A normal person could definitely be seen in public.
The greatest possibility would be that Du Li had once done something bad and was hunted by the police!
Judging from how he was staying by Mo Kun's side and helping him with his evil deeds, this speculation by Yu Yuehan might just be correct.
If Du Li was really a fugitive, it would be much easier to get rid of him…
"On the day Bengbeng met with the accident, I remember very clearly that I was the first to be there. When I rushed forward to save her, someone was giving orders to get rid of her as soon as possible. That voice sounded very sinister; even though I did not see what the person looked like, the voice has been stuck in my head ever since. However, this person was not part of the group that was sent to the police station afterward. I have asked Qi Yan about it, and he said that one of them got away. Do you think that the person that got away was Du Li?"
