Qiu Fushun's son Qiu, who was less than one year old, was rescued by the old doctor Qi Daren, and was later adopted and renamed Qiu Yin (Chen Musheng). Twenty years later, it was the last year of the Qing dynasty, and corruption in the Qing dynasty was even worse. The secret of stealing soldiers' money from the ouchi vault has never been exposed. Qiu Yin learned a stunt from Qi Daren, and he also has superb martial arts. He inherited his father's footsteps and sneaked into the capital in cooperation with Qi Daren, determined to rediscover this secret and kill the people.
Qiu Yin took advantage of the medical treatment to break into the imperial treasurer's mansion and use his special status as a doctor to fight Rong.
