When the Sky Piercing Black Eagle and Rainbow arrived at the treehouse, Ethen was still engaged in his challenge.
Unable to see its master immediately, Rainbow, under the Sky Piercing Black Eagle's guidance, Rainbow went to Cold Spring near the treehouse to rest and stabilize its cultivation.
The spring water of the Cold Spring contains special substances that are highly effective for consolidating cultivation.
Upon entering the Cold Spring, Rainbow steadied its mind, allowing the spring water to wash over and soothe its body, gradually adjusting and relaxing.
Meanwhile, the Sky Piercing Black Eagle sat in its treehouse, sipping tea and contemplating something.
Time quietly passed. By evening, after finishing its bath, Rainbow rested inside the treehouse. The Sky Piercing Black Eagle continued sipping its tea throughout the night.
By the next morning, the Sky Gazing Mirror sent a message to the Sky Piercing Black Eagle: Ethen had completed 20 levels in the mirrored space.
