"In addition to ordinary people's blood, this blood stain also has a very complex molecular structure that I can't name. This molecular structure is somewhat similar to the molecular structure of stabilizers in some reactive dyes.
According to my experience, this should be a toxic substance."
The new dean replied, "Dean Zhang, after hanging up the phone, I will send you the specific information on the molecular structure."
"Okay, thank you, Dean."
Zhang Fan thanked him.
Afterwards, the two exchanged pleasantries for a few more words and hung up the phone.
Huang Qingyun on the side also heard clearly the conversation between Zhang Fan and the new dean. After a while, Zhang Fan's cell phone vibrated slightly.
"The new dean should have sent over the molecular structure of that special substance."
Huang Qingyun looked at Zhang Fan's mobile phone and said.
Zhang Fan picked up the phone and unlocked it. Without even looking at it, he handed the phone to Huang Qingyun, who observed it carefully.
"Brother Fan, look..." After looking at it for a while, Huang Qingyun handed the molecular structure picture to Zhang Fan.
Zhang Fan took a look and said: "Our test results prove that in addition to human blood, there are other toxic substances in the blood stains. This fact is enough to explain the problem. Obviously, they are not clean inside."
Huang Qingyun nodded in agreement, and then asked: "Brother Fan, what should we do next?
Find the two people responsible for the test on the test sheet?"
"The problem may not lie with them. My idea is that we meet all the people who handled this case and look for clues from their faces."
Zhang Fandao said that using fortune telling to observe their faces is the most convenient method.
"How are we going to meet these people?"
As soon as Huang Qingyun finished speaking, his cell phone rang. It was a strange number that belonged to Taishan.
"Hello...hello..." Huang Qingyun answered the phone.
"Sir, I am the girl you rescued at the food stall yesterday. Do you have time later?
I would like to treat you to a meal."
A clear female voice came from the receiver.
Huang Qingyun thought of Zhang Fan's words to him last night and said, "I don't have time. I'll contact you when I have time."
"This...that's okay."
The girl said a little disappointedly, "Then please remember to contact me..."
"OK."
Huang Qingyun responded, then looked at Zhang Fan and asked, "Brother Fan, is it okay if I handle this matter like this?"
"As long as you control the scale, it doesn't matter whether you go or not."
Zhang Fan smiled and said, "If you don't want to go, let's go have dinner now and then go find Li Qiu."
"Looking for Li Qiu?"
Huang Qingyun was stunned, "Didn't you say yesterday that you couldn't tell Li Qiu about the blood stains?
Afraid of striking grass and alerting snakes.”
"The reason we go this time is not to tell him about the blood stains, but to find an excuse to meet the people who were involved in this case a year ago."
Zhang Fan said.
"Oh..." Huang Qingyun nodded, "What excuse are you going to make?
Brother Fan?"
"You will know when the time comes. Let's go eat."
Zhang Fan said.
After lunch, the two went straight to the city bureau and successfully found Li Qiu.
"Two masters, has there been any progress in the case?"
Li Qiu got a bottle of water for each of Zhang Fan and Huang Qingyun.
"not yet."
Zhang Fan replied.
"You have only been here for a day. We have been checking for half a year and there is no progress. You two masters, don't worry."
Li Qiu comforted him.
Zhang Fan smiled and nodded.
"What do you two want when you come here today?"
Li Qiu continued to ask.
"We have read all the information you gave us and it is very detailed. However, there are some situations that may not be clues to you and were not included here, but they are very important clues in our eyes.
We came here today just to talk to all the people involved in this case and see if we can find some clues."
Zhang Fan replied.
"Indeed, there are some clues that we cannot see or notice."
Li Qiu quite agreed with Zhang Fan's words, "There were eight people involved in this case, including laboratory personnel, and I asked them to come and find two of them one by one.
Oh, by the way, Wang Li, the female forensic doctor who introduced the two people here, is still in the hospital, so I may not be able to talk to them today."
"We have already talked with Wang Li."
Zhang Fan replied.
"That's good, I'll go find the remaining seven people involved in this case now."
Li Qiudao.
"Officer Li, your time is precious. You don't have to ask them to come here alone, just come together. Each of you and I can more easily stimulate deep memories, which may lead to bigger clues."
Zhang Fan said.
"Okay, then do what you want."
Li Qiu agreed happily.
About seven or eight minutes later, seven police officers, five men and two women, who were involved in the case, came to Li Qiu's office.
Li Qiu invited everyone to sit down. Zhang Fan took a look at the faces of the seven people, and finally his eyes fell on a girl in her twenties, with a Sassoon haircut, who looked quite capable.
After learning about Zhang Fan's intention, everyone started chatting. Moreover, the girl with Sassoon hair loved to talk, and would look at Zhang Fan and Huang Qingyun from time to time.
After an hour, everyone had said almost everything they needed to say, and Zhang Fan asked everyone to leave. Before going out, the girl with Sassoon head deliberately looked curious, looked at Zhang Fan and Huang Qingyun and smiled.
: "Two masters, what kind of magic are you practicing?"
"Oh, we are all members of the Taoist sect."
Zhang Fan replied.
"Oh..." The woman with a Sassoon head smiled.
"Zhang Jing, go back to work quickly."
Li Qiudao.
"I know, leader..." Zhang Jing, a girl with a Sassoon head, stuck out her tongue playfully.
"Two masters, did you find any clues through the chat just now?"
Li Qiu asked.
"Some discoveries."
Zhang Fan replied, "However, we need to go back and sort it out. Thank you Director Li for cooperating with us."
"Isn't this all what it should be? Our goals are the same. If the case is solved, both of us can get paid, and I can get a promotion and a salary increase. It's mutually beneficial."
Li Qiu laughed heartily.
"Then we won't disturb your work and will leave first."
Zhang Fan smiled and stood up as he spoke.
After leaving the police station, Huang Qingyun couldn't wait to ask: "Brother Fan, is there something wrong with the girl named Zhang Jing with Sassoon hair?"
"Judging from the appearance, that's it."
Zhang Fandao said, "The edge of her Yintang is dark red, and there is an evil spirit lingering around it. This is the appearance of an accomplice in the murder case, and she got a lot of ill-gotten wealth from this murder case."
