"Where is your bestial nature?!" Sword Saint exclaimed as he curved his finger to launch a slash. Another slash was coming in his direction, and the two attacks clashed mid-air.
Noah saw his attack losing against the expert's copy. Sword Saint's slash crossed his ethereal figure without doing any harm before dispersing on his mental walls.
That was the training method decided by Sword Saint. Noah had to launch attacks that the expert copied in their purest form. He then also listed the weaknesses of Noah's slash to instruct him.
The idea behind that training was to force Noah to express every aspect of his individuality in his slashes. He had refused to abandon his other paths, so he needed to fuse all of them into his sword.
That was easier said than done. Whenever Noah focused on his destruction, he failed to add his creation. Whenever he minded only his sharpness, he forgot about his bestial nature.
