In order to see more of the "excellent" expression changes of this eternal emperor, Li Chengqian decided to add some more information to him.

"I haven't finished talking yet. Old man, you have been fighting in the south for many years. You should have a headache about the night blindness of soldiers, right?"

"Hmm? Do you have a solution?"

"Of course, the reason why people cannot see it at night is because their nutrition cannot keep up. Look at the big fish and meat all day long. Who will not see it at night? Grassland hurts to grazing cattle and sheep, there will definitely be goat milk, milk, and even horse milk. These milks are made into cheese, milk lumps, etc., eating more can solve night blindness. Is it magical?"

Well, this half-baked time traveler doesn’t know at all that the main effect of dairy products is calcium supplementation, so he dares to speak nonsense. As for whether it can be treated with night blindness... Long-term consumption may be possible, because dairy products also contain vitamin A, and night blindness basically lacks this trace element.

"Cheese? Milk bumps?"

"Now you are thinking about it, is this grassland a bitter and cold place, or is it full of gold?" Li Chengqian looked at His Majesty Li Er with a smug face - to be precise, he looked at His Majesty Li Er with his nostrils, so...

"Oh, old man, you can burn the bridge when you cross the river!"

"Hmph, how can you sit on my dragon case? I have never sat on it myself!"

"I'm ashamed, that table was made by me. What kind of dragon case is just a long table that breaks willow wood? How rare!"

"Bang!"

"Why do you hit me again? Do children have no human rights?"

"Get over and write down what you just said, especially the method of making wool clothes, the method of preserving mutton, and the cheese, all of them!"

"Just write it, what's the most fierce!" Li Chengqian, who was so scared by His Majesty Li Er's eyes, obediently walked to the "Dragon Case", sat in His Majesty Li Er's position and began to "write quickly"!

Thanks to countless time travel novels in later generations, thanks to the omnipotent Du Niang Encyclopedia, let Li Chengqian know how to use wool to weave cloth, how to use fresh milk to make cheese, and how to marinate meat...

"Bang!"

"Why do you hit me again?" Li Chengqian turned his head and looked at me with glaring!

His Majesty Li Er had a sharp look, "I asked you to practice calligraphy, so how did you practice it?"

Li Chengqian was embarrassed in an instant and smiled embarrassedly: "Hehe, this...that..."

"snort!"

With a cold snorkeling, Li Chengqian didn't need to explain and continued to write obediently.

...

Not long after the sun rose in the morning, he arrived at His Majesty Li Er's Liangyi Hall, until the sun sets in the west, Li Chengqian has been writing and painting.

His Majesty Li Er has been standing aside and grinding for him... By the way, he criticized his calligraphy from time to time and supervised whether he was lazy.

"Old man, you can't abuse children like this. Can you write it tomorrow?"

"What do you think?"

"Wuwuwu, Mom, I miss you so much, come and save me!" This sentence was Li Chengqian's inner thoughts, and he didn't dare to say it... The back of his head was still aching, and this was the result of shouting that he had saved his mother!

Perhaps it was because of the mother and son who were in love, Li Chengqian shouted countless times in his heart, but he actually summoned his mother, Empress Changsun...

"Second brother, it's dark, it's time to have supper."

"Guanyin Bi, why are you here? You should rest well and be careful." His Majesty Li Er hurriedly ran over happily when he saw his wife.

"It's not a big deal, it's only four months."

That's right, Empress Changsun pregnant with Li Chengqian again... How did you think Li Chengqian knew he was a sister? Of course, he calculated... Baidu Encyclopedia: Princess Chengyang, the daughter of Emperor Taizong of Tang and Empress Changsun, whose birth date is unknown, probably around the four years of Zhenguan...

"Cough cough..." Li Chengqian saw two shameless people showing their love, completely ignored him, the "motherland flower" that had been destroyed for a day, and could only give him a dry cough and give him a reminder.

"Gao Ming is here too? What are you writing?" Empress Changsun pretended to be surprised.

Li Chengqian curled his lips secretly and said to himself: If you don’t know that I am here, I will swallow the inkstone in front of me!

"Your mother is asking you something!" Seeing that Li Chengqian didn't sound for a long time, His Majesty Li Er couldn't help but scold him loudly.

Li Chengqian looked at His Majesty Li Er with a grievance and said, "Father, don't you want me to concentrate on writing and not talk?"

"snort!"

Without too many words, Li Chengqian dared not be humble, and said to Empress Changsun with a smirk, "My mother, I am writing a major national plan. If I implement this plan according to my plan, not only can our Tang Dynasty eliminate the disaster of grasslands forever, but also let the people of our Tang Dynasty solve the problem of food and clothing, and it is not an out of reach for the whole people to achieve a well-off life. More importantly, I can make a lot of money. I have already thought about it, find someone to buy it for thousands of acres of grasslands, and then find someone to help us graze, and open another textile factory and a food factory..."

Well, that's right, Li Chengqian was complacent again and was soon strongly suppressed by His Majesty Li Er!

"Gee... Smile brat, just count you, you can tell everything you have. "Empress Changsun smiled and looked at her son with aggrieved face and her husband with a slight pride on her face.

"What I said is true."

"My mother didn't say what you said was fake. Okay, don't write it first, eat the food first, are you hungry?"

Otherwise, it would be better to say that only mothers in the world? Li Chengqian could understand the meaning of this sentence at any moment better than now.

"Long live mom!"

When His Majesty Li Er saw Li Chengqian who had started to be selfless again, he instinctively wanted to give him a blow, but was grabbed by Queen Changsun without any trace.

"Second brother, you've been working hard for a day. Let's have a meal and have some leisure time. I've made your favorite lotus seed soup."

"Oh, Guanyin maid said that if you are pregnant, don't cook anymore. Why don't you listen? These damn things won't persuade you!"

"Okay, second brother, don't get angry. How dare the palace maids in the kitchen stop me? Let's go and eat, it'll be cold in a while."

"Okay, go, go, come, I will support you, be careful of the steps..."

Li Chengqian followed the couple speechlessly, full of resentment.
