In a room fitted with a one-way mirror, Chu Jun and Li Xiu were watching a person inside through the mirror.
Inside the prison-like room, the walls, table, chairs, bed, and even the sheets and cups were all black.
The person sat in a chair, staring at the teacup on the table, muttering quietly to himself, so softly that it was impossible to hear.
Li Xiu and Chu Jun had been watching for more than half an hour, and during that time, the person simply kept staring at the cup and muttering, never standing up, his body exhibiting a bizarre Parkinson's-like tremor.
"Mr. Chu, he's always like this, except when eating, drinking, and sleeping," a Red Sand City official accompanying Chu Jun said with a smile.
"Can we go in and talk to him?" Chu Jun asked.
"Of course, but he's quite out of touch and doesn't understand human speech, so communication might be difficult," the official said and led Li Xiu and Chu Jun to the locked door, opening it: "Please, come in."
