Cold Front**

The day when the mountains and rivers were shattered, the bloody man's childhood. In 1937, the artillery fire at Marco Polo Bridge tore apart the tranquility of North China. The company commander of the Northwest Army, Chen Feng, was a reckless soldier who had "rather break than bend" engraved in his bones. In the desperate situation where his troops were defeated and his commander was missing, he refused to retreat south. He gathered the remaining soldiers and recruited martyrs, and in the gap between the iron hoofs of the Japanese invaders and the puppet troops, he pulled up a ragged but straight-backed anti-Japanese armed force. Chen Feng fought with a "crazy" energy: Even though he knew it was a dead end, he still wanted to bite off a piece of Japanese flesh! ** He is as cunning as a fox, making good use of the terrain, cleverly setting up ambushes, and using local methods to create a powerful image; he protects his calf deeply and dares to brave mountains and seas of fire to save his brothers; but he is also unruly and regards red tape as nothing. This "wild" team struggled to survive in the tempering of blood and fire, and roared unyieldingly at the invaders in the most primitive way. In a twist of fate, he met Fang Yuan, the political commissar of the Eighth Route Army. This scholar with glasses and firm faith brought new ideas - discipline, organization, and people's war. One is martial and one is civil, one is wild and the other is stable, collisions and frictions are everywhere. Chen Feng thought he was "too lenient", while Fang Yuan worried that he was "too reckless". However, in fighting side by side again and again, in the purgatory of anti-"mopping up", and under the grief and anger of witnessing the massacre of the people, they gradually understood each other: Chen Feng's bloody bravery needed Fang Yuan's steering wheel; Fang Yuan's ideals needed Chen Feng's blade. **Together they interpret the true "Spirit of the Sword" - not only the victory of the brave men who meet on a narrow road, but also the soul of the nation who cares about their family and country, is resourceful and courageous, and never regrets.
