After listening to the conversation between Xing Dongjie and Hongyu, a smile appeared on the corner of Zhang Leifeng's mouth, and he got up from the listening room and walked out of the room.

"Great Detective, you can."

"The Great Detective is amazing."

"It's still the same, admire."

The police officers passing by all gave Zhang Leifeng a thumbs up and expressed heartfelt praise.

Zhang Leifeng nodded to them with a smile on his face, walked out of the Public Security Bureau, and just heard the mobile phone ringing, and took out the mobile phone to see that it was Fan Miaomiao calling.

"Miao Miao, what's wrong?" Answering the phone, he asked softly.

"How's your business going? Do you want to come back for dinner tonight? Fan Miaomiao asked Zhang Leifeng.

Zhang Leifeng smiled: "Of course I want to go back, it has been solved, it is a small matter." ”

"Okay, drive slower on the road, I'll wait for you at home."

"Okay."

After saying that, the two of them hung up the phone.

Zhang Leifeng returned to the car, and as soon as he started the car, he saw Xing Dongjie running out, turned off the car key in a daze, opened the car door and walked down.

Xing Dongjie came to Zhang Leifeng and gave him a big hug: "Zhang Leifeng, thank you, thank you for helping me." He said to Zhang Leifeng very sincerely.

Zhang Leifeng slapped Xing Dongjie's back a few times: "Nonsense, I'm not here for you, okay, my daughter-in-law will wait for me to go home for dinner, I'll go first." After finishing speaking, Zhang Leifeng turned around and jumped into the car, started the car and drove away.

Is this the end of the matter? Obviously, it is impossible, as long as Zhang Leifeng opens this head, endless things will continue to appear.

His current home has become an office location again, and he always chats with Xing Dongjie while watching the children, analyzing the case and reasoning.

Xiaoning sat next to Zhang Leifeng like a small audience, looking at Zhang Leifeng with two big watery eyes, as if he was listening very seriously.

Zhang Leifeng and Xing Dongjie turned their heads to look at Xiaoning, and couldn't help laughing when they saw his serious expression: "You little guy, are you also interested in solving the case?" Zhang Leifeng hooked his nose with his hand and said.

Xiao Ning couldn't help but burst into laughter.

"Okay, let's get down to business, you tell me the case from beginning to end." Zhang Leifeng turned his head to Xing Dongjie and said seriously.

Xing Dongjie nodded: "Three days ago, a victim was found in the utility room of a factory, according to our investigation, it can be determined that he died of poisoning, when he died, he was holding a piece of paper in his left hand and a pen in his right hand, but there was not a word on the paper, the scene was very chaotic, it was obvious that the deceased was caused by pain, no footprints were extracted on the ground, and no other valuable clues were found at the scene except for the fingerprints of the deceased, I have to say only so much." Xing Dongjie told Zhang Leifeng about the entire process of the case and some of the findings.

After listening to this, Zhang Leifeng squinted his eyes, supported his chin with his hand, and his brain began to spin rapidly.

What's going on here? Zhang Leifeng had a picture in his mind, a man walked into the utility room in the middle of the night, and then ate something and suddenly felt uncomfortable, because of the pain, he waved his arms around the room in an attempt to make a sound so that others could save him, but unfortunately this is the most inconspicuous utility room in the factory, under normal circumstances, no one will come here, and the noise of the factory has machines is enough to cover up the sound in this small utility room. Eventually, the man slowly collapsed in pain, and at his last moments, he saw the paper and pen on the ground, and he crawled over to pick up the pen and paper despite the sharp pain in his body. In the last moments of his life, he must have wanted to send some kind of message to the police through this method, maybe it was the murderer, maybe it was the motive for the killing, maybe it was ......

But alas, he didn't write a single word and died there.

The picture is frozen here, Zhang Leifeng's eyes widened, and he looked directly at Xing Dongjie: "There is something wrong with this case." He muttered.

Xing Dongjie knew that there was a play when he saw Zhang Leifeng's expression, and immediately leaned over and asked, "What's wrong?" Let's hear it. He urged in a hurried tone.

"You think, since it's a utility room, and it's a utility room that has been abandoned for a while, who would go to a place like this? Also, how did he get in? What's more, why did he die the moment he got the pen and paper, but didn't insist on leaving us a little clue, these are not right, very wrong. Zhang Leifeng frowned and said these questions in a hurried tone.

Xing Dongjie was stunned after hearing this, and felt that what Zhang Leifeng said was indeed suspicious, so he immediately took out his mobile phone and dialed the policeman's number: "In this way, you immediately take someone to investigate for me, how did the deceased enter the utility room at that time, and by the way, ask whose key to the utility room is generally on his body, yes, yes, go immediately." ”

hung up the phone, looked up at Zhang Leifeng and took a deep breath: "What do you think is the possibility of this case?" Zhang Leifeng was questioned.

Zhang Leifeng shook his head with a pout, turned around and hugged Xiao Ning: "I never guess, I only speculate, I can't be sure who did it, but I can tell you who the biggest suspect is." Zhang Leifeng said mysteriously.

Xing Dongjie stood up after hearing this, as long as he was the biggest suspect in Zhang Leifeng's opinion, he was basically the murderer, and the success rate of Zhang Leifeng's speculation in all the previous cases was as high as 99%, so he was still very excited to hear him say this.

"Okay, who do you say is the biggest suspect?" Xing Dongjie couldn't wait to know this person's name.

"Who can attract a man to the utility room? Note that this utility room is a place where no one goes......" Zhang Leifeng said with a mysterious smile, he didn't say it all, he thought, I've already said it here, if you still can't guess, it can only mean that your brain is a pig brain.

Xing Dongjie was stunned for a moment after hearing this, and then clapped his hands vigorously: "You mean ......?"

Zhang Leifeng nodded slightly: "Since you already know, then don't spend it at my house, go and do your business, captain." Said half-jokingly to Xing Dongjie.

Xing Dongjie picked up the tea on the coffee table, took two sips, put down the cup and complained to Zhang Leifeng: "From the time I entered your house to now, you have poured me this glass of water, this is not good." With that, he smiled, turned around and strode out of the room.
