In the days that followed, Roger lived through a... strange period.
Most of his time was spent communicating with Higurashi Chika; when resting at Higurashi Gushan, he would also contemplate swordsmanship on his own.
As time passed, the changes in Higurashi Chika became increasingly apparent; the huge cocoon quickly shrank to a normal size.
Sometimes, Higurashi Gushan would occasionally offer a few tips to Roger. He didn't speak much, but often he spoke critically.
Even if Roger continued to ask questions, he was mostly ignored.
With no distinction between day and night, Roger was unclear about the specifics of time passing, but in the process of helping Higurashi Chika, his strength not only didn't decrease but instead steadily solidified in the latter stages of the Fourth Tier.
