In the twenty-sixth year of the Republic of China, war broke out everywhere, and the enemy invaders trampled the mountains and rivers with iron hoofs. She is an inheritor of Chinese martial arts hidden in the market. Her Xingyiquan is as strong as thunder, her Baguazhang is as agile as the wind, and her hard skills are hidden under a gentle appearance. In order to protect her country, she took off her civilian clothes, sneaked into the intelligence whirlpool in enemy-occupied areas, and transformed into an unknown agent walking on the tip of a knife.
Dealing with Japanese spies, Wang puppet traitors and military spies, she used Chinese martial arts as a blade to quietly avert murderous intentions - killing pursuers with her bare hands in dark alleys, deciphering traps in secret rooms by listening and using her strength to deliver secret messages at cocktail parties. Every move is a combination of skill and clumsiness, and every step is fraught with danger.
The intelligence network is intricate and complex, and it is difficult to distinguish between true and false in people's minds. She has to beware of the enemy's overt and covert attacks, as well as internal suspicions and temptations. The old city with blue bricks and black tiles hides secret contact points, the neon-lit dance halls are full of informants, and the abandoned factories hide weapons arsenals. Using her flesh and blood as a shield and her unique martial arts skills as a spear, she split the fog, uncovered traitors, and delivered key intelligence to help the frontline soldiers in the turbulent espionage chess game.
The righteousness of the family and the country is hidden in the light of the sword, and the national integrity is demonstrated in the fist fight. When national martial arts meets espionage, when tenderness turns into strength, she walks her own iron-blooded path in the years of war, guarding the land under her feet and the faith in her heart with silent actions.
