"This... next year may be a bit unsustainable. I guess I will have to wait until the next year at the earliest." Li Xiu hesitated and replied. Mr. Ma asked about the time to attack Goguryeo again. 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.

"Will the next year?" Mr. Ma was silent when he heard this. After a while, he spoke again, "Okay, Su Dingfang had been in trouble with Goguryeo for several years. It is estimated that Goguryeo's margins will be almost ruined, and he will be more confident at that time!"

"Yes, Your Majesty is actually in a hurry to destroy Goguryeo as soon as possible. However, now our Tang Dynasty is becoming more and more prestigious. If it is not good for the army, it will greatly damage the reputation of our Tang Dynasty, so we have to be careful!" Li Xiu also spoke when he heard this. There are many reasons why he did not attack Goguryeo now, but what he said is also one of the most important reasons.

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

"This..." Li Xiu hesitated for a moment before speaking, "I'm not very clear, but if His Majesty wants to personally conquer Goguryeo, someone will definitely need to stay here in Chang'an. I don't know who His Majesty will leave?"

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

"But in just two years, Uncle Ma, you might as well go to the army to fight. At that time, you can definitely wash away the shame of the past and bring back your old subordinates in that year!" Li Xiu said deliberately and relaxedly at this time.

"Okay, if I can move in two years, I don't have to say that I will follow you, but if..." When Ma Ma said this, he suddenly couldn't continue, and Li Xiu looked depressed at this time. In fact, he knew what Ma Ma meant. At Ma Ma's age, he could say that he would be less than one day. Even though he was still showing off his strength just now, he was not sure to live for another two years, so he told Li Xiu to help him fulfill his wish.

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

When Ma Ye heard that Hen'er was about to have a child, he immediately raised his interest and immediately said with a happy look on his face: "Although Hener had given birth to a court before, I still hope to have another grandson. And I have calculated that Hener may be pregnant with a boy this time, and I will have two grandsons at that time!"

Seeing Ma Ye’s happy look, Li Xiu also congratulated him repeatedly, and then the two began to talk about naming the child. Hener’s first child was not with Ma Ye when he was born, so the child’s name was named by Shangguan Yi. However, this time Ma Ye clamored to name the child. However, he was from a military general and his level was limited. As a result, he thought of several names and was not even satisfied with him, so he asked Li Xiu to take the initiative.

Although he doesn't even know the gender of the child now, Li Xiu naturally doesn't believe it as for the fortune teller. However, he is also accompanying Mr. Ma, so he helps to think about the name seriously. However, he was not satisfied with mentioning Mr. Ma in a row. It seems that Mr. Ma is also very confused about this matter.

He accompanied Ma Ye to catch fish for a day. The next day, Li Xiu went to the financial management supervisor to expose him and then went home to teach his children. Speaking of which, he rarely had time to teach his children during this period, and it was not a solution to keep Wu Mingkong and others in his place. After all, although they learned well, it did not mean that they were teaching well, so it was okay for them to replace them temporarily, but over time, it would definitely delay the children's homework.

"What we are going to learn today is electromagnetic induction, and I have something very interesting to you for you to try!" Li Xiu stood in front of the blackboard of the school, holding a physics textbook in his hand and said with a smile. Physics is the focus of his teaching. He had already told his students in advance that there was a lot of physics knowledge that had not been applied to actual use. As for whether they can be applied to reality, it depends on their understanding.

"Sir, what is electromagnetic induction?" As soon as Li Xiu finished speaking, he saw Li Zhi asking first. Since Empress Changsun passed away, he and Yizi have come to Li Xiu's place almost every day. First, they are for class, and second, they can play with their younger sisters, so as not to know their elder brothers and sisters when they grow up.

"Haha, 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 something I made first. You will understand it yourself!" Li Xiu said again with a smile at this time. After saying that, he went out of the school himself and then pushed forward a strange thing from outside.

This thing looks a bit like a bicycle from later generations, but it has no wheels. Instead, it is connected to a dense coil at the back, and there are several magnets fixed outside the coil. In fact, this is a simple generator. If explained in physical terms, it is an electromagnetic induction device.

Looking at this strange generator, Li Zhi and others below were puzzled, not understanding what this thing is for, but Li Xiu smirked at this moment, pointing at Li Zhi and said, "Zhi Nu, let's play a game. Do you believe it or not, I can't touch you, and you can jump up 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 were not consistent with common sense at all.

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

Anyone who has learned a little physics knows that the coil will generate current when it moves in a magnet. Of course, the current generated by Li Xiu's simple generator is not strong. At first, Li Zhi didn't feel anything, but as the coil turned faster and faster, he felt his hands numb, which scared Li Zhi very much. Moreover, this numb feeling began to spread along his arms and throughout his body, which made him look horrified. Finally, he couldn't help but scream and let go. At the same time, his feet kicked uncontrollably and actually jumped up.

"Wow~" The students below couldn't help but scream when they saw that Li Zhi actually jumped up. After all, they didn't believe it when Li Xiu said he wanted Li Zhi to jump up by himself.

"What's going on with this sir? Why do I feel numb all over and I can't control myself?" Li Zhi took a few steps back before standing up, and then rubbed his arms while asking in confusion. If he hadn't been listening to Li Xiu's class since he was a child, he would even think that Li Xiu was using some magic?

"Haha, when metal moves in a magnetic field, it will generate a certain charge. What you just felt was the effect of electricity. This electricity is essentially the same as lightning when it rains, but the energy of lightning is too great. If it hits a human, it can almost turn into coke, but this electricity can only make you feel numb all over your body." Li Xiu explained with a smile at this time. When he said this, he looked at his students again with malicious intentions and said, "Who else would like to try what it feels like to be electrocuted?"

"Try it. Although it felt a bit weird at first, it felt pretty good after being shot!" Li Zhi, a dark-bellied guy, also encouraged him. He suffered a loss himself and hoped that others would suffer with him.

However, Li Xiu's students were not stupid either. They all lowered their heads and dared not look at Li Xiu, for fear that he would ask him to go up. It is worth mentioning that since Li Jin and Ping Anlang went to study separately, most of Li Xiu's students were girls. Apart from Li Zhi, there was only Wang Fangyi, a boy, so Li Xiu's eyes also fell on him.

Wang Fangyi is eleven years old this year. He doesn't talk much and is a boring person. In the past, he had a lot of conversation with Ping Anlang, but now Ping Anlang goes to study medicine, and he talks less. Compared with other students, his presence is quite low. Sometimes even Li Xiu ignores himself as a student.

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

"Okay, Fang Yi, you have the courage!" Li Xiu was overjoyed when he saw Wang Fang Yi standing up. He hadn't played enough yet, and the current emitted by this simple generator was not strong, and it did not harm the human body.

Wang Fangyi gritted his teeth and went up, but naturally, like Li Zhi, he jumped up by electricity. Li Xiu also took the opportunity to talk about the principle of electromagnetic induction. With the reference of real objects, coupled with the experiment just now, their memory can be deeper.

After the morning class was finished, Li Xiu took the children to have dinner together. The family set up a canteen for these children, and they would eat together at noon, which could also deepen their relationship. However, during the meal, Wang Fangyi brought his own food to Li Xiu and sat down next to him, and said very seriously: "Sir, I have something I want to discuss with you!"
