I apologized to Chu Tianqi apologetically, he didn't have too many expressions, maybe he also knew that I had been upset recently, so let me take a break. The patchwork of the female corpse can be completed slowly by himself, and he speaks easily, but I know that it is because of my self-righteous help that all his hard work in the past few nights has been in vain.

I went back to the office and smiled awkwardly at Yun Duruo, now I don't look like a forensic doctor anymore, absentmindedly looking at the report of the last investigation from Mu Hanzhi's house, Yun Duruo is next to me looking at the transcript of the butcher's handling of this case twenty years ago.

A large number of photos are scattered on the table, although more than 20 years have passed, the photos taken at that time are exactly the same as the recently taken scene in Mu Hanzhi's home, except that the latest photos show the room covered in thick dust, and there is an indescribable desolation.

Repeated comparisons also yielded nothing, several days of staying up late made me a little exhausted, I fell asleep when the day was almost dawn, woke up almost ten o'clock, got up and had clothes fall on the ground, found that I was the only one left in the office, the clothes picked up from the ground were Yun Duruo's, I don't know when she left.

I was going to send her the clothes over, but Ling Guodong pushed the door open and handed me a report.

"This is a copy, the original has been handed over to the cloud team, the withered flower in the vase in Mu Hanzhi's room has been identified as a black mandala after laboratory testing!"

"Mandala?!" I asked curiously, frowning. "When did the flowers go in?"

"There should be a while from the extent that the flowers withered, but not too long, and the preliminary inference is that it should have been put in by the mysterious person who entered Mu Hanzhi's room." Ling Guodong replied very seriously.

"Why put a black mandala in a vase?" I said to myself.

"It's the language of flowers!" Chu Tianqi, who had just come in to change his clothes, said very calmly.

"Flower language?! What flower language? Ling Guodong and I asked in surprise.

"The flower language of the black mandala is revenge!" Chu Tianqi replied lightly while changing his clothes. "The other is unpredictable death!"

"It's a declaration of war! Also a provocation! Yun Duruo suddenly rushed in and put a picture in a vase in front of my eyes, which was the one I was looking at.

It seems that Yun Duruo also understood the meaning of the withered black mandala from the appraisal report, and I said thoughtfully.

"Revenge? But why did Liu Yuewu and Su Fengmei die, these two are Mu Hanzhi's closest people, from Liu Yuewu's conversation, he has brother and sister love for Mu Hanzhi, and Su Fengmei and her have mother-daughter love, what enmity do the two of them have with Mu Hanzhi? ”

"Liu Yuewu and Su Fengmei's deaths may be due to another reason, someone put the black mandala in Mu Hanzhi's room, judging from the meaning of the flower language, some people plan to avenge Mu Hanzhi, maybe the object of revenge is someone else." Yun Duruo replied worriedly.

"The apocalypse says that the black mandala flower language has another meaning, unpredictable death." Ling Guodong also said worriedly. "Judging from the deaths of Liu Yuewu and Su Fengmei, it is indeed incredible, which means that there may be people who will be implicated."

Yun Duruo subconsciously covered his nose with his hands, the windows in the room were closed all the time, I smoked all night, and the room had a very strong smell of smoke, and Chu Tianqi also realized that when he opened the window, the wind blew in, and the photos scattered on the table blew all over the place.

We hurriedly squatted down to pick up the photos scattered around, when I picked up a photo from the ground, I was suddenly stunned, this is a photo taken at the survey site twenty years ago, it is a photo of Mu Hanzhi's bedroom, I always feel a little strange, slowly stood up and walked back to the desk.

Searching through a large pile of chaotic photos, I found the photo of the withered flower that Ling Guodong gave me just now, and frowned even more tightly after comparing it.

"No one has been in that room since Mu Hanzhi committed suicide, and the last time someone went in was to take the photo album, but there was no trace of the scene being turned over, the only difference was."

I put two bedroom photos taken at different times in front of them and pointed to the vase.

"The person who went in later put this black mandala in the vase!"

"What's wrong?" Yun Duruo nodded and asked suspiciously. "What's wrong with that?"

I didn't answer her, and after rummaging through the messy drawer for a long time, I found the photo that Zhou Baiman handed us that day, the only photo of Mu Hanzhi we found.

"This photo was taken three days before Mu Hanzhi jumped off the building and committed suicide, and the location happened to be the bedroom, and the background is the same as the previous two, what is the difference between these three photos?"

Ling Guodong and Yun Duruo took the photo in my hand, and Chu Tianqi, who had always been calm, also surrounded him with some curiosity, and after they looked at it for a long time, Yun Duruo suddenly pointed to the photo that Zhou Baiman gave me and said loudly.

"It's a vase!"

