One night and an opportunity, seven selected people started a game called the Holy Grail War. Saber (sword class), Lancer (gun class), Archer (bow class), Rider (riding class), Caster (spell class), Assassin (killing class), Berserker (mad class), Ruler (adjudicator). The Holy Grail War includes these 8 classes. Come to the end to get the Holy Grail that can grant any wish.
(Note: It has a human-machine feel, but it is generally good and looks good. Some of the judges may not know that it is to ensure that the Holy Grail War can proceed normally and without interference. The Holy Grail can really grant wishes here, but in what form I don't know)
