"You're finally here." Qin Yuzhen looked at her daughter Zhao Ruoshui with a smile. For the first time in more than 30 years, the Empress of the Great Song Dynasty is really thousands of miles away from her daughter, and she is really happy to see her daughter.

"Mother, the Tongji Canal is about to be blocked." Zhao Ruoshui complained, and at the same time tightly tugged on the old lady's arm.

"Haha." Qin Yuzhen laughed. I haven't seen my daughter coquettish for almost a year, Qin Yuzhen is very happy. The other half was because she was with her husband when she passed through the Tongji Canal. So she didn't realize what crowding was all about.

"Grandma, long life knows no bounds." Zhao Ruoshui's son and daughter lined up and said in unison.

"Good, let's hug." Qin Yuzhen hugged her grandson and granddaughter one by one, and she was even happier in her heart.

The family happily met and entered Zhao Jiaren's residence.

"Mother, this place is more spacious than the Korakuen Garden." Zhao Ruoshui praised while watching.

"It still doesn't smell like a water town, it's too dry." Qin Yuzhen sighed. She is half of Lin'an, and there are various lakes east of Suzhou at this time. Kaifeng is a plain, which is very different from the climate in the south.

"I don't think my mother's skin is dry at all. You see me walking by water, and my mouth is chapped. ”

"That's the climate in the Central Plains. It's also thanks to your father for using some distilled water for me to drink. Otherwise, my stomach will be uncomfortable every day. ”

The colt didn't dare to speak, and his heart was a little speechless. He is a half-degree student and knows what distilled water is all about. The chapters in high school biology and chemistry textbooks are devoted to water, which is divided into soft and hard water according to its calcium content. The water content in the south is lower than that in the north, and the bacteria in the whole environment are different. That's why it's not adapted.

As for the more terrible southern 'miasma', it is a perennial mud that breeds a large number of bacteria and mosquitoes, and once it spreads by heat, it is fatal to people. The textbook also specifically describes how to deal with the 'miasma', that is, before winter, dig a deep pit in a place where there is no miasma, or find a large depression, and take advantage of the low temperature in winter, wear protective clothing to dig up the soil that breeds miasma, pour it into the god pit, and fill it with a thick layer of normal soil. Landfills also need to be marked, and the good soil over there will be planted with more antibacterial trees to allow the bacteria to die naturally after more than ten years.

As for the most problematic water, distilled water, but each liter of water requires a lot of fuel and is expensive. His mother-in-law drinks distilled water, although it is not a poor luxury, but it is also very particular. His old father-in-law is worthy of being a scientist, and as the legend goes, he takes great care of the queen. Seeing that the most noble couple of the Great Song Dynasty was so affectionate, the concubine originally thought that he would be envious. Thinking about the strength of his princess wife, there is a reason why the colt feels that he is not considerate enough.

When the queen and the princess spoke in private, the colt simply took the babies to the artificial lake for a stroll. After all, it is a lake in the Central Plains, and it is also a bit attractive to Jiangnan people.

Without these outsiders, Zhao Ruoshui was tired of being by the old lady's side, and said in a casual tone: "Mother, I'm annoyed to death now." ”

"You mean your land." Qin Yuzhen's face changed from a loving mother to a strict mother in a short period of time.

The mother and daughter will be very frank in many cases, and Zhao Ruoshui is more afraid of the old lady than the father, so she is also mentally prepared. She continued: "Mother, you have been with my father for so long, and I don't think you have gained anything. ”

"I didn't get anything, where would I have three of you brothers and sisters." Qin Yuzhen replied calmly.

"Mother, you always look at my father. You are such a delicate person, my father is good to you. But you're so afraid of my dad, I always feel wrong. Zhao Ruoshui said what was in his heart.

Qin Yuzhen's expression was calm, and her tone became spicy, "Your father is right, why don't I listen?" I have to be captured by the Mongols to regret it! ”

"My dad said that women have to rely on themselves, and I listened. But when I got to the joint, my father didn't help me. ”

"On your own, you're going to have to do it on your own. I think it's right that land is owned by the state. What's the use of you occupying so much land? ”

"Aren't you raising children?"

"You teach your children so that they can support themselves on their own. That's your responsibility......"

"Why do you have to make them suffer and suffer? I can't stand it! Faced with the old lady's opposition, Zhao Ruoshui was also anxious.

