The Old Era, Global World - [Pan-Asian]
This is a world with an advanced level of technology, diverse systems, and abundant resources.
Although people here can pursue system development, because they don't need to worry much about material life, they always have a tremendous spiritual pursuit.
Ultimately, a unique form of duel entertainment evolved here.
Duel arenas were built all over the world, and even at the world's center, a supreme duel area was created for entertainment.
Participants are subject to strict restrictions,
they must be ordinary individuals without a system, maintaining the most primitive and direct conflict.
Those ordinary people who cannot open a system, or those alien beings captured during the world's expansion, as long as they have no system, they are sent to the duel arena.
Anyone can place a bet, and the winner must slaughter the loser, there are no draws, no mercy.
