Twenty days later!

Li Yu finally found the rubber forest that the Dragon and Phoenix Empire urgently needed in South America.

After Princess Yicheng came out of the space, she saw the huge rubber forest and shook her head and said, "Is this the rubber tree? It doesn't look magical?"

"You are wrong. These are all treasures. Rubber is the basic raw material of the rubber industry and is widely used to make tires, rubber, tape, cables and various other rubber products. In the future, our Longfeng Empire's technology development will be used in many places." Li Yu looked at this rubber forest happily and introduced the widespread role of rubber.

After hearing Li Yu's introduction to the rubber tree, Princess Yicheng said in surprise: "These trees look bad, and I didn't expect that the latex flowing out of the tree would have such great use?"

"Haha! When you saw oil a few days ago, didn't you still think that it was useless to be black? Later, did you know that oil is full of treasure?" Li Yu smiled and joked about Princess Yicheng.

"Hehe, you laughed at me for not understanding technology again. I ignore you. I want to go there with Li Chun for a while now. You can stay and dig these tens of thousands of acres of rubber trees by yourself!" Princess Yicheng glanced at the entire rubber forest and giggled.

After Li Yu watched Princess Yicheng and Li Chun leave, he recruited Hong Ling, divided the 100,000 acres of rubber forests one by one, and moved the whole space into the space. Most of the rubber trees in the entire rubber forest can be directly cut into rubber, but they don’t need to grow for a few more years.

As soon as we moved more than 100,000 acres of rubber trees into the space, we saw Princess Yicheng and Li Chun grab a few turkeys and came back happily.

"Young Master, let's eat these birds at noon. Look, they are fat and big." Princess Yicheng looked excited and raised the huge turkey for Li Yu to see.

"What you are catching is a turkey, but it is not a bird, and these turkeys are only available in the Americas." Li Yu immediately corrected it.

After hearing Li Yu's introduction, Princess Yicheng immediately said: "There is a large pond over there full of turkeys. How about we grab them into the space?"

"Of course! I've caught them all. This turkey is not only fresh and plump, but also has a high lean meat rate. It's also rich in protein, but it's a good thing." Li Yu smiled and said, "From then on, the people of our Dragon and Phoenix Empire have a good taste, and there is another delicious dish on the table."

"Then let's go!" Princess Yicheng heard this and hurriedly urged Li Yu to go over and catch the turkey as soon as possible.

When Li Yu and Princess Yicheng came to a small lake, they saw that the entire lake was densely filled with turkeys. Because there was no human culling, the turkeys were about to become disaster now.

Li Yu did not let go of any of the turkeys near the entire lake. All of them were waved by Li Yu's hand and put them in groups of them into the space...

Along the way in America, Li Yu saw all the useful species and was swept into the space by Li Yu before leaving America.

After returning to the Central Plains, he ran to the Western Regions to find wild cotton, released hundreds of thousands of people again, and collected large areas of wild cotton on the wasteland...

…………

Three months later, the Tang Dynasty.

"Yuanyuan, did Du Mirou make the current printing factory good? Look at the "Three Character Classic", "Hundred Family Surnames", "Disciple Views"... These textbooks are printed really well." Li Yu looked at the huge factory with semi-automated printing machines and printed books, and was very satisfied.

Princess Yicheng said proudly: "Of course, I don't want the next generation of our Dragon and Phoenix Empire to be illiterate."

"Hey! Even color printing can be printed?" Li Yu picked up the printed color book and was startled again.

"One-forming is not possible yet. It is only a few processes before printing it. However, the picture is printed well, but it is just a little slower." Princess Yicheng shook her head, not satisfied.

After reading the book, Li Yu asked again: "Have you prepared the mirror I want?"

"The technology of flat glass production is not yet mature, and it is not too big at present. The main reason is that workers cannot control the production process. The glass mirrors made now can only be about three feet in size."

"It is not easy to be able to produce such a large one. The production process has not been explored for more than a few years and it is impossible to mature. When the production process matures in the future, it can be made into a large one, I will change it..." Li Yu waved his hand and didn't care.

"I originally said that it has been out for more than ten days, but now it has been out for more than three months. I haven't been with Fei'er for the New Year this year. Alas!! I wonder why this sister would blame her brother for not keeping her word?" Li Yu left the space and looked at the direction of home and sighed, talking to himself.

