In 1898, in late Qing China, the "Six Gentlemen" were arrested after the failure of the Reform Movement of 1898. Huo Yuanjia was shocked when he heard the news. Infected by the patriotic enthusiasm of the "Six Gentlemen", Huo Yuanjia wanted to do his best to rescue Tan Sitong with the legendary "Big Knife Wang Wu", but he didn't want to be rejected by Tan Sitong. The last farewell with Tan Sitong in prison made Huo Yuanjia deeply influenced by Tan Sitong's Datong thought, and began to have a sense of family and country, and wanted to devote himself to the torrent of history. Understanding Tan Sitong's awe-inspiring desire to alert the world with blood, Huo Yuanjia was heartbroken, but he could only watch the hero die for his country. Because of Tan Sitong's death, he was misunderstood by his sworn brother Big Knife Wang Wu and suffered a broken relationship. Soon after, Big Knife Wang Wu was killed by a traitor and his body was separated. Huo Yuanjia learned the news and went to collect the body of his sworn brother overnight. Although he let Wang Wu keep the body intact, it brought disaster to the Huo family, causing the death of all the male members of the Huo family. A year later, Huo Yuanjia, who lived in seclusion in Cangzhou, went out to escort the enemy, but he didn't expect to fall into the trap of his enemies again. After going through untold hardships, he cleared himself of the connection, but he was disheartened, so he decided to go south to Shanghai. Huo Yuanjia's Jingwu Sect quickly established a foothold in Shanghai, and Huo Yuanjia's fame grew. This made the Japanese, who had already listed the invasion of China as a national policy, very dissatisfied. Faced with the provocation of the Japanese, Huo Yuanjia went into battle despite his illness. In the final contest with the Japanese, he fought wits and courage, and finally defeated the Japanese conspiracy with his extraordinary courage.
