The rules are simple, it's about competing in individual combat strength.
Two fight at a time until the top ten are determined.
Other disciples just need to have a general ranking.
Because only the top ten receive rewards.
The rewards include Cultivation Techniques, Spirit Arts, Spirit Crystals, and Spiritual Weapons.
But the most important is a priority choice right.
This priority choice right is used in the challenge to advance to a Purple-clothed Disciple.
That is to say, the top ten Blue-clothed Disciples qualify to fight the last ten Purple-clothed Disciples, and the victor will be promoted to a Purple-clothed Disciple.
The higher the ranking, the wider the range of choice.
Each Purple-clothed Disciple only has two chances to be challenged.
Thus, there are at most twenty spots available for promotion to a Purple-clothed Disciple.
Aside from the top ten, Cultivators of the fifth level of the Palace Mansion Realm also have the right to challenge.
