Tick, tick, tick, tick.

The clock is ticking.

The police were divided into two ways, and the criminal investigation team gathered people to come to the cold storage and began to study the method of cracking the secret room. This group of people is inclined to believe that the two suspects in the cold storage are not likely to commit crimes, and focus on the methods of the attackers.

On the other side, Liu Zhongwei, a rescued security guard, and Zhang Jianhong, the owner of a fish shop, were not released. After the hospital confirmed that he was in good health, he continued to be supervised as a suspect. Zhu Ansheng's footprint hypothesis raised major doubts about the two people's confessions, and the police officer fought for a further breakthrough in the interrogation room.

In despair, when the hands of the clock quietly turned, the investigation on both sides was equally fruitless.

The method of the double chamber could not be cracked, and the two suspects could not remember anything.

At one o'clock in the morning, Xia Liang received a call from Zhu Ansheng and drove to the vicinity of Tianhe District University of Technology, where there is a Shahe Children's Welfare Institute, separated by two streets from the staff residential area of the welfare home. It is the residence of Zhu Ansheng and the location of the "Ansheng Office".

Zhu Ansheng has been waiting at the gate of the community for a long time. Xia Liang stopped the car and saw that he was holding two sets of thick down jackets and a plastic bag in his hands. The down jacket was covered with dust.

Xia Liang rolled down the window. Zhu Ansheng said:

"I'll drive."

Xia Liang looked at him for a while: "Brother-in-law, do you have a driver's license?" ”

Zhu Ansheng was silent for a while: "Don't ask." ”

"You can't drive without a license."

"My driver's license has been revoked a long time ago."

"Then you can't drive."

"It's early in the morning, and there will be no police."

"Brother-in-law, I'm a policeman."

"Then what's the use of my brother-in-law?"

Xia Liang looked at him seriously, and followed him step by step: "Brother-in-law, it's not okay to know the law and break the law." ”

Zhu Ansheng sat in the co-pilot with an unhappy face, watching the scenery regress outside the window.

Xia Liang put the steering wheel, glanced at him, and smiled bitterly in his heart.

"Brother-in-law, what are you going to do in the cold storage?"

"Something needs to be verified."

Xia Liang was silent for a while, and said sullenly: "I still think it's not good for us to sneak in like this, right?" This is not in accordance with the Force's regulations......"

Zhu Ansheng turned his head and looked at him with interest:

"But here you are."

Xia Liang stopped talking.

He wanted to know the truth. If Zhu Ansheng can't, then no one can.

The white Accord drove into the Huangsha seafood market. The two got out of the car and walked straight into the alley. Zhu Ansheng crossed the blockade line left by the police force, tore off the blockade tape attached to the cold storage door, put it into the bag in his hand, and vigorously pulled the door open.

He motioned for Xia Liang to go in, and Xia Liang went in, turning around and looking for the switch of the cold storage on the wall.

The incandescent lamp flickered, illuminating the entire cold storage, and the next moment, he heard a "pop", and the cold storage suddenly became dark.

The hum of the chiller also came to an abrupt halt.

Xu was psychological, in the dark, he could feel the chill invading his body. He hurriedly looked at the door, and could only see Zhu Ansheng's shadow, and he was also walking towards the door.

"Brother-in-law, did you pull the electric switch?"

Zhu Ansheng said "um", and said calmly, "Don't step on the footprints on the ground", walked into the cold storage, turned around and closed the door.

The light that came in from outside the door was swallowed up. Xia Liang's heart chuckled.

With a "snap", the flickering firelight lit up in the darkness. The flame of the windproof lighter reflected Zhu Ansheng's pale face:

"Put your clothes on."

Xia Liang hurriedly took the down jacket that was thrown over. Follow Zhu Ansheng around the footprints on the ground and walk to the depths of the cold storage.

The two stopped in the middle. Zhu Ansheng put on a down jacket, found a place without footprints and sat down, fumbled in the bag for a while, and took out a ...... Ashtray.

There are also pipes, tobacco, matches, and 20,000 mAh power banks.

Xia Liang thought that the bag contained important tools for investigating the scene, but it turned out to be just these things. Zhu Ansheng's tone was so leisurely that he seemed to have come over for vacation:

"Sit down, it should be a long time coming."

Xia Liang hugged his body and squatted down, feeling a little uneasy.

"Brother-in-law, what are we waiting for?"

"Wait for the cold storage to melt."

When Xia Liang heard this, his spirits perked up, and he vaguely felt that he had touched some key.

