Emperor Ling is a little funny, how old is this Liu Bei, he should be three or four years younger than him, so young, he knows the relationship between clinging to the imperial power. What a talent!

Therefore, he said: "This matter is too far, but the imperial brother does not dare to do it." ”

Lu Zhi listened and found that Emperor Ling didn't like this apprentice named Liu Bei. Therefore, he said: "Your Majesty, this Liu Bei has a tenacious temperament and a strong will, although he is only twelve years old now, he should be a rare talent in the future. ”

"Since it is a talent, then send Liu Bei to Taixue for cultivation first." The Spirit Emperor said undeniably.

When Lu Zhi heard this, he felt that Emperor Ling sometimes did things so inexplicably, and suddenly he came up with a strange idea, and even racked his brains, he couldn't figure out why he did it.

For example, a few words will send Liu Bei to Taixue. Lu Zhi was very depressed, and had to send Xiao Liu Bei to Taixue for cultivation and not mention it for the time being.

Emperor Liu Hong returned to the palace and couldn't help but ponder. Nowadays, with the advent of new papermaking methods, the paper in Luodu is cheaper. Families with spare money began to send their children to school.

With cheap paper, it's time for important printing techniques to begin.

The "Mathematics" of elementary, junior high, and high school in Emperor Ling's mind, as well as "Physics" and "Simple Chemistry", all had to be printed.

Emperor Ling called a small yellow door and informed Liu Na to see him.

After a while, Liu Na arrived. When Emperor Ling saw Liu Na, he asked, "Liu Aiqing, I now need 100 craftsmen who can engrave, how long will it take to find them?" ”

Liu Na said: "Your Majesty, there are not many craftsmen who can carve seals now, and if you want to find 100 of them, it will take at least three days." ”

Emperor Ling said, "Give you five days to find all the craftsmen." ”

Liu Na took the order and left.

Then he ordered someone to call Cai Yong and Cai Zhonglang, and when Cai Yong arrived, it was almost late at night.

Emperor Ling called a few imperial chefs, killed a few chickens, took all the chicken wings and chicken legs, slapped them loose with the back of a knife, put on a few long bamboo sticks, sprinkled some salt, and then burned a large charcoal fire on the ground to roast the chicken wings and chicken legs.

Cai Yong stood there at a loss, the so-called gentleman was far away from cooking, but he was surprised to find that Emperor Ling would still eat it, but he didn't know what this food would become under his barbecue.

Suddenly, a burst of fragrance wafted out, and Emperor Ling beckoned Cai Yong to sit on the side, constantly flipping the chicken wings. Then he took out a little honey from a crockpot on the side and smeared it on the chicken wings, and after a while, the chicken wings became more fragrant, and Cai Yong involuntarily swallowed a mouthful of saliva.

"Hungry, aren't you?" As he spoke, Emperor Ling took out two from above, handed one to Cai Yong, took one himself, and ate it while it was hot.

Cai Yong smiled, no matter what kind of trick he is, let's eat it first, anyway, the emperor has eaten it, and he can't eat the dead. Thinking about it, he took a bite of a chicken wing and chewed it.

The chicken wings dissipated in the mouth, and a characteristic umami spread in the mouth. Cai Yong's eyes were wide open, completely attracted by the taste of this chicken wing. It's the first time I've grown so big and eaten such a delicious taste!

His taste buds were completely stimulated, completely ignoring the image of a generation of great writers, Sven landed and chewed on.

"Your Majesty, why are your grilled chicken wings so delicious!" Cai Yong ate three skewers in a row before he asked unsatisfied.

"I have a secret recipe in hand, how about using it to open a small barbecue restaurant among the people?" The Spirit Emperor laughed.

Cai Yong swallowed his saliva and said, "I will definitely go there often!" ”

"Hahaha......" Emperor Ling and Cai Yong glanced at each other, and both of them laughed.

"I'm done eating, Cai Aiqing, I have an important thing for you to do." As he spoke, Emperor Ling took out a stack of papers from a small cabinet, only to see that the paper was full of small characters.

Cai Yong took it and looked at it carefully.

Looking at it, Cai Yong frowned slowly, and after reading a few pages, he couldn't understand it anymore.

"Your Majesty, what kind of book is this? Weichen couldn't understand it. ”

"Cai Aiqing, it doesn't matter if you can't read it, I will explain to you, these words are called Arabic numerals, which represent from zero to pick, this is the four operation symbols of addition, subtraction, multiplication, and division, as long as you remember these, through your ability, it will not be difficult to understand."

