Howard exercised according to a routine Lorist had given him that had the effect of enhancing one’s fundamental capabilities and physique.
When Lorist left for the Hanayabarta kingdom, he had stopped Howard from accompanying him on the campaign despite the latter's insistence. Given the dangers involved, Lorist would not be able to spare extra effort to look after Howard during the conflict. But Howard had maintained that given that he had broken through to the iron rank, he would be more than capable of defending himself from some random soldiers.
Lorist merely smiled at his disciple's response and got Reidy to start training Howard to develop dynamic vision, which Lorist stated was one of the main requirements a disciple of his had to fulfill. Given that Howard was already an iron rank, Lorist advised Howard to take the chance during his absence on the expedition to develop dynamic vision.
So, Howard left with Reidy in the end. When Lorist returned to the dominion, Reidy reported to him that Howard had indeed successfully developed dynamic vision. However, given the difference in physical traits between Howard and Reidy, it took the former up to half a month before he got used to the vertigo-inducing ride on the spinning chair, the embarrassment of which prevented him from coming to see Lorist himself.
By the time Lorist arrived at the training grounds behind Firmrock Castle, he saw Howard training in swordsmanship. It was apparent that his swordsmanship had improved quite a lot following his development of dynamic vision. Lorist was rather satisfied with the results and felt that Howard would be more than capable of taking on silver ranks in another two years of training.
