What is the name of Zhang Jiao's three-volume gobbledygook?

There are two versions of gobbledygook at present. One is from the sixty-eighth chapter of the Romance of the Three Kingdoms. Cao Cao asked Zuo Ci, "What magic can you do?" Zuo Ci replied: "I have been practicing in Emei Mountain all the year round. Suddenly, Lei Zhen has a broken stone wall, revealing three volumes of heavenly books, which are divided into three volumes: heaven, earth and man." Second, Zhang Jiao met an old fairy from South China in the mountains. The old fairy from South China gave Zhang Jiao three volumes of gobbledygook, which were divided into heaven shield, earth shield and human shield. After learning from them, the three brothers Zhang Jiao established the Yellow Scarf Sect and finally launched the Yellow Scarf Uprising.
