Ye Feng was able to swiftly master the Life Rule, partly because the World Tree Body was compatible with Life Rule and, aided by the system, he could directly comprehend it all at once.
As for the perception of the Space Rule, it occurred when he resurrected the human entity by merging a fragment of the Space Rule, endowing the human entity itself with this specific Talent, thus naturally doubling the effectiveness of his perception.
But now, turning to the Time Rule, neither of the two entities had the Talent for it. Without the capability of the Growth System Plant, Ye Feng wouldn't even have a direction for his perception.
Of course, this is not to say that Ye Feng's Talent was lacking. After all, compared with other geniuses, even by the standards of a peerless prodigy, being able to perceive a Higher Rule within a hundred years was considered quick.
But Ye Feng did not have that much time.
Moreover, Ye Feng's goal was not just the Higher Rule, but the Supreme Rule.
