Xiao Lin spent two days in distress. Had he not stayed in the room while resting and waiting for Song Junlang to deal with things, Xiao Lin might have given up on the necromantic meditation technique.
He also understood why the course was not offered in the entire four years of study. Instead, it was only placed in the library for interested students to borrow, and even then, there were few who actually borrowed it to study.
Since Xiao Lin's mindset was to pass the time, he felt that he should continue trying harder. The first thing he did was search for anything relevant on the forum. Since he had a pass to attend whatever class he wanted, he could read the curriculum schedules of other grades as he pleased. It was a pity that his search came up empty.
