Wang Zhong's answer seemed pretty obvious. Undoubtedly, as part of the Heavenly Shell Race Faction, his only choice now was to kill Phumetheus. Although Superintendent Erza had asked him to make his own choice, the meaning and encouragement behind it were quite obvious.
Phumetheus was raised as a future leader of the Fire Demon Race and had been promoted as a super genius of their race. Therefore, be it Phumetheus's own potential or his value, both were of great significance to the Fire Demon Race. If he were to be killed, it would be a heavy blow to them. This was the situation that the Heavenly Shell Race would most like to see. And with Superintendent Erza's encouragement just now, everyone could already guess what kind of reward the Heavenly Shell Race would bestow upon Wang Zhong afterward.
