Meng Hao did not exterminate the Eighth Sect. He did not take the grief for the Mountain and Sea Realm that lurked in his heart and vent it upon the world. He was not young anymore. He had practiced cultivation and experienced the transformations of time. He had long since lost track of how many years it had actually been.
