In the monitoring room of Yongle Electronics Company, Yang Ziqing's long figure was bent across the ground, accompanied by dim lights, and the entire monitoring room looked particularly terrifying, as deep as a morgue in a horror movie.

The first time Li Qing walked into the chairman's office was the day before the crime. Yang Ziqing directly adjusted the monitoring record to the scene when Li Qing walked into the chairman's office:

The above shows that on January 31, at half past eleven in the morning, Li Qing walked out of the sales department with a thick file bag, walked to the chairman's office, knocked on the door and walked in! Li Qing did not close the door immediately, but left it ajar. Yang Ziqing could clearly see through the crack in the door that Jia Qinghou was still standing with his hands behind the door facing the window, as if he was still angry about the quarrel with Jia Kun just now!

After Li Qing's body walked in, it was covered by the ajar door, but he could just see Jia Qing standing in front of the window, he didn't look back at Jia Qing, just put down a hand, raised it to his earlobe and waved, ignoring it!

Li Qing didn't stay long, and in just a few seconds, Li Qing appeared at the door, walked out, and closed the door! He waved the file bag with a puzzled expression, and inadvertently glanced at the camera, just opposite Yang Ziqing, who was watching the video.

Yang Ziqing froze the picture again, looking at Li Qing's eyes from the surveillance video, he slowly enlarged the picture, and completely displayed Li Qing's eyes on the screen, and a deep and hostile look was staring at Yang Ziqing deeply.

"Could it be that he has laid down the mechanism to assassinate Jia Qing for a long time in these few seconds? What can be done in these few seconds is exchanged? Yang Ziqing pondered carefully in his heart, and he couldn't figure it out. He tuned this video back and forth, and Li Qing kept running back and forth in the picture.

Time passed second by second, but he couldn't find any flaws, and suddenly Yang Ziqing noticed: The file bag in Li Qing's hand was a little awkward. Yang Ziqing hurriedly adjusted the video, looking back and forth at the difference between Li Qing's file bag when he went in and came out.

In the winter, the fingers have been in the open state for a long time, and they seem to be extremely cold, and the fingers are frozen in an instant, and they are a little disobedient.

Suddenly, Yang Ziqing's heart suddenly boiled, and said: "I finally know, the file bag in my arms when I went in was thick, and when I came out, the file bag became much thinner!" Unless you put something in it? Portfolio? Yang Ziqing suddenly had this signal in his mind, and remembered the pile of thick materials and documents on Jia Qing's desk when he was inspecting the location of the crime yesterday.

"Is that the poisoning method?" Yang Ziqing walked out of the monitoring room with a willful attitude, called the security guard in the security room next door, and boarded the elevator upstairs.

Yang Ziqing came to the chairman's office again, and the office with the lights turned on was particularly dazzling. The contents are marked with triangular squares, and the markings of loose objects on the desk and under the table are densely laid on them.

Since the miraculous death of the chairman of the whole building, the employees have all taken a holiday, and there are only a few security guards and Yang Ziqing left in the whole building. Silence and terror spread throughout the building, and it was particularly cold in this night without gunsmoke.

The security guard who opened the door shook off: "We haven't touched the evidence in the office, and it still maintains its original appearance, so you can investigate slowly!" I went downstairs, it's horrible! With that, the security guard ran away, and there were several footsteps of "Dada" in the aisle outside the door.

Yang Ziqing didn't care, anyway, he had broken into a situation that was hundreds of times more terrifying, so why should he scare himself now? Yang Ziqing walked to the office desk and flipped through the pile of documents.

At this time, two documents that had been sorted out together were printed into Yang Ziqing's eyes, and he carefully held one of them in his hand. The document was fastened with a paper clip, and the contents of the document were almost a dozen sheets of A4 paper.

Yang Ziqing flipped through carefully, and there were several big words "marketing plan" in the center of the first page, and under the four big words was a line of small words: Jia Kun, the drafter. Yang Ziqing also roughly browsed the content inside, the board style of the content is simple, the conditioning is clear, and the analysis is in place, which is almost some plans for the later sales of products. It seems that this is the result of Li Qing's analysis! Could it be that this is the document he put here with Jia Qing behind his back? And what about the documents that Jia Kun brought in yesterday morning? ”

Thinking of this, Yang Ziqing put down the document in his hand and picked up another one. This document is in the same format as the first one, and it is also fastened with a paper clip, and the text on the first page of the document is the same. Yang Ziqing carefully opened the document, but his heart was suddenly shocked, and said, "How can this document have a bitter taste?" The A4 sheets in the middle seem to be damp, and they are full of uneven wrinkles left by the water infiltration, although the paper is so dry that the watery liquid can no longer be seen, but it can still be inferred.

"Bitter almond flavor? Potassium cyanide! Yang Ziqing's mind suddenly burned with an idea, and he suddenly fell into deep thought: According to the time when the two documents came in, the first document placed on it should have been sent in by Jia Kun yesterday morning! And this wrinkled document should be Li Qing's! In this way, the murderer should have placed the potassium cyanide powder in the folder, and when Jia Qing read it, he would inhale it and die of poisoning!

