Actually, Liu Shuguang spoke very vaguely, but Song Yun understood his meaning. To put it simply, Liu Shuguang was reminding Song Yun that if this person is really yours, and this matter gets exposed, it definitely means someone has targeted you. In that case, seek out the real culprit and don't come to me, I'm just doing a job. If you are really angry, find the people from the Ministry of Public Security.
It's just like when gods fight, humans shouldn't get involved. If this person isn't yours, and this matter gets exposed and Bo Qingfeng bites back at you, it also means someone has their eyes on you. Again, seek out the real culprit and don't take it out on our Criminal Investigation Bureau people.
