He did not want Unit 701 to suddenly appear in Hong Kong in pursuit of the gang leader. Shi SIR and the police were at a loss for a while. Seeing that his friends were in danger, Xu Xi stepped forward and became a black knight. Black Xia infuriated Xiong Ju (long Gang), the head of Unit 701, and sent Xu Xi's old lover Ruolan to persuade him to obey. Xu Xi flatly refused, resulting in the death of all colleagues in the library except Tracy (Karen Mok). In order to protect Tracy, Xu Xi took a tough attitude to take her away as a black knight-errant again, and was rejected by Tracy who did not know that the black knight-errant was his favorite. Later, in the process of confrontation with Xiong Ju and others, Xu Xi gradually found the emotion he wanted from Tracy.
