Since the penalized students could afford a high donation fee, they were naturally not short of money. In order to complete the mission earlier, they would basically buy well salt from Yun Chujiu in the end.
Hei Xinjiu quickly made a huge profit. She felt that this self-examination workshop was simply a treasure land of feng shui!
The brine did not cost money, and the firewood did not cost money. As for the free labor of Gouwei Bacao, she only cared about collecting money.
She was not afraid of being exposed, because those students who bought well salt from her would only tell the truth if they were stupid. After all, they were cheating.
Therefore, Hei Xinjiu did not have any psychological burden and replaced the brine in the self-examination workshop with spiritual stones. She happily stuffed them into her storage ring.
This fellow even had a wicked expectation that the more students were punished, the better! Only then could she earn more money.
