Azief at that same time also had derived all the Laws and he also exploded with power.
A titanic figure also appears with the same face as Azief. Azief had summoned his Law Avatar and the Law Avatar he is using is his Universal Law Avatar
By now, the world is already translucent and Amara and Azief fight no longer affects Arial world. Instead, they are now basically in the starry skies.
All the while, time is regressing backward.
All of this happened in the span of a few second from Amara putting her finger down to her becoming a titanic form. It is also just a fraction of a moment when Azief summons his Law Avatar.
Azief saw Amara put her finger down and he knew Amara is about to attack.
The moment she put her finger down, the last defense of this Earth from turning into a void is released. And that is why Azief also summons his Law Avatar and the Law Avatar he summons is the one that is most suitable to fight against Amara at this moment.
The Universal Law Avatar.
