Origin, Spirit, and Creation

The Saint realm was a realm meant to prepare one to enter Immortality. It was a realm meant entirely to create a Nascent Soul within one's dantian and have it be merged with the body, thus making the person Immortal.

Similarly, the Immortal realm was also a realm of preparation. Instead of creating a Soul to become Immortal, in the Immortal realm, cultivators had to form their Divine Creation to become a Divinity.

A Creation was the first step of the Divine realm. 

A Creation could be anything, but more often than not, it was something that was intricately linked to a cultivator's cultivation techniques, experience, dao, and many other factors. As such, each one was unique to a person.

Alex had witnessed a few Creations up until this point. Three mainly had made him give some thought to it.
