'She didn't choose a ninth-grade elixir...'
Wei Wuyin had wanted her to choose a ninth-grade product, because he had long since reached a point of perfection in the lesser grades. It was only ninth-grade products that gave him difficulty, instilling excitement within his heart. Regardless of his disappointment, this was still a clash.
Now, they would test their skill in quality, speed, and success rates. If he triumphed against her in these categories, then he'll know of his skill level.
Qingye Ying was somewhat lost as she saw Wei Wuyin's crestfallen gaze. A strange emotion welled within her heart, uncertain of its origin or meaning. She could only feel that lost sensation.
