Black......

It's dark......

It was pitch black in front of him, but Lin Kun could still roughly judge his current situation-

Sitting on an iron stool with a backrest, his eyes covered by a thick blindfold, his hands behind his back, locked by cold handcuffs, his legs tied to the legs of the stool, it was extremely difficult to even move.

First of all, you have to get out of trouble, and it's not a good feeling to be tied up like this.

He hadn't tried to flip from side to side until he knew where he was, maybe he was on the edge of the floor or something.

Since he knew that his every move was under surveillance, of course Lin Kun would not ask No. 1 for help.

If you have to cheat on a detective exam, you can't help but look down on him.

Since his last injury was healed, Lin Kun has accepted a few more commissions with a lot of oil and water, earning tens of thousands of yuan.

But he knew very well that after being silent for a month and not solving any major cases, his popularity gradually decreased.

If you don't think about it, you may soon face the grim situation of not being able to find a commission.

After you have the money, of course, you must get this detective certificate as soon as possible, and this thing is still very important.

Nowadays, 90% of the detectives on the market are not formal detectives, and even if they have solved some cases, they will not make a lot of money, which is very different from regular detectives.

It's not that these people don't want to become official detectives, it's that the detective exam is too difficult, and this thing is not like relying on a driver's license, and the chance of passing without real skills is extremely low.

10,000 registration fees, once you fail, the next time you want to take the exam, you have to pay 10,000 registration fees, and people who don't have anything real to take the exam are simply sending money.

However, once it is passed and becomes an official detective, the commission fee will naturally rise, and the fee will be at least ten times more than those of those wild roads.

There are two types of detective exams, one is the written test, which is to make papers, and you can pass the assessment if you can achieve a certain score.

It sounds simple, but the questions on the paper are probably not even incomprehensible to ordinary people.

Moreover, there is no fixed range of exam questions, and each exam is a brand new question issued by a senior tutor, which tests logical thinking ability and reasoning ability, and it is completely impossible to pass the exam by rote memorization.

The second is a real-life test, which is what Lin Kun is doing now, taking him to a place where the puzzles have been arranged in advance.

If he can successfully solve the final puzzle, there will be no suspense and he will pass the assessment directly.

His every move will be monitored and watched by three professional tutors.

Even if Lin Kun can't solve the final puzzle, as long as two of the mentors think he is qualified, he can still become an official detective.

When his thoughts returned, Lin Kun twisted his head, feeling that there seemed to be a thread on his neck.

He turned his head and saw that the thread seemed to be wrapped around his head.

After thinking about it, he shook his head, straightened his chest and tilted his head, and the thread slid all the way down his back.

A moment later, Lin Kun's handcuffed hands grabbed the thread, and after a few pulls, he ripped off the blindfold.

With the light restored in front of him, Lin Kun was able to take a closer look around.

It looked like a utility room, with little space, no windows, just a locked front door.

He was in the center, with a dim yellow light bulb hanging above his head, and a five-tiered display case on the left and right of the house, with some miscellaneous items.

Lin Kun turned his head and looked at the handcuffs behind him that were cuffing his hands, the silver-white handcuffs looked quite cold and strong.

In the connecting part of the handcuffs, there is no keyhole, and there is a turntable-style combination lock with a four-digit password.

Lin Kun turned his head and looked down at the chain that tied his legs, it was actually a turntable-type combination lock, which was also a four-digit one.

The passwords of the two locks can't be the same, otherwise they will be meaningless, so what Lin Kun needs to find now is two four-digit passwords.

Judging from the current situation, his final puzzle should be to get out or escape, anyway, it must be no problem to unlock the lock on his body first.

The two passwords should be hidden in this room, Lin Kun looked around left and right, and finally fixed his gaze on the first layer of the display case on the right.

There was a doll the size of a baby's arm.

The doll holds two hands aloft, two fingers on the left hand, the index finger and middle finger, and three fingers on the right hand, the thumb, ring finger and little finger.

Second from left, third from right.

Lin Kun thought for a moment and looked at the second floor of the display case on the left, where a chopstick was placed.

He turned his head to look at the third floor of the display case on the right, where three chopsticks were placed.

Then he shifted his gaze to the first level of the display case on the left, where a pair of mutilated gloves were placed.

The left glove is missing a middle finger and the right glove is missing a little finger.

If the fingers are sorted, the thumb is the first, and the middle finger and little finger represent 3 and 5 respectively.

Third from left, fifth from right.

There are 2 small bowls on the third floor of the display case on the left, and 3 small bowls on the fifth floor of the display case on the right.

The first layer on both sides is related to the hand, and presumably the code to unlock the handcuffs is on this doll and this glove.

Nowadays, four numbers are obtained by the number of chopsticks and bowls, 1, 3, 2, 3, but it should not be as simple as the number of chopsticks and bowls is the unlocking code.

Bowls and chopsticks are most likely to be associated with eating, the doll on the right and the gloves on the left can be counted as a person, and ordinary people only need a pair of chopsticks and a bowl to eat.

The doll on the right corresponds to a total of 4 chopsticks, and the glove on the left corresponds to a total of 5 bowls.

So the doll on the right has two more chopsticks and one less bowl, and the glove on the left has two fewer chopsticks and four more bowls.

For ordinary people, chopsticks represent the right hand, and the bowl represents the left hand, and then the number is divided into the left and right hands.

The doll has two fingers on its left hand, but it is missing a bowl, so it needs to be subtracted by 1 to get the first number of 1.

The right hand has three thumbs up, but there are two more chopsticks, so you need to add 2, and the second number you get is 5.

In the same way, the left hand of the glove is only missing a middle finger, which is actually four fingers vertically, but there are four more bowls, so you need to subtract 4 to get the third number of 0.

The right hand is missing a little thumb, and it also has four fingers vertically, but two chopsticks are missing, so it needs to be subtracted by 2, so the fourth number obtained is 2.

1、5、0、2！

Lin Kun arched his fingers, and with difficulty dialed the wheel of the handcuff combination lock, and entered the four numbers.

"Click!"

With a crisp sound, the handcuffs popped off automatically, Lin Kun's hands finally regained their freedom, he rubbed his wrists, and said to himself: "The most basic logical reasoning, when used as an appetizer, is indeed quite passable."
