"Dongzan came to see his son-in-law for personal friendship, not for public servants." Lu Dongzan touched his long and neatly trimmed beards and smiled at me happily, not as depressed as he was when he handed over the letter of state to apologize yesterday.

"Oh, I'm not for public service?" I repeated Lu Dongzan's words, looking at the Tubo with a cheerful and energetic look, and was very curious. Could it be that he is really a person with open mind?

"My husband and wife don't believe it. Although Dongzan has a lot of controversy with the husband and wife in official business, Dongzan privately admires the style of the husband and wife, and he also listens to others. The husband and wife are the heroes of the world. Dongzan has long been determined to make friends with the husband and wife. Yesterday, the business was over. Dongzan hopes to have the honor of having a drink with the husband and wife. I hope you can give me some gifts to the husband and wife in the evening. Today, at the hour of You, Dongzan is waiting for the husband and wife in Wangjiang Tower on the banks of the Qujiang River..." Lu Dongzan flattered me while inviting me to eat and drink. This kind of thing, well, the prince brother also wants me to go to my Lu Dongzan to ask two Tubo girls to see the new things. Since Lu Dongzan came to the door, he happened to mention this matter in the evening, which was also considered to have done something for the prince brother.

"Don't worry, Fang Jun will definitely visit on time." He stood up and bowed his hand to return the gift. Lu Dongzan was very happy when he heard this, and he was happy and said he was very happy. He sent this Tubo grandson out of the door, and kept whispering in my ears about how delicious the food on the Wangjiang Tower by the Qujiang River was, and the wine was even more mellow. Before he could finish it, he came to my ear and whispered in a very obscene way: "Mr. I don't know, there are several amazing people in the Wangjiang Tower, hehe..."

"Hehehe..." A stunning man? Well, he clasped his fists at the Tubo who was on the horse and said: "Don't worry, even if you overcome all obstacles, Fang Jun will definitely attend the banquet."

"Okay, it's up to you, go to Dongzan! Hahaha...you!" Looking at the old guy's agile back, well, this Lu Xiang is also a good character. Well, a gentleman keeps his trustworthy. Even if he is a knife, we have to go and meet this Lu Xiang Ye. Of course, it's not for the sake of looking at beautiful women. I can swear in the name of a gentleman.

Back to the courtyard, changed into the casual clothes he had just put on, and took care of his outfit. He was about to go to the courtyard, "Lu Dongzan came for personal friendship, just to invite you to the banquet?" The palace maid sister was too cautious, so I slammed the mouth and smiled at the palace maid sister, "Well, that's true."

"Young Master." The palace maid raised her pretty face, stared at me for a while, and called softly.

"Well, what's the matter?" Let Green Butterfly put the shovel on the top of my head for me, holding a bronze mirror to see if there is anything wrong with Yongguan on my face. "Young Master, don't blame Zhao'er for being too careful. Although Zhao'er has never seen this person, she has heard and seen the news. This Lu Xiang is not such a good person to meet. Today I invite the young master to have a night banquet. I hope you will be more careful..." The palace maid stood up with her feet. Her eyebrows were locked in dark clouds, and her lips were tightly pursed, as if she had encountered a difficult thing.

"What's wrong? Sister Zhao'er, is that old Tubo man trying to harm our young master?" Lu Die said anxiously, his little hand tightened, and almost pulled off my crown and his hair. I screamed in pain. I was so scared that the little girl trembled and then realized that she had done something wrong.

"Young Master, I'm sorry, Green Die was really careless..." Green Die apologized repeatedly.

"It's okay. Just be careful. I'll pull my young master into a bald head, be careful of family rules!" He said to Green Butterfly half-jokingly. This girl made her pink face turn red, and she finally felt less guilty between her eyebrows-

He pulled the hand of the palace maid's sister, smooth and grinned at the beautiful lady who seemed a little dull, and said with a gentle smile: "Don't worry, Zhao'er, I have never blamed you. You are dedicated to relieving my worries. If I blame you, how can you be worthy of your sincerity? That young man is such a fool."

"Young Master, I..." The palace maid sister gently opened her lips and wanted to speak, but she seemed to be stuck. A faint crystal clearness appeared in her beautiful eyes, the corners of her mouth were slightly raised, and the joyful joy climbed up to her eyebrows.

