Determining the identity of the participants was an indispensable task. In order to ensure that the best resources were given to the geniuses with the greatest potential and they nurtured the most outstanding talents in the Central Continent, the previous school leagues had limited the qualifications of the participants to those below 40 years old and those with strength above the Great Spirit Master level.
All participants had to be students from the academies in the Central Continent. There had once been experts who had colluded with a second-rate academy to participate in such a competition. However, after entering the Demon Spirit Tomb, they were excluded. That academy had also been disqualified from visiting the Demon Spirit Tomb again. All the students of the academy left overnight, and the academy could no longer operate.
