Houchi and Qingmu's children.
Yuan Qi was raised in ancient times. Yuan Qi's birth is very mysterious. Although he is the child of Houchi and Qingmu, he was not born after their wedding. Yuan Qi hatched from an egg, which is the blood fusion of Houchi and Qingmu. Yuan Qi inherited his parents' genes, and he also had a strong power of chaos in his body. Although he was raised by Houchi, he didn't know that he was the son of Houchi.
When Houchi and Qingmu fought with Jiutian Xuanlei, both suffered heavy losses, and they both vomited their own blood. I didn't expect their hearts and blood to gradually merge into an egg. After the egg was hatched, a child broke out of the egg. This child is Yuan Qi and also the child of Houchi and Qingmu.
Yuan Qi's body is full of the blood of two true gods, so there is a powerful force of chaos in his body from birth. Although Yuan Qi was brought up by Houchi, at this time Houchi has recovered her ancient memory, so she doesn't remember having a child. Houchi and Yuanqi get along as brothers and sisters, and neither side knows the blood relationship between the other and themselves.
