Since the last time I gave a special lesson to the students of the academy.

Xiao Han, who had nothing to do, seemed to have found a new toy, and ran to destroy people every once in a while...... No! It's a tireless addiction.

It's just that his style of class is too bold, so that he often plays cards unreasonably, and when he thinks of it, it's a play!

This point is quite criticized by Mr. College.

If it weren't for his deep foundation in arithmetic, what he said would indeed make sense!

It is estimated that he has been pulled by the legs of a group of gentlemen and thrown out of the academy from the wall a long time ago!

Oh, and when it came to throwing out of the academy, I almost forgot one more thing.

is the middle-aged teacher who lost face because of arguing with Xiao Han.

After that day, he didn't quit the academy as wittily as Xiao Han thought, but still stayed here with a cheeky face.

However, this time he has learned to be obedient thoroughly, and he tries not to meet Xiao Han in the academy.

Occasionally, he encountered it, but he also avoided it, so that Xiao Han couldn't find fault if he wanted to, so he could only pretend to be generous, but in fact, he was stupid.

————

In today's colleges, students should be asked whose classes they love the most?

Among the ten people, it is estimated that ten and a half answers are Xiao Yuan's sentences!

Such a support rate that even the favorite of the student party in the past, the physical education teacher! looked at Xiao Han's eyes with a little resentment......

It hurt Xiao Han to think that this muscular guy had some special hobby that couldn't be explained, and when he saw it once, he palpitated once.

The most popular among students, the most popular course of the Siu Academy, is characterized by its eclecticism, even in the College.

If someone sees a large group of children in the field studying weeds, rice fields, or even stones.

There is no doubt that this must be the team led by Xiao Han!

Discovering from practice and learning from discovery is Xiao Han's special education method, and he has achieved remarkable results.

After seeing the windmills in the countryside and the watermills by the river, some students had a big brainstorm and wanted to connect the windmill with the waterwheel and make a machine that used wind power to replace manpower to draw water.

In this way, the keel waterwheel can be driven by a steady stream of wind, and those farmers don't have to step on the waterwheel, and the legs are about to break.

Excitedly told the court about this idea.

The court didn't say anything, just gave them a few pieces of money to make a small model in their spare time.

Holding a few pieces of money, several students cheered!

This is the first investment they have ever made, and even students from very privileged families feel that this money is extraordinarily weighty!

With money, the students unanimously decided that the money should not be spent indiscriminately, and every penny must be used to the best of their ability.

To make models of wood, they can go to the woods and cut them.

As for carving and molding, you can also let a carpenter's handicraft master do it for you.

Only when they can't get out of the transmission, hook, bearing and other devices, they will carefully take out the money and buy it outside.

Then again, can a windmill drive a waterwheel?

Naturally!

But does it make sense?

The answer Xiao Han is also very clear: there is no point!

If he wanted to do it without lifting water, he had at least several ways to do it, but none of them were achieved by a large bulky windmill.

However, in the face of the failures of these students again and again, he still readily increased his investment.

Research is like that, even if the result is doomed, then the process is a different kind of reward!

Didn't you see that those children have transformed the waterwheel to be more convenient and lighter than before in order to allow the windmill to pull the heavy keel waterwheel? That in itself, is a bonus!

The project of the wind turbine took about a month, and as expected, it failed!

The materials do not meet the requirements, and the kinetic energy loss of the windmill is serious, these are all big problems that students can't solve!

Such a thing, even if it is made, even if it barely drives the waterwheel, it is easily damaged and has no practical value!

However, although the wind-powered waterwheel failed, the new waterwheel they transformed made Xiao Han smile from ear to ear.

As an investor, I took out the new waterwheel model and sold it to a businessman who sold farm tools, not only earning back the ten or so yuan of the investment, but also leaving a few pieces of money, which was enough to invite a few students to a big meal!

At the beginning, Yin Can was very disdainful of Xiao Han's behavior, thinking that he was purely misleading people's children!

However, after watching it for a long time and figuring out the taste, he no longer objected, and even occasionally followed his example and pulled the students out to let them fly.

The Mo family has been entrenched in Yangzhou City for a hundred years, and the places they can go to and the scenes they can see are naturally much more than Xiao Han, who is unfamiliar with the place!

No, I occasionally went to a book printing workshop, and when I came back, Wang Chongan gave him a big surprise.

"Judgment of the Yin Court, if you give me ten yuan of money, I will tell you a way to speed up the printing of books!"

After returning from the book printing workshop, the little fat man Wang Chongan sneaked into Yin Can's office and said mysteriously.

"Pop ......" With a crisp sound, a ten-run treasure bill slapped on the table in front of him.

Speaking of which, today's treasure banknotes are no longer simply pieces of paper jointly issued by several commercial banks.

It has now been endorsed by the government and remade with a lot of official coins with anti-counterfeiting marks!

Although at present, only a few places in Yangzhou and Hangzhou recognize this kind of treasure banknote......

"Don't look at it, it's true! There can't be this kind of wick paper out there! ”

I really can't get used to seeing the little fat man looking east and west with the treasure money, and he is afraid that he will deceive him, Yin Can gritted his teeth and scolded angrily, and at the same time decided: If this guy can't say one, two, three, four, then he must let this little guy know what is called the majesty of the court judgment!!

"Hehe...... the little fat man Wang Chongan was frightened by Yin Can, but he quickly grinned.

While laughing, he carefully folded the treasure money and put it in his arms.

When it was about to leave, it patted it disgustingly, as if it was afraid that it would run away with long legs.

When Yin Can saw his movements, his brows suddenly wrinkled deeper: "The money has been collected, let's talk about it!" If I don't think it's good, even if you swallow it, I have a way to make you spit it out again! ”

"Hey, just ten times of money can only benefit yourself, not even your family, let alone benefit the world! I wouldn't be so stupid to swallow it! ”

Wang Chongan rolled his eyes, shook his head and was just halfway through speaking, when he suddenly felt that something was not quite right, why was the air around him a little cold?

"Ahem...... I mean, the printing workshop we saw in the morning was too slow to pick up words! When you look for a word, sometimes you have to find it for a long time! It's hard to look at, so I figured out a new thing that can arrange all the words in order on it, so that the speed of picking up words is faster? ”
