University graduate Zhang Yong couldn't find a job, so he relied on his martial arts skills in the university's martial arts team to work as a security assistant in a private company. The company's copper mine located deep in the mountains encountered serious problems. The company sent a vice president to investigate and deal with it, but even lost his life. For this reason, the chairman of the board appointed Zhang Yong to investigate and deal with it himself. Zhang Yong came to the copper mine, and the financial director sent a beautiful woman to warmly receive him. Starting from this beautiful reception woman, Zhang Yong followed the clues and uncovered the truth about the long-term substandard production of the copper mine.