After figuring out this, Cai Yong slowly understood. But later, when I saw the perimeter and area of the geometric figure, I could no longer understand it. Had to put down the book.

"Your Majesty, where did these Heavenly Books come from?" Cai Yong asked.

"These are just a few books of calculations about mathematics, not a book of heaven. Moreover, it was written over a dozen nights by me, and was specially designed to teach those who loved arithmetic and those who were in business. Emperor Ling said.

Cai Yong immediately grasped the crux of the problem and asked: "Your Majesty, if I am the only one to copy this book, I can copy it in three days, how can it be popularized to people who love arithmetic and those who do business?" ”

Emperor Ling nodded heavily and said, "Cai Aiqing really deserves to be a literary master, and he immediately grasped the key point of the matter. ”

Emperor Ling paused for a moment, then gently rubbed his temples, the night was already very dark, "Cai Aiqing, let's stay in the palace tonight." Tomorrow, the results will be in. ”

......

The Royal Palace in the early hours of the morning.

Emperor Ling got up early again as usual, only this time, he was carrying a double-strap backpack sewn by a servant girl on his shoulder, which was filled with quaint green bricks.

This generation of green bricks will be placed in later generations, maybe they will be cultural relics. Emperor Ling thought about it, but started running. The black-clothed guards acted collectively and no longer followed the Spirit Emperor.

The guards looked at the Spirit Emperor from a distance carrying a very strange burden, and thought to themselves, what kind of method did the emperor come up with, and he must learn it.

Cai Yong was shocked.

The 14-year-old emperor actually carried a bag of green bricks weighing about 100 catties, and ran for 10 miles without blushing or panting. What kind of emperor is this, but he who is familiar with the scriptures and history can't see through it at all?

It wasn't until breakfast that Liu Na brought 16 carvers to the palace to face the saint.

Emperor Ling then gathered the 16 craftsmen to the side and took out a drawing to explain that seals of the same size should be made according to the prescribed size. The words of each seal must be copied in accordance with Cai Zhonglang's handwriting.

Subsequently, Emperor Ling took out the "Book of Heaven" that he showed Cai Yong last night - "Primary School Mathematics", and asked Cai Yong to copy a new copy and carve it for 16 skilled craftsmen.

Then make a rectangular box slightly smaller than the A4 paper, and arrange the engraved stamps as they look on the first page of Elementary Mathematics. Then brush with thick ink, press on the paper, and in the next second, a neat page of words will be printed.

Cai Yong took this piece of paper incredulously and looked at it carefully, it seemed to be the words Cai Yong had just written, exactly the same.

With a cup of tea, more than 50 pages of these words have been printed.

Cai Yong was dumbfounded, and once remembered that when he was a child reading "Historical Records", he specially borrowed the book home and copied it for nearly two months before he finished copying it. It cost nearly 15 taels of silver.

And this method of printing books invented by the emperor, if these printing words are engraved, it is estimated that it will only take one day to print 100 copies of a book. The cost of a book is only a penny (100 yuan), and ordinary people can afford to buy books!

"Cai Zhonglang, Cai Zhonglang?"

Cai Yong was suddenly awakened by Emperor Ling's shout, and hurriedly said: "Your Majesty, Weichen deserves to die for his crimes, and he is distracted." ”

Emperor Ling smiled in his heart, if you don't get distracted, then you won't be Cai Da Wenhao, the purpose of calling you over this time is to let you wander and let you lose your soul.

But he said, "It's okay." Cai Zhonglang, if this matter is handed over to you, what should you do? ”

Cai Yong looked at the blue sky with his eyes, his deep eyes seemed to see through the universe, and he muttered: "Your Majesty, this you invented can make ordinary people in the Han Dynasty affordable to buy books, and increase the number of people in the world by ten times!" Your Majesty, you can become the first emperor of the ages with just this one thing, and all the scholars in the world will worship your god! ”

Cai Yong was so excited that he couldn't stop crying, "Your Majesty, if you leave this matter to me, I must print all the books in the world for everyone in the world to enjoy!" ”

"Nope! You're wrong! Emperor Ling decisively interrupted Cai Yong's words. I want to use this invention to promote the economy of the Han Dynasty, the culture of the Han Dynasty, the science and technology of the Han Dynasty, and finally promote the Han Dynasty to take a big step forward and unify the Central Plains of the world! ”
