The soft sunlight reflected on Li Xiang's delicate face, and Zhao Mengyao's heart warmed, since he didn't let her hide, it meant acknowledging her identity. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 info It's just that she is the daughter of the Great Khan of the Mongol Empire, the Great Song Dynasty and the Mongol Empire are destined to be enemies, and Li Xiang is an official of the Great Song Dynasty, she is destined to not be Li Xiang's wife in this life, she doesn't care about her identity, but what she cares about is how Li Xiang treats him in his heart.

Li Xiang patted her little face and teased: "Don't hurry up, Huan'er is waiting outside!" ”

Sure enough, in response to Li Xianggang's words, Huan'er called softly from outside: "Son, it's time to get up, the slave family brought you your favorite osmanthus cake!" ”

Zhao Mengyao listened to the soft voice of the ring outside the door, glanced at Li Xiang, and then got up and dressed. It's just that after wearing it for a long time, I had to wear a dirty dress, just because Li Xiang was so rude last night that she tore almost all of her clothes.

Seeing Zhao Mengyao looking at the broken clothes in his hand in a daze, Li Xiang scratched his head in embarrassment and said bitterly: "You stay on the bed, I'll open the door!" He hurriedly put on a single coat and went to open the door.

The door was finally opened with a "squeak", and Huan'er stood at the door with a tray, and said with a small face: "Childe, it's all three poles in the day, how can you get up!" Squeezed through Li Xiang's body and walked towards the house.

Li Xiang scratched his head, his face was embarrassed, he couldn't say, I got up a long time ago, I was just making love with Zhao Mengyao.

Sure enough, as soon as Huan'er walked to the table and put down the tray, she saw Zhao Mengyao who was sitting on the bed at this time, Huan'er was puzzled at first, why did Zhao Mengyao appear in Gongzi's room early in the morning, Xuan'er saw the fragments of clothes on the ground next to the bed, and saw Zhao Mengyao only wearing obscene clothes, how could she not understand what was going on, no wonder Gongzi opened the door for such a long time!

Li Xiang saw that Huan'er's face was not natural, and he looked at Zhao Mengyao on the bed in a daze, and couldn't help but say loudly: "Huan'er, you ......"

Huan'er snatched the words and smiled reluctantly, "Childe, you... Eat breakfast, the slave family won't bother you! With that, he covered his mouth with his right hand and ran out.

Li Xiang raised his hand, but he didn't stop it after all.

Zhao Mengyao was dressed in obscene clothes, hurriedly walked to Li Xiang's side, and said angrily: "Don't chase it yet!" ”

Li Xiang smiled bitterly, shook his head, and said, "Forget it, I know Huan'er, let her be quiet at this time, I'm afraid it will backfire if you catch up." ”

Huan'er's state made the two no longer in the mood to talk to each other, and hurriedly ate some osmanthus cake that Huan'er put on the table, Zhao Mengyao flashed back to his room, and Li Xiang was also thinking about how to continue to develop Shaoxi Mansion.

Now Li Xiang's life is two points and one line, in short, he travels back and forth between Shaoxi Mansion and Rongde County.

Now that the electric motor and generator have been successfully made, even Li Kang and the officials of Shaoxi Mansion feel that it is amazing that there can still be their own machines in this world.

Li Kang and his son, Wang Lin and other officials came to Duzuo Courtyard again, and now the motor has been running for a while, Li Xiang looks like there is no problem, and the room is crowded with dozens of people, fortunately, this room is not small, and it will not be too crowded for a while.

Li Xiang demonstrated the motor to everyone again, and everyone's surprise was no less than Wang Lin and others, Wang Lin participated in the entire manufacturing process after all, and was somewhat mentally prepared, but the officials who came at this time saw such a situation for the first time, and they were already stunned, and no one spoke quietly for a while, only a low buzzing sound.

After a while, it was finally Zhao Erfeng, the senior official and magistrate, who spoke first, and his voice trembled a little: "Lord Li, this is ...... This is called an electric motor, which really turns on its own, so please explain the principle a little bit or two. Although he was surprised, he thought that there must be a reason why the motor would never move on its own.

Li Xiang praised: "Lord Zhao is worthy of being a knowledgeable person, and he knows that the reason why this machine can operate automatically must have a reason. As he spoke, he explained the principle that the battery can generate electromotive force and an electric current in the conductor, and the current can produce a magnetic field, and called everyone to the front of the motor, and explained the role of each part in detail, but considering the time relationship, the right-hand rule of electromagnetism and the unit of magnetic field strength were not explained.

Despite this, everyone has roughly understood the principle, but the principle of the battery is not well understood for a while. Li Xiang saw that everyone was very eager, so he patiently explained the principle of the battery again, and said the concept of "electricity" for the first time.

In fact, in ancient times, the concept of electricity was mostly derived from thunder and lightning, but as for artificially generated electricity, it was the first time that everyone had heard of it. Li Xiang had no choice but to briefly draw a diagram to illustrate how energy is converted from chemical energy to electrical energy, and then from electrical energy to mechanical energy, and also explained that the battery also has a time when it is exhausted, so this motor will not keep spinning, and will naturally stop rotating when the battery is exhausted.

Then he talked about the principle of generators, which can generate electricity from both water and wind.

When explaining these questions, Li Xiang tried to use as few unfamiliar words as possible, for fear that everyone would be suspicious, thinking to himself what is the origin of this Master Li, who knows so much knowledge? In fact, Li Xiang's worries are a little redundant, at this time, everyone is thinking about electric motors, where will they consider where this knowledge comes from? Even if there is occasional suspicion, it is impossible to imagine that these technologies will come from hundreds of years later.

After talking to everyone, Li Xiang smiled and said: "Everyone, in fact, the reason why the motor can be built is all thanks to electromagnetism in physics, and I only know this knowledge by chance, and I will naturally tell you about it in the future, so I am not in a hurry to figure out the principle for a while, as long as I know that there is such a thing." Everyone listened excitedly, and watched in the room for a while, until Li Xiang disconnected the power supply, which slowly dispersed, and still kept discussing the various uses of this motor.

When Wang Lin heard this, an unnatural expression appeared on the boss's face, and after a while, he said, "Master Li, I don't know if I can build some of the telescopes last time?" This is because there is a problem during our drills in the past few days: After the shells are fired, the soldiers have to walk far away to observe whether the target is destroyed, and some of them waste time, not to mention, they will be injured by mistake if they don't get it right, and besides, with the telescope, the artillery can also show the enemy situation in advance. ”

When Li Xiang heard him say this, he already fully understood in his heart that in fact, the military use of the telescope was not only for artillery aiming, but also for military reconnaissance, but since Shi Ji found out this reason, Li Xiang was not easy to refuse, but there was no glass in the Song Dynasty, and it was not easy to build a telescope.

Li Xiang said with a sad face: "Lord Wang, there are still some difficulties in the production of our glass lenses, of course, this is not a big problem, and after our glass factory is completed, it will naturally be able to achieve mass production." ”

Last time, Li Xiang used the super 3D printer in his body to print a pair of binoculars, which attracted these people. Not only is it fresh, it's also functional. (To be continued.) )
