"How?" Su Xiaonan asked nervously.

Fang Xinling lifted her left palm from her arm, revealing a small pool of red blood and the dried corpse of mosquitoes.

"Isn't this just a mosquito that has been killed—" Xie Bo said, his eyes widening suddenly.

"Xinling, you want to." Yang Peiwu opened his mouth slightly in surprise.

"Yes, he can cover up the physical evidence, but he can't escape the mosquito's mouth like us, I only went there for more than half an hour, you see how many bags my two arms were bitten, I don't believe that there was not a single mosquito bite him on the spot." Fang Xinling showed her two little arms that had been planted by mosquitoes to everyone, and smiled confidently.

"Wit!" Su Xiaonan gave Fang Xinling a thumbs up.

"But it's been a day, and the mosquito's blood should have been digested, and if it bites someone else during this time, isn't the blood we got useless?" You Jun frowned.

"Nope! The mosquito sucks enough for a few days each time it sucks blood, and it only feeds one person at a time, and then it flies to a dark, damp corner to digest the blood, so we still have a chance, if we can find the mosquito that sucked the killer's blood, then we can get a sample of the murderer's blood. Fang Xinling shook his head.

"Xinling, you can think of this method and can use this method, if we are allowed to catch them one by one, I don't think we can catch them for a year and a half." Xie Bo sighed.

"Tongtong's method is very feasible, You Jun and Xiaonan, you two will go with Tongtong later." Li Chengfeng said.

"Aren't you going with me?"

"I have something to do later, I have to go to the Ning Bureau, I can't accompany you, you can go to my desk and get that bottle of toilet water when you leave."

"Okay, wait for my good news."

"Team Li, what about me and Peiwu?" Xie Bo asked.

"Uncle Xie, go to the place where Wei Juan disappeared to see if you can find any useful clues, and then confirm the road monitoring when Wei Juan disappeared; Peiwu, please study the metal chips found at the scene again and see if you can find their source. Li Chengfeng said.

Office of the Director.

"Chengfeng, you're here, sit down." Ning Ke waved his hand and let Li Chengfeng sit on the chair next to him.

"Ning Ju, have you found the file of my mother's car accident?" Li Chengfeng couldn't wait to ask.

"Chengfeng, it's the first time I've seen you so anxious." Ning Ke pursed his lips and smiled, then bent down and took out a document from under the table, "Well, I found it." ”

Li Chengfeng wanted to reach out and take it, but was held down by Ning Ke.

"Chengfeng, I don't want you to watch it, it may disrupt your current life, even if it is, are you sure you want to watch it?" Ning Ke said with a solemn expression.

"I'm sure! I climbed step by step to the present, just to read my mother's car accident file. Li Chengfeng replied without hesitation.

Ning Ke sighed lightly and let go of the file, Li Chengfeng got the file and began to read it quickly, Ning Ke silently lit a cigarette on the side, the smoke slowly rose in the air, and Li Chengfeng's face slowly blurred.

Li Chengfeng put down the file in his hand, and Ning Ke had already smoked a few cigarettes on the side.

"This car accident was not an accident!" Li Chengfeng looked up at Ning Ke, with anger in his eyes, and said angrily, "The incident happened on the outskirts of Xinyang, ten kilometers away from where my mother works, in a remote location and there is no road monitoring, if someone didn't deliberately ask her there, she would definitely not have passed, this is a naked murder case!" How did the police at that time handle the case? How can this car accident be recognized as a negligent car accident? Only one year in prison for that driver! ”

"Chengfeng, I've read the dossier, and I have the same idea as you." Ning Ke snuffed out the cigarette in his hand and said with a complicated expression, "But it is very difficult to overturn the case, almost very little, unless you find conclusive evidence that can prove that the car accident that happened back then was not an accident." Judging from the current situation, it is basically impossible for you to find physical evidence, only human evidence! It's the person who planned it all back then. And the resistance you face is by no means limited to the outside, because once it is judged that this is a wrongful case, it means that the police who led the case back then were derelict in their duties! ”

"No matter how difficult it is, I have to check it out!" Li Chengfeng's eyes were firm, "Brother Xu told me that just because the police made a mistake, you can't indulge him to make mistakes again and again, and the wrong things will be corrected, this is the inevitable trend of social development!" Society is progressing, and we police must also progress! ”

After listening to Li Chengfeng's words, Ning Ke was stunned for a moment, and then laughed slowly: "Hahahaha, it seems that I am really old, and my consciousness is not as high as the young people I am now, Jing Shen is right, the more I have done it over the years, the more I have gone back." ”

"Thank you, Ning Bureau, if there's nothing to do, I'll go back first."

"Okay, let's go, let's go."

Fang Xinling, You Jun and Su Xiaonan searched for a whole day at the scene of the crime, basically searched the dark and damp corners of the area, and when they came back, they were covered in mosquito bites, and the three of them handed over the fifteen blood samples collected to Yang Peiwu and then went home to make up for sleep, and Yang Peiwu kept comparing the blood samples for laboratory testing.

