"Is it in Shanggu County? That's not very far away. I know. There was already a canal communication last year. I will deal with this matter when I return to Jicheng!" Sima Ji nodded indifferently, letting the farmer in coarse linen retreat.

Otherwise, why is Youzhou a good place? There are coal fields in the west and iron ore in the east, and Yanshan as a barrier. Unicom is a natural military center outside the border. As long as the stability of the Northeast region is ensured, it is basically in a position where it is difficult to lose.

Before the Tang Dynasty, the eastern forces could not defeat the Guanzhong forces, but Sima Ji knew that once North China and Northeast China were really connected, Guanzhong would definitely not be a problem anymore. This is why Guanzhong declined after the Northern Song Dynasty, and the geographical advantage of Guanzhong could no longer stop the crushing of the eastern forces. The reason why Guanzhong could be a base before the Tang Dynasty was that the entire North China was not completed, and the population of the two sides was not huge, so the geographical advantage was still useful.

However, the carrying capacity of the millions of people in Guanzhong after the Northern Song Dynasty was impossible to be a match for tens of millions of people in North China, and the geographical advantage could not be brought back. If you guessed correctly, the current coalfield should be the coalfield in western Beijing.

Once coalfields are available, they are definitely enough. Even a country like Japan that lacks resources can use its own coal to start the industrial revolution, but Japan's coal is only enough for the early industrial revolution.

However, Sima Ji cannot use the coal fields to do anything. Can he burn fire? If one of these two things is temporarily missing, the value of the other will be greatly reduced.

"There is no war now, protect this military camp well, and most people are not allowed to approach it. Only those who hold the token of the Yan Prince's Mansion can enter. Of course, the lieutenant is exceptional." Sima Ji did not forget to say to Yang Qian, who didn't know when he would get a lunch box, "It turned out to be a military camp. According to everything in the military camp, the sergeant, the chief of sergeant, the chief of sergeant, the chief of sergeant, and the chief of sergeant were set up to manage a hundred people for study and training."

"When you are growing up, meat is inevitable, and you have meat every week. However, the pigs need to be killed by students themselves. Even if you can't do everything, I hope that the military camp will be self-sufficient as much as possible. They are all children of ordinary people, and hard work should not be a problem. As for the teacher I found, the courses taught are based on my teaching materials. I am a teacher and mainly use miscellaneous studies."

It is of course the best to be self-sufficient, because if you can't do it, it's equivalent to spending money, spending money from the Yanwang Mansion.

Sima Ji was like a chatterbox and pointed at the military camp wherever he walked around the barracks, and he should have improved it again. In fact, he should have done these things last time, but he was disgusted at that time and was carried back by someone, so he naturally couldn't take care of them.

Just because King Yan was not a person who gave up halfway, wouldn’t he come back to make up for the lessons this time? This time he came prepared and brought some military management regulations, including diet, daily life, training, courses, etc. Of course, Sima Ji would never reveal that he was lazy and changed the subject and object of the document he wrote to Youzhou Prison last time.

But I believe there will be no major problems. Controlling things is similar, and the essence is to improve discipline.

After walking around, people asked people to find all the children. Sima Ji stood tall and couldn't help but feel very passionate. He felt that only Sima Ji and Sima Qingxuan's ears were the only heroes in the world. He held the loudspeaker and shouted, "Rise your right hand up..."

Brush! The uneven arms were raised high, and Sima Ji couldn't tell at all that one hand was a little more. In order to see the feeling of Sima Ji and Sima Qingxuan disappear without a trace, he turned around and said quietly, "Gentlemen, I need to train more. I will come again next time, I don't want to see this scene. I will go back to my house now..."

Anyway, the first page of the textbook he gave was originally written by King Yan. The causal relationship and historical significance of the division of the three families with the return of the Three Kingdoms, and the historical significance of the three families with the rebellious officials and traitors in the Warring States Period, as well as the correction of the chaos in contemporary history. There are comments later, this chapter is the focus, and we will take the exam in the future...

At least the king of Yan is still rich and powerful, because the salt drying field on the beach has already produced, so it is necessary to clearly point out the problems of big neck diseases in many people and the side effects of big neck diseases, and at the same time show the superiority and health of sea salt. Sima Ji does not need to do business with despicable tricks. Although he is blowing, he can blow it with a basis.

"Xiaomin has found this kind of graphite in Shanggu County..." The tenant who was kneeling under Sima Ji just spoke, and was interrupted by Sima Ji, "I only said it once. This thing is called coal, not graphite."

"Yes, it's coal. The little people found coal in Shanggu County." The tenant immediately changed his words, and the chicken nodded like a rice-pecking expression.

"Continue!" Sima Ji leaned on the chair and felt like he had no bones, and his every move was filled with the gap between the gentry and the bottom. He had to let the tenants change their words because graphite was another thing in his eyes.

Coal must have been used in China for a long time, but Sima Ji had reservations about how widely it was used. Bingzhou is so close that he had never heard of the common use of carbonite. Bingzhou was the coal capital of China in later generations. This shows that coal has not yet penetrated into the people.

"Feng Ji!" After hearing the beginning and end, Sima Ji said to the chief clerk Feng Ji, "Go and circle me around that place, there is no difficulty."

How could his own ban on the country be difficult? Feng Ji took the order to retreat, but happened to see the recording officer Tong Jiang hurriedly walked in and reported, "The recording officer of Fan Yang Kingdom is a letter to the minister. Two royal families are coming to Jicheng. They have already settled in Fan Yang Kingdom yesterday. Today is coming. Should Your Highness prepare?"

"Two royal families? Who are they?" Sima Ji was a little unhappy. It would definitely be no good if he could run so far.

"Changsha King Sima Yi, King Fanyang King Sima Xu, calculate the time. If you set off in the morning, you will definitely arrive in Jicheng at noon tomorrow!" Tong Jiang asked carefully, "Are you going to prepare?"

"It's enough to be careful about the preparations of the royal palace. You can prepare outside the royal palace." Sima Ji was a little confused when he waved his hand to let Tong Jiang go down. Sima Yi's brother, King of Chu, Sima Wei, had just arrived in Luoyang. If he didn't help the King of Chu kill Yang, why did he come here to do it?

"There is a unique atmosphere in Yan State. I heard that Brother Qingxuan reorganized all the tenants and slaves of the entire country in one winter and planned to build houses at the garrison. This efficiency was unprecedented." Sima Yi, who was riding on a horse, couldn't help but sigh when he thought about what he had seen and heard along the way.

The villages passed by were all neatly arranged, because Fan Yang State and Yan State were adjacent to each other, this comparison made Sima Su very embarrassed.
