For Li Xuan, opening the imperial examination and recruiting those traditional scholars is a means of political propaganda, not that he really needs these scholars to be his officials.

Many of the talents he needed were people with modern scientific knowledge, but such talents could not be recruited directly from today's society.

In this regard, Li Xuan conceived three solutions: one is to impart modern scientific knowledge to these officers in the process of training officers; don't be surprised, if Li Xuan wants to build a real modern army, the officers must have modern scientific knowledge, and it is difficult for a person who is illiterate to lead a modern army to fight.

And this process has been implemented for almost two years since the beginning of the Guards era, and the level of science knowledge taught in the Imperial Academy, although it is still very low in the eyes of later generations, even inferior to elementary school students, but it is extremely advanced for this era, at least these officers have been brainwashed and instilled with a lot of basic scientific knowledge, especially astronomy and geography related to operations, basic mathematics, geometry, physics and chemistry.

To put it mildly, the officers in the Tang Dynasty's division, especially those who have received a complete imperial academy education, are definitely the most outstanding comprehensive talents in this era.

Although these officers are used for combat, the officers will retire, and after these retired officers are transferred to the local government, they will be able to play a great role.

In addition to officer training, there is also Guozijian education!

According to the reform of Guozijian some time ago, the Tang Dynasty merged with the Literature Hall and the Engineering School to become Guozijian, and there were two major colleges under the College of Liberal Arts and the College of Science, as well as independent departments, such as the Department of Medicine and the Department of Agriculture.

This kind of reform has made Guozijian completely different from the traditional Guozijian, saying that it is Guozijian, but it is more accurate to say that it is a comprehensive university, but unfortunately in addition to traditional Chinese studies, the level of science is relatively poor.

Guozijian and Wuxuetang and Yuxuetang are one scholar and one martial arts, and their education models are naturally completely different, the students trained by Wuxuetang and Yuxuetang are all in the military, and the students trained by Guozijian will be officials in the future.

There is no way, if you don't use being an official as an attraction, there are not many scholars who are willing to apply for Guozijian at all.

And this time, the imperial examination is political propaganda on the one hand, and on the other hand, it is also to recruit students for Guozijian.

But in addition to cultivating modern talents through the Martial Arts Hall, the Imperial Academy and the Guozijian, in fact, Li Xuan also has another training channel, and the training of this channel is more comprehensive and even more effective, that is, those teenagers in the young military camp.

At the beginning, Li Xuan's plan was relatively simple, that is, to simply treat these young military camps as orphanages, provide some basic preliminary education, and then when they are older, they will be sent to the Martial Arts Hall, the Imperial Academy Hall or the Guozijian.

Recently, however, Li Xuan had changed his initial mind, because the science courses in this young military camp were sometimes taught by him himself, and in the process he found that these teenagers were more receptive to New Year's knowledge, at least than those who had already received traditional Confucianism.

And this trend is more obvious in teenagers between the ages of seven and ten, children in this age usually do not know words, and even if they do, they have generally only read enlightenment books such as the Three Character Classic, and their three views have not yet been formed.

Therefore, their ability to accept new things is far stronger than those students in their teens or even twenties.

Even a few children with excellent academic performance, their science level has reached the level of the students of the Imperial Academy, well, and this possibility is there, because the education level of the Imperial Academy and even the Guozijian is actually equivalent to the primary school stage of later generations, or even worse.

And because these children have been learning and contacting since childhood, and they are personally taught by Li Xuan, it is reasonable that their learning progress is faster than that of Guozijian and Yuxuetang.

But this is faster, in fact, it is just the ordinary elementary school level in later generations.

However, even so, Li Xuan was overjoyed, so he specially changed the training method of the young military camp, and decided to select those children with excellent academic performance, and then Li Xuan continued to teach them personally.

In this era, no one has a deeper scientific knowledge than Li Xuan!

As for other children with average academic performance, they will no longer continue to enter the Guozijian or the Imperial Academy, but continue to study in the young military camp, anyway, the Martial Arts Hall and the Guozijian are not unable to provide a better education than the young military camp.

And implemented a new grade system in the young military camp, divided into the first grade to the twelfth grade, and this grade distinction was completely made by Li Xuan according to the elementary school to high school in later generations, and this distinction was not based on age, but on the level of knowledge.

