Case 1: The Unseen Murderer\Luo Kang was a fitness coach at a certain gym. He was strong and physically fit, and his family was relatively well-off, but recently he had been experiencing dizziness, nausea, and a racing heartbeat. Even after visiting the hospital for check-ups, nothing could be conclusively diagnosed, so he had to recuperate at home.\One day, as usual, after taking his sedatives, Luo Kang was preparing to take a nap when suddenly the phone rang. Luo Kang answered, only to hear a voice extremely hoarse say, "Three days. Within three days, bring 3 million to a certain warehouse in Area A, or else you die!"\Luo Kang immediately hung up, thinking it was a prank from a friend, and he really wasn't in the mood for such a joke. But the phone rang again persistently.\"Listen, whoever you are, don't ever call me like this again! Otherwise, don't blame me for getting angry!" Luo Kang was starting to get furious. Ever since he had this strange illness, he, normally a good-natured person, could no longer control his emotions.\"Luo Kang, right? Don't worry, you've never added me. Are you experiencing tinnitus, vomiting, blurred vision now? Losing your mind, right? It's okay, this is just the beginning. I already know everything about you—your family, friends, wife, even your little affairs at the gym, all the things you don't want the world to see. Hmph, if you want these things not to be exposed, if you want to survive, 3 million. I want to see the money within three days, or else... die!!!!!!" The voice on the other end was still hoarse. Before Luo Kang could get angry, the line had already been hung up.\Who is this person? How could they know these things? I've never seen them? Why threaten me? Luo Kang realized that he was inexplicably being blackmailed by someone he had never met, and this person seemed to know everything about him.\However, Luo Kang never had the chance to figure this out. Three days later, Luo Kang was dead, in his own room, a locked room, leaving behind no criminal evidence.\Because Luo Kang had reported the case in advance, the police learned part of the situation during the investigation and identified several basic suspects.\A. Luo Kang's wife, because Luo Kang had affairs with multiple women at the gym, she might have murderous intent.\B. Luo Kang's psychologist, who was the victim's most trusted person, and whose wife was also having an affair with the victim.\C. Luo Kang's debtor, who owed Luo Kang 300,000 and had not yet repaid it.D. Luo Kang's lover, after seeing Luo Kang's true character, carried out extortion and revenge, and ultimately committed murder. But the biggest question is, what method did the criminal use to learn so much about the victim's privacy, and what method did they use to kill the victim in a completely sealed room? Several technical backbones from a drilling company lived upstairs from Luo Kang. They had just moved in and said that after midnight every day, there would be some abnormal sounds coming from Luo Kang's balcony. Since they had never seen Luo Kang, they did not interfere. Now, if you are at the crime scene, how would you reason and identify the real culprit?
Case 2: Interview
I am a female journalist, assigned to conduct an exclusive interview at the residence of a mysterious nutritionist. Why call him mysterious? Because he could be considered the most respected figure in the entire nutrition field, yet he has never appeared in public. He only publishes articles, and no one has ever seen his true appearance. I was fortunate to meet him. His warm smile was very likable, and surprisingly, he was so young, around 40 years old. Looking at his articles, I would have thought he was an elderly man around 80.
"Shall we start the interview now?" I asked.
"No rush, it's mealtime now. How about we start after eating?" he said with a smile, which was truly charming.
Yes, turtle soup, clears heat and nourishes yin, calms the liver and extinguishes wind; fresh mushroom with tender meat, fragrant and tender, ecological diet; stir-fried celery, lowers blood pressure, relaxes muscles and promotes circulation; and longan yam cake, very effective for insomnia. Ah, I was actually fortunate to eat the meals prepared by this master himself... But I still felt something was off.
This journalist never returned to the newsroom; she died, stabbed in the heart during the meal.
What did she discover?
Who killed her?
Case 3: The Missing Gold
1.5 tons of gold were stolen about half a year ago. The police still have no leads on the case. Because each thief at the crime scene was masked, they are currently relying on facial reconstruction technology to grasp the general appearance of the criminals. It is known that the large truck used by the criminals to steal the gold was found in the suburbs, abandoned, and there were no other clues.
