The uncle bent his back and carried a broom to mop the floor diligently in the corridor.

The two security guards fell asleep on the table, and Yan Bei floated on the ceiling like a ghost.

Jingle bells.

A noisy phone ringing woke Yan Bei up, he suddenly got up from the bed, picked up his mobile phone to check, and found that the caller was Bai Yiran.

Yan Bei pressed the answer button and asked vaguely, "Are you dumb?" ”

Bai Yiran: "?? ”

This kid is quite vindictive, and he will scare me back.

Bai Yiran gritted her teeth and said, "Phew! I originally wanted to call you for breakfast, but if you like to eat or not, you will starve to death! ”

"Eat, eat, hehe, I'll come." Yan Bei got up from the bed and glanced at his mobile phone before leaving, it was half past nine in the morning.

Belch......

Are you sure it's breakfast?

In the restaurant, Bai Yiran was unkempt and wore a set of bear pajamas, which looked particularly cute.

She sat at the dining table obediently, pointed to the rice cooker, and asked Yanbei.

"I boiled millet porridge, do you drink it?"

Yan Bei stared at Bai Yiran directly, he didn't expect her unkempt appearance to be so beautiful, he couldn't help but look at it twice, and replied stupidly: "Drink." ”

"Hold it yourself." Bai Yiran pouted and muttered, "Originally, I thought that people were not feeling well, and you would cook porridge for me in the morning, but I didn't expect you to be a big lazy worm who could sleep better than me." ”

Yan Bei scratched his head slightly shyly and apologetically, "I'm really sorry, I was too tired and overslept last night." But sister, I have a major discovery, the problem that has plagued me for so many days has finally been solved, and it is still what I dreamed of. ”

"Huh?" Bai Yiran was a little confused, "You dreamed of it?" Slaying the Dragon King in your dream, do you think you are Wei Zheng. ”

"It's not." Yan Bei shook his head quickly and explained: "Listen to me, haven't I been watching the surveillance these days, and I have checked all the information of the eight security personnel guarding the gate of the vault, and I have not found any problems." ”

"I wondered how I couldn't find any clues. This question has been bothering me these days, until last night, I dreamed that I went to the vault and saw the cleaning uncle mopping the floor in the vault, and it dawned on me. ”

"It turns out that in the surveillance, there has never been a cleaning uncle. We've missed someone, and this cleaning uncle may be the one who stole the diamonds. Otherwise, why did he only delete his footage in the surveillance, right? ”

Bai Yiran put down the small bowl of bone spurs that was as warm as jade, blinked his big curious eyes and asked Yanbei, "You mean, the diamonds in the vault were stolen by Uncle Cleaning?" An old man over sixty years old can open the door of a tightly monitored, heavily coded vault! ”

Yan Bei was confident, "Yes, is there anything impossible about this?" Chen He, who has never learned network technology, can still contact hackers and crack the comic opening screen advertisement, why can't an old man over sixty open the door of the vault? ”

Bai Yiran waved his hand, "I didn't mean that, I mean that the door to the vault is very cumbersome, and it takes two burly men to open it, how did he, a sixty-year-old man, do it?" ”

Yan Bei explained: "Perhaps, he is a member of the Martial Arts Sect, in short, he is not an ordinary old man. After dinner, you ask the HR department to call up his information, and I only need a picture to be able to deduce if he actually stole the diamond. ”

"No problem." Bai Yiran finished drinking porridge, ran to the bedroom and hugged the laptop, the appointment and dismissal information of the personnel department is on the company's official website, she only needs to log in and verify the identity of the president, and she can extract it at will.

Soon the information was sent to Yanbei's mobile phone, according to the information prompt, the cleaning uncle's name is Ren Yuan, sixty-two years old, widowed, once a hotel cleaning supervisor, retired to apply for the cleaning service department of Zhongshan Group.

There is no problem with the information, and Yan Bei is also very clear that there is nothing wrong with this kind of resume, and if you want to know more about Ren Yuan, you must calculate it through the cloud seal.

Yan Bei sat on the sofa, put Ren Yuan's photo on the corner of the table, lit the incense cone, and began to start the cloud seal calculation.

A puff of curling green smoke rose into the air, Yanbei waved his hand to collect the smoke, spread it on the table, and under the random arrangement and combination of smoke, it gradually reflected the fall of Zhonghai City.

With the deduction of Yanbei, the bird's-eye view gradually shrank, and finally settled in an old community at the junction of urban and rural areas.

There are 12 buildings in the community, each with 8 floors, and Ren Yuan lives in 6 buildings with 7 floors, a set of two-bedroom and one-living rooms.

According to the results of his own deduction, Yanbei Kuaiyu explained, "Ren Yuan was widowed three years ago, and after retirement, he was idle and bored at home to meet the call of the country and retire and re-employ." ”

He has been engaged in cleaning work for nearly 30 years, has been in the industry, and has a son, who is too busy with work and rarely sees each other on weekdays. In order to alleviate his son's financial pressure, Ren Yuan will transfer his pension to his son every month. ”

"Financially constrained, suspected of stealing diamonds." Yan Bei shook his head, "No, being suspicious doesn't mean that you will definitely steal, after all, the vault is well guarded." ”

"Oh, that's not right!" Yan Bei sighed, and Bai Yiran, who was sitting next to him staring intently at the picture of the smoke on the desktop, hurriedly asked him.

"What's wrong? Did you confirm that Ren Yuan was the one who stole the diamonds? ”

"Not confirmed." Yan Bei shook his head, his face dazed, "According to the results of the deduction, Ren Yuan hasn't been to work for two months. He has been stuck at home and has never been out of the house. ”

"Huh?" A hint of surprise flashed in Bai Yiran's beautiful eyes, "He didn't go to work, so why did the attendance sheet of the personnel department show that Ren Yuan has been commuting normally." ”

"There must be a secret hidden in this." Yan Bei continued to deduce, "I found it, two months ago, someone knocked Ren Yuan unconscious and pretended to be him to work in the company, this attendance sheet is probably made by someone who pretended to be him." ”

Bai Yiran was even more surprised, "You mean, someone disguised himself as Ren Yuan to come to the company to do cleaning, is this person sick in the brain?" ”

Yan Bei corrected: "Someone pretended to be Ren Yuanlai to steal diamonds from the company's vault. ”

Bai Yiran rolled her eyes, "You're right, then you hurry up and deduce, who is pretending to be Ren Yuan." ”

"I can't deduce it." Yan Bei said helplessly: "With the ancient art ability I have now, there is no way to deduce the fate of another person through one person as a medium. ”

"What then?" A hint of disappointment flashed in Bai Yiran's beautiful eyes, "We can't go to Ren Yuan's house to find out, right?" ”

"You reminded me of that." Yan Bei extinguished the incense cone, and directly got up and went upstairs to change clothes, "Why not, let's go to Ren Yuan's community now." ”

"I'll go, I'll go." Bai Yiran got up and caught up with Yanbei, and the two returned to the upstairs bedroom one after the other.

After washing, I changed into a set of casual clothes, and drove downstairs to Ren Yuan's community.
