"Qingcheng, you didn't notice anything strange? It seems like I'm not too useless." Tang Ling had suffered so many blows today that he began to doubt himself.

"Put it in again, and put it in each patient again." Gu Qingcheng analyzed that the person behind it sent Yuan Yu's cell phone through the patient. The fact that he didn't find any abnormalities just now does not prove that there is no problem at all.

It's very likely that she overlooked something, it's very likely that she overlooked a certain detail. Sometimes one detail can change a lot of things.

She had previously thought that with the intelligence of the person behind her, he would most likely give the person who helped him carry his things a suitable reason, making the person who helped him carry his things think it was a normal thing.

If that were the case, there couldn't be anything strange in the expression of the person who helped him carry his things.

"Okay." Tang Ling didn't ask any more questions or say anything more, but followed Gu Qingcheng's wishes and turned the video back again.

Gu Qingcheng still stared at the picture without blinking and continued to observe, but this time Gu Qingcheng was not only observing the patient's expression, this time she paid attention to all the details.

Tang Ling helped her adjust the video, skipping the time when the patient entered Yuan Yu's office, and only showed the scenes of the patient entering and exiting Yuan Yu's office.

Tang Ling has watched it several times, so he is very skilled in adjusting the video.

"Stop." Gu Qingcheng shouted quickly when he saw a patient walking out of Yuan Yu's office.

The moment Gu Qingcheng shouted stop, Tang Ling stopped the surveillance screen.

"What's wrong? Is there something wrong? This person looks normal." Tang Ling looked at the person on the screen carefully and didn't find anything strange.

"He didn't have a mobile phone in his hand when he came out, but when he went in, he was holding a mobile phone in his hand." What Gu Qingcheng paid attention to was not the man's expression. That expression was indeed natural and nothing strange.

"Really?" Tang Ling was stunned for a moment, and then quickly turned back the video. Sure enough, he saw that when the patient entered, he was holding a mobile phone in his left hand.

"Have you put it in your pocket? He is wearing a coat. It is normal for him to be in this situation, and he is not the only one. Why do you think there is something wrong with him alone?" It's not that Tang Ling doesn't believe Gu Qingcheng,

Rather, it analyzes some things objectively.

Tang Ling brought up the scene of the patient walking out of Yuan Yu's office: "The left side of his clothes is slightly lower than the right side, so his mobile phone is probably put in his pocket."

Gu Qingcheng did not explain, but brought up a picture of the patient walking towards Yuan Yu's office. In the video, the man's body was facing them sideways, but the hem of his coat could still be clearly seen.

"When he entered, the left corner of his clothes was slightly lower than the right. It was the same as when he came out of Yuan Yu's office."

"So, if his cell phone is in his pocket, then when he goes in, his cell phone is already in his pocket, and when he comes out, there is nothing in his jacket pocket."

"It would have been more obvious if he had put his cell phone in his pants pocket when he came out, but judging from the surveillance, it was obvious not, so the cell phone in his hand was left in Yuan Yu's office."

Tang Ling looked at it carefully, analyzed it, and then narrowed his eyes slightly: "Qingcheng, you are right, he did not take out the mobile phone he was holding."

"This is the mobile phone fragment we just found in Yuan Yu's office. Let's see if it is made of the same material as the mobile phone that person held." Jing Lanchen took out the mobile phone fragment and placed it in front of the surveillance camera.

"You can't tell by looking at it this way, and the person was holding a mobile phone in his hand. The phone is not big, so you can hardly see anything in his hand."

"We can't even see what the phone looks like, how can we tell what material it is made of?" Tang Ling glanced at the fragmented phone, and then looked at the phone held by the patient on the surveillance camera. He thought it was

Impossible things.

"The materials should be the same, but we can find a professional trace analyst to confirm." Gu Qingcheng came to a conclusion directly, and in a positive tone.

"Qingcheng, you can see this? How can you see this?" Tang Ling was shocked, although he had always known that his Qingcheng was very powerful.

But he didn't expect that Qingcheng, his family, was so powerful that he could actually tell the material of the phone just from the surveillance camera that couldn't tell what the phone looked like at all?

"Qingcheng, you are really amazing. I admire you more and more."

"Check the surveillance in other parts of the hospital to see who this patient has come into contact with elsewhere in the hospital."

"That person asked the patient to help bring the mobile phone to Yuan Yu, and he did not make the patient suspicious. He must have had contact with the patient, and there must have been conversations." Gu Qingcheng turned his eyes and glanced at Tang Ling.

Tang Ling's tone was a bit exaggerated. Now that we have this clue, let's follow this clue to investigate.

"Okay, I'll check right away." Tang Ling had already invited the other people in the monitoring room out, and now there were only three of them in the monitoring room, making it very convenient to check.

This time Tang Ling just found the video with the patient who gave him the mobile phone. As long as there was a video of this patient, Tang Ling would not let it go.

Through surveillance video, they found that the patient took the mobile phone out of his pocket after going to the third floor.

"Look, when he went upstairs, the man had already given him his mobile phone." Tang Ling paused when the patient took out his mobile phone: "Check the previous video, you should find something."

Tang Ling's voice was a little more excited at this moment. He had been searching for a long time and found nothing, but now he finally found something.

Tang Ling continued to watch the video, checking everything from the time the patient entered the hospital, from the time the patient registered, to the time the patient went upstairs into Yuan Yu's office, but found nothing.

After this patient entered the hospital, he had no contact with anyone else except when registering, let alone talked to anyone else.

"It seems that the person didn't give him the phone in the hospital. He was really cunning and cautious." Tang Ling found nothing in the end, and his face became visibly gloomy.

"Find this person first." Gu Qingcheng's eyes narrowed slightly. Since he didn't find the person who gave the patient the mobile phone, he would find the patient first.
