Lin Xi, who was beside him, opened his eyes when he saw Zhou Yan, and smiled as if he had known this:

"What, I thought of it?"

"Yes!" Zhou Yan's words are full of power!

"The answer is... tires!" His tone was raised a little:

It's the big tires on the truck.

It's better to be two!

The specific operation is also very simple, that is, put a set of safe in and one on both sides.

Because the thief obviously went to the safe, he probably saw the scene of a worker carrying the safe while moving, so he became interested in seeing money.

Now that you know the size of the safe, it is easy to find the size of the tires you pair with.

After carding the safe, plug the gaps between the edges and corners with clothes or the like.

Then, what the thief has to do is not move the safe, but put it in, and it is enough.

When you roll to the stairs and let go, the safe will automatically roll down. The length of a stairs is only more than four meters. Even if you hit the wall, it will not make too loud noises due to the shock absorption of the tires!

The speed is faster than that of a person, 16 floors, more than 10 minutes are enough!

Zhou Yan’s words are just a complete and straight word.

We have to understand, after all, it involves salary and lunch, no matter who it is, we have to be a little excited!

Lin Xi looked at Zhou Yan's attitude and nodded with a smile.

"Yeah, it's just the tire."

"Hahaha—————" Zhou Yan laughed and said: I want to stump me. I underestimate my Detective Zhou's wisdom. I will pay now, salary, bonus, lunch, hehe, I will accept it all~"

Zhou Yanzheng said as if he was successful.

Unexpectedly, Lin Xi raised his cell phone calmly.

I saw that there was a timer on the screen of the mobile phone, and the time on the timer was 5 minutes and 20 seconds.

Sorry, you are talking too much nonsense. As of now, it is five minutes and twenty seconds. If you throw away the last nonsense you used to brag, it is five minutes and five seconds.

"Ah?" Zhou Yan was stunned: "Zero...zero five seconds?"

"Yes~" Lin Xi said: "So, you lost."

"But... the time I waste in speaking should not be counted. After all, I already knew the answer to the puzzle before I spoke!"

"Ha." Lin Xi smiled and said, "What are you thinking? When you were a child, you had to finish the answers before you could count the score? Did you hand in the blank paper and go to argue with the teacher, saying that you already knew the answer, but you didn't have time to write it?"

"But... this is different from the exam, right?" Zhou Yan shouted.

But Lin Xi had completely ignored Zhou Yan. She smiled and turned around: "Mr. Zhang, we have solved this commission for you. I wonder if you are still satisfied?"

"Hahaha--" the old man smiled and said, "Satisfied... very satisfied. Thanks to you, this safe has almost become my heart disease in the past few months!"

"Well, it's good that Mr. Zhang is satisfied. So, the question about the entrusted fund..."

"Okay, just like we said before, no point will be reduced!" The old man seemed very happy, and hesitated and agreed to pay the remuneration directly.

After that... after a brief greeting, Lin Xi and Zhou Yan left the apartment.

The commission was successfully completed!

Before walking out of the apartment, Zhou Yan found that the old man did not leave. Instead, he stood alone in the apartment, facing the window and looking out the window.

Zhou Yan couldn't see the old man's expression, but from this back, he could feel an indescribable loneliness.

What is it that an elderly man wasted so much property and bought an old apartment that had been around for 40 years?

Is it really just because of a mystery?

If it's just because of a puzzle, then you don't have to buy it at all.

Will his family really not object to such childish behavior?

Or...this old man has no family anymore.

What is his concern alone in a city without relatives?

An unsolved puzzle is the place where you once grew up.

This kind of problem is definitely impossible to solve with Zhou Yan's age.

At the last moment he walked down the stairs, he saw the old man's heel.

There are traces of repaired on that shoe heel...

At this moment, Zhou Yan seemed to think that the old man might not be so rich. He took out all his property and bought the apartment, but might just be like a child who would act willful.

