After a few minutes of pause, the young man in the cap walked in and sat down again, ordered a few beers, and took out a book from the bookshelf next to him to read it. However, he didn't seem to be very interested in the contents of the book, so he pushed it aside after looking at it twice, picked up his phone and swiped it, and looked up in the direction of the back room of the bar from time to time. In this math bar, most people read and write there, and the behavior of the cap swiping the mobile phone is a bit abrupt.

After a while, a few more people entered the bar, dressed in refined clothes, looked at the caps, nodded slightly, asked for a few glasses of wine, occupied two tables, and began to talk in a whisper. In a quiet bar, this little buzz seems so harsh.

Bai Qianbei drank a few glasses of wine, felt a little stooly, asked the direction of the bathroom, got up and left the bar.

As soon as Bai Qianbei entered the bathroom, the bar owner accompanied Qi Bin out, smiling all over his face, muttering something at the same time, taking out a small paper bag from his pocket and stuffing it into Qi Binxuan's hand. Qi Binxuan casually put it into the inner pocket of his clothes.

At this time, the capable young men who came in from behind the two tables next to him stopped Qi Binxuan's way and said, "Qi Binxuan, please come with us." ”

Qi Binxuan frowned and asked, "Who are you, why should I go with you?"

"We're from the Eagle Metropolitan Division, and we suspect you of espionage, so you'd better come with us honestly. Otherwise, don't blame us for being polite. The leader took out a token, let Qi Bin Xuan look at it, and then put it away.

Qi Binxuan was slightly surprised, the Eagle Capital Division is a professional spy agency of the Hungarian Zhen Kingdom, in charge of the ban on entry and exit of the Khan's palace, and at the same time, it circulates among the people, secretly serves and observes, and is a spy organization directly under the Khan. Qi Binxuan initially suspected that these were the political enemies of the Eighth Prince, that is, the radicals, but he didn't expect that they were organizations directly affiliated with the Khan.

Qi Binxuan said: "Yes, but I need to inform the Eighth Prince." ”

"It's not up to you. Several people pushed and shoved Qi Binxuan out, and at the same time, several people were separated, and the bar owner and bartender were also taken away.

Bai Qianbei, who came out of the bathroom, saw the chaos here, and did not rush forward, but listened to the conversation of several people from a distance, and after hearing the name of Takatsuji, he hurriedly slipped out of the back door of the bar.

Bai Qian doubled out of the bar, hurriedly stopped a taxi, said to go to the Eight Kings' Mansion, and began to call Battle.

When Battle learned that Qi Binxuan was captured by the Eagle Capital Division as a spy, he was also extremely surprised, and hurriedly reported it to the Eighth Prince.

After hearing this, the eighth prince was also surprised, this Eagle Capital Division was not a place he could influence. Interfering with the Eagle Dusi in his capacity would attract the Khan's suspicions. However, Qi Binxuan couldn't help it, and after discussing with Batel and other staff, he decided to meet the Khan directly to protect Qi Binxuan.

The eighth prince hurriedly entered the palace and met Khan Dulif. In the study, the Eighth Prince saw Fuqu Dabxing reporting to the Khan.

After Du Lifu saw the eighth prince, he asked with a smile: "The eighth king is not recuperating at home, why are you in such a hurry to see your brother?"

The eighth prince bowed his hand slightly and said, "Khan, I recently recruited a new staff member, who is resourceful. I worship him as a military advisor and as my chief staff. However, when he went out for a stroll today, he was captured as a spy by the Eagle Capital Division. The younger brother was anxious, and came to ask the Khan, what was going on, but it was clear to check. If the evidence is conclusive, the younger brother will not tolerate it, and if it is just suspicion, I hope that it will not be bent into a trick. ”

The Khan was also slightly surprised when he heard this, and said that the Eagle Capital Division had the duty of supervising hundreds of officials, but the sensitive matter of arresting the prince's staff still needed to ask the emperor for instructions, even if the matter was urgent, at least it needed to be reported afterwards. However, the eighth prince has already learned the news, and he has entered the palace to ask himself, why haven't he even gotten a rumor?

