The trio was cultivating in the Nine Heavens Painting for the last eight hours now.
While Jun Xie and Zheng Xiang were quite confused at how this place was going to help them in increasing their cultivation, Ye Tian Yun just said to wait and watch.
With no other choice, they could only focus on their own cultivation.
As for Ye Tian Yun, he too was focused on his cultivation. The reason why he chose to stay in the painting instead of getting out and cultivating in the Cultivation Space was that he wanted to see the time dilation in the Nine Heavens Painting.
Another reason was that Jun Xie and Zheng Xiang wouldn't be able to come out of the painting on their own, and right now, they were unaware of the time dilation. After eight hours, they would think that night had passed, and Ye Tian Yun wanted to witness the amazement on their faces, the same expression which he, himself, had when he first got out of the Cultivation Space.
