, nor had he ever taken the initiative to ask.
Perhaps that had something to do with the yin mark Old Ghost had tattooed on him when they first met.
Ever since then, Chen Miao had held little interest in yin marks.
The only time his interest had been piqued was when he learned that the Mortal World's Demon-Suppressing Bureau's "Ghost Body" was related to Yin Tattooists. But once he discovered that the bureau held the essential secrets to cultivating it, he had handed "Ghost Body" over to Old Ghost to study.
After that, Chen Miao had tossed every yin mark legacy he came across to Old Ghost and never bothered with them again.
Now, watching Old Ghost's fluid, effortless movements, Chen Miao found himself drawn in without realizing it.
Not only Chen Miao-even Xiao Bai, who had seen plenty in the Curse Cult, was watching Old Ghost's technique intently.
As for Shi Manman, although she knew little about it, she also worked with needles.
But compared to Old Ghost, she fell far short.
When Old Ghost wielded his needles, Shi Manman could not even make out how many strikes he made or how many flourishes he performed.
This continued for over an hour before Old Ghost suddenly stopped.
"Done?"
Chen Miao was surprised. He had neither seen any major fluctuations in yin energy nor any scripture appearing on the back that had been pricked.
"Not yet, sir. I still need a ghost."
Old Ghost answered honestly.
Only then did Chen Miao remember that Old Ghost's yin mark techniques involved ghosts.
He immediately pulled over a ghost from Twin Ridge Mountain and tossed it to Old Ghost.
Controlling the Soul Corpse, Old Ghost seized the ghost.