Da Buxing said beside him: "Eighth Prince, it is the duty of the Eagle Capital Division to serve the people. If there is suspicion of your staff, arraignment is due process. The one who is clear is self-purifying, if he has no problem, he will be put back, why should the eighth prince stand up for him. ”

The Khan waved his hand, signaling Dabxing not to say more, and then said to his attendants: "Chuan Ying Du Si Zhi Ang Qinfu is here. ”

After a while, it was known that Aung Qinfu hurriedly entered the palace. The Khan questioned Aung Qinfu about the arrest of the Eighth Prince's staff. Ang Qinfu was also puzzled, and said: "My subordinates don't know about this matter yet, so I'll ask my subordinates first." ”

As he spoke, Aung Qinfu took out the communicator and contacted his subordinates through the encrypted channel, and learned that a soldier was in charge of the arrest.

The Khan ordered Aung Chin Fu to bring Brenfu and the Eighth Prince's staff and others to be tried in court.

After a long time, Bu Renfu entered the palace with two of his subordinates, Qi Binxuan, the bar owner, and the bar bartender.

In the Khan's side hall, Aung Chin Fu interrogated the case in place of the Khan.

"Burenfu, why did you arrest this Eighth Prince's staff?" asked Ang Qinfu straight to the point.

"Back to Khan, my lords. The minister got a tip-off that this staff member of the Eighth Prince may be a spy inserted into our country by Song Guo. So, we monitored him. In the bar, he and the bar staff were seen behaving suspiciously, suspiciously confirming his identity as a spy, and he was arrested. ”

"Oh, how suspicious are they?" asked Aung Chinfu.

As soon as he entered, the staff member exchanged a secret message with the bartender, after which the bartender led the staff into the back room of the bar to talk to the boss in secret, and it was a long time before he came out. One of Burenfu's subordinates was the cap who followed Qi Binxuan and the others into the bar at that time.

Ang Qinfu asked Qi Binxuan: "Qi Binxuan, do you have any arguments against this?"

Qi Binxuan said: "Hui Khan, all the adults, the villain is just invited by the Eighth Prince, and the ordinary people who come to serve are by no means spies. As for the staff member saying that I had a secret letter with the bartender, where did that start?"

The cap said, "I knew you wouldn't admit it, so I recorded it." As he spoke, the cap took out his phone and released the audio at that time.

"Odd and even don't change. ”

"Symbols look at quadrants. ”

"Fake sword, square sword. ”

"Earthwork, Fang spit out two chickens. ”

These strange sentences came out of the audio, and even the Eighth Prince was a little skeptical that he had hired a spy.

Seeing that the evidence was conclusive, Ang Qinfu also breathed a long sigh of relief, if it was really a mistake by his subordinates, he would not look good. He asked, "Qi Binxuan, what else do you have to say now?" ”

Qi Binxuan said: "My lord Mingjian, this is not a code at all. ”

"Then what are these strange words? Are you bullying the officials for ignorance?" Ang Qinfu was also a little angry, this is talking nonsense with his eyes open, if it weren't for the Khan's palace, he would have to torture the people in front of him.

At this time, the bartender next to him said, "My lord, this is indeed not a code. The younger one is a native of Hungary and is now studying at university and working in a math bar in his spare time. Small identities can be strictly checked by adults. These languages are mathematical formulas. As for why these formulas are spoken, it comes from an unwritten bar rule that if you can teach the bartender a math, you can have a free drink. This is something that our repeat bar customers know. Many repeat customers invite their friends to come here and brag about being able to drink a free glass of wine. ”

"Math bar?", "math mantra?", "unwritten rules?", these nouns make everyone confused.

