Li Ying involuntarily let out a bellow full of True Force that echoed within the vast volcano, but Chu Feng's figure was still elusive, no longer visible.
The expression on Dai Sheng's face also turned to a steel blue, no wonder the masked kid had been smiling so brilliantly just a moment ago.
It turned out he actually knew an invisibility class secret technique!
Dai Sheng mistook Chu Feng's trait, Wind Concealment, for a secret technique, but his psychological guess about the latter was not wrong.
Chu Feng was full of confidence that if a group of people were surrounded, he would definitely be the one to survive till the end.
Since he could hide his form, and the Iron Chain Demons were not good at using spiritual power, it would be very hard to detect him unless there was a physical collision.
Now Dai Sheng felt both anger and regret in his heart. Had he known that the masked kid had such a miraculous secret technique, he definitely would have treated him well!
