This kind of "melee" also follows "rules" and is divided by "rank".
The weak are the first to be killed.
Sects with lower rankings exit the stage first.
This is a customary tactic from the old days of the Asura battle.
And this clearing follows the "one sword" principle.
Each major sect, led by their prodigies, clears the field and when encountering weaker disciples from lower-ranked sects, they strike with "one sword".
Only one sword.
If the opponent can withstand it, they qualify to stay and continue the fight.
If they can't withstand it, they leave the stage immediately.
This clears out the weak.
It also prevents the strong from engaging in life-and-death struggles too early, allowing the weak to take advantage of the chaos, which is "a farce".
To some extent, this also solidifies each sect's ranking.
Clearing according to established rankings prevents the sword discussion rankings from deviating significantly.
