CompletedZi Zhou was originally a small employee in the villain department. Because he disagreed with the villain's philosophy, and because of his gentle and upright personality, he often caused the plot to collapse. Transferring departments and gaining more freedom was the beginning of his success. Sticking to his principles allowed him to live more freely.
