In the ancient records of the Heavenly Dao sect, there are a total of three prophecy books in the world, one of which is possessed by the Heavenly Dao sect as an heirloom, controlled by generations of sect leaders.
That year, Tan Wuji and Yu Hengtian were not so much competing for the position of sect leader, but rather for the control of the prophecy book.
After all, the Heavenly Secret Technique cultivated cannot compare with the prophecy books that have the power to glimpse into the Heavenly Dao.
According to rumors, a prophecy book has always been circulating in the Eastern Divine Realm; the Heavenly Dao sect has tried several times to retrieve it from the Eastern Divine Realm, but due to unresolved internal strife and a lack of unity within the sect, action has always been delayed.
As for the last prophecy book, there has been no news for millions of years, its whereabouts unknown.
