Gao Li found that he really underestimated this Niu Dun'er child.

From the first day of class with Gao Li, this Niu Duner child has been fascinated by mathematics. What's even more amazing is that his acceptance of numbers far exceeds Gao Li's imagination, how to describe it?

To put it simply, some concepts and concepts of all the numerical mathematics described by Gao Li, as long as the children of Niudun listen to it and read it again, they can basically understand it, even if there are some difficult contents, Gao Li gave him two questions, and after a live demonstration, he will understand.

This kid is simply a natural mathematician!

While other children are still learning addition and subtraction, they are already able to understand multiplication and division. By the time other kids start learning multiplication and division, they can square manually.

At this time, the child was only 7 years old, and at this rate, Gao Li suspected that by the time he was 10 years old, he would basically be able to play calculus to 66.

Math is just one of Gao Li's courses, and for these children, Gao Li also has another course called science class, which is also a primary school course. The so-called science is naturally to understand the world through exploration and practice, and Gao Li provides them with a new way of thinking about the world.

Why do birds fly, why do fish swim in water, why are leaves green, how do rainbows appear?

Someone must have thought about these questions, but certainly no one has been able to figure them out yet. For example, the appearance of the rainbow, after Gao Li explained some basic principles, he taught the children the simplest way to play, take a sip of water, turn your back to the sun, and then squirt out, the finer the water mist, the more obvious the rainbow.

For a while, the children went crazy, and the parents found Gao Li and told him that the children didn't know what hysteria they had, and when they got home, they desperately sprayed water to show their families.

Gao Li could only comfort them, telling him that this was just a game that the children were playing, and that there was no need to worry, so he sent away the skeptical parents.

Ling Long looked at Gao Li, teaching mathematics and science, and felt that he only taught one subject of reading, which seemed too simple. So he found Gao Li and asked if he could teach anything more. Gao Li estimated that Ling Long was a very serious liberal arts student, since this was the case, why not let her try to teach history?

However, problems arise.

If you want to teach history, you must first know history. There doesn't seem to be a library in this world that teaches history, and I've never even heard of any decent history books. For this reason, Gao Li went to Qixiu Academy to check it out, and found that the history that can be consulted at present is only three hundred years. And three hundred years is the age of the Wu Dynasty.

What's going on?

Given the prosperity of this world, a thousand years is certainly not enough. What can be done in 300 years?

Where did the history of 300 years go away?

To be able to erase history, this will inevitably use the power of the whole country, human forgetfulness is very large, word of mouth is quite inaccurate, some things spread too much, it becomes a myth. Therefore, at this time, historians are needed to write history books, which may be too subjective, but they are still generally accurate. But the history books that can be found now are only related to the Wu Kingdom. No one knows about the history books outside of the Wu Kingdom.

Could it be ...... Is this a dusty piece of black history?

For this reason, Gao Li went to find Chu Miaoyi, this little princess has liked to soak in the royal library since she was a child, and the types of books she read are quite mixed, and she may be able to get some clues.

When Chu Miaoyi heard Gao Li's question, his first reaction was to widen his eyes, and his face was full of surprise: "There is such a thing?"

Great, she didn't know.

It turns out that although Chu Miaoyi likes to read, most of the books she reads have nothing to do with history, and most of them are 'miscellaneous books' that record all kinds of strange events and various inventions of Gewusi.

"I have only one question. Gao Li asked. "Before the Martial Kingdom, what was this place?"

Hearing this question, Chu Miaoyi immediately shook his head.

"I never thought about it!"

Gao Li has never thought about the history of this world, and the history that most people care about will definitely not exceed fifty years before and after. Back then, the two Spring and Autumn envoys of the Spring and Autumn Tower once said that their Spring and Autumn Tower recorded history. Wild History, 3,000 years, Literary History, 1,000 years, and Letter History, 500 years. At that time, Gao Li was completely dismissive, because in his opinion, such a thing as history was not very great information. But now it seems that the situation is far more complicated than he thought.

"You say, is there a historical record in the royal library?" asked Gao Li.

"Yes...... Right?" Chu Miaoyi actually asked Gao Li, she didn't seem to have much confidence.

When Gao Li told Ling Long about this, Ling Long had an incredible expression on his face.

"How can this be?" Ling Long said.

Gao Li didn't have a good way to deal with this matter, so he couldn't ask Chu Miaoyi to go back to the palace because of this matter that was not really urgent, right?

"I want to go to the Royal Library. Ling Long said.

"When?"

"Now. ”

After a period of contact, Gao Li was already very sure that Ling Long was actually a very impatient person, and he didn't have much patience for many things. Gao Li guessed that this was related to his too smooth sailing cultivation progress, after all, according to Gao Li's understanding of Ling Long, this girl had not encountered any bottlenecks and problems since the beginning of her cultivation.

"That's ...... It's good. "The legendary Yannan King's rebellion is still far away, since Ling Long is interested in this matter, then let him go and take a look.

"I'll go with you?" Gao Li's mind was full of the romantic two-person world on the road.

"This ...... It's okay......" Although Ling Long said that it was okay, her expression told Gao Li that she was actually very embarrassed.

Thinking about it, with Ling Long's current cultivation, it could go straight to Shangjing at an almost flying speed, and after checking the information she wanted, it could easily fly back. can take Gao Li, although the little donkey cart is really punk, extremely romantic, but the speed is too slow.

"Haha, I'm kidding, you go by yourself, go and come back quickly, pay attention to safety. "Gao Li Dao.

"Hmm. Ling Long nodded very solemnly, cleaned up a little, and immediately left Li Zhuang.

Hey, at present, it is still difficult to become a peerless master, why not invent a motorcycle first?

Since the senior decided to establish Li Zhuang's private army, the entire Li Zhuang has become lively, after all, combat training always has to be noisy, and the combat effectiveness of these demon clans in Li Zhuang is not weak, listening to the sound of metal clanging every day, it is also lively, of course, Gao Li's only concern is their marksmanship.

The spider monsters have six arms and six eyes, which brings them great convenience, they can control three guns at the same time, Gao Li doesn't have that many eyes, he doesn't know what it's like to control three guns at the same time, but at least it seems, the spider monsters are really cool.

The bull demons are tall and big, and the Winchester series made by Gao Li is like a toy in their hands, so Gao Li customized a new enlarged version of Winchester for them. Thickened barrels, thickened and lengthened bullets, and higher charges. With the help of precision processing by male spiders and 3D printed gold-eating ants, these firearms were mass-produced.

The fun of firearm shooting is difficult for people who have never played it to understand, and once they have played it, they can never put it down. The entire Lizhuang was filled with the thump of gunfire at any time, and there was no shortage of iron or spider silk in Lizhuang. Gao Li knows that all excellent fighters are fed with bullets, so the bullets are enough!

Gao Li's plan is that all the people are soldiers, all adults in Lizhuang must be militarized, and everyone will be issued with weapons, only in this way can the property of Lizhuang be protected to the maximum.

Of course, although Gao Li was actively preparing, he always thought that even if King Yannan really rebelled, it would be impossible to threaten Pingyang City.

However, things turned out much more than he expected.

On the second day after Ling Long left Li Zhuang, the king of Yannan unveiled the rod in Yannan City, and what was even more amazing was that Yannan City went north to the two big cities, and surrendered almost immediately.

In other words, at this time, there is no big city in front of Pingyang City!

At this moment, Gao Li understood why Li Tiequan was so worried about himself at that time, it turned out that the two cities were either falling with the wind, or they had already agreed with King Yannan. In this way, the king of Yannan went north with the Yanan army and went straight to Pingyang City!