Tai Chi Hall of the Imperial Palace!

In the Tai Chi Palace, a middle-aged and elderly man wearing a bright yellow dragon robe sat behind the dragon table with a smile, enjoying singing and dancing, and tapping several tables with his fingers along with the music.

This person was Li Yuan, the founding emperor of the Tang Dynasty. Li Yuan was nearly fifty years old, with a square face and a wide mouth and a rich face, and a majesty that ruled the world.

After the dance ended, a group of beautiful dancers and a pretty singer walked forward in small steps to salute Li Yuan. However, Li Yuan opened his eyes and smiled at the elderly man next to him and asked, "Pei Qing, how do you look at the singing and dancing performance today?"

"I think it's really good! It's no different from the singing and dancing in Jinyang Palace before." The person who spoke was an elderly man with a white beard and fluttering look, looking kind and kind.

He was able to watch singing and dancing with Li Yuan and speak so casually, and Li Yuan was so kind to him. This person was Li Yuan's best friend and Pei Ji, the first prime minister of the Tang Dynasty.

"It's not necessarily true! I heard that last year, someone sang a grand song "Dream Back to Chang'an" outside Chang'an City, and now he has shocked the whole of Chang'an." Li Yuan smiled and shook his head.

"Your Majesty, you mean to use suture technique to save Sanniang's scholar named Li Yu! Later, he invented the method of boiling salt and stir-frying steel, and wrote the "Three Character Classic" and "Hundred Family Surnames"..." Pei Ji asked after talking about Li Yu's achievements.

"It's him, you see, this guy wrote an article. He named it a novel, and it used vernacular Chinese. It looks quite interesting, so you can take a look." Li Yuan asked the palace maid to give the manuscript to Pei Ji.

A strange dream once shocked the autumn rain

The soul of a hero is like a mountain of thousands of miles

"How can I say this guy's limerick poem? I'll take a look later." Pei Ji looked at Li Yuan for a while, and the expression on his face became excited.

"Pei Qing! Do you understand?" Li Yuan smiled, with a look of relief on his face.

"Yes, Your Majesty, the symbols used between the lines play the role of breaking sentences. You can understand what it means at a glance, and you won't read it for many people. Many people understand it differently. I think this is simply an innovation. In addition, the court will not cause any errors in understanding in the future."

After explaining the benefits of punctuation marks, Pei Ji quickly stood up and saluted, and said, "I will ask Your Majesty to immediately popularize this symbol to the world."

"Okay, since even Pei Qing has agreed, then I will issue official documents to popularize the world!" Li Yuan laughed and said when he heard this.

Pei Ji immediately asked, "Your Majesty, Li Yu's contribution to the past treatment of Sanniang, and now he has made so many meritorious masters, how can Your Majesty reward him?"

"Oh! It's more than enough to reward county men just for salt making. In addition, I've treated Sanniang, but this kid is so bold that he beat Chai Shao. It's not okay to not give a explanation to the Chai family! I have to feel wronged him." Li Yuan shook his head and said, "But Sanniang means that this kid is not interested in being an official, so he asked me to reward him with some land and gold and silver. At present, he can only calm the anger of the Chai family for the time being, and then find a way to serve the court in the future."

As soon as Li Yuan finished speaking, he changed his tone and continued, "But this man has a bad background and doesn't seem to be very good. However, being able to make such great contributions to the court and even save Sanniang's life is considered young and promising, but he is too arrogant. Do he think that he dares to beat important officials of the court with those contributions?"

"Your Majesty blamed Li Yu for his mistakes. According to the person who reported that the prince-consort led his subordinates to rush around the streets. Li Yu couldn't stand it, so he had both sides wrong with the prince-consort." Pei Ji said unbiasedly.

"Although this is the case, it is not a good thing to be successful at a young age, so I think it's better to leave him alone for a few years, just give the Chai family an explanation. It's not too late to make plans after his mind is stable, so I will do it according to Sanniang's wishes." Li Yuan's disposal was obviously biased towards the Chai family.

If Li Yu heard this, he would only sneer at it. I want your Li Yuan throne, but he can only grasp it with his hands. He would not care at all, let alone take it to heart.

However, it can be seen from this that the emperor Li Yuan was a kind and righteous person. The contribution of Li Yu to make salt alone could double the fiscal revenue of the Tang Dynasty every year, let alone solve the problem of the difficulty of people eating salt.
