He slapped his thigh and said, "Ah! So this is the true application of the Blue Flame Silver Needle!"
"I've held this needle for years, yet I've never figured it out!"
"No wonder it's not nearly as miraculous in my hands as it is in our master's."
He hurried forward.
Not daring to interrupt Jiang Fan, his aged eyes stared unblinkingly at his technique.
This scene—
Yan Yuqing was completely stunned.
So, Jiang Fan wasn't performing some kind of cheap trick.
Instead, he was actually activating the true use of the Blue Flame Silver Needle!
As the silver needles formed a specified formation,
Jiang Fan placed one palm firmly downward.
The intricate silver needles shone like strands of blue light as they pierced into the disciple's back according to the predetermined array.
The disciple let out a tortured groan.
Black, ink-like toxins gushed out of his limbs and bones, channeling through the needles before spraying outward.
