What Helian Tiehua mentioned, Ye Qing and Huangfu Ziyu actually knew. The stone formation outside the Xihang Shen Family Manor was built using Qimen Dunjia Techniques. This stone formation is extremely powerful. If you don't understand Qimen Dunjia Techniques and accidentally fall into it, even a top-level master wouldn't be able to escape!
"Qimen Dunjia Techniques are the Taoist Sect's understanding of the rules of heaven and earth. Once these are integrated into martial arts, their power naturally multiplies!" Helian Tiehua said, "The Taoist Sect has a lot of insights in this area, like the stepping techniques of the Heavenly Gangs and Northern Dipper, and this Qimen Dunjia, these are not simple matters. Once integrated into martial arts, their power is immense. In a duel between two peak masters, if one knows more about these techniques, they will definitely have an advantage."
