Frontier Inn, Picked up the King of Zhenbei as a Waiter (106 episodes)

Su Qingwan, a transmigrated orphan girl, is divorced by her newly minted third-rank scholar husband. Taking five hundred taels of silver, she travels far to Luomapo on the frontier to open the Guihong Inn. By chance, she rescues Jun Wuxie, the wanted King of Zhenbei who lost an arm, and makes him work at the inn to pay off his debt. Relying on gourmet food and ancient salt-making methods, Su Qingwan amasses wealth and maneuvers through the frontier army, imperial monitors, and northern Di invaders, ultimately joining hands with the soldiers to guard the strategic pass and build a prosperous life in ancient times.
