Yang Dao looked at the king of flames. He did not use the fire element just now, because he was aware that this was not the full strength of the old man. He was just testing the waters with his earlier attack.
The flame king had not retreated because of the impact of his punch, but it was at his discretion. By opening a gap between each other, he will be able to get a better chance of attack, while at the same time he can make Yang Dao have the illusion that he could suppress him.
Yang Dao admitted in his heart that this guy was not the ordinary joe. He had the skills at both physical and mental levels. The small schemes set the ground for a big scam. The scam was to let the opponent think he was weak and then, like a viper strike when the opponent thinks that the fight has ended and relaxes.
