Each time Qin Huaian used Grand Void Birth and Extinction, he simply could not control the power of the move. Every use directly drained nearly ninety percent of his Immortal Essence Power, making it truly worthy of being called a "finishing move."
It ended the enemy's life—and also cut off his own retreat.
This was a true "one-move hero"!
If the enemy was not killed, or if there were other enemies nearby, then it would be difficult for him to escape.
Just like when that assassin sent by Autumn Cicada had tried to kill him. Qin Huaian's move had failed to kill his opponent. If Star Pavilion had not arrived in time, he would likely have run into serious trouble.
If he could cultivate this move to the point where he could control the amount of Immortal Essence Power it expended and regulate its might, then Qin Huaian could deploy it according to his needs.
Even if a single sword strike failed to kill the enemy, he could still retain some strength to think of other methods—or flee directly.
Of course, Qin Huaian had considered this issue as well. He guessed that comprehending Grand Void Birth and Extinction likely required a rather high level of understanding of the Yin-Yang Laws.
Perhaps he had comprehended Grand Void Birth and Extinction too early, while his understanding of the Yin-Yang Laws was still far from sufficient. That was why he could not control the move's power.
If his realm of comprehension of the Yin-Yang Laws deepened, his control over the third form, Grand Void Birth and Extinction, should increase as well. He might even gain complete control over this move.
This Limitless Secret Realm should be this place, right? This space was indeed extraordinarily beneficial for comprehending the Yin-Yang Laws.
