Zhu Gaoxian said, "There are several large countries in the west, the Timurid Empire was established by the descendants of Genghis Khan, and the Ottoman Empire was a multi-ethnic empire established by the Turks. The Golden Horde was also one of the four major empires of the Mongols at that time, and it was an empire established by Batu, a descendant of the Golden Family. “

"Back then, after the death of Ogedei, his queen was a ruthless character, although Ogedai hated her eldest son Guiyou very much, but she still grabbed power and made Guiyou succeed in ascending the throne. Batu returned from the battlefield of Western Europe and did not want to wade into this troubled water, so he stayed in his fiefdom. In the early years, it was the territory of the Kipchaks, so it was called the Kipchak Khanate, and the Central Plains people used to call it the Golden Horde. ”

For this information, Zhu Di did not know very well, after all, there were no mobile phones and networks at that time, and the Ming Dynasty, who was in Asia, was separated by two large lands about what happened in distant Eastern Europe, and Zhu Di was fighting with the Northern Yuan for the first half of his life, rebelling for survival, so he naturally did not know.

Zhu Gaoxian gave his father a popular science based on a little historical knowledge he had learned in his spare time, "Badu is a majestic khan, but his descendants are not like this." Moreover, the Mongols were always fond of reducing their conquered peoples to inferior citizens, even offering the first night of their bride's life to the Tatar princes. Fortunately, these barbarians are real nouveau riche, and they do not have the humanistic accumulation of politics, culture, art and religion, and once the descendants of Batu fail, the Rus' backlash will be very strong. ”

Zhu Di heard the meaning of Zhu Gaoxian's words, "Ross? Those who are now ruled by the Golden Family? ”

Zhu Gaoxian racked his brains, "This matter is also a disaster caused by a small country called Khorezm, whether it was then or later, the Europeans called the Mongol invasion 'Yellow Peril'." ”

At that time, Genghis Khan had not yet conquered the Central Plains, and there was still the Jin Kingdom in the east. But this small Central Asian country felt that it had grown stronger after the annexation of Persia, and somehow killed all the caravans sent by the Great Khan to trade, totaling more than 400 people, and swallowed the goods. ”

Zhu Di only felt ridiculous and asked, "What happened later?" ”

The father and son walked and talked, and stood on the walls of Miyagi, looking at the north in the distance.

"Later, the Mongols destroyed the Western Liao, and the Western Liao was originally a barrier between Mongolia and Khorezm, but now the barrier is gone, and the Mongols' iron horses have poured down thousands of miles, and Khorezm has become a white land."

Later, the habit of "slaughtering the city" of the Mongol cavalry also began from this moment.

Zhu Di gasped, but he also felt that everything was unexpected, the emperor's wrath, millions of corpses, and thousands of miles of blood were not lies.

"How did you get involved with the Rus?" Zhu Di has no concept of these countries at all.

At that time, the king of Khorezm took advantage of the national turmoil and fled from the capital to a small island in the Caspian Sea. The two generals who led the expedition on the Mongolian side were Jebe and Subutai, and they chased after them, and they chased them to the Kipchak steppe. ”

The Kipchak steppe was the territory of Kievan Rus'.

At this time, the entire Eastern Slavs were divided into three tribes, the Russian people in the east, the Belarusian people in the northwest, and the Ukrainian people in the southwest.

The same nomadic people, one of whom was a polar bear in the north, as a result, as soon as the Mongols came, these Rus' princes were in a hurry, and in the first battle of the Chalka River, all the lands conquered by the Mongol legions were given to Genghis Khan's eldest son Jochi.

After Genghis Khan died and Ogedai ascended the throne, he launched the "eldest son's western expedition", and the commander who led this western expedition was Batu.

The Mongol expedition to the west lasted six years, and all the countries in the Rus' territory were subjugated by the Mongols, and the Mongol cavalry was the only army that was not dragged down by the Russian cold, and it took less than a week to capture the capital city of Vladimir.

And because of the arrival of spring, the Mongolian cavalry was not accustomed to walking on muddy roads, they turned around and went south, and the soldiers were divided into two routes, all the way to Poland and all the way to Hungary, even if there were more than 600,000 knights in Western Europe, they still could not stop the Mongol army, they were invincible, and fought all the way to the Danube.

If it weren't for the death of Ogedei, the whole of Europe would have to fall.

