Of course Lan Wangji heard everything, he always had the exceptional hearing, especially this was regarding someone he loved to the extent of sacrificing himself for their wellbeing. But he pretended not to hear, since Wei Wuxian looked like he was about to die from embarrassment. Fitting, since he was still mentally eighteen years old and a virgin. 

Although he was an exceptional hacker, a daredevil, and a potent troublemaker, Lan Wangji was pretty sure that Wei Wuxian did not have any experience at all in romantic relationships. Well, neither did he, but he already had a so-called relationship with the two other bodies of the same person. Alas, he should just wait until Wei Wuxian is ready. He was not some kind of a savage to force his way in, even if it's for the greater good. The cases could wait. He could wait.

Hua Cheng on the other hand, could not stop himself from laughing his ass off from the start of this ridiculous conversation, especially since he was so in tune with his Dianxia. Lately, he became so happy ever since he moved to BingQiu's house just to see his Dianxia every morning and noon, and night, and repeat. And it seemed that Dianxia had started to warm up to him. Although nothing could be said about the duo bodyguards, they were still as vicious as ever. But one thing that Hua Cheng had, was his unlimited patience.

Wei Wuxian was so flustered about this talk about… copulating, he felt so hot all over. It wasn't that he did not want to, he wanted it so much, but until he was good and ready, they should try to solve the case like it was a new one. So, he excused himself and went out to the balcony to find some fresh air, while checking the dark web for information about pedophiles. He should check himself rather than bother Liu Qingge while he was busy with something that Lan Wangji was asking him to do. So, he thought that now was probably the best time to do some hacking, to see what kind of tech that was available in his supposedly five years into the future. That reminded him that he should look at Xiao Hei and upgrade him into a self-learning A.I, just like his Suibian. Ah, he missed his Suibian.
 
He took out his mobile phone from Lan Wangji. It was the latest military encrypted phone, and the best tool to hack the dark web, so he found a comfy couch and started typing. 

Not long after, he already found everything that he could find about Su Ruoyun, which confirmed what Liu Qingge had sent him not a minute ago. Apparently Liu Qingge also bored out of his skull to be able to hack the dark web amidst the crowd inside. Wei Wuxian chuckled and he browsed the information dump on his phone.

Su Ruoyun was a frequent flyer in pedophiles' forum, just as he thought. He made videos, photos, and sold teenage girl's worn underwear at a high price. Wei Wuxian tracked the IP address of the computer that was used to login into his dark web account and hacked it easily, then he turned the camera on.

Lan Wangji was talking and drinking with the motley crew inside. He knew that Wei Wuxian was flustered by all the talk about sex, he let him cool his head down on the balcony, while still kept an eye on him. So when he heard a loud sound of something going down on the balcony, he jumped immediately and tried to see what was going on when Wei Wuxian opened the door to the balcony and walked in the direction of Lan Wangji and showed him his phone.

"Who's this creep?"

Lan Wangji took the phone and saw that it was connected to the live feed of the laptop, which he assumed was Su Ruoyun's.

"This is Su Ruoyun's son, Su Minshan. He was a total jerk who loved nothing but caused trouble with his other two friends, Jin Zixun and Wen Xu. Wait, you don't think…"

"I think this must be connected somehow since the first victim was connected to Jin Zixun, the third with Su Minshan, let's see if any of the victims were connected to Wen Xu." Then he showed the phone to Shen Qingqiu. "Qiuqiu, do you recognize the guy that the boy talked to?" He pointed at the man in a mask that was video-calling Su Minshan.

"I told you I had these nagging feelings as soon as you said pedophiles' case, it was almost identical with the last one you investigated before your… demise." Shen Qingqiu took out his phone as he accessed the Grim Reaper's private database, which was only accessible for the four of them.

"That reminds me to grant access to Lan Zhan and Hua Cheng. I'm sure they can find some use for it." Wei Wuxian typed some long passcodes, and soon after, Lan Wangji and Hua Cheng's military encrypted phone, which were identical to his, vibrated and a single line message appeared. 
 
Access Granted.
 
Then their phones showed them the files on Kingpin.

"Kingpin?" Hua Cheng asked Lan Wangji, whose face was darkened. He remembered Kingpin. That was the last case that Wei Wuxian took before he was killed. 

