The footage that Tou Ge showed Ling Yan and Mu Yuan was a surveillance video, capturing the incident where they were previously attacked by those four strange individuals at the Hongyi Dojo.
When Ling Yan saw the video, he understood that Kai must be angry for the sake of the brother Biao, who passed away at the dojo, from the Phantom Night gang.
This incident, in some way, had something to do with Mu Yuan, and Ling Yan understood why Kai would take his anger out on them.
Ling Yan closed the notebook and looked at Kai: "We are also very sorry about Biaozi's incident. This incident was caused by us. We will cooperate with you to find the murderer behind it. In fact, we already have some clues."
Kai chuckled, his voice full of disdain: "Any clues? Tell me, let me hear what clues you have."
