After a busy night, Li Yin woke up early the next day and waited outside Li Shimin's palace. When he arrived, Li Tai and Changsun Wuji were already waiting outside the door.
"Fourth Brother, Elder Changsun Ge!" Li Yan, the official vain and slanderer, is very skilled in practice now, even though they don't like it, they still greet each other with a smile.
"Your Highness Sixth!"
"Rokuro!"
The expressions of the two are more sincere than Li Yin, which makes Li Yin secretly say that he has to continue to hone.
"Hey, Liu Lang's complexion is not good, did he not sleep well last night?" After exchanging pleasantries, Li Tai asked with a concerned look.
Li Yin chuckled and said, "Last night, some temporary government affairs were dealt with. The fourth brother and the eldest grandson were exhausted after a long journey. Are you satisfied with your rest last night?"
"Satisfied! Satisfied!" Changsun Wuji said with dark circles under his eyes. Last night, several people talked about going to bed very late.
Li Yin smiled secretly and said nothing. From the moment they entered Yizhou City, their every move was under the surveillance of the hidden guards, and their every move was under the control of Li Yin. Whose territory is Yizhou?
"Liu Lang is really diligent and caring for the people when he is busy late at night, which makes the fourth brother ashamed. By the way, Liu Lang, this is cement." Li Tai pointed to the gray ground on the ground, which is exactly the concrete floor. He wanted to ask last night, but Li Tai I kept talking with Li Shimin, but he didn't interrupt.
Li Yin said: "Exactly, this is the function of cement. It can harden the ground. Even if it rains, it can maintain the firmness and make it easier for vehicles and horses to pass. There are still several sections of roads under construction near Nanshi in Yizhou."
Li Tai and Changsun Wuji met each other and were shocked. Before Li Yin came, he asked the guard to test the hardness of the concrete floor with a sword. The blade of the knife is also rolled.
"What is this cement made of and why is it so hard? Fourth brother really doesn't understand, so please ask Liu Lang to explain it!" As soon as he finished speaking, the door of the palace opened with a "squeak", and then Li Shimin came out.
The officials waiting outside immediately bowed and saluted. Li Shimin waved his hands, looked at Li Yin with a smile, and said, "I'm sorry, this palace is really good."
"As long as the father is satisfied, the minister will be at ease." Li Yin said proudly.
Nodding in satisfaction, when he was on the road last night, he told Li Yin that he was going to see what Li Yin made today, and said, "My son, lead the way, and let me see what other interesting things you have."
Li Yan nodded, and said: "Father, please follow me. The first thing, this son-in-law showed Father the concrete road under his feet."
Li Shimin had already experienced the magic of cement when he entered the city, and he was also very curious about the flat and hard road under his feet.
Li Yin led the southern tour team to Nanshi first, where the craftsmen were working on the cement floor, cement, sand, and stones piled up in a pile. Li Yin brought Li Shimin over, and the craftsmen immediately stopped their work and stood respectfully. On the side, Li Yin stepped forward and grabbed a handful of cement and said to Li Shimin: "Father, this is cement, mixed with water, sand and stones, and mixed together. After three or four days, the hardness will be the same as the road surface just now." gone."
Li Shimin glanced at the flour-like thing, a little unbelievable, and then looked at the servants who were mixing the concrete, "This road is so hard, do you rely on it?"
"Yes, father, don't underestimate it." Li Yin went to the place where the concrete was mixed, picked up a few hard lumps and returned to Li Shimin, and said, "Please look, father, this is the concrete that has not been solidified for a long time." The cement blocks are not hard enough, but after a few days, even a sword will be difficult to chop."
Li Shimin took it, and it took a lot of effort to knead the cement block into powder, and he nodded involuntarily.
After seeing the cement road, Li Yin took Li Shimin to the kiln factory and watched the firing process of cement and the manufacturing process of fired bricks. These are the faces of the officials on the southern tour showing the same face as Xiao Erhei entering the city.
After seeing the kiln, Li Yin then took Li Shimin to the granary. This granary was built on a relatively high hill, surrounded by walls and guarded by guards day and night. Compared with copper coins, grain is real. s things.
Walking from a distance, Li Shimin saw more than a dozen cylindrical objects. When he got closer, he realized that these buildings were very tall, and they were all made of cement and sintered bricks.
Li Yin waved his hand, and a guard immediately ran over and opened the gate made of steel. The whole picture of the granary was also seen clearly by everyone. In the ten-meter-high granary, the wheat stretched from the door to more than ten meters. At the end of Lancang, it was piled up like a small mountain, which was shocking. Changsun Wuji and Li Tai were surprised from ear to ear.
After being surprised, Li Shimin was delighted. He went into the granary and grabbed a handful of wheat from the ground, praising: "This wheat is round and plump, with large grains. It is better than the wheat harvested near Chang'an."
Changsun Wuji nodded, and said: "Yes, Your Majesty, if the entire Tang Dynasty can grow this kind of wheat, wouldn't it be a blessing for all people."
