Huaitan mist and rain, ten years of returning home. He was once the city's forgotten blade, but now he comes in the rain, not to complain about the past, but to settle things. The rivers and lakes are still the same rivers and lakes, but the old friends are now standing on both sides of the river. Business wars, political intrigues, and hidden clues about life experience, every game is a chess game of life and death. He is not in a hurry to win, but he wants everyone to understand who is the real holder of this chessboard. The blood is still not cold, and the old grudges are not settled. This time, he no longer fights for anyone, only to clear his name.
