Several people were talking and preparing to return to Yizhou City. At this time, dozens of cavalry came from the north towards here. When they came close, Li Yan saw clearly that it was Jin Daqian who had gone out to find limestone for almost two months.

The hard search of the past two months has made Jin Daqian lose weight and become much darker. After getting off the horse, Jin Daqian hurriedly walked towards Li Yan and said, "Your Highness, the old slave is back, and he lives up to your expectations. He found a lime mine sixty miles east of Yizhou.

Li Yan was happy when he heard this and patted Jin Daqian on the shoulder: "Thank you for your hard work!"

Jin Daqian recalled the life of the past two months like a savage, and felt sad, and said, "This is what the old slave should do. By the way, my highness, I have brought some back. Please take a look." After that, Jin Daqian asked the two servants to carry a bag over and open it in front of Li Yan.

Li Yan glanced at Li Yan's white stone, picked it up and touched it with his hands, be sure that this was limestone, and he was even more happy in his heart, saying, "That's right, this is it."

Kim Daqian finally breathed a sigh of relief after hearing this.

After confirming the limestone, Li Yan asked Jin Daqian to take his servants back to rest. He asked several guards to send the limestone to the research institute, and these are now needed there.

With limestone, the next thing is to mine minerals. From the matter of planting seedlings this time, Li Yan has already felt the problem of artificiality. With the expansion of the Chamber of Commerce of the Tang Dynasty, artificial problems will become more and more prominent. Although Tong Nian has been buying slaves, there are fewer and fewer slaves in the market. This is because the Tang Dynasty has been prosperous and peaceful in recent years, and there is no war. Naturally, there are fewer channels for slaves. Thinking of this, Li Yan had to put his colonial plan on the agenda.

With limestone, Du Pingzhi quickly fired the cement. Now there are kiln factories and limestones, which is not enough to produce large-scale products. With cement, Li Yan's first thought was to build roads first. After all, if you want to be rich, you should first build roads, especially in places like Shu, it is more necessary to build roads.

After agreeing with Shangguan Yi, the first cement road in the Tang Dynasty began to be built in Yizhou City. In fact, it was a cement road, and more strictly speaking, a concrete road. Because the hardness of the pure cement cannot keep up, it is possible to add a certain amount of stones to walk. Li Yan, who is studying engineering, knows this naturally.

The roads in Yizhou City were compact dirt roads, and the slightly better ones were mostly gravel roads, so every rainy day, the roads were still very muddy. Li Yan’s plan was to pave it from Yizhou City first, then extend it to the county town below, and build a few main roads. Of course, all the city in Yizhou City was cement roads, but the county town below was forgot. The project volume was too large and it was unrealistic for Yizhou today, so I could only take it slowly in the future.

The matters of mining limestone mines, firing cement, and levying labor are about to end. It is already May, and winter wheat is also at the harvest season.

Because this batch of winter wheat uses modern production technology throughout the whole process, the yield per mu of winter wheat reached about seven stones, which is 814 kilograms of per mu, which made people envious of others. Not only Wei Tieniu, he was more confident in the crops in his field.

After 20,000 mu of land was taken over, Li Yan became a big grain household. The 140,000 shi of grain forced him to temporarily build more than a dozen grain warehouses, which almost made him feel upset. Because of the cement, all the new grain warehouses were built with sintered bricks and cement, and the floor was covered with concrete. Li Yan also bought waterproof materials specifically to prevent the grain from leaking when it rained and damaged.

After harvesting winter wheat, plums then planted hybrid rice. In autumn, it will be a grain harvest of more than 100,000 stones. In addition to agriculture, the research institute has also made a lot of progress.

With limestone and steelmaking furnaces, the first batch of high-quality molten steel was produced in mid-March. Afterwards, Li Yan began to produce steel to make agricultural tools on a large scale. Li Yan still decided to put agricultural production first. Only when the people have money can consumption follow. In this era, what is fighting in war is money and grain, and nothing can be done without money and grain.

The production of this batch of high-quality steel farm tools was naturally welcomed by the people, and it set off a purchase frenzy in Yizhou for a time, and even attracted many merchants to buy and sell them to other prefectures and counties for sale.

Steel and cement have been solved. Two of the four projects formulated by Li Yan have completed. The rest are steam engines and flintlock guns. Steel is the basis of these two things. Du Pingzhi is now using the materials provided by Li Yan to imitate steam engines. It is not enough to make this thing, but steel is not enough. Rubber is also required. Li Yan will not produce rubber here for the time being. He is just for monopoly, except that he will not let others produce steam engines.

The difficulty of flintlock rifles lies in the production of seamless steel pipes, which is also a process that Li Yan prepared to monopolize. For this reason, he asked the modern machinery factory to produce a batch of hand-made lathes that do not require electricity in order to produce parts of flintlock rifles.

After two months of busyness, Li Yan's immigration application finally came out. He asked Xia Yan to use his relationship in advance to purchase a batch of ancient guns in M ​​Country in the name of purchasing collections. After the acquisition was completed, Li Yan took a plane to M Country, put the guns into the ring, and went to the gun store to buy a semi-automatic pistol with additional bullets. However, although M Country can buy guns freely, there are certain restrictions. In addition to only purchasing semi-automatic weapons, there are also restrictions on the number of bullets. Therefore, Li Yan bought not many bullets, but this is enough for Li Yan to use. After all, he is used for self-defense, not for fighting, and maybe it is not for use at all. It is all for safety. After completing this matter, Li Yan returned to China by plane.

Li Yan made such a big noise in Yizhou for a while, which eventually attracted the attention of all forces. He was constantly talking about him in the court, especially the wheat with a yield of seven stones per mu, which made the whole court explode. However, the news was true, because the news brought by the merchants who traveled to Yizhou and Chang'an were the same. In addition to wheat, the most discussed things in Chang'an were of course the new agricultural tools and the roads being paved in Yizhou. It was easy to say about the road issues, but officials were not interested in this, and those tough agricultural tools aroused the suspicion of many people. Li Yan could produce such good agricultural tools and produce better weapons. This is a big deal.

In the morning court, Li Shimin listened to the court officials tiredly. These days, his ears were filled with the words Li Yan and Yizhou. Among them, some of them praised Li Yan, and some of them had no reason to blame Li Yan, and some of them were suspicious.

"Enough! Since Juer was in Chang'an, you have criticized him, putting the charge of rebellion on him, and now he has been demoted to Yizhou. He has just done a few things that are beneficial to the people's livelihood. You are still so suspicious. Do you really think I am blind? What is Juer doing in Yizhou not for the people, not for the Tang Dynasty?" Li Shimin stood up and said angrily.

"Your Majesty calmed down. The court officials had no malice towards the Sixth Prince. They were just curious about how the Sixth Prince got these superb skills, whether it was winter wheat, steel, or even papermaking, these skills were unprecedented in the Tang Dynasty." Changsun Wuji said.

Li Ke sneered and said, "Father, son ministers have also asked about this. Liulang's things all come from a distant country called Luo An. Because Liulang once saved a Luo Anguo merchant, this Luo Anguo merchant was grateful to Liu Lang and taught some goods and advanced skills to Liu Lang."

"What the third prince said is that recently there have been merchants who claim to be Luo Anguo in Guangzhou. It is said that these merchants are very mysterious, but many people have indeed seen them, and the goods they took were also very strange." Cui Shao said.

Li Shimin pondered for a while, and he also heard that the Luo Anguo merchants appeared in Guangzhou. To be honest, he was also very curious about the current situation in Yizhou, so he said: "Since all the officials are so curious about Yizhou, then follow me to tour Yizhou to see it!"
