Bai Li looked at Shihong on the floor in a pitiable state and he knew who did it. She was a bit cruel to her own standards but it doesn't matter anymore. What matters is finding Old Rong.
Old Rong has become too weak that no one could detect him like they would detect a god and most of them don't know, how the weapon he was trapped in looked like. They had a general idea that it was a halberd but the true appearance of that halberd, no one knew and the Tianshi Emperor made sure that only he knew Old Rong's true form.
Bai Li looked around to see various weapon and there were at least fifteen halberd in that room and how could one find out which is containing Old Rong?
Bai Li saw Chenglie and Xing there in the corner.... Doing whatever!
