Overall, a novel with good ideas but poor character design. After being framed and sentenced to death for murder, the MC- a violent gang boss- traveled to a parallel world to become part of a police investigation team. He is randomly tied to a system, but when catching criminals, he relies on forced plot development (instead of using brains). I do not like the MC's personality (brash and rude like a gangster); in fact, the original police officer (whose body MC transmigrated into) seemed to have a much better personality compared to MC. I was looking forward to this since we don't have good Chinese detective webnovels (most are Japanese like "Shinrei Tantei Yakumo"), but I was disappointed (my rating was already +1 for having the game system, but character development turned out to be too poor).
