The Martial King

“Tang Lingling, the daughter of the Tang family, is incredibly beautiful, highly gifted in cultivation, and an alchemist. She meets Yang Kai by chance at an alchemy field. Yang Kai was originally an ordinary martial artist whose dantian was sealed. Later, he discovers that the black essence within him can speed up his cultivation, and begins cultivating like mad.

Once the seal inside Yang Kai is broken, he destroys the demon race. News reaches the empire that the demons have invaded. The black essence within Yang Kai was left behind by a mighty figure from ancient times who wiped out the demon race, and it is specifically capable of restraining them.

To protect his homeland, Yang Kai attacks the demon race, kills the Demon King, and wipes out the demons, restoring peace to the continent.”
