A modern-day food delivery rider wakes up in Northern Song Dynasty Bianjing, arriving at Rainbow Bridge on the Bian River with crab roe buns in hand. Watch him use insulated delivery boxes and per-order bamboo tally sticks to turn the marketplace upside down, founding the Swift Delivery Society amid power struggles among the nobility and the flames of the Jingkang Incident. When QR-code patterns on delivery boxes meet Along the River During the Qingming Festival, and quicklime heat meets magnetic compasses, a battle to defend civilization, wielding food as its blade, begins to rewrite the measure of a dynasty's decline. The burn scar on his palm has long since been engraved with a promise that has stayed warm for a thousand years: “Always delivered on time.”
