Now that there is a way to rescue his father Yan Zhun without too much money to deal with the government, Yan Heng also feels that he does not need to rush to find a way as soon as he comes to the county seat.

Therefore, he plans to familiarize himself with this county in the next few days, and then look for the best opportunity to rescue his father.

This inn also operates a restaurant, which can be regarded as having everything, although Yan Heng and Xiao Yan Song have already had dinner, Yan Heng still asked Xiao Er to send a plate of fruit to their room.

He and Xiao Yan Song are now both growing up, and their nutrition must keep up, especially at night, how to eat some fruit to supplement vitamins, but people in this era don't drink milk much, otherwise it is naturally best to order a cup of pure milk at night.

Although his cousin and the strong man were executed by Jinyiwei, he had been covering Yan Song's eyes, and Jinyiwei also took care of his own and Xiao Yan Song's feelings, and immediately dragged the body into the dense forest after killing his cousin and the strong man.

In other words, Xiao Yan Song may not know why the cousin and the strong man who wanted to kill him and his brother at the beginning suddenly disappeared after screaming.

But this almost threatening his life still scared Xiao Yan Song, and because of this, Xiao Yan Song suddenly became very quiet along the way, and it was only when he entered the inn at this time that he recovered some of his senses from fear and fear, and asked Yan Heng curiously:

"Brother, what are you sprinkling today, why did you sprinkle it, my cousin and that big man cried, and I didn't see him after a while, and there were a few more people who looked fierce, could it be that brother, you will have a spell that only immortals, why didn't Xiao Yan Song know before?"

Xiao Yan Song also had no feelings for his cousin Yan Zhishi, so he didn't show any concern for Yan Zhishi, he was only curious about why the quicklime spilled by his brother could so magically subdue the fierce cousin and the big man, and also summon people who were gorgeously dressed and looked fierce.

Children's imagination is rich, they are also curious about mysterious powers and new things, and their desire for knowledge is particularly strong, which is the best time to learn and receive knowledge.

It is not like adults who are only trapped by the word "affection" and have no interest in exploring the truth of many phenomena.

"My brother sprinkled that is quicklime, its scientific name is calcium oxide, it will release a lot of heat after contact with water, and turn into mature lime, that is, calcium hydroxide, this is not the magic of the gods, this is the power of knowledge."

Yan Heng patiently explained to Xiao Yan Song, and he didn't want Xiao Yan Song to become a beetle who could only read the Four Books and Five Classics.

Today's mainstream learning is to make people know and be courteous, but it pays more attention to the cultivation of etiquette, and less the inheritance and enrichment of knowledge.

He felt that since he was an elder brother and a time-traveler, he could and needed to let his younger brother, the future Shousuke, know some knowledge that the education system of his current era could not give him, especially in the natural sciences and economics.

To be a good official, especially a good politician, sometimes you have to know a little bit about it, otherwise you can't control all aspects of the empire.

However, even if Xiao Yan Song is learning poetry and scriptures, he is still in the stage of swallowing dates, and he can't understand what Yan Heng said about quicklime, calcium oxide, etc.

Xiao Yan Song has an advantage, that is, as long as he doesn't understand it, he dares to admit it frankly, and he won't deny it.

Therefore, now that he saw Yan Heng say so many words that he felt unfamiliar with, he still shook his head honestly and pouted: "Xiao Song doesn't understand." ”

Yan Heng didn't reprimand him, he just didn't want to break his good habit and make him a person who didn't know how to pretend to understand, seeing him shaking his head, he just patted his little face affectionately:

"It doesn't matter if you don't understand, my brother will slowly teach you in the future, this world is composed of all kinds of elements from a certain point of view, and it is precisely because of the different compositions of the elements that there are all kinds of different things, such as this piece of straw paper with carbon as the main component will burn on the fire, and this silver nugget with silver as the main component will not, and even after the fire is burned, you can wipe it with your hands, and there will be no black traces."

Yan Heng put the candlestick on the table between himself and Yan Heng, burned the straw paper to ashes, burned the silver block for a while, and explained it to Xiao Yan Song.

Xiao Yan Song listened with relish, and hurriedly clapped his hands and said: "Wow, it's amazing, brother, you can teach me this in the future, Xiao Song'er doesn't want to learn the four books, those things are not as interesting as this." ”

"No way!"

Yan Heng directly rejected Xiao Yan Song's proposal, although he also knew that learning four books and eight stocks was boring and boring, but in this era he was the only way to verify IQ and cultivate officials who obeyed the rules.

Xiao Yan Song can't help but learn.

Fortunately, Xiao Yan Song was sensible, and when he saw that his brother was so strict, he had no choice but to purse his mouth and say, "Okay! ”

"Some knowledge is not to see whether it is interesting to learn, but to see whether it is useful, you know, now if we want to save our father, if we want to live a good life, if we want all the people in the world to eat chicken legs, we must learn these boring knowledge, but you can rest assured, my brother can teach you a lot of interesting knowledge in the future, such as making the lamp shine without oil and wax, and making the car run without a horse."

"Really? Is there really a way to make a lamp shine without oil or wax? ”

Xiao Yan Song jumped up for joy.

Yan Heng nodded, and then put up his index finger to stop Xiao Yan Song's curiosity to ask: "However, now you must eat the fruit first, after eating the fruit, my brother will continue to teach you to memorize the "Book of Filial Piety", and then go to bed after memorizing it, and then my brother will tell you a story and teach you conscious knowledge." ”

"Can you talk about interesting knowledge first, and then memorize the Book of Filial Piety?"

"No, only by memorizing the "Book of Filial Piety" can you save your father, save your father, and you will have the opportunity to see your little Lulu who has been thinking about it for a long time, and when you see Little Lulu, you can tell her interesting knowledge, understand?"

"Understood!"

Xiao Yan Song giggled after replying loudly, and lowered his head when he was about to leave: "I actually just want to see Xiao Lulu, I didn't think about it, brother don't talk nonsense." ”

Yan Heng couldn't help but shake his head and smile when he saw this, he was quite lively just now, and now when he mentioned Ouyang Lu, he also knew that he was shy.

Yan Heng felt that he didn't even know his younger brother Xiao Yan Song, and he couldn't imagine what kind of person he would become when he grew up, whether he would still be a thief or a virtuous minister.

Yan Heng doesn't know and can't really grasp a person's future development.

This is the consciousness that a teacher should have, you can't be sure whether your student will be a criminal or a great man in the future, you can only give him the most suitable and correct education at the moment.

Yan Heng felt that he still had a lot to do, but he could give Xiao Yan Song a lot of knowledge that he couldn't learn in this world, so he might be able to have some other inspiration.

Thinking of this, Yan Heng felt that he could use the database system in his mind to reorganize his knowledge structure and give Xiao Yan Song a complete syllabus other than Confucian academics.
