Blake saw whiteness.
He also saw Blackness.
Blake saw Ryan by his side. Plus, with the way the surrounding area looked like, he realized that they were trapped by his own sword.
Blake understood one thing, any powers higher than the Transcendent rank would instantly destroy his blade... He was not ready to change the future..
Besides, even if he did want to change the future it would not be as easy.
Maybe even the terrifying power of prayer might not be able to shatter it... Maybe, the sword has more mysteries than Blake could imagine.
Blake stared at all the whiteness and he activated the Giant ability.
He immediately unleashed a Crushing punch, but it repelled crashing on him and Ryan.
Judging by the state of the blade, it would be hard to break off it's prison hold.
