It turned black. In War Poison, Wei Junxuan did blacken, but in the end he returned to the right path. Wei Junxuan lurked in the United Association as an undercover. Facing the double pressure from gangs and police superiors for a long time, he gradually lost himself and finally chose to leave the police force and become a traitor. However, his good brother Cheng Tianhe and Xu did not give up on him, and finally succeeded in pulling him back to the right path. The three men fought side by side again and repelled the enemy together. In this process, although Wei Junxuan was blackened, he was not completely whitewashed. His staff is black and white, but it is gray. He was corroded and sunk by too many temptations, but he still had a bottom line and knew right and wrong. This also adds more complexity and attention to the plot.
