The north wind rises, its howling grows fierce. The embers in Jiangnan have yet to cool, while undercurrents are already stirring in Beiping.
Shen Zhiguang rescued Shen Huaiyi in Jiangnan, only to become entangled in a deeper game of chess. The old Shen family case was not over. The true mastermind, "that person," had finally emerged in the north. Secret files, memories, betrayal, and death all pointed to the same name: Shen Huaijue. The truth about his father's death had been buried layer upon layer, hidden deep beneath the northern snow and wind.
Jiang Huiqin received false information and headed north. An assassination on a train, a fall from a cliff, and a pursuit through a snowy forest: step by step, she was pushed toward the entrance to the secret files. She was the trigger, Zhiguang was the key, and the door was hidden deep beneath the lake. The closer she came to the truth, the more she realized that someone was using her to drive Shen Zhiguang toward the abyss of fate.
Shen Zhiguang chased the wind through the snow, from the train to the cliff, from the snowy forest to the hidden passage. He knew it was a trap, but he had to go in. Because she was in there. Because the Shen family was in there. Because only he could unlock the secret his father had left behind.
The north wind rises, and snow and wind bear down on the city.
The secret files are about to be opened, and the truth is about to emerge.
Shen Zhiguang and Jiang Huiqin are being driven by fate down the same road with no way out.
And "that person" finally steps out of the shadows...
He is the person Shen Huaijue trusted most, and the key to the Shen family's downfall.
The wind howls again, and the game begins anew.
The northern wind will blow away every lie.
Theme: No matter how fierce the wind and snow, the human heart will endure, and the truth will eventually light up the darkness.
