As the foreman of the military machine, although Cao Yuying went to the palace to "work" every day, except for the "screaming" (the grand court meeting) once or twice a year and the "King Qingmen's Office" two or three times a year, he could only meet the emperor at some sacrificial ceremonies. Seeing Enjun showing off his waist card, he directly thought it was the emperor summoning him, and he was both excited and nervous. After all, too many things happened in the court these days.

After getting on the carriage, I suddenly felt something was wrong. I opened the curtain and looked at it. I couldn't help but turn around and asked, "Brother Eun-jun, where are we going?"

"Sir Cao is a little restless, you will know after waiting for the place."

"But this is the way to Xuannan!"

"Sir, have you seen it?"

"Yuying walks this road every day, can she not see it?"

Eun-jun was happy, changing her clothes and laughing, "Since it's the way home, Lord Cao doesn't have to worry, just say it's time to send you a ride."

"Where are you going to take me? Eunjun, you are not sending the imperial edict for falsely!" Cao Yuying was anxious.

"Mr. Cao, this joke cannot be made randomly. Even if I am brave, I dare not pretend to pass the imperial edict." Eunjun put the replaced yellow jacket aside. Thinking about it, I took out two purses from the yellow jacket, and smiled proudly: "What's more, I, Eunjun, have been deeply favored by the emperor. The emperor just gave several purses this afternoon. Why should I fake the imperial edict?"

Cao Yuying looked down and found that it was indeed the kind of purse that the emperor often gave. He simply snorted coldly and didn't speak again. Seeing his unhappy look, Enjun suddenly had a plan and a smug smile on his face again.

Feng Xiaobao didn't know what was happening in the car, but only knew that since the second shopkeeper could take the Cao surnamed "Houyitang", it means that there were ways to deal with the Cao surnamed. Thinking of this, he walked faster and unknowingly drove the carriage to the door of the bookstore.

"Second shopkeeper, we're here!"

"So quickly," Eun-jun packed up the clothes he had changed and the purse he had given to him by the emperor, and smiled sideways, "Please, Lord Cao."

Cao Yuying just now lay down by the car window and saw clearly. Not only did he know about where he was, but he was also not unfamiliar with this area. He cursed me and wanted to see what you sold in the gourd, and immediately turned over and jumped out of the car.

"Mr. Cao, please come inside."

“Where to go?”

"Get in."

Cao Yuying looked up at the plaque: "This is a bookstore, is it possible..."

"The outside is not a place to talk, so you will know when you go in." Eun-jun didn't want to eat the wind and sand outside, so she lifted up a door curtain made of a gray cotton mattress and drilled in.

Cao Yuying thought that since she was here, she would go in and take a look, so she bent over and followed in.

A very ordinary and deserted bookstore, with books piled up on the shelves and tables made of old tables in the middle, all of which were the most common Four Books and Five Classics, and I couldn't see the rare and lonely books. The shopkeeper was lying in the corner and dozing. Hearing the movement, he looked up and found that Eun-jun was lying down and then dozing off.

Cao Yuying was full of suspicion and was about to hold Eun-jun to ask what was going on. Eun-jun suddenly opened the inconspicuous small door beside the bookshelf. Cao Yuying reacted and hurriedly walked around the case and walked in.

I didn't know if I didn't come in. As soon as I came in, a big, thick guard wearing a yellow jacket actually walked out of a small house that looked like a duty room.

"Second shopkeeper, you are back!" Datou said in response.

"I'm back, where is the Fourth Master?"

"The Fourth Master is coming soon. The Fourth Master asks you to accompany the guests to Master Qingxian's place first."

"I understand," Eun-jun stuffed the changed clothes into Datou's hand, then turned sideways and said, "Please, Lord Cao."

Cao Yuying was shocked and couldn't help asking: "Brother Eun-jun, what this brother said just now has been dismissed from the Tongzheng Department of the Communist Party of China?"

“That’s right.”

"Aren't he being banned in the clan's mansion?"

"Yes, right? I can't explain it clearly in the next half time. If you don't see him, please ask him after you see him."

As soon as Eun-jun finished speaking, Qingxian walked out of a room and bowed from a distance, "The offender Qingxian welcomed Lord Cao."

Cao Yuying was stunned for a while before asking in surprise: "Brother Qingxian, how could you be here?"

