Special forces soldier Lu Xiao transmigrates to Great Zhou, reduced to a humble youth in Sangzi Village. The original owner was plotted against by green tea Lin Ruoxue, ruining his family, and she even tries to trick him into doing military service for her lover. Lu Xiao exposes the conspiracy to teach Lin Ruoxue a lesson, and comes to know and stay with Liu Xianya, whose background is fraught with hardship, thereby activating the Exquisite Pagoda golden finger, obtaining the Blood-Quenching Pill and the Dragon Shadow Infinite Spear Technique. Wielding the Black Dragon Spear, he resolutely joins the army to guard the northern border, furiously slaying the White Wolf King. Relying on special forces combat skills, he fights against Hu cavalry in infantry combat, raids the enemy camp to behead Hu chieftain Shuji, and shakes Yuyang Commandery with his might.
