We can deduce the relationship between the Demon Lord and the Demon Lord in the Immortal World Chapter. According to the descriptions in document 1 and document 2, Demon Masters and Demon Lords were existences at the level of Dao Ancestors. They were both very interested in advancing to Dao Ancestor. However, document 2 mentioned that the Demon Lord died after failing his Dao Integration, while document 4 mentioned that the Demon Lord was killed by Han Li.

Therefore, the current search results could not give a definite answer to the relationship between the Demon Lord and the Demon Master.
