They went into the hospital and met with the female doctor who treated the girl. As Wei Wuxian observed, she was raped repeatedly, and she suffered damage inside since she was in the early stage of pregnancy, yet she was still penetrated by a variety of things which hurt her uterus and in turn she had to undergo emergency hysterectomy to save her life.

"Was the pregnancy the result of the rape?" Wei Wuxian asked Dr. Gu, the female doctor who took care of the girl. He was trying to get his emotion under control from hearing the misfortune that the girl experienced. Thankfully they found her parents, who reported her missing almost a month ago from her school prom. She was still sixteen years old.

"The embryo's around three to four weeks old, and she was reported missing about a month ago, so the timeline matched." Dr. Gu had seen cases like this, and it always broke her heart, seeing the girl's future ended just like that.

"Were there any more cases like this? Rape, underage girls, kidnapping?"

"I have to check with the records, but you do know that I can't give you any more information without a warrant, right?" 

"Yes, I know. We will come back with a warrant, Dr. Gu, meanwhile, do you mind if you check for the records?"

"I will do that." Dr. Gu hated the way the bureaucracy worked, but she could do nothing about it. So, she just hoped that this young woman with the eyes like a blazing sun, would do something about it, she would definitely help as much as she could. "I'm just speaking to myself now, but someone should probably check on the Han's family girl, who had been missing for a month before she was found a month ago in critical condition. Now she was admitted to the Lan's Psych Hospital, which was just on the other side of this hospital." Then she left without saying anything more.

Wei Wuxian was grateful for the help, and he planned to visit the Han's girl later, but first, he had to see about the girl from last night. He then peeked into the girl's room, which was the one that Dr. Gu left just now. The girl's name was Yuanyuan, and she was just celebrating her sixteenth birthday by the time she attended the prom. She was a sweet and naive girl, with not many friends, who went to a prom with a few of her close girlfriends and a boy that she liked. Her parents were already inside and they were weeping the tears of joy, because their daughter was back, alive. Nothing else mattered. They would do anything to make sure that their daughter would be safe and happy from now on.

"Did the police find the boy she went out to prom with?" Wei Wuxian asked Lan Wangji who stood behind him and hugged him tight. He knew that Wei Wuxian was having mixed feelings right now, and he would do anything to comfort him.

"Let's find out."

They entered the precinct at five minutes to eleven, and went straight to Detective Jiang's office. It was not a homicide case, yet, but Detective Jiang was doing them a favor, especially since this was a serial rapist case that caused an uproar because a few weeks ago, a girl of a quite prominent family was found dead. When they autopsied her, it was found out that she was raped and pregnant. Her parents were devastated and buried her rather quickly.

"Detective Jiang, thank you for your time." Lan Wangji shook his hand. "This is Wei Ying, my fiance, and she was the one who found the girl last night." He introduced Wei Wuxian to Detective Jiang, who was baffled by the speed Lan Wangji moved on from Mo Xuanyu. Well, that was fast… but something in the girl's eyes made him think that this one, too, was not any ordinary girl. And she's kinda reminded him of Miss Mo.

"Not at all, Young Master Lan, the Major Crimes has their hands full, so this is a favor for them." Jiang Cheng showed them the chairs. "Please, have a seat."

After they've been seated, Lan Wangji started to ask Detective Jiang about the potential of other victims, which he answered by showing a big stack of folders containing the rape cases that happened just this year alone.

"These are the unsolved rape cases, that had the potential of the same perpetrators. These girls were underage, raped, locked in some secluded place, and then they were released after a month, more or less. Some of them were pregnant, some of them were not. But most of them did not remember anything about the attackers."

"You say most of them. So, someone remembered?" Wei Wuxian browsed the files quickly.

"Some girls from the earlier cases said that there were three of them, who took turns, sometimes together, and all of them wore masks. But the latter ones said they did not remember anything. And there were traces of drugs inside their bodies, flunitrazepam."

"Roofies." 

"Yes. The tests confirmed that they were roofied."

"Lan Zhan." Wei Wuxian showed Lan Wangji a photo of one of the rape victims lower stomach. There was a burn mark in the shape of a circle with some kind of inverted pentagram inside, located just right above on the pubic region.

Lan Wangji took the photo and examined it closely.
"There were a couple of others like that too." Wei Wuxian quickly browsed the photos and took out the photos of five more victims with the exact same burn mark on the pubic region. "Do you know what this is, Detective Jiang?" He showed them to Detective Jiang, who took the photos and examined them. 

"It looked like some kind of cigarette burn? But there's some kind of a motive there… like…" Detective Jiang tried to look more carefully, "pentagram?"

"Inverted pentagram, more accurately." Wei Wuxian told him.

"Jesus, are we dealing with the devil worshippers? This can get ugly fast."

"No, this is where you're wrong, Detective Jiang. Inverted pentagram is not the symbol of devil worshippers, contrary to popular beliefs. It's a symbol of neopaganism." Lan Wangji explained it to Detective Jiang. "If you want to know about neopaganism, just google it, I don't have any time nor patience to explain it to you."

"Lan Zhan…" Wei Wuxian touched his arm softly. "Anyway, Detective Jiang, I think the perps were trying to deceive us by making a falsely known symbol of devil worshipper mark onto the victims." He explained it to the detective. "Because, the real satanism symbol would be more like a goat head inside the inverted triangle, with Hebrew letters at the five points of the pentagram spelling out Leviathan. Don't ask me how I know, I won't bother to explain."
 
These… two people… 
 
"Fine. Let's say they want to divert the investigation toward the innocent devil worshipper, the question now is why? "

"Why not? They were perverted people, who probably have a lot to lose if someone finds out who they really are. But anyway, these five were the latest victims. What if they started to brand the victims because somehow, someone may recognize them? One of the victims, maybe?" Wei Wuxian took notes of all the names of the victims.

"I think we should start with this one. Victim number one." Lan Wangji pointed at the name on top of Wei Wuxian's list. "I have a hunch that she probably knew her assailants."

"Victim number one, Shu Ye, sixteen years old at the time of the assault. Her parents worked as the cook and groundskeeper at the… Jin mansion. What are the odds?" Wei Wuxian looked at the information details. "After the assault, they moved back to their village, and bought a house, a car,  and a land there to work with. Hmm…" he scratched his chin and then looked at Lan Wangji. "How much do you pay for your chef and gardener?"

"I have to ask Xingchen that, but it depends on how long they have worked, and how good their performances were. But my guess? Probably take more than three years to buy all those things, rather than the short time they've been with the Jins." Lan Wangji took the details and showed them to Detective Jiang. "Did the original investigator follow through with his investigation into Jin Zixun? Because, according to this, he closed the case pretty fast and retired early. And now he lived in a forty foot yacht , which he bought right after his retirement. In cash. That would cost him about two million chinese yuan, definitely not pocket change. And Jin Zixun was exonerated of all suspicions."

Jiang Cheng frowned when he saw the details that he missed. The first detective who investigated Shu Ye's case was Detective Ha, already forty five by the time he caught the case, and it turned out to be his last case before his early retirement.

"I think we should pay a visit to Mr. Ha."

"But before that, I would like to see the autopsy report on the dead girl. Was she cremated?" Wei Wuxian asked Jiang Cheng.

"No, she was buried in the family plot. I'll get that autopsy report for you." Jiang Cheng called the morgue to request that specific report. "Shouldn't be too long."
