This rule is quite fair to both parties. If the attacking side finds that they have underestimated their opponent, they can choose to forfeit, surrendering half of their territory and preventing the number of martial artists casualties from reaching a million.
For the defending side, if their strength is insufficient, they can also choose to give up half their territory, and the opponent cannot attack further.
It's a very fair rule, and all the super sects have no objections, so it has continued to this day.
"Since the Eight Desolates Sect wants to cause a million martial artist casualties, they won't reveal their purpose easily. This battle will be a long, grueling conflict, likely lasting several years. What puzzles me is why the old bastard from Yama Hall dares to intervene?"
