Whether or not there was a misunderstanding, or a reason for their fight, it was no longer important.
On both sides of the battle, each of their totem armors exploded with a dazzling red light on their interface. With the most gorgeous sound and photoelectric effect, their battle intent was instantly stimulated to the limit. Their bodies were crazily stimulated, they released a large amount of adrenaline, dopamine and enkephalin, causing them to fall into a whirlpool of slaughter, unable to extricate themselves.
Perhaps, to the totem warriors, the battle was the only important thing.
As for the reason for the battle and the target of the battle, it was never important in the first place.