Li Yin really wanted to kick Changsun Wuji's ass. The seeds of the two thousand mu of land would kill him, and he would plant them all in the Tang Dynasty, so he didn't have to do anything, he just specialized in transportation. , Li Yin's original plan was just to ensure the grain planted on his own land. It would be difficult to supply Yizhou, not to mention Datang. His next plan was to let the people of Yizhou use the wheat he harvested as seeds. The wheat seeds he bought are high-yield seeds, not hybrids, so these wheat seeds can be used as seeds. Whoever said that the effect is definitely not as good as the first generation seeds, but they are still much better than the seeds of the Tang Dynasty.
"Yin'er, what do you think?" Li Shimin said, looking at a warehouse of wheat.
Li Yin said: "Father, the elder Changsun Ge's idea is correct, but it is not possible. The reason why the wheat in Min'er's field can be harvested to reach seven stones is not only because of the wheat seeds, but also because of the abundance of fertilizers. The fertile soil, convenient irrigation, and careful care have allowed the yield per mu to reach seven stones."
"Liulang's words are correct, but we can't ignore the factor of this wheat species." Li Tai interjected.
Li Yin said indifferently: "If you don't believe me, the fourth brother can take a batch of wheat with him when he leaves, and we will see the result when it is harvested." Li Yin's words are true. The high yield of wheat is largely due to management, sufficient water and fertilizer Seeds are only one of them in order to produce high yields. If these seeds are planted according to the natural growth pattern of the Tang Dynasty people, it would be good to harvest two or three stones.
Li Yin's magnanimity made Changsun Wuji and Li Tai confused. Is it really as Li Yin said.
Li Shimin pondered for a while, and then said: "Let's look elsewhere!"
…
In the next few days, Li Yin took the officials to see the production of coke, and conducted a steelmaking demonstration on the spot, and showed the movable type that was produced. This movable type is the original clay type, not Li Yin. The printing plate of the printing house, but even this opened Li Shimin's eyes.
After staying in Yizhou for five days, Li Shimin visited Yizhou for five days. After seeing the skills in these workshops, he went to various counties and villages.
After returning from Yangshu Village that day, Li Shimin called Li Yin to the palace, "You should know the reason why my father visited Yizhou this time!"
Li Yin nodded: "They are nothing more than jealous of the skills that my ministers have obtained from Luo Anguo." Then Li Yin took out a booklet, "Father, this booklet records these skills, and my ministers are presenting them now." for you!"
Li Shimin took the brochure: "These are not important, I want to ask you where this Luo Anguo is? Can Datang and this Luo Anguo be able to trade with each other?" Li Shimin was shocked by seeing these skills with his own eyes, but also He became more and more interested in Luo Anguo behind Li Yin.
Relying on Luo Anguo's guise to bluff and deceive for more than a year, Li Yin had already foreseen that one day Li Shimin would pursue this matter, because as more and more modern items are imported, his influence is also increasing, and he is entangled The most important thing is how to answer Li Shimin's question tactfully.
"Father is not just you. I am afraid that many people in the court think so. I just forgive my son for being disrespectful. My son would like to ask Father why the Tang Dynasty did not take the initiative to do business with the barbarians in Yizhou."
"Hmph, how can those barbarians who drink their blood and don't know how to educate them deserve to do business with the Tang Dynasty." Li Shimin said disdainfully.
Li Yin laughed and said: "That's right, how the father looks at the barbarians in the deep mountains, this is how Luo Anguo looks at the Tang Dynasty. For them, there is nothing in the Tang Dynasty that they need. Why should they come here all the way?" .”
"Arrogance, the Tang Dynasty is the kingdom of heaven, and all nations come to court..." Li Shimin was furious, his face was purple, and it was very scary, but he fell down just halfway through the sentence. The various things and skills Li Min brought were enough. Proved, thinking of this, he couldn't help but snorted coldly and stopped talking.
Li Yin secretly heaved a sigh of relief, and continued: "If it wasn't for my ministers who once rescued a Luo Anguo businessman, they would have disdain to associate with him at all, and it is precisely because of this that Yin'er can get some inferior skills from them And commodities, I know that they look down on them, but I still endure humiliation and try to please them in every possible way, in order to get some skills and products that are beneficial to Datang, but even so, I am still jealous by the courtiers, a Like a hungry tiger, I wish I could share it and eat it, instead of doing this, I can just cut off contact with Luo Anguo, and everyone will be clean from now on." At the end of the speech, Li Yin was full of tears, very sad look.
Li Shimin hurriedly said: "Min'er, don't be arrogant. Although my father is also angry with Luo Anguo's arrogance, I have to say that their skills are really useful to Tang. Wan besieged Chang'an, and his father endured humiliation and gave him money in exchange for a few years of peaceful life. In the end, he was still wiped out. Now Luo Anguo is just like Jieli back then. You should bear the humiliation too. After all, dealing with them is very important to Tang Dynasty It's all about benefit and nothing harm."
"Yes, father, my son originally wanted to obtain these skills from Luo Anguo and slowly study them in Yizhou, turning this Yizhou into a port for exchanges with Luo Anguo. When Yizhou is prosperous, skills and products will naturally be sent to Yizhou. Other places in Datang, this is called radiation economy."
"Radiation economy?" Li Shimin repeated.
"Yes, just like this torch, the flame in the center is bright, and the light can reach far away. I am planning to build Yizhou into the center of this torch, and use the flame from Luo'an to illuminate the land of Shu first. Then to the north, and then the entire Tang Dynasty." Li Yin made a bold statement, and his words were not shocking.
