It's a pity that nowadays in the martial world, apart from those ancient sects that remain concealed, most of the sects outside focus on cultivating various national arts.
True martial arts are only inherited by those ancient sects...
Such as Shaolin, Tang Sect, Kunlun Sect, among others...
Qin Fang has clashed with experts from both Tang Sect and Shaolin. Tang Nan can be disregarded; he tried to outsmart Qin Fang in their encounter, using either poison or hidden weapons, but neither worked against Qin Fang, and ultimately he died in vain.
From Shaolin, Shen Wuben is considered an expert. Qin Fang exchanged blows with him, just a simple spar, but also witnessed the formidable inner strength of Shaolin, and Shen Wuben is merely a secular disciple.
As for Monk Wukong, his Shaolin inner strength is extremely pure. Though his strength may not appear profound, his power definitely ranks him as the top martial artist just below grandmaster level in Qin Fang's knowledge.
