Logically speaking, such efficiency was quite fast, but for Ye Feng, it was still too slow because he had very little time left.
At most, he had three to four days, which was far from enough.
"Is there any way to speed up the assimilation efficiency?" Ye Feng furrowed his brow.
He tried running the Golden Crow Refining Spirit Method, and although it was effective, the improvement wasn't significant—it only increased the speed by about 10%, which was far from enough.
Then he tried using the Illusion Territory Rule; after all, it was a spiritual power-based Rule, and it should be effective.
This time the effect was much more noticeable, with the assimilation efficiency doubling instantly.
Seeing this, Ye Feng felt somewhat invigorated.
"But even if the efficiency could be doubled, it's still not quite enough," Ye Feng murmured to himself, making one final attempt by invoking the Life Rule.
