Why do realms matter in cultivation?
What is the biggest difference between the realms and how can one differentiate between cultivators of each realm?
The first four realms from the Qi formation Realm to the Origin realm are used to cultivate the body.
During each of these realms, a different part of the physical body is refined and purified with the help of the Qi. These realms unlock the true potential of the body, consecutively making cultivators powerful and reach longer lifespans.
After that comes the Spirit Realm where numerous Mind palaces are opened. As its name suggests, the Spirit Realm deals with the working of the spirit or soul of the cultivator, making it stronger with each stage.
Cultivators of the Spirit Realm are able to live for up to 1500 years naturally, although almost none will manage to live that long without getting stronger.
