Great Emperor's Different Titles in "Shrouding the Heavens"

The Great Emperor is the highest sub-realm in the Immortal Platform Realm. At this level, the cultivator perfectly combines the five secret realms.

However, the Great Emperor has different titles in different eras.

In the mythological era, the Great Emperor is called the Celestial Being. For example, there are Tribulation Celestial Being and Carefree Celestial Being.

The Undead Sovereign became the Sovereign at the end of the mythological era. He changed the title from Celestial Being to Sovereign. From then on, primordial era started. In this era, the cultivator reached the Great Emperor sub-realm would be called Sovereign.

In the following desolation of the ancient era, the people who reached the Great Emperor sub-realm began to call themselves the Great Emperor, which has continued ever since.

The Heavenly Emperor is a title rather than a realm because his/her strength is so strong that there's a need to produce a title to distinguish him/her from ordinary emperors.
