Tianlong Yun's words would be nothing more than a joke if he hadn't just killed another level 3 Boundary Ascension powerhouse not long ago.
But with that guy dead to make an example, the old man didn't know if he should take this opportunity or not.
If Tianlong Yun was just bluffing he had full confidence that he could bully this kid to death, but if he wasn't then he would be sending his life to him on a golden plate.
There was no way he would want to die, but thinking about this a little bit more, if Tianlong Yun could have killed him then wouldn't he be dead already?
Most probably what he had done earlier was just a one-time thing. Most probably he couldn't do that again, so he was bluffing.
But if he was bluffing then for what was he bluffing for? For time? Wouldn't that just be a stupid thing to do?
