Six days later, at 7 p.m., the Anju Police Station, inside the office of Group 4.

"Oh, Sister Xian, it's really out of ......" Si Rui faced the small mirror to touch up her makeup, and complained to Li Xiaoxian on the other, "If you can ask, you should have asked all of them, right?"

"It stands to reason that if something like film appears in the hands of a patient in a mental hospital, it can be regarded as a relatively special thing, and it should be remembered by others, right?

"However, it's been almost a week, and I've asked more than a hundred people, how can there be no progress at all?"

"If there is no progress, I can only continue to ask!" Li Xiaoxian said, "Group 1 and Group 2, aren't they still looking for those people who have left the mental hospital?

"You say......" Si Rui gestured with his hand, "Wasn't there a shoebox under the bed during the live broadcast? Could it be that the film was originally packed in the shoebox?

"Tut-tut......" Li Xiaoxian smacked her lips, "You don't know yet, do you? Forensic Doctor Zhang has already examined and analyzed everything under the bed, and analyzed the fingerprints and DNA of dozens of people, but most of these fingerprints and DNA cannot be compared!"

"Doing so is tantamount to looking for a needle in a haystack!"

"Oops, it's annoying, it's annoying!" Si Rui rubbed his face angrily, "Who the hell is this Z bandit?"

"Say, are they dead a long time ago?

"Shh......h ......At this time, Zhou Tang at the desk shushed at Si Rui and said, "You be quieter, calm down, calm down!"

"Hmmm......"

Si Rui and Li Xiaoxian looked at each other, but saw Zhou Tang fiddling with a roll of film on his desk.

Before that, he had been fiddling with this roll of film for almost 1 hour!

"Brother Tang, what are you doing?" Si Rui asked curiously, and couldn't help but lean over, "Are you looking at it?"

"Cut," Zhou Tang snorted, held up the film and said, "I'm wondering, the owner of the film, why didn't you move it?"

"Oh?" Zhou Tang's words aroused the curiosity of the second daughter, and Li Xiaoxian also came over.

"Look," Zhou Tang pinched the head of the film, pulled the film hard, and pulled out the negative inside, "Look, if I really want to plate it, then I must be unable to help it, and I want to pull out the negative, right?"

"Oh, yes...... Si Rui said ponderingly, "but what Ma Biao picked up was a film that had never been opened!"

"That's right, because as soon as you open it, the film will be exposed!" Zhou Tang frowned and fell into deep thought again.

"Wait a minute," Li Xiaoxian said, "can we really be sure that no one touched it before that anchor Da Tao pulled out the negatives?"

"What if someone touched it and then screwed the film back?"

"I just checked with Ma Biao's live video, the node where the big pottery was stretched out is exactly the node that can be developed later, unless it is a high degree of coincidence, otherwise, we should be sure that this roll of film has never been opened before!"

"But ......," Si Rui wondered, "what's the use of knowing this?"

"Yes!" Zhou Tang said seriously, "I'm thinking about it too!"

"I'll go," Si Rui took the film in Zhou Tang's hand, "Just for this, you pondered for an hour?"

"Hmm......" However, Li Xiaoxian's train of thought had already been brought up, and he immediately guessed, "This shows that the film has been sealed before, and no one has touched it!?"

"Yes," Zhou Tang nodded, "It was only later because of the relocation that the film was exposed, and it was exposed for a full 5 years......

"Think about it, there are so many patients in the mental hospital, if anyone had taken this film, then I'm afraid all the negatives would have been pulled out and exposed!

"However, the film has not been moved, this ...... And what does that mean?"

"Description...... Hmm......" Li Xiaoxian pondered, "the film was placed in a safe place, and other patients couldn't reach it!"

Or...... Something is a doctor's, put in a doctor's office?

"No, that's not right......," Li Xiaoxian said, "Since the film has not been touched, and it was found from the ward, there is a greater probability that it is still a patient!"

"Speaking of that ward," Zhou Tang asked, "what did the hospital say?"

"That ward is a general ward," replied Si Rui, "there are 8 beds in the ward, and there are so many people who have been there!"

"At present, Kong Wang is still following up on this line, who are the people who have been checking that hospital bed?"

"Oops," Li Xiaoxian sighed and said, "How do I feel that eighty percent of the owner of the film has been hung up?"

"Is this film his relic?"

"No, it's not okay to guess like this," Zhou Tang said as he played with the film, "We still have to find a breakthrough!"

"Hehe, it's easier said than done," Si Rui said stupidly, "Film is the biggest breakthrough, but it's a pity that only Liu Shuangshuang has no robbers on it!"

Well......

mentioned the photos on those films, Zhou Tang also felt disappointed.

Previously, they had tried to find the location of the photograph by analyzing the details on the photo, or by using some reflections to find clues about the photographer.

However, although the shooting was not professional, the photos were taken without leakage, and there was nothing behind Liu Shuangshuang except for a wall with a white cloth.

Originally, Chu Juntao also wanted to use the dilation of Liu Shuangshuang's pupils to capture the photographer's information, but because the photo was not taken well and the light source was not used, he couldn't see anything......

Breakthrough, breakthrough......

Where will this breakthrough be?

This time, Zhou Tang finally felt that he had encountered a really difficult case, and in this case, his deceptive skills were useless.

For now, they don't seem to have any other way but to question the people in the psychiatric hospitals......

It wasn't until now that Zhou Tang understood why the original detective Yao Beixin, as well as the later task force, didn't finish this case!

Just thinking of this, Zhou Tang's phone suddenly rang.

After answering, Zhou Tang felt a little surprised, the call was from the section chief Wang Jing!

"Zhou Tang," Wang Jing asked very directly, "I'm waiting for you in the No. 2 private room of Yiren Western Restaurant, I know you haven't eaten, come and eat together!"

"Hmm...... This ...... Zhou Tang was even more surprised, "You mean...... You're going to invite me to dinner?"

"Yes," Wang Jing said naturally, "Room 2 is a double room, do you understand?"

"Oh......" Zhou Tang's comprehension ability is not bad, and he immediately nodded and said, "Okay, I'll be there soon!"

After hanging up the phone, Si Rui grinned and asked, "Did someone invite you to dinner?"

"Yes," Zhou Tang didn't hide it, and said directly, "It's your future team leader's wife who invited me to dinner, are you satisfied?"
