After deciding on a new sales strategy for the specialty store, Li Yin and Cui Yingying discussed and decided to publish the recruitment of agents by the Shengtang Chamber of Commerce in the Shengtang Commercial Daily, and attract investment from the Tang Dynasty. After more than half a year, the Shengtang Commercial Daily The influence in Datang is increasing day by day. As long as they can read and write, those who have money will buy every issue, and those who have no money will gather together and buy the next copy. Newspapers learn about the latest policies of the imperial court, and sometimes, Li Shimin even asked eunuchs to record the content of the court meeting, and then published the content in the commercial newspaper the next day. What a temptation for literati and businessmen. Power is tantamount to indirectly participating in the government.

For merchants, the importance of this newspaper is even more self-evident. All kinds of product information and advertisements can be found on it. He became a popular figure in Chang'an, and countless merchants fawned on him, hoping to get priority in getting the right to advertise in Shengtang Commercial Daily.

The Shengtang Business Daily has now set up branches in the wealthy states of the 15th Tang Dynasty, so the transmission of information between branches has become a big problem. The method was changed to carrier pigeon delivery, which made the efficiency much higher. Now when Li Yin sends information to Chang'an Shengtang Business Daily, he uses carrier pigeons from the newspaper.

The rest was handed over to Cui Yingying, and Li Min began to get busy with the spring plowing and the equipment of the research institute. He inquired about the crops that could be planted in March, thought about it and decided to plant potatoes, sugar cane, peanuts and purple sweet potatoes, while cotton had to wait until It can only be planted in May, which is also the season for winter wheat harvest.

Li Yin has his own considerations in choosing these plantings. Needless to say, potatoes and purple sweet potatoes are high-yield crops with a yield of tens of thousands of catties per mu, and they are a sharp weapon to save famine. Sugarcane is the raw material for white sugar, and vegetable oil production is of course Peanuts are the best, not to mention cotton, you can count on it for cotton cloth.

Of course, in addition to the crops that Li Yin brought from the 21st century, Yizhou also has original ecological local agricultural cultivation, such as tea and mulberry, which are world-famous in Yizhou. For this year's tea, Li Yin decided to introduce The technique of frying tea changed the weird tea-drinking atmosphere of the Tang Dynasty. As for mulberry, Li Yin encouraged it. Shu brocade is still a high-end consumer product of the Tang Dynasty.

Back at the villa on the isolated island, Li Yin called Xia Yan. Li Yin now has his own grain and vegetable base, and he doesn’t need to bother to buy these things. He made a phone call and told her the number of seedlings and seeds Just let her prepare it. The same is true for steam engines and small blast furnaces. The steel plant and machinery plant under him are all ready-made, so there is no reason not to use them.

In addition to asking Xia Yan to do these things, Li Yin went to the hardware store to search again, bought a few sets of tools that could be bought, and prepared to move them back to the research institute. He even bought some equipment for chemical and physical experiments. Things are used sooner or later.

After being busy for a few days, Li Yin transported the tools he bought back to the research institute. As soon as he entered the door, he heard a "boom", and then there was a burst of cheers from the test field to the west. Li Yin listened carefully. Listen, isn't that the testing ground for the flintlock research team?

   Just as he was thinking about it, many people rushed out from the room of the research institute to surround him, and Tong Yu also came out. When he saw Li Yin, he immediately came over and saluted.

  Li Yan said with joy on his face, "Go, go over and have a look, maybe the black flame research has been successful."

   Tong Yu answered yes, and followed Li Yin to the testing ground. At this time, many people had surrounded the testing ground, and such a big commotion attracted many craftsmen.

   Seeing Li Yin approaching, all the craftsmen dispersed. A man dressed as a Taoist priest was squatting on the ground to check the broken bamboo pieces, smiling all over his face, as if he was satisfied with the degree of explosion.

   "Guo Xianyuan, has the research on gunpowder been successful?" Li Yin walked over and asked.

Guo Xianyuan stood up and said, "Your Highness, it has been developed according to the materials and ratio you mentioned." As he spoke, he took out another bamboo knot, which was the thing that exploded just now. A hole was drilled in the middle of the firecracker, and then flames were poured into it and ignited, which caused a violent explosion just now, "There is another one, please take a look, Your Highness!"

This Guo Xianyuan is an alchemist in a local Taoist temple in Yizhou. When Li Min was recruiting strange people in Yizhou, he took the initiative to ask Tong Yu to sign up. According to him, the current mountain fire made Yuan Tiangang and him the same Those who came out of a Taoist temple only specialized in surgery. Yuan Tiangang was proficient in physiognomy, and he was proficient in alchemy. When he saw Li Yin, he even took out a few dark "golden pills" for Li Yin to taste.

  Tang Dynasty believed in Taoism, and many people were obsessed with Taoism. Even Li Shimin, a hero, was no exception. In his later years, his health went from bad to worse, and it was because of taking these pills that he finally died.

Li Yin naturally understands what Guo Xianyuan's idea is, it's nothing more than wanting to be a retainer of the palace, but Li Yin is not a fool, to eat the elixir rich in harmful elements, he will immediately pull this guy out The urge to chop.

Li Yin was indifferent to the elixir, this Guo Xianyuan changed his tricks again, saying that he was performing a spell for Li Yin to see, and then this Guo Xianyuan took out a ball of black powder and put it on the ground, holding a piece of paper in his hand. The yellow paper chanted the spell for a long time, then lit the yellow paper and threw it on the powder, a flame burst into flames, startled Li Yin's guards at that time, and rushed to protect Li Yin.

   Others don't know what it is, how can Li Yin not know? Guo Xianyuan, who played this little trick with him, was directly thrown into the research institute by Li Yin, who gave him a ratio and ordered him to create a powerful gun within a month, otherwise he would be pulled out and beheaded, and he would be scared immediately. Got to collapse on the ground.

Li Yin took Guo Xianyuan's firecrackers and looked at them. In fact, they were just bigger firecrackers. Li Yin poured the gunpowder into his hands and said, "The powder is too rough. Grind it finer. The ability to burn is more fully."

   "Yes, Your Highness!" Guo Xianyuan said.

  Then Li Yin looked at the craftsmen and said: "You are all watching the fun, go and carry your tools!"

   "Tools?" Tong Yu recalled the truckloads of things brought in just now, "Your Highness, the small blast furnace has also been brought in?"

  Li Yin said: "That's right, it saves you from being confused, and you can always make it if you have a real object for comparison!"

"Your Highness, don't worry!" Come on, Tong Yu led the people trotting all the way to the door, Li Yin also followed, and he had to hand over the usage of these things to them one by one, so as not to cause any accidents .
