In the year XXXX of the Gregorian calendar, the war with the historical revisionists became increasingly tense.
In order to expand its combat power, the government began to recruit people with strong spiritual powers other than humans to serve as judges. However, because there are many non-human judges with demonic power, in order to avoid unnecessary impact on history, the non-human judges are forbidden to directly intervene in the battle, and can only command the battle from behind the spiritual barrier specially set up by the government. Violators will trigger the lightning system of the time and space teleportation device and will be responsible for any casualties.
