It is just an excuse to consider the victims of the household registration. It is not considered an excuse for the household registration. It is simply a hooligan. The so-called Five Barbarians, namely the Xiongnu, Xianbei, Jie, Di, Qiang tribes, many of them engaged in agriculture and sericulture in the Central Plains. In the past, these tribes had no land in the Central Plains. After participating in the land occupation system, they were taxed by the Jin Dynasty like the Jin Dynasty. However, tribes that did not participate in the land occupation system had to pay Yimi to the Luoyang court, with three liters per household, five dou for each household, and especially far away, they had to pay the money according to the standard of twenty-eight liters per person.

When Sima Ji needed the Hu people to pay taxes, the Hu people were my people of the Great Jin Dynasty. When the feudal state was kept intact, the Hu people were a group of people outside the world. This standard was set by the King of Yan. At present, the Hu people are not considered to be the people of the Great Jin Dynasty, and the King of Yan could take advantage of it.

This is not the case with the Xianbei tribe and the Jurchen tribe who could borrow troops at that time. As long as the Luoyang central center is unstable, he can gather a large army overnight, and the number of people is no less than that of An Lushan, who is surrounded by the governor of the Three Towns.

The Jin Dynasty had regulations on the land occupation system. While determining the land area occupied by officials of different grades, the Jin Dynasty also stipulated the number of food and clothing customers and tenants. The king and prince could raise three households of diners in fifty hectares. Diners were the guests of the Warring States Period and were the families of the host family. If the King of Yan wanted to do something about this, he could calculate the land of the country's enfeoffment, and in theory he could raise 50,000 diners. However, it could not be calculated like this. They all followed the farmland of the country's enfeoffment and raised people, and everyone did this.

"Tongjiang, check how many strong men are there. After all, there are still many projects for the ban on the country." Sima Ji waved his hand and asked Tongjiang to go down. With food and people, what is left is the most important thing. No one can go to war with bare hands, right?

I have to say that Sima Ji was completely asking nonsense, Feng Ji and the other were in charge of people and the other was in charge of grain. As for other things that were added to the cake, such as cloth, lacquerware, caravans, and fleets, they were all controlled by Yan Yan.

Of course, it is not all that is icing on the cake. It is better to say coal and iron. These two things are not icing on the cake, but rather fatal things. "Beiping County, if it is sufficient manpower and starts working day and night, how much iron can it be produced in a year? Has the armor that I asked in the first place been made?" Sima Ji asked at Yan Yan, who was left.

"The armor is already in place, with a total of 12,000 pieces. As for your Highness's other question, Yan Yan can't answer!" Yan Yan smiled bitterly, "Your Highness has ordered all the mountains of the country to be sealed and the people are not allowed to enter. There are many iron ore in Beiping County, but it is impossible to imagine how much iron can be produced after all construction starts."

"Just give me a rough number!" Sima Ji thought that it seemed that he was asking wrong, and then waited for Yan Yan to answer.

Yan Yan pondered for a moment, then stood in front of Sima Ji and calculated it, and gave an answer, "If the existing hydraulic machinery is not added, just fill in all the people needed by hydraulic machinery, about 400,000 kilograms per month."

More than 20,000 tons a year? Sima Ji's eyes lit up and he was very satisfied with this number. Of course, it was incomparable to the output of more than 100 million in later generations. But it could still be compared with the Republic of China under the rule of Marshal Chang Kaishen. After all, in the golden decade under the rule of Chang Gong, the steel output could be compared with the prosperous Tang Dynasty, and the country was almost destroyed. After eight years of the Anti-Japanese War, the output of 40,000 tons of steel was almost achieved, which was barely half of the annual steel output of the Westernization Movement in the late Qing Dynasty.

The King of Yan can compare with the current countries in the 20th century, and there seems to be nothing dissatisfied with it. If he could make nails, he could almost lead China to leap for more than ten centuries. After all, the Republic of China could not even make nails and still had to be imported.

If the country is a person, steel is the bone of a person. If the Han Dynasty can ultimately achieve victory over the Huns, the difference between the two sides is definitely not the race difference, or the Han Dynasty's own production capacity is far superior to that of the Huns without metallurgical technology. Only by wearing armor and holding iron tools can one Han be the Five Barbarians.

It would be difficult for the Tang Dynasty to touch Arabs. The Arabs who met Tang Dynasty would also be able to do so. The weapons in their hands were Modao against Arab scimitars. The confrontation of civilizations of the same level would not be a beating tribes. There was only one Hun who had the bronze ware as treasures, and there would be no other one.

"The slaves purchased by the Xianbei tribe can be sent to the iron ore, and this matter will be left to you." Is there insufficient labor? It is not a big deal. If the canal is really not dug, you can send prisoners of war to the mountains to mine. Anyway, Sima Ji had said a long time ago that as long as he thought, the project in Youzhou would never be completed.

When Yan Yan also left, Sima Ji was the only one waiting in the inner palace. Why didn’t the students he was optimistic about come yet?

After a long time, Luo Yong walked into the inner hall panting and said before Sima Ji could ask, "Your Highness atonement, Luo Yong is still supervising the worker in the ditch. He didn't know that Your Highness had returned to Jicheng, so he rushed over."

"It's okay, I haven't waited for long." Seeing the other party's appearance, Sima Ji was embarrassed to scold him. He calmed down and waited for Luo Yong to straighten his breath before asking, "I won't say anything else. I heard that the canal has not been completed yet, so I want to ask, how long will it take at the fastest?"

"This, in the past few months, prisoners of war have caused troubles, and the tight guard of the Youzhou army has not caused great chaos." Luo Yong spoke in a little embarrassedly, looking at the face of King Yan, fearing that the words would anger the King Yan.

"I asked when I could finish the work? I didn't ask if I had any trouble. Just look at your expression and you will know that all the prisoners of war who caused trouble must be rotten!" Sima Ji asked with an impatient look, "Tell me about time, what if I don't finish it?"

"Three months, if it is not completed, the villain will come to see you." Luo Yong was snatched away and he was stunned and gritted his teeth and promised.

Did you push yourself too hard? Sima Ji was also stunned and said slowly, "It's not that serious. You can only serve me when you are alive, but some punishments are inevitable."

"The construction will be completed within three months, and the time limit will be subject to His Highness's disposal." Luo Yong said directly, "I am willing to issue a military order."
Chapter completed!
