When Ye Futian observed the Nine Heavenly Strikes all those years ago, he witnessed how attacks were made with the staff techniques. While he was unable to fathom the intricacies within back then, he had committed what he saw to memory.
The moves had continuously gotten more powerful throughout the years through his training.
At present, the seventh move of the Nine Heavenly Strikes was melded with the great path, crashing down with immense power.
Despite being only a Saint of True Self, being melded with the great path at the moment meant that his attack would not have been any weaker than those of Unblemished Saints. With starry power and the way of Entropy incorporated within his staff techniques, the damage dealt in an instant was nothing short of frightening.
