"I will take the role of referee so that you can fight with the sole goal of killing your enemy!"
A solemn expression appeared in the geniuses when they heard the words of the Emptiness Thearch. None of them were truly worried that they could kill their opponent as Ezequiel's words only meant they could attack with killing intent without a worry as he could save them in the last second, allowing battles where they could go all out.
What bothered them was that they could be disqualified during the first round, not because they were too weak but because their opponents were too strong.
Take Zaphirox, for example. The Eldar was among the top six in terms of battle strength but could not have a chance to fight for a position among the top five if he were to have an extremely powerful opponent like Noah or Beelzebub.
