Early the next morning, Zhao Feng walked out of the door in good spirits, and in the room, only the lazy four girls were left sleeping soundly on the bed.

"One...... ......As soon as he came to the courtyard, Zhao Feng heard an immature voice shouting the password. When I walked in, it turned out to be Zhao Yi who was doing morning exercises.

"Yi'er!" Zhao Feng shouted.

"Daddy!" When Zhao Yi saw Zhao Feng, he immediately stopped his movements and ran towards Zhao Feng quickly.

"Hehe, does Yi'er miss her father?" Zhao Feng hugged Xiao Zhao Yi up, and instantly felt a sense of blood connection.

"Thought!" Zhao Yi, who is four and a half years old, said in a milky voice.

"Hehe, is Yi'er well-behaved at home these days?" Zhao Feng asked.

"Of course, I know what my grandfather taught me! Also, Master Taishi taught me a set of boxing techniques, Daddy, Yi'er will call you, okay? Zhao Yi said.

"Okay! Then Yi'er can call me. Saying that, Zhao Feng put Xiao Zhao Yi on the ground.

"Hee-hee, daddy is optimistic!" With that, Xiao Zhao Yi shook his fist one by one.

Looking at Zhao Yi's serious appearance, Zhao Feng smiled, although Zhao Yi's actions at the moment were not standard, but he was doing his best to show his father the best he had played.

"Good!" Zhao Feng applauded without hesitation.

"Hee-hee!" Zhao Yi looked at Zhao Feng with a grin.

"Go wash your face, it's all a little cat, and go to eat after washing." Zhao Feng smiled and turned to leave.

"Yi'er, what did your grandfather teach you?" While eating, Zhao Feng asked.

"Teach me the Four Books and the Five Classics, as well as some basic knowledge of arithmetic." Zhao Yi thought for a while.

"Then how much have you learned in the Four Books and Five Classics?" Zhao Feng asked again. Only then did he remember that at this time in the late Han Dynasty, it seemed that there was really no decent enlightenment book for early childhood education, and he was really careless and forgot such an important thing.

"Uh...... This one can only be recited simply, and there are many words that Yi'er doesn't understand what it means. Zhao Yi said hesitantly, secretly observing Zhao Feng's expression as he spoke.

"Hehe, this is also difficult for you, in this way, Daddy will compile a few enlightenment textbooks for you after dinner, you don't need to read any Four Books and Five Classics, the Four Books and Five Classics will be read when you are older and your understanding is stronger." Zhao Fengdao.

"Daddy wants to make a book?" Xiao Zhao Yi looked at this Zhao Feng in disbelief.

"yes, what? Don't believe Daddy? Zhao Feng smiled and scratched Zhao Yi's little nose.

"I don't believe it." Zhao Yi shook his head honestly.

"Hehe, wait for Daddy to let you see it!" Zhao Feng smiled helplessly, he had failed too much, and his son didn't even believe in himself.

"Oh!" Zhao Yi nodded suspiciously.

After the meal, Zhao Feng plunged into the study, and wrote out the "Three Character Classic", "Hundred Family Names", "Thousand Character Text", and "Disciple Rules", of course, the allusions that have not yet been adapted by Zhao Feng meaning, and also according to the primary school mathematics textbooks of later generations, compiled an enlightenment book on arithmetic, in addition, Zhao Feng also compiled Chinese Pinyin into a book.

"Father-in-law, Mr. Kang Cheng, these are the six books I have compiled, which can be regarded as an enlightenment book for children before the age of eight." Zhao Feng handed the six books he had "compiled" to Zheng Xuan and Cai Yong.

"This is ......" Zheng Xuan picked up the book of "Hundred Family Names" and flipped through it, "Zhao Qian, Sun Li, Zhou Wu, Zheng Wang, Feng Chen, Chuwei, Jiang Shen, Han Yang...... Okay, okay, although it's just a surname, it's catchy, and it's really a good article for teaching children to read! ”

"That's good! At the beginning of people, their nature is good, their sex is similar, and their habits are far away...... Easy-to-understand education for kids! Hehe, you see, Kong Rong's kid made the story of pears all written in! Cai Yong was full of praise for the "Three Character Classic".

"Oh? Let me see, it's really, Rong is four years old, can make pears, younger brother Yu Chang, Yi prophet! It's really good, the content of the article is easy to understand, and so is the reasoning in it, which is really a masterpiece! Zheng Xuan praised.

"What is this?" Cai Yong picked up the book "The Complete Explanation of Chinese Pinyin" and asked.

"Father-in-law, this is a kind of annotation that I have researched to facilitate children's literacy, and I named him Hanyu Pinyin!" Zhao Feng said shamelessly.

"Hanyu Pinyin? Let me see, huh? It seems that there are only a few sounds in Chinese characters! Cai Yong thought back in his mind.

"Absolutely! Uncle, once this thing is promoted, it will be much easier for us to teach students! Zheng Xuan said.

"Well, yes, I want to promote this thing to our Eastern Liaoning Academy as soon as possible!" Cai Yong said.

"Father-in-law, don't worry, there is still this book!" As he spoke, Zhao Feng handed the simple "Elementary Mathematics" to Cai Yong.

"Huh? Let me see, math? Isn't it just counting? Cai Yong looked through the pages one by one, "What do these symbols mean?" ”

"Oh yes, I forgot to explain, I think it's too troublesome to write numbers now, so I invented a set of numbers myself, which is introduced at the front of the book, father-in-law, you see, there are also this symbols of addition, subtraction, multiplication and division." Zhao Feng explained one by one.

"It's really good, so look at it, the numbers are much clearer, if those accounts are using this number to keep accounts, it will greatly reduce the embarrassing situation of misremembering!" Zheng Xuan was the first to speak.

"I won't look at this thing, Brother Kang Cheng will tell me after studying it!" Cai Yong didn't like mathematics after all, so he still held the "Three Character Classic" and read it.

"Mr. Kang Cheng, father-in-law, I want to use these books as enlightenment books to teach Yi'er first, if it is effective for Yi'er, then I will promote this book, what do you think?" Zhao Fengdao.

"Well, yes, let's use this book to teach Yi'er next!" Zheng Xuan thought about it and nodded.

"You don't have to try to succeed!" Cai Yong asserted.

"Hehe, I'm going to trouble the two gentlemen next!" Zhao Feng bowed to the two.

"It's easy to say, you go back, we still have to read books!" Cai Yong waved his hand directly, and blasted Zhao Feng away without raising his head.

"......" Zhao Feng was speechless, and he began to wonder if he was right or wrong to give these books to Zheng Xuan and Cai Yong.

"Enlightened lord, there is a guest visiting." Before Zhao Feng went out, someone came to report.

"Guest? Who is it? Zhao Feng asked suspiciously.

"I don't know, that person only said that he was from Yanzhou."

"Okay, got it!" Zhao Feng patted his head, "It seems that it is going to be good!" ”

Yanzhou? You don't have to think about it to know that Cao Cao sent someone! Zhao Feng hadn't figured out why Cao Cao had to marry him before, but now it seems that he has touched some eyebrows, Cao Cao's power is new, it seems that he lacks everything, right?

Thinking about it, Zhao Feng still walked quickly towards the Taishou Mansion.
