He was once the sharp sword of the country, but due to the failure of his mission, he became a useless person swallowed by nightmares, curling up in the shadow of the small town and lingering. Until he was forced to face Ye Qianqian, a stubborn woman who wanted to sell the ancestral Wing Chun martial arts school for a weird security contract. She hates martial arts, and he fears the past. A sweeping cross-border fighting conspiracy tied them together. When the iron hooves of foreign capital crush the dignity of traditional martial arts, and when the deep-buried trauma is about to explode under the spotlight of the arena, the only direction his trembling fists can anchor is her clear and firm eyes. This is not a story about invincibility, this is a redemption legend about how a lost soul rekindled himself in the long night to protect one person, one hotel, and one thought, and set fire to the prairie fire with fists.
