Two-year-old Princess Jinyang accidentally opens a space-time channel, stumbling headfirst into a modern young man's rented apartment. Steamed buns, electric fans, and cartoons—fresh and wonderful goods are carried over one by one to the Datang, turning deep palace days into a daily routine of carefree joy. Li Shimin exclaims in awe at the fan as a celestial magical treasure, while Empress Zhangsun eats with her eyes and brows relaxed in delight. The soft and adorable little dumpling shuttles between the two realms, feeding the whole family on one side while clinging to her older brother and acting spoiled, filling the air with sweet and soothing healing warmth.
