After Su Ruoxue's patient explanation, Jiang Yi finally understood the entire situation. But as he listened, he got flustered.
The day that he made contact with the restriction on the Divine Monument, he felt as though he realized something within his heart; but it was blurry. He didn't expect himself to really have the realization of the Massacre Intent. He even used it at the most crucial timing to slay the Ice Beast.
According to Su Ruoxue, when his Massacre Intent was released, the Ice Beast didn't even dare to move and was easily slain by him. Jiang Yi was skeptical since he went into a frenzied state by then. He didn't know what was he doing and why such a formidable beast like the Ice Beast was frightened by his killing aura.
