That was why William stuck to searching for the grand gatherings of his enemies, even when he didn't find anyone at the previous six spots.
He stood in his place watching the incoming seven dark gold dark masters with a calm look over his face. He wasn't feeling overconfident in killing them, but he was considering how to do it in the least losses possible.

If he let them do what they wanted, they'd end up wasting more than three elixirs just to take these foes down. The thought of losing this battle didn't even flash in his mind at all, and all he thought about was how to better control his spirit power consumption, limit the use of his elixirs to the lowest minimum.