Fang Xinling slept on the bed for more than ten hours before he recovered, and Li Chengfeng happened to call at this time.

"Are you awake?"

"Well, my head is still a little groggy." Fang Xinling gently pushed the skull a few times with his hand.

"Do you want to sleep again?"

"No, is the blood sample comparison result out?"

"Come out, thirteen of the fifteen blood samples you brought back are from the police station, and one belongs to the migrant worker who reported the crime, and the remaining blood sample should be the murderer."

"Is there only a blood sample of the murderer? Still haven't found it all. Fang Xinling said with annoyance.

"You've done well enough, and finding a blood sample to keep as evidence is a breakthrough." Li Chengfeng comforted softly.

"Is there something about you calling me out of the blue?"

"Brother Xu called me just now, saying that he was free in an hour, and asked if you could meet?"

"In an hour?" Fang Xinling was so shocked that he stood up directly from the bed.

"Can you do it over there?"

"Yes, I'll pack up and go out now."

After hanging up the phone, Fang Xinling immediately ran to brush his teeth and wash his face, and then changed into a new dress.

"Mom, I won't be eating at home later." Fang Xinling shouted at Yan Lei in the kitchen.

"Where are you going in such a hurry?" When Yan Lei ran out, Fang Xinling was already gone, and said helplessly, "This kid, just came back and ran out with me for a while." ”

When Fang Xinling arrived at the café, Xu Jingshen hadn't arrived yet, only Li Chengfeng was waiting by the window. Fang Xinling saw that Li Chengfeng was seriously looking at the information of the previous case, so he wanted to tease him, first patted him on the left shoulder, and then squatted down.

Li Chengfeng turned his head and found that there was no figure, and then noticed Fang Xinling, who was shrunk into a small ball, and unconsciously smiled.

"Tongtong, you're doing this again?" Li Chengfeng said dotingly.

"It's not fun, can't you just pretend?" Fang Xinling muttered dissatisfiedly.

"I've been playing for many years, and I'm not tired of it."

"It's not the right time for me to come." A pleasant male voice suddenly rang out.

Fang Xinling turned around and looked, and immediately froze in place.

"Great God Xu?"

After many years, the years don't seem to have left any traces on Xu Jingshen's face, he is still so handsome that people can see him in the crowd at a glance, the cold and arrogant aura on his body is much less than when Li Chengfeng first met, there is often a faint smile on the corner of his mouth, and the starry eyes seem to be deeper and brighter, as if they can penetrate people's skin and go straight to the depths of his heart.

"Brother Xu." Li Chengfeng said.

Xu Jingshen bowed slightly to Li Chengfeng, which was regarded as a greeting, and then looked at Fang Xinling with interest: "You are Fang Xinling?" ”

"Well, Xu Dashen, hello." Fang Xinling looked at Xu Jingshen nervously, wanting to shake hands with him but didn't dare.

Xu Jingshen saw Fang Xinling's intentions and took the initiative to hold her hand.

"Hello, in the future, you can be like Chengfeng, just call me Brother Xu, don't call Xu Dashen, I feel uncomfortable listening." Xu Jingshen smiled slightly.

"Got it, Brother Xu." Fang Xinling nodded.

"Xinling, don't you mind if I call you that, right?"

"Don't mind, don't mind."

"It's the first time I've seen Cheng Feng smile so happily, this should be all your credit, right?"

"No, in fact, he was quite cheerful and laughed when he was a child, but when he grew up, he encountered some things to suppress this side."

"You've known each other since childhood?" Xu Jingshen said in surprise.

"yes, it's still him talking to me."

"Then you have to cherish this fate, don't be like me and Yan Yue, because of a misunderstanding, we wasted a few years of time in vain."

"We will." Li Chengfeng held Fang Xinling's hand.

But Xu Jingshen didn't mention Fang Xinling's special abilities from beginning to end, and they were all chatting with them about some trivial things, until when they were about to leave, Xu Jingshen suddenly stopped Fang Xinling and looked at Li Chengfeng: "Chengfeng, I want to talk to Xinling about some personal matters, can I trouble you to avoid it?" ”

"Okay." Li Chengfeng hesitated for a while and walked out.

"Xinling, do you know Fangzheng?" Xu Jingshen looked into Fang Xinling's eyes and said slowly.

"Xu-Brother Xu, how do you know about my father?" Fang Xinling's mouth opened wide in disbelief.

"It looks like I thought, he really has something to do with you." Xu Jing smiled deeply.

"Brother Xu, you-"

"Do you know about the serial murders in the night?"

"Of course I do."

"Although the police department announced to the public at that time that the case had been successfully solved, only our insiders knew that the case was not over." Xu Jingshen's starry eyes dimmed.
