Dinia wasn't arrogant, but he let Noah complete his preparations anyway. The cultivator was there to prove that his perfect self could defeat his opponent, so he didn't want to rely on tactics or intelligent approaches. His victory had to be flawless on every field.
Noah understood Dinia. Truth be told, he even liked the cultivator's world. The privileged experts stood on Heaven and Earth's side, but they were entities that had resisted the rulers' control for many years. They deserved his respect.
Of course, that didn't change anything in the battle. Only one of them would survive that clash, and Noah had every intention to come out as the winner.
The ambition released by his companions and the potential that filled the black crystal made the workshop function at an unfathomable speed. Countless six-armed dragons and fiendish figures appeared in his technique's darkness, but the dark matter eventually retreated to gather around his blades.
