Wei Tieniu, who was busy, was taken aback by the swarming businessmen, and after figuring out the purpose of these businessmen, Wei Tieniuughed almost to the back of his ears, and hurriedly greeted these businessmen.


    Li Yin stayed at the fair for a while and then went back. The protagonist of today’s fair should be Wei Tieniu. Li Yin nned to let Yangshu Vige sell the potatoes first. Some of them are sold, and the others can be used as military rations, and some of them can be eaten by the students of the college, which saves buying some vegetables.


    The exhibitionsted for about two hours. Every businessman tasted the taste of boiled potatoes. It was very novel to them who tasted this vegetable for the first time. Besides boiled potatoes, the fried potatoester made them even more delicious. Work up an appetite.


    After the fair was over, Wei Tieniu led the merchants to the field of Yangshu Vige. When these merchants saw a field of potatoes, they immediately gathered around to discuss purchase matters, especially those small traders who were very positive, because the potatoes were cheap and Selling fresh vegetables to other ces and selling them to rich families can definitely make a pot of gold.


    Seeing so many merchantsing, the vigers of Yangshu Vige felt reassured, and sold the harvested potatoes to the merchants one after another. The price was ten cents a bucket. This was the price set by Li Yin, and it was also to avoid market chaos that would cause potato Slow sales, this is not worth the candle.


    At the same time, the news about potatoes was also published in the Datang Business Daily, which wrote how to eat and store potatoes, so that these businessmen can also have an understanding, so as to avoid unnecessary losses.


    After five or six days of busy work, the potatoes in Yangshu Vige were basically sold out. Li Min released another batch of his own potatoes, and he kept the rest in a dry warehouse to prevent the potatoes from sprouting.


    "Your Highness, what should we nt next?" Wei Tieniu asked when Li Yin went to the countryside to inspect the potato sales in Yangshu Vige, and the other vigers of Yangshu Vige who surrounded him also looked at Li Yin expectantly. After this incident, they no longer had any doubts about Li Yin, and they all looked at Li Yin with fanatical eyes.


    This time the potatoes were sold, and each of them basically sold them for two bucks per acre ofnd. On average in the entire Yangshu Vige, each family has an ie of hundreds of thousands of dors. This is an astronomical figure for them. They have changed from a poor ss to a petty bourgeoisie overnight. Can you not be grateful to Li Yin?


    Li Yin thought for a while, and now the agriculture in Yizhou ispletely controlled by him. At present, it is not suitable to nt too many vegetables. Food is the most important thing. Let them earn a little money for a year. "Grow rice."


    "Rice?" Li Yin said. Everyone was a little disappointed.


    Li Yin said: "Can potatoes be eaten as a meal? This rice is worthless, but it can fill the stomach. I will nt potatoes tomorrow in spring. Everything is out of season now."


    "Okay, Your Highness. We''ll listen to you." Wei Tieniu understands that the way to make money is in Li Yin''s hands. Li Yin lets them make money, and they can make money. If Li Yin is upset and won''t let them nt potatoes tomorrow, then It was toote for them to cry, "I''ll let people sow seeds to raise rice seedlings."


    "There is no need to nt rice seedlings." Li Yin said. This time he transported arge amount of high-yield rice seeds, and the rice seeds can be directly sprinkled on the fields, eliminating the need for the step of cultivating rice seedlings.


    Wei Tieniu touched the back of his head and said, "How do you grow rice without growing rice seedlings?"


    "Just go and buy the seeds. Someone will teach you how to nt them. This kind of rice is not the kind of rice you nted before. As long as you take good care of an acre ofnd, you can harvest about seven shi."


    "Seven stones? Your Highness, is it the same yield as winter wheat?" Wei Tieniu asked in surprise.


    Li Yin nodded and said, "Yes, you are satisfied now."


    "Satisfied. Satisfied!" The vigersughed and echoed.


    Leaving Yangshu Vige, Li Yin went to other prefectures and counties to inspect. The rice of the first season wille down, and then the rice of the second season wille. This time, because of the incident in Yangshu Vige, the people''s trust in Li Yin has risen sharply. Li Yin ns to use this opportunity to promote high-yield rice throughout Yizhou, and then nt winter wheat in winter. The food problem will be basically solved. After the nting habit is formed, Chengdu will not be short of food. Set up a grain management station and buy up the grain reserves of the people. Are you afraid that there will be no military food by then?


    As for other vegetables and fruits, he is nning to promote them as a production base. For example, Yangshu Vige is a potato production base, while other ces are grapes. As a result of overproduction, not only can''t make money, but also lose money. After the real market mechanism is perfected, he will slowly let go.


    Agriculture is gradually on the right track, allowing Li Yin to solve the most basic stomach problems of the people in Yizhou. The next step is to make the people better off, but his current task is the entire Chengdu government, and it is still a heavy responsibility. Far, he needs to keep working hard.


    After returning from inspections in various states and counties, Li Yin went to Taoyuan. With the mobile power station, theputer, the projector, and the teaching video, it is time to wash the brains of these indigenous scientists.


