Chen Fan was startled, thinking someone had entered his room, and quickly turned his head to look around, but there wasn't a second person in the room besides him.
After repeatedly confirming this, he turned his gaze back to the Heavenly Creation Pearl and cautiously asked, "Was that cough just now made by you?"
A voice came from inside the Heavenly Creation Pearl, "Yes, it was."
The voice was somewhat crisp and slightly immature, its gender ambiguous.
Chen Fan had not expected that there would actually be a "person" inside the Heavenly Creation Pearl responding to him, and he was so frightened that he almost threw the dark red pearl in his hand away.