Zhu Ansheng continued:

"It takes a lot of effort to measure the time when the ground starts to flood after the power outage in this cold storage. The most direct way is to turn off the power switch directly and actually test it once. But the police force will not do this, because when the power is turned off, everything in the cold storage will be damp, which is likely to cover up some key clues and even destroy the crime scene. So, we can only come secretly. ”

Xia Liang said worriedly: "Then if we destroy the scene of the crime tonight, wouldn't it be a big deal?" ”

Zhu Ansheng looked at him as if he was looking at a fool:

"Wouldn't it be nice if you sat still and didn't move?"

Xia Liang was speechless for a while. He kind of understood what Zhu Ansheng was doing with cigarettes and power banks.

He had leisurely taken out his mobile phone to kill time, and took a puff of cigarette from time to time, Xia Liang's mobile phone fell on the car, and he could only sigh at his uncle.

Holding his shoulders and trembling for a while, he couldn't help but lean towards Zhu Ansheng.

It was boring to sit stupidly, and he couldn't move around. The cold storage was eerily quiet. If a claustrophobic person is locked in, I am afraid that within half an hour, he will go completely crazy.

Xia Liang pressed the horror in his heart and urged himself to think in order to divert his attention. He thought that the three of them were locked up in the same place at that time, and it was natural for him to panic. There was no eye to see, the only light was the faint light leaking from the crack in the opposite door.

His body was getting colder and colder, and he couldn't think calmly. Immediately, he felt that if he was the one who was locked up here at that time, he would definitely remember this experience for the rest of his life.

Xia Liang was stunned and straightened up:

"Brother-in-law, I suddenly thought of it!"

"Huh?"

He was very excited: "You say, if you lock that security guard and the boss in again, can you make them recall more details?" ”

Zhu Ansheng didn't speak, and after a while, he calmly said "um":

"That's a good idea."

"Brother-in-law?" Xia Liang raised his head, a little surprised: "Why are you so cold?" Is there anything wrong with this idea? ”

Zhu Ansheng turned his head and glanced at him meaningfully:

"Nothing. Remember to tell Lao Xing about this idea tomorrow. Some things need to be done as soon as possible, and if nothing else, the police should be busy soon. ”

Xia Liang felt a little negative feeling of disappointed expectations, was silent for a while, and asked:

"Brother-in-law, what do you think of this case? Can't you tell me? ”

Zhu Ansheng slid the phone screen, absent-mindedly:

"It's nothing to tell you. Some things can already be deduced. ”

"What's the matter?"

Zhu Ansheng said lightly:

"Remember when I accidentally knocked over a plastic box today?"

Xia Liang had an impression, and he reacted: "You did it on purpose, right?" ”

Zhu Ansheng nodded: "When I knocked over the box, it caused a lot of noise. Even people who are already in a deep sleep will definitely wake up. Have you ever paid attention to the height of the shelves? It's about a little over two meters. The door of the cold storage is only 1.8 meters, and when you put the shelf against the door and put the plastic box on it, you will never find a plastic box on your head from the outside view. ”

Xia Liang nodded and agreed: "So, this absolute secret room should be established?" ”

Zhu Ansheng shook his head and narrowed his eyes slightly:

"The murder weapon at the scene has been confirmed to be a brick on the ground. Assuming that the deceased was attacked after Liu Zhongwei and Zhang Jianhong fell asleep, the body was not far from the two, there was no trace of being dragged and moved, and the sound of bricks hitting the skull was not small, the effect of chloroform on the two people had passed, and they were not in a coma, how could they not wake up? ”

Xia Liang's conscience was shocked, and his eyes widened:

"You mean...... After the two fell asleep, they should have been stunned by the murderer with chloroform again......"

"That's how it should be."

Xia Liang was silent for a while, and the more he thought about it, the more frightened he felt:

"If that's the case, maybe this secret room really doesn't exist...... The murderer was not outside the cold storage at all, he hid in the cold storage, using the darkness in the cold storage as a cover, and waited until the three of them fell asleep again before attacking the victim...... And the audience, who was observing the situation in the cold storage, must have known that there was a box on the door, as long as it was taken down in advance, it would not cause any noise......

After muttering for a while, he frowned again: "The problem of the box is solved, but the situation of the double secret room still can't be solved...... Wait a minute...... At that time, the door outside was locked, and the murderer was inside, so it was impossible to lock the door......"

Zhu Ansheng calmly shook the mobile phone in his hand:

"Not bad. In this cold storage, the mobile phone has a signal. ”

Xia Liang swallowed his saliva:

"Brother, this shouldn't be premeditated, a group crime......