So the bartender explained the specific meaning of the four sentences and the corresponding knowledge points to the adults word by word. He is worthy of being a college student, and his speech is the truth.

At this time, the cap kneeling next to him was already in a cold sweat, if this was really not a code, then his sin would be great. If it was okay to say that in the Eagle Capital Division, it would be enough to just let the staff go, but it turned out to be a trouble for the Khan, and it was not a matter of simple words.

Thinking of something, the cap grabbed at the life-saving straw and asked, "Then what do you mean when you say, 'It's you,' 'Our boss has been waiting for you for a long time, please inside?' If it's not a spy, how can you have such inexplicable words." ”

The bartender smiled bitterly: "This lord, this is because the two formulas of 'fake sword, square sword' and 'earthwork, square spit out two chickens' are Qi Binxuan's original." This is already known to many people in the International Civilian Mathematics Forum, and you can check it on the forum if you don't believe it. Because of these two formulas, the boss has been friends with Qi Bin for a long time, and he has long invited him to come to Hun Zhen to play. My boss has told me about this many times, but because it's been half a year, I can't remember it clearly. I met the main owner this time, do you think I can not be excited, say that the boss has been waiting for you for a long time, and ask him to find the boss, isn't this normal, what's inexplicable?"

Ang Qinfu next to him felt that his face was a little feverish, and he just said that he was bullying his own officials and was ignorant, which was really a slap in the face, bullying himself and his subordinates into ignorance.

Obaban Renfu said abruptly: "It's just your words, Qi Binxuan spent nearly two hours with the bar owner in the back room of the bar, who knows what he did." It is very likely that it was the exchange of secret information. ”

That's a bit of a rhetoric. At this time, the bar owner said, "My lord, we were in the back room, and we just talked about some math learning and understanding, and at the same time did a set of test papers together." ”

"Do the test papers?" This time, everyone fell into a circle of confusion again, and friends who had been friends for a long time met to do test papers together, what kind of strange behavior is this.

"Ridiculous, do you think you're mentally retarded?" Brenfu yelled angrily.

"It's really a test paper. If you think about it, you will understand that when two drinking friends meet, they must fight for wine, two martial artists meet and try their martial arts, and two literati meet and fight for their talents. Then what should we do when two high-IQ talents who love mathematics meet, of course, it is a competition of IQ. How to compete for IQ, of course, is to use quantifiable papers. Those two papers are still in my office. You can go and get it and check it, check your notes. The bar owner said.

The khan watched the drama in the palace and waved his hand at Aung Qinfu.

Aung Qinfu understood and ordered his subordinates to take the test papers and bring them to the professionals of the appraisal department.

In this side hall, the personnel of the forensic department analyzed the time of the handwriting on the examination paper and determined that it was the same day. Check the handwriting to make sure it is the handwriting of the boss and Qi Binxuan.

In the face of the appraisal results of the appraisal department, Burenfu still resisted stubbornly: "This paper is only a few hundred words, and it can be written in half an hour. You've been there for almost two hours, and you must have done something else. ”

Qi Binxuan looked at Burenfu with an idiotic gaze and said: "This is a test paper issued by the International High IQ Association, and the degree of difficulty is recognized. If you think you can make it in half an hour, you want you to give it a try. ”

Burenfu picked up a paper angrily, but when he saw the first question, he was blindsided, and he recognized every word of the question, but when he put it together, he didn't understand what it meant at all. I looked at the bottom and didn't know if it was the bar owner or Qi Binxuan's answer, what was written on this step and this symbol?

Brenfu held the test paper, his hand trembled, and the hand holding the test paper became stronger and stronger. Finally, the thin paper could not resist the strength of Brenfu, and it was torn in half.

The cap seemed to think of something, and suddenly shouted: "I remember, when I came out, the boss stuffed this staff member with a paper bag, which was put in his coat pocket." We hadn't had time to take it out to check it out, it must still be in his clothes. ”
