After the invention of the "demon school', the people most affected were the other Emperor Lineages as they were also trying to find a way to control this aspect of Merit and Qi Luck of the concept of school. Unfortunately, Wang Wei was prepared beforehand and got there before them.
Many people did not expect that the Dao Opening Sect would use the Fox Demon clan that betrayed the Demon Race more than a century ago. As such, many people started to wonder whether Wang Wei planned all of this back then; back when he was like 8 years old and invited the Fox Clan to help him refine the Pagoda.
Unfortunately, these people gave him too much credit. To achieve this plan, a great deal of knowledge and information regarding the workings of Qi Luck is needed. And Wang Wei only reached that level during his Qi Luck Trial after his Luck turned from black to Gold.
