A family is brought together by blood, especially the Blood Flower family, which has strange abilities. In order to have enough source blood, every Kao of the Blood Flower family will collect source blood on a large scale around the world after the birth. After all, a large number of tribesmen with source blood split apart in the Qing Dynasty. Only seed blood can become the next Kao. The thing about the Blood-Drip Flower family is strange. The Kao Kings of all generations have been women, because only women can inherit seed blood, and men can only inherit original blood. The blood-dropping family is judged based on the position of the blood-dropping flower growing on the body at birth. The blood-dropping flower grows in the heart, and the source blood grows there. The closer the blood is to the thighs and heart, the purer the blood.
The dense modern technology of the Blood Blossom Family is wrapped up in an era of slash-and-burn farming. The people there lived a life completely different from that of people today, without any interference from the outside world. They slowly drove on the historical track and completed their evolution. In this huge family where modern technology and ancient technology coexist, the place separated is the Flower Garden. The Flower Garden is a place that completely belongs to an ancient civilization, but it is undeniable that there is modern technology in it.
