In the past, the benefits brought by a great Confucian protégé were unimaginable to countless people.

At the same time, countless people broke their heads and wanted to squeeze in.

This doesn't just mean that you can learn more unique and advanced knowledge, but you can also make more connections, more useful connections.

Even these Confucians themselves are very good connections.

Many times, even if they are only struggling for a lifetime, if they don't have a good opportunity, they can't even afford a Confucian to say a word in front of those officials.

This is also the reason why the Confucians were so popular and had such a high social status before.

Protégés are all over the world, some famous Confucians, and even a large number of high-ranking officials, and even some feudal officials.

And these students never dare to forget their mentors even if they are in high positions, one is the ideological constraints, whether it is ancient or modern, ingratitude will not have any good results, especially in ancient times, even if a person is an official to the prime minister, or mixed with the current cabinet members.

Li Yuanji doesn't care about these things the most, but if there is negative news about someone's ingratitude, then I'm sorry, even if this person is Ma Zhou, Fang Xuanling, or Xiao Yu, Li Yuanji will not hesitate to remove their official positions.

A person who doesn't even care about his own division commander, how can he put the emperor in the eyes of others in the future?

Of course, there are not many people who do such stupid things, and they can almost be described as scaly phoenix horns.

Far from doing any good, this has a lot of disadvantages.

And if you don't, the benefits are dropped.

People in high positions also need connections, and these students under the same teacher naturally become their own factions, which is also the core basis for many officials to form party henchmen.

A great Confucian protégé can bring so many benefits, but what about the protégé of the Son of Heaven?

Of course, there is also a saying that if you suffer hardship, you will become a superior person.

The process of these nineteen people becoming the protégés of the Son of Heaven is a bit unbelievable, and even they can't believe it, but this is the case, they have really become the real protégés of the Son of Heaven.

It is clearly distinguished from the previous identity, that is, from this moment on, the nineteen of them have been completely branded as emperors, and they will not be able to get rid of this brand for the rest of their lives.

Of course, no one thought of getting rid of this identity, I don't know how many people are fighting for the title of the protégé of the Son of Heaven in the four major academies, and they have become the most senior existence among the students in a daze, how can they feel dissatisfied?

It's just that the excitement is not long, and the reason for the meeting is to tell them what their next task is, what to do and what not to do.

It's also a warning to them to control themselves and not to do that kind of disappointing thing.

And then, of course, it's textbooks.

Is carbon C? Is oxygen O2?

Can anyone tell me what the hell oxygen is?

After getting the textbook, the nineteen people all looked confused, they knew the formula of mathematics, and it was not that they couldn't accept this strange thing.

But what kind of formula is this? Also, who told me how to read C? How do you read?

At this time, Datang didn't know what English was, and he didn't know what Abel Cide was, learning words and pronunciation, it was completely hard to learn, and it all relied on the brain to remember pronunciation and how to write.

Looking at the appearance of these students below, Li Yuanji sighed secretly in his heart, there is a long way to go.

Even if these are the most suitable candidates for the entire Datang at the moment, it is still difficult for them to accept such strange things.

The current situation is a little different from that of later generations, and the general environment of later generations is different from that of today, and chemistry has entered daily life, so it is easier to accept it.

And now, these inexplicable things can only leave a series of question marks in their minds, and they don't even have a prototype.

"The textbook you have in your hands is called chemistry, what is chemistry? For example, the combustion of carbon fire, for example, is explained by chemistry, that is, carbon itself is added to oxygen, and the gas produced after combustion becomes carbon dioxide, what is carbon dioxide? If you don't know, you can try to light a charcoal fire when you go back, and then put your nose on it and ask, the smell is carbon dioxide.

What can carbon dioxide do? In addition to destroying the environment, its greatest function is to kill people, in a closed room, light a pot of charcoal, in less than a night, there can be no living creatures in this room.

This is also the reason why multiple exhaust holes are built for heating stoves and heaters.

