He wasn't afraid of either Gaden or Adam gracing the competition stage for the 2nd duel. However, this was different from the match against Bierlia Academy. Wanting to destroy their opponent in the dueling phase was a task nigh impossible to complete. They will undoubtedly head into the group battle phase this match. Therefore, it would be the best case scenario if they were able to maintain Grai in peak fighting condition for the group battle.
This was why Wang Zhong wanted to take the risk and send Colby as their vanguard. If his gamble had succeeded, this would result in the group battle being somewhat more relaxed. If he loses the best, Tianjing would still be able to put up a fight. Under such thoughts, there was almost no difference in sending Grai up in the previous match or the incoming one. In all, Tianjing still had a chance left.
