The Great Dao of Life is opposite to the Great Dao of Death.
If one harmonizes with these two Daos, they can reach the Seventh Rank, but this is the highest realm attainable.
To advance further, one must unify life and death, controlling both in mastery.
Chen Mobai's third senior brother in Purple Cloud Palace has harmonized with this Innate Life and Death Great Dao.
Once the Life and Death Great Dao is claimed, theoretically, the Great Dao of Life and the Great Dao of Death should also belong to the third senior brother. This is the absolute control of the Innate Great Dao over the extended Acquired Great Dao, but some great abilities disdainful of these will leave the Acquired Great Dao vacant intentionally, or let cultivators harmonize with it.
Like the Demon Lord, who uses this method to fish for talent.
Of course, there is another scenario, such as between master and disciple.