Zhu Gaoxian sighed, "The descendants of the Golden Family terminated the invincible expedition to this place in order to compete for Khan Wei, and the death of Ogedai gave the Western European countries a way to live. ”

"No empire can last forever, the Golden Horde occupies other people's land, after so many years, no one has one or two unscrupulous descendants, and the descendants of Genghis Khan are not all heroes, and there will always be times when they can't control the principality below. The son's idea is to send someone to find out the news, and in the future, when the imperial court has more control over the north and west, he can consider developing to the north. “

"There aren't many of us in Daming!" Zhu Di only felt that the blood all over his body was boiling, "Should we consider encouraging childbirth?" ”

Zhu Gaoxian said, "We should not give too high social welfare, but mainly consider the survival rate of young children, improve the treatment of women who give birth, strengthen the construction of the medical system, give birth to women who give birth to three years of maternity and breastfeeding leave, and give a subsidy of 50 to 100 wen per month, so that the population will grow." ”

Zhu Di said, "A supervision mechanism is needed. ”

Zhu Di said this, his hands clenched into fists, "The richer you are, the more you nourish corrupt officials." ”

"Dad, money and power should be managed separately, a bank should be established, that is, a money bank, and subsidies can be managed through the bank, and a strict approval system should be established to reduce corruption."

Zhu Gaoxian always felt that there was no way to eradicate corruption, which was a weakness of people's hearts and there was no way to overcome it.

Speaking of this, Zhu Gaoxian said, "Dad, the National University of Defense Technology can't just learn the knowledge of science and engineering, and my son thinks that someone should be arranged to teach some knowledge of the art of war and strategy." Why don't you take the time to talk about two examples in history and analyze them for students? ”

"You mean, let Daddy go?" Zhu Di pointed at himself in disbelief, "Is this appropriate?" ”

"What's out of the ordinary? Dad, every class of students of the National University of Defense Technology must be a protégé of the Son of Heaven, and my son plans to set up a project team in the name of the Ministry of War to develop missiles and establish a defense system of our Ming Dynasty, so that in the future, he can point to that and hit there, and can lock on to any target on land, in the air, and in the sea. ”

"And these people, Dad, the son hopes that Dad can award all the people in the project team to military ranks." Zhu Gaoxian thought of the practice of later generations, "I am afraid that an independent place will be opened up to conduct these studies, and some core personnel, whose names will not be known throughout their lives, will be well arranged by the imperial court." ”

Zhu Di said, "What is a missile? ”

Zhu Gaoxian actually doesn't know much about himself, he plans to rely entirely on the system, and if it can really be developed, I'm afraid it will take many years, said, "According to the range, it is divided into medium-range, long-range and intercontinental missiles, and the range of medium-range missiles is about 3,000 kilometers, and there are three as far as Yingtianfu to Shuntianfu, and the meaning of intercontinental missiles, to put it bluntly, is that missiles can be launched from Asia to the Americas." ”

Long-range is between medium-range and intercontinental.

Zhu Di and Zhu Gaoxian look at the world map all the year round, and know which plate Asia refers to, where is the Americas, if the earth is an elliptical planet, then this missile has to turn a corner to hit the target, how did it do it?

He didn't expect that the weapons of later generations would have advanced to such an extent.

"In later generations, there were five nuclear powers, one of which was our neighbor to the north, the current Duchy of Rus', and then the two countries in Western Europe, our Chinese nation, and the last one was the descendants of the British who occupied the territory of the Indians in North America, and they established a beautiful country. An atomic bomb can destroy a city of Beijing, and make this land not grow a single normal grass for a hundred years, and even a mouse can be extinct or mutate into a dog. ”

"Why?" Zhu Di was so shocked that he couldn't close his mouth for a long time, what kind of weapon is that, it can still mutate creatures and not grow a single grass?

"Some people say that it is a magic box, once opened, all that comes out is the devil, but who in this world can avoid the application of nuclear materials?"

Zhu Gaoxian said, "If we build an aircraft carrier, it is a behemoth at sea, with carrier-based aircraft as the main combat equipment, driving on the sea surface, with conventional power, we have to specialize in ships to transport power supplies, such as fuel." But if it's nuclear-powered......"

Zhu Gaoxian remembered what the docent said when he visited a certain place, "I heard that you can sail at sea for 50 years without power replenishment." “

Zhu Gaoxian clenched his fists, "It is precisely because of this, so, even if this is a magic box, once someone opens it, they can borrow the magic power in it, and the strength of it will make people crazy, who can resist this temptation?" ”

Zhu Di can understand this, especially when someone has mastered this kind of magic, how can other countries sit idly by and turn a blind eye?

"What about you?" Zhu Di asked, "Do you also crave this kind of power?" ”

Zhu Gaoxian's hands were clenched on the wall, because he was too hard, the green tendons on the back of his hands flare up, he turned his head to look at his father, and the afterglow gilded a layer of gold on Zhu Di's body outline.

"Dad, don't you want this power?" Zhu Gaoxian said, "Mastering the core is another level of competition, and my son hopes that Daming can always be ahead of the times." ”

"Whatever you want to do, Dad will support you!" Zhu Di said, "The defense of the northwest is done by my father, if you have any ideas, you can also tell your father, you only need to do what you want." ”

Zhu Di put his hand on his son's shoulder, his son was already a head taller than him, Zhu Di was very pleased, "Don't worry, take your time!" ”
