Why is Tian Boguang so strong in "The Swordsman"?

The purpose of setting Tian Boguang to be "powerful" is for plot needs.

Tian Boguang in "The Swordsman" used his sharp sword to appear "strong" in martial arts in the early days, purely for the needs of the plot. His martial arts must be just right and cannot exceed that of the monk who is not disciplined, otherwise the monk who is not disciplined will not be able to threaten him to go to Huashan to find Linghu Chong.

At the same time, he must be much more powerful than Linghu Chong, who just appeared, so that he can attract the big boss behind the Huashan Sect, the senior swordsman Shen Feng Qingyang. With Feng Qingyang teaching Dugu Nine Swords, Linghu Chong was able to transform himself from a second-rate weakling in the world to a top-notch master.

Tian Boguang’s strongest point is not his martial arts skills, but his nose.

For Tian Boguang, who travels alone for thousands of miles, picking flowers and Qinggong are not his best skills. His ultimate trick is to recognize a woman's hiding place by scent. Being able to find the hiding places of the Hengshan sect nuns with the help of his nose is Tian Boguang's greatest skill. This ability can only be compared to the roaring dog of Yang Jian, the true king of Xian Dao and Erlang Shen.
