By chance, they became the "Four King Kongs" and became men among men, but this does not mean that they share a common destiny. Is the military camp a place to settle down or a platform leading to the peak of your career? Is it a competition area that embodies the value of life or a Qiancheng that supports the prosperity of the nation? Living in peace and thinking about danger, survival and life form an equation that cannot be solved completely. This is an idealistic aria. The novel uses the thirty-year growth experience of a certain military training elite "Four King Kong" Cen Lihao, Fan Chenguang and others as clues to describe the painful and slow transformation that is currently taking place within the army - the evolution from tradition to modernity.
