Dong Huasheng beckoned several policemen to go with him to investigate the place where there was still mud at the construction site, but Li Moyang did not immediately follow.

This old fat man...... Wrong......

Normally, the expression of surprise is fleeting, only flashing in the pupils and on the facial expression for a maximum of a second, and then it will turn into fear or anxiety, but just now Dong Huasheng looked down at the mud on the deceased's shoes, and his face was full of surprise from beginning to end......

Besides, if he was really surprised, it should have been when Li Moyang pointed out that the mud on the deceased's shoes proved that this was not the first scene, and it was normal for him to be surprised, but he was not too surprised at the time, but only began to be surprised after squatting down......

More than a second of surprise is faked.

Not to mention that this guy's surprise was delayed for several seconds......

Also, when he asked me if the murderer had transferred the body, his eyebrows were visibly raised, which is typical of knowingly questioning.

Don't......

"Mr. Li, the approximate time of death of the deceased can be determined," the policeman who had been checking the body next to him suddenly said coldly, "It was probably between three and four o'clock last night, and the cause of death was a thin and wide sharp object piercing the heart, although there were obvious pinch marks on the neck, it would not be a fatal injury, and the possibility of suicide could be completely ruled out,"

Li Moyang smiled and nodded, and said, "Thank you for your hard work", and he picked up his things and prepared to leave.

Li Moyang thought for a moment and stopped him again, "By the way, can you be sure what the murder weapon is?" "Not yet...... But it should be a knife like a watermelon knife, otherwise the wound would not be so long, and it almost penetrated the entire chest cavity of the deceased...... "I know how to go, Xie Lu Xie." "You're welcome, it's my business."

Seeing him go away, Li Moyang realized a very important problem that he had been ignoring.

Where is the murder weapon?

Not far away, Dong Huasheng and the police were at the corner of the research site, where the sun could not be exposed to the sun, so the mud was not dry.

Li Moyang hurriedly chased after him and asked anxiously: "Boss Dong, after three o'clock last night, will anyone leave this construction site again?" "

Boss Dong continued to look dumbfounded, and shook his head, "It's impossible, the workers will go back to the dormitory to sleep after ten o'clock, who will run outside in the middle of the night......"

Li Moyang was not at ease, and pulled them to the doorman to confirm that no one left the construction site to go outside last night.

In this case, the murder weapon should still be somewhere on the construction site...... Li Moyang explained to several policemen, and asked them to increase their police force to search the construction site, it is best to mobilize a few police dogs, if the murderer and the murder weapon are in the construction site, they must not be allowed to escape!

Sitting in the rest room of the construction site, watching through the window as the police officers rummaged through boxes and cabinets and crawled inside and outside looking for knives that might be the murder weapon, Li Moyang was not idle, and continued to ponder the entire case. The more he thought about it, the more uneasy Li Moyang felt in his heart. He couldn't figure out why the dead died with his coat open at night, when it was so cold......

Knock knock, a knock on the door interrupted Li Moyang's train of thought, and Dong Huasheng pushed the door into the house with a cup of tea.

"Inspector Li, it's so cold, let's have a cup of hot tea." Li Moyang turned out to be a cup of tea, and he smiled on his face, "Boss Dong said that I laughed, where am I a detective, a little detective, don't lift up Li Moyang." "

He twisted his fat body and sat on a rattan chair next to Li Moyang, and the chair creaked and screamed, "Mr. Li, you are too modest...... So what, how, some clues? In your opinion, who is the murderer? "

Li Moyang took a sip of tea, closed his eyes and sorted out his thoughts, "Hmm...... The most important thing at the moment is not to discuss who the murderer is, and after finding the murder weapon, I think the case will naturally move forward...... By the way, Boss Dong, do you know the deceased? "

Dong Huasheng touched his chin and thought about it, "Lao Song is actually not very familiar with him, he knows each other, but I haven't met him two or three times in total, and the last time we met was two months ago, he came to our construction site to inspect it, and he went to ...... again It was the first time we met, it was the annual meeting of our group last year, the company appointed him as the chief engineer of our project, and I gave him a letter of appointment on behalf of the company......"

"Wait, I remember...... I heard from the police that the deceased was appointed chief engineer only half a year ago in the summer, so why did he ...... last year?"

Li Moyang frowned and asked Dong Huasheng, but he took his question very easily, "Hey, isn't there something wrong halfway through, and it hasn't been announced to the public?" It's just a matter of form, in short, as soon as the subway is built, he is our chief engineer, and he is fully responsible for all the project design and engineering construction, and he announced his ...... as the chief designer and chief engineer after he made the overall design report on the subway construction of the entire H city last summer."

Li Moyang was drinking tea and turning his brain quickly. The overall report of a project is not done until half a year after the construction of each project has begun, which is a bit too unusual......

After taking a sip of tea, Li Moyang asked again, "Then, Boss Dong, it's inconvenient for you to reveal to me, what is the reason why Chief Engineer He announced it to the outside world half a year after taking office?" Do you have any insider information about your company? "

As soon as he heard Li Moyang throw this question, the relaxed expression on Dong Huasheng's face suddenly disappeared mostly, he leaned on the back of the chair, hugged his chest with his hands, hooked the legs of the chair with his feet, and his eyes flickered a little, "What's this...... Mr. Li, as you know, this subway project is planned by the government after all, and many details are not convenient for immediate disclosure to the outside world......

"But now that Chief Engineer Song is dead, what else can't be said?" Li Moyang interrupted Dong Huasheng's words and questioned him a little angrily.

"In the morning, in the face of a corpse, you actually regarded me as a thief rather than a murderer, I would like to ask you, in your eyes, is human life or interests important? Is it possible to ignore a bloody human life in order to protect interests? You're too ......."

"I know it! Of course I know it! Otherwise, I wouldn't have ......" Dong Huasheng suddenly stood up, looking a little excited, but he suddenly choked in the middle of speaking, biting his lip, frowning his eyebrows, raising his eyelids, and squeezing out a sentence to Li Moyang for a while.

"Mr. Li, I have no objection to your investigation of the case, but don't casually involve the matter to me and my company, I don't know anything about Song Wen's death, please don't ask again......"

With that, he walked out of the room angrily, slammed the door hard, and made a loud bang, which echoed in the lounge for a long time.
