This is a carefully planned chess game. The four evil spirits are the chess pieces, Xuanji Castle is the chessboard, and the person behind the scenes is the real chess player. Ma Peng, the ghost sword, is calm and decisive, but he cannot escape his fate; he has a masterful hand in the sky, and he is full of opportunities, but he is also in trouble; Wang Jie, the secret arrow, is cold and ruthless, but eventually encounters a powerful enemy; Poisonous flower, Liu Mei, is charming, but she is plotted against. They thought they were performing a mission, but they didn't know that they had already become part of someone else's plan. When the truth was revealed, they discovered that their biggest enemies were not each other, but the invisible hand hidden in the darkness. In this game-within-a-game, game-within-a-game contest, who can have the last laugh?
