The guards sent out by Li Erye rushed back in waves, bringing back good news. Effective! None of the pox people are infected with measles! The side effects are not obvious, just a small blister, and the punishment they receive is like being bitten by a mosquito.

Li Erye was overjoyed, and the number of laughs increased significantly. However, after more than ten years of war and plague, the population dropped sharply from more than 8.9 million households (more than 46 million people) in the previous dynasty to 1.8 million households (9 million people) in the first year of Wude. Li Yuan's father and son will definitely not carry this pot, just throw it to the previous dynasty, the reason is that Yang Ying and his father do not cherish the people, and the projects that cost the people and money have not been done, causing the people to have a poor livelihood and wolf smoke everywhere. He is the savior, and he has managed to hold the lives of more than 9 million people......

Many people have done this, scolding the front, while enjoying all kinds of tangible and intangible property and conveniences left over from the front, without any psychological burden......

The so-called prosperous era in history is actually very simple, there are many people, and they can eat enough. On this basis, it is enough to win a few more battles, bulldoze a few small disobedient countries, and gather a few more foreign nations to come to worship.

For Li Erye, now the people who died of hunger have been basically eliminated, and there is more land than the previous dynasty, but the people are only one-fifth of the previous dynasty! After the implementation of the uniform field system, as long as you are willing to work hard, even if God does not appreciate your face, you will not easily starve to death.

Another issue that made Second Master Li choke in his throat was population. The infant mortality rate is too high! There are mothers who are too young and congenitally deficient, and there are those who have not survived the disease, both of which account for a lot.

Measles, this disease is not picky, it covers a wide area, and the fatality rate is high. Pox is not expensive, the people can afford it, if everyone in the Tang Dynasty is vaccinated with pox, how much can the mortality rate be reduced? Even 1% is impressive!

"Returning to Tang is really my lucky star!" Second Master Li hugged the little princess of Chengyang, and while provoking her with his hands, he said to the eldest grandson queen: "I remember the iron he made first, right?" Later, it was papermaking, printing, cotton, and jade potato. ”

"There is still some food, and there is no shortage of tables and stools, even medicine." Empress Eldest Sun watched the two of them playing, and she was also very happy, "A while ago, Gui Tang made another soap, and Lizhi brought back a lot, and the concubine is easy to use." ”

"It's true that you say that, but except for the medicine, it's all a small way, and Gui Tang, this kid is too lazy and too greedy for enjoyment." Hearing what Empress Changsun said, Second Master Li was happy, "Look at these things, which one is not for comfort and satisfying the desire of the tongue?" ”

"Maybe. But listening to Lizhi, Jinjiazhuang has changed a lot. The dealers are all beaming and very energetic. There's even a bazaar. Empress Changsun picked up the pu fan and fanned the two of them for some cool breeze, "The girls in the nearby Zhuangzi all want to marry in Jinjiazhuang, and the girls in Zhuangzi don't want to marry outside. ”

"Hahaha. There is still a hand in returning to Tang to make a fortune. "Jinjiazhuang, Second Master Li feels that he hasn't been there for a long time, if the villages of Datang can have half the level of Jinjiazhuang, then the prosperity he expects has been reached.

"That's it, the front foot just made a lot of money from King Lu Zheng's family, and the back foot made a lot of money from the hands of the Japanese envoys." Empress Changsun agrees with her husband's point of view, with Changle here, Jinjiazhuang is like transparency in front of her.

"I know that." Speaking of this stubble, Second Master Li was even happier, "Gui Tang, this kid is too bad!" A while ago, he asked Changle to hand over the recital. That's a bad word, hahahaha! ”

"What he learned is different, Gui Tang didn't learn calligraphy since he was a child, and his hard pen writing is still very good." Empress Eldest Sun said a fair word for Jin Yu, "But why is he broken?" ”

"That's the point. He said in the recital that this potato has begun to degenerate, and he is thinking about what kind of detoxification project he wants to do. If you don't detoxify, if you plant for another three or five years, you will not harvest grain, but poison! Second Master Li also has his own doubts, "It's strange to say, Gui Tang is very wary of foreign countries, he just finished pit Goguryeo a while ago, and now he is putting the Wa Kingdom to death." ”

"Isn't that bad? It shows that he is on the side of Datang. "The eldest grandson queen is virtuous and virtuous, not uninformed. Is there really friendship between countries? Which time was it not typed? Weakening other countries and strengthening oneself is the way to survive!

"Okay, who said badly." Second Master Li put his doubts behind him, "A while ago, this kid made another method of planting pox, and I sent someone to verify it, and the effect of preventing measles is good." In a few days, I will have the Imperial Physician come and plant it for you. ”

"Huh?" Empress Eldest Sun was a little crying and laughing, "Didn't he say that he had already emptied the prescription he knew?" Why did another one pop up? ”

"When I had a toothache two years ago, the one provided by Gui Tang was called toothpaste, right? I see that Gui Tang is a toothpaste, and I can't squeeze it out, so I plan to squeeze him well. Li Erye searched his intestines and scraped his stomach, and finally found a suitable description.

"Your Majesty is planning to reuse him?" Empress Eldest Sun is very strange, and she said before that she would leave it for Cheng Qian, and the change is a bit fast.

"You can't let him be so idle, what is the future of planting grass or something? A few days ago, Cheng Qian asked Tang Guitang to summarize the methods of farming and growing vegetables, and wanted to promote it. Li Jing's statement made Li Erye a little unexpected, after all, he usually behaved in the court and didn't speak easily.

"This is quite unusual, it is not easy to make Dai Guo speak publicly." Empress Eldest Sun was also surprised when she heard this, "I guess it's the Duke of the Country, right?" ”

"That's just one aspect." Li Er pondered, "I may also have the reason for Hou Junji's last gathering. Either way, it's a good thing. ”

"Then which yamen does Your Majesty plan to send him to practice?"

"I haven't thought about it, what he learned doesn't match any yamen." Second Master Li had a slight headache, "Let's discuss it later, I want to promote the pox first, and the recipe hasn't been taken from Gui Tang yet." Planting a pox costs two or three cents, and spending a small amount of money can prevent measles, which can buy people's hearts very much, and it is not appropriate for Tang to do it. ”

"This is a great thing that can be seen and touched, and it is good to be able to benefit the world." Empress Eldest Sun frowned slightly, "But it's not appropriate to come over directly, right?" Even if two or three cultures have a pox, Datang has nearly 10 million people, this is not a small income, there are newborns every year, if it is promoted, this is a long-lasting business. ”

"yes." Second Master Li also sighed, "I sometimes envy Cheng Biting Jin, this matter is not a problem for him, he can directly grab the door!" The skin is thicker than the city walls, but I can't do it! ”
