In a distant era, there was a pair of young lovers named Yang Mingyi and Chu Xiaoxue. They love each other like glue, but due to fate, they can't be together. Chu Xiaoxue was forced to marry a rich child, while Yang Mingyi endured the pain of heartbreak alone.
At Chu Xiaoxue's wedding, Yang Mingyi couldn't stand to see his beloved with others, so he decided to jump into the river and end his life. However, the moment he jumped into the river, he saw a shining stone, which was a legendary three-life stone.
Yang Mingyi was attracted by the mysterious power of the Sansheng Stone, and his soul was taken to the underworld. In the underworld, he met Lord Yama. Lord Yama told him that his fate was not sealed, and that he could return to the Yang World through the Nai He Bridge, but only on the condition that he make a promise on the Nai He Bridge.
Yang Mingyi agreed to Lord Yama's conditions without hesitation. He made a promise on the Nai He Bridge, that is, he was willing to spend three lives looking for Chu Xiaoxue, and each life would appear in a different identity.
In his first life, Yang Mingyi was reincarnated as a butterfly, and he flew over the mountains and rivers, looking for the traces of Chu Xiaoxue. He danced among the flowers, hoping to attract Chu Xiaoxue's attention. However, fate passed them by, and Chu Xiaoxue didn't recognize him.
In his second life, Yang Mingyi was reincarnated as an ordinary farmer, who worked in the fields, hoping to meet Chu Xiaoxue again. However, fate played tricks on them again, and Chu Xiaoxue did not appear in his life.
In his third life, Yang Mingyi was reincarnated as a wealthy businessman who had wealth and status, but he still felt lonely and empty. He decides to use his wealth to find Chu Xiaoxue. He hired a lot of people to search for traces of Chu Xiaoxue all over the country. Eventually, he found Chu Xiaoxue in a small village.
However, Chu Xiaoxue has grown old, and she is no longer the young and beautiful woman. Yang Mingyi felt heartbroken, but he didn't give up. He decided to spend his life taking care of Chu Xiaoxue and accompanying her for the rest of her life.
At the moment of Chu Xiaoxue's death, Yang Ming felt a palpitation, and he understood that his promise had been fulfilled. He spent three lives looking for Chu Xiaoxue, accompanying her, and loving her. Their love was witnessed on the Sansheng Stone, and their souls also got an eternal home on the Nai He Bridge.
Yang Mingyi and Chu Xiaoxue's love has gone through three lives of hardships, but they have persevered, and with their deep affection and commitment, they have proved the power of love.
