Gong Qiying's initial design for Big Tree Hole was a whopping thousand kilometers high.
Later, feeling that this data was too exaggerated and discouraging, even for the Fall-resistant King to endure, it was drastically reduced and the height shrank accordingly.
In this descent of the Exploration Team, they approximately skipped one-tenth of its height; the remaining distance was still hair-raising.
The crisscrossed roots were thick and thin, smooth and rough; to ensure a safe rapid descent, one must carefully ponder each foothold. If one were to jump and then fail to stand steady due to the slippery roots, causing a situation like Robert's—it would indeed be interesting.
