As he was working, he decided to expand his knowledge of formations. After all, he doesn't have a body that can innately talk directly with the world through formations.
He has to actually learn the language to use to communicate with the world. In order to expand his reservoir of vocabulary, he has to learn new runes and new formation arrays.
It is easy to acquire a lot of formation diagrams in the sect thanks to the fact that the sect as a whole likes formations and the fact that a Patriarch of the sect is a formation enthusiast who likes to create new formations and purchase strange and exotic ones.
All he has to do is go to the library to get the information he wants. Not many sects have such a privilege.
It will just cost him money to buy the formation diagrams. But he didn't mind the cost because the formation diagrams will also improve the power of the formation breaker.
