In the old Jing Dynasty, evil spirits and monsters ran rampant. The Xuanqing Guard was established to monitor the world, eliminate traitors, punish evil, and support the righteous path. Shen Hao transmigrated to this world and spent four years climbing from an ordinary soldier to a petty officer in the Xuanqing Guard. However, due to his background, further advancement seemed impossible. One day, he discovered a dragon within his body—the ancestor of ten thousand dragons that feeds on the souls and spirits of the living! Every time he kills an enemy, the dragon emerges, tempting him to devour the enemy's soul, demon pill, or evil core, causing his cultivation to rapidly increase. Shen Hao: I'm just solving cases; how did I become invincible?
