I'd go for Wuyazi.
In bare medical terms, his disciple, who had a fraction of his skill and none of his martial arts, had a reputation as a divine healer. So WYZ's medical skills are at least an order higher. Plus he had 70 years of Beiming internal, which is the most neutral internal around. Xuzhu had more internal, but how much of WYZ's medical skill did he have?
Basically this. Su Xinghe claimed he only got a fraction from WYZ.
And XZ after reading some XY books, can re-attach optic nerves with eyeball swaps on 1st attempt.
I think a lot of it was leftover mess from 1st edition when XYP was written by JY like some out of this world magical fairy sect where WYZ could only comprehend less than 20% (stated in 1st ed. text) of the main XY manual.
Its BIxie Jianfa Gawdammit you guys!!!!
