But instead of doing so, he chose to be in a city that was easily exposed. The pen "Fun" Pavilion www.biquge.info can explain three things from this: first, the murderer can't get out of the city or this range; second, the proportion of people with type O blood in the population is generally 10-20%, and you can find one at will. He could have chosen a place or person that was not easy for people to find, but he didn't, which shows that the murderer doesn't need type O blood. Well, this is easy to explain, the specific rarity is panda blood! Three, he must have known the blood type of these people in advance! The third one is the point. This kind of blood type is called one part per million, and there are tens of thousands of people in this small county, so the proportion is quite a lot. And if you can get into contact with the blood type of the deceased, don't ask!

"Old Tao! I really wasn't very convinced of you before, so I found Zhihai and just wanted to suppress you! But today, listening to Zhou Yu's words, it is really better than blue! Served! Zhou Yu, you're right, after we tested it again, the blood type of the two dead people was indeed panda blood. The blood type of the woman who died in '07 was also undetermined in '97 due to the backwardness of testing at that time. However, it should also be. Professor Liu really has a different view of Zhou Yu, just relying on such old information, he can analyze this case inseparably, and he really has the style of Tao Futang!

"Yes, it has not been in vain for my cultivation in the past few years." Tao Futang touched the beard on his chin and said with a smile.

"Then you have a direction to investigate?" , Professor Xu asked.

"You're not talking nonsense!" , Professor Liu choked on Professor Xu.

"I've been secretly visiting this for the past few days, so what else do you gain from this?" , Professor Tao was stunned at this time. Just have two compliments, otherwise this kid will have his tail cocked.

"Professor Xu, Professor Liu, what are the results of the wound test?", Zhou Yu did not answer Professor Tao's words, but asked the two of them instead.

"What do you feel?" Professor Liu was interested in listening to Zhou Yu's analysis.

"Judging from the analysis of Forensic Doctor Qian at the meeting, it is definitely not a human or an animal tooth! I'm afraid you won't be able to detect it anytime soon! Zhou Yu thought for a while and said with some uncertainty.

"You're really amazing!" Professor Liu and Professor Xu were taken aback. Unexpectedly, Zhou Yu knew that they could not detect the composition of the murder weapon just from Qian Shaohua not introducing the wound at the meeting!

"Yes, in the last two days we have re-examined the evidence that we have retrieved. Basically the same as Qian Shaohua's test. Except for the two main things,.... "As soon as I said this, I heard footsteps coming, it was Tao Ranran, and they were back."

"When you have the strength, come to the forensic department, and we will talk to you in detail. As for you Lao Tao, why should you go? Professor Liu said unceremoniously to Professor Tao.

"You two," Professor Tao said, pointing to the two of them, laughing and crying.

"Come on, your naan! And soup. Zhou Yu took a look and found that it was Tao Ranran who spoke, but it was Li Zhihai who was not idle on his left and right hands. However, I was really happy to see him stumbling around.

Zhou Yu felt it, his body was almost recovered, and he wanted to get up and get dressed. When Tao Ranran saw it, he quickly took his coat for him.

"Thank you!" , Zhou Yu can only say this, this Tao Ranran took care of herself for a long time, and bought food, and I don't know what she was thinking.

"You're welcome." , Tao Ranran replied with a smile.

"Boy, it's okay!" After speaking, Professor Liu left with Li Zhihai, whose eyes were on fire.

Professor Xu saw that Zhou Yu had nothing to do, and left to continue his test.

As soon as the two left, Professor Tao's face immediately changed from serious to smiling: "The kid is good, I didn't cultivate it in vain, give me a long face!" Haha, since this old Liu had a student like Li Zhihai two years ago, he gave me a sigh when he met! Well, you just analyzed it, and it directly made them stunned! Work hard, keep up, be humble, you know, you are still far from what I achieved at your age! After Professor Tao finished speaking, he left with a smile while eating.

"This kid is so much better than I was at this age! If this continues, don't I want to train a detective? My vision is still very good! When he went out, he turned his head to look at Zhou Yu, who was chatting with Tao Ranran, and Professor Tao was talking to himself!

"Cut! Brag. Tell me, what did you just say to make him so happy? Don't even know that your beard is about to be pulled off? Tao Ranran first despised his grandfather, then took Zhou Yu's hand and asked curiously.

"Your grandfather said that the proudest thing in his life is to give birth to your father and then have such a promising granddaughter!" , Zhou Yu turned to Tao Ranran with a smile, gently took out his hand, and sat down to put on his shoes.

"Really? Grandpa never complimented me to my face! Tao Ranran's excited face turned red, lying on the back of Zhou Yu, who was bent over.

"Hey, Miss, I'm tying my shoes, are you trying to break my waist?" , Zhou Yu straightened up, not that he couldn't stand the weight, but that the two plumps were too sensitive to press directly on his back!

Coming to the archives again, Zhou Yu asked the management police officer directly: "Xiao Xu, I looked at it last night, there are only paper files from 90 years ago, what about 90 years ago?" ”

"Officer Zhou, you said 90 years ago. It was rebuilt in 2000, and 90 years ago, I heard from the bureau chief that it seemed to have been put in the prefectural archives. Xiao Xu thought about it for a while and finally remembered it.

"Thank you," after speaking, Zhou Yu walked towards the physical evidence testing center. Tao Ranran didn't follow, went back to the dormitory, and didn't know what to do.

The weather in the northwest, strong winds and heavy rain, is also coming. Especially near the foot of the snow-capped mountain, the sun may be shining, and the snow will flutter in less than half an hour. Don't be surprised if you do.

At this time, there is no cloud outside, and the sky is blue and dazzling!

There are still hidden traces of water on the stone floor, but the dirt pavement has dried and cracked, and if it hadn't been for the rain yesterday, it would have been thought that it was sprinkled with water.

When he came to the forensic department, he asked Li Zhihai to come out to pick him up, and the police let him in. When I got to the house, I swiped my card and entered my fingerprints before I could go to the basement. This is the testing center. In the entire police station, this basement and gun room are the strictest!

"Here we are." When Professor Liu saw Zhou Yu, he pointed at Li Zhihai and signaled that he didn't have time.

"The results of the test are on that computer, and you can see them when you click on them." , Li Zhihai took him to a table, didn't care, walked to the front of the machine again, and continued to do the test.

Zhou Yu clicked on the computer and saw more than a dozen folders on the desktop, all of which were from these two cases, and among them, there were two of which he was most interested in.
