I am Wu Dalang, starting with Pan Jinlian

In one morning, Wu Fei sorted out the mathematics textbooks for elementary school grades one to five. As for the junior high school textbooks, he hasn't got them out yet, let alone physics and chemistry textbooks.

He stood up, picked up the math textbooks he had arranged, and prepared to go to the old courtyard, and handed these to the teacher Chen Ziang first, so as not to delay it any longer.

After seeing Chen Ziang, Wu Fei handed over the mathematics textbook.

Chen Ziang rolled his eyes. This time, more than ten days have passed since the promised time.

This made Wu Fei feel a little embarrassed, even though he was Chen Ziang's benefactor.

Chen Ziang didn't speak, he took the math textbook and started flipping through it.

Looking at it, he was immersed in the world of mathematics.

He never knew that mathematics could be so charming. Unlike Confucianism, the contents of this textbook systematically explained mathematics from easy to difficult, showing the charm of mathematics.

If he hadn't encountered something he didn't understand, Chen Ziang probably wouldn't have woken up.

Seeing that Wu Fei was still waiting, Chen Ziang felt that he was being rude.

"Master Wu, why haven't you left yet?" Chen Ziang asked.

"Um, me"

Before Wu Fei finished speaking, he was interrupted by Chen Ziang.

"Stop talking, let me ask you a question, what does this mean?"

Chen Ziang pointed to a question in the mathematics textbook and asked.

Wu Fei went up to take a look, I went, it turned out that I was in a hurry and didn't have time to correct the case.

It reads: "From Xiao Ming's house to the school, one pole was installed every 50 meters, plus the two at both ends, a total of 55 poles, now it is changed to one pole every 60 meters, except for two poles. Apart from the two at the end that do not need to be moved, how many of them do not need to be moved in the middle?"

Wu Fei panicked, but the problem with the telegraph pole was fine, the key was that Chen Ziang didn't know what a telegraph pole was!

It seems that I have to continue to review it, otherwise, there must be other problems in this mathematics textbook.

So, Wu Fei said directly: "Oh, don't worry about this topic, it's beyond the outline!"

Chen Ziang stared.

Wu Fei quickly appeased and said: "Well, I'll go back and look at it again, and bring it back if there are no mistakes."

He knew that today's scholars are not fuel-efficient lamps, and they are all praised too highly by Zhao Kuangyin and Zhao Guangyi.

After snatching the textbook from Chen Ziang's hand, Wu Fei left in a hurry.

It seems that I have to work on this textbook again. There are really many nouns and words, and they can't understand it!
This problem will continue to exist for a long time. After all, Wu Fei has experienced the era of knowledge explosion, and people in Song Dynasty have never even heard of it, let alone seen it.

Wu Fei returned to his study and began to check the teaching materials from the beginning.

Before I watched much, I was interrupted by Wu An because there was a visitor!

Wu Fei asked Wu An to bring someone over, cleaned up the table a little, walked out of the study, and came to the living room.

After a while, Qin Ying walked in.

Wu Fei stood up and came to the door to greet Qin Ying.

"Brother Qin, what brought you here today?" Wu Fei asked with a smile.

Qin Ying clasped her fists and replied, "Master Wu is too polite, it's really hard to do!"

After a pause, Qin Ying continued: "His Royal Highness asked me to take you to the place where coal cakes are sold, and the trial operation will start today!"

Wu Fei had no choice but to respond, and followed Qin Ying to the place where coal cakes were sold.

When I got to the place, I saw that there were quite a lot of people around, but no one came forward to buy briquettes.

Wu Fei thought about it and understood.

It is estimated that these people do not know how to use briquettes, so they dare not buy them.

In order to reassure them, Wu Fei asked someone to find some bricks and some reconciled mud.

After the things arrived, he began to direct people to make a coal stove in the open space.

After it was done, without waiting for the coal stove to dry in the shade, Wu Fei couldn't wait to have someone light the briquettes with wood and put them in the coal stove.

Seeing the briquettes burning blazingly in the coal stove, Wu Fei felt a burst of excitement.

This, he can be considered to have changed Da Song!Thousands of years later, if relevant historical documents are unearthed, will he be clearly recorded because of this incident?

After driving this unreliable idea out of his mind, Wu Fei thought, since he is acting, he should do the whole thing.

So, Wu Fei ordered people to bring a big iron pot and some ingredients, and began to show everyone how to cook on a coal stove!
Seeing this, the crowd of onlookers not only did not decrease, but actually increased a lot more than before.

In the crowd watching, Wu Fei made a stir-fry.

After the pork was put in and the oil was fried, he added the vegetables to be fried.

In the process, he specially performed how to flip the spoon.

This unique skill immediately stunned the crowd and caused cheers one after another.

Seeing that his strategy was working, Wu Fei began to arrange a few people to introduce briquettes in turn.

Not to mention, this performance is quite effective, but it really attracted a few people to buy briquettes.

What Wu Fei didn't know was that with more and more briquettes, Prince Zhao Heng had already ordered the government to promote the sale of briquettes and control the sale of firewood!

This is why some people came to watch and buy coal cakes.

Seeing the still burning coal stove, Wu Fei realized that there is still a difference between an earthen stove and a coal stove.

If you want to use briquettes, you need to change the structure of the original soil stove, so that you can use briquettes more quickly, better and more economically.

So, Wu Fei called the buddies, pointed to the coal stove, and introduced to them some things that need to be paid attention to when building a coal stove.

After that, Wu Fei didn't bother to continue introducing briquettes here.

After explaining the matter, he got into the carriage and went back to Wufu.

After arriving home, Wu Fei went into the study again, and he wanted to continue sorting out the math textbooks.

Chen Yuanyuan walked in, poured a cup of tea, and went out again.

Wu Fei, on the other hand, continued to proofread.

After a quarter of an hour or so, Wu Fei stopped and drank some tea.

Chen Yuanyuan walked in again.

Wu Fei sniffed it vigorously, but he didn't smell the fragrance of toilet water.

"That's not right. A quarter of an hour ago, Chen Yuanyuan's body was still filled with fragrance!" Wu Fei thought to himself.

"Yuanyuan, during your time out, did you wash your hands or face? Or did you change your clothes?"

"Returning to the master, I have never done these things!"

"Okay, I know!"

Wu Fei fell into deep thought.

Doesn't the scent of toilet water last long?
Wu Fei decided to try again, he asked Chen Yuanyuan to go back and spray some toilet water, and walked back.

After smelling the fragrance of Chen Yuanyuan's body, Wu Fei recorded it, and then asked Chen Yuanyuan to go to the courtyard and come in after a quarter of an hour.

Soon the time was up, and Chen Yuanyuan walked in again.

As soon as Wu Fei smelled it, he immediately understood that the scent of toilet water really doesn't last long!
