The Heavenly Emperor was preaching the Dao.
The entire sermon lasted for a total of three periods of three thousand years.
During the first three thousand years,
He imparted the Nine Transformations Dao-Proving Method, lecturing on how to execute the nine transformations and how to transition to cultivating the Nine Transformations Method.
The profundities of the Dao and its laws were fully manifested,
captivating and intoxicating all who listened.
