Twitching his eye, Di Tou watched the last flower move into place after he adjusted the formation to confirm that it was correct and took a deep breath. Today, in order to suppress the Yin Body in Brother Wu's body, not only to save Brother Wu but also to give himself a shot for advancement, he had set up a three-layer formation, although it wasn't perfect.
Essentially, he was still setting up a two-layer formation but was then using his spirit needles to supplement the individual Spirit Frost Flower octagons. While this created some imbalance in the formation and made it rather fragile, it also gave it a rather hefty boost in power.
A white light floating in his vision, Di Tou couldn't help but blink once more before waving his hand down, summoning all of the needles and flowers into play, striking them down around Brother Wu.
