Despite the dark figure being gone, the hall was still chaos as everyone remained vigilant of his or her surroundings. No one knows if the attacker had any other target.
Lu Mang flew into the air and stood in the air, looking down at everyone in the hall. He spread his perspective around the hall, trying to find the presence of the dark figure but he wasn't able to sense the presence of the dark figure.
Finding no trace of the attacker's presence. Lu Mang knew that the dark figure had narrowly escaped, if not he would have been able to sense the presence, nothing in this hall could escape his sense so not being able to find the figure wasn't strange to him because the figure must have depend on a escape treasure, to be able to escape to disappear from this hall.
"YOU BASTARD!" Lu Mang's voice echoed around the hall as he roared. After fruitless searching for the attacker, he stopped.
