Jiang Yi didn't have an epiphany!
However, while watching this Heaven Painting, he was inexplicably touched and engrossed in his own world. He forgot about the time and about everything. Naturally, Jian Wuying's laughter didn't startle him.
The techniques of the first Heaven Painting wasn't very sophisticated and was far worse than the Heaven Paintings after it. Perhaps, precisely because of the lack of skills, the things that this Heaven Painting wished to express were clearer than those of the other Heaven Paintings. Or maybe Jiang Yi's mother was in the Heaven Painting so he had a deeper feeling towards it.
In the painting, the Buddha Thearch and an Elder in a gray robe were fighting on a barren field. Yi Piaopiao stood on the peak of a mountain far away, wearing a faint smile as though she was just an audience on the stand.
