Who can give me a background story of the sound of zero tattoo?

Jiushijia is an ancient family. Like others, they are eager to live a stable and peaceful life. Birth, old age, illness and death are eternal natural laws, and so are long-term parents. However, parting with relatives will also bring endless pain and sorrow to the living, and the death of lovers will also make people feel endless desolation, meeting the deceased in their dreams and thinking a lot. Meeting in a dream can comfort the living, but parents are beginning to find that some people never wake up after meeting the dead in their dreams. There is no other reason, because I am obsessed with the dead, so I left with the dead. The living meet the dead in their dreams, and driven by strong thoughts, they follow the dead to the underworld and never come back. This will not only lead to the death of the living, but also make the death between people more serious. Gradually, these entanglements will turn into resentment and pain, which will accumulate slowly between life and death, leading to its overflow into the world. The boundary between life and death will be confused. Legend has it that in an ancient shrine somewhere, people can see their dead relatives and lovers, and be guided to the deepest part of the shrine by strong ideas, thus reaching the underworld. The living will fall asleep in reality and disappear for no reason. And this disappearance is called "hiding". The mansion of Nine Lions Palace is located on the cliff of the tomb. Elegance is the entrance to the underworld and the starting point of the afterlife. The deceased reached the underworld through here. Because of this, Jiushijia chose the "Witch", turning the pain into "Hiragi" and carving it on the "Tattoo Witch" in the form of tattoo, so that the Tattoo Witch can bear the pain of others losing their loved ones and lovers. That is, the "soul-stabbing ceremony". The selected tattoo witch will turn the thoughts of others into her own body, bear the thoughts of others for her relatives and lovers, and experience the sadness of others in endless sleep (here, sleeping is equivalent to death). To purify the swelling resentment and pain and sorrow on the way to the grave, and let Yin and Yang get calm. The dragon family, handed down from generation to generation, kept a balance with the other world in the ceremony. At the end of the last ceremony, a girl named Rain Sound from Jiushi family came to the ceremony with a tattooed witch's lover. Before she died, the tattooed witch saw the master of IX A kill a person in front of her, which led to the mysterious disappearance of the urban legend. As long as she misses the dead, she will be taken to the dream world by the tattooed witch to meet the dead, and eventually she will die in the dream world and turn to ashes. In the plot, the three protagonists feel pity for missing a car accident. Crimson misses her brother who left zero zero; In order to save my niece, my sister in Zero Butterfly (the official ending in Zero Butterfly is that my sister killed my sister to complete the ceremony, and my sister became a red butterfly because she missed her sister; I was taken into a dream world by a tattoo witch ~! That's probably it ~!
