Emrys appeared in front of the cave and looked at the footmarks in the snow.
"They are inside!" he muttered to himself.
An evil grin spread across Emrys's face as the dark mist began to rise from his body, spreading carelessly around him. In a short five minutes, the dark mist had grown denser and covered an area of at least a hundred meters, completely swallowing the surroundings. Within this range, not a speck of light could be seen.
Emrys could have easily killed Zhu Yan, Hao Lin, and Hao Ying if he wanted to. But he wanted them to pay the price for trying to poison him and Xu Ling. Killing them directly would only grant them an easy death, and he wanted them to suffer.
