The reason why Su Yu didn't participate in this event was not because he was afraid other players would be unhappy with the rewards he'd receive, but rather, he feared messing up during the event.
Once players enter the event map, the balance of power would dynamically adjust to an identical level, leaving him with no particular advantage.
If a fellow group member lucked out, winning loads of equipment or something as game-changing as the [Bloodline Curse Rune] (which could reduce the opponent's attributes by 50%), it would highly endanger his odds of success.
Being well aware of his consistently bad luck in the game, Su Yu had no interest in joining a luck-based event.
Yet Snow Leopard took a different perspective from Su Yu's.
Snow Leopard believed that with Su Yu's knack for forecasting, he could predict the location of newly emerging monsters, strategically striking early and securing the position of "Gu King".
