Eternal Demon Monarch

In the vast world, martial arts is the respect, and ten thousand races strive for hegemony.
Just ask the boundless land, who is responsible for the ups and downs?
He, a young man with a weak crown, was frail and sick since he was a child, and was scorned. Because he awakened the memory of his previous life, he changed his fate against the sky and became a monster.
This is a grand age, with geniuses coming forth in large numbers, so many beautiful beauties, and seeing the young Yang Xuan stepping on the wilds, arrogant to the world, ascending to the top of martial arts, and becoming a generation of devil!
