Although Xu Zhenyu was rather thrilled to have shaken Si Yiyan off and even prevented him from seeing Wen Xinya, he was not exactly in a good mood. In fact, he felt terrible.
He had met Si Yiyan twice before and on both occasions, Si Yiyan exuded a threatening dominance which made him feel rather terrified. In the past, he used to think that Si Yiyan was a mysterious and powerful man who delved into the triads. He even warned Wen Xinya not to get too close to him.
He had also once felt fortunate about that because he believed that Wen Xinya would not fall for a man like him.
After Wen Xinya got rescued by the mysterious man, Si Yiyan, Xu Zhenyu found out that Si Yiyan was extremely powerful and that he was even associated with the military. Si Yiyan then colluded with the higher authorities of the military and shortchanged him. Ever since then, he knew that Si Yiyan was not one to be trifled with.