In addition, there are many other cases, you can think of everything, everything in this world, can be explained by chemistry.

Of course, what is really needed is not for you to explain the chemical formula of every thing or item in a chemical way, but when you have fully mastered this knowledge in the future, you can study more unknown things by listing chemical formulas, experimenting, and then researching more unknown things. Li Yuanji decided to tell them the importance of chemistry.

Of course, since they have become their own students, no matter what, these people are particularly important for their future, and it can even be said that how long Datang can go on the road of industrialization depends on these people.

Therefore, Li Yuanji is also more willing to talk to them a little more, which also includes what he wants to say next: "Do you know how I selected you?" ”

The crowd shook their heads, knowing that there were ghosts, and until now they were still confused, but there was no rumor in advance.

"I have listed several conditions, and the person selected must meet all the conditions, and in addition to these conditions, the process of making your decision in the first place was also arranged by me." Speaking of this, Li Yuanji paused slightly, and continued: "I am very happy that I can elect nineteen of you to become my students, but I am also very disappointed, only nineteen of you are willing, and those who do not meet the conditions will not be mentioned, and the ones that disappoint me the most and make me sad are those who meet the conditions but refuse."

But that's good, and I'm thankful for their refusal, because I'm going to be able to teach you something more freely. ”

Indeed, as Li Yuanji said, he was very disappointed, originally thinking that among the four or five thousand students, there should be at least thirty or forty qualified students.

In fact, there were twenty-eight who really met, but nine refused.

This is also the reason why Li Yuanji wants to strengthen ideological education, nine out of 28 people refuse, and this proportion is already nearly one-third, which is a result that he cannot ignore.

Therefore, we can only do some corresponding work to avoid the deterioration of the situation.

Of course, those are all afterthoughts, and they have nothing to do with these students who came to the main hall, and Li Yuanji is still quite attentive to them.

Although his own culture is not high, the education he received is different from theirs, and his horizons are broader than theirs, so there is no problem in being their teacher.

"Don't underestimate the science of chemistry, I can tell you directly that the gunpowder that is being used in Datang now is the one I used to research, and the later improvement of gunpowder, so that the gunpowder used now is more powerful than before, is also calculated and researched through this science.

Including the iron-smelting workshop, their iron-smelting technology was also studied by me using this knowledge, and there are many, many others.

I originally wanted to study it slowly, but now that the development speed of the Tang Dynasty, I don't have time to do this, and I don't want this knowledge that I have painstakingly created to disappear after my death, I want it to continue to contribute to the Tang Dynasty, and I don't want to see that one day, the Tang Dynasty will follow in the footsteps of other dynasties.

I can tell you clearly that what you are holding in your hands is only the most basic introductory knowledge, and it is just the chemical element symbols of various elements, which are very simple, but very useful, and all the calculations, if you use it instead, can not only list them clearly, but also bring unexpected results.

Therefore, at all times, keep the book in your hands and write it down in the shortest possible time, just as you should get dressed before going to the ground every day.

Although there are nineteen of you, although they are all my students, I can tell you that this does not mean that your position is secure, and every time I assign a task, the last elimination system will be adopted, and I will give each of you three chances, if the three missions are the last one, then you can only be sent home.

It's not that I won't allow you, it's that you're really not fit for this science. ”

There is no doubt that there is competition to be motivated, and Li Yuanji will naturally not give them a smooth learning space, at least not now.

Only when they meet their own requirements will this last-place elimination system be abolished, and at that time they will also be transferred to research units and research in their respective fields.

It is obviously unfair to use progress to evaluate, because some directions are destined to be difficult, and progress is destined to be very slow, but the effect is huge.

For them in the student era, this last-place elimination system is obviously still very suitable.

And Li Yuanji moved out of this system, and the nineteen people didn't feel any pressure, if you have to say pressure, it is that there are too few nineteen people, that is, the probability of everyone ranking last has increased a lot, which makes them very dangerous.

But in the academy, I have long adapted to this system, and it is a big deal to read at night.
