The unlocking sound of the door aroused Zhang Tie's attention as he instantly let go of the two bizarre energies that he had tried to gather for many times.
After that, Zhang Tie opened his eyes as he saw the two immortal generals of the Supervision Department who brought him here three days ago.
"Zhang Tie, you could leave now!" one of the two immortal generals said politely with a smile. Both of them looked peaceful.
During the past three days, although Zhang Tie was in the cell, he was crystal clear about what had happened in Dragon Emperor City. During this short period of time, Zhang Tie would travel across those top boites in Dragon Emperor City at supper time spiritually and listen to what immortal generals were talking about at the table.
