The last time Han Yan was discovered in the Gewu Department of the Academy, the water row was born out of nowhere, after solving the problem of oxygen supply and combustion in the smelting blast furnace in Qingzhou. Liu Bei hasn't been here for a long time.

The last time I discussed with Xun Yu the trial of the imperial examination in the academy and admitted a group of scholars to enrich the county, Liu Bei came over to encourage the scholars.

The results of the imperial examinations were less than ideal, and very few people participated. And most of them are from poor families. At this time, most of the scholars came from the family of scholars. If a family is very poor, it will not be able to go to school anyway. Unless someone looks at you and grants it. The children of the family want to become a leader, and there are many ways. Visit celebrities to intervene, or recommend each other, or have the county obey the order...... And so on.

There is also a kind of person who repeatedly refuses, so that you can sit on the price, and the more times you resign, the more people in the world will expect from you. It's quite a bit that if you don't come out, what does the world mean. For example, Yuan Shao back then, and Wang Anshi in later generations. are all typical examples. And once the children of the family come out, the most important thing in the county is the county and the main book; In the county, it is either engaged or county; As for the government conquest and the imperial court summons, it is either a doctor or Langzhong. Therefore, Liu Bei intended to select people for the imperial examination to serve as the officials of the counties and counties under his command. Many of the children of the family are dismissive of this. I thought that these little officials were entangled in mundane affairs all day long, and they were turbid officials. I don't want to do it. And the people who participated in the imperial examination, except for a small number of people with lofty ambitions, the rest were poor children who did not have a good way to become a leader in their families.

The Hanmen here does not refer to ordinary people from poor families, but to the Shu people with relatively low backgrounds, such as small and medium-sized landlords in the county.

Liu Bei was bent on reforming the election system, but he was quite helpless when he ended up with such a result. can only order people to strictly recommend and employ people on the one hand, while slowly waiting for the opportunity.

Today, he came to the academy again, firstly, by the way, to visit his teacher Zheng Xuan, the old man is over seventy years old, and he should enjoy happiness at home, but now he is devoted to the academy for him.

Thanks to Liu Bei's strong support and the invention of Zuo Bo paper. Zheng Xuan has already rearranged his previous works. It was then republished and distributed all over the world. "Three Rites Note", "Mao's Poetry Biography", "Zhou Yi Note" and other scripture annotations, all of which are sected by the corporal of the world. Zheng Xuan himself is also the author of books such as "Seven Political Treatises on Astronomy" and "Zhonghou". He wrote millions of brilliant words in his lifetime. Zheng Xuan not only commented on the scriptures, but also made great contributions to phonology, exegesis, and interpretation of the law. Its role and influence on Qingzhou and even the whole of China in the inheritance and promotion of culture is very huge.

Today's Zheng Xuan is very courteous in Qingzhou, and his living conditions are much better than those in history. And he did not suffer the pain of losing a child in his later years. His beloved son, Zheng Yien, now serves his knees and takes very good care of him. Zheng Xuan is comfortable, not to mention how good this spirit is. Every day, he lectures and expounds the Bible, manages the college, and is constantly busy.

Liu Bei came over, sat with the teacher and talked for a while, and then said goodbye and came to the Gewu department. This is the main destination he came to today. Because of some strange experiments all day long, the courtyard is expanding again and again, getting bigger and bigger. As soon as Liu Bei came in, he saw a group of people gathered around, and his mouth kept making exclamations.

Liu Bei smiled outside: "Why are you so surprised? ”

Someone was impatient and wanted to reply, looked back, and saw that it was Liu Bei, and was surprised, so he hurriedly bowed deeply and said, "Meet the envoy." ”

Liu Bei shook his hand and said with a smile: "Don't be polite." Everyone came to their senses and got out of the way. Liu Bei raised his feet and walked forward, and when he saw the thing in the middle, Liu Bei couldn't help but be stunned and confused.

