I'm very annoyed

  The atmosphere in the police station was very heavy, and the director's face looked terrible. There had been a series of murders in Qingcheng District under his jurisdiction, and the pressure on him was imaginable. As soon as Gao Cheng and I arrived, a meeting was immediately convened, and the forensic department gave a preliminary judgment: The time of death for both victims was between 2 and 3 am on Saturday. The female victim was identified by her family members and age estimation, and it was basically confirmed that she was Tong Ziqi, but further confirmation was needed through bone marrow DNA testing. Due to the severe burning of the body, it was impossible to determine how Tong Ziqi's left arm was severed, so it was temporarily determined as being cut off by a sharp object, but no murder weapon was found at the scene. There were two possible causes of death: bleeding to death after her arm was severed, or she did not die immediately after her arm was severed and was burned alive in the self-igniting car.

  The body was brought back and a forensic expert found a ring in his stomach, which was confirmed to be evidence of the Wu Yan case. An investigation has been launched into Tong Ziqi's relationships. As for the identity of the male corpse, no information has been obtained so far because there were no documents or mobile phone on him, and his face was severely damaged. Currently, an attempt is being made to restore his true appearance through skull reconstruction, and bone age testing revealed that the man was around 40 years old. The cause of death was as Gao Cheng said: he died from falling off a cliff, with multiple fractures in his skeleton. At the foot of the cliff, due to years of lack of sunlight, leaves accumulated and rotted, producing a special corrosive component, and there were also ants and other organisms, so the male corpse fell face down and died, with his face completely destroyed.

  However, neither of the two scenes found any favorable footprint evidence. Due to a rain, the ground was wet and the footprints on the cliff were destroyed by the hikers who discovered the body and reported it. There were no suspicious footprints around the male corpse at the bottom of the cliff.

  For now, this is all the information available for reference.

  Everyone's eyes turned to Gao Cheng, each with anticipation that he would give a more distinct and three-dimensional judgment. But Gao Cheng threw this hot potato back at me: "Let's hear my apprentice analyze it first."

  Speechless, I stared at him, without a single thought, what could I analyze? But he lowered his eyes, with an attitude of not caring.

  I awkwardly stood up and made my way to the stage, but when I got there, I didn't feel as nervous as I had initially. The eyes of the audience no longer intimidated me. After a brief pause, I began to speak: "I don't dare to make any arbitrary judgments about others, so I'll just talk about my own area of expertise..." After I finished explaining the details of the marks on the tree, there was a murmur of discussion from below.

  Regarding the extension of the mark from "lmk" to "l&k", I won't elaborate, as all the detectives present are experienced in handling cases and I believe there will be new directions for investigation later on.

  I took a glance at the high city below and cleared my throat again, drawing attention once more.

  "Also, there's another thing I think should be listed as a suspicious point: Tong Ziqi had an injury on her left foot and a broken left arm. Coincidentally, the male victim had prosthetic limbs on his left arm and left leg. There must be some connection between these."

  There are actually many doubts, was the Audi's self-ignition intentional or accidental? Why did Tong Ziqi want to drive up that mountain? And why did the middle-aged man fall off the cliff? Did they go up the mountain together or separately?

  Furthermore, is the person who left the mark the murderer or just a bystander like in the Wu Yan case? If it's the former, without mentioning the motive for the murder, how did he manage to do all this? He lured two people to the mountain and then committed the crime without leaving any clues. But if it's the latter, why did he appear at both scenes one after another? And what was the motive behind leaving the mark?

  L&K. The symbol "&" usually represents "and", so the focus is on the two letters "L" and "K". Excluding names and places, what could it be related to?

  Until the meeting was over, Gao Cheng didn't say a word. The director and others looked disappointed but couldn't say anything. It's also possible that they knew about Gao Cheng's strange temper, so when I was about to leave the conference room, the director stopped me and told me some things. When I walked out of the police station, I saw that person standing in the darkness, with the light shining on his body, casting a very long shadow.

  For some unknown reason, a sense of desolation emerged.

  Blinked, the illusion disappeared, because Gao Cheng had already turned around with a look of impatience and walked towards me.

  Several times I looked up at the sky, it was dark and didn't see any starlight, thick like ink. Still don't understand, Director Ming arranged a special car to send us, but this person beside me refused, and pulled me to walk on the cold night's main road, this is also okay, mainly he kept his face down from head to toe, his face was as stern as iron.

  I couldn't stand the low pressure and couldn't help but ask: "Are you tired?"

  I'm fine.

  Looking at him, he only gets particularly bad-tempered when he's hungry and tired. Today, running around all day, meals were just a casual affair, and now it's already past midnight, both of his taboos have been triggered.

  "I'm so annoyed." A sudden sentence popped up beside me, leaving me stunned. Just as I turned my head to look, he suddenly let go of my hand and walked a few steps ahead, leaving behind a dark silhouette. "Don't bother me for now, or I'll take it out on you."

