Liu Chen's flying knife had directly pierced and killed the murderer, leaving him no opportunity to harm the hostage he was holding.
The reason Liu Chen got close to the murderer was to provoke him into threatening Liu Chen himself, thus redirecting the dagger his way. This was the chance Liu Chen was looking for.
Truth be told, Liu Chen wasn't sure whether the murderer would turn the dagger on him or not,
Liu Chen's sudden action dispelled all previous doubts about him from others, even Zhong Gui was so shocked that he stopped talking.
Soon, the police rushed in and successfully rescued the female hostage.
Liu Chen returned to his original position and glanced at Zhong Gui without saying a word.
Zhong Gui also glanced back at Liu Chen, and deep in his eyes was a hint of wariness. The two patrol guards he had sent to deal with Liu Chen had already reported back that Liu Chen was formidable, and now, he had seen Liu Chen's skills for himself.
