On the tenth day of the moon, crystal snowflakes floated in the sky, and the cold winter Bianjing enveloped it.

During the imperial city ban, Zhao Lei was walking towards the direction of the prince's bedroom in the wind and snow. He only returned to Bianjing from Xifu yesterday. He was so anxious to return to Bianjing because he was the prince's tutor and had to bear the responsibility for education.

On the fourth day of the dynasty, Zhao Zhen, the only son of the official Zhao Zhen, became the crown prince of the Song Dynasty, and the crown prince's tutor was established seven at once. After the commemoration of the Taimiao in the afternoon of the fourth day of the dynasty, the prince's tutor officially moved into the Eastern Palace to become the crown prince. The crown prince's tutor Du Yan also began to exercise the responsibility of the crown prince and taught the prince an Analects on the fourth day of the dynasty. In the next few days, Prime Minister Wang Su, the assistant minister Wang Yiyong, Zheng Jian, the three envoys Ye Qingchen, and the Privy Councilor Song Yang each took turns to teach the crown prince's homework. On the tenth day of the dynasty, it was finally Professor Zhao Lei's turn to teach the crown prince.

These days, the north wind roared and the cold snow was flying. Zhao Lei, who braved the wind and snow, had been thinking about what kind of knowledge he could teach the future emperor of the Song Dynasty and the current crown prince Zhao.

Zhao Lei learned a lot and knew a little about everything, but he was not proficient in anything. In his previous life, he was not a good student at all. He was a good player in fighting, otherwise he would not have failed to get into college and joined the army. The knowledge in medical skills was entirely influenced by his family. He was a soldier in his second year of high school and was able to teach the prince of the Northern Song Dynasty.

What to teach! Mathematics! Forget it. In my previous life, I always struggled on the passing line. Now more than ten years have passed, and a lot of knowledge has been erased by time. Besides, the mathematics exhibition in the Song Dynasty has reached the peak of feudal society. I can’t understand many of the contents in "Nine Chapters of Arithmetic". Let Ye Qingchen teach this subject! Zhao Lei was walking to the East Palace and thought of it in a bit embarrassing.

Chinese! It's a bit embarrassing to say. Zhao Lei couldn't read many traditional books in the Song Dynasty, and Zhao Lei wouldn't do anything about dancing a big sword in front of Guan Gong, a group of literary masters in the Northern Song Dynasty.

If you teach the prince English, would it be ridiculous? The second leader of the Song Dynasty and the future emperor of the Song Dynasty would have no use for learning English.

Physics and chemistry! You can teach a little, but Zhao Lei doesn’t know much, even fewer can be given to the prince.

After thinking about it, the knowledge that the Northern Song people mastered was no less than that of Zhao Lei. The only thing they lacked was the precipitation of thousands of years of history and some cutting-edge technologies. However, Zhao Lei could not produce those cutting-edge technologies such as computers and missiles. However, Zhao Lei could not teach the prince a thousand years of history, which was troubled!

When Zhao Lei saw the gate of the East Palace, he had been thinking hard for a long time and finally made up his mind to teach the prince the geography knowledge of the earth first. After all, geography is the only knowledge that has not changed much in a thousand years.

………………………………

"I have met Your Highness, Your Highness!" In the study of the East Palace, Zhao Lei respectfully bowed to the young and old Prince of Song Dynasty.

"The Grand Tutor is not a gift!" After the Chinese New Year, the prince, who was already ten years old, answered to Zhao Lei very steadily.

In the study of the East Palace, in addition to Zhao Lei and the prince, there is also an eunuch who serves the prince and a prince's daily life note.

The Daily Note is a seventh-rank official in the Song Dynasty. It is divided into two positions: the Emperor's Daily Note and the Prince's Daily Note. It is mainly responsible for recording the words and deeds of the Emperor and the Prince.

After Zhao Lei exchanged greetings with the prince, he began his first class to teach the prince.

"I wonder why the Grand Tutor taught me?" The prince looked at Zhao Lei coming empty-handedly, without bringing any books, and asked Zhao Lei curiously.

"Knowing astronomy and wise fortune, and understanding geography and understanding family and country. Today, I will teach His Highness the geography of the Song Dynasty and the entire world." Zhao Lei said loudly to the prince.

