Eleena remained silent for a while, before resolutely lifting her head and fixing her gaze on Xi Wei. "Then I am willing to become a believer of the God of Games!"
"Belief isn't something to only be spoken by mouth. Close your eyes and envision His name in your mind, and feel His power with your heart," he said solemnly.
"O Master of Games, grant us new life!"
