A strange tone sounded in his ears.
Su Jingxing's heart skipped a beat. While maintaining his composure, he turned around and looked at the two Bone Demon Beast Half-Demons walking over from the right.
Su Jingxing could understand the Half-Demon's language.
This was one of the gains from watching the memories of Baletudor.
But he couldn't speak it.
It was the same with the demon slaves. He could understand but couldn't speak.
Their speech was not caused by the vibration of their vocal cords. Su Jingxing did not understand the principle behind it, so he naturally could not speak.
As such, when the two Half-Demons walked towards him, all Su Jingxing could do was remain vigilant and chose to keep silent.
"I'm asking you a question. Are you mute?"
Of the two Half-Demons who had come over, the one on the left was slightly taller. At this moment, it was "glaring" at Su Jingxing with his dancing flame eyes.
