The so-called borrowing of the Heaven-Reaching Ladder is a use of the Celestial Ladder Skill. In addition, there are various Array Techniques. None of these are related to secret techniques; they are purely Jianghu methods.
Disciples of the Magic Sect have more or less learned some of these. When traveling the Jianghu and encountering various situations, one cannot rely solely on cultivation of secret techniques.
Disciples of the Xingshen Sect are most skilled in these, followed by the Qi Observation Sect. How could Yu Shangzhen and Wan Zhongle, as high-ranking members of the Magic Sect, not understand?
Wan Zhongle: "Since there's no clear guidance, we might as well pretend this never happened."
Yu Shangzhen shook his head and said, "It's useless. This is the most troublesome part of the Celestial Ladder Skill. Even if Qian Guran is merely guessing blindly, he has already told us, and there were others present."
