The merchants were the first to notice the charm of this book "A Brief Explanation of Mathematical Science". The formula of the Nine-Nine Multiplication has already made all the shopkeepers feel like they have gained a treasure. As for the algebraic equations and other aspects behind them, they dare not be interested.

Although it is cruel, this is the fact. What people use the most in daily life is the formula of multiplication... If you don’t believe it, think about it carefully. You have encountered several problems in your life that require equations to solve.

Of course, Lu Xuan's move also caused great controversy. On the market, a large number of literati actually appeared, opposing Lu Xuan's random spread of knowledge.

"The so-called Tao cannot be taught lightly, and the law cannot be passed on lightly..." Some people even came to Lu Xuan to debate, trying to convince him to cancel this act of spreading knowledge at will. Because this behavior will cause some ancient groups to lose some of the foundation for their survival. However, the debater was dragged out by a group of vicious soldiers just after he opened his head.

Only then did people recall the person who wrote "A Brief Explanation of the Mathematical Learning". He was a dignified general of the country and the top tyrant who was in charge of more than 20,000 imperial guards inside and outside Chang'an City. How could ordinary people speak well?

From ancient times to the present, the reason why various schools of thought have survived forever is that they are in line with the right side and the large number of people. Their biggest advantage is that they have mastered various knowledge and the right to interpret various classic knowledge. Simply put, they have the right to disseminate knowledge.

When will knowledge be spread to those people, and how to explain it, they have the final say. But now, some bad signs have emerged. First, the printing of movable type has greatly reduced the cost of books. A large number of poor children who originally needed to rely on them to read books can now buy books themselves.

Before they could think of how to deal with this situation, Lu Xuan began to spread all kinds of dangerous knowledge for free without reason. This was a more dangerous signal. Although he was only spreading some mathematical problems now, who knew what would happen next? They had to be unaware of it.

It’s a pity that Lu Xuan is a military general with heavy troops and never likes to reason with cultural people like them. The so-called fear of hooligans being educated is what he is talking about.

Lu Xuan didn't intend to pay attention to these arguments outside. He devoted all his spirit to sorting out and creating.

After "A Brief Explanation of Mathematical Science", Lu Xuan began to compile basic physics and gave the name "Theory of All Things".

Volume 1: The form of matter

Take water as an example. Cold means ice, which is solid. Warm means water, which is liquid. Hot means fog, which is gas.

Water is the source of all things in the world, so it is inferred from this. All things in the world have the above three forms...

If "The First Explanation of Mathematical Science" only caused a sensation among merchants, then "Theory of All Things" can be called a tsunami.

The book is divided into seven volumes. The form of matter in the first volume, the properties of matter in the second volume, the movement of matter in the third volume, the sound of matter in the fourth volume, the light of the fifth volume, the basic mechanics of the sixth volume, and the buoyancy density of the seventh volume. Lu Xuan thought of so much for a moment, and the subsequent ones will be added and modified at any time.

"The Principle of All Things" caused a huge shock in the world. The main reason is that this book gives a simple and terrifying explanation of the various natural disasters in this world.

‘Wind, frost, rain and snow are the three states of water. Steel can also be melted into liquid state. If it is heated to extreme heat, can it be transformed into gas state? Is there any change in the three forms in the world? This is to be confirmed by later generations...’

‘After shouting in the valley, after a moment, the same sound will be heard. From this we can see that the sound will be bounced back by the mountains. If we know the distance of the mountains, can we find out the speed of the sound? How fast is the sound? It is for later generations to confirm...'

'Light......'

Lu Xuan did not give an answer to many questions, but just raised one question. However, humans are born curious creatures. As long as this question exists in the world, someone will inevitably spare no effort to solve it.

As soon as "The Principles of All Things" was released, the entire Chang'an City was in an instant. Those principles that exist in all aspects of life, but have never been truly understood by anyone, were suddenly peeled off, crushed, and then thrown in front of the world.

Born as a human being, there are always questions. But before, those questions were vague. Now, everything is clearly placed in front of you, pointing out the way. Even if many things only come up with one direction, the clarity and impact still make people feel an unprecedented shock.

As soon as "The Principle of All Things" was released, Chang'an City had a clear change. No one called Lu Xuan a barbarian of the Western Regions anymore. What everyone is discussing now is which star lord Lu Xuan came to earth...

"Lu Lang, are you really not a god descending to earth?" Xu Hezi and Wuer looked at him with a gaze, expecting him to say yes.

"God? In your imagination, what do gods look like?"

"I know, I know, that is, the kind that can live forever, call the wind and rain, and subdue demons and demons. It's like the story my son-in-law told Wu'er."

"Is that true? That son-in-law really can't do it."

"But my son-in-law knows so many things that no one else can't do. What if it's not a god? Everyone eats better and wears better. Even the baby's ones will not die easily. Isn't this what a god should do?"

The so-called baby will not die because Lu Xuan tried to promote the disinfection procedure during the delivery process. To be honest, this was the most difficult thing Lu Xuan did when he came to this world.

You don’t know how profound the ancient people’s various taboos, prejudices, and unlucky ideas were about having children. No one was willing to try it just by disinfecting boiling water and alcohol. Lu Xuan could only start promoting alcohol boiling water disinfection in the army now. Let the military see the benefits of this method, and then with the help of the court, he began to promote it.

Even so, after leaving Chang'an City, these things were still not truly circulated. Lu Xuan didn't care about this either. He couldn't hold a knife and force others to believe him. But time would. Time would make everyone realize that this method was right, and then they would make a choice.

"Wu'er, Lu Lang is not the kind of immortal who can summon wind and rain. But he can make the people eat better and wear warmer. He is the god of the people in the world, the god of the Tang Dynasty..."

Lu Xuan stopped Xu Hezi and hugged her in his arms.
