"I am already quite old and can do any shameless things, so don't ask me any more questions."

Zhang Yang clasped his hands and sighed, "Is this the benefit of being older?"

Li Yuan stroked his beard and said: "I recently sat down with Sun Simiao to discuss Taoism. There are many fields. I can also be a Taoist priest."

"I envy you, old man."

"What do you envy me for?"

"You can always find an ideal, another way, or, if your son is the emperor, who dares to mess with you?" Zhang Yang put his arm on Li Yuan's shoulder.

These are the shoulders of the Supreme Emperor, no one dares to rest on them casually.

"Just because my son is the emperor, I can't do whatever I want. Since Erlang came to the throne, the palace has been a prison for me. I never want to go back."

"While saying that it's shameful for Prince Hejian to stay away from home for a year and a half, I still don't want to return to the palace. It's really shameless."

"Hahaha." Li Yuan smiled heartily.

"Sometimes I really want to invite you back."

"You think I'm eating and drinking for free? Are you tired of me?"

"of course not."

"Hahaha..." Li Yuan laughed again.

Zhang Yang scratched his ears, unable to get used to the wild laughter.

Li Yuan sighed: "It was not easy for Yue'er when she was a child. I don't know what she thought about falling in love with you. At that time, everyone said that she would not survive to adulthood, so she was left alone. Let her feel more comfortable in the last year. Who can

I know your boy cured her."

"I understand."

"You said you understand with a serious face. What do you understand?"

"The Emperor thinks that I have taken advantage, and now he wants to take it back." Zhang Yang frowned and said, "Actually, it doesn't have to be like this. You are my wife's grandfather. Even if the emperor in the palace doesn't care about you, as your grandson-in-law

I should also support you, including the Hejian County Prince, we are one family."

Li Yuan nodded heavily, "A family..."

Looking in the direction of Chang'an, Li Yuan shook his head and said, "Not everyone will think like you."

Zhang Yang smiled indifferently and said in confusion: "I heard that the prince's health is also quite weak. Recently I observed that the prince's complexion is very bad."

"Chengqian was often sick when he was a child, because Erlang was away from home all year round. At that time, Guanyin's maid did not take good care of her fetus and was often worried about her. It's my fault."

Speaking of what happened back then, Li Yuan lost interest and got up and walked to Sun Simiao's medical clinic.

What happened back then is a scar, and I should rarely mention it in front of his old man in the future.

That girl always stood guard in front of Li Yue's study. She didn't say anything, just saluted respectfully, took out the key and unlocked the study.

It seems like she often stays here and doesn't let anyone else in.

Opening the door, Zhang Yang walked into the study. There was nothing important here, but all the important knowledge was kept in his mind.

There is a huge map hanging on the wall, which depicts the entire Central Plains from southwest to north.

Different from the maps outside, after reading the books these days, Li Yue improved this map a lot according to the records in various classics. Compared with the simple annotations on other maps of the Tang Dynasty, this map is much more detailed.

He took out a volume of books from Li Yue's schoolbag. He had read several volumes of geography in Chongwen Hall, and recalled his fragmentary memories in later generations and made a lot of notes and annotations.

Especially the Western Region, which is a vast and sparsely populated place.

To the west of Gaochang, what is now the Western Turks, is divided into Northern Xinjiang and Southern Xinjiang.

The climate in southern Xinjiang is better, more suitable for growing fruits and melons, and is also suitable for grazing. Agriculture is basically the main area.

The northern Xinjiang is desolate, and that area is more suitable for growing cotton. The Yinli River Valley is the best producing area for cotton cultivation.

Zhang Yang frowned and looked at the map for a long time. The Western Region should not be so small.

I used my wife's inkstone to grind the ink, then I drew an arc further west, and then another arc to the northeast. After taking a closer look, I felt something was wrong, so I added a few more strokes.

Just as she was thinking hard, Li Yue walked into the study. She looked at the map and wondered: "Why did your husband draw a chicken on the map?"

"chicken?"

"Yes, like a chicken."

Zhang Yang scratched his head, "I think it's more comfortable to watch like this, don't you think so?"

Li Yue smiled softly, "If this is how my husband considers the territory, I think it can be bigger. My husband has also said that the world is very big before."

"That's right, our ambitions can be bigger."

