Feng Jiashan also found out that Huang Sheng has a lot of hats, which are basically changed every day, but only this silk top hat has an inner lining.

More than that, the old mother even remembered the approximate time when Huang Sheng wore this hat to go out recently.

Fang Buwei checked it, and sure enough, it matched the date when Huang Sheng went to the café.

Fang Buwei also instructed Feng Jiashan that he must explain to the few people of the Huang Mansion who were bought, and he could not show his feet.

All night, Fang Buwei didn't sleep much.

He was speculating, what did Huang Sheng send today?

When is the next splicing?

As a result, early the next morning, Feng Jiashan came to report.

The old mother sent a message that when she went out in the morning, Huang Sheng went out wearing a hat with a tweed lining.

Huang Sheng is going to the café again?

Here's your chance!

Fang Buwei sneered.

Whether Huang Sheng used this hat to convey information or not, you will know at a try.

Fang Buwei immediately called Feng Jiashan and made detailed arrangements.

He arranged four groups of men to deal with various situations.

At half past twelve o'clock in the afternoon, Huang Sheng appeared in the café again.

It seems that Huang Sheng's move of using a hat to convey information is conclusive.

Fang Buwei estimated, yesterday's Huang Sheng received the order, and today he is here to hand over the task.

He and Feng Jiashan almost stuck behind Huang Sheng into the café.

Today is Monday, there are fewer guests, and there is no problem of no place to hang clothes and hats.

Huang Sheng handed the suit and hat to the waiter, and casually found a table and sat down.

Fang Buwei glanced at it, obviously feeling that Huang Sheng was a little nervous today.

Could it be that the information handed over today is not ordinary?

Fang didn't have time to think about it.

Taking advantage of Feng Jiashan's time to block the sight of the waiter and Huang Sheng, he quickly took out an identical hat from his bag and adjusted Huang Sheng's hat.

When the waiter hung up Feng Jiashan's clothes and came to greet Fang Buwei again, Fang Buwei had already put Huang Sheng's hat in his bag.

Fang Buwei waved his hand, refused the waiter's action of picking up the suit, covered his stomach with one hand, pretended to be in pain and asked, "Where is the bathroom?" ”

"Over there!" The waiter stretched out his hand.

"Good!" Fang Buwei ran over quickly.

It's all single-player grids, and there's no problem with concealment.

Fang Buwei closed the door, quickly put on his gloves, and then opened the bag and took out Huang Sheng's hat.

At this time, fingerprint recognition technology is already very mature, including the secret service is widely used.

Fang Buwei was not sure what information was hidden in Huang Sheng's hat, so he was even more uncertain if he could arrest Huang Sheng today.

So it has to be just in case.

He took out his top hat and glanced at it first.

It is indeed exactly the same as the one he asked Feng Jiashan to imitate, with not only an inner lining but also a mezzanine.

I don't know what's in the mezzanine, it's bulging.

Fang Buwei took a look, and after making sure that there was no silk thread at the mouth of the mezzanine, he peeled off the interlayer with his fingers.

Not paper, but a small cylindrical copper tube, about the thickness of a thumb.

Film?

Damn!

Fang Buwei scolded secretly.

He thought it was paper, and even the camera was ready, only to find out that it was film.

Is it useful to shoot a film negative?

Even if you want to change the film, it's too late.

As soon as you look at the length of the copper tube, you will know that this is a regular film.

The camera he brought with him was a spy plane, and the film was less than half the size of this one.

I had to find another way.

Fang Buwei listened attentively, but there was no movement left and right, put the suit on his head, and opened the brass pipe.

Sure enough, it was film, and there was a small note.

Fang Buwei glanced at the note first, and there was a series of numbers on it.

Another code?

Fang was not angry and gritted his teeth.

What he hates most is that spies use cipher codes to transmit information.

In the past, when this situation was encountered, it was basically that the spy had been caught, or was about to be secretly arrested, and it could be deciphered by simply forcing the codebook and the operation method to be asked.

But this time is different, and people cannot be arrested until there is conclusive evidence.

And even if there is evidence, it is necessary to consider whether to catch it in situ or hang the big fish with a long line.

But Fang is not for where there is this time.

If this case is not completely solved, Gu Zhenlong will definitely not let him leave Nanjing.

Your sister's!

Fang Buwei firmly memorized the numbers on the slip of paper in his mind, looked at the size of the film again, and then stuffed both things back.

He put his hat in his bag, put on his suit again, and went out of the bathroom.

As soon as Huang Sheng's coffee was served, Feng Jiashan sat next to him.

Both were located closer to the door.

Seeing Fang Buwei, Feng Jiashan stood up and gestured as he walked towards the door, meaning that there was nothing abnormal.

The connector hasn't come yet!

Fang Buwei lowered his eyelids and walked towards the door.

"Hello sir, what's wrong?" The waiter guarding the cloak asked.

"Not much, get a cigarette!" Feng Jiashan replied, took off the suit from the coat rack, and took out a pack of cigarettes.

Taking advantage of this effort, Fang Buwei quickly changed his hat back.

The enemy is too cunning to carry out the second scheme.

Fang Buwei walked downstairs quickly, went out of the door, and quickly glanced left and right.

"Sir, are you going to take a car?" A rickshaw stopped in front of Fang Buwei very eye-catchingly.

Fang Buwei's eyelids jumped suddenly.

This is a code sign that there is an emergency.

He followed the rickshaw driver's eyes, looked back, and saw a woman in a cheongsam with a showy show of flowers, twisting her waist towards a man in her thirties.

The man also wore a white silk hat on his head, with a white peony on it, exactly the same as Huang Sheng's.

This woman is her own person, and the current move to meet the suspect is also arranged by Fang Bu a long time ago.

Before Fang Buwei did not have a closer step, if it was found that someone suspected of being in contact with Huang Sheng appeared, the team members in charge of the emergency must find a way to delay the time.

This man came so quickly.

A few seconds slower, and there's no way to remedy it.

In the line of reporting information, the most feared thing is coincidences and accidents, if you change to yourself, when you are about to get to the joint, if you encounter an accident, you will definitely wonder if something has happened.

"He Hui!" Fang Buwei shouted loudly and waved his hand.

The woman in the cheongsam paused and turned back unhurriedly.

Seeing that it was Fang Buwei, the woman smiled shallowly, ran over and grabbed Fang Buwei's arm: "Why did you come down......?"

"Something just happened!" Fang Buwei replied with a smile, took the woman's hand and got into the rickshaw.

The man wearing the same hat as Huang Sheng just glanced at it and entered the door of the café.
