The car slowly drove up the viaduct.

Zhong Tianzheng steadily controls the steering wheel. The speed is not fast and the driving is very stable. However, Ah Xiang keenly found that Zhong Tianzheng is a little distracted.

"What do you perceive?"

Ah Xiang took back her eyes and looked out of the window: "do you think this case involves Chen Rong?"

"Yes."

Zhong Tianzheng did not deny: "very strange, very inexplicable."

"In the case of Chen Rong, do you agree with the final conclusion?"

"Approval."

Although Zhong Tianzheng did not participate in the murder of Chen Rong, he applied to check the file of the whole case. There were no mistakes in the investigation process, and the perpetrator has been detained and sentenced.

If he just saw Meng Shi's personal information and interpersonal relationship data, Zhong Tianzheng would think it was a coincidence, but when he saw the avatar of the other party's mom account, he was sure that it would not be a coincidence.

What is this man's purpose? What does he want to express?

Is there another secret in the Chen Rong case?

"I think don't rush, everything will come to a final conclusion."

Ah Xiang comforted: "I think Chen Rong must be a very happy girl who can make you care about it."

"Ha ha."

Zhong Tianzheng was silent, driving the car silently.

Tang Fenggang style tea restaurant.

Yan Zhaoxing was already sitting by the window waiting for them.

This is a shop they used to come to.

"A cup of frozen mandarin duck and a cup of Hong Kong style, thank you."

Yan Zhaoxing handed the menu to Ah Xiang: "what to drink, beauty."

"I'll have a Hong Kong style, too."

Ah, Xiang asked for a cup with the same taste as Zhong Tianzheng.

"She wants it hot."

Zhong Tianzheng added.

"On such a hot day, you give people some heat..."

Zhong Tianzheng directly interrupted, "tell me, what's the matter with me."

"I just want to ask, if I bring down Yao Weiqiang's company, is it illegal?" Yan Zhaoxing came straight to the point.

"Just say no on the phone for such a thing?"

Zhong Tianzheng was not surprised at all. He saw the scene with Chen Sheng clearly that day. Although he was helpless, he replied: "there must be no problem with normal competition. I don't know the details. It's a matter of economic investigation."

"Are you so impatient now?"

Yan Zhaoxing sucked the frozen mandarin duck in the ice bucket: "what? Isn't it a case of hanging in a secret room? The whole people are in a panic. "

"Do you know?"

Zhong Tianzheng raised his eyebrows and white eyes.

"Yan Bing told me."

Yan Zhaoxing fiddled with the straw: "didn't this case drag on for several days? I guess you must be tired of this case. "

"Do you have a good idea?"

"I can't talk about high opinions. I can still give a little advice."

Yan Zhaoxing looked up at the ceiling: "this case is similar to the death in the secret room. If you haven't solved the case, it must be that the monitoring can't see it. If the monitoring can't see it, you must go in the path that the monitoring can't see."

"People can't be invisible, can they? You are patient. Although monitoring is so popular now, people with a little awareness will certainly avoid monitoring. "

"Thank you for your advice."

Zhong Tianzheng took out his mobile phone and began to make trouble. After a while, he put his mobile phone on the desktop: "did you have any opinion on the Chen Rong case?"

"No."

Yan Zhaoxing glanced at the file photos on the screen: "I hold the same view as you on this point. I think it's more appropriate for you to ask Yu Cheng about this question. Doesn't he always think that the Chen Rong case has not been thoroughly investigated?"

"OK, I see."

Zhong Tian nodded and got up to leave.

Ah Xiang put down the spoon, nodded to Yan Zhaoxing, and then got up and left.

Yan Zhaoxing looked at their backs and said with a smile, "little beauty, I think you should have your own opinion. You haven't drunk the milk tea yet. Don't go until you finish."

There were only two crisp figures who responded to him.

"Oh, what a coincidence."

At the door, Zhao Wan with big frame sunglasses just pushed the door in and said enthusiastically, "handsome Zhong, you just have dinner together?"

"Another day."

Zhong Tian nodded and passed by.

"Shit, people are so high and cold now."

Yan Zhaoxing smiled at the scene at the door and began to play with his little wax string.

……

Xicha road.

The site has been closed.

They put on rubber gloves and shoe covers and entered the crime scene.

"Bypass the monitoring. Where will you come in?"

Zhong Tianzheng looked up at the ceiling and asked questions every day.

Ah Xiang glanced at the window with anti-theft bar: "the first choice must be the window."

Zhong Tianzheng went to the window and looked at the window with anti-theft bar: "what else?" The tiles in front of me are somewhat reflective and dazzling.

"Ceiling above the head."

"What else?"

"No more." Ah, the role of Xiang was replaced very quickly, and there was no good airway: "there are only these two ways. Is it difficult to get out of the sewer?"

"That's a good idea."

Zhong Tianzheng folded into the toilet and glanced at the two toilet tanks. This possibility was excluded. Then he moved a ladder and climbed up the ceiling.

The hollowed out ceiling is a light sheet of iron, with several iron tie rods used to bear the load in the middle. They climb inside along the load-bearing iron frame and enter the exhaust channel.

After climbing about one meter inside, the ventilation pipe became narrow at the turn, and finally narrowed to 20 cm. There was no way to enter.

In other words, the suspect certainly didn't climb in here.

But.

The window is sealed again. How did people get in?

Zhong Tianzheng returned to the ground again and his sight fell on the window with anti-theft bar.

To be exact, it should be bright reflective windowsill tiles.

My mind suddenly opened up.

"I should have thought of it."

Zhong Tianzheng walked out quickly, followed by Ah Xiang. In the twinkling of an eye, he saw Zhong Tianzheng get into the women's toilet next door.

"No, Zheng, you..."

"Why?"

Five seconds later.

Zhong Tianzheng appeared in front of Ah Xiang and looked down at Ah Xiang's head. A brain Bang bullet was on her forehead: "what are you thinking?"

"I went to the women's toilet just to verify the working attitude of my cleaning aunt in this store."

Zhong Tianzheng pulled his hand and rubbed the Ah Xiang on his forehead and turned into the men's toilet again: "I've seen that the tiles on the windowsill in the women's toilet are not clean. They are completely in two states with this side. Therefore, the tiles on the windowsill have been wiped."

"In other words, people come in through the window."

"However, the window is sealed, and the anti-theft bar is normal."

Ah, Xiang's sight fell on the four screws of the anti-theft bar, which were all normal rust marks.

"Take a closer look?"

Zhong Tianzheng stretched out his hand and pointed to the nut: "although the four screw interfaces have been cleaned, there is still a little rust dust left."

Ah, Xiang, reach out.

The nut was easily unscrewed.
