Zhang Yang stopped less than 20 steps away from Zhang Tie's room. At the sight of Zhang Yang, two fighters at the door chested out and looked forward.
If not Zhang Yang was sure that he was healthy, he almost thought that he got a phonism.
However, Zhang Yang knew that it was not phonism, but a secret voice transmission skill used by knights. Now that the one in the room knew that he had arrived from so far away by ears and could talk with him in secret voice transmission skill without being discovered by his knight bodyguard, it meant that the one's overall strength had surpassed the knight bodyguard on his side.
Zhang Yang's heart raced. When he stopped, the two followers also stopped as they watched him with curious looks.
In a split second, Zhang Yang had considered well some things.
"Is that man inside the room?"
"Yes, he's still inside and waiting for colonel!" The military officer on Zhang Yang's side replied.
