Seventy five years ago, following the example of Jing Ke who assassinated the Emperor of Qin, Chen Zhen of Jingwu School went to Japan to kill the Emperor of Japan but failed. He became a traitor and was ejected from Jingwu School. In 2011, 75 years later, the massive earthquake and devastating tsunami in Japan along with nuclear leakage intensified worries concerning fall of Japan. Therefore, making landfall in China became the ideal for the Black Dragon Society to rebuild itself. In the fall of 2012, when Japanese government played its shameful role in purchasing Diaoyu Islands, secretly sent by the Emperor of Japan, the master of karate- Qiu Ye came to China to look for Chen Zhen but was hunted by the Black Dragon Society. Female doctor of Sports University- Bai Xiao unfortunately fell in love with Qiu Ye and thus was accused of traitor. By deciphering puzzles of stories of Jing Ke 2000 years ago and Jingwu School 100 years ago, it uncovers secrets of the century-old resentment between China and Japan.)
