Several people were talking about going back to Yizhou City. At this moment, dozens of horsemen came from the north. When they approached, Li Yin could see clearly who was coming. It was Jin Daqian who had gone out to search for limestone for nearly two months.

After nearly two months of hard searching, Jin Daqian lost a lot of weight and became darker. After getting off his horse, Jin Daqian hurriedly walked towards Li Yin and said, "Your Highness, the old slave is back. As expected by His Highness, a lime mine was found sixty miles east of Yizhou.

   Li Yin was overjoyed when he heard the words, and patted Jin Daqian on the shoulder: "Thank you for your hard work!"

Jin Daqian recalled his life like a savage for the past two months, feeling sore in his heart, and said: "This is what the old slave should do. By the way, Your Highness, the old slave brought back some, please have a look." After finishing speaking, Jin Daqian Daqian asked two servants to carry a bag and opened it in front of Li Yin.

  Li Yin glanced at Li Yin's white stone, picked it up and touched it with his hand, convinced that it was limestone, and felt even more joyful, saying: "That's right, this is it."

  Jin Daqian finally heaved a sigh of relief.

   After confirming the limestone, Li Yin asked Jin Daqian to take the servants back to rest, and he asked a few guards to deliver the limestone to the research institute, which is needed there now.

With the limestone, the next thing is to mine the mineral deposits. From the matter of planting seedlings this time, Li Min has already felt the artificial problem. With the step-by-step expansion of the Shengtang Chamber of Commerce, the artificial problem will become more and more prominent. I have been buying slaves for many years, but there are fewer and fewer slaves in the market. This is because in the past few years, the Tang Dynasty has been peaceful and peaceful, and there has been no war. Naturally, there are fewer channels to produce slaves. Thinking of this, Li Yin had to sell himself The colonization plan of the country was put on the agenda.

With limestone, Du Pingzhi quickly fired cement. Now that there are kilns and limestone, it is just a matter of large-scale production. With cement, Li Yin's first thought is of course to build roads first. Fu first built roads, especially in places like Shu, it was even more necessary to build roads.

After an agreement with Shangguanyi, the first cement road in Datang began to be built in Yizhou City. In fact, it is a cement road, but more strictly speaking, it is a concrete road. Because the hardness of pure cement cannot keep up, it can only be done by adding a certain amount of stones. Li Yin is an engineering student and knows this.

The roads in Yizhou City used to be rammed dirt roads, and the better ones were at most gravel roads, so every time it rained, the roads were still very muddy. Li Yin’s plan was to pave the roads from Yizhou City first, and then move to the city. The county below is extended, and a few main roads are built. Of course, all the roads in Yizhou City are cement roads, but the county below is fine. The amount of work is too large, and it is impractical for Yizhou today. coming.

   Limestone mining, cement burning, and corvee collection are ready to end. It is already May, and at this time the winter wheat is also in the harvest season.

Because this batch of winter wheat used modern production technology throughout the whole process, the yield of winter wheat per mu reached about seven stones, which is 814 catties per mu. crops are more confident.

After harvesting 20,000 mu of land, Li Yin directly became a large grain householder. With 140,000 shi of grain, he had to temporarily build more than a dozen grain depots, which almost made his mouth crooked. These new grain warehouses are all built with sintered bricks and cement, and the floors are all covered with concrete. Li Min also specially bought waterproof materials to prevent rain from leaking and damage the grain in the future.

   After harvesting the winter wheat, Li Min planted hybrid rice, and in the autumn there will be a grain harvest of more than a hundred thousand shi. In addition to agriculture, the research institute has also made a lot of progress.

With limestone and a steelmaking furnace, the first batch of high-quality molten steel was produced in mid-March. Afterwards, Li Yin began large-scale production of steel to make agricultural tools. Li Yin still decided to put agricultural production on the The first one is that when the people have money, their consumption can keep up. In this era, wars are fought with money and food, and without money and food, nothing can be done.

  The production of this batch of high-quality steel agricultural tools was welcomed by the common people, and set off a buying frenzy in Yizhou for a while, and even attracted many businessmen to buy and sell them in other prefectures and counties.

Steel and cement have been solved. Two of the four projects formulated by Li Yin have been 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 Yin to imitate steam engines. Only steel is not enough to make this thing, rubber has to be used, and rubber is something that Li Yin will not produce here for the time being. He wants to monopolize it, and he will not let other people produce steam engines except him.

The difficulty of flintlock guns lies in the production of seamless steel pipes, which is also the process that Li Yin intends to monopolize. For this reason, he asked the modern machinery factory to specially produce a batch of manual lathes that do not need electricity, in order to produce flintlock guns. Component.

After two months of busy work, Li Yin's immigration application finally came down. He asked Xia Yan to use his relationship in advance to purchase a batch of ancient firearms in country m in the name of purchasing collections. After the purchase was completed, Li Yin took a plane to fly to Country m, put these firearms into the ring, and went to the gun shop to buy a semi-automatic pistol with additional bullets, but although country m is free to buy guns, there are certain restrictions, except that you can only buy semi-automatic weapons. The number of bullets is also limited, so the number of bullets Li Yin bought was not many, but it was enough for Li Yin to use. After all, he was using it for self-defense, not for fighting. Maybe he didn’t need it at all. For the sake of safety and mentality, after finishing this matter, Li Yin took the plane back to China.

Li Yin made such a big commotion in Yizhou for a while, after all, it aroused the attention of all parties. There were constant discussions about him in the court, especially the wheat with an yield of seven stones per mu caused the whole court to explode, but this The news is absolutely true, because the news brought by the merchants traveling to and from Yizhou and Chang'an is the same. Besides wheat, the most discussed in Chang'an is of course the new farm tools and the road being paved in Yizhou. The road problem is easy to say, The officials were not interested in this, but those tough farm tools aroused the suspicion of many caring people. If Li Yin could produce such good farm tools, he could also produce better weapons. This is a big deal.

In the early morning, Li Shimin was a little tired listening to the courtiers' report. These days, his ears were full of the words Li Yin and Yizhou. Some of them praised Li Yin, and some criticized Li Yin for no reason. It's all rumors of suspicion.

"That's enough! You have accused Min'er of treason since he was in Chang'an, and now you have relegated him 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 did Min’er do in Yizhou not for the people, not for the Tang Dynasty?” Li Shimin stood up and said angrily.

"Your Majesty, calm down. The courtiers have no malice towards the Sixth Prince. They are just curious about how the Sixth Prince obtained these superb skills. Whether it is winter wheat, steel, or even papermaking, these skills were unheard of before the Tang Dynasty." Changsun Wuji said road.

Li Ke sneered and said: "Father, my son has also asked about this matter. Liu Lang's things all come from a distant country called Luo An, because Liu Lang once rescued a Luo Anguo businessman, so this Luo Anguo businessman Thanks to Liulang, I passed on some commodities and advanced skills to Liulang."

"What the third prince said is very true. Recently, there are also businessmen who claim to be Luo Anguo in Guangzhou. It is said that these businessmen are very mysterious, but many people have seen them before, and the goods they sell are also very strange." Cui Shao came out and said. .

Li Shimin pondered for a while. He also heard that there was a businessman from Luo Anguo in Guangzhou. To be honest, he was also very curious about the current situation in Yizhou, so he said: "Since all the ministers are so curious about Yizhou, then follow me. Go to Yizhou to see the real thing!"

   (Huaxia Kingdom, changed its name to Luo Anguo for the last time.)
