In total, the old book titled "The Age of Gods and the Four Divine Clans" cited the existence of a total of thirteen realms of power.
Qi Gathering, Blood Condensation, Tendon Hardening, Bone Forging, Meridian Widening, Consecrated Immortal, Sea Expansion, Foundation Forging, Golden Core, Soul Transformation, Life Star, Netherpassage, and lastly, Heaven Merging.
Although there were only thirteen realms in the old book, the person who wrote it clearly stated that beyond Heaven Merging there was at least one more realm; probably the realm in which one would become some sort of god among mortals or something like that.
Reading the thirteen realms, Bai Zemin felt complicated emotions in his heart.
On one side he felt happy that he had read so many light novels of cultivation genre during childhood and adolescence. Thanks to this abnormally powerful hobby of his, he now had at least a few ideas of what he could run into later on in his life.
