Rui had made up his mind on what he needed to do before heading for Kiriket Continent.
He needed to help Amare grow stronger and consolidate her strength on the way to Kiriket so that her probability of survival. He also needed to create anti-Shenlong techniques with the Forge of Creation, with the intelligence that he had gotten from the Whisperer and the data that he himself had collected from the Dragon Emperor.
He also intended to use the Eye of Prophecy to understand how the battle could unfold and what the futures were where he would lose the battle, and understand the conditions that he needed to satisfy to draw out a victory.
His approach was him at his very strongest. Rui was strong even normally, but when he prepared for an opponent specifically, his effective combat power rose greatly, making him even stronger than normal against that one opponent.
He approached the battle with serious humility, caution, and a plan.
