Although the back of the mountain of the Academy was the only one which was involved in the secular world, it was still an Unknown Place. It was kind of mysterious to most people. Few people knew what it looked like or who stayed there because, since Ke Haoran, people from the Academy hardly ever showed up in the secular world.
Not to mention the people in the secular world and the West-Hill Divine Palace, but even the Zhishou Abbey, Xuankong Temple, and Devil's Doctrine knew very little about the back of the mountain of the Academy. All they knew was that there were 13 core disciples studying there with unfathomable abilities.
Second Brother Jun Mo and Chen Pipi were the most famous ones among all the core disciples in the upper circle of the cultivation world. Second Brother was famous for his pride and confidence while Chen Pipi was famous for his reputation as an unrivaled cultivation genius and was recognized by Zhishou Abbey when he was born.
