Three days later, in the uninhabited land to the north of Mount Shu, Lu Changsheng, Li Changye, and the Taiyuan Ancestral Master appeared at this place.
The Taiyuan Ancestral Master set up a Formation, so that any intruder could easily be detected.
Lu Changsheng's breakthrough to the Void Refinement Realm was a significant event for Mount Shu. The Taiyuan Ancestral Master even went so far as to protect Lu Changsheng in his capacity as Sect Leader.
The eldest senior brother, Li Changye was also called upon by the Taiyuan Ancestral Master to act as a protector.
Without a Mountain Protection Array on the outside, should the four great Demon Sects learn of the recent extraordinary genius Lu Changsheng's Tribulation at Mount Shu, they would surely attempt to interfere.
It was too risky for Mount Shu to allow Lu Changsheng to face the Tribulation alone outside.
