"Two...two sentences!" replied the checkout, "Checkout, I will reward you... the rest of the answers are nodding or shaking your head..."

"Checkout" is the first sentence, and "I'll reward you" is the last sentence.

"Have he ever had any strange actions?" Fang Buwei asked again.

The checkout shaking his head.

...

Gao Sizhong has repeatedly reviewed these questions and details, and Fang Buwei just wanted to confirm whether the checkout clerk had any problems.

The checkout officer's behavior is normal.

There is no problem with the checkout staff. During this period, Zhao Yulin only contacted the drivers of He Shili and the Young Marshal's special car.

There will be no problem with these two people.

"After Zhao Yulin left, has anyone entered the room?" Fang Buwei asked unwillingly.

"No!" Gao Sizhong replied, "The floor where he lives is ours, even the ones responsible for cleaning are ours. Not to mention people, I know a male and female when I enter..."

"Where is the corridor? Have you checked it?" Fang Buwei asked again.

"I've checked it a long time ago, and I don't even have a hair... and since he left the room, he was in our sight, and I didn't notice that he had any abnormal movements... Oh, except for the time when you ordered the secret whistle in the hall to evacuate." Gao Sizhong said again.

My eyes never left Zhao Yulin.

Have you seen a ghost?

Fang Buwei cursed secretly.

Zhao Yulin can send instructions under his nose, but there are really not many ways to use.

Even if you use knocking on the table to send passwords, you will never escape your eyes.

I must have neglected something.

Fang Buwei looked at the things on the table again.

There is a copy of Zhao Yulin's bill statement, a tip for the checkout officer, a note book and two note papers with words written on it.

These are all things Zhao Yulin had come into contact with when checking out.

The bill is handwritten, with neat handwriting, simple and detailed.

Apart from the room fee, there is only the meal fee, but I remember every meal every day.

Those two bad tickets are fine, a total of 70 cents. The promissory notes of the central bank's silver dollar are clean, without any handwriting or scratches.

Fang Buwei picked up the note book again.

Looking at the location of the seam, there are obvious tearing marks.

"What's the purpose of this? Leave a message, a note letter?" Fang Buwei asked Gao Sizhong.

"Absolutely!" Gao Sizhong replied, "There are also customers who use this to settle accounts..."

"Did Zhao Yulin use it too?" Fang Buwei narrowed his eyes suddenly.

"The checkout officer said he used the paper on it to settle the house account..." Gao Sizhong replied.

"Which page is the account that was calculated?" Fang Buwei asked the checkout officer.

"The customer tore it off and took it away with the bill roll..." the checkout officer replied.

Fang Buwei recalled a little. Zhao Yulin did put things in his suit pocket. He only thought that Zhao Yulin was carrying the money that the checkout officer asked him.

Some customers will check whether the hotel's accounts are correct, and some customers who are not the boss will avoid going back to reimburse the reimbursement and take back the checked straw paper and the bill.

But Zhao Yulin would not do such a thing.

Who did he ask for reimbursement?

Kanto Army Secret Service?

It can make people laugh.

"How many people have used sticky notes?" Fang Buwei asked sternly, and at the same time he lifted the sticky notes to the position where they could shine in the sun, looking at the traces on the top page.

"I expected it long ago!" Gao Sizhong pointed to the sticky notes next to him with pride. "After Zhao Yulin, the accountant who went to this position to settle the bill was an accountant from the General Affairs Office of the Ministry of Education. These pages were the papers he calculated the accounts, and the person was also locked next door, so there was no problem..."

Fang Buwei picked up the notes and took a look.

The handwriting is dense, so where can you tell if there were any marks on it before writing?

Fang Buwei couldn't figure it out. What reason did Zhao Yulin have to calculate the details? There must be problems with this note book.

He ignored Gao Sizhong and started to look through page by page.

When he turned to the middle, Fang Buwei discovered something strange.

There are marks on one page, which are obviously left after the words written on the previous page, but the previous page is clean.

Fang Buwei opened the gap between the line between the note book and saw traces of tearing.

He glared at Gao Sizhong and said coldly: "Pencil!"

Gao Sizhong couldn't see that something was wrong. He took a pencil and handed it to Fang Buwei in disappointment.

Fang Buwei held the dagger and quickly scraped the refill core. In a few seconds, the page with marks was covered with toner.

"Can you do it?" Zhao Shirui asked.

"Try it and talk about it!" Fang Buwei replied.

Seeing that the toner was almost scraped, Fang Buwei threw away the pencil, sat on the chair, and blew gently on the page of paper.

The toner slipped across the paper, leaving a little in the marks.

With Gao Sizhong and Zhao Shirui's eyesight, they could only see that the traces on the paper were some numbers, but most of them were blurred, and Fang Buwei could see most of the text clearly.

"What is the number of the phone number that nurse's boyfriend received before leaving Huangpu Road?"

Fang Buwei stared at the last set of numbers in the traces and asked Zhao Shirui.

On half of the paper, the rest of the content is just numbers, and there is only the four numbers in front of them, and there is an English letter "t".

Fang Buwei doubted that this is the abbreviation of "telephone" in English, meaning phone number.

Zhao Shirui quickly took out a notebook, opened it and said, "2527!"

The four numbers after the letter t are also 2527.

When it comes to match, these marks are left by Zhao Yulin.

It must have been Zhao Yulin who left a secret code in the middle of the note book while the checkout was settled. After Zhao Yulin left, someone came to tear away the paper with the secret code, translated the contents, and called Zhao Yulin's subordinates.

"After that guest left, how many people had touched this note book?" Fang Buwei asked the checkout officer.

"Only Accountant Xu of the Ministry of Education uses it to calculate the account!" The checkout officer replied, "I don't know if the other guests have moved. Moreover, after Accountant Xu settled the account, there were no customers in the middle. I went to the bathroom to smoke a cigarette..."

Fang Buwei turned his head and looked at Gao Sizhong.

Gao Sizhong replied in disappointment: "I was in a hurry to send someone to chase you, but where did anyone care about this book?"

"Section Chief, am I blaming you?" Fang Buwei hugged Gao Sizhong's neck and said with a smile, "Even if I were to be so tight... I didn't notice it if I didn't see Zhao Yulin leaving a password on it?"

"Please be relieved!" Gao Sizhong glared at Fang Buwei, "If you are wrong, you are wrong, and I dare not recognize it?"

"I know..." Fang Buwei responded with a laugh, and then said to Gao Sizhong, "I guess it was during the time when the checkout clerk left, someone took the opportunity to tear away the password..."
Chapter completed!
