I let them go

Old Yen led Wu Long to the location of the ambushers first, since it was more likely to be erased first.

"Um... that technique..."

On the way there, Old Yen reluctantly asked.

"The one I used? It is called the Jade Palms of Agony, a technique that, if utilized correctly, could bring a gruesome end. But without skill, it is only useful at giving internal injuries without outer signs"

"So they will die"

Old Yen sighed with relief at the word "end" since it meant that the torturous experience they were going through would end.

"Eventually, of course"

"E-eventually? How long does it take?"

"Different for everyone, and also depending on the spot I hit or the way I utilized the technique, but once they cry out enough blood for them to die of bloodloss, they of course will die"
