Next, it should be passed that Ju Xiangbei, the general manager of Tsinghua Group.

Ju Xiangbei's first impression is that he is shrewd and capable, a middle-aged man who looks very stable, and his clothes are also quite tasteful.

Ju Xiangbei is the brother of Chairman Zeng Mao, and was once a top student majoring in information technology at Fudan.

After graduating from university, Ju Xiangbei followed Zeng Mao to start a business, and he has been saddle up until today.

From Ju Xiangbei's mouth, everyone learned that Tsinghua Group has recently encountered some operational difficulties.

From the surveillance video just now, it was found that Zeng Mao didn't seem to be very satisfied with Ju Xiangbei's work plan in the afternoon, and seemed to have lost his temper with him and dropped the cup.

However, regarding the chairman's move of smashing the cup just now, Ju Xiangbei emphasized it again:

He said that Zeng Dong's anger just now was not directed at him, but was deceived by a certain person with great power in the city, which led to anger and anger.

After sending Ju to the north, Chen Zhonghua began to analyze:

"The problem must be Guan Rong and Cao Cinu, there is a big difference between what the two of them said. ”

"Hmm!" Huang Weiwei also nodded in agreement.

Leng Ling'er had a cold face, as if she was thinking about a problem, and she took a look at the small rectangular space in the drawer again.

There was nothing to gain at the scene, so we could only temporarily close the team, and after going back, everyone had a little dinner casually, and immediately worked overtime to hold a case analysis meeting.

However, after a long day of discussion, no more useful clues were found, so Leng Ling'er could only let everyone go back to rest first.

After returning to the dormitory, Huang Weiwei went out to buy shampoo and snacks, Leng Linger was lying on the bed with her head in her arms, bored, she turned on her laptop, and inadvertently, she saw Han Zijian's QQ avatar again.

I really wanted to talk to him, but looking at his avatar, which had been dark for a long time, Leng Ling'er didn't know what to say.

No, Stinky Sword, no matter where you hide and get free, I must harass you.

So, Leng Ling'er didn't know what kind of psychology she had, and sent all the surveillance videos of Zeng Mao's office that had been copied by Huang Weiwei in her computer to Han Zijian.

That is, she sent a mess to Han Zijian, but Leng Ling'er suddenly felt that Han Zijian was still by her side, and this night, she slept very sweetly.

As soon as she woke up the next morning, Leng Ling'er was pleasantly surprised to find that on the computer that was not turned off last night, Han Zijian actually replied:

"A little fool, with a group of big fools, this video has obviously been edited, go recover !!"

Just a sentence of 'little fool' that I hadn't heard for a long time, Leng Ling'er was immediately happy, flew from her bed to Huang Weiwei, who was still in the bed, and began to babble and sing happily.

happily dragged Huang Weiwei up, the two of them went to bed to eat together, and after starting work, Leng Linger took everyone back to Tsinghua Group and immediately came to the monitoring room.

The two computer masters of the technical department of the Criminal University were busy for most of the day, and it took a lot of effort until it was dark, and finally the paragraph was completely restored, and the surveillance video was deliberately edited.

"Damn, we were actually tricked!" Leng Ling'er looked at the video of the recovery and said fiercely.

It turned out that there was a fourth person who had been in and out of Zeng Mao's office at that time.

This person is Tsinghua Group, the cleaner who is responsible for the sanitation work on the floor of the chairman, Cheng Bei.

......

At about nine o'clock that night, the weather was cold and gloomy, and Cheng Bei had just eaten and was washing pots and wiping dishes in the kitchen.

Suddenly, there was a sharp knock on the door.

Cheng Bei couldn't help but panic.

Because in this remote urban-rural junction, at this point, there are very few pedestrians on the road, at this time, who knocks on the door?

Because the security in this area is not very good, especially at night, there are often burglary cases, looking out the window at the moment is pitch black, this rapid "bang bang" knock on the door, she can't help but be afraid.

Cheng Bei came to the door in fright, and she dared to ask:

"Who?"

"Interpol, let's find out a little bit about the situation," Chen Zhonghua, who was outside the door, replied softly, disturbing the neighbors.

Cheng Bei opened the door in disbelief.

Leng Linger took Huang Weiwei and Chen Zhonghua into Cheng Bei's house, and everyone saw that in this home, all the furniture and household appliances and daily necessities were almost all second-hand, and the conditions were too simple.

Cheng Bei respectfully let the three of them sit down on an old sofa, and then went to pour water again.

"Don't be busy, sit down, we have something to ask," Huang Weiwei called Cheng Bei more kindly.

He was only in his fifties, and at the moment he looked uneasy, his hair was dry, and there were obviously many wrinkles on his face.

"Something happened to your company, do you know?" asked Huang Weiwei looking into Cheng Bei's eyes.

Cheng Bei shook her head inexplicably, and then asked with concern:

"Did the company lose something? I've been cleaning for so many years, but I've never taken anything from the company!"

