Killing Aura is something that's often considered intangible, but the more skilled one's Kung Fu and the stronger their True Qi, the deeper they feel that Killing Aura. Especially when the opponent's strength is greater than their own, it creates a sense of oppression.
Lin Zhi Sanlong's strength had reached the Black Sword Sixth Stage, ranking among the top five in Kikkawa Kendo, and he had absolute confidence in his own power.
He believed that once he unleashed such a Killing Aura, the opponent wouldn't be able to withstand it, and their fighting spirit would decline, making them another one of his defeated foes.
However, reality gave him quite a shock. The three people opposite him not only failed to reach his expected target, but Su Zhentian and Dragon Nine's fighting spirit was fierce, hinting at a strength that vaguely matched his own.
