"Shut up and be quiet!"

Tie Jiaolong turned his eyes suddenly, and his gaze, which was as cold as a sword, instantly made the room quiet again.

But in Tie Jiaolong's heart, he is also the same as the three of them.

As a top soldier of the Xuefeng Special Operations Brigade, she has seen many high-end geniuses, similar to this kind of face recognition, but she has never seen anyone who can have such powerful image processing capabilities, except for machines, she can't think of a second description.

Suddenly, she remembered what Xu Lian had said a few minutes earlier.

"That means the ones you see aren't geniuses. ”

Xu Lian, what kind of person are you!

Staring at the back in front of him, Tie Jiaolong fell into deep thought.

A few minutes later.

Xu Lian suddenly let out a sigh of relief.

He lowered his head and gently rubbed the Qingming acupoint between his nose and eyes to relieve long-term eye fatigue.

"It's over?"

Tie Jiaolong still couldn't believe it, from just now to now, Xu Lian has selected a total of two pictures, what the lens can shoot is a passage more than ten meters long, in the middle of the passage is a bathroom, and at the end, it is the R&D department of Shengming Pharmaceutical.

Looking at those three pictures, Tie Jiaolong felt that they were normal, and there was nothing unusual at all.

Xu Lian nodded, and patiently explained: "Shengming Pharmaceutical's security work is okay, there are no loopholes on the whole, especially outside the R&D department, if you want to enter the R&D department under the premise of avoiding monitoring, there are only two possibilities, first, grasp the control of the monitoring equipment, delete the record or cover it with a fake picture, but you said before that you didn't find any abnormalities in these monitoring, which means that the other party did not use this method." ”

"Yes, I've checked many times, and all of these surveillances are normal, and no one has tampered with them. Tie Jiaolong said with great certainty.

"So, there's only the second possibility. ”

Xu Lian paused, his pupils shrunk, "Insider." ”

As soon as the words fell, Tie Jiaolong reacted extremely violently: "This is impossible, I have investigated everyone in the R&D department, and I specially borrowed the latest polygraph from the military, if you don't have professional training, you can't escape the polygraph test." ”

"What if this insider is a fake?"

"It's still not possible. ”

Tie Jiaolong shook his head again, "I just said, I investigated everyone in the R&D department, and three of them took leave, but none of them showed up in the monitoring on the day of leave, unless, someone used some time gap to fake ...... while they were working."

As he spoke, Tie Jiaolong's voice suddenly weakened, and his eyes flashed with an incredible light.

She slowly turned her gaze to the second capture.

It's the picture outside the bathroom.

"That's right, the mystery is in this bathroom. Xu Lian said, "Fatty, play the first picture." ”

"Okay. ”

In the first picture, a man in a suit and leather shoes can be seen entering the bathroom, and not long after, in the direction of the R&D department, there happens to be a R&D personnel walking towards the camera, after entering the bathroom, he left after about two minutes, and in the third minute, the man in the suit and leather shoes also left.

Now, let's look at the second picture. ”

Similar to the picture just now, there was also a person who was the first to enter the bathroom, but he was not the man in the suit in the first picture, but wearing a shirt, and his appearance and hairstyle had changed greatly.

After a while, the R&D personnel returned to the R&D department, and within a minute, they covered their lower abdomen again and went into the toilet.

Tie Jiaolong watched these two videos three times, but finally shook his head and said, "What's the mystery here?"

A smile crossed the corner of his mouth, and Xu Lian said unhurriedly: "The man in the suit in the first picture and the man in the shirt in the second picture are actually the same person. ”

"What!"

Tie Jiaolong's pupils shook suddenly, and then he compared the two pictures again, and after three more times, he revealed a hint of abruptness, "When the two of them walk, the swing of the left arm is slightly greater than that of the right arm, only left-handers will have such characteristics, but left-handers are not unusual, just by virtue of this, how can you be sure that this is a person?"

Xu Lian smiled and nodded: "Just looking at this, it can indeed be explained as a coincidence, but if you look at the second picture, the R&D personnel who left the bathroom for the first time, pay attention to the position of his left arm." ”

"Actually, you're left-handed?"

Tie Jiaolong's face changed suddenly, because before this, looking at the arm swinging habits of the R&D personnel, he did not echo the characteristics of left-handers.

There is only one possibility.

At this time, the R&D personnel are simply fake, but the thief who is proficient in disguise is disguised, and the real R&D personnel are probably still in the bathroom!

"If you want to complete a perfect theft, you need to meet three conditions, intelligence, key, alibi, in addition to these two scenes, the thief has also disguised other identities and easily entered the company, in order to collect intelligence, and the content in the first picture is to make the key, the research and development personnel who unfortunately appeared in the bathroom, is his key, physiognomy and fingerprint collection, it was completed in that time period. Xu Lian didn't sell anything more, but explained directly.

"Brother Lian, let me interject a sentence, how is the thief sure that this R&D personnel will appear in the bathroom on time in the second picture?"

"It's simple. ”

Xu Lian said, "Now that you know his appearance, it is easy to track him outside the company, and then poison his food or water source, it is a breeze." ”

"Laxatives are too difficult to grasp, isn't this thief afraid that the R&D personnel will pull it up a few times, and he will collapse directly or be cured by taking medicine, and he won't appear in the bathroom at all?"

"The development of laxatives has long been not what you imagined. ”

Tie Jiaolong Yin said in a cold voice, "As far as I know, there are several laxatives in this world, which can accurately control the onset time, and will recover on their own without treatment. ”

Xu Lian didn't say anything, but frowned slightly, staring at the man in the suit in the picture.

There were some things that he didn't say.

The murderer who killed Ye Bing was also a left-handed man!

It's the same person!
