Fifteen years have passed.

It has been fifteen years since the Battle of Jingjing, and the fifty-five-year-old Zhu Di has become an existence comparable to the first emperor in China.

The territory of the Ming Dynasty can reach the south coast of the Arctic Ocean directly from the north, the Bering Strait from the east, the Minwei Island in the south, and the former land of the Golden Horde in the west to the Caspian Sea.

Daming's ships traveled around the world along the proven routes, transporting gold, silver, minerals and other minerals back to Daming in a steady stream.

The population of Daming has grown dramatically in recent years, reaching more than 80 million people.

Under the Tanglu Mountains, built a palace, every summer and autumn, the emperor will stay here, after the hot summer, when the weather turns cool, then take the train back to Beijing, when the first snow falls, take a boat from Zhigu to Yamato Prefecture, spend a winter there.

In the words of the emperor, soaking in hot springs on a snowy day is simply the greatest enjoyment.

Under the Tanglu Mountains, a large town has been formed on the shore of Ubusu Lake, around the emperor's palace, dignitaries, ordinary people, have built houses here, not to the summer and autumn season, the flow of people here is like a tide, gathering people from all over the world to trade here and create value.

Sandwiched between the Tanglu Mountains to the north and the Altai Mountains to the west, the Zabkhan River flows from north to south, like a jade belt, on the southern shore of Lake Ubusu.

Zhu Di's horse team returned to the city of Ubusu along the Zabhan River, and when he entered the city gate, the first snowflakes seemed to fall from the sky, and he gave the order to return to Beijing.

The next day, the train carried Zhu Di and his accompanying ministers over the mountains and mountains, and arrived in Beijing on the morning of the third day.

Zhu Gaoxian led the eldest son, eldest daughter and second son to pick up on the platform, and the three children saw Zhu Di get off the train, flew over like a milk swallow, and rushed into Zhu Di's arms, "Imperial Grandpa" kept shouting.

"Hahaha, I want to kill you!" Zhu Di picked up Zhu Gaoxian's second son, touched the heads of the finch slave and the big girl respectively, and asked in a voice full of love, "Have you studied hard?" ”

Zhu Gaoxian came over, greeted Zhu Di, and said with a smile, "Dad, let's get in the car and talk!" ”

In the car, Zhu Gaoxian asked about the hunting trip, "My son is still talking, why is it this time, my father hasn't said that he wants to come back, and he is going to call to ask." ”

"Every year I go hunting, I finally come back with a little strength in my arms, and when I go the next year, I have to start practicing again, and my father comes back a few days later this year and wants to train his strength."

Zhu Di is holding Zhu Gaoxian's second son in his arms, who is only three years old this year, his nickname is Tannu, and he was born with a lovely ball of jade snow.

He turned around, hugged Zhu Di's neck, kissed him fiercely on the face, and slapped Zhu Di's face, causing Zhu Di to laugh and show off, "Tan Nu hasn't seen the imperial grandfather for so long, and he still likes the imperial grandfather the most!" ”

Xu was in the latter car, accompanied by the finch slave and the big girl, and told the two children some interesting things about the city of Ubudsu, "There are more and more people who go there to spend the hot summer this year, and there are two percent more than in previous years, and the people are getting richer and richer day by day!" ”

The bird slave is eight years old this year, the eldest girl is one year younger than him, and both of them have officially gone to school, so they can't be the same as when they were children, and they live in Ubusu Lake with the imperial grandfather and the imperial grandmother for a summer.

The big girl said, "Grandma Huang, Daddy said that this winter, my granddaughter will accompany Grandma Huang to go to Yamato Prefecture to soak in hot springs, and Da Niu will serve Grandma Huang." ”

Bird slave looked dark, he couldn't go, his father said, he has grown up, and his future thoughts will be used to study, in addition to reading in school every day, he has to follow his father in the laboratory every night to do experiments, when his father goes to Jiuquan, he also has to follow, compared with his peers, he has mastered more science and technology, and the truth of how to behave in the world.

The next day, Zhang Ben returned to the court, compared to more than ten years ago, when he was appointed as the governor of Annam and Zhancheng for the first time, Zhang Ben did not seem to be old, but it was very dark, and his eyes were full of light.

Seeing Zhang Ben, the civil and military forces of the Manchu Dynasty were very shocked, and they all looked at him with eager eyes, not knowing what kind of good news he would bring to Daming.

"Congratulations to the emperor, congratulations to the emperor, the new generation of hybrid rice developed in the hybrid rice laboratory has been trial-planted in the Jianghan Plain this year, and the yield per mu has reached more than 600 catties."

As soon as these words came out, the Manchu Dynasty sounded an exclamation, and everyone's mouths opened wide, only to feel that all this was unbelievable.

The yield per mu has increased from more than 300 catties to more than 600 catties, what kind of speed is this.

There is a speed called Daming speed.

Zhu Di stood up from the dragon chair, he went down the stairs directly, walked to Zhang Ben, and asked again, "How much do you say?" More than 600 catties, doubled? ”

"Yes!" Zhang Ben was very excited, and tears flashed in his eyes, "Although the yield per mu has doubled, it is still far from the height set by His Highness!" ”

"What is the height of the fourth child? How much is the yield per mu? Zhu Di asked.

