Han Dao world

Chapter 1073
In the seven or eight years since he came to this era, Liu Xie has not said it once, so as not to be too shocking.

Still can't today.

But he can finally say more without having to worry so much.

The ten-year-old children in the hall don't understand, even if they hear something and spread it, others may not take it seriously.

The teachers in the classroom all study military affairs, and confidentiality is the basic quality. Even if they feel something is wrong, they will not talk about it casually.

With less worries, Liu Xie can talk more and instill what he thinks is the most fundamental thing.

In addition to the principle that martial arts is practical and that we must seek truth from facts, Liu Xie also talked about some specific examples.

He took out the prepared glass sheet and demonstrated the refraction of light.

It is not uncommon for colored glaze to be glass, especially with the unimpeded commercial roads in the Western Regions, more and better glazed products entered the Central Plains, but they were just imitations of jade and used as ornaments. Almost no one realized the hugeness contained in it. value.

Liu Xie chose these two pieces of colored glaze, which are not only pure, without air bubbles, but also polished very well.When doing an optical demonstration, the outline can barely be seen.

He demonstrated two functions: one is magnification, and the other is telephoto.

The two functions are actually one, but the telephoto function is more complicated to realize, requiring a combination of two lenses.

But the effect is extremely shocking.

Yu Fan and the others all studied military affairs, so they naturally knew what looking into the distance meant.

Especially on the endless grassland, the sooner the opponent is found, the greater the chance of survival.It can also be used to transmit messages, which can also double the efficiency.

All in all, the potential value is enormous.

Many people have seen colored glaze tablets, and even have them on hand. They are also commonly used in the army to make fire, but the color is not as pure as Liu Xie's.It is also because of this that many people do not realize that there is such a function hidden behind the mottled light and shadow.

What does it mean to know a work by seeing the small things, what is it called to observe the details clearly, and what is it to know ten things from one point?

The emperor in front of him is.

All of a sudden, the worship of Liu Xie in the hall and the hall came rushing in like a torrent of water.

Even the always conceited Yu Fan stroked his beard and sighed with emotion.

Compared with the emperor, he is still slightly inferior.

This is a gap in talent, which cannot be made up by hard work.

"A small piece of glass can produce such a wonderful effect. If you can study its principles deeply and make use of it, how many secrets can you discover?" Liu Xie held up the glass piece with a smile like a spring breeze on his face. "We might as well assume that since it is possible to focus light on fire, is it possible to invent a weapon that can burn down enemy warships and camps hundreds of steps away? Can you see clearly?"

The children in the hall were so excited that they forgot the ceremony of the emperor and ministers, and clapped their hands.

Yu Fan and the others in the hall couldn't help but feel their hearts surge and their blood boil.

Not to mention creating the kind of artifact Liu Xie imagined, as long as it can have one-tenth of the effect, it is enough to change the situation on the battlefield.

For example, use several large mirrors to illuminate the face of the enemy general from a distance, making him unable to see things, and even blinding him.

For example, scouts can observe the deployment of the other party's camp from several miles away, not only can they see it clearly, but they can also ensure their own safety.

Two small pieces of colored glaze, containing infinite possibilities, waiting for them to pout.

They couldn't hold back anymore, they didn't want to listen to Liu Xie's talk anymore, they just wanted to get together to discuss and see what solutions they could devise.

-

First class, very successful.

Liu Xie not only expressed his high regard for technology, but also revealed the huge potential contained in technology. He was able to persuade Yu Fan and others to strengthen their research on technology, and recruited talents with extraordinary talents to make up for Huang Yueying and others. vacancy left.

As the foundation of all academics, arithmetic has also been raised to an unprecedented height.

As a master of Yi Xue, Yu Fan's arithmetic ability is not weak.His arithmetic played an important role in the development of the trebuchet.However, after discussing the refraction phenomenon of glass mirrors with Liu Xie, he had to admit that his arithmetic was not as good as he imagined.

At least in terms of shape (geometry), he is far inferior to the Son of Heaven.

Watching Liu Xie draw a few lines and deduce the Pythagorean theorem, Yu Fan's self-confidence was hit hard.

Sure enough, Yelang is still arrogant and generous.

Yu Fan asked if Liu could co-organize a make-up class for the teachers in the lecture hall to learn about mathematics, especially the knowledge of shape.

Similar calculation methods are also involved in Nine Chapters of Arithmetic, but they are not concise enough and often very cumbersome, making it difficult for ordinary soldiers to master.And it would be too wasteful to send those who can master it to the front line as scouts.

If Liu Xie can simplify similar methods so that ordinary soldiers can also master them, it will have a great effect on collecting information on the battlefield.

Liu Xie readily agreed, and decided to participate in the compilation of relevant Chinese and foreign classics.

Yu Fan was overjoyed, and immediately drew up a list, less than ten people in total.

Being able to listen to the emperor personally lecture on arithmetic, even if you don't talk about how much knowledge you can learn, this honor alone is worth bragging about for a lifetime.Therefore, the limited number of places has become the target of everyone's competition.Yu Fan was also polite, besides his own participation, he directly added Lu Yi and Sun Shangxiang.

Some teachers were very dissatisfied, and directly reported to Liu Xie, saying that Yu Fan was using his power for personal gain.

Who doesn't know that Lu Yi and Sun Shangxiang are his apprentices?
Moreover, they are all from Jiangdong. This is a way of forming cliques and discriminating against people from Kansai.

They quarreled so badly that word got out.

Advocating Lao Tzu, Liu Xian, who was originally very calm, couldn't sit still when he heard the news. He approached Situ Yang Biao to intercede and asked his nephew Zhou Buyi to be added to the list.

It turned out that Zhou Buyi could take the exam in the martial arts hall, but he gave up this opportunity because of the overall situation.But the emperor privately taught arithmetic, this opportunity should not be missed.After all, this is not a normal class, this time it is over, who knows if there will be another one.

After weighing it for a while, Yang Biao accepted Liu Xian's request and explained to Liu Xie.

In order to take care of the mood of Jiangnan scholar-bureaucrats, it is better to accept Zhou Buyi as Tong Zilang in advance.

Liu Xie did not agree to Yang Biao immediately, but summoned Liu Xian.

After a brief exchange of pleasantries, he asked Liu Xian a question:
When Liu Biao was in Jingzhou, the four counties in the south of the Yangtze River were not very obedient. Zhang Xian, the prefect of Changsha, even had a direct conflict with Liu Biao.Now that Liu Biao has left Jingzhou, and I have come to Jingzhou, you have put on a non-cooperative attitude and want to seek justice for Liu Biao.Are you opposing it for the sake of opposing it, or do you think that Jiangnan has natural dangers, and you can separate one side and ask for prices?

After Liu Xian heard this, his expression changed, and he looked at Liu Xie in astonishment.

"Why did your Majesty say this?"

Liu Xie's face was gloomy. "Then what do you think I should say? Appreciate you for being upright, or praise you for being rich and powerful, and for being powerful and unyielding? Although there is no Ma Fubo now, Yizhou will be settled, and there are many soldiers who still have unfinished business. If necessary, I don't mind." Let them go to Jiangnan and try the new tactics developed by the martial arts hall."

Liu Xian lost his composure and was sweating profusely.

Liu Xie leaned back, crossed his fingers, and hugged him in front of his belly. "Thank you for sending letters to your relatives and friends. They don't want to enter the court, and the court doesn't force it, but they have to do it. I'll give them another half a year. If there are still people who refuse to spend the land before the end of the year, I will send elite soldiers to supervise, if necessary , I don’t mind going there myself.”
