Shi Feiyang found the Formless Immortal Escape extremely mystical, quite different from the escape skill described in "Guang Chengzi's Heavenly Book," and felt greatly inspired, exclaiming without reserve, "This is wonderful."
Jiang Shu said regretfully, "It may look good in writing, but no matter what, I just can't seem to master it."
"Why can't you master it?" Shi Feiyang asked him to try practicing, and indeed he couldn't achieve invisibility. He then asked Jiang Shu for his understanding of this escape skill, and after listening, he pondered for a moment and then suddenly laughed.
