Lin Shuo, a modern port and shipping entrepreneur, touches the ancient stone carvings at Lotus Peak in Chaoyang, Shantou, and accidentally activates the millennium tide mirror, traveling back to Haimen Haikou Village in the first year of Xiangxing of the Southern Song Dynasty. Relying on his modern mindset, he unites with local righteous men such as Chen Menglong to defuse camp crises, mediate fishing village grievances, and guard coastal defenses. Every time the protagonist makes a move, he loses a part of his own lifespan, calibrating this memory of local loyalty and righteousness. The story adopts a dual narrative of ancient and modern times, artistically adapted from Chaoshan local historical materials, with some plots being fictionalized interpretations.
