"Haha, in fact, there is nothing to say, Mr. Wu, you are just playing a simple trick. Qiao Tianyu shook his head with a smile and then explained.

"When Mr. Wu met me yesterday morning, he had been looking at his watch, as if he was in a hurry, but in fact, Mr. Wu deliberately showed it to me at that time, just to let me guess that you were in a hurry to catch a flight. ”

"Later, after I analyzed that Mr. Wu, you are likely to be the big boss behind the four major conglomerates in Southeast Asia, I asked Brother Sanchez to ask you to meet, but I didn't want you to disappear, so my attention was naturally attracted to the airport. ”

Speaking of this, Qiao Tianyu picked up the briefcase placed on the tea table and took out the photo of Wu Minghao when he boarded the plane at the airport that the KGB had intercepted.

"Later, with the help of KGB agents, I got this photo of you when you boarded the plane, and at first I really thought you were going to Norway, but the more I looked at this picture, the more I felt that something was wrong, but I couldn't tell what was wrong. ”

"It wasn't until I went through customs clearance in the British Virgin Islands that I saw the ID photo on my passport that I suddenly realized that something was wrong with this photo!"

"What's wrong?" Wu Minghao and Michelle both came over and stared at the photo for a long time, but they didn't find anything wrong.

"Mr. Wu, look at this photo of you at the boarding gate of the airport, is it particularly like we were taking ID photos, posing and waiting for the photographer to take them?" Qiao Tianyu asked with a smile.

"Forehead ......"

Wu Minghao and Michelle looked at the photo again, but it was not anything, in this photo, Wu Minghao raised his head and looked ahead, with an extremely standard smile on his face, which was completely a posture of taking ID photos.

"This photo is indeed taken a little too right, but what does that mean?" At this moment, even Wu Minghao couldn't get Qiao Tianyu's point.

"Haha, Mr. Wu, you should know that the CCTV camera at the boarding gate of the British Virgin Islands airport is on the edge of the gate door, and ordinary people will not even look at it, let alone use the camera to take ID photos. Qiao Tianyu explained with a smile.

"Let me guess how you were in your mind when you took this picture, were you particularly worried that the CCTV cameras at the gate wouldn't be able to capture your picture, so you did your best to pose, so you took this picture for me, right?"

"Hahaha, Qiao Tianyu is really Qiao Tianyu, I didn't expect you to not even let go of such a little detail, it's really amazing!" Wu Minghao gave Qiao Tianyu a thumbs up.

"No, no, Joe, you still haven't made it clear!" Michelle on the side shook her head like a rattle again.

"Even if Mr. Wu's photo was taken for you on purpose, it doesn't mean that Mr. Wu didn't board the plane, does it?"

"Haha, yes, Tianyu, how should you explain this?" Wu Minghao also smiled and agreed.

"In fact, after discovering the problem with this photo at that time, I already expected that this time Mr. Wu deliberately took this photo to confuse my audio-visual, and he definitely did not go to Northern Europe. Qiao Tianyu then explained.

So I revisited the photo and found a new problem. Saying that, Qiao Tianyu pointed to the window behind Wu Minghao in the photo, "This is it!"

"What does it mean here?" Wu Minghao and Michelle looked at each other again, saying that the location Qiao Tianyu was referring to was just an ordinary window in the airport waiting room, and there was nothing special about it.

"Oh, Joe, you are not annoying, you like to sell Guanzi! What is the problem, you can say it quickly!" Michelle glanced at Qiao Tianyu impatiently.

Seeing that Michelle couldn't wait, Qiao Tianyu finally stopped selling Guanzi and pointed out the problem.

"Haha, Mr. Wu, you should know that there have been tropical cyclones circling around the British Virgin Islands since the afternoon before yesterday, so the British Virgin Islands has been stormy and the weather conditions are very bad these days. ”

"That's why most of the ferries and flights in and out of the BVI have been cancelled these days, and there are only a few regular departures a day, right?"

"Yes, what's wrong with that?" Wu Minghao still didn't get Qiao Tianyu's point.

"Haha, here's the problem!" Qiao Tianyu nodded with a smile, and pointed to the window behind Wu Minghao in the photo again with his hand, explaining.

"Yesterday, the British Virgin Islands was covered in dark clouds, and there was a black oppression everywhere, but in this photo, the sun was shining and white clouds were shining outside the window behind Mr. Wu. ”

"It's clear that this photo wasn't taken yesterday, am I right, Mr. Wu?"

"Clever! It's so smart! Hahaha......" Wu Minghao smiled and nodded, agreeing with Qiao Tianyu's statement.

"It wasn't taken yesterday, no, this photo was obviously taken from the CCTV video at the BVI airport, there shouldn't be anything wrong with the surveillance video, how could it not have been taken yesterday?" asked Michelle, scratching her head even more puzzled.

"Haha, this one is even simpler!" Qiao Tianyu explained with a smile.

"Airport CCTV video is a relatively independent surveillance system, because CCTV video data cannot be uploaded to the cloud for storage, so all airport CCTV video will be saved in the video tape for archiving. ”

"Because there are many airport surveillance cameras, there are too many video materials that need to be accessed, and the storage space of the videotape is relatively limited, so a large airport generally needs to change the videotape every hour to be able to save all the surveillance footage. ”

So Mr. Wu only needs to go to the airport gate in advance to step on the video, and then take out a copy of the videotape at that time at the airport, modify the monitoring date with technical means, and then replace yesterday's videotape. ”

"So, the tape that the KGB agents got from the British Virgin Islands airport yesterday was actually a videotape from the airport a few days ago, am I right, Mr. Wu?"

"Haha, that's the case!" Wu Minghao affirmed Qiao Tianyu's statement.

"I'll go, that's what happened!" Michelle finally understood, and nodded vigorously.

"Joe, I understand what you just said about the videotape, but what the hell did you just say about saving in the cloud?

"Uh......" Qiao Tianyu couldn't help scratching his head when he heard it, and accidentally said something out of his mouth.

Cloud storage is a high-tech that will only become popular after 20 years, and it is indeed not something that people in this era can understand.
