Brother and sister + fairy + empress, three generations of love
The two of them were immortals from heaven, who came down to earth to experience calamity by chance.
In the first life, he was an adopted child from her family. In the eyes of outsiders, they were brother and sister. They loved each other but could not stay together. And he was her father-killing enemy. I would rather leave before you than watch you disappear from my eyes.
In the second life, the two ascended to the gods and returned to the heaven, retaining the memories of their previous lives. However, because the heaven did not tolerate sentient beings, they had their immortal bones shaved off, their immortal bodies shaved, their immortal memories removed, and they were demoted to the mortal world. They were never allowed to return to heaven again. She fought tooth and nail for him to get the elixir that would preserve his memory. In front of Feixiandai, she said, this time it's you who will chase me, okay?
In the third life, Si Mingxingjun chose a good destiny for them. She was the empress, and he was the general who protected the country. In this life, they went through many hardships and finally achieved perfection, making up for the regrets in the previous life.
