Through the course of a 40-year time period, Gao Liang and Gu Yi Ye follow different paths in the course of their lives. In 2013, Gao Liang after being transferred to be acting brigade commander came upon a series of issues of falsification and formalism and decided to reform the training methods. Through a series of actual combat training, he managed to train a group of soldiers who can fight well. In a military exercise conducted by the headquarters, Gao Liang persisted in the tradition of actual combat and at the same time, lead his group in breaking the prescribed forms of methods and innovating a new combat method.
