Two Hundred Sword Eyes

The Sword Eye truly amazed Chen Fei. He had no idea who had created this technique back then, but the concepts and cultivation methods involved were vastly different from many Spiritual Power techniques.

That was right—the Sword Eye was a Spiritual Power technique. Whether driving it or cultivating it, it all involved transformations of Spiritual Power, just like the God Slaying Sword and the Spirit Slaughter Technique.

The difference was that the God Slaying Sword and Spirit Slaughter Technique were meant to kill enemies, while the Sword Eye leaned more toward assistance.

Of course, the Sword Eye's final claim—that it could drag aura out from the past—did not mean it could do so from any point in time. There were limits.

Normally, if one truly cultivated the Sword Eye to its peak state, one could freely capture any aura that had lingered within the past hour, without feeling any strain.

But if someone had a special technique like Chen Fei's Spirit Slaughter Technique, which cut away their own aura, then capturing it became somewhat difficult. Stronger Spiritual Power had to be used to sustain it.

And once it exceeded an hour, the difficulty of capture would continuously rise. But if one's Spiritual Power was strong enough, one could keep expending it to stretch the timeline farther back.

In theory, so long as one's Spiritual Power could hold out, the timeline could be extended without end. As long as one could endure it, there would be no problem.

"Sword Eye simplification in progress... Simplification successful... Sword Eye → Draw Visualization Diagram!"

The simplification fee was not cheap, but Chen Fei did not hesitate before choosing to confirm. There were already very few techniques worthy of his