"They would never flaunt such a huge amount of gold in public. They must hide and transfer the gold. Do not let any vehicles escape!"The detective roared inside the station. This case had made it impossible for him to suppress his composure. He knew that stealing gold might require a team, but transferring gold alone would be enough, making the target even smaller. Finally, the investigation team locked onto and intercepted three targets. They looked similar to the criminals who had been reconstructed, and all planned to leave the city tonight. It should be noted that once they left the city, the criminals could carry their huge fortunes and get away with justice. 1. The suspect was driving his own car, preparing to leave the city to visit relatives. 2. The suspect was driving a large truck delivering goods. 3. The suspect had arrived by passenger transport from City A and was now returning to the city by air. The problem is, the suspect only resembles the restored portrait, nothing else—not even the gold in the car can be found. You only get one chance; missing it would be a loss for the public. Years of experience tell the detective suspect is among them, but where's the gold? Where exactly is it? Case 4: Last Words
By the time they arrived, Jack was already dead, holding a pistol. There was no bullet in the gun, because the only bullet was inside Jack's skull. Jack's hand was still in the trigger, blood splattering all over the wall. "Was it suicide?" I muttered to myself. On Jack's desk was a tape recorder. When I saw it, I couldn't help but press it...... "Matt said he'd come tonight, what should I do? I'm not mentally prepared yet. I used all the money he gave me to trade stocks, and I lost everything! I lost everything! What am I supposed to give him back? ...... No! No, I can't face him! He'll kill me! He'll kill me in the cruelest way! I...... Me...... Right! All of this is my fault! I should have ended my own life!! Matt was right! I was wrong! I was wrong! "It was Jack's voice, very urgent. Isn't it normal for people to face the things they least want to face?" The recording ended with a gunshot, then went blank. I turned off the recording, and the answer was already clear... I see. So, what's the answer?
Case 5: Suspicious
The five-year-old girl lay there, in the ditch behind the welfare station's restroom. Her skin was as tender and white as newborn, as if still alive, but her small intestine was torn and dragged out, her uterus detached, and her genitals were severely torn and marked by blunt force insertion—a horrific sight.Nearby, some toilet paper was scattered, along with a suspected murder weapon, and a knife—cold and sharp.
Pedophile rape! That's right! People like this definitely deserve to die! The police immediately launched a manhunt and quickly identified four suspects, including Jiang Tao.
The polygraph test showed Jiang Tao was lying, so he was soon sentenced for rape and intentional homicide. He was imprisoned as a suspect for rape and intentional homicide. Jiang Tao said nothing; no one knew how the case was interrogated. Within a day, the relevant authorities made Jiang Tao hand over his confession. Evidence indicated that the two bloodstains on Jiang Tao's body belonged to the victim, proving contact with him. Liquid substances on the toilet paper were found in the DNA test, indicating Jiang Tao's identity. The time of discovery of the victim was 15:20, and Jiang Tao was the first to find him. Before 2 p.m., Jiang Tao had no alibi evidence and had plenty of time to kill. In the end, Jiang Tao was executed by firing squad, already in a dazed state of mind, with a strong and powerful signature on his confession. He was ultimately scorned and infamous for generations. The case occurred in 1992, a major wrongful conviction. The murderer was caught in 2000 while committing another crime in Taipei. A wrong judgment led to the loss of another life. We can speculate, but mistakes are absolutely not allowed! If you were the judge involved, how would you use evidence? to uncover doubts and bring the truth to light?
. Case 6: Vanished Without a Trace
The lady of the villa lost her diamond ring, and there are two suspects: one a maid and one a male servant.
Because the diamond ring is expensive, the lady installed a timer camera in a hidden spot nearby, and the two of them appeared in the photo at just the right moment.
There are four photos in total.
The first photo shows the male servant staring at the diamond ring.
The second photo shows the male servant leaving the room, with the diamond ring still there.