"Wait! If Jia Qing really flipped through Li Qing's documents and was poisoned by inhaling potassium cyanide, then his document should be placed on it! Yang Ziqing suddenly felt that there was still a loophole, holding a document in one hand in both hands, frowning, and scanning back and forth between the two documents with his eyes tight.

Suddenly, Yang Ziqing's eyes lit up, and he found a small pale yellow dot on the side of the bottom of the first document. At this time, Yang Ziqing instantly became enlightened, he slowly put down the file, and said with a comfortable smile: "The mystery is finally revealed!" ”

In the warehouse on the outskirts, except for the laughter of the short man in black, there was the biting sound of the wind, and a thick haze emanated from the dim light.

With the short man's order, the tall man raised the iron rod in his hand and slashed at Han Wei's head. With a loud "boom", the tall man suddenly felt that the palm of his hand was shaken by the iron rod, and he instantly became numb. He steadied himself and looked forward, a stout hand gripping the iron rod swung by the tall man.

The short man was also taken aback, standing aside, looking at this mysterious man with short hair, a serious face, two thick eyebrows, a high nose bridge, embarrassed eyes, and a tall and majestic body exuding a thick domineering aura, his eyes suddenly flashed golden and said, "Isn't this Officer Ma?" ”

"Police?" When the tall man heard the short man's words, he quickly let go of the iron rod in his hand like a conditioned reflex, stepped aside, and stared at the short man with a surprised face. Ma Long took the iron rod and threw it to the ground, then half-squatted beside Han Wei, and his two big hands directly broke the rope on Han Wei's body. Han Wei, who was already on the verge of collapse, suddenly collapsed, leaned on Ma Long's lap, looked at the vague Ma Long and said, "Save Xiaoli!" Save Xiaoli! ”

Ma Long was a little anxious, and he was about to put down Han Wei to untie Xiaoli who was tied up next to him. The tall man hurriedly interjected: "This girl is fine, we didn't torture him, but he shouted for a long time and fainted!" ”

Ma Long glanced at Xiao Li, who was tied to the pillar, lowered her head, and had no blood stains on her body and was intact, and the panic in her heart was slightly suppressed.

Ma Long's sudden arrival, this short man was not surprised, but felt as if it was logical. He walked over unhurriedly, stuck to Ma Long's side and said, "It's just right that you're here!" I was about to call the police? This kid has confessed! As he spoke, the short man pointed at Han Wei as if nothing had happened. The tall man was on the sidelines, too, and his towering eyes exuded an evil aura.

"Li Qing! You bastard, don't frame the good guys! Han Wei, who had just escaped from the Ghost Gate Pass, was lying on Ma Long's lap and yelled at Li Qing.

Li Qing didn't argue too much with Han Wei, slowly walked around Ma Long and Han Wei, took out a ballpoint pen-shaped voice recorder from his pocket, and said casually in front of him: "This is the evidence, do you want me to release it for everyone to wash their ears?" ”

"You!" The corners of Han Wei's mouth suddenly protruded from a pool of blood.

Immediately after, a sound of footsteps sounded behind him, and Li Qing and the others turned their eyes away. I saw that Jia Kun, He Yun, and Liu Yun were hurriedly running in from the small door of the warehouse. I saw two black-clothed people standing in front of me, covered in blood, lying on Ma Long's lap, and Xiaoli next to him was tied to the pillar next to him like a dead man. The dim lights in the warehouse added a lot of horror to this already bloody scene, accompanied by the cold wind, Liu Yun suddenly felt like entering hell, and couldn't help but slow down.

"Li Qing! Lose Lao Tzu when you are a good friend! Why are you taking advantage of me! Did you kill my dad? Jia Kun rushed to the front, and when he saw Li Qing who was wandering around Ma Long, he scolded loudly.

As soon as Li Qing saw Jia Kun, he instantly lowered the slightly crazy expression just now, and said resignedly: "Brother Kun! You told me to arrest someone, huh? And I've already made him confess! And with an unexpected harvest, when your father was hospitalized with a heart attack before, Han Wei, the dog man and woman, didn't go to Shenzhen at all! Why do you suspect me? ”

When everyone heard Li Qing say this, they stared at Li Qing in surprise as if they were thundering. Han Wei shook his head with remorse on the side, almost fainting.

Li Qing continued: "He has been coveting the shares of your company? As long as your dad dies, won't he get it naturally? The last time I robbed Xiaoli from you, I was indirectly angry with your dad through you, but your dad had a big life and didn't die, so he simply killed the killer now! ”

Li Qing's voice was very loud, his serious expression matched with the swing of his limbs, emitting a powerful persuasive power, and almost perfect reasoning, which made everyone secretly move their eyes to Han Wei.

When Jia Kun heard this, his heart was also shocked, and he yelled at Han Wei, who was in a daze: "Han Wei! Is he right? ”

"That's not right!"

Familiarity came from outside the door, slowly approaching with the sound of footsteps
