2067 "Sky Battle" 

A domain was a new separate dimension from this dimension, but the joint efforts of these many elemental ability users did make the small natural disaster field look like the embryo of a domain. 

Everyone who participated in the making of this natural disaster field could feel some enlightenment related to the secret of creating a domain. 

Many people got stuck in the strength realm before the domain realm, and they could never create a domain in their entire life because to reach this realm, people could not just rely on continuously growing their energy reserve. 

Making a domain involved the rules of space and time, so many people could not make domains even when their strength had already reached the stage of a domain maker. 

This was also why many space element ability users or time element ability users could easily enter the domain realm because they had already touched the rules of space and time before they made their own domain.
