Having transmigrated into the world of cultivation, Li Qingshan was judged at eighteen to have no spiritual roots, cutting him off from the immortal path. Heartbroken, he retired to Peach Blossom Village, married, and had children, a hundred years flashing by in the blink of an eye. On his hundredth birthday, cultivators from the Chunqiu Sect came down the mountain to select disciples. Erya, a young girl in the village, tested positive for superior spiritual roots and begged the immortal to give Li Qingshan a try as well. To everyone's surprise, the light of the spiritual testing stone soared to the heavens—he turned out to be a one-in-a-million heavenly spiritual root! Yet, at a hundred years old, his vital energy was decaying, and everyone thought it was far too late. But Li Qingshan refused to give up. Seizing this belated immortal affinity, he set off with the others toward the immortal sect, beginning the cultivation journey belonging to a hundred-year-old old man.