The third photo shows the maid leaving the room after cleaning; the diamond ring is still there.
The fourth photo shows the maid and male maid together discovering the missing diamond ring.
The presumed condition holds. Who stole the diamond ring?
Case 7: Dog
He likes walking dogs, growing flowers, and eating chocolate. He's an extreme person, so I tried to speed up my pace. However, when I arrived, he was already dead, and his dog was dead beside him.\He is my friend. Recently, he often complained to me about his troubled relationships and work. That's right, suicide—he wanted to kill himself, and now he really did it. He died on his bed, with an entire empty bottle of sleeping pills beside him. His right hand was empty, as if he had been holding something before he died; it should be the sleeping pills. The body was still warm, so the death seems to have occurred within an hour... I was guessing recklessly.\“Or maybe... it was too late?”\Hearing the voice, it seemed to be Johnson. This guy, didn't he just have a fight with him a few days ago over bankruptcy issues? What is he doing coming here now?\“Tsk tsk, don't suspect me. Didn't you see I just arrived? And forty minutes ago, I was still out talking business with a friend. He invited me, saying he wanted to have a proper talk with me. That's why I came. Even rushing here took about 20 minutes. Achoo.” Johnson said in a flattering tone, then sneezed.\Winter is really cold. Is it because he knew he was going to die, so he didn't use the electric blanket? Poor guy.\No! I seem to have realized something. “So that's how it is...”\I turned around and said coldly to Johnson: “You bastard, you came to confirm whether he was dead, didn't you? Afraid of that fatal evidence?”
Answer to be revealed later!
(Doudou - Reasoning) Reasoning Emperor is here, with a large number of reasoning questions to develop your thinking.

First, I basically believe the killer is his psychologist, but I still don't know exactly how the murder was carried out.
The fourth is that Jack owes money to others, then lost it all in the stock market, and, not wanting others to treat him cruelly, committed suicide?
The last one definitely wasn't caused by sleeping pills; it was related to the electric blanket and the dog. The killer was Johnson. He killed the victim, but the dog saw it and held onto him tightly, and was eventually beaten to death as well. He used the electric blanket to raise the body temperature so that the estimated time of death would be postponed. But how did he kill the victim, and how did he pull the plug of the electric blanket afterwards under such circumstances?
The first question is B. He knows Luokang very well, so choose A and B. Strange noises on the balcony indicate that an outsider came, so eliminate A. According to the technician upstairs who does drilling, the strange noise indicates it might be sound or shock waves that killed him. The shock waves or sound are close to the frequency of the heartbeat, so...
Damn it! Too slow, it's just a game, don't you dare compete with me, I'll go look at something else right away.
Passing by, Qian also joined in to play. By the way, I feel that the information given in the first question is definitely incomplete, and we cannot determine who the murderer is. We can only see that the murder weapon is sound, and we cannot rule out factors like lying and high-tech methods of killing. Personally, I think it was someone from the drilling company, because if it were a group of criminals and high-level technology, it would be impossible to state during the ransom that Luo Kang would die three days later. This kind of skill, predicting the time of death, is basically impossible for a psychologist and the other suspects, so we can directly rule them out. Also, Qian still thinks that the information given by the original poster for the first question is incomplete.
The case is the third one. When the passengers came, it was a gang that was transported, and now it is focused on these gangs.
Question 2 Qian thinks that the dishes this nutritionist served to the reporter were completely wrong, so this person must be fake; otherwise, it would be impossible for someone considered a top authority in the field of nutrition. It should be that this person ended up killing the real nutritionist and didn't expect it, but when the real nutritionist had an appointment with the reporter, they initially planned to get by unnoticed, but the reporter found out, so they ended up killing together. (Originally a combination meant to clear heat, made into a longan and yam cake—aren't you worried about it causing internal heat?)
Case six: timed photography, with intervals. After the male servant left, the female servant came in to clean. She may have discovered the camera and then saw the photos, realizing that the male servant had been there and noticed the gaps. So she left after the camera took the third photo and then came back to retrieve it.
