"Father and Emperor even agreed to allow Samurai Tong to see the emperor's grandfather." Li Tai continued: "I know that my father wants to reward the warrior Tong, no matter what, the money he gave back then is a favor owed by the emperor's grandfather. ”

Gift? Talking to the emperor about favors? What are you kidding, you want Li Er to return the favor?

Unless he, Li Er, took the wrong medicine.

"What are you laughing at?"

Li Zheng said with a smile: "I think the most important thing in the world is to talk about favors with people like the emperor, and generally this kind of person will not end very well." ”

It is obviously inappropriate for Wu Shi Tong to talk to Li Shimin about Mount Tai Feng Zen at this juncture.

Now Li Shimin has just sat on the throne, and he has not achieved the achievements of previous dynasties.

If you want Mount Tai to seal Zen, you need enough merit.

Don't say whether Li Shimin has this ambition.

At least for the current Li Shimin, it is far from reaching the level where he can be sealed by Mount Tai.

Li Tai glanced at the village behind him and asked, "Why is Yan Liben in your village?" ”

"He's just here to help." Li Zheng said.

"Really?" Li Taiyou glanced back, "I saw that he brought a lot of luggage, I thought he was coming to live in your village for a long time." ”

Li Zheng cleared his throat and said, "How is the matter in Lingnan under His Royal Highness King Wei?" ”

Li Tai replied: "My father has already decided to appease Feng Ang first, but as you said, Zhenla and Nanzhao have that kind of rice seeds that are harvested twice a year?" ”

"The vicinity of the South China Sea is located in the subtropics, where the climate is very warm all year round, especially the closer you are to the South China Sea, it can be said that the four seasons are like spring, and there is no winter all year round."

"No winter all year round?"

"The climate determines the grain production, and if the Lingnan area is well managed, it is a huge granary."

Li Tai pondered Li Zheng's words, "It is recorded in the classics that there is abundant food in the area south of Lingnan.

Li Zheng continued: "The first emperor set up three counties in the South China Sea, the Han has Jiaozhi, and Lingnan has grain, but to make full use of it, if you want to make Lingnan the granary of the Central Plains, it is necessary to pacify Lingnan." ”

The pacification of Lingnan has always been a big problem, at least at the moment there are a lot of Tujia guest villages in Lingnan, civil strife has not stopped, and the territory of Nanzhao and Zhenla is ambiguous, and now Lingnan is a game of chess.

Li Zheng said to Li Tai again: "In a few days, your father will send officials to Lingnan." ”

"That's right." Li Tai nodded, "But the officials sent to Lingnan are in charge of the prince." ”

Li Zheng nodded slightly, "I see." ”

Li Tai still unconsciously glanced at Yan Liben, who was not far away, busy with a group of craftsmen.

I don't know why, but I always feel that something is wrong.

The next day, Yan Liben made Li Zhengyao's abacus.

"County marquis, how to use this abacus?"

Li Zheng took the abacus to take today's accounts, and after calculating them for a while, he came up with a surplus of accounts.

Yan Liben saw Li Zheng skillfully dialing the abacus, and he was dazzled for a while.

"Is this all out?"

"Well, there's a surplus of three thousand six hundred and seventy-five thousand." Li Zheng handed the account book to Yan Liben, "You also calculate?" ”

With so many accounts, Li Zheng can be clear in less than a moment.

Yan Liben was a little stunned, and waited for more than half an hour to calculate with his abacus.

"Well, right." Li Zheng said as he drank tea.

Yan Liben nodded vigorously, "This abacus is calculated so quickly?" ”

Can it not be fast? Card counting is one of the oldest arithmetic tools that can be handed down, and it has been used for a long time even in later generations.

Yan Li asked with interest: "County Marquis, how to use this abacus." ”

Li Zheng lifted the brush and wrote down the words under each line of abacus from right to left: "The abacus is divided into two lines, and the abacus below is full of five upper rows, and one column is full of ten, from right to left, one hundred thousand, one hundred thousand, depending on how much you want to count." ”

Yan Liben pondered this abacus carefully, "It's indeed much better than the abacus used today." ”

Li Zheng took out a book, "This is a textbook for the children in the village." ”

"Is this the kind of book that Jingyang students read?"

In fact, this is a book translated from a primary and secondary school physics textbook, and Li Zheng extracted some parts of the above content and changed it to Guan Chinese characters.

Yan Liben looked at the book and said, "What is gravity? Magnetic? Frictional force? ”

Li Zheng took the book back up, "Does Master Yan like this book?" ”

Yan Liben said with a difficult face: "I don't like it, but I really want to see it." ”

"There is scientific knowledge in this book, which is of great significance to craftsmen and craftsmen."

"The water pressure comes from this book?"

"Exactly." Li Zheng grinned and said, "It's not early, Master Yan should go and rest early." ”

Yan Liben left the horse ring in frustration, looked back at it, and was still a little reluctant to give up on the physics book in his heart.

I just glanced at the catalog, though I didn't know what the names said.

But looking at a name seems like something very mysterious.

Gravity?

Frictional force?

The textbooks for the children in Jingyang, Yan Liben immediately thought of the academy.

In the past, he only knew that Li Zheng had the ability, but knowing that Li Zheng's ability was written in the children's textbooks made Yan Liben sleepless all night.

Getting up in the middle of the night, Yan Liben walked out of his room.

The accommodation that Li Zheng arranged for himself was very good.

In addition to the sturdy houses, and the entrance is the Jingyang River.

Next door to his house live Li Yifu and Cheng Chumo.

As soon as he walked out of the house, he could hear Cheng Chu's silent snoring like thunder.

Walking further towards the academy, you can see that there are guards walking around in the village.

Yan Liben hurriedly retreated and returned to his room.

On the second day, the day dawned.

Li Yifu whispered beside Li Zheng: "County Marquis, this Yan Liben is weird. ”

"It's weird." Li Zheng said as he put the shell of a mud snail into a bowl of vinegar.

Li Yifu stood beside Li Zheng and whispered: "I don't say what is weird, it's just that this person is always walking around the academy, it seems that this person must have some plans for the academy." ”

"Really?"

Li Yifu said again: "The ability of the county marquis is to ask the university question, and the disciples of the county marquis can be forgotten, but if it can't be learned by others, unless it ......"

"Unless what?"

Li Yifu glanced at the direction of the academy again and said, "Unless he gives money!" ”

In addition to the children who are in class, there are also three guys who teach in the academy, Chu Suiliang, Shangguan Yi and Li Chunfeng, and there are children who are in class.

Ordinary people don't go to the academy to walk around, and the people in the village and the villagers all know that Li Zheng teaches the children skills.

Day and night, the village guards make regular rounds.

Li Ke usually stays outside the village, and now it is still a little difficult for strangers to enter Jingyang.
