"This ...... Next year may be a bit in the air, and I guess it will be the year after next at the earliest. Li Xiu hesitated at this time and replied, Ma Ye once again asked about the time of the attack on Goguryeo, and Li Xiu also knew what he was worried about, but this matter was not something he could control, even Li Shimin had to wait patiently for the opportunity.

"The year after tomorrow?" Ma Ye also fell silent when he heard this, and after a long while, he spoke again, "It's okay, Su Dingfang has been harming Goguryeo for several years in a row, and it is estimated that Goguryeo's little family background has almost been lost, and he will be more sure at that time!" ”

"Yes, Your Majesty is actually anxious to destroy Goguryeo as soon as possible, but now that the prestige of our Datang is growing, if it is unfavorable, it will greatly damage the prestige of our Datang, so we have to be careful!" Hearing this, Li Xiu also said, there are many reasons not to attack Goguryeo now, but what he said is also one of the most important reasons.

Ma Ye nodded silently after hearing this, and then after a long while, he spoke again: "Boy, I heard that Your Majesty wants to go to Goguryeo in person, will you go then?" ”

"This ......" Li Xiu hesitated for a moment when he heard this, and then said, "I don't know very well, but if Your Majesty wants to conquer Goguryeo in person, there will definitely be someone left behind in Chang'an, and I don't know who Your Majesty will leave behind?" ”

"I hope you can go with Your Majesty, and help me bring back the brothers who died in Liaodong when the time comes!" When Ma Ye said to the end, his face couldn't help but show a sad look, when Yang Guang conquered Goguryeo, countless Central Plains athletes buried their bones in Liaodong, especially the last time, Goguryeo piled up the bones of the dead and wounded Sui army into Jingguan, including Ma Ye's old subordinates, he is now old, and his last wish is to be able to bring the bones of those old subordinates back to his hometown for burial.

"But it's only been two years, and when Uncle Ma comes, you will simply go out with the army, and when you go to Goguryeo, you will definitely be able to wash away the shame of the year, and by the way, you can also bring back those old subordinates of yours back then!" Li Xiu deliberately said lightly at this time.

"Okay, if I can still move in two years, I don't need you to say that I will follow, but in case I ......" When Ma Ye said this, he suddenly couldn't go on, and Li Xiu also looked gloomy at this time, in fact, he knew what Ma Ye meant, with Ma Ye's current age, he can say that he will live one day less than one day, even if he is still stubborn just now, but in fact, he himself is not sure that he will live for another two years, so he will ask Li Xiu to help him fulfill his wish.

"Uncle Ma, Hate'er will give birth in a few months, do you think it will be a boy or a girl this time?" Feeling that the topic was a little heavy, Li Xiu immediately changed the topic and said, after Shangguan Yi was transferred back to Chang'an a few years ago, he never left, and lived in Ma Ye's mansion with Hya'er, so that it was convenient to take care of him and the county lord of Guanghua, and Hate'er was pregnant last year, and it is estimated that she will give birth in July this year.

As soon as he heard that Hate Er was going to have a child, Ma Ye's interest was immediately raised, and he immediately said with a happy face: "Although Hate Er has given birth to Tingzhi before, I still hope to have another grandson, and I have found someone to calculate, Hate Er is likely to be pregnant with a boy this time, and I will have two grandchildren by then!" ”

Seeing Ma Ye's happy appearance, Li Xiu also congratulated him repeatedly, and then the two began to talk about naming the child, when the first child was born, he was not by Ma Ye's side, so the child's name was taken by Shangguan Yi, but this time Ma Ye was clamoring to name the child, but he was born as a military general, and the level in his stomach was limited, so he thought of a few names and was not even satisfied with himself, so he asked Li Xiu to consult.

Although he doesn't even know the gender of the child now, as for the fortune teller, Li Xiu naturally doesn't believe it, but he is also accompanying Ma Ye anyway, so he also takes the trouble to help think of the name, but he is not satisfied with mentioning a few Ma Ye in a row, it seems that Ma Ye is also entangled in this matter.

Accompanied Ma Ye to fish for a day, the next day Li Xiu went to the financial supervisor to show up, and then went home to teach the children to read, speaking of which, during this period of time, he also rarely had time to teach the children, and it was not a way to let Wu Mingkong and them replace themselves, after all, although they learned well, it did not mean that they were good at teaching, so they temporarily replaced it, but after a long time, it would definitely delay the children's homework.

"Today we're going to learn about electromagnetic induction, and I've got something really interesting for you to try!" Li Xiu stood in front of the blackboard in the school, holding a physics textbook in his hand and said with a smile, physics is the focus of his teaching, and he has already told his students about the physics knowledge that has not yet been applied in practice, as for whether they can be applied to practice, it depends on their understanding.

