Nalan Shan came to discover that Wu Jiu's disciples were mysteriously disappearing and one of the first few who disappeared was Wu Jiu's first disciple that he favoured the most. That person possessed great gift and the speed of his progress in cultivation had already surpassed Nalan Shan. But it was not known when it was that that disciple had suddenly disappeared without a reason.
There had been no signs before that person disappeared. Nalan Shan had not noticed that the person had disappeared in the beginning. But as the days passed one by one, the number of human spirits that disappeared increased in succession, and that was when Nalan Shan came to notice that something was wrong.
Nalan Shan went to find Wu Jiu, but this time, he was not even willing to meet with him at all.
Since then, Nalan Shan then fearfully felt the danger in the Serene Spirit Tower and he no longer wanted to take a step inside.
