Lu Li pushed his dead target into the water and immediately turned around to leave. He didn't even bother with the two other potential targets that he suspected to be players.
In this game, while you inspected others, others were also inspecting you. While Lu Li was chatting up the old man, he had the image of an NPC, but as soon as he killed someone, he became suspicious.
Sometimes, what exposed a player would not be his actions, but his greed instead.
Lu Li blended into the crowd and quickly disappeared from this area.
Although he would have other chances to kill in a similar setting, that would expose him too much. Once he was caught by another NPC or players, he would be in trouble.
