Rex simply refused to avoid this attack as the System suggested.
No matter how much he tried to avoid it, he was an Alpha, he couldn't show weakness when the others were fighting so vigorously, alongside him. He could even feel the excitement the others felt, permeating into his heart.
For them, this moment was pure bliss.
Being able to fight alongside him was definitely a pleasure and also an achievement for them.
Even against the Fifthborn, the others weren't involved directly in the final fight.
But this time, their help was present, helping Rex battle a God.
That alone was enough to make Rex stand his ground and confront Yulthar head-on, but now he also felt the amount of energy, Nivellen was giving him—despite her condition. It reflected how much she wanted him to win this, his entire body was brimming with kingly energy.
Having no authority to help her previous avatar, she bore deep regret and was in pain.
