Detective Training Manual

　　 Zhou Yan frowned.

For this question, the answer is 1x7=7, which is correct in theory.

　　 But it seems a bit flawed.

　　Because the 1x1 matchstick drawn on the title is very close, if it is only on top of 1, and a matchstick becomes 7, then the matchstick will be on top of x.

　　 This is not true in terms of space.

　　Emmm...It should not be that simple.

　　 Zhou Yan turned out the book.

　　【Zhou Yanta █: Change four to 1/1】

　　 Zhou Yan shook his head: No, so the ratio between the numbers is wrong and not perfect.

　　Also, why did this black frame come out again?

　　 [Mr. Qin is a dream: an inequality 1+1≠7 can be established]

　　 "It's not right, people say that it is an equation, but it has to be an inequality. Isn't it a direct change to the question."

　　 [Black cat by the corridor: 1×7=7? 】

　　 This answer is the same as Zhou Yan thought at the beginning, but it is unreasonable in terms of space. It might as well be written as 7x1.

　　 However, the huge multiplication sign between the numbers always makes Zhou Yan feel a little tedious.

　　 It may be because the text in the book is delayed, so there are not many people who leave a message, and in these few comments, Zhou Yan did not see an answer that he could affirm.

　　 So he closed the book.

　　 When taking an exam, plagiarism is naturally easy.

　　 But plagiarism doesn't mean it won't, it's just lazy thinking.

　　 Zhou Yan picked up the test paper and stared at the matchsticks without blinking.

　　 ten seconds later——

　　 Hmm, I thought of it.

　　 He picked up the pen and wrote on the bottom

　　Ⅸ=9

　　 This time, whether it is space or location, it seems very appropriate.

　　 Of course, to be on the safe side, the answer of 7x1=7 is also written in Zhou Yan.

　　 It is the first time to help the boss, so he has to be more stable no matter what.

　　 Zhou Yan is very satisfied with his answer.

　　 Then I started to look at the next question.

　　......

　　 There is a little more text in this question.

　　——————————————

　　 One night, a programmer was killed in front of the computer.

　　The cause of death was that a knife penetrated the liver and died of excessive blood loss.

　　 Before he died, the programmer's fingers happened to be able to touch the last row of buttons on the numeric keypad. Fortunately, his fingers could barely move.

　　 So, he typed the following series of numbers on the screen.

　　1111011

　　1110111

　　1000001

　　1011101

　　1000001

　　1011101

　　1000001

　　1111111

　　 After police investigation, four suspects were identified.

　　 Little Red, Little Lan, Little White, Little Green.

　　Who is the murderer?

　　——————————————

　　 "Heh." Zhou Yan not only smiled. Although these questions are simple, they are really interesting.

　　 He flipped through the book and found that the person in the book had not yet given the answer to this question, probably because of the signal delay.

　　 "Why don't you...take a test of the person in the book?" He thought very horribly funny.

The name of the book in hand is "Manual for the Practice of Famous Detectives", and now I seem to have finally embarked on the path of a detective, but I don’t know how far the people in the book and their path of detection have been .

　　 Will it not even be able to solve such a simple question?

　　 "Hey hey~" Zhou Yan smiled maliciously, and then put the question aside without even writing the answer.

　　 He is going to wait a while to see what the people in the book can do.

　　 Then, the next question.

　　——————————————

　　 The billionaire took a private helicopter to his villa for vacation, but an hour later, the helicopter returned to the airport.

　　 The pilot reported to the police that the rich man suddenly opened the door of the plane and jumped to commit suicide while he was flying. He also left a suicide note on the chair.

　　 The police immediately contacted the detective and went to the helicopter to investigate.

　　 Sure enough, I found that everything was just as the driver said. There was indeed a suicide note on the chair where the rich man was sitting. The content indicated that he was tired of life, so he committed suicide and had nothing to do with others.

　　 But the detective immediately asked the police to arrest the driver. He believed that the driver was suspected of murder.

　　 Why did the detective come to such a conclusion?

　　——————————————

　　 This question is also very simple.

　　The purpose should be to test the detective's mastery of the testimony.

　　 A qualified detective must concentrate completely when listening to the testimony of the suspect. The loophole in a piece of testimony may be fleeting, and the detective must keenly catch the loophole at the moment it appears ~www.readwn.com~, otherwise, it will leave a chance for the murderer.

　　 And for this question, Zhou Yan naturally did not write the answer. After all, he wanted to make it difficult for the famous detectives in the book.

　　 So his eyes fell directly on the next question.

　　The topic is...

　　——————————————

　　Luxury passenger ship sails at sea.

　　 One morning, a body was found on the deck.

　　 The deceased was a rich man who was stabbed to death by a dagger.

　　Because the crime happened in the vast ocean, the murderer must still be on board.

　　 There are three people on the boat who have motives for killing.

　　Suspect A—the victim’s nephew, who is the heir to his property, is in debt due to gambling and is suffering from being unable to repay.

　　Suspect B, the victim’s secretary, was fired because of corruption during a voyage trip.

　　Suspect C—The wife of the victim, because she is about to divorce, she has a grudge against the suspect.

　　 Based on the above situation, from the perspective of the motive of the murder, please judge who the murderer is more likely to be?

　　——————————————

　　 The purpose of this question is even clearer, which is to examine the detective's ability to explore the motives of the case.

　　 A qualified detective is naturally impossible to bump into the case like a headless fly, and the motive is to guide the detective in a direction.

　　 It can be said that the motive of the investigation is the most important and the first thing to be done in most cases.

　　 Zhou Yan stretched his waist, and then picked up the detective note on the side.

　　 This is just the beginning, so I can’t sit still...

　　A famous detective has a long way to go.