After Zhao Lei finished speaking, the prince walked down from the owner of the study and followed Zhao Lei to the professor's seat next to him. The two sat opposite each other, and there were two low desks in the middle, with four treasures in the desk neatly arranged on the desk.

Seeing that the eunuch beside the prince had already started to grind the ink, Zhao Lei asked the prince with a smile: "Do you know how many roads do I have in the Song Dynasty?"

Zhao Lei’s question made the prince a little confused. Although the prince was the prince of the Song Dynasty and knew that the Song Dynasty belonged to their Zhao family, the Zhao family had a lot of family background. The prince was really not very clear. Although the prince also knew the names of the Song Dynasty, the specific number of roads was not something that the ten-year-old prince could understand.

"How many roads do you know about your highness?" Zhao Lei asked the prince again.

"I know that there are two routes in the west and two routes in the Jingdong routes near Bianjing, as well as Yongxing Army Road, which is the battlefield for fighting against Xixia. I also know that Luzon Road is the territory just captured by the Song Dynasty, so I don't know other places." The ten-year-old prince began to answer with his fingers when he heard Zhao Lei's question.

"Okay! Your Highness knows that the Sixth Road of the Song Dynasty is already very good. Now I will tell you carefully about the various roads of the Song Dynasty!" Zhao Lei said with a smile and praise the prince.

Hearing Zhao Lei's praise, the prince was obviously excited to grab the brush and waited for Zhao Lei's teachings.

"There were five roads in the north of the Song Dynasty. Qinfeng Road was connected to Tufan in the west and Xixia in the north. Its capital was Fengxiang Prefecture, and it was under the jurisdiction of the five prefectures of Xining, Lanzhou, Qinzhou, Minzhou and Xizhou.

The Yongxing Army Road connects Xixia in the north, and is located in Yan'an Prefecture, with five prefectures under the jurisdiction of Qingzhou, Weizhou, Linzhou, Prefecture and Fengzhou.

The three routes of Hedong Road, Hebei West Road and Hebei East Road are all connected to the Liao Kingdom in the north, and are the front lines of the anti-Liao Liao. Their capitals are Taiyuan Prefecture, Zhending Prefecture and Daming Prefecture.

The North Fifth Route is the front line of war in our Song Dynasty. It has more than 200,000 imperial guards and more than 100,000 border troops. It is

The five most important defense paths." Zhao Lei said here, looking seriously, nodding with a smile, and picked up the tea at hand and sipped it.

"If the North Fifth Road is the most important military important place in our Song Dynasty, then the Jing Fourth Road is the most important political important place in our Song Dynasty. The Jing Fourth Road is Jing East Road, Jing East Road, Jing West North Road and Jing West South Road. The capitals of these four roads are Kaifeng Prefecture, Yingtian Prefecture, Yingchang Prefecture and Jingzhao Prefecture.

The Fourth Route of Beijing was stationed in the Sixteen Imperial Guards, with 400,000 troops distributed in various ways. In addition, our capital of the Song Dynasty, Bianjing, is of self-evident importance.

The Three Roads of the West are the three weakest roads in our Song Dynasty. The land of Lizhou Road is barren and the production is not large, and it is entirely supported by Chengdu Prefecture Road. The capital of Xingyuan Prefecture has a population of about two million, with few people and poor land and poor land. Although Chengdu Prefecture is rich, it has inconvenient transportation and difficult transportation. It can support Lizhou Road in addition to self-sufficient, there is no hope for anything else. Guangnan West Road is large and poor. The mountain roads are rugged and sparsely populated, and it is a place where officials are responsible. These three roads can be said to be the weakest roads in the Song Dynasty.

If the various territories of the Song Dynasty were divided by regions, besides North Fifth Road, Beijing Fourth Road and West Third Road, there were only South 9th Road and Hai Yi Road.

The so-called Nanjiu Road is the nine roads and prefectures south of Jingsi Road, namely Huainan East Road, which is the capital of Yangzhou Prefecture, Huainan West Road, which is the capital of Luzhou Prefecture, Hubei Road, which is the capital of Jiangling Prefecture, Jiangnan East Road, which is the capital of Jiangning Prefecture, Jiangnan West Road, which is the capital of Hongzhou Prefecture, Liangzhe Road, which is the capital of Hangzhou Prefecture, Fujian Road, which is the capital of Fuzhou Prefecture, Guangnan East Road, which is the capital of Guangzhou Prefecture, and Jinghu South Road, which is the capital of Tanzhou Prefecture.

