Capítulo 1684: Fake And Real Void Beasts.

Becoming fake Sovereigns is one of the options for titans of law with one regret or another about their concept. It is not the only one. There's also the option to participate in the trial of heaven and use it to gain the assistance of the Will of the realm.

She could have considered the second option, as it wouldn't block her future progress. Unfortunately, the High Heaven Realm is no more, so she cannot gain another Origin for another chance at creating a concept. 

Besides, that wouldn't have solved her problem. She knew what she wanted. She didn't want a weak concept, so she would have done the same thing if given another chance.

So gaining a life crystal is really her only viable option. She didn't get the assistance of the dragon spirit when she was a hatchling because the law of life was weak. That would have solved her problem even before she had it. Unfortunately, she was too weak then.
