After cultivating immortality for 3,000 years, the True Lord Xuanxiao, Shen Changjun, resolutely descends from the mountain and returns to the mortal world to make up for the guilt he feels toward his parents. He finds his descendants, Shen Guofu and Shen Niannian, nearly 200 generations removed, and integrates into the secular world as an ordinary person without official household registration. He works part-time at a bookstore, grows crops, protects the ancient locust tree, and searches for his ancestral home. While fending off attacks from evil cultivators, he also accompanies Shen Niannian as she steadily advances from the first level of Qi Refinement. He rediscovers the former site of Shen Village, restores the ancient locust tree, and personally plants millet. Three thousand years later, he finally steps into the old courtyard. It turns out that the warmth and simple joys of mortal life far surpass the immortal mountains and seas of clouds. Shen Changjun, who had been missing for so long, has finally truly returned home.
