However, Zhang Jiao acquired the "Essential Arts for Peace" taught by Zhuang Zhou, and although the method of becoming immortal was excluded from the "Essential Arts for Peace," the Taoist arts were all-encompassing within it.

After about a year, he had mastered Taoist arts to the point of being able to summon wind and call rain. He took the Taoist name "Taiping Daoist," established the "Taiping Sect," and comprehended the "Essential Arts for Peace" along with his two older brothers.

Their cultivation in the Taoist arts was nowhere near as formidable as Zhang Jiao's.
