Well, he forgot that archery, horse riding and sword art were the essence of Chinese martial arts.
Archery was one of them and was the most important of them all!
Wang Yu began practising martial arts at 4 years old and by 10 years old, he was adept at archery.
Putting a large target like Dark Demon Dragon aside, even if it was a flying sparrow, he would be able to shoot it.
However, once an arrow was sent out, it would kill. In the lawful society, martial artists' duels were not life-threatening. In their usual weapon fights, they would use weapons made of wood so archery was naturally not convenient to be used for competitions.
Hence, compared to a bow and arrow, Wang Yu preferred to use his fists and legs.