  I stopped in my tracks and looked around. Gao Cheng noticed I wasn't following him and turned back to ask, "What's wrong?"

  "Take a look if there's a taxi, I'll take one back first, you calm down and sort out your thoughts." As soon as the words were spoken, a taxi really appeared in sight, just about to hail it, my line of sight was suddenly blocked. Gao Cheng stood in front of me with his eyes lowered: "I told you not to provoke me." I couldn't help but raise an eyebrow, is this considered provoking him?

  Then, out of nowhere, he suddenly reached out to me, aiming at the hair tie behind my head. With a light tug, my hair scattered open, and only then did he nod and say: "So that's it, it was missing this." He turned around again and threw off a sentence: "Don't tie your hair in the future."

  His long figure cast a shadow under the streetlight, and this time I didn't want to take a taxi away. Instead, I slowly followed behind him. It was vaguely clear that this was one of his thinking modes, he had sunk into a certain ideological realm and couldn't come out for the time being. Preliminary judgment was related to the case just now, as he said, finally met an opponent, so his reaction was also different from usual.

  The police station was not too far from the residential area, and after walking for nearly half an hour with Gao Cheng in front and behind, we arrived at the entrance of the residential area. The security guard looked out and glanced at us, his eyes lingering for two seconds before he walked out of the gatehouse, a defensive look on his face as he asked me, "Miss Xia, why are you back so late?"

  Based on the previous murder case in the neighborhood, the security guards were also extremely cautious. Especially for those who returned late at night, they would be strictly checked. Just as I hesitated and was about to respond, a cold voice suddenly came from beside me: "At 12:30 tonight, according to the duty roster, you should be patrolling inside the neighborhood. Dare I ask if this is another case of dereliction of duty?"

  The security guard's face suddenly turned red, stuttering and unable to speak. Gao Cheng let out a cold hum, pulled me towards the residential area, and when we reached the bottom of the building, I lightly coughed and said: "If you have a big temper, you can vent it elsewhere, others are not easy either."

  "Sprinkle on your body? Okay, you said that. Just now at the police station, you made a serious mistake. The female corpse's left arm was severed and her left leg was injured, which cannot be directly linked to the male corpse's prosthetic limb. Your argument will seriously mislead the direction of the investigation. Do you know why I don't make any psychological portraits for the murderer? Because there is insufficient evidence. Behavioral crime psychology is a professional and cautious discipline, all psychological portraits are based on evidence, which must be analyzed through summarizing various evidence after on-site investigation, and then modified bit by bit to form a behavioral psychological portrait."

  I didn't expect that a sentence of kind advice from me would be met with a string of words from him like a machine gun, leaving me stunned.

  At this time, the elevator door opened and he pulled me in with a big stride. After the elevator door closed, he continued to lecture: "In the previous case, I was able to give a rough portrait in the shortest time because first, I could see at a glance that the third and fourth people at the scene were not the murderers; second, there was already sufficient direct evidence to make a judgment. But this case is different - not only is there no direct evidence, but even circumstantial evidence doesn't hold up, and we haven't even investigated the victim's interpersonal relationships...

  The elevator arrived, the door opened, and Gao Cheng furrowed his brow in annoyance after being interrupted. He walked naturally to my doorstep, pulled out the key from his pocket, and tried to open the door. When it wouldn't budge, he turned around with a rare look of confusion and asked, "Why can't I open it?"

  I paused for a moment, walked over and pulled out the spare key from him, took out my own key from my pocket and inserted it, turning it while calmly saying: "The lock was changed a few days ago, your key doesn't work anymore."

  Her eyes flashed with a hint of coolness for an instant, but I pretended not to notice and walked into the house, picking up the shoe covers and throwing them on the floor: "Use these, so you don't get dirty and have to mop the floor." A dissatisfied voice came from behind: "Where are my slippers?"

  "Next door."

  After a brief pause, the sound of footsteps echoed loudly, and I knew he had come in wearing shoes without even turning my head. I let out a silent sigh, having no choice but to ignore it. Five minutes later, I brewed a pot of tea and came out, and Gao Cheng glanced over, "I want coffee." I asked quietly, "There are instant packets at home, do you want me to brew some?"

  "Can you drink it?" someone asked sarcastically.

  I turned around and brought two cups, pouring while saying: "Then let's drink my Longjing tea."

  "Your washing technique is incorrect."

  I paused for a moment, without lifting my head, and replied: "It's already late at night, just make do with it. If you really don't like drinking tea, there's a water dispenser over there, you can drink plain water." After half a moment, that slender white hand reached out and took away a cup of tea.

  Gao Cheng took a sip of tea and leaned back in his chair, saying, "Go ahead and ask whatever you want to ask."
