Tian Yin'er defied all opinions to become the crown prince of the Celestial Clan and wanted to marry his sister Tian Jin'er, but was opposed by the Emperor of Heaven and his stepmother, the Queen.
Tian Yin'er showed his strength by defeating the demons and monsters, but still could not save himself and Jin'er's fate.
In order to save Tian Yin'er, Jin'er went to the stage of thousands of reincarnations with a desperate heart. In exchange, Tian Yin'er was finally released from the seal.
When Tian Yin'er arrived, Tian Jin'er's soul had already scattered and landed in the world. Tian Yin'er jumped off the stage of reincarnation with a sad and desperate heart. Although she also arrived in the mortal world, she also lost her memory. When she met Fan Wushuang again, who had Jin'er's soul fragment, her memory was finally restored. Tian Yin'er searched everywhere for Jin'er's soul fragment.
In the end, Fan Wushuang regained his memory and became Jin'er. The two experienced thousands of reincarnations, but their love still defeated fate and finally stayed together.
