This was because World Sources could only be used by worlds and their creators.
Otherwise, after Great King Qingzhi invaded the Giant Realm, how could he possibly have left the Giant Realm's World Source untouched?
Moreover, the use of World Sources was restricted.
For example, a low-level World Source could not be used on a high-level world.
Take Xu Zimo's Divine Continent. Its World Source was a Large World Source.
If it wished to absorb other World Sources, they had to come from similarly large worlds or from giant worlds.
Small World Sources and Medium World Sources were useless to the Divine Continent.
It was precisely because of this restriction
that large worlds were prevented from plundering small and medium worlds as they pleased.
Otherwise, if every kind of World Source could be used,
then all the small and medium worlds in the universe would likely find it difficult to survive.
That would become a disaster for the entire universe.
To large worlds, today's small and medium worlds were more like colonies.
They constantly plundered those worlds' resources,
feeding an endless supply of blood to the great worlds themselves.
This was a long-term mode of development.
And Xu Zimo could make use of the World Sources of such Small Worlds.
After speaking with Great King Qingzhi for a while, Xu Zimo gained a fairly good understanding of the surrounding environment.
In truth, the stretch of cosmic spacetime where the Nine Domains World was located was quite decent.
It was far from both the Undying Star and the Underworld King Star.
There were no particularly powerful enemies nearby.
Around the Nine Domains World, there were seventeen worlds of varying sizes in total.
These were the findings Great King Qingzhi had gathered after taking control of the Giant Realm.
Among those seventeen
