lnmao.org, the fastest update to the latest chapter of Sin Hunter (Detective of the Underworld)!

We came to the park. Today is the weekend. There are a lot of people here. Huang Xiaotao said: "There are more people in the morning."

I said: "Buy a kite to play with."

Huang Xiaotao said in surprise: "You are serious!"

I nodded: "I haven't used a kite when I grow up, buy one!"

We came to a small stall, I picked a butterfly, Huang Xiaotao picked a centipede, it would make a noise, and Wang Dali was still picking it. I noticed a kite with a peculiar shape hung at the back of the stall. It was a small beaded swallow. It was made especially ugly. It is not that Zhao Wei is ugly, but that this kite is ugly. It is reddish, and there are two big blushes on Little Swallow's face, like a village girl, and the size is very large, the upper area is a lot of gray, and it can't be sold at first glance.

I pointed to the kite and said: "Dali, you can buy that."

Wang Dali refused without even thinking about it: "The workmanship is too rubbish, it's shameful to put this stuff, I don't want it!"

I said forcefully: "Buy me this, or don't play!"

Wang Dali said quietly: "It turns out that you are such a controlling man. I really feel sad for your future girlfriend."

Huang Xiaotao listened to her mouth and smiled, and I said: "Don't talk nonsense, hurry up!"

Wang Dali reluctantly bought the kite and held it on the road. Many people laughed at him for his wonderful taste. Huang Xiaotao smiled inexplicably: "Why are you trying to fix him? "

I said: "This is restoring the crime, vigorously, will you fly a kite?"

Wang Dali patted his chest proudly: "I have a good kite ride, I will teach you later."

Wang Dali taught us how to fly a kite. As a result, his kite was too big and swayed by the wind. On the contrary, it was not as easy to fly as our little kite.

Finally, Wang Dali’s kite flew, flying higher and higher, and it was particularly eye-catching among the colorful kites.

Huang Xiaotao stared at the kite: "Song Yang, I seem to understand your intentions..."

Wang Dali stunned and said: "What do you mean?"

I explained: "This kite is very special, right? Many people are watching the kite when it is put up. Think about the human skin kite that is bigger than it. How did the murderer put it up? Someone has called the police, so this kite shouldn't be put up, it should be thrown down from a height."

I looked around and said: "Dahlia, take the kite first, let's do an experiment!"

Huang Xiaotao and I gave the kite to the two children. Wang Dali held the big kite and went to a nearby building with us. We went up to the rooftop. I asked Wang Dali to throw the kite down.

The kite flew down in the wind and slowly fell to a tree. I asked Huang Xiaotao: "Where did the kite fly in the morning?"

Huang Xiaotao shook her head: "I don't know, let me ask!"

I said: "It's best to call the Bureau of Meteorology to see what wind is blowing this morning."

Huang Xiaotao made two phone calls and then told me that the human skin kite flew into the park square from the southeast, and the southeast wind was blowing in the morning.

I said with confidence: "Let’s experiment a few more times to determine where the murderer was at that time!"

We ran several buildings, and the kite was thrown many times and became tattered. Finally, I found the most suitable location on the balcony of the sixth floor of a building, where the kite could float to the balcony without any partiality. On the park square.

I noticed a mouthful of sputum in the corner. The color of the sputum is green and yellow, which is a sign of yin deficiency and fire, and there are some blood streaks in it. It feels like a person with respiratory diseases vomits.

I took some samples with cotton swabs and put them in the evidence bag. Wang Dali exclaimed: "Fuck, it's disgusting!"

I said, "What's the big deal? The Chinese detective Li Changyu has solved a murder case. The murderer took a pee at the crime scene. Then he locked the murderer through the test and solved the case."

Wang Dali said: "That's not disgusting!"

After taking the sample, I looked at my watch: "This time the speed of solving the case may have to break the record."

Huang Xiaotao's eyes widened: "Are you so confident?"

I said: “According to our previous speculation, the murderer is most likely an elderly person. The elderly are stubborn in their thinking and behavior has become a fixed pattern. And most of the motives of the elderly are the accumulation of old grievances. The criminal method is very laborious, leaving a lot of evidence. Combining these three points, the case can be solved by tomorrow at the latest."

Huang Xiaotao said: "If we can solve the case tomorrow, I will ask you to have seafood."

I said to Wang Dali: "Let’s stop eating tonight and wait for a big meal tomorrow!"

Wang Dali made a slobbering gesture: "Then I will start a hunger strike at noon today."

At this time, Sun Bingxin called: "Big Brother Song Yang, where did you go? I tested something."

I said: "Come back here and wait for us."

We went downstairs, and when we left the community, I asked the security guard at the door by the way, if anyone came in by car in the morning, the driver was an elderly person, and the security shook his head and said that I didn't see it.

I glanced at the camera head and asked, "Is there a surveillance video?"

The security guard said with shame: “Our community’s facilities are old-fashioned. The residents are migrants, and often don’t charge full property fees. These cameras are broken and have not been repaired. They are just pretending to be." /

Huang Xiaotao asked me: "Why do you think the murderer came by car?"

I said: "It's such a big kite, and it can't be folded. It's so arrogant to hold it into the community. The murderer must have a car! Unless..."

Huang Xiaotao took over: "Unless what?"

My eyes lit up: "By the way, you ask someone to find out where the old man lives!"

Huang Xiaotao complained: "If you don't finish speaking, you have to die me!"

We went back to the game, and Sun Bingxin asked where we went to play. I said we went to fly the kite. Sun Bingxin pouted and said: "You didn't call me when you fly the kite. It's too much!"

I said: "Flying a kite is also for investigating the case. By the way, what about your test results?"

Sun Bingxin took out a report saying that some salivary enzymes were tested on the human skin kite, which was not the same as the DNA of the deceased. It should have been left by another person, most likely by the killer who sneezed.

I nodded, and handed her a sample of the sputum and the old man’s DNA, and said: "Thank you a little bit, and test this sputum to see if it matches the saliva remaining on the kite? In addition, focus on comparing human skin with The DNA of that scared old man."

Huang Xiaotao asked: "Why compare the two sets of DNA, Song Yang, what kind of medicine do you sell in the gourd?"

I said: "It's not that I sell Guanzi. I still don't know how to say it. I will wait for the test results to come out."

There are some vague conjectures in my mind, which are troublesome to say, and my conjecture may not be correct, so I must confirm it first.

Huang Xiaotao smiled and said: "As a workman, you can learn from modern technology very often!"

I said: "The method is not important. Which method is helpful to solve the case is used. I believe that if Song Ci is alive, there is such a convenient technology, and it will not be left unused."
