After the black-robed man had committed suicide, Zheng-Fu brought his body back to the restaurant because he wanted to check something.
Of course, what happened outside, there would be people who witnessed this event, and seeing that Zheng-Fu brought the figure of the black-robed man into the room, a crowd of people started to gather and chat about what had happened.
Aside from the people in that area, the cultivators in the city were all aware of it because of the energy waves released by Zheng-Fu. And they could perceive the energy to be extremely strong, especially within the Beyond Earth Sect, the gathering place of the cultivators.
“Who does this energy wave belong to? Why is it so strong?”
“Even Sectmaster Dong wouldn't be that strong… Or a martial master from another land coming to this city?”
“Damn, how could it be like that!?”