    Let the servants transport four of the eight mobile power stations to Taoyuan, and Li Yin bought arge number of wire sockets. He has toy the wires himself. In order to educate him, he has to sacrifice his time drinking tea and working with beautiful women. There is really no way He is the only one who knows what to do, but fortunately, Li Min is an engineering student, and he has a good understanding of these hydropower lines, otherwise he must be caught blind again.


    Afterying the wiring, Li Yan sent someone to bring theputer and projector. These things have been debugged in modern times. He only needs to remember to insert the plug in the corresponding ce, so it is very convenient.


    After finishing the equipment, he divided the teaching videos into categories, such as chemistry, physics, mathematics, etc., in the order of teaching so that there will be no mistakes when ying.


    Li Yin pulled Tong Yu, Du Zhiping and Guo Xianyuan to study with him during the whole process of operation. The three of them can be considered as the person in charge of Taoyuan. They still have toe.


    "Your Highness, is this okay?" In therge public ssroom of the research institute, Li Yin and Tong Yu stood on the podium, and there were more than 3,000 people sitting under them. These 3,000 people were carefully selected from all over the Tang Dynasty. The indigenous scientists who came to Taoyuan used to be ordinary craftsmen in Taoyuan, but now they are all students.


    Just now Li Yin asked Tong Yu to go through the steps of ying the video by himself, after practicing it more than a dozen times. Tong Yu has basically mastered it.


    Li Yin nodded and said: "It''s ok!" He looked at No. 3,000 people and said: "There will be some images next, don''t panic. Don''t be afraid, these things are illusions, not demons, nor ghosts, let alone Dao It is not magic, but a real scientific phenomenon, just like the moon in the sky reflected in the water."


    Thousands of people looked at Li Yin and listened to Li Yin''s narration, but there were already a lot of strange things in Taoyuan, and their hearts had be much stronger.


    Li Yin finished speaking. Click to y the video, a female teacher holding a book suddenly appeared on the screen, and at the same time, a transliterated electronic voice sounded from the speaker, "Now we start the first ss of mathematics, and this number is read one..."


    Suddenly, a person appeared on the screen. Tong Yu was so frightened that he backed away again and again, and the people below all opened their mouths in surprise, other machines and the like were fine, why was there a person inside.


    Li Yin lowered his voice, picked up the microphone and said, "Don''t panic, it''s all fake, this person doesn''t really exist. Look carefully." Li Yin put his hand on the screen and shook it, and the image also changed continuously , Li Yin was very satisfied with their reaction, and he was Amitabha if he didn''t kneel down and shout for gods.


    Tong Yu recovered from the panic at the beginning, he was a little embarrassed. Following Li Yin''s example, he also put his hand on the screen, and it was the screen that he touched, and the shadow was reflected on his hand. He was relieved, and asked in surprise, "What''s going on, Your Highness?"


    This question is not exined clearly. Li Yin knew that they would not feel at ease in the ss, but they would not be able to understand too profound theories, so Li Yin changed a disc, which was a teaching video for the object ss, about optical projection.


    Li Yan had prepared for a long time, he picked up a square cardboard box, the box was sealed on all sides, except for a small hole at one end, and translucent paper at the other end.


    The teaching video started to y, Li Yin cooperated with the teaching video, and began to exin what is light and the characteristics of light, then talked about the projection of light, and then talked about how to record the projection of light, and the projection of light is also demonstrated in the video For the experiment, Li Yin tried to exin it as thoroughly as possible, and the exnation of the projection of the projector equipment also appearedter.


    After the video was yed, Li Yin held the box in his hand, asked Tong Yu to light a candle, pointed the small hole in the box at the burning candle, and said to the people below: "Who wants toe up and see what happened?"


    The small box that Li Yin is holding is used for the simplest experiments in optics. The fireworks of the candle will be reflected on the translucent paper through the small hole in the middle.


    The exnation just now gave the people below a basic understanding. After waiting for a while, Li Yin bravely walked up to the podium. He took the box in Li Yin''s hand and pointed it at the candle, seeing the projection on the paper. It seems to have realized something.


    As this person came to the stage, more and more people began to watch the scene, and some directly touched the screen, and finally understood that the screen was an image, not a real person.


    Removing this obstacle, Li Yin arranged the curriculum, and assigned each person to different sses ording to their different research directions, but the two courses of mathematics and Chinese were still public courses and had to be studied.


    Using video teaching can naturally input modern knowledge, but this method is rtively rigid, and these people will inevitably have some questions, and the people in the video cannot answer these questions immediately, so Li Yin asked Tong Yu to select The recorder, write down the questions that you don''t understand on weekdays, and after a few days, Li Yin wille over and answer them in person.


    In order to keep abreast of these people''s mastery of knowledge, Li Yin ns to study contemporary education and use exams to test their learning status. Those who pass the grades are encouraged, and those who fail to pass the grades are pulled out to y the board. He doesn''t care what it is Corporal punishment education, for him, is now the key to teaching good students.