I saw a cauldron in the middle, and the flames were burning brightly below. The iron pot is sealed, there are several bamboo pipes on it, and there are two spheres connected to the bamboo pipes, and a small person stands on each of the spheres, fighting together with the continuous rolling of the spheres. The two villains are vivid, each raising a sword, you come and go, and the fight is not fierce. There were two people standing next to the cauldron. The seated gentleman, who looked no more than sixteen or seventeen years old, was burying his head in adding firewood under the iron pot. The one standing, with a long body and a clear voice, was giving an introduction to the onlookers. Liu Bei fixed his eyes, it wasn't Zhuge Liang, who was it?

I only heard Zhuge Liang say: "Liu Yuanjun once said that everything in the world has its own nature. The boat travels on the water with buoyancy, and the falling object is the force of gravity. After several days of observation, Deheng and I found that when we boiled water with Choshi, the lid of the pot would be lifted up by a force. This power comes from a kind of fog that is produced when the water boils. Now Deheng and I have done this little experiment, boiling water to collect the power of this mist, to see how powerful it is and what it can do. Well, through these two small balls, we can see that the power of this fog is not small......"

When he was talking, Zhuge Liang saw Liu Bei. Hurriedly stopped, and kicked the sitting Ma Jun again. Ma Jun looked up and stood up hurriedly. The two were about to worship, but Liu Bei, who came back to his senses, stopped the two of them and looked between the two with a smile.

Okay, now I'm going to start working on steam, and you're going to get me the steam engine out in a while? Zhuge Liang I know that you are erudite and talented, and the history says that you are good at ingenuity, and you are also making wooden oxen and flowing horses, and you are also building Zhuge crossbows. But now in the academy, if you don't study hard, why do you study these things all day long? Is it time to start inventing? In this case, will the future prime minister go astray and become an inventor?

Liu Bei shook his head and looked at Ma Jun again. Ma Jun, the word Deheng, Fufeng people. The family is poor, clumsy in words and good at ingenuity. Hearing that Qingzhou Academy subsidized scholars who could take the entrance examination, he begged his father to take him from west to east, spanning most of the empire, and came to Qingzhou. Later, Ma Jun lived up to expectations and was admitted to Qingzhou Academy in one fell swoop, where he was educated.

Ma Jun is a veritable great inventor and mechanical expert in history. Shi Zai not only improved the loom, but also invented the drainage and irrigation water wheel, researched and manufactured the guide car that had been lost for many years, improved the Zhuge crossbow and the stone car, and was also ordered to make a transmission puppet for Emperor Wei Ming. When he arrived at the academy, he knew that there was a science department, and he was like a fish in the sea. Completely hooked on here. Calling friends all day long, and learning with the scholars.

That day, I saw Zhuge Liang looking at a boiling water Chozi for a long time, so he stepped forward to ask, and Zhuge Liang said the reason. As a result, Ma Jun listened to it and was also very interested. The two idiots gathered together to observe, both of them were people with seven exquisite hearts, and it didn't take long for them to make a transmission machine that used water vapor as power. and demonstrated in public today.

This kind of thing that can increase knowledge and fun, as soon as it appeared, it caused a sensation in the Gewu department, so everyone spread ten, ten and hundred, and came to see it. Directly blocked this place to a solid knot.

Liu Bei gathered his mind, looked at the two of them and said with a smile: "Yes, learning from things is the most important thing to observe and practice." First the grid, and then know the reason. This fog is born from water, and it can be called steam. So Haosheng gave a few words of encouragement, and then said a few words to all the students, and then hurried to the back of the Gewu department.

After Liu Bei left, all the beings surrounded the two and kept congratulating. These two people seem to have entered the eyes of Liu Yuanjun. The future is promising. Zhuge Liang looked calm, his uncle and brother have already come out, and his future naturally does not have to worry. However, Ma Jun is a little younger, his heart is beating, and he is overjoyed to listen to the good words of all people.
