Ancestor?
Su Yu was slightly surprised.
He now understood that ancestor was the title of the Heavenly Dao Master of the previous era.
Anyone who reached the Heavenly Dao master level had the right to be called ancestor.
There were strong and weak ancestors as well.
Even the early stage of the Heavenly Dao master level had several levels.
Not to mention the middle stage, late stage, or even the perfect stage of the Heavenly Dao master level?
The early stage ancestor could only be said to be an ordinary ancestor.
Only after reaching the middle stage did one have the qualifications to be proud of the world. For example, the nine most outstanding middle stage ancestors were known as the nine great saint ancestors.
Of course, the number one saint ancestor, Ren Zu, had already surpassed the middle stage and reached the late stage.
The slave ancestor in front of him was an existence who had broken through to the Heavenly Dao master level in the previous era.
