At the end of the Qing Dynasty and the beginning of the Republic of China, Fang Shiyu, the second son of the "Jingwu Guild Hall" in Jinling, was naughty by nature but extremely talented. At the "Universal Commodities Expo", he witnessed the foreign boxer Charles humiliating the Chinese. He jumped onto the ring in anger, defeated his opponent with clever moves, and became famous in one battle. After that, the martial arts master in the capital provoked the Jinling martial arts community with a challenge from Thunder Tiger. Fang Shiyu stepped forward again and used the Fang family's unique skill of "Thunderbolt Collapse Mountain Hammer" to shatter its golden bell and defend the dignity of the martial arts community.
At the same time, Fang Shiyu received an invitation from the "Red Flower Club", an anti-Qing organization, and went to the "Honghua Pavilion" on the bank of the Qiantang River with his mother and brother to attend the meeting, and was involved in the "anti-Qing and restoration of the Ming" world. At the meeting, Ordo, the son of the prefect of Jinling, led the court forces to provoke, which also led to the shocking conspiracy of the mysterious killer organization "Blood Drops" and the mastermind "Nine Thousand Years Old" behind the scenes - to collude with Western powers and create "biochemical weapons" in an attempt to subvert the country.
Fang Shiyu's long-lost sister Fang Yongchun appears as an undercover "Blood Drop" to reveal the truth of the conspiracy. Everyone formed the "Beijing Anti-traitor Army", went straight to the Forbidden City, and launched the ultimate showdown with the "Nine Thousand Years Old" in the "Lengxiang Palace". Fang Shiyu suddenly realized the true meaning of martial arts during the battle, destroyed "biochemical weapons" with exquisite swordsmanship, helped his sister and everyone in the Red Flower Society eradicate the traitors, and ushered in a turning point in the fate of the nation.
