“[Ding! Today's sign-in reward: Four Seasons Medicinal Food and Wellness Guide.]” I stare at the scroll of sheepskin that has suddenly appeared in my palm. Smelling the mold drifting through the mud hut, I finally believe it: I, a third-year medical graduate student, have transmigrated into Su Mingxi, the daughter of the poorest herb farmer on the Qin Empire's frontier. My little brother is huddled in a pile of straw, gnawing on the last half of a sweet potato. The System panel flickers before my eyes: “Survival objective: Keep a family of four fed. Reward: plans for a basic plow and harrow.” I grit my teeth and dig out my modern nutrition notes. I make a warming porridge with wild ginseng and millet, but at the village entrance, a bloodied general stops me. He lifts his helmet, revealing a scar at the corner of his eye like a knife. “Can this porridge save my eight hundred frostbitten soldiers?” I smile. “It can, but you'll have to pay with military merit. I want to make sure no one on this frontier ever goes hungry again.” From one bowl of porridge to a field of crops, from an alliance of convenience to him placing his tiger tally in my hands: “Mingxi, I'll protect this empire, and I'll protect you.” See how a modern medical student uses the System to turn a “herb farmer's daughter” into the Qin Empire's greatest virtuous wife!
