But for him, there was not the slightest difficulty.
That was not to say Lin Xuan's comprehension had already reached the point of standing peerless beneath the heavens.
Although his strength was quite impressive, in terms of comprehension, he was merely somewhat above average.
The reason he felt this way was because this Treasure-Controlling Formula came from the same lineage as the main cultivation method he practiced.
That was right. The method for controlling this Xiantian Spirit Treasure and the Ink Moon Heaven Witch Art came from the same line.
The two were fundamentally of the same origin.
And Lin Xuan had already cultivated the latter to an extremely profound level; otherwise, it would have been impossible for him to advance to the Tribulation Transcendence Stage.
