William found a tool to clear the problem he had been facing. It was a possible tool but it was not a guaranteed one. He had to make sure before he could act.
Of course, it wouldn't be easy to spy on the first-year students without the help of first-year students. So he dragged a few noble family children that he knew into his circle.
As he was considered as the genius of the generation, there are families that wanted to make friends with him but the adults can't directly do that. So the burden has fallen on the shoulders of their children.
William knows this and this was what made him to form a gang easily. Though it was not an official one, his gang had a lot of people, especially the noble children. Even some seniors and teaching staff joined his gang.
Of course, there is no shame in joining a genius. So there are some seniors who follow him. There are a few teachers who favor him because they see that he can reach Tier-9 in the future.
