This was only the primary selection stage, so the Sect Master would not come. He would only let the sect's eldest disciple come to preside over it.
The eldest disciple of the Sect Master took out his Sect Master's token, and 30 arenas appeared on the square.
The head's eldest disciple read out the rules, then used a magic tool to choose a number. The chosen one would go up to the arena to compete. If the person who had chosen a number did not arrive in 15 minutes, it was considered a forfeit.
Dong Xi was at the Qi Refinement stage, so her number would usually be in the 1st to 10th ring.
During the registration, there was a special test of cultivation. The sect would separate the more powerful disciples to avoid meeting them in the first round.
Qi Refinement stage disciples like Dong Xi could be said to be cannon fodder and would not fight to the end.
