"Okay, I'll leave the daily teaching here to you in the future, you've learned almost the basics, and I'll take the time to continue teaching you more esoteric things." Zhang Hao said.

"Teacher, you said there is something more profound?" A group of students asked, their eyes wide.

"Of course, it's just that I don't understand many more profound things very well, so I can only tell you what I know, and as for how much you can use in the future, it's up to you." Zhang Hao nodded and said.

"The teachers don't understand very well, can we?" Some students said with sad faces.

"Of course you can, there is a specialization in the art industry, my energy is not all focused on this aspect, you will definitely do better than me." Zhang Hao said with a smile, he was pointing to these people to surprise him, it was not okay to have no confidence so early.

"Teacher, we won't let you down." The students said with a firm face.

"I'm looking forward to your performance, today let's learn new knowledge, help me build a fire and boil some hot water." Zhang Hao nodded and ordered.

That's right, Zhang Hao is ready to tell the students about the knowledge of the steam engine, this is also the moment that Zhang Hao is looking forward to.

The emergence of the steam engine in history directly created an era, the widespread use of the steam engine, promoted the mechanization of various departments, with the first industrial revolution, so that the productive forces have never seen a rapid development in human history.

In terms of production, it provides a strong driving force for the development of the entire industrial sector and promotes the rapid development of industry.

In terms of life, it has promoted the innovation of the transportation industry, invented some new means of transportation, such as steamboats and trains, which greatly facilitated human travel and rapidly expanded the scope of human activities.

Zhang Hao is especially looking forward to how much benefit it will bring if there is a steam engine in this era, but Zhang Hao also knows that these things are not in a hurry.

Even if Zhang Hao imparts the knowledge he brings to these people, I am afraid that it will take a long time for the steam engine to appear, and if it wants to be used in various fields maturely, it will take a lot of time.

For a long time, Zhang Hao spent time with these students, hoping to speed up the birth of the steam engine, but he did not directly participate in it except for giving them answers.

During this period, the imperial court also sent a holy edict, and sure enough, the newly acquired land was assigned to Xuansu County, and Zhang Hao was only praised once, and his official position was not promoted at all, nor did he receive any substantial rewards.

Zhang Hao could only accept it reluctantly, it seemed that the previous reward was too high, and then there were several forces that found that Zhang Hao had been out of their control and didn't want to help him anymore.

As for the officials appointed by the imperial court to the newly occupied city, they were naturally set up in the air, and after receiving the news, Gongsun Du personally went to Xuansu to see Gongsun Chen.

Gongsun Chen was also very happy, and directly invited Zhang Hao to send some people to assist him in handling political affairs, obviously to delegate power to hand over Xuanwu to Zhang Hao to take care of.

It is not difficult to understand that he can do this, first of all, under Zhang Hao's governance, the people of Liaodong are indeed living more and more prosperous, and handing over Xuansu to Zhang Hao is also a good thing for the people.

The most important thing is that he has no children under his knees, and as he gets older, he doesn't bother to fight for anything, and he treats Gongsun Du as his own, and puts his future on Gongsun Du.

It seems that Xuanwu County was handed over to Zhang Hao's care, but in fact, it was just to increase the capital of Gongsun Du in Zhang Hao's group, and he could feel that Zhang Hao's achievements were by no means just a county guard.

The more capital is added to Gongsun Du's hands, after Zhang Hao soars in the future, the greater the benefits Gongsun Du gets, and the more comfortable he will be.

After receiving the news, Zhang Hao selected a large number of personnel to rush to Xuanwu County, half of which were selected from the counties of Liaodong, and the other half were selected from the Academy of Letters.

With the help of Gongsun Chen, these people were quickly arranged to various positions in each county in the county, and took over all aspects of political affairs.

Xuanwu County is different from when Zhang Hao first came to Liaodong, Gongsun Chen has been operating there for a long time, and all aspects are basically under his control.

In addition to political affairs, the military aspect was also fully taken over by Zhang Hao, and some grassroots officers were sent to Xuansu's army, and Bu Ji, who was stationed in Xinghuo Village, was directly promoted.

In less than a month, Zhang Hao peacefully took over Xuansu County and brought with him all the policies of Liaodong, including the abolition of all aristocratic privileges.

Although this move also caused dissatisfaction among many nobles, under the double pressure of Zhang Hao and Gongsun Chen, it did not make any big waves.

After he learned about Zhang Hao's iron and bloody wrist when he first arrived in Liaodong, he didn't dare to engage in any joint confrontation anymore, besides, the territory of Xuansu was not as big as Liaodong, and there were few cities, and the gate valve clan was naturally not as much as Liaodong.

Some of them learned that those families in Liaodong who gave up their aristocratic rights to follow Zhang Hao now chose to accept it happily when they were living a very prosperous life.

As for those who were unwilling to give up their aristocratic privileges, they did not dare to challenge them because they were afraid of Gongsun Chen and Zhang Hao, and moved to other places with their families.

Due to the relatively fast transition, it was completely stabilized before spring ploughing, and naturally the new crops were also promoted, because a lot of results have been achieved in Liaodong, and the people are also very cooperative in cultivating new crops.

As for the bandits and rogues who were mixed with the refugees, after all the refugees were naturalized in the city of Qisheng, there were several adventures to rush back to Liaodong to loot.

But under the attack of Zhao Yun with the newly formed Dragon Martial Battalion, all of them have become whetstones for sharpening recruits, and the rest of them don't dare to emerge.

Especially after the Qisheng Bone City settled down, they had given up the idea of going out to loot again, quietly destroyed their weapons, and lived the life of ordinary people.

After this incident, Gongsun Zhao also temporarily died down, he should be hiding in a corner waiting for the opportunity, or he was brewing a bigger conspiracy.

The whole Liaodong, including Xuansu, has entered a stage of stable development, and with the application of tools such as keel waterwheels, the grain harvest is also getting higher and higher year by year.

As the food reserves became more and more abundant, and the number of displaced people who fled from other places also came, Zhang Hao also issued an order in the county to encourage childbearing, and the population of Liaodong continued to increase.

And many of the Goguryeo people who were arrested have already accepted Han culture, and have been assigned to various counties and naturalized through their own performance, which is also a big supplement to the population of Liaodong.

At this moment, a letter from Luoyang broke the peace......