Nanjiu Road is now the granary of the Great Song Dynasty. Rice ripens in Jiangnan and even ripens in the city has become the main grain for the lives of hundreds of millions of people in the Song Dynasty. Nanjiu Road can be regarded as the foundation of the Great Song Dynasty's agriculture, and it is the top priority!

In addition, the Haiyi Road is the overseas Luzon Road that the Song Dynasty had just occupied. Now Luzon is a major commercial place in our Song Dynasty. The overseas trade with the South of the Song Dynasty has to pass through Luzon Road. The annual tax revenue of Luzon Road alone reaches 30 million chunks, which is enough to support all the soldiers of the Song Dynasty." Speaking here, Zhao Lei looked at the prince who wrote quickly and asked with a smile: "Your Highness now knows how many roads I have in the Song Dynasty, right?"

Hearing Zhao Lei's inquiry, the prince stopped the brush in his hand, raised his head and replied to Zhao Lei: "Northern military towns, Beijing 4th Road, the barren West Third Road, the Granary South Ninth Road of the Song Dynasty, and the commercial town of Hai Yi Road. There are 22 roads and prefectures in the Song Dynasty."

"Not bad! There are currently twenty-two routes in the Song Dynasty, with 800,000 imperial guards and 400,000 local troops, with a population of 110 million, maybe 20 million. Your Highness can go to the Ministry of Revenue to check it out, and I am not sure about this problem." Zhao Lei said to the prince with a smile.

"The Song Dynasty has twenty-two routes, more than one million troops. There are more than one million people. Why can't the population be defeated by only ten million, and the army is only 500,000, and the Xixia, which has a narrow territory and a barren land?" The prince raised his head and asked Zhao Lei in confusion when he heard Zhao Lei's words.

When Zhao Lei heard the prince's question, he was slightly stunned, but he didn't know how to answer the prince. Could it be that Song Taizu was wary of military generals and emphasized civil and neglected military policy that caused the current military weakness of the Song Dynasty? If he said this, he would probably be pushed out by the official Zhao Zhen to cut it off soon, but in addition to this answer, is there a second answer?

The prince’s question is difficult to answer. Even in the current Song Dynasty, it is still mainly defensive in military aspects and does not have the ability to take the initiative to attack. This is no longer a question of whether weapons are advanced or not, but a question of the comprehensive quality of the army and the political environment.

Zhao Lei, who was in a dilemma, just asked the prince: "Your Highness now knows the territory of our Song Dynasty. Let's talk about the situation of the countries around the Song Dynasty! Do you know how many neighboring countries are around the Song Dynasty?"

"This father told me that the neighboring countries of the Song Dynasty are all evil wolves, the Western Xia is a evil wolf eyeing covetously, the Liao Kingdom is a evil wolf that is fed by us, the Tufan is an elderly wolf, the Dali is a evil wolf without claws and teeth, and the Yue Li Dynasty is a evil wolf that is growing up." The prince answered to Zhao Lei's conspiracy when he heard Zhao Lei's inquiry.

"This metaphor is very vivid!" Zhao Lei said with a smile and praised the prince.

"The main enemy of our Song Dynasty is still in the north. Tufan is a mess. Dali and Yue Li are both very weak, with less than 100,000 soldiers, so it is not worth fearing. Xia and Liao are the main enemies of our Song Dynasty!" Zhao Lei said with emotion as he looked at the prince.

"I know that when I grow up, I will definitely send troops to defeat the army of Xixia and Liao." The prince mentioned Xixia and Liao and waved his little fists in anger.

"Okay! It is a blessing for the country to have such ambition, but such ambition must be backed by a good body. It is better for me to teach you a set of boxing skills!" Zhao Lei said with a smile as he looked at the prince who was waving his little fists.

Seeing the prince nodding excitedly, Zhao Lei pulled the prince out of the study and handed over a set of boxing techniques from the army in his previous life to the young prince, and asked the prince to exercise every day.
