Wang Qi actually had some impression of the face in front of him. This Core Formation Cultivator was indeed the first Ancient Method Practitioner he fought with Mi when they followed Lian Xinjie and Lian Xingling to Spirit Phoenix Island, and still a Core Formation... Remember, hmm, what's the name again? Jia something...
The memory of someone at the Golden Core Stage is very strong, even a fleeting glimpse can be remembered. However, Wang Qi has always treasured his brain capacity tightly, and apart from deliberately relaxing his spirit, he hardly concerns himself with insignificant matters. The cultivator in front of him was merely in the Core Formation Stage, not affecting his task in any way, hence Wang Qi had almost completely put this person out of his mind.
If it wasn't for the subtle spiritual power fluctuation on Jia Chenglie indicating the existence of an original Divine Plague Curse Technique within him, Wang Qi wouldn't even remember him.
