Zhou Fengshan and Du Chenghu glanced at each other, the gloomy mood disappeared in an instant, the faces of the two people became calm and peaceful, and a high-ranking aura of everything under control spontaneously emerged.

Zhou Fengshan even picked up the teacup and took a sip of the obviously cold tea to moisten his throat, and then said unhurriedly: "Come in!" ”

The door was pushed open from the outside, and Lin Jiangbei and Ye Luping walked in side by side.

"Jiangbei, Li Guanfeng took the lead and searched the code book, right? I can't blame you for this matter, even I didn't expect that Zheng Xianggu, the king of eight lambs, would eat inside and out, and come to such a hand. Zhou Fengshan stood up, with a warm smile on his face like spring, and while greeting Lin Jiangbei, he comforted him and said, "But what if Li Guanfeng snatches the codebook?" This spy team was cracked by our Hangzhou Station! Wang Longfei was captured by you Lin Jiangbei! If it weren't for the success of our previous actions, Li Guanfeng would be an immortal, and I'm afraid I wouldn't be able to find the codebook, right? So you don't have to worry about this matter, although the codebook was searched by Li Guanfeng, at least half of the credit for finding the codebook is to be recorded on you! ”

Lin Jiangbei saw that he hadn't spoken yet, so Zhou Fengshan gushed such a big call to comfort himself, and couldn't help crying and laughing.

"That, what, Principal Zhou," Lin Jiangbei scratched his head and said to Zhou Fengshan, "Wang Longfei's codebook was not searched by Inspector Li, but was found by the students and Brother Ye and brought back to you." ”

"What? What did you say? Zhou Fengshan was stunned for a moment, a little suspicious that he had heard it wrong. Because he clearly heard Zheng Xianggu showing off on the phone, saying that the dozen or so Go books with hidden codebooks were all pulled by Li Guanfeng to Hangzhou Radio, how could they be found by Lin Jiangbei and them?

Could it be that Li Guanfeng didn't finish the Go book when he took it, and left one behind?

It's unlikely, right?

"The student said that Wang Feilong's codebook was not searched by Inspector Li, but hidden in these two halves of the chessboard, and was brought back by the student and Brother Ye." Lin Jiangbei raised his voice, and while reporting loudly, he and Ye Luping took out the half of the chessboard sandwiched under his arm and handed it to Zhou Fengshan.

Zhou Fengshan could finally be sure that he had heard it correctly this time, Lin Jiangbei and Ye Luping had really found the codebook and brought it back. He snatched the half of the chessboard from Lin Jiangbei's hand, and couldn't wait to look at it in his hand.

At the same time, Du Chenghu, who was standing behind Zhou Fengshan, also rushed up with an arrow, snatched half of the chessboard in Ye Luping's hand, and looked through it in his hand.

The two of them looked through it and muttered in their mouths: "What about the mezzanine?" Where is the mezzanine where the codebook is hidden? Why can't you find it? ”

"Report sir!" Ye Luping looked at Zhou Fengshan's anxious appearance, and couldn't help but remind him loudly: "The chessboard has no mezzanine, and the codebook is not hidden in the mezzanine, but hidden in the engraved lines on the chessboard. ”

"In the engraved lines on the chessboard?" Zhou Fengshan and Du Chenghu both raised their heads in surprise and looked at Ye Luping. The engraved lines on the chessboard are only a little bit wide, how can the codebook be hidden?

"Yes!" Ye Luping nodded and said, "It's hidden in the engraved line, but you have to use a magnifying glass to observe carefully to find it!" ”

Zhou Fengshan and Du Chenghu both blushed, understanding that they had both made the mistake of empiricism.

"Stinky boy!" Zhou Fengshan slapped Ye Luping's head in annoyance, "Since you know, why didn't you remind you earlier?" It hurt me to work with Cheng Hubai for a long time! ”

Obviously, your old man is too impatient, and he doesn't wait for Jiangbei and me to report well, right?

Ye Luping covered his head, muttering in his heart, and he didn't dare to make the slightest excuse.

