Zhang Jue is given the Book of Heaven

During one of his journeys into the forest, where he went to gather medical herbs, Zhang Jue (張角) met a mysterious old man. The old man summoned Zhang Jue into a cave and there he handed Zhang Jue three volumes of the Book of Heaven. The old man said:

"This book is the Way of Peace. With the aid of these volumes, you can convert and rescue mankind. But you must be single-minded, or rest assure, you will greatly suffer."

Zhang Jue took a humble bow and then asked the man who he was. The old man replied:

"I am Saint Hermit of the South-Land"

Zhang Jue studied the book eagerly and eventually he was able to summon winds and command the rain. He became known as the Mystic of Great Peace.

What happened historically?
Historically this event did not take place. Zhang Jue did possess a book, but it was called Book of Great Peace, with Green Headings, but it remains unclear to what extent Zhang Jue used it.
