The world has been invaded by a "weird space", and a copy of Chinese rules and ghost stories has come to reality. Each country randomly selects "national luck representatives" to enter the dungeon. If the representative dies, the country will be punished (national luck declines, weirdness spreads, natural disasters occur). The protagonist is bound to the "National Luck Cultivation System", cracking the rules in the copy to obtain national luck points and strange origins, and at the same time uncovering the mystery of the collapse of the ancient civilization.
