On a vast, boundless continent ruled by gods and demons, the genius cultivator Gou Dan yearns passionately for a higher realm. Armed with a mountain of cultivation resources, he resolutely sets out on a perilous journey to experience the mortal world. The wheels of fate turn quietly, and through a twist of chance, he arrives on Earth. Hoping to experience every facet of mortal life, Gou Dan seals away his cultivation and memories. But fate has other plans: he ends up inhabiting a newborn baby.
The baby is adopted by the kindhearted, simple Gou Xiong couple, who give him the same name, Gou Dan. Sadly, when he grows up, his intelligence remains at the level of an eight-year-old child. Yet he has a heart of pure goodness, and lives a simple, peaceful life in the mountains with the Gou Xiong couple.
Forty years pass in the blink of an eye. Then an unexpected lightning strike roars like fate itself, restoring Gou Dan's memories of his previous life. His cultivation, however, has vanished like a kite with its string cut, and he must start over from scratch. But Gou Dan refuses to lose heart. An undaunted fire burns in his eyes, and he decides to begin with the most ordinary work of all: farming. Drawing on the knowledge and wisdom he accumulated in his previous life, he leads the Gou Xiong couple and the villagers around them through every obstacle, improving their lives. Under his guidance, the family flourishes and grows stronger.
Even as he farms, Gou Dan never stops cultivating. Every drop of sweat embodies his perseverance. At last, he once again takes his place among the mighty, becoming someone others can only look up to.
Now Gou Dan returns to the God-Demon Continent, bearing the glory of a thriving family. The once-genius cultivator has come back. This time, with his family at his side, he will write a stirring legend of their own on this land of opportunity and challenge.
