Lin Ziren nodded, turned his face to Shopkeeper Song and said, "Don't mention those unpleasant things." You have to think about the cause and effect of this incident and provide us with relevant details so that we can solve the case in time......"

As he spoke, he opened the seal of the wine jar and handed it to the shopkeeper Song.

Shopkeeper Song hurriedly took it, poured a large bowl, raised his head and poured the bowl of wine into his stomach. "Good wine, good wine!" he smacked his lips, dancing with joy.

Lin Ziren took out the fragrant roast goose in the paper bag and put it on the table: "Don't just drink, it's easy to get drunk on an empty stomach, there are snacks here." ”

Shopkeeper Song smiled, tore a goose leg, and munched on it when it was put in his mouth.

Seeing the two bowls of wine falling into his stomach, the shopkeeper Song's face flushed red: "Even if you are dead now, you are full of wine and food, and you don't feel that you have lost ......"

Tang Yu asked on the side: "Mr. Song, haven't you seen Song Qingyang since then?"

"Nope. ”

"Then why do you say that he set up a tent in the city to teach?"

Shopkeeper Song was stunned, shook his head, and said slowly: "Of course I listened to what others said......"

"Who?" Tang Yu asked.

"The yellow shopkeeper who opened a silk village in the city. Shopkeeper Song was confused by a series of questions, raised his head, and stared at Lin and Tang with a pair of reddened eyes.

Lin Ziren said: "Don't be nervous, think slowly. Does this shopkeeper know Song Qingyang, how long have they been together, and what have they said to each other?"

"Of course I know, this yellow shopkeeper has a hobby, that is, he likes to write poems in his spare time. I often went to my bookstore back then, so I met Song Qingyang a few times. ”

"Where did they meet?"

Shopkeeper Song snorted in his nose, and a sneer appeared on his face: "Song Qingyang, a rooster and dog thief, what good place can he go, it's nothing more than a casino and a brothel." ”

"Can you elaborate on that? ”

"There is a Jinxiang Hutong on Qinglu Street in the east of the city, which is mostly a third- or fourth-class Lehu family. Shopkeeper Song said slowly, "Once Shopkeeper Huang accompanied a customer to socialize and went to a brothel called 'Qunfangpu'. I happened to meet Song Qingyang there, and the shopkeeper Huang knew that he was my brother-in-law, so he stepped forward to say a few polite words and asked me about my recent situation......

Tang Yu asked, "What did Song Qingyang say?"

Shopkeeper Song shook his head with a wry smile: "Naturally, his words flickered and he was hesitant, and later he said that he was teaching in a family in the city, so he left in a hurry." ”

"Doesn't this Huang shopkeeper know about him tricking you into the bronze Fang Ding?" Lin Ziren asked carefully.

Shopkeeper Song's face turned purple and said, "I haven't told him yet, because every spring I have to suffer from cold legs for a while, and it is difficult to walk." It's been a long time since we've seen each other. ”

"Why did the shopkeeper Huang mention this to you later?"

"A few days ago, I sent him a Song version of the only book "Ten Family Lexicon", and I went to the door for half a day. He just told me about it......"

Tang Yu also asked when he heard this: "Then didn't you go to find that Song Qingyang?"

Shopkeeper Song snorted again, disappointed, and said, "Even if you find him, what can you do? He printed that copy of "Walking with the Tiger" and owed me forty taels of silver, and it has been almost ten years, and he has not paid me back?"

Tang Yu frowned, knowing that it would be useless to say anything more. The three of them chatted for a few more inconsequential words, and then said goodbye and went out. Shopkeeper Song was very enthusiastic, and he was grateful again and again, and kept sending the two out of Wuyi Alley.

The two were worried about the case, went out of the alley, did not stay, and left Laobei City all the way.

