The four Immortal Swords formed a Sword Array, rendering the butterfly incapable of movement. In the void, a seven-colored radiant tower illusion descended, enveloping the butterfly, and immediately the light and shadow on the tower rapidly shifted.
A peculiar expression appeared on Cangwu's face as he discovered the tower's master was attempting to analyze this butterfly. This was one of Cangwu's trump cards, one that once chased a Perfect Imperial View for several months before it finally couldn't escape, falling to the butterfly.
The tower master is still merely a Dharma Image; how dare they attempt to analyze Immortal Means? As for the Sword Array formed by the four Immortal Swords, Cangwu had heard of it before. It wasn't surprising it could confine the butterfly, but he hadn't thought anyone could set it up while still a Dharma Image.
