The one who stopped Rex from activating the "War God Arena" was the old man who had previously made Ye Shuangluo feel a spine-chilling threat.

His identity was Yang Shiqi, a steward for a significant figure among the Titan Gods.

This old man was also one of the referees for the elimination rounds.

It must be said, Yang Shiqi was indeed quite intimidating, and he ordered Rex to stop.
