至后元二年，武帝疾，往来长杨、五柞宫，望气者言长安狱中有天子气，上遣使者分条中都官狱系者，轻、重皆杀之。
In Houyuan Year 2, Emperor Wu became ill and traveled back and forth between Changyang and Wuzhuo Palace. The astrologer who observed the clouds and air said that there was an imperial aura in Chang'an prison, and Emperor Wu sent envoys to notify the various government offices in the capital to execute all the criminals who were imprisoned for the witchcraft incident, regardless of their severity.
