HOW could Luo Yan not know? He hadn't removed his gaze on the original since the other threw those two leaves. That's why even if two more copies of him appeared and tried to confuse him, he still knew who was the real one.
He sensed an attack coming from the left. He raised his dagger and repelled it. It's a good thing that he was using double-wielding weapons. It was easier to repel attacks from all sides. With his speed, he barely received any major damage.
The orange-haired kitsune – the real one – raised his katana as if preparing for a big attack. Luo Yan finally found his opening. Before the other could do his 'big move', he quickly used one of his skills – [Strike Kill].
It was one of his more powerful skills against a single enemy. His hit landed and the kitsune was thrown off quite a distance. His back hitting a tree. The two fake kitsunes suddenly turned into flames and disappeared.
