After all, a trick is just a trick.
According to Shen Yue, the modern Indian performance of the Sky-Reaching Rope and the levitation using a cane are similar, both employing clever mechanisms. The principle behind levitation is balance of gravity, while the Sky-Reaching Rope relies on the internal mechanism of the rope, which has a snap hook that locks in both directions.
Why can children climb the rope? Naturally, the children are trained and understand the direction of the hook's mechanism. If a heavier person tries, the internal mechanism could be overwhelmed.
Of course, if the material inside the rope is enhanced with high technology, an adult could also climb up it.
In Bianjing, this Sky-Reaching Rope has undergone technological modification.
It is a kind of plant that can quickly grow when stimulated by electricity, and it is extremely tough!
At the top of the plant appears Huyan Mingxin, a trap designed by Du Zijun for Shen Yue.
