[Traditional fantasy + no female lead + hidden identity + decisive and ruthless] Shang Xuan transmigrates to a martial arts world and becomes a direct descendant of a family in a minor dynasty.

Then, in a sudden moment of enlightenment, he comprehends the way of cultivation instead. In a martial arts world, you expect me to cultivate immortality?
