It turned out that Lin Jiangbei had two fingers, which were directly cut on the carved line of the chessboard.

As an amateur Go fourth dan, Lin Jiangbei has been exposed to at least hundreds of chessboards since he was a child, and although the engraved lines of these chessboards may be thick and thin, deep and shallow, there is always a general range, so that the deviation is not too outrageous.

However, Wang Longfei's catalpa chessboard was different, and it didn't seem to be anything special when it was placed on the ground, but as soon as Lin Jiangbei's fingers touched it, he immediately felt it, and the carved lines cut by these two fingers were at least one and a half times wider than the carved lines of the normal chessboard he had touched.

This is not only because he is extremely familiar with the width of the scribed lines on a normal chessboard, but also because of the extreme sensitivity to macro differences that he has cultivated in the past few years of forensic work—when autopsies are performed to find the cause of death, sometimes the scalpel deviates by even half a millimeter, and the conclusions are very different.

Lin Jiangbei immediately put this half of the chessboard in his hand, turned on the flashlight, and watched carefully under the dual light of incandescent lamp and flashlight. As a result, he found that not only the two engraved lines that he had just picked with his fingers, but all the engraved lines on this half of the board were one and a half times wider than the engraved lines of a normal chessboard.

Lin Jiangbei immediately picked up the other half of the chessboard for inspection, and came to the same conclusion.

The Japanese style of doing things has always been rigid and rigorous, and the pursuit of standards has been extreme, and it is hard for Lin Jiangbei to believe that any normal Japanese chess equipment manufacturer or craftsman would produce a chessboard with so many carved lines wider than the normal chessboard.

Even if this solid wood chessboard is made in China, Lin Jiangbei believes that the Japanese nobles who are so particular about Wang Longfei even have incense will never tolerate themselves choosing such a flawed chessboard.

Therefore, there is definitely a name hidden in the engraved lines of this chessboard!

Ye Luping didn't know Go, so he couldn't see any mystery in the engraved lines on the chessboard. He watched Lin Jiangbei take a flashlight back and forth on the two chessboards, and then stretched his neck to watch, but he stretched his neck and his eyes were tired, and he couldn't see what Lin Jiangbei was looking for on the chessboard, so he couldn't help but ask: "Jiangbei, what is there on this chessboard?" You take a flashlight and shine it over. ”

"There's definitely something. It's just not visible to the naked eye! Lin Jiangbei said, "Let's rush back to the bureau immediately and take a magnifying glass from the evidence room to check it." ”

"Magnifying glass? Then you don't need to go to the evidence room, I have it in the car, and the chief uses it to see the map! ”

Ye Luping ran out, and soon ran back from the car carrying a black military leather satchel, and then took out a magnifying glass from it and handed it to Lin Jiangbei.

There was no magnification on the magnifying glass, Lin Jiangbei tried to compare it with his finger as a reference, and felt that it should be an eight-fold or ten-fold magnifying glass.

So he came to the incandescent lamp, handed the flashlight to Ye Luping, and asked him to help shine it, while he held the chessboard in one hand and put the magnifying glass above the engraved lines of the chessboard with the other, and then looked through the magnifying glass.

Then he was shocked to find that the brown engraved lines, which were quite uniform in color with the naked eye, were magnified by a magnifying glass, and a group of small dots appeared in the middle that were slightly darker than the surrounding color. If it were someone else, it would be very likely that he would not know what these dots represented, but Lin Jiangbei could see at a glance that this group of small dots with less than one and more than five small dots arranged in different positions was actually a braille character for the blind.

Hehe!

Lin Jiangbei suddenly sneered.

This Yusuke Hashimoto is really not ordinary cunning, and he would even think of hiding the codebook in the way of braille characters in the engraved lines of the chessboard. Then he could take the opportunity of playing chess to translate the telegram he received against the password in the engraved line, and then translate the information he was going to send into a telegram and hand it to Tong Xiaoli for sending.

It's just that no matter how cunning the fox is, he can't fight a good hunter. Yusuke Hashimoto couldn't believe it when he was dying, but in the end, he was superior in his skills and found out the codebook that he had so carefully disguised and hidden!

Hearing Lin Jiangbei's sneer, Ye Luping couldn't help but feel happy in his heart, and hurriedly asked, "Jiangbei, have you found the password?" ”

"Yes!" Lin Jiangbei nodded, turned sideways, and asked Ye Luping to look into the engraved line with a magnifying glass, "If you take a closer look, can you see that there are some small dots in the enlarged engraved line that are darker than the surrounding color?" ”

"yes, yes, there are a lot of dots." Ye Luping nodded while watching, "Are these little dots passwords?" ”

"Yes, these dots are braille characters for the blind." Lin Jiangbei said, "Wang Longfei's codebook was written with these braille characters. ”

"Huh? Jiangbei, you still know Braille? Isn't it possible for you to crack the password directly? Although Ye Luping said that he was no longer surprised by Lin Jiangbei's manipulation, he couldn't help but be surprised when he heard that Lin Jiangbei knew Braille. You must know that although braille was introduced to China decades ago, in this era, not to mention people with normal vision like Lin Jiangbei, even the vast majority of blind people have no opportunity to come into contact with braille.

"Hehe, the braille is different in every country in the world. I understand that it is our Chinese Braille. Lin Jiangbei said, "The braille in this chessboard should be Japanese braille." You have to find someone who understands Japanese Braille, or find a comparison table of braille characters with Japanese 50 syllables. ”

Speaking of this, Lin Jiangbei patted the chessboard and said, "Okay, let's not waste time, hurry up and send these two chessboards to Principal Zhou and the chief inspector." ”

******

In the director's office, Zhou Fengshan and Du Chenghu faced each other silently, their faces gloomy and almost dripping.

Not only have they received a telephone call from the headquarters of the Intelligence Department, saying that the search for the code book has been entrusted to Li Guanfeng to carry out. And he just received a call from Zheng Xianggu from the intelligence department Hangcheng Radio. On the phone, Zheng Xianggu proudly showed off to them, saying that with his assistance, Inspector Li successfully found more than a dozen Go books hidden in Wang Longfei's code book from Tong Xiaoli's residence, and had sent someone to the bookstore to get back the genuine version of these dozen Go books.

Zhou Fengshan was so angry that he dropped the phone on the spot, and he couldn't wait to run to the Hangzhou Radio Station with a gun on his shoulder, and he grabbed Zheng Xianggu and shot him!

Zheng Xianggu, a bastard, didn't talk about eating inside and out, and even called them and slapped them in the face, how could they bear it?

"Bureau!" Du Chenghu bit his lip for a while, and finally made up his mind, "Otherwise, I will go to Nanjing tomorrow to meet the seat, and let him transfer Zheng Xianggu, the bastard, no matter what, otherwise this stationmaster of Hangcheng Station, I, Du someone, would rather let Xian!" ”

"Chenghu, don't be impulsive yet. Let me think again and see if there is any other way! Zhou Fengshan waved his hand at Du Chenghu, "Hangcheng Station is the base camp of our Zhejiang police, if we can't even handle a small Zheng Xianggu, how will the seat think about us?" We can't just go and find a seat at every turn! ”

At this moment, there was a sound of footsteps outside, and a loud voice was heard shouting outside: "Report to the chief, subordinates and Jiangbei are back!" ”
