FOR EVERY
Unknown to everyone around, the true reason why Alex restrained his aura was because of the looming threat that he felt hanging over his head.
He was well aware of where this threat had come from and because of the trauma it had caused him, Alex was quick to step back and observe.
When Alex released his mighty aura and the moon distorted, he felt his bones vibrate, warning him of possible danger, he could even see vague hands hanging around the clouds of the night sky. Those hands eerily resembled the white hand that grabbed onto him the first time he tried breaking through to the Spirit Transformation realm.
Due to this, Alex instinctively backed away. Now this is not to say that he wasn't strong enough to resist this danger, but he was a bit cowardly towards the challenge this time.
