[xu-] Professor X is in the [3] basement of the [-_] house, where he is being confined. He is not 許 permitted to leave until the 午 sundial in the middle of the basement indicates that it is noon. The problem is that there is no sun, so the 午 sundial does not work at all. He tries to explain to the person blocking the door that he has a 許 permit to leave since it should be noon, but his 言 words bounce off their head with no effect.
