In the ordinary town of Nanyuan Town, there lived a young man named Su Yu. He is thin in stature, but his eyes reveal agility and perseverance. His parents are ordinary mortals who make a living by farming. Although Su Yu has been yearning for immortality since he was a child, he knows that cultivation of immortality is just an unattainable dream for an ordinary young man like himself.
One day, Su Yu went up the mountain to cut firewood as usual. The mountain forest is quiet and deep, and the sun shines through the gaps in the leaves, forming golden beams of light. Suddenly, a snow-white spirit fox flashed in front of him, its tail flashing with a strange light, as if it was guiding Su Yu forward. Su Yu's curiosity aroused and he chased after him without thinking. The spirit fox shuttled freely through the mountains and forests, and it took a lot of effort for Su Yu to keep up. After chasing for an unknown amount of time, the spirit fox stopped in front of a hidden valley, and then turned into a stream of light and disappeared.
