What's the matter between Nu Wa and Fuxi?

According to ancient legends, Fuxi and Nuwa are both brother and sister and husband and wife. For example, Custom Yi Tong said, "Nu Wa is Fuxi's sister." "Spring and Autumn Annals" said: "Hua Xu was born with Fuxi as a male and Nuwa as a female." Lu Tong's Poem on Friends with Mayi, a subset of Yuchuan, says: "Nuwa was originally the daughter of Fuxi." All illustrate this problem.

Fuxi and Nuwa were originally brother and sister. Later, in order to save the whole life, they joined together and became husband and wife again. Therefore, the relationship between Nuwa and Fuxi can be described in one sentence, that is, they are both brother and sister and husband and wife.

In myth, about 9000 years ago, a goddess named Hua Xushi visited Razer, only to find that she turned into a snake-headed Raytheon. Soon after I came back, I became pregnant, and this pregnancy lasted for twelve years. Finally gave birth to a pair of twin brothers and sisters, namely Nu Wa and Fuxi.

Later, when brother and sister grew up, a great disaster happened in the world. The sky was crumbling and a terrible black hole appeared. Coupled with the raging rainstorm, a very serious flood disaster has been formed, which has plunged the surrounding areas into chaos and caused countless human casualties.

In the end, with the rescue of two people, Patian killed the black dragon and everything finally returned to normal. However, there were too few people left in the tribe at that time. In order to breed human beings and the world, Fuxi proposed marriage.
