Of course, right now, the usage of these formations was still rudimentary, and how useful they would be in his later endeavours would have to be determined. The first formation Di Tou had created had been inspired by the breeze formation he had seen the first day, alongside two other formations he had learned on later days when visiting the girl. One was an 'expansion' formation, which created an illusion of space being large. The reason the girl had wanted it was to make her garden larger, so she could enjoy it without feeling like she was in a cramped space inside of the forest. The other was a 'wall' formation, which the girl had set up quite a few of, allowing walls to come up and reshape her house on a whim, changing the dimensions of the interior while also allowing her to create an endless maze.
