This article is a combination of two fan fictions, the comic "Death's Conspiracy", and the novel "Hell Apartment" (still being updated). The heroine in this article is Yunchi, the heroine in "Death's Conspiracy". If you haven't read these two, I will recommend them here. They are very good comics and novels.
Yunchi's previous life was called Pu Ai, and she lived in the Hell Apartment. When she carried out the fourth blood-letter instruction, neither she nor her boyfriend survived.
In order to fulfill the agreement she made with her friend Liu Yu, she visited Liu Yu in her soul state. By chance, Liu Yu gave birth, and she was actually sucked into him and became Liu Yu's daughter, Yunchi.
After she became the God of Death, and later became the God of Death, she finally remembered what happened in her previous life. She understood the rules of the God of Death, so she didn't understand why such an apartment existed.
She decided to go to that apartment again to get the real answer. What was the purpose of that apartment's existence?
But this time, she met her former boyfriend. For more than 20 years, she never knew that he was still alive!
