A brief introduction to the story of the disappearing bullet

During the Republic of China, a bizarre murder case occurred in the largest arsenal in China, and the workers were killed by "ghost bullets"-no bullets were found at the crime scene. For a time, doubts kept gathering and people were worried. This case is the first mystery in the Republic of China. Guo Zhui (played by Nicholas Tse), a hot-blooded detective who is bent on doing harm to the people, can't tolerate the corrupt atmosphere in the police station and joins hands with Lao Lu to investigate this bizarre murder case. Therefore, the case was investigated by Song Donglu (played by Liu Qingyun), a government policeman in charge of file management in the police station. Lao Dao is a civilian. He is thoughtful and has a unique way to solve difficult cases. The female prisoner at the beginning maps how the lark at the end manipulated Guo Zhui and Wang Hai to shoot without bullets, and how to make the bullets disappear after penetrating the body. Lao Lu and Guo Zhui have done various researches on guns and bullets, including firing salt bullets and ice bullets at pigs, but they have no satisfactory results. With the in-depth investigation of the case, the two detectives discovered the horrible murder chamber and the bizarre bomb-making device, which made the experienced old road stunned. Just when the truth of "Ghost Bullets Killing People" came out, Lao Dao, Guo Zhui and Xiaowu were killed one after another. The policeman Xiaowu (played by Jing Boran) was killed when he shot Lao Dao, and Guo Zhui escaped.

The deadline for closing the case is approaching. Little lark (played by Yang Mi), a fortune-telling girl, inadvertently revealed the shocking secret of "Ghost Bullet". They don't know whether this "shocking secret" is a trap or a clue to solve the case, but they swear to fight with their lives! The case finally came to light, but Guo Zhui and Lao Dao found that their respective destinies had been teased mercilessly, and there was only one choice before them.
