Wei Changying, daughter of the richest man, disguised herself as a man and joined the army in the northern border to avoid a bestowed marriage. Relying on max-level martial arts and modern tactics, she inflicted dimensional strikes all the way, subjugated rebellious soldiers to form the "Trap-Breaking Camp", and engaged in hilarious Shura field tug-of-war with the dark-bellied prime minister Pei Wujiu and imperial prince Zhao Xi. Facing the pressure of 50,000 northern barbarian troops, Wei Changying reversed a desperate situation with clever strategies, captured the enemy general alive, and rallied the down-and-out strategist and commoners to build an iron defense line outside the Great Wall. After the great victory, court forces returned to the capital, and Wei Changying's female identity almost got exposed in extreme probings. Heavy snow sealed the mountains, an isolated army stayed behind, and the eerie green beast pupils lighting up in the wind and snow foretold that a cruel survival crisis was about to descend.
