The plane landed in Y City, and Lao Yu led Yin Bing to the hotel where his son disappeared. They checked in, and Lao Yu's face began to be heavy again.

Yin Bing understood Lao Yu's mood, he took out the detector that the spirit pupil transmitted to him, and pulled Lao Yu to walk around the hotel first.

Lao Yu pointed to a room on the second floor and said, "My son lived in this room that day, and Zhang Quan was on his left. ”

Yin Bing brought the instrument close to the two rooms, and there was no response. The disappointment on Lao Yu's face had become very obvious, Yin Bing patted Lao Yu's shoulder, "Don't worry!

Walking out of the door of the hotel, Lao Yu said in a dumb voice: "The police said that he took a taxi out of the hotel, because it was night, the camera did not shine on the license plate number! The car disappeared when it went out, I don't know where he went! Where should we find it!"

Yin Bing was talking to Lingtong in his mind at the moment, "Lingtong, can you still check the surveillance video of the hotel five years ago?"

"If it were someone else, there would be no way, but I'm not an ordinary person!" Lingtong said confidently.

"Hey, that's up to you, anyway, even if the hotel has changed computers in the past five years, the police still have a copy in their hands, in short, this matter will be handed over to you!"

"I'll get you a letter in a moment!"

After explaining to Lingtong, Yin Bing said: "Uncle Yu, let's go have dinner first, I have to ask about the details again, and we will try to sort out a direction." ”

Lao Yu was not in the mood to eat, so when he heard Yin Bing say this, he had to follow him to eat first. The two found a small shop, ordered a few dishes casually, and ate indiscriminately.

Yin Bing's idea is very simple, he wants to find clues on the video first, which is also the only source of clues at present. Lao Yu should have never watched that video, and his source of information was the words confided by the police, so now Lao Yu can't help much.

Then there is that the instrument needs to use Lao Yu's blood as the coordinate base point to start searching, if there is no blind search in the direction, it will consume a lot of Lao Yu's blood, Yin Bing saw that Lao Yu was old, and he couldn't bear to do this.

At the dinner table, Yin Bing asked Lao Hu some questions about the case, whether his son went to meet the client, where the client lived, etc. Lao Yu completely answered the questions fluently, obviously he didn't let go of these clues back then, but he found nothing.

The client said he hadn't seen his son at all, and that that night, the client had a perfect alibi, and he was drinking with a lot of people at another drinking party.

Lao Yu said: "I have seen that customer, and when I saw him, I knew that it must not be him! I can't tell the reason, it's intuition, it's definitely not him! It's Zhang Quan!"

"Okay, okay, we know it's Zhang Quan, we have to find the key evidence, we can't let this kid get away with it anymore!"

At this moment, Lingtong's voice sounded in Yin Bing's head, "Okay, I'll transfer it to your laptop!"

Yin Bing immediately took out his mobile phone and pretended to answer the phone, "Hey, what?!You've got it, send me an email?, thank you, buddy, I'll invite you to dinner when I go back!"

Then he hung up the phone and said to Lao Yu excitedly: "Uncle Yu, my friend got me the hotel surveillance that day, have you eaten well, let's go back and see!"

How could Lao Yu be in the mood to eat again, he threw down his rice bowl, raised his legs and walked out. Yin Bing smiled bitterly and settled the bill, and quickly followed Lao Yu.

Lao Yu said a little excitedly at this time: "Xiao Yin, who are you, how can you still get this video, I begged those police many times back then, but they didn't let me watch it!"

"Hehe, I'm just an ordinary freelancer, mainly my friends are very capable, they are very angry when they hear your son's story, they don't want that scum to get away with it, they are all helping. ”

Yin Bing knew that he had to hide his identity even without the instructions of the Spirit Pupil, and he still understood the truth of making a big move, and he didn't want to be the target of everyone.

The place where they ate was not far from the hotel, Lao Yu took a big stride and returned to Yin Bing's room at a trotting speed, urging Yin Bing to turn on the computer quickly.

Yin Bing turned on the computer, and the video popped up, the clarity was not high, but it was still easy to see the characteristics of each person.

The video started when Lao Yu's son Xiao and Zhang Quan checked into the hotel, Yin Bing saw that Xiao Xiao was a young man with medium stature and glasses, Zhang Quan was actually fatter than he is now, and the buttons on his body were about to burst. The two took the room card and went up to the second floor from the elevator together.

The video automatically shifted to the scene captured by the surveillance on the second floor, and the two entered their rooms separately, and before entering the door, Zhang Quan said something to Xiaoxiao, and Xiaoxiao nodded.

Ten minutes later, Zhang Quan came out of his room and knocked on the door, then pushed the door into the room. Yin Bing guessed: What Zhang Quan said to Xiao Xiao before was that he was going to his room to talk about things in a while, and Xiao Xiao nodded in agreement.

Nearly half an hour later, Zhang Quan came out of the smaller room and went back to his room alone and never came out again. After more than an hour, the door to the room opened, and the door was open, and the room was wearing a baseball cap, casual clothes, and no backpack, as if he was going out for a night run.

As soon as the camera switched to the surveillance of the lobby at the door, I saw Xiao calmly walking out of the hotel lobby, taking a car at the gate and getting in the car and leaving.

Yin Bing seemed to be possessed by a spiritual pupil, constantly touching his chin, thinking while watching.

"Uncle Yu, do you see anything in this video?"

After Lao Yu appeared his son in the picture, his lips began to tremble, and he was almost speechless at the moment, he could only shake his head slowly, and after a long time, he said, "I want to watch it again!"

Yin Bing seriously suspected that Lao Yu's mind was no longer on solving the case, and he was completely taking the opportunity to remember his son, but he couldn't stop the old man, so he had to press the replay button, and he also followed it and watched it again, trying to find some clues from it.

Sure enough, Lao Yu just wanted to see his son again, and when it came to the picture of his son, he asked to make the picture bigger, Yin Bing did it completely, and at the same time patted Lao Yu's shoulder and signaled him to mourn.

After reading it for the second time, Lao Yu sat still and didn't speak, Yin Bing thought for a while before saying, "This final scene is a bit awkward!"

"What?" Old Yu's voice was completely hoarse.

"In the end, when Brother Xiao came out, he was wearing casual clothes, and he didn't take anything, and it looked like he was going out for a run, but he took a taxi, which was very discordant!"

"What is discord?"

"Disobedience is abnormal, not in line with common sense!"

"Oh, shouldn't you take a taxi in clothes like this?"

"No, heck, I can't explain it to you, it's kind of weird here. Uncle Yu, do you see anything strange?"

"I didn't find anything strange. I think...... Look at it again!"

Yin Bing couldn't bear to refuse, and clicked on the replay again, This time he didn't wait for Lao Yu's request, as long as it was less than a day to come out, he enlarged the picture, just to let Lao Yu see it more clearly. In fact, even if the surveillance camera of this hotel is magnified, it is not clear, and sometimes the larger it is, the more unclear it is.

Yin Bing called Lingtong: "Old Ling, can you make the picture clearer?"

Lingtong replied to him, "This is already the clearest version I have adjusted, don't you see the clock in the lobby clearly?!"

Yin Bing's mind suddenly swiped something, he jumped up from his seat, jumped in front of the computer, turned the video back to the beginning, and carefully observed frame by frame.
