This person had masked his aura, making him appear as an ordinary human. His eyes were cold and sharp as blades, making them hard to look at.
This person was Yang Yidao, who was supposed to be going after Gang Dalei! He had not stepped out of the Great Thunder Hall but instead hid just for this moment.
"I had faintly sensed someone observing us from outside the barrier back at the secret chamber," said Yang Yidao, his tone surprised as he observed Su Yu. "Combined with what Gang Dalei said, I thought the legacy of the Thunder Emperor would be obtained by someone who came earlier. I had thought that it was the lad using the curse techniques. After all, his abilities are decent, and his techniques are rather weird. But I did not expect that person to be the weakest of the three wandering cultivators, you! This is truly unexpected!"
