Huo Dongjue is Huo Yuanjia's son, and he and Huo Yuanjia's apprentice Chen Zhen are dependent on each other. The two travel around the world, enjoying their grudges. Chen Zhen has always been strict with Huo Dongjue, hoping that he can grow into an upright and promising young man. The Japanese martial artist Sato wants to dominate the Chinese martial arts world. In order to combat Sato's gradually rising power, Chen Zhen decides to rebuild the Jingwu Sect. Sato was very unwilling to suffer the blow, so he kidnapped Huo Dongjue, hoping to get Chen Zhen into committing suicide. After learning that Huo Dongjue had been kidnapped, Chen Zhen was extremely anxious and immediately decided to bravely break into the tiger's den alone. However, there were so many enemies that Chen Zhen was outnumbered, and was eventually killed by Sato's trick. However, before his death, Chen Zhen was so heroic that he greatly weakened the power of Sato's party and promoted the glory of China.