"Only when you suffer hardship can you become a superior person. You look at your dad...... Forget it, your eldest brother has watched how your father has come to this point step by step. You haven't seen how hard your dad is. Do you think the world is really that simple? Auntie, let me tell you, don't think about those things, the money you earn in the prescribed thirty years is enough for your children to eat for several lifetimes. ”

"What about thirty years from now? If there is a bad son in the family, the family business will fail! ”

"If something is wrong...... Qin Yuzhen suddenly wanted to pick up the unscrupulous girl Zhao Ruoshui and whip her hard. At this time, I remembered the bad boy! Isn't it the responsibility of my father and mother to have something wrong? It's just that I'm such a daughter, and I can't bear to beat her like this.

Qin Yuzhen sighed, got up and left. As he walked, he thought of his eldest son Zhao Qian. Among the three children, Zhao Qian was beaten the most, Qin Yuzhen was still young at that time, and she was really strict with Zhao Qian. In addition, Zhao Jiaren was not the emperor at that time, and his family was not bound by any imperial system at all. When Qin Yuzhen is older, she sometimes regrets it, and the resentment that she has a lot of time is actually not that Zhao Qian really did anything wrong, but that Qin Yuzhen has a big temper and can't help but have a seizure.

However, looking at it now, Zhao Qian is the most successful of the three children. If Qin Yuzhen does something right, it is to stick to the bottom line that everything has to rely on her own struggle. At that time, Qin Yuzhen's father was a jinshi, her father-in-law was a jinshi, and her husband was a jinshi. If you want to be admitted to the Jinshi, especially in a poor and remote place like Fujian, where there is only one way to take the Jinshi, it is natural to work hard. Not trying is an unforgivable sin.

Thinking of this, Qin Yuzhen stopped, and Zhao Ruoshui also chased after her. Qin Yuzhen turned her face, "Auntie, I heard that your father asked people to set up a new school, and you let your children come to this school." ”

"What school?" Zhao Ruoshui didn't dare to make a mistake, and asked honestly.

"It's better than your big brother's school." After Qin Yuzhen finished speaking, she turned around and continued walking. She really didn't want to see her daughter, for fear that she would not be able to help but pick up a broom and beat her.

Looking at the back of the old lady, Zhao Ruoshui knew that he had messed up. If you don't get the support of the old lady, you don't have to talk about anything else. Even if Dad is supportive, if the old lady doesn't agree, he won't agree to anything.

Zhao Jiaren didn't know that his daughter was calculating himself, and he was walking on the street with the Minister of Telecommunications. The two were dressed in ordinary clothes and were inconspicuous in the crowd. When I stood opposite the entrance of the telegraph office, I saw a long queue at the entrance of the telegraph office. It's all the people who go to send telegrams.

The minister sighed: "Official, you used to say that telegrams can make a lot of money, but I don't believe it. At this time, I have to believe it. ”

As he spoke, the staff member who received the letter opened the mailbox at the entrance of the post office, which was next to the telegraph office, and the letters poured into the green canvas bag. Not only are there many telegrams, but now the postal system of the Great Song Dynasty is also facing more and more workload.

"That's a good thing." Zhao Jiaren said with a smile. He did write letters from an early age, but by the time he was older, the fixed telegraph was widespread, and no one among the young people was happy to write letters. Later, mobile phones and the Internet became popular, and writing letters was a wonderful thing. In the 21st century, the Chinese telegraph office has closed its doors. Now seeing the rise of the telegraph office, Zhao Jiaren felt an inexplicable joy.

"A five-fold increase in manpower, and a fourfold increase in communications at this stage. What do the officials think? The Minister of Telecommunications asked.

"That's pretty much it." Zhao Jiaren nodded.

"When the new automated reporting device becomes widespread, it will be easy. With the addition of automatic transmitters and five radio waves, this amount of communication can be increased by more than ten times that of the previous one. "The minister seems to be weak in mind when he describes the future.