"Kingpin is the nickname of the leader of this big-shot drug dealer, mostly opium from Golden Triangle, underage slavery, and high-end automotive thefts." Shen Qingqiu explained it to Hua Cheng and Wei Wuxian, who did not remember about Kingpin since he only encountered him when he was twenty, still two years from his mental age. "The guy that the boy talked to? He wore the full golden venetian mask that was only privy to Kingpin's accomplices." 

"If it really was Kingpin, then these cases are more complicated than it looked." Lan Wangji pulled Wei Wuxian close to him. "But don't worry, I'll protect you this time."

"I will ask my... friend to watch the waterway." Hua Cheng nodded at Lan Wangji, the only one who knew about him.

"Ask him to focus on the high sea, they will try to move via international water." Lan Wangji was familiar with Kingpin's train of thoughts since he worked together with Wei Wuxian six month ago, right before that bastard killed Wei Wuxian in front of his eyes. "If only I had this information six months ago." Lan Wangji glared at Wei Wuxian. "Everything would be different."

"Hey, don't look at me now, I don't know why the future me did not give you access to his private network, well, mine… but there must be a reason for him… me, to do that. You know I'm not easy, right?"
 
"If you caught him," Xie Lian suddenly interrupted, "please don't kill him, I have a few grudges to settle first." He smiled. "Especially for killing my Xianxian."

Hua Cheng looked at Xie Lian in a new light. Although Dianxia looked like a harmless puppy, sometimes he said the damnedest thing, just like this, and it caused him to shiver from excitement.

"Anything for you, Dianxia." He smiled at Xie Lian who smiled back at him.

"So, have you hacked the signal from Kingpin's guy?'' Liu Qingge asked Wei Wuxian who went back to do his thing on his phone. That phone from Lan Wangji was crazy. It was more like a mini laptop, so powerful, and it also connected to a device called…"Suibian?" Wei Wuxian looked at Lan Wangji in question.

"Your car. I'll show you later."

"He bounced through nine countries and hundreds of different servers all around the world. Sounds familiar?" Wei Wuxian grinned at the anticipation of catching a bad guy. At least if they got him, they could interrogate him about his plan here. Why here? Was it really a coincidence that The Grim Reaper also transmigrated here?

"He's copying your trick." Liu Qingge answered him. He took out his laptop and started to do his own hacking.

"Qingge, copy all the content of Su Ruoyun's laptop and put a tracker in it, if the boy or anyone contacts Kingpin again, we'll find out."

"Got it. Just use Suibian and put him into search mode, he can keep searching even though you sleep or… do anything else."

Wei Wuxian smacked Liu Qingge's back.
 
"Damn, I lost the connection. Kingpin has gone offline." Wei Wuxian almost threw his phone on the wall, but stopped it at the last second. "I think I need to practice typing with two thumbs more." He sighed and gave his phone to Lan Wangji for safekeeping. "Well, I see your mom is looking like she was about to skin you alive, so I'm gonna go there and have a girl talk with her and Jiang Yanli. She's Jiang Cheng's sister right?"

"Please don't talk about the case with her. Or with mom." Lan Wangji warned him. "They will be scarred for life."

"Then what should I talk about? Knitting? Cooking? I might as well tell you that I don't do knitting. Or cooking. Or girl's stuff. If you want to have second thoughts about me."

"Never. I love you just the way you are." Lan Wangji kissed him and patted his butt lightly. "Go on, do the girl's bonding time. At least fifteen minutes please, before you run away."

"Right. I'm going to start the countdown now. Five minutes you said?"

"Fifteen." Lan Wangji rolled his eyes.

"Five it is." Wei Wuxian grinned at him as he walked… no, sway his butt purposely to tease Lan Wangji.

"Five is enough." Damn that little minx.
 
Then Lan Wangji went back to face Liu Qingge again. 

"Qingge, can you cross reference between the rape victims, and the three people I mentioned? Jin Zixun, Su Minshan, and Wen Xu? Anything that could be the place where they crossed paths."

"K. By the way, I found something about Mo Xiang." Liu Qingge turned his laptop around to face Lan Wangji. "She was caught in the Lan's Tech security cameras at the time of the theft that you mentioned. Both of them."

"What did she do?" Lan Wangji raised his brow. This was surprising.

"She just lurked around the secure area looking suspicious. If I don't know any better, I would suspect her of being the bait for the real thief to do their job."

"What if that's exactly what she did? Bait? Lookout? Did you find her whereabouts right now?"

"Her passport showed that she entered Hokkaido, Japan, about a month ago, right before Mo Xuanyu was killed."
Some patterns suddenly formed in Lan Wangji's mind.
 
This was all connected.
