In Jiangcheng, on Ting Tang Road, stood a pale high school girl looking lost and frightened in an adult store named "Peak of Happiness." "Full service is nine thousand nine, and an initial investigation requires a deposit of one thousand," I said, cigarette dangling from my lips, as I sized up the girl. Under my gaze, the girl seemed very uncomfortable. "I only have seventy on me. Can I give you the rest when I have the money?" she asked. "Seventy it is. Leave the money on the table, and you can go. I'll give you a reply in three days." "Are you... a scammer?" The girl was half doubtful, her palm sweating and soaking the seventy yuan. "I take others' requests as my own duty. Being real, efficient, honest, and confidential is the principle of our business. Your earlier words questioned my professional ethics." I snatched the money from the girl's hand and waved her off. At this point, many might misunderstand me, thinking I'm a scoundrel bullying minors and abducting young girls. In fact, everything I do is to help her. My name is Gao Jian, and I am the owner of this adult goods store. Of course, being a store owner is just a disguise; my true identity is a private detective. Missing persons, corpse searches, corporate espionage, fraud investigations, extramarital affairs investigations, and all kinds of non-litigation case assistance are all handled by our firm. Returning to the main topic, the girl who came seeking help is named Xia Qingzhi, a high school student in our city. The reason she appeared here is also due to an incredible event. "My brother, Xia Chi, disappeared a week ago, and I suspect he has been murdered." The girl looked anxious and frightened as soon as she entered the door. "You should report a criminal case to the police." High school students don't have much money; I just glanced at her and lost interest. "It's no use reporting to the police. I've tried everything. No one remembers my brother's existence, including the household registration investigation. He seems to have disappeared from the world. All traces have been erased." "Are you saying that memories of your brother only exist in your mind?" The girl didn't seem to be lying, and that was the most terrifying part. "Yes, everyone has forgotten my brother, only I remember..." I lit a cigarette and took a deep breath. If what the girl said is true, there are only two possibilities: supernatural events or the girl suffers from severe schizophrenia, with her body hiding a twisted personality of her brother. "Did your brother exhibit any unusual behavior before he disappeared?" At this point, I needed to follow her lead to gather more clues; I wasn't in a hurry. "The night before he disappeared, my brother was invited to participate in an interview for a live streaming platform, and then he never came back." The girl took out a very ordinary-looking card from her pocket, crumpled and worn, similar to the small ads for drain repairs and fake medicine sales on roadside railings. "Do you want to become a star admired by millions? Want to have the worship of billions of fans?" "Become a signed anchor at the Inferno Showroom, open your own live streaming room." "As long as you have courage, talent, and time." "You can turn all your dreams into reality from the comfort of your home!" "Inferno Showroom, what a unique name." I studied the card repeatedly, becoming more suspicious that this was a prank by a mischievous child. I decided to hold off on criticizing the company name and looked at the back of the card. The interview time for this live streaming platform was from 12 midnight to 3 a.m., at 44 Dark Street, Room 444 on the underground 4th floor. This sequence of time and location numbers didn't seem to be intended for a normal person. "Do you also think I'm making this up?" The girl's reaction was on the brink of despair; I could see the loss and fear in her eyes.