Zhao Jiaren did not blame the minister for being conservative, he predicted that the telegraph system, which cost the country countless money, would become the country's most money-making department, so he gave the telecommunications and postal services to the independent city ministry. At that time, it was also suspected by many people. Borrowing the east wind of the northward migration, this prophecy soon became a reality. If the people have money in their hands, the communication industry will naturally have users. It's like the 21st century, you have to get in touch before eating. I have to contact a lot of people. So Zhao Jiaren smiled and said, "You can go and prepare." ”

After talking with the Ministry of Telecommunications, Zhao Jiaren went to the Ministry of Agriculture. As a result, the Ministry of Agriculture immediately issued a locust warning. The groundwater level in the Xiaoice weather era is still relatively high, but the surface water is insufficient. Groundwater was pumped with steam engines, and even prototypes of the initial internal combustion engine for burning gas. The Ministry of Agriculture is only worried about the lack of money, but it is not worried about agriculture.

This time, the Minister of Agriculture nervously said to Zhao Jiaren: "Official, there are signs of danger in the locust plague in the north and south now. ”

"Hmm." Zhao Jiaren first remembered Zhao Qian's unreliable plan, locust plague prevention depends on the people, that is, Tubaozi can come up with it.

Pointing to the area around the old route of the Yellow River, as well as several areas with very serious soil and water damage from the south of the Yangtze River to the Huai River, the Minister of Agriculture was also very anxious. "Official, greening in these areas is a big problem."

Humans purposefully eradicated a living organism, presumably the smallpox virus. In the 21st century, it is said that in addition to the wilderness of the permafrost zone in Siberia, there may still be a little smallpox virus that exists without flare-ups. With human vaccination, the smallpox virus is definitively only present in laboratories in two or three large countries. The reason why the samples were not completely eliminated is that smallpox, as a virus, has some research value.

But humanity had no plans to exterminate all locusts on the planet by that time. Even in many regions, such as Israel and other parts of the Middle East, locust plagues have always existed.

From an environmental point of view, it is mainly caused by drought. The main reason for this phenomenon is that the arid environment has many benefits for locust reproduction, growth and survival. Because locusts lay their eggs in the soil. The soil is relatively solid, and the water content is 10%~20% when it is most suitable for them to lay eggs.

Drought causes locusts to multiply and grow rapidly, causing disasters in two ways. On the one hand, in drought years, due to the drop in water level, the soil becomes more solid, the water content is reduced, and the ground vegetation is sparse, the number of eggs laid by locusts increases greatly, and it can reach 4000~5000 egg masses per square meter of soil, and there are 50~80 eggs in each egg mass, that is, 200,000~400,000 eggs per square meter.

In dry years, rivers and lakes shrink and low-lying areas are exposed, providing more suitable places for locusts to lay eggs. On the other hand, plants grown in arid environments have a lower water content, and locusts feed on them, growing faster and having higher fertility. At the same time, drought has caused explosive migration, from arid areas to low-lying and flood-prone areas.

Zhao Jiaren knew that this was the biological knowledge that Zhao Jiaren recalled and passed on to the agricultural department. Therefore, several areas that the Minister of Agriculture is concerned about are semi-desertified areas due to Xiaoice weather.

Most of these areas are saline-alkali land, and it is difficult for plants and trees to grow. It gave the locusts a chance to multiply. The Great Song Dynasty already had a relatively special unit aimed at the locust plague, and they hired the masses to dig up locust eggs during the slack season, and dealt with them in various ways.

But there are limits to this effort. After all, it is very difficult to move on wasteland that can easily cover hundreds or thousands of square kilometers. It's not like driving a van in a movie, and more than a dozen people come out of it. Or the third brother's military exercise 'circus', a dozen people on a motorcycle, from the driver, the shooters on both wings, the stabilizers above, the kryptonite dog-eye observers in front and other teams.

To exercise hundreds of people in the wilderness, you have to have a considerable amount of logistics. Anyway, Zhao Jiaren was very familiar with this, and he had to think carefully about it when he made war plans. Without food and drinking water, the army marches long distances and kills.

"How likely do you think?" Zhao Jiaren asked.

"Thirty percent." The Minister of Agriculture replied uneasily. He didn't know whether to say more or less, it was not appropriate anyway.

"Then be careful. It can only be so. And it's no wonder you. Zhao Jiaren sighed.

"This greenery is very difficult. There are also villages in those areas, and when they are green, they go and cut down trees. No matter how much you persuade, it's useless. I think it's a catch? The Minister of Agriculture sighed.

"Let's migrate." Zhao Jiaren ordered. He knows how difficult it is to work at the grassroots level, and his home is in Anhui, which is where the people of the poor countryside come out. There are even any