When I returned to the pavilion where I stayed, not only Lin Fanghe, but even Cheng Liangjia, the head catcher, was there. Greeted each other, the two sat down, because they had been running for a long time, their mouths were hungry and thirsty, Lin Ziren went to ask for a pot of mellow black tea, brought it back, and poured it with Tang Yu first: "Drink a cup of hot tea first, scald your stomach, and then go out to get two drawers of steamed buns to eat later?"

Cheng Liangjia looked at the two of them, smiling without saying a word.

Lin Fanghe put down the file in his hand, turned his head, and asked: "Cheng Zhutou, according to what you just said, the result of Ying Tianfu sending to the land of Youyan to visit Guo Shoujing and the descendants of Guo Shoujing's Guo family is not very ideal, right?"

Cheng Liangjia replied and replied: "Since the last time Li Yongzhong of the Ministry of Industry explained to us the strange graphics that appeared in the bell tower, Feng Letai Feng Zhutou took a few catchers, dressed up as civilians, and went to Guojia Village, Xingtai, Jizhou, to secretly visit the descendants of the Guo family......"

Lin Fanghe asked, "Didn't they find anyone?"

"Looking for it, I found it, all of them were old and weak, women and children. Although this family is smart, it is not prosperous, and since Guo Shoujing, it has been in a single line. Cheng Liangjia sighed and said, "And Guo Taixing, the eldest grandson of the Guo family and a smart and supernatural since childhood, is not ......at home."

"Why is this happening?"

Cheng Liangjia didn't answer immediately, pondered for a moment, but said: "According to the people of the Guo family, half a year ago, a few people wearing red tasseled hats and wearing green robes and officials arrived, claiming that the Ministry of Industry wanted to open mountains and build roads and bridges in one of the most dangerous places in Youzhou, and they needed the assistance of people who were proficient in Kanyu design, and then took Guo Taihang away. ”

Lin Fanghe frowned: "There is such a thing? So did Feng Zhutou and them go to the relevant departments to check this matter?"

"I asked roughly, and the answer was that there was no such construction in Youzhou, Jizhou and nearby territories. ”

"Could it be that a big living person will be lost out of thin air?"

Tang Yu listened, and suddenly felt his heart jump, he hesitated for a moment, plucked up the courage and said: "Two adults, I was also here when I went to the Ministry of Industry to meet Cui Shangshu and Master Li that time. I remember that when Li Yong talked about this matter, he repeatedly mentioned a copy of the "Book of Wuhou Qi", did you find this book in Guo's house?"

Cheng Liangjia said: "The Book of Wuhou Qi involves the production of many delicate instruments, such as chain crossbows, guide carts and wooden oxen and flowing horses, of course we should pay attention to them. This time I went to Guojia Village in Xingtai, in addition to looking for Guo Taihang, mainly to check the whereabouts of this book. ”

"Well, yes. Tang Yu was in a sincere mood.

Lin Ziren was negligent in understanding other cases at the time, so he couldn't interject. He stood up, filled a few teacups, and sat back in his chair.

Cheng Liangjia took two sips of tea, stroked his beard, and said, "I can't hide it, but this disappointed us." Because according to the Guo family, the descendants of the great scientist Guo Shoujing also cherished this book very much, burned the ointment of the sundial, and couldn't bear to let go of it, and he didn't let the "Wuhou Qi Book" leave his side for a while......"

The descendants of the Guo family, who were willing to delve into strange books, disappeared for no reason, and found nothing, and the strange calculation formula appeared in an abandoned bell tower on the outskirts of the capital. When Lin Fanghe heard this, he tightened his eyebrows, "Cheng Zhutou, don't you think this matter is a bit absurd and weird?"

"I'm also constantly thinking about whether Guo Taixing will be controlled by someone and under house arrest. And lost his personal freedom?" Cheng Liangjia also felt the seriousness of the situation.

"It's entirely possible. ”

"Those people who disguise themselves as officials are most likely the gangsters who kidnapped him?"

"This happened," Lin Fanghe asked thoughtfully, "Why didn't Feng Zhutou report to the local government, inform the case and ask them to assist in the investigation?"
