First of all, it should be said that it is talent, and martial arts needs talent. Just like the phrase "one in a million" in Stephen Chow Kung Fu, Xiao Feng's father Xiao Yuanshan is an excellent master in Dragon. In the first world war outside Yanmenguan, one person almost wiped out the elites of the younger generation of Wulin in the Central Plains. Xiao Yuanshan was an excellent master when he was young. Heredity is a very important factor, which has been proved by modern scientific research. The offspring of tall parents are more likely to grow taller. Xiao Yuanshan has a high martial arts talent, so it is not surprising that Feng Xiao has a high martial arts talent.
The second is to pay attention to training, talent is destiny takes a hand, but whether it can be played depends on personal opportunities. Although Xiao Feng doesn't seem to have any adventures, in fact, his first half life was arranged and cultivated by the elite of Wulin in the Central Plains. Although he didn't eat natural resources or absorb internal forces, his martial arts stood on the top of the rivers and lakes overnight. But as far as training is concerned, Xiao Feng is absolutely no worse than anyone else. When he is a few years old, Shaolin monks will teach him martial arts. More importantly, for Feng Xiao, he didn't know that he was in a sect like Ling Huchong, and Xiao Feng was kept in the dark, so he would have a stronger sense of crisis.
Of course, Xiao Feng's own efforts are inseparable. Here, when Xiao Feng took over as the leader of the Beggars' Sect, he accepted the tests and hardships far beyond those of previous leaders. If Feng Xiao wants to pass this training, it is natural to rely on his own efforts, and it is far beyond ordinary people's training, which is also good for Xiao Feng's growth.
It is precisely because of the above points that Feng Xiao has a good talent, dedicated training, and more than ordinary people's training, which will make Xiao Feng become a top expert in Wulin at such an age.
