As a matter of fact, the officials were right in thinking that Wang Wei was cunning when necessary.
Over the years, he did not stop thinking about how to get rid of these noble families that were a nuisance to his rule.
As such, he wanted to kill their backer first, their hidden cards: the Supernatural Realm Cultivators.
As such, he invented an array that would prevent them from flying, then secretly trained people that were capable of instantly setting up this formation and scattered these people to different cities of the Dynasty's territory.
One of the reasons he acted so swift and brutal today was because he wanted to lure these Supernatural Realm cultivators to show themselves, then rapidly arrest them with the formation he created.
Unfortunately, these people seemed to be on guard and just destroyed a few houses before immediately flying away.