"I will go wherever the emperor told me to go." Qingxian didn't want to explain too much, so he welcomed him into the main hall, greeted him to sit down, pointed to the stack of official documents on the coffee table and said, "Mr. Cao, please take a look at these first, and the criminal will tell you in detail after reading it."

"Please use tea by Lord Cao." Ji Lu brewed a cup of tea and retreated aside with a smile.

Thinking that Eun-jun was a Ganqing Sect guard who was fake, in addition to Eun-jun, there was a guard on duty in this secret courtyard. Thinking that Qingxian, who should have been banned in the jail of the sect, appeared here, and looking at the dazzling Western artifacts in the house, Cao Yuying realized that Eun-jun was not a fake imperial edict, and this bookstore would never look as simple as it looks from the outside.

He calmed down and decided to be at ease since he came, and first check out what official documents it was.

I don't know if I don't look at it, and I was shocked when I saw it.

It was all about the British, Mi, Buddha, and Russian, and the British, and Buddha had started a war with the Russians in Obaro, and fought from Obaro to Heilongjiang. This was definitely good news for the court, at least there was no need to worry about the aggression of Bao Ling and other barbarians who were reluctant to leave in Dagukou.

Just as he was watching, Qingxian, who was standing aside, said expressionlessly: "Mr. Cao. If you have anything you can't understand, you can ask."

"Can these news be true?"

"It's true!"

"Who inquired about this news?"

"This is a long story," Qingxian opened the door and pointed to the rooms on both sides and said, "This bookstore is called 'Houyitang', but it does not sell books, but is dedicated to inquire about the feelings of the barbarians. Hong Kong, Xin'an, Guangzhou, Macau, Xiangshan, Xiamen, Fuzhou, Ningbo and Shanghai have people in the places of "Houyitang". There are officials, Ying, Mi, Buddha, Russia and other rooms, specializing in summarizing, translating, sorting and verifying the feelings reported by various places in order to be consulted by the ministers and consultants of the Military Affairs Office."

Cao Yuying couldn't believe that the court had such a yamen, and was stunned for a moment.

At this time, footsteps came from outside.

Immediately afterwards, a familiar face appeared in front of me.

"Mr. Cao is here, Xiufeng is in a misfortune and welcomes you. Please forgive me."

"Han Xiufeng!"

"It's Xiufeng."

"How could you be here?" Cao Yuying stood up subconsciously.

"Mr. Cao asked, Xiufeng is the shopkeeper here. The people who inquire about the situation in Hong Kong, Xin'an, Guangzhou, Macau, Xiangshan, Xiamen, Fuzhou, Ningbo and Shanghai were sent out by Xiufeng. The people who summarized, translated, sorted and verified the situation in the rooms of England, Mi, Buddha, Russia, etc. were recruited by Xiufeng. Where would Xiufeng go here if he was not here?"

"The emperor ordered you to be dedicated to inquire about the affairs of the barbarians?" Cao Yuying was skeptical.

"This is still fake," Han Xiufeng smiled slightly.

Cao Yuying thought about it and asked again: "Why do you want to be so sneaky when you are doing it for the court?"

"When you say it carefully, Xiufeng feels wronged," Han Xiufeng walked up to him, leaned over and picked up a document, pointed to the date above and said, "Let's talk about this date. The Western Bible used the Western Bible calendar. I thought that the day they believed in the birth of Jesus who was sanctified in flesh began to count the year, and we used our calendar. If we don't study the Western Bible calendar carefully, then my brothers in the "Houyi Hall" will be useless even if they fight for the 100,000-year-old traitor, because they can't figure out which year or month it happened."

"But what does this have to do with you being so sneaky?"

"Yes, it's a big deal!"

"But I heard it very well."

"Mr. Cao, you forgot what the Imperial Heavenly Prison does? If the men of the Imperial Heavenly Prison who are proficient in astronomy and geography know that I am studying the Western Yi calendar here, they will not have to come and smash my "Houyi Hall"! I am afraid of death, and I dare not be almost slapped by Lingchi like Tang Ruowang during the Kangxi Dynasty."

