However, the mastery level of these beasts was not very high. It was only through their mutual interaction and verification that Lin Ping'an was able to raise the mastery of each rule to the current level.
Most of them reached around thirty percent. To improve further, he would need to insert another batch of Beast Kings into his Little World.
The rules-related knowledge acquired from refining must not overlap with what was already known in order to improve progress.
Put more simply, if the full mastery of the rule of gold is 100%, and this Beast King understands 10% of it, after Lin Ping'an refines it with the Great Sun Furnace Scripture,
those 10% of mastery would be extracted and stripped, completely belonging to Lin Ping'an's control.
Then, if a second Beast King also understands 10% of the rule of gold, but 5% of it is overlapping content, once Lin Ping'an refines it, he would only gain 5% more mastery, raising his control from 10% to 15%.
