is an oath: self-entry into the door, dedicated to mysticism. Feel heaven and earth, and have mercy for life. Lang Lang Qiankun, has its own law. Defend the right and ward off evil, not afraid of life and death. Slaying demons and eliminating demons is where the duty lies. If this oath is violated, five thunders will hit the top.

My name is Zhang Shiyi and my date of birth is unknown. My age is not a secret, my background is a secret. Because I am an orphan. For as long as I can remember, I have been at the Zhengde Orphanage in Sancai City.

At the age of sixteen, I became a Taoist student. A monthly allowance of 500 yuan can be received from the Taoist Association. Of course, since there are rights, there are obligations. My obligation is to start recording my life from the day I become a Taoist.

This is the origin of this "Notes of the Flat Demon".