The girl stood respectfully outside the door, and a sloppy girl ran over, "Sister, the boy wants us to catch wild boars together."

The girl lowered her head and said, "I can't play around with you."

"Why?"

"Because I am no longer the same as you."

The sloppy girl said with a sly look on her face, "Then are you just going to stand here like this?"

"Let's go play." Li Yue's voice came from the study.

As if receiving an order, this girl followed this sloppy girl and left.

Li Yue looked at the Western Regions, "The Western Regions are very vast. I think back to the Han Dynasty when Huo Qubing swept across the Western Regions and the North with a single horse. Just looking at it makes people admire him."

Zhang Yang drew a circle west of Gaochang and said, "Let's take this land too."

"Is there anything special about this land?"

"This is a good place to grow cotton. Of course, apart from here, Longyou is also a good place to grow cotton. But I'm afraid your father won't agree to changing the land to cotton."

"We can figure it out slowly."

March in Chang'an City is a good time for spring outings.

Travelers can be seen everywhere in Guanzhong, and the couple goes out less and less often.

Seeing that Li Tai was doing nothing all day long, he had trouble with the fish last time, so I'm afraid that he would have trouble with someone else this time. He is a money tree, but he can't grow crooked.

He grabbed Li Tai and came to the house to do some hard work, helping with sawing wood and mortar.

Sweating profusely while working, Li Tai wiped the sweat from his forehead and said, "Brother-in-law, isn't this roof very good? Why does it need to be raised higher? It will exceed the limit."

Zhang Yang repaired the bricks one by one, "I have read a lot of books these days, and also studied some classics from the Yushitai and the Ministry of Punishments. My building is only three stories high, so it is not considered over the limit."

Li Tai frowned and said: "The records in the classics are one thing, but as long as the house is raised, people will inevitably have reasons to deal with you. There is not much difference between one-story height and two-story height."

"I think you just don't want to work. You don't want to go beyond the rules. Those powerful people are more or less above the rules. You can't just write a few sentences and expose it in the court."

Li Xiaogong's voice is very open and clear, and it is comfortable to listen to such words.

Seeing the little fat man's aggrieved look, Zhang Yang patted him on the shoulder and said, "Your Highness, King Wei, you should persevere in your weight loss career, and your health should come first."

"I haven't had a donut yet! It's been a year!"

"You can't rush this kind of delicacy, you can eat it sooner or later." Zhang Yang pointed to the stones on the side, "Please bring those stones over."

"Ouch..."

He talks tough, but he just goes to work obediently.

The paper issue can also be put on hold for the time being. The two aunts have dried nearly a hundred kilograms of paper in their warehouse. The ink problem has not been solved yet, and the oil has not been delivered. The printing business has been put on hold for the time being.

After returning to Chang'an City, Li Xiaogong was not in high spirits.

He is also a eldest man, the children in his family are almost grown up, and he is still a prince of a county. He has a home in Chang'an City and never returns home. It is inevitable that his family will gossip when he hangs out all day.

The beams on the roof have already been erected, and the aunts are very quick in their work. Once the platform is built, it can be completed within half a month.

Li Xiaogong looked at the drawings in front of him, "What do you think are the benefits of this shower thing?"

Zhang Yang grinned and said, "It has endless uses."

Li Xiaogong frowned and looked at the drawings, pretending to be very knowledgeable, "It has endless uses? How is it different from our daily bathing?"

"They all use water, so there doesn't seem to be much difference."

"How come you, a country boy, have so much attention to detail?"

Li Xiaogong picked up the drawing, put it down, and then thought about it again and again.

After frowning for a while, Li Xiaogong pointed at a few words and asked, "What does this mean?"

Zhang Yang sat cross-legged on the chair and took a sip of tea. "This is the ratio. Now it is a hundred to one ratio."

Li Xiaogong tugged at the beard on his chin. After a while, he gave up trying to understand this kind of drawing. Then he stood up and touched the back of his head, gasping in pain.

A large piece of his hair was shaved, and the redness and swelling had not gone away yet. Sun Simiao just used some medicinal materials to reduce swelling and simply bandaged it.

"Still hurts?" Zhang Yang asked while drinking tea.

"I still have bouts of pain, but it's much better than the past two days." Li Xiaogong touched the back of his head, "You kid, don't stop me."

Zhang Yang said: "I don't want to get involved in your family affairs."
