Xu Wendong didn't expect Han Hexiang to actually care about him. He immediately told him about the events happening in the city and then said, "Master, don't worry. I've set up a formation at my residence to protect myself. You must also stay safe over there!"
Maintaining the formation seemed to be without any danger.

"The situation this time is very grave, I don't have confidence I can survive this calamity," Han Hexiang let out a helpless sigh and then said, "By the way, I have some merit points here, is there anything you want to know? If there is, I can help you investigate!"
