"Master… I'm done with my potion," Guanin thought that the master didn't hear him the first time as he saw no reaction from him. So, he went closer and stopped harassing William.
"Step back, go to your cauldron and wait," the master noticed him before but decided to ignore him. In his eyes, he knew each second wasted without watching William's performance was a huge loss.
Guanin felt something was off when the master said these words. Yet it was the master, and he was still confident in his victory.
His arrogance took the best of him and at this time he gave William a mocking glance with a harrumph before returning to stand in silence by his cauldron, not even sparing a glance over William or care about watching his actions.
All this happened in front of the disciples. They didn't have any knowledge about the techniques William was using.
