The cases have made some breakthroughs compared to the previous three seasons, especially the first episode chose to climb the snow mountain as the background. In terms of plot development, it will focus on the love-hate entanglement within the team. If you are not tired of the idea that the high-IQ justice team will never fall and good will never be defeated, you can continue to follow the show. Original by Yanji Qinqing.
