Li Ming, who was originally an otaku, traveled to Tianxuan Continent. How could an otaku who respected martial arts survive?

How could I help only supporting characters like the proud Yue Buqun and the world-dominating Dugu Ming? Do I not have the destiny to be the protagonist? Why is there the Fire Cloud Evil God from Kung Fu? Hey, this is the villain!
