It happened once by mistake when they were fighting a boss with his previous pro team. So he took notice of this and now such coincidental info came into play.
As for Hao, he left the right sided monsters to them to handle and took responsibility for the central group.
This time he wasn't just evading, but also fighting. He knew he had to clear this group before the remaining monsters would come here.
After all, the remaining monsters from the left side wouldn't stand in their hall silent. All the paths here were interconnected. And he estimated for them to take almost a minute to come back through the right sided tunnel.
And during this minute, this group of monsters must fall one way or another.
So even if his skills wouldn't bring them down, they would take a bit of their health bar at least.
"Focus all your healing skills on me," Hao knew how tired he was. He felt like he returned back in time, when he was battling a fierce pro team in an official tournament.
