There were many restrictions on the number of participants. There were strict selection rules.
Apart from the two champions, Jiang Chen and Great Emperor Shura, the other three candidates each had to have two followers and a personal disciple. Moreover, the personal disciple had to be of the younger generation. Pill King Lu Feng and Pill King Bu, whom Jiang Chen had taken in, were both of the older generation and couldn't participate in the battle.
In reality, there were many restrictions on Sacred Peafowl Mountain and the Shura Retreat.
Therefore, according to the rules, Great Emperor Peerless was only Jiang Chen's outside friend. Although Jiang Chen had invited him to help out, he wasn't a member of Sacred Peafowl Mountain. It was against the rules for him to request to fight.
Therefore, while his offer surprised everyone, it also made their hearts race. However, when they thought about it carefully, they felt that it was impossible.