Lin Jiangbei looked at Ye Luping's resentful appearance and forced a smile, and told Zhou Fengshan and Du Chenghu the details of how they found the code book. Then he handed the magnifying glass to Zhou Fengshan and asked him and Du Chenghu to watch the braille in the engraved lines on the chessboard.

So Zhou Fengshan and Du Chenghu hugged the chessboard, returned to the desk, turned on the floor lamp on the side, and carefully observed the engraved line with a magnifying glass.

Isn't that an observation? With the naked eye, there are no special engraved lines under the magnifying glass, and there are groups of small dots.

"It's true! This Wang Longfei is really very cunning, and he will hide the code book in the engraved lines of the chessboard! Zhou Fengshan handed the magnifying glass to Du Chenghu, and laughed at Lin Jiangbei, "Jiangbei, Jiangbei, you have found out like this, even if Wang Longfei is under Jiuquan, I'm afraid he won't be blind, right?" ”

"Bureau, what Wang Longfei is? That little Japan's real name is obviously Yusuke Hashimoto! Du Chenghu also laughed and said to Lin Jiangbei: "Jiangbei, are these little dots Braille?" How do you understand? ”

"Report to the Inspector General that the students took in two L.A. orphans outside, one of whom was blind. So I found some Braille textbooks and taught him to learn them in my spare time. Lin Jiangbei replied.

"I see! That's why good people have good rewards! Du Chenghu nodded and said to Zhou Fengshan: "If you are a person who has never been exposed to Braille, when you see these small dots, you may ignore the past under carelessness." ”

"Not necessarily!" Zhou Fengshan shook his head, "Others may ignore it, but if you change it to Jiangbei, even if you haven't been exposed to Braille, you won't ignore it." ”

Speaking of this, Zhou Fengshan looked at Lin Jiangbei again, "Jiangbei, although Chenghu and I know Braille, we don't know much about what this braille is. Now you explain this knowledge to us, so that when we report to Mr. Duan, if he asks about this matter, we can always answer one or two. ”

Du Chenghu nodded, he also meant the same. Otherwise, they went to report to Duan Yinong, and if Duan Yinong asked, what was the matter with this braille, but they didn't know what was going on, it would have been a hundred points of merit, maybe it would have been reduced to fifty points in an instant.

Lin Jiangbei's request to Zhou Fengshan was not surprising, originally an excellent subordinate, when reporting to the superior, should do enough homework and master all aspects of the matter for the superior to consult. Zhou Fengshan was able to sit in his current position, and he naturally understood the key in the middle.

So Lin Jiangbei explained to Zhou Fengshan.

"Braille, also known as Braille, is a phonetic script invented by the blind French man Braille for the blind. It is composed of 64 characters formed by a total of 64 combinations and changes between the six convex and concave dots in three rows and two columns. Some of these characters represent initials, some characters represent finals, a initial character and a vowel character put together, it constitutes the pronunciation of a word, if the language has a tone change, but also after these two characters add a third character, indicating the tone change. ”

"Because the pronunciation of the language is different in every country, the braille is different in every country. Take our country as an example, there are currently three braille systems, namely Kangxi Braille, Fuzhou Braille and Xinmu Keming Braille. ”

"Among them, what is popular in most parts of China, including our Zhejiang Province, is the braille character designed on the basis of Nanjing official dialect. It uses Nanjing accent as the standard tone, with 18 blind character initials, 36 blind character finals, and one blind character tonal. ”

"And the pronunciation of Japanese is composed of fifty Japanese kana equivalent to pinyin, so the Japanese blind characters should correspond to the kana of the fifty syllables, so as long as you can find this list of braille characters corresponding to the fifty syllable kana, and then give it to someone who is proficient in Japanese for translation, you can decipher this codebook!"

"Proficient in Japanese?" Du Chenghu slapped the table when he heard this, and said to Lin Jiangbei and Zhou Fengshan, "Yamada Yitaka said that Jiangbei's Kansai dialect is more authentic than that of him, an authentic Kyoto person, why don't we take Jiangbei to meet Mr. Duan?" ”
