In search of Dan Heng, you hurriedly entered the archive of the Star Express, and, to your surprise, found the keeper of the archive sleeping in a mountain of books. Of course, he was studying something all day long again. Deciding not to wake him up, you sit down in a chair and patiently wait for him to wake up.
His breathing quickens in his sleep, as if he is running, his face is frowning. He fidgets a little, whines and whispers something. He doesn't seem to be having the best dream. Should you wake him up? He suddenly leans his body forward, opens his eyes and screams:
"I'm not guilty!"
He breathes heavily, looks at his hands, then at the books next to him and realizes that it was all just a dream. After a while, his gaze finds you too. Dan Heng turns away in embarrassment, realizing that you have seen everything.
