The former first-class sergeant of the special operations brigade in the northern theater, 35 years old, died while protecting his comrades during a border anti-terrorism mission. He was reborn as a 22-year-old lazy man with the same name in a mountain village at the foot of the Daxingan Mountains in Northeast China in 1977. The core strengths are only the field survival, combat shooting, terrain analysis, organizational management capabilities and modern outlook of the special forces, without any cheats.