"That's right! It's a vase, three days before Mu Hanzhi jumped off the building, there was a pair of delicate vases neatly placed on the wardrobe opposite the bedroom, but on the day Mu Hanzhi jumped to his death, in the photos of the scene exploration, there was only one vase left on the wardrobe! I nodded thoughtfully. That is to say, one of the vases disappeared before Mu Hanzhi died. ”

Or...... Or someone took it away! Yun Duruo said excitedly.

"When we were doing the verification of the sulfuric acid corrosion part on the rooftop before, we put forward an idea, if Mu Hanzhi did not commit suicide, but he killed her, then the roof where she jumped off the building was not the first scene." I nodded and walked back and forth a few steps, habitually pulling out my cigarette. "Mu Hanzhi has a withdrawn personality after having children, and he lives in a simple place and does not interact with people, if the roof is not the first scene, then what is the most suitable first scene?"

"Of course it's her home, Mu Hanzhi has very few people in contact with, and there aren't many places to go, the only place that can avoid sight is her home." Ling Guodong said very professionally.

I suddenly got up from my chair, picked up my clothes and said to Yun Duruo as I changed.

"You go to the butcher now and apply to re-do the scene investigation and appraisal of Mu Hanzhi's house at night."

"To Mu Hanzhi's family?!" Yun Duruo looked at me with some embarrassment, I understand her expression, the butcher has just finished teaching me and her, and the butcher firmly believes that Mu Hanzhi is suicide, and now he is still holding on to Mu Hanzhi is a little bent on going his own way, but Yun Duruo saw that my expression was firm and took a deep breath. "Okay, I'll apply right away, but why not now, but at night?"

"Brother Ling, I want to trouble you again tonight, you are an expert in identification, I'm afraid I want you to go there in person tonight." I didn't answer Du Ruoyun, but turned to Ling Guodong and said politely.

"Look at what you said, it's a good thing that you can really find out about your work, but we have done everything we should do to investigate Mu Hanzhi's house, and we have found everything that can be found, and I can tell you responsibly that there should be no omission." Ling Guodong said to me very calmly.

"Of course, I believe that there will be no omission in the survey and appraisal you are responsible for, but there is one less survey project!" I looked at him seriously.

"One item missing? What's missing? Ling Guodong asked in surprise.

"Bloodstain identification!"

"Bloodstains?!" Ling Guodong was stunned for a long time before he reacted, but he quickly nodded again. "There's really something missing."

Ling Guodong really can't be blamed for the omission of bloodstain identification, Mu Hanzhi's case was characterized as suicide twenty years ago, and no one would think about the so-called preconceived notions, but because of Yun Duruo's inference, if Mu Hanzhi was not a suicide, but a homicide, then her room was probably the only suitable murder scene.

I have looked through the records of the butcher's case back then, and there is no project about the bloodstain identification of Mu Hanzhi's room, and it is estimated that this process was also ignored back then.

I don't know how Yun Duruo said to the butcher, anyway, her face was ugly when she came out of the butcher's office, and when she saw me in the car, she said, you better pray that your reasoning is not wrong, otherwise you will come back and see the butcher yourself.

In fact, I don't have a bottom in my heart, everything is based on the level I imagined, but about the vanished vase, I always have some doubts, why the vase disappeared after Mu Hanzhi's death, and that vase is not a precious thing, the only possibility is that the vase is more or less related to Mu Hanzhi's death.

When he arrived at Mu Hanzhi's room, it was already dark, and Ling Guodong asked his colleagues in the forensic department not to turn on the lights and windows to keep the room dark, and then took out the luminol reagent.

Luminol is a synthetic organic compound, also known as luminous ammonia, which is mainly used for blood detection in modern forensic investigation, and the principle is that when testing blood stains, luminol reacts with heme and shows blue-green fluorescence.

This test is extremely sensitive, capable of detecting only one part per million of blood, even a small drop of blood into a large tank of water, and even blood stains that have been stored for many years.

Ling Guodong was very experienced in the door of a few drops to observe the reaction, there was no change in the dark, I heard Yun Duruo beside me a little rapid breathing, presumably she was as nervous as me now.

Ling Guodong began to drip luminol along the room step by step towards the bedroom, we followed him carefully to pay attention to any subtle color changes in the dark room, suddenly Ling Guodong stopped at a chair that was almost in the bedroom, he slowly stood up and looked at us, Yun Duruo and I looked at his flickering figure.

A little blue-green fluorescence slowly appeared in front of us in the dark, and I was secretly surprised in my heart, although it was only a little and it lasted for a short time, but the faint blue-green fluorescence was enough to convince me that there was a deeper secret hidden in this room, and that it had been hidden in the dust for twenty years.