He...just to have something to remember.

......

Downstairs of the apartment, there are traffic.

Zhou Yan and Lin Xi walked towards the detective office.

Because Lin Xi was cheating, Zhou Yan ignored her and flipped the notes in her hand.

From time to time, I can still remember the old man's slightly sad back.

Well, that is someone else's life, and I am just a passerby in his life.

Looking at this note again, just now, because time was tight, Zhou Yan didn't take any time to read it. Now it seems that someone in the notes thought of the method of using the tire to block the safe and pulling down the wheel.

[Panda at Jiajia: Did you use any shock-proof and ordinary materials? Is kraft paper suitable?]

Well... this brother didn't guess, but he had already guessed the shock absorption. I guess he could guess it even if he thought about it again.

[Breathing - Yasuo: It's a tire. The truck has hollow tires (or spare tires). Put the safe into the tire and roll it down within 10 minutes. Because the tires are shock-proof, they should not be heard. Get it done in a place where no one is there and leave from the highway.]

"This man seemed to be the same as he thought, but this brother had never driven a truck at first glance, because he obviously didn't know how thick the truck's tires were.

A household safe has an average height of about 65 cm, while a truck's tire has a thickness of 19-20.5 cm.

Then let's round it up, even if it's 20 cm.

You put two 20 cm tires on a safe. Believe me, the safe will definitely be covered tightly for you. If you do it more accurately and cover two plastic wheel plates on both sides of the tire, unless someone comes to peel off the tire, he will not be able to see what is inside.

In other words, you probably don’t have to find a place where no one is done, just wheel it on the car and run away with one foot of the accelerator."

As he looked, Zhou Yan also saw some negative comments.

For example, the following brother.

[Fu Tianqi: Don't be a tire. I feel that the tire is not as operable as a sled.

I have personally worked in infrastructure. If the material contact surface of sleds is small, there will only be a whisper, and it can be operated very conveniently by one person.

If the tire is 200 kilograms of gravity acceleration, you can't fuck a single person. The noise generated by hitting the wall when falling is enough to blow up all the people in this building.]

"Emmmm...Brother, do you really think that the sled only has a squeak, and the sound of the tires can blow everyone in the building out?

Let’s not talk about sleds, just talk about the loud sound of tires... the company that produces tires is about to go bankrupt.

Otherwise, those cars on the curbs and the like will not be like setting off firecrackers.”

However, this idea also gives Zhou Yan a little warning.

That is, he really doesn't know what it feels like to slide down the stairs.

Because he had never seen it before.

And this brother obviously has experienced this kind of scene.

In other words, the thief might be able to use a sled. So, this kind of puzzle may not be the only answer.

But it doesn't matter. After all, the knot in the old man's heart has been untied, and this is the most important thing.

Lin Xi looked at Zhou Yan ignoring him and was flipping through books, and couldn't help but smile.

"Why, I think I'm cheating?"

Zhou Yan knocked the book down, and didn't care that the other party was his boss, so he started walking with her while discussing how to calculate his lunch money!

Under Zhou Yan's words of 3 inches, Lin Xi finally gave in. She said that he lost half of the bet, and his salary would not be deducted, but she didn't care about it this month.

Zhou Yan felt very distressed, but he couldn't deal with Lin Xi for the time being and didn't dare to take action, so he had to admit defeat in disappointment.

Back at the detective agency, Zhou Yan sat on his sofa angrily!

Lin Xi smiled and personally made a cup of coffee for Zhou Yan...

"It seems that Detective Zhou is not satisfied?"

"Of course, you are obviously deducting employees. I still think that you are different from those capitalist bosses~" Zhou Yan shouted directly.

"Haha, be glad, no one in the entire city except me would hire you, a person who doesn't even have the qualifications to be a detective! And...what does capitalism mean?"

"Uh..." Zhou Yan was speechless for a moment.

Has the word "capitalism" not developed after the world was unified?
