Military Life: I Took a Leave of Absence to Enlist, and Now I'm a General!

[Military camp + opposing force + System + no fantasy + internally consistent logic] “Shocking! The National Flag Guard has come to poach someone!” “Shocking! Li Zhan takes first place in the all-army Hunter Training Camp!” “Shocking! Li Zhan receives the People's Guardian Medal!” “Shocking! Li Zhan gets his star!” Li Zhan, a sophomore at Kyoto University, longs for military life forged in blood and fire. He resolutely takes a leave of absence to enlist, becoming a brand-new recruit. From then on, heavy artillery thunders, fighter jets soar, and armored formations charge! The Longguo field army is fierce! Forward! Kill! Only sacrifice can inspire greater courage. Who needs to return wrapped in horsehide? You don't need to know me. You don't need to recognize me... The motherland knows me, and these mountains and rivers know me! When I fall, take my rifle! Field army! Kill!!
