The light green source energy in Beck's body had an innate affinity with plant-type source beasts, making them easier to tame. It could also speed up the advancement of an item-type source beast's realm.
What surprised Beck wasn't the strange-colored source energy he was exuding, but the fact that the source energy in his body was actually so rich. This made him extremely surprised.
That was because the quality of the source energy emitted from Lugh's body was already comparable to that of a high-level source beast Beast Master.
This kind of talent was rare even in the Beast God Sect. For a time, Beck valued Lugh even more.
Actually, Beck didn't know that this was the result of Lugh being able to conceal his strength and shift his pet.
Since he had to reveal his talent, he had to keep his true trump card. This was the most mature method.
After achieving his goal, Lugh withdrew his source energy and looked coldly at the furious Oliver.