Cao Yuying reacted and didn't know what to say, Han Xiufeng took out a strange Western artifact from the shelf and said meaningfully: "What's more, this place is not only studying the Western Italian calendar, but also studying the astronomy and geography of the Western Italians. For example, this thing called the Quadrant was made by the Western Italians hundreds of years ago. It is said to be specially used to measure how high the day is, and then use it to sail on the endless ocean."

Qingxian suddenly interrupted: "The emperor is the emperor, is the energy of heaven?"

Han Xiufeng put down the quadrant instrument, picked up another strange object, and then said: "This circled object is called...it is..."

Ji Lu just registered and said at the right time: "Report to Mr. Han, this is called the Heaven Testing Technique."

"Yes, yes, yes, it is called a celestial meter. It is said that this was made by the Western Yi through the "cross-measurement method" learned from the great cannibal hundreds of years ago. It is also a celestial meter, and the celestial clock, all used for celestial meter. If the adults who watched the celestial phenomena at night in the Imperial Heavenly Prison knew that I would not have been taken to the Caishikou to Lingchi?"

Cao Yuying reacted and couldn't help but smile and said, "So you are worried about the Imperial Heaven."

"It's not just about the Imperial Heavenly Prison, but also about the Ministry of Rites, the Lifan Academy, the Imperial Hospital and even the Imperial College."

"What are the Ministry of Rites worried about?"

"Mr. Cao, do you really don't know or fake? Dealing with Western Yi was originally a matter of the Ministry of Rites. Inquiring about the movements of Russian Yi should be the Lifan Academy. If they knew that Han Xiufeng, I, had robbed their errands, wouldn't they have eaten me alive?"

"Where is the Imperial Hospital?"

"The same is true for the Imperial Hospital. Not to mention anything else, it just happened a month ago. A fellow villager, a daughter, who was born with a three-petal mouth. Even if she hired an imperial physician, the Imperial Doctor would be helpless. But the Western Yi doctor could cure it. I just sent Shanghai to treat it not long ago. I don't believe in foreign religions and don't like Western Yi, but I think we should learn how to treat the three-petal mouth of Western Yi. We have to translate the Western Yi medical books and study it carefully."

Cao Yuying finally realized why Houyi Hall was so secretive, and couldn't help but laugh: "If the Hanlin Academy and the Imperial College knew that you didn't read the books of sages and hid here to study the evil ways of the Western barbarians, you would still be ruined."

"I'm obviously working for the emperor and serving the court, but I'm going to make it sneaky, as if I'm doing something shameful, so I feel wronged."

"Aren't you afraid that I will tell you?"

"Mr. Cao is really good at speaking. If you are so pedantic, can the emperor let you be the foreman of the military aircraft Zhangjing?"

"Han Xiufeng, stop being mysterious. What's wrong with the emperor's order of Enjun to bring me here?"

"To be honest, Xiufeng asked the emperor to ask Eun-jun to invite you."

"You invited me?"

“That’s right.”

"What do you want me to do?"

Han Xiufeng said bluntly: "Please report the Yixiang that I have sorted out in my 'Houyi Hall' to Prince Gong, Lord Peng, Lord Mu Yin and Lord Du."

Cao Yuying asked coldly: "Although you are a registered Zhangjing, you still have waist signs that go in and out of the palace ban, and you can also walk on the military Zhangjing. Why don't you report it?"

"Because Xiaguan is too busy," Han Xiufeng pointed to the room full of Western artifacts and said helplessly: "Xiaguan not only needs to inquire about the affairs of the foreigners, but also needs to stare at the people outside to translate the Westerners' mansions and books. He also wants to report to the emperor, Prince Yi, Prince Zheng, and Wenzhongtang. It's really a waste of time."

Not only did Cao Yuying not hate this job, but he was willing to be this soundtrack. After all, this is a secret in the secret, and not everyone has the opportunity to participate. After thinking about it, he asked again: "Who other adults know about the matter here besides the emperor, Prince Yi, Prince Zheng and Wen Zhongtang?"

"Lord Sushun knows, Prince Gong and Lord Peng and others know that Bai Zhongtang originally knew something, but probably won't know it in the future."

"When did Prince Gong and Lord Peng know?"

"Mr. Cao, are you asking about 'Houyi Hall' or the emperor ordered me to be dedicated to inquire about the affairs of the barbarians."

"The Emperor ordered you to be dedicated to inquire about the affairs of the barbarians."
