For better or for worse, Lord Zhou was the involved party in the case. If he looked into it carefully, he would discover Ning Furong's loopholes no matter how cautiously she had done it.
In the imperial court, some ministers opposed Ming Shu's decision. But being a fatuous and self-indulgent ruler, Ming Shu persisted and asked Lord Zhou to prove himself innocent.
Lord Zhou had been an official for decades and had ability and connections. Thus he soon managed to trace the case to someone, yet the clues didn't go anywhere since then, and under interrogation, that person admitted he had planned the whole thing.
The case was solved inexplicably like this.
Lord Zhou was restored to his official post.
