Different difficulties yielded different rewards.
Ye Xiao was strong, so killing the mother spider had been relatively easy for him, resulting in an ordinary reward. Bai Xi was weaker, making her task harder, so her reward was better.
The overarching principle was the game's mechanism of nurturing players and weeding out the weak.
What made Bai Xi curious was why Ye Xiao and his team still hadn't managed to advance to Rank B players. Was it a lack of ability, or had they not met a certain condition? She had asked them before, but they didn't know much either.
They only knew that one could upgrade by passing an advancement trial, and that these trials were incredibly difficult, fraught with danger at every step. Ye Xiao and the others had never experienced an advancement trial because once notified by the game to participate in one, there were only two outcomes: pass or die.