In addition, after the implementation of the grade system, the teenagers in the young barracks were uniformly arranged, and those who failed the examination were all first-grade students, and those who passed the examination were promoted to the second grade, and then the second-grade students were examined, and those who passed were promoted to the third grade, and so on.

At present, of the more than 500 teenagers in the young barracks, one-third are still in the first grade, and another third are in the second grade, and the more senior the students, the fewer are the fewer, and by the time they reach the sixth grade stage, there are only three students left.

After adopting the grade system, Li Xuan, in order to cultivate a sense of hierarchy and obedience for them from an early age (most of these students will join the army in the future), adopted the responsibility and authority of the senior students to teach and manage the junior students, and even the teachers of the lower grades are all served by the senior students, and those with superior academic performance will have various privileges and conveniences.

For example, the top three in the lower grades and the top five in the upper grades will be personally taught by Li Xuan, especially for the three students in the sixth grade and the seven or eight students in the fifth grade, Li Xuan is personally responsible for teaching, and his original teacher is at most a teaching assistant.

At the same time, in order to avoid people from the outside world polluting their three views, a closed management is adopted.

Li Xuan actually managed the completion of the young military camp as a military school, and its management model was strict and cruel, and there was no so-called humane or democratic.

On the one hand, Li Xuan was looking forward to getting a large number of officers who had received military and scientific education since childhood and were extremely loyal through the young military camp, but in fact, he was also looking forward to getting a group of real scientific talents from these teenagers.

They don't need to be very powerful, but as long as they reach the level of junior high school students in later generations, then they are enough to play the role of R&D personnel, major engineers, and so on for this era.

For example, Li Xuan dreamed of making a steam engine several times, the principle was very simple, and several senior students in the young military camp had already begun to find a way to make an experiment.

It was a great success, with a group of fifth- and sixth-graders directing a group of blacksmiths to build a boiler, which then boiled water directly from wood and copper pipes to export the water vapor, which successfully drove the impeller to turn.

Although this device is only the simplest steam engine test device, and it is still 18,000 miles away from practicality, the success of the test proves that the steam engine can indeed be used as a power source.

As for when a truly practical steam engine will be built to propel ships, pumping machines and other equipment to move, only God knows, anyway, Li Xuan thinks that this time will not be short, and it may be extremely long.

But this kind of thing can't be rushed, it's like developing mirrors, those craftsmen haven't done it for so long, but Li Xuan is not in a hurry, just do it slowly, if it doesn't work in one year, it will take two years, and if it doesn't work in two years, it will be ten years, he won't believe that he can't do it, and he will do it in death.

He didn't want to build an atomic bomb, he just wanted to build the most primitive steam engine, and he really didn't believe that he couldn't make it after spending a few years or even more than ten years.

The reform of the young military camp is also a small measure for Li Xuan to carefully carry out modern education in later generations in this era, because the teacher is only himself, and he himself is very busy, so it is destined to be impossible to carry out on a large scale, only to train so many dozen or twenty people first, and it cannot take too much time to cultivate, but only to select the best and the strongest group of people with the strongest self-learning ability to cultivate.

Li Xuan's purpose in cultivating them was not to make them become scientists or anything like that, Li Xuan just hoped to cultivate a batch of seeds, and then let these seeds serve as teachers and teach more people.

This is also the reason why the senior students are taught the junior students in the young military camp.

Imperial Academy, Guozijian, and Young Military Camp, these are the three talent education methods that Li Xuan currently adopts, and each of them is different in terms of education methods and even the objects of students.

The students of the Imperial Academy are all active-duty officers, and these active-duty officers are soldiers who have abandoned their pens and followed Rong.

Guozijian's students are ordinary students.

The students of these two groups are generally in their teens or even twenties, and they are all adults in this era.

The students in the young military camp are all orphans, and they are young, without family constraints, and at the same time, the three views have not yet been formed, like a blank piece of paper, Li Xuan can cultivate as much as he likes.

And this time, those who have excellent grades in arithmetic and miscellaneous studies will be supplemented to study in the national prison.

However, Huang Zhiyuan is not included among these people.

As a traditional scholar, Huang Zhiyuan naturally has not had much contact, and even disdains to come into contact with those miscellaneous studies, and he can barely do arithmetic, but his strength is still the traditional Four Books and Five Classics, and his achievements in history and policy theory are also good.

After the results of the Xunzhou Prefecture Examination came out, Huang Zhiyuan was on the list with the fifty-eighth place and became the first batch of new students in the Tang Dynasty.