Seeing that her face was full of simplicity and her eyes were full of kindness, it didn't seem like she was deliberately pretending to be stupid, Huang Weiwei reminded her:

"Your chairman, Zeng Mao is dead!"

"Ah, chairman, he, he's dead?" Chen Aiping, who was resting at home with her colleagues today and didn't go to work, flashed an imperceptible look in her eyes.

"Yes! Chairman Zeng is a middle D died!" Huang Weiwei nodded to her again to confirm.

This time Cheng Bei seemed to be frightened, she suddenly stood up, and slumped down on the chair casually.

Cheng Bei's reaction made everyone think:

Isn't your reaction a little too intense?

"What time was it when you arrived at your chairman's office yesterday afternoon?" asked Huang Weiwei as she motioned to Chen Zhonghua beside her and asked him to start taking notes.

"It's probably about five o'clock in the afternoon," Cheng Bei quickly regained her composure, and she said in an affirmative tone:

"Traditionally, I should go to the chairman's office to clean at that time, because it is almost time to get off work, and I have to clean all the boss's office on that floor. ”

"Then why didn't you clean up the broken cup?" asked Huang Weiwei.

"It was the chairman who didn't let me clean up, and when I knocked on the door and went in, I almost stepped on those debris, and then I quickly wanted to sweep it, but the chairman told me not to move, saying that I would just put it there," Cheng Bei replied very carefully.

Huang Weiwei asked again: "Then why did you return to Zeng Mao's office after you cleaned the chairman's office and left?"

After the technical department restored the cut surveillance video, everyone had fully grasped the movements of the cleaning aunt Cheng Bei in and out of Zeng Mao's office.

After gently brushing the hair on her forehead, Cheng Bei said:

"When I turned around and passed by the door of the chairman's office, I heard him cough suddenly, and he coughed very badly, so I quickly took two paper cups from another office, pushed them away, and sent them in, intending to pour water for him.

"Isn't there a paper cup in the water dispenser in Zeng Mao's office?" asked Huang Weiwei staring at Cheng Bei tightly.

"No, Chairman Zeng never uses a paper cup to drink water in the office, he only uses the cup that has been broken," Cheng Bei replied, looking very calm.

"Then what did you see when you entered Chairman Zeng's office for the second time, and what happened?" asked Huang Weiwei again.

"The second time I went in, I saw the chairman with his head up, holding a bottle of honey, drinking what little honey was left. ”

"Honey bottle, what kind of honey bottle?" Leng Ling'er suddenly had a flash of inspiration in her mind, and hurriedly interjected and asked.

At this time, Leng Ling'er was like a demon, she seemed to see a honey bottle flying in the air, and finally flew into the drawer of Zeng Mao's office, which happened to fill the space that was specially set aside.

"It's the kind of normal honey bottle sold outside, a bottle so tall and so wide," Cheng Bei said, gesturing with her hand to the size of the honey bottle.

"Do you know where that bottle is now?" Leng Ling'er continued to ask after breathing a sigh of relief.

"I don't know, and I didn't see it later," Cheng Bei hurriedly replied.

The reason why Leng Ling'er asked this is because today at Tsinghua Group, during a visit, I learned that when Cheng Bei went to work every day, she would collect all the waste cardboard boxes and various beverage bottles on the floor under her management, and then sell them to subsidize her life.

Everyone thinks that this good-looking honey bottle is naturally the target of Cheng Bei's collection.

After leaving Cheng Bei's house, everyone felt that this honey bottle had now become the key.

So Leng Linger took Huang Weiwei and Chen Zhonghua and immediately went to Tsinghua Group overnight.

But when all the security guards of Tsinghua Group were mobilized to dig three feet into the ground to find the honey bottle, a security guard hurriedly reminded everyone:

"The sanitation truck pulled all the garbage from the group. ”

As soon as they heard this, Leng Ling'er and the others immediately took a car of security guards and immediately went to chase the sanitation truck that had just left.

When she chased to the garbage transfer station, seeing that the sanitation truck was still full, Leng Linger designated an open space and asked the master to dump the truckload full of garbage.

So, under the personal supervision of Leng Ling'er, Huang Weiwei and Chen Zhonghua took more than 20 security guards to carefully rummage through the large pile of stinky garbage.

It went well, and two hours later, I really found the lucky honey bottle.

Returning to the University of Punishment non-stop, Leng Ling'er, who was originally a technical strength, was busy until the second half of the night, and after inspection, the residue of the chloride was finally detected from this bottle.

But on this bottle, there are only Zeng Mao's fingerprints.

At this moment, many questions surged into Leng Ling'er's brain at the same time:

Was Zeng Mao suicidal?

Who deliberately cut off the monitoring of Cheng Bei's entry and exit from the chairman's office?

Why did this person do this, and what was his intention?

How did the green product D get into the honey bottle?

Among the many clues, everyone studied and decided, and then went to the administrative director of Tsinghua Group to track down the surveillance video and the problem of being edited...
