After successfully creating it, Du You didn't need to continue making more. On one hand, after these two creations, Du You gained a deeper understanding of light and dark elements, and his comprehension of the Law had already succeeded.
Continuing to make new ones had no real significance for his own improvement.
On the other hand, since this was his territory, once creation was successful, it was already recorded in the territory. In the future, if he wanted a new Elemental Lord, he just needed to spend more points, although these points were not a small amount.
However, modification was possible, which involved transforming the divine soul of other Elemental Lords into other element types. This cost even more than direct creation, and for now, Du You didn't have that many points to waste.
And the next step in research was much more troublesome than researching light and dark elements, and would take a longer time.
