Guixu Pavilion: I Fight Monsters in the Underworld Cracks of the City

My sister disappeared for three months, leaving behind a painting and a line of words: "Brother, don't look for me. You can't find me." My name is Song Yu, a programmer, and I live in 302, an old building in Chengzhong Village, Shenzhen. I have been able to see things that others cannot see since I was a child - but I always thought it was my hallucination, until that night, I saw a woman in white in the corridor. She has no face. Later I learned that the building I lived in concealed the deepest secret of the city: the rift in the underworld. And my sister walked into that crack three months ago. Time is different in the cracks than outside. For her, it's been a three-year wait. There is only one way to save her - open the door in 302. But my sister wasn't the only one behind the door. There is also a female ghost who has been trapped for twenty years, a mysterious organization wearing a Nuo opera mask, and things awakening deep in the cracks. My name is Song Yu. I have a pair of yin and yang eyes. What I see is what others should not see.
