Outside Bianliang City, Yang Lin took five disciples, as well as a group of miscellaneous scientists raised in his own house, and even veterinary experts, to trek through mountains and rivers to a lime mill.

The lime mill is located in a secluded valley across the river, so that the smoke from calcining lime does not affect the surrounding residents, and on the other hand, it is convenient for cutting wood and charcoal and mining limestone.

On the conical lime cellar, the chimneys are sealed, and only a small hole is exposed to smoke from it.

Several limemasons did not recognize them, but when they saw these people crowded in front of them and the guards opening the way, they knew that they were nobles, and they stood by the cellar and watched them from afar.

Wu Min, Cai Qian and others are also very puzzled, the teacher doesn't give him lectures, what do you bring yourself to this kind of place?

On the contrary, Xu Shuwei was interested again, and explained loudly to his companions that lime can be used as medicine: "If you pick wisps, kudzu leaves, deer grass, mistletoe leaves, peony, and artemisia annua leaves in May, and the lime is pounded into a ball like chicken eggs, which is exposed to the sun and dried, it can cure sores and muscles." ”

The crowd was in a state of lack of interest, the smell of smoke was very strong, and the blanks burned in the kiln were still emitting heat, and the dust was choking to the people.

Yang Lin turned around and asked, "Can the knife and arrow wounds be healed?" ”

When Uncle Xu saw that someone was cheering, he was overjoyed, and said with great energy: "Of course you can." ”

Yang Lin kept an eye on it, and continued to lead people to drill in, and after a while, the owner of the lime mill arrived when he heard the news, rubbed his hands and did not dare to step forward.

The common people of this era, it's okay to let them make a coax on both sides of the road, and it is inevitable that they will be a little shy when they meet such a big official alone.

Yang Lin stretched out his hand, and the shopkeeper nodded with a smile and said, "Xiaomin greets Shaozai." ”

Yang Lin said with a smile: "We don't mean anything else today, just to visit your workshop." If the shopkeeper is free, can you show us around? ”

Hearing Yang Lin so polite, the shopkeeper almost burst into tears and led everyone into the kiln.

As he walked, he explained: "The craftsman excavates limestone from the mountain, puts it in the kiln, spreads a layer of charcoal, and then lays a layer of limestone, piles it up to seven or eight layers, and then seals the kiln and calcines, and it comes out with lime." ”

After walking around, everyone followed Yang Lin to an open space, Yang Lin found a stone, and sat down.

The people around him no longer cared about his image, and sat down with him one after another, surrounding Yang Lin in the middle.

Picking up a stone that had not yet been calcined, and with the already cooled lime in his left hand, Yang Lin said to everyone: "You see, this stone was originally extremely hard, but it can be burned into lime but it can decorate the walls. Have you ever thought about the reasoning? Why ordinary stones, sealed kiln calcination can turn into such a useful thing, do you know the reason? ”

Everyone shook their heads like rattles.

Yang Lin continued: "Gewu Zhizhi, when you study and discuss, if you understand the secrets, can you draw inferences from one another, and turn more seemingly useless things into magic."

Before the birth of a saint, there was no Analect in the world. Many classics have not yet been published, but at that time, hundreds of schools of thought were in full bloom, all sons contended, and sages appeared frequently.

People of my generation who read should come out of books, instead of walking into books, being an old bookworm who gnaws books and memorizes by rote, drops their book bags, and is useless to say that this kind of scholar is this. ”

Wu Min and the others didn't seem to understand, and some miscellaneous scholars had already patted their thighs and applauded, and these words simply reached their hearts.

Yang Lin continued: "The sage wrote books and words to teach us the rules and principles of behavior, not to plan the path of your actions. After studying the Analects and the Mean all day long, can you surpass Confucius and Mencius? They have left their own scholarship for future generations, and what they need is for future generations to carry it forward.

You have enlightened the saint thoroughly, and you have become Confucius and Menglaozhuang, what is the use?

We already have Confucius, we don't need a second one, what we need is a new saint.

If anyone can find a way to bless all people, such as turning stones into lime, then he is the new saint. ”

Jia Xian, a math master who can open a high-power power, stood up and applauded loudly as if he had drunk fake wine, startling his friend Uncle Xu next to him.

Seeing that everyone looked at him, Jia Xian was embarrassed, scratched his head and said: "Shaozai Jinyu's good words, I can't help but applaud, don't blame you." ”

Uncle Xu tugged at his sleeve slightly, signaling him to sit down quickly and not be embarrassed again.

Jia Xian had no reason not to be excited, and Yang Lin's words gave great encouragement to this incomprehensible mathematician. And Yang Shaozai is not just talking, he has promised to give him a preface to his new book, and it will be printed and distributed.

A school of doctrine, whether it can be passed on, what you have done all your life, whether it will be all lost, and whether people can leave a name after a hundred years.

All of this comes down to whether or not you can write a book, otherwise it will be passed on by word of mouth, and I don't know when it will be cut off. Moreover, everyone's understanding is limited, and the apprentices they receive may not have the talent in this area, and many academic studies in ancient China were lost in this way.

Although Jia Xian was very uncomfortable, he still hugged Yang Lin deeply, and the latter gave him an encouraging look, which made Jia Xian excited.

Yang Lin looked at several students and found that they were all thoughtful, even frowning.

The words of my own teacher are not quite the same as the indoctrination I received in the past, and everyone can be sanctified, didn't I learn it from the articles of the saints?

However, if you think about it carefully, there is indeed some truth, since the sage established the book, I have not heard of any great Confucian who can be holy.

Everyone sat in the valley, gradually getting a little cold, and Yang Lin said loudly: "That's it here today, let's go back." ”

It's okay to take them out for a walkaround, which can be regarded as exercising for these nerds, and it doesn't make sense to explain the big truths to these people in the pulpit and in the study, so you have to go deep into the ground, and change these people's deep-rooted views little by little, so that they can learn to think, learn to question, learn to be down-to-earth, and learn to have something to say.

A few nerds and a group of miscellaneous scholars, all of them are a little physically exhausted, they are not Yang Lin, and they are not served by Baduanjin, Wuxing Boxing, ginseng soup, and fur dog bian every day.

Yang Lin didn't want to eat a fat man in one bite, and said loudly: "That's all for today, and we'll continue tomorrow." ”

When everyone heard this, they complained bitterly, Wu Min, Cai Qian and others did not dare to lament, but they also had a sad face.

Yang Lin chuckled lightly and scolded with a smile: "You inferior goods, if you don't move, your skin will be rusty and hairy." Tomorrow we don't have to drill into the mountains, let's go to the weaving mill and have a look. ”

Now from the south of the Yangtze River, especially from Suzhou, there is a kind of hydraulic textile wheel, which is the beginning of machine workmanship recognized by later generations.

When everyone heard that it was an activity in Bianliang City, they immediately turned their worries into joy, and followed Yang Lin out of the mountains slowly.

Yang Lin slowed down and deliberately walked at the back, looking at their backs, with a look of relief and pride in his eyes.
