This time, Chu Linfeng's voice was clearly heard by the three women. The sound was indeed inside this room, but the room was so large that it couldn't escape the divine sense inspection of the three women.
There are only two possibilities for such a situation: one is that Chu Linfeng can become invisible and merge his body with the air, making it impossible for anyone to detect him. However, it seems he can't do that.
The other possibility is that he is underground at this moment, but the floor in this imperial palace is covered with marble, a very hard material. Moreover, there's no possibility of an underground tunnel or such for him to hide beneath, so this situation is also unlikely to occur.
The three women silently looked at each other, all feeling puzzled. It was clear that Chu Linfeng wanted to give everyone a surprise, but the surprise was indeed too unexpected.
