In a modern world ruled by the Great Qin Empire with territory spanning twelve star sectors, ordinary high school senior Lu Zhao is conscripted for the 13th Great Crusade. Awakening an Emotion Harvesting System, he gains the ability to copy others' martial arts special techniques. With a talent score of only 61, starting with his sister's Breath of the Hound, he sequentially copies the abilities of Zhou Changsheng, Shen Xianke, and others. Relying on his superior intellect and system cheat, he rises step by step through the rigid military merit hierarchy. Facing fierce competition in the elite class, suppression by noble sciors, and the brutal reality of the battlefield, Lu Zhao has only one goal: come back alive.
