Yang Yunchong

Description
His name was Yang Yunchong, the eldest son of Yang Lie's grandfather. Originally, my father should have never had a chance to become Lord of Cloud Sky City. Yang Yunchong's talent was even higher than my father's, ranking the first in the whole Northwest Mainland. Everyone thought that he would become the most powerful Lord in the history of Cloud Sky City. At the age of twenty-three, he was already a Xuan Martial Artist powerhouse and was world famous.

But, one day, he discovered the Pig Killing Swordsmanship and was immediately tempted. He used a Xuan Dissociation Pill to unlearn his Chaos Heaven Destroyer Swordsmanship which had reached the Xuan Martial Artist rank. Then, he began learning the Pig Killing Swordsmanship from the beginning. No one could persuade him to stop. He seemed to have gone completely crazy. After that, he transformed from a top genius to a wastrel. Finally, he went completely mad.
