Something is wrong!
Su Ping was watching Nie Huofeng and the Curse-Winged Beast's battle in the secondary space while standing outside.
Even though Nie Huofeng had won the first clash—and the Curse-Winged Beast's spell force on the wings didn't hurt him, which was a testament to the first-generation Tower Master's great strength—their conversation gave Su Ping a bad feeling.
Their dialog in the second space was a telepathic one, because that region was essentially a vacuum and no sound could be transmitted.
So, it was impossible for Su Ping to tell what they were talking about by reading their lips.
Nie Huofeng currently didn't seem as casual as before; the Curse-Winged Beast, on the other hand, looked as though it were a completely different creature. It had an extremely relaxed appearance!
They were both standing still, but their change of expressions indicated a telepathic communication.
