Wen Yi, an immortal who has lived for three hundred years, intended to descend from the mountains and let his departed beloved, Su Yuan’er, see a peaceful and prosperous age through his eyes. Instead, a group of food-loving officials from the Zhenguan court dragged him into the bustle of everyday life. He went from a recluse by the stove to the pillar that steadied the golden age of Zhenguan. He warms hearts with good food, brings order to the world with his strategies, and illuminates humanity with his immortality. Through one farewell and reunion after another, he finally comes to understand the ultimate meaning of immortality: not eternal life, but an eternal legacy.
