When Lu Cheng returned home, he didn't feel much sleepy for the time being, so he planned to practice calligraphy in the study for a while before going to sleep. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In those days, there were no electric lights, and it was not very convenient to read and write at night. However, the moonlight is very bright tonight, and as soon as the window of the study is opened, the moonlight can just shine on the bookcase, and if you light the oil lamp, you can see it more clearly.

In the past few days, in addition to giving lectures and practicing calligraphy to students, he has time to read some articles from the township examination and the general examination.

I'm a literati, and I can still write the basic eight-strand text, but it's not easy to improve it. Although there is a library in my head, there are all kinds of ancient and modern Chinese and foreign literature, and there are countless Bagu texts, but it is still necessary to improve myself.

If he didn't study and improve, Lu Cheng was very worried that one day the library in his head would suddenly disappear, and he would really become a useless scholar.

In fact, Lu Cheng can turn over a lot of modern recipes in his mind, such as soap, glass, telescopes, etc. The point is that in this day and age, it is too difficult to find all kinds of materials.

Many of the chemical components of later generations, of course, may have substitutes in this era, but he has not had time to think about it in depth. There is another one, some materials are too scarce to buy, not to mention, the price will not be low.

Lu Cheng found that the time-traveling novels he had read before were tossed around in ancient times, and it was indeed unrealistic to be able to come up with something modern at will.

Now that I have the recipes for various processes, don't I have no clue what to invent?

However, it is not impossible to say that it can be built in a short period of time. For example, the simplest soap, if you take a little time to think about it, you can really make it.

To make handmade soap, the things you need are also very simple, and there are only three things to simplify: vegetable oil and water, and sodium hydroxide.

Ready-made sodium hydroxide, of course, is not available in this era, but Lu Cheng's slag's chemistry still plays a role here.

Sodium hydroxide can be made from hydrated lime and soda ash, and quicklime can be turned into mature lime by adding water. As for soda ash, it is not too pure at this time, and it is basically used to refine alkali from plant ash, which should be temporarily used as a substitute.

However, Lu Cheng is a literati, and the most important thing now is to gain fame and become an official in the court.

In more time, he is reading some Cheng Wen, learning how to solve problems, how to quote scriptures and classics to write a good article. As for the invention, he won't pay too much attention to it at the moment, and he will try to play again when he has time, and he can achieve it, and if he can't, forget it.

At the beginning, Lu Cheng thought that he could be an inventor in the Ming Dynasty and make a fortune through some modern things.

Later, I thought about it, I now have a private school, and my family is quite passable, and next year is the year of the township examination, and the imperial examination is the right way.

In the future, if this road really doesn't work, it's not too late to think of another way out.

Officials, businessmen, officials, and businessmen, in this era, if you don't have an official body, no matter how much money you make, it's useless. The court or the government, it's not a matter of one sentence to want to hack you?

Shen Wansan, the richest businessman in the early Ming Dynasty, was the real rich man of the Ming Dynasty, who was once rich enough to rival the country! In the end, it wasn't because he angered Zhu Yuanzhang that he was confiscated from his family property and sent to the Yunnan border?

Of course, it is impossible for a person like Shen Wansan not to collude and bribe some local officials, just because he offended the Son of Heaven, he would end up like this. It's just that Zhu Yuanzhang is jealous of his family property, who can say clearly?

In this era of clear classes, it is more promising to be an official, and businessmen are the lives of officials and masters.

Three years of Qing Governor's Mansion, 100,000 snowflakes of silver.

The official is sitting in the yamen, and you have to send money to people. As a businessman, you must deal with the people on the official face, if you don't have this awareness, do you still want to continue to make money?

Lu Cheng practiced calligraphy for a while, and suddenly remembered that when Shen Yi was leaving, he had given him a fan, but he hadn't taken it out and used it yet. At that moment, he took out the fan, and wrote a poem on the back of the pen. As for the positive, he thought about it and finally wrote down only the word "sincerity".

"Wei Shu Wu, fighting for the Han Dynasty, the Three Kingdoms, up to the two Jins. Song Qiji, Liang Chencheng, for the Southern Dynasty, the capital of Jinling. ”

In class, Lu Cheng read the scriptures he was going to learn this morning, and then began to explain: "We just learned yesterday, the two Han Dynasty for more than 400 years, and finally presented the emperor. Today, what we learn is the next Three Kingdoms period. Do any of you know the story of the Three Kingdoms? ”

The disciples sitting below shook their heads when they heard this, they had just entered the school, even if there was already "Romance of the Three Kingdoms" circulating in the world at this time, even if someone had it at home, but in the case of not being literate, they would not be able to understand it.

Lu Cheng has now changed his teaching method and pays attention to entertaining, so he plans to tell the story of the Three Kingdoms briefly. However, he is talking about the "genuine" history of the Three Kingdoms, not romance.

Romance, for the sake of storytelling, is inconsistent with history in some places, and will mislead these children.

Lu Cheng is still very talented in storytelling, and after a brief review of history, he skillfully cut into the "Yellow Turban Rebellion" and told the story of the Three Kingdoms for hegemony vividly. If you're not careful, it takes a little more time.

He stopped in time in the most wonderful place, and the next few words were brought over, making a bunch of children itch.

"Master, why did you finish it so quickly?" Some disciples raised questions.

"Now is the time to study, and if you want to hear the story, let's finish today's scriptures."

Lu Cheng said with a smile. What he wants is such an effect, as long as it can mobilize the motivation of these children to learn, is he afraid that they will learn slowly?

Sure enough, under the temptation of Lu Cheng, the time it took for the students to memorize the scriptures was even shorter today.

No way, who made them all anxious to hear the story?

"Master, we've all learned, can we tell stories?" A disciple asked aloud.

"Well, I'll have to test you."

Lu Cheng smiled lightly: "Zhou Kangping, you first recite the scriptures." ”

"Yes, Master."

Zhou Kangping was named, immediately got up and saluted, and recited with his mouth: "Wei Shu Wu, fight for the Han Dynasty, the Three Kingdoms, and the two Jins." Song Qiji, Liang Chencheng, for the Southern Dynasty, the capital of Jinling. ”

"What, then, is this text talking about?" Lu Cheng asked.

"Master, this scripture is about the end of the Eastern Han Dynasty, when the three kingdoms of Wei, Shu, and Wu competed for the world, showing a three-legged trend. After that, Cao Wei destroyed the Shu and Wu kingdoms, but was eventually usurped by Sima Yi to the throne......"

After he finished answering, Lu Cheng nodded with satisfaction, asked him to sit down, and then nodded to another student.

After drawing a few people, he was able to confirm that the children had indeed learned this paragraph.

Next, it was time for Lu Cheng to tell the story, but he stated in advance that he was telling the story of the hero in the script, and some things were made up.

In fact, many people in this era will also go to tea shops to listen to people's stories, and it is often easy to confuse romance with official history. Lu Cheng first used the official history as a foreshadowing, and then explained the distinction in advance, so that he didn't have to worry about the disciples not being able to distinguish clearly.