Zhu Gaoxian smiled but did not answer, Zhang Bendao, "If you go back to the emperor, Your Highness requires a yield of at least 1,500 catties per mu." In the past, the minister did not have much confidence, but this time, the minister found a way, and the minister was confident that he would reach this height set by His Highness in his lifetime. ”

Zhu Di slapped Zhang Ben's shoulder heavily, "Zhang Ben, Huang Fu!" ”

"The minister is here!"

Huang Fu also followed, and the two knelt in front of Zhu Di, only to hear Zhu Di say in an irrepressibly excited voice, "The two of you, one has made a lifelong contribution to my Daming's rubber cause, and the other has made outstanding contributions to my Daming's hybrid rice research, you are all qualified to occupy a place in my Daming Academy of Sciences, which is an honor given to you in the field of science." ”

Hearing this, everyone probably knew that the emperor was going to reward them, and all the civil officials looked at these two people with envious eyes.

"The Ministry of Rites intends that Zhang Ben and Huang Fu have meritorious service, and the imperial court will reward them for their meritorious deeds, and confer the title of Viscount Zhang Ben and Baron Huang Fu."

The Ming Dynasty was ranked fifth, in order to seal the relatives of meritorious officials, and later, leather and male, only retained the prince, marquis, and uncle. In the seventh year of Yongle, in order to commend the heroes in the field of science and technology, Zhu Di ordered that the titles of viscount and barons be retained and awarded academicians of the Academy of Sciences, and these heroes will have titles and food.

Leaping into the aristocracy, Zhang Ben and Huang Fu were moved to tears, kowtowing to thanks, and shouting long live.

But no one can be jealous, and the credit made by the two is real. Needless to say, Zhang Ben doubled the yield per mu, which means that the land owned by the Ming Dynasty will double the annual grain output from now on, and there will be no hunger in the prosperous era.

The status of rubber in the industrial field, but anyone with a little common sense can see that rubber, as His Royal Highness said before, is one of the four major resources of industrial development, occupying an indispensable position.

If there is no large-scale rubber planting in southwest countries, the industrial development of Daming may not be so rapid.

After the next dynasty, the civil and military officials all rushed to Zhang Ben and Huang Fu's house, celebrating the two Ming upstarts, the Zhang family and the Huang family got the news one step earlier, and the house began to be cleaned up, intending to welcome the guests who came to celebrate.

Zhu Di is enjoying family fun in Xu's palace, Zhu Zhanji happened to be in the capital in the past two days, and he came to greet the emperor's grandfather, Zhu Di asked how the flight project he was doing was progressing?

"Tests have already been done in the wind tunnel, and if the tests are successful, they can make their first flight." Zhu Zhanji was obviously excited, he said, dancing with his hands, and accidentally said the wrong thing, "My grandson plans to go back to the northwest yesterday, but the fourth uncle insists that my grandson stay, saying that the emperor's grandfather and grandmother are coming back......"

"Ahem!" Zhu Gaoxian coughed lightly twice, and glared at Zhu Zhanji fiercely, "Why haven't you seen you for a few days, and you're getting more and more stupid?" Where did all that cleverness go from before? Will you be able to speak? ”

Zhu Zhanji stuck out his tongue with a smile, he was dressed in a military uniform, and he was dressed very sloppily, his hair seemed to be uncombed for a few days, and said with a smile, "I also learned from the fourth uncle, my teacher said that when the fourth uncle led them to overcome the project, it was such a race against time, and he also said that it was a race against time!" ”

Zhu Di naturally didn't mind at all, but laughed out loud, "Since you have already asked me and your imperial grandmother to say goodbye, then you should take the fastest train to the west as soon as possible." I'm waiting to hear good news from you, I want to take a plane! ”

"Grandpa Huang, my grandson promises that within three years, I will be able to let you get on the plane, and in the future, you will not have to take a boat to Yamato Prefecture for a vacation."

"Okay, I want to go to Mingwei Island to have a look, your fourth uncle said, it's too far to take a boat, it's poor over there, and the conditions are not good, I still want to go and see."

"This matter is wrapped up in my grandson!" Zhu Zhanji patted his chest, and as he spoke, he retreated towards the palace gate, then saluted, turned around, and ran away with a smoke.

Zhu Di was very relieved, and whispered to Zhu Gaoxian, "Dad used to be very worried about your eldest nephew, but now, seeing him obsessed with science, Dad is finally relieved." ”

Zhu Gaoxian said, "Science is a mysterious field for human beings, once you enter this field, the desire to explore is involuntary, no matter how much you pay, it makes people feel very worthwhile, because you can always dig up treasures." ”

"How's that missile system you got going?" Zhu Di couldn't help but ask.

"When my father comes back from a vacation in Yamato Prefecture and goes to the west, I can see how the missile system is, and my son wants to describe it to my father, I can only say that there is some progress for the time being, and it is still far from perfecting this missile system, but now these equipment, any country that provokes my Ming Dynasty can only end up with no bones."

Zhu Di didn't know anything about this, he only understood a little, the strength of Daming's weapons and equipment was far from being comparable to that of any country, and that was enough, and he didn't bother to worry about it.
