Wei Yuan reviewed the relevant information in his mind. The Xui Family was one of the Seven Surnames and Thirteen Hopes, with their main influence in the central and western parts of Ning State. It had been less than two thousand years since the Human Clan had taken the whole of Ning State, so the Xui Family was considered new nobility, ranked at the bottom among the Gate Valve in terms of strength. A few years ago, the territories a few thousand li to the west of Han Yang Pass were all under the Xui Family's power, where they had established a Grotto Heaven. Both the government and the Sects had intricate ties with the Xui Family. However, after the entire region had fallen to the Wuyu Clan, the Grotto Heaven shattered, greatly damaging the Xui Family's Primordial Qi and directly stripping away twenty percent of their strength.