"Sir, what is electromagnetic induction?" As soon as Li Xiu's words fell, he saw Li Zhi and asked first, since the death of Empress Changsun, he and his son-in-law have come to Li Xiu almost every day, one is to attend classes, and the other is to play with his sister Xin'er, lest the little guy grow up and don't know his brother and sister.

"Hehe, what is electromagnetic induction, this matter is a bit complicated to explain, so I won't talk about it for now, let's take a look at a thing I made first, and then you will understand it by yourself!" Li Xiu said again with a smile at this time, and after speaking, he personally walked out of the school, and then pushed a strange-shaped thing from the outside.

This thing looks a bit like a bicycle in later generations, but it has no wheels, but a dense coil connected to the back, and a few magnets are fixed outside the coil, in fact, this is a simple generator, to explain it in physical terms, this is an electromagnetic induction device.

Looking at this strange-shaped generator, Li Zhi and the others below were also puzzled, and couldn't understand what this thing was for, but Li Xiu laughed evilly at this time, and pointed at Li Zhi at the moment and said: "Pheasant slave, let's play a game, do you believe it or not, I don't have to touch you, I can make you jump by yourself?" ”

"I don't believe it!" Li Zhi couldn't help but shake his head when he heard Li Xiu's words, because Li Xiu's words didn't conform to common sense at all.

Li Xiu was waiting for Li Zhi's words, and then he asked the other party to come up, and then grabbed the two wires of the generator with his hands, and personally sat in front of the generator and kicked it hard, and the knotted leather rope also turned, and then drove the coil of the generator behind to rotate.

As long as anyone who has studied a little physics knows that the coil will produce an electric current when it moves in a magnet, of course, the current generated by Li Xiu's simple generator is not strong, Li Zhi didn't feel anything at first, but as the coil turned faster and faster, he also felt numb in his hands, which made Li Zhi also frightened, and this numb feeling began to spread along his arm to the whole body, which made him show a frightened expression, and finally couldn't help screaming and letting go, and at the same time, his feet kicked uncontrollably, and he really jumped up.

"Wow~" The students below couldn't help but exclaim when they saw that Li Zhi really jumped, after all, when Li Xiu said just now that he would let Li Zhi jump by himself, they didn't believe it very much.

"Sir, what the hell is going on, why do I feel numb all over my body, and I can't control myself?" Li Zhi took a few steps back before standing up, and then asked puzzled while rubbing his arms, if he hadn't listened to Li Xiu's class since he was a child, he would even think that Li Xiu was doing some magic?

"Hehe, when the metal moves in a magnetic field, it will produce a certain charge, what you just feel is the effect of electricity, this electricity is essentially the same as the lightning when it rains, but the energy of lightning is too large, if you split people, it can almost turn people into coke, but this electricity can only make you feel numb all over your body." Li Xiu explained with a smile at this time, and when he said this, he looked at his students again with bad intentions and said, "Which of you still wants to try what it's like to be electrocuted?" ”

"Give it a try, although it feels a little weird at first, but after being electrified, it still feels pretty good!" Li Zhi, a black-bellied guy, also agitated beside him, he suffered a loss himself, and he also hoped that others would suffer with him.

However, Li Xiu's students are not stupid, they all lowered their heads and did not dare to look at Li Xiu, for fear that he would call him up, it is worth mentioning that since Li Jin and Ping An Lang went to study separately, most of Li Xiu's students are girls, except for Li Zhi, there is only Wang Fangyi A boy, so Li Xiu's eyes also fell on him.

Wang Fangyi is eleven years old this year, usually he doesn't talk much, and he is relatively boring, he used to talk to Ping An Lang very much, but now Ping An Lang went to study medicine, and as a result, he has fewer words, compared to other students, his sense of existence is also quite low, and sometimes even Li Xiu ignores himself as a student.

Wang Fangyi also lowered his head, but he felt that Li Xiu had been looking at him, and he didn't want to disappoint Li Xiu, so he could only stand up and say, "I'll give it a try!" ”

"Okay, Fang Yi, you have a lot of courage!" Li Xiu saw Wang Fangyi stand up, and he was also overjoyed at the moment, he hadn't played enough, and the current emitted by this simple generator was not strong, and it was not harmful to the human body.

Wang Fangyi went up hard, and the result was naturally the same as Li Zhi, he was electrocuted and jumped up, Li Xiu also took the opportunity to talk about the principle of electromagnetic induction, with the reference of the real thing, coupled with the experiment just now, it can also make their memory more profound.

When the morning class was over, Li Xiu took the children to eat together, and the family set up a special canteen for these children, and they ate together at noon, which could also deepen their relationship, but when eating, Wang Fangyi came to Li Xiu with his own food and sat down, and then said very seriously: "Sir, I have something I want to discuss with you!" ”
