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 table of surprise is fleeting, only the pupils and face flash 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 o'clock and four o'clock last night, the cause of death was a thin and wide sharp object piercing the heart, although there were obvious pinching 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 about it for a while, 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 wouldn't have been so long, and it almost penetrated the entire chest cavity of the deceased...... \"\"Okay I know, thank you." You're welcome. \"

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 led the police to study the corner of the construction site, where the sun could not shine, so the mud did not dry out.

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

Boss Dong continued to look dumbfounded, and shook his head, \"Impossible, I will go back to the dormitory to sleep after work at ten o'clock, who will run outside in the middle of the night......"

Li Moyang was not at ease, and took them to the doorman to confirm that he did not leave the construction site to go outside last night.

In this case, the murder weapon should have been returned somewhere on the construction site...... Li Moyang explained to several policemen, and asked them to increase police forces to search the construction site, and it was best to mobilize a few police dogs, if the murderer and the murder weapon were in the construction site, they must not be allowed to escape!

Sitting in the rest room of the construction site, watching the police officers rummaging through the windows and crawling inside and outside looking for knives that might be the murder weapon, Li Moyang was not idle, and continued to ponder the whole case. The more he thought about it, the more uneasy Li Moyang felt in his heart. He couldn't figure out why the deceased 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 the cup of tea, and he smiled on his face,\"Boss Dong said with a smile, where am I a detective, just a little detective, don't lift 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...... What, what, do you have 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, but 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, knowing is knowing, but I haven't met him twice 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 the last time...... 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 issued him a letter of appointment on behalf of the company......\"

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

Li Moyang frowned and asked Dong Huasheng, he took his question very easily, \"Hey, isn't there something wrong with the way, hasn't it 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 of the subway construction in 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 Song only announced it to the outside world half a year after taking office?

As soon as he heard Li Moyang throw this question, the relaxed look on Dong Huasheng's face suddenly disappeared mostly, he leaned back on the chair, his hands on his chest, his feet hooked the legs of the chair, 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 the chief engineer of 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, when faced with a corpse, you actually regarded me as a thief instead of a murderer, I would like to ask you, is your life important or your interests important in your eyes? Is it to protect your interests can you ignore a bloody life? You are too ......\"

"I know, of course I know, otherwise I wouldn't ......" Dong Huasheng stood up suddenly, looking a little excited, but halfway through his words, he suddenly choked, biting his lip, frowning his eyebrows, his eyelids raised, and it took a while to squeeze out a sentence to Li Moyang.

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

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