"Okay, Zhao'er, as the saying goes, everything is indifferent. I understand your thoughts, and you both understand your thoughts, hahaha, I will go!" I hugged you and kissed you, and went to work with a proud and proud manner.

When we arrived at the front yard, we ran into the housekeeper who was about to go out. After asking, we found out that our restaurant in Chang'an had quietly started construction. Well, another day, we would go to our restaurant to take a look and chat. As soon as we walked out of the gate of the house, an official rushed over. Why did Zhong Hua, a doctor in the Ministry of Works who had been in contact with me for sand table engineering?

Zhong Hua turned around and got off the horse when he got closer, bowed two steps forward with joy: "Zhong Hua, the doctor of the Ministry of Works, met Mr. Fang."

He quickly bowed his hand and replied: "It turns out it is Lord Zhong Hua. I don't know what is the important matter for you when you are in a hurry?" Looking at his appearance, is there any progress in the sand table?

"Five days ago, the last drawing master had also returned to Chang'an from Qizhou. A group of drawing masters from our Ministry of Works rushed to paint day and night. As of this morning, the entire drawing has been almost completed. Zhong Hua will come to report the good news to Mr. Fang for this matter, and ask the master to follow me to the Ministry of Works to see if there are any omissions."

"Oh?! The full picture has been completed?" I couldn't help but exclaim, with such high efficiency. As the head of map drawing and sand table civil engineering project, we naturally have to go and check it out.

"Sir, please go to the Ministry of Works first. By the way, Uncle Shen, send someone to the Jinzouyuan for me to say, "Young Master, I have something to go to the Ministry of Works. If you have something important, you can come to the Ministry of Works to find me." He stepped on the back of the horse and turned his head to speak to the housekeeper, and then followed the official of the Ministry of Works to hurriedly go.

There are many people working in the drawing room in the Ministry of Works, and everyone is coming and going in a hurry, looking very busy. Zhong Hua is currently leading the way and walked before a large volume: "Please look at it, this is the full picture of Guanzhong Road, just completed..." He was very proud, standing next to me, waiting for me to check.

"Look, um, very detailed..." He said praising words, stood beside Zhong Hua, looked for a long time, and pointed out his finger: "This is Chang'an, right?" Not bad, after I and many map masters, I already know how to use shadows to show the heights of the mountains. At least it will not be like the previous map, just like a mountain, like a child's thing.

"Young Master Gao Ming, this is Chang'an. Look, this is Bashui, this is..." Zhong Hua said a lot, and his fingers kept gesturing on the long scroll.

"Um..." As he nodded, he looked at the map carefully, and always felt that something was missing. At this time, a drawing master passed by me with a picture. "Please wait a moment, can you lend me the picture in your hand?" He stopped the drawing craftsman and was stunned. Zhong Hua didn't know why I was like this, but just asked the drawing master to hand me the drawings in his hand. When he was waiting at Zhong Hua's instructions to say something to me, I raised my hand to stop it. This was also a picture. I was holding the drawings and proofreading the drawings on the table. A flash of inspiration in my mind, and I was so excited that I didn't know what to do. I raised my arms and shouted: "Frontitude and latitude line! Benchu ​​Meridian line! Damn! That's that thing."

"Frontitude and latitude line? Benchu ​​Meridian line?" Zhong Hua and the drawing master beside him looked at me for no reason.

"It's this thing, do you know how many miles there is in a straight line from Chang'an to Weishui?" I was so excited that I almost didn't know how to organize the language. Yes, the meridian line and Jingwei line are divided with the Taiji Hall in Chang'an City as the center. Each hundred or two hundred miles is divided once. The first line is zero degrees, and the second line is one degree. According to this painting... it forms a complete geographical coordinate, not only in military but also in civil affairs.

"Taji Hall is the midpoint, and divide it in four directions: north, south, east and west..." Zhong Hua himself was a master of drawing. After hearing this, his eyes were astonishingly bright. He lifted up his official robe and almost lay on the map, moving his fingers on it, muttering quietly in his mouth. After a long time, Zhong Hua sighed: "It's wonderful... The words of the young master made Zhong suddenly enlightened. You can take the paper and pen at a time, and ask the young master to explain in detail."—

"I dare not, Fang is just a chance." I'm very happy that it can make the map of the Tang Dynasty more accurate and intuitive. What's the point of being a little bit shameless?
