"...The lightning in nature is not essentially different from the electricity we emit with electromagnetic induction today. It's just that the voltage we emit is very small and does not harm the human body. However, lightning in thunderstorms can turn human electricity into coke. Therefore, when thunder is thunder, it is best not to stand under a tree or carry metal objects such as swords, and not to fly kites in thunder and lightning weather, or you will be responsible for the consequences!"

After Li Xiu finished the above paragraph, he packed up his textbook and said again: "Okay, let's talk about the knowledge about electricity today. In the next class, we will talk about artificial power generation and the possible applications of electricity in the future. In addition, a few people in the front row will help you and move this simple generator to the library and get off the get out of class!"

With Li Xiu's "subsidy", the course related to electricity finally ended. However, many students were still immersed in Li Xiu's previous narrative, especially the unprecedented field of electricity, which was like opening an unprecedented door for them. The generator was even more magical. Although the current emitted was invisible, it could make people feel that every student who had experienced it in person was trembling all over by the electricity, just like a legendary spell.

Li Xiu was not surprised by the students' addiction expressions. After packing up the textbooks, he directed several students to help move the generator to the academy's library. This generator was made by him to teach the children at home. Now he simply gave it to the academy and it was placed in the library. It can be operated by students in person in order to experience the magic of electricity.

The generator was placed in a separate room in the library. After all, the library requires quietness, but if someone wants to try the generator, it may be difficult to keep quiet. However, as soon as this simple generator was installed, Xiao Yu walked over excitedly and said, "Mr. Concubine, can I try this thing?"

"Mr. Xiao, have you seen someone else's reaction after being electrocuted just now? Why bother to try it yourself?" Li Xiu smiled bitterly when he heard Xiao Yu's request.

Although Xiao Yu is the chief of the academy, as long as Li Xiu gives lectures, he will take time to listen, even more seriously than ordinary students. In the class just now, Li Xiu lets the students experience the feeling of being electrocuted, but Xiao Yu is eager to try it out. However, Li Xiu is worried that he is old and the chief of the academy. If he is really trembling with the electric shock in front of the students, his image will also affect his image. So Li Xiu just ordered a few young students to go on stage, but he deliberately ignored Xiao Yu. Unexpectedly, he ran over again.

"That's different. Others are others, and they are themselves. The electricity you talk about is so wonderful. If you don't experience it yourself, how can you have a deeper understanding?" Xiao Yu said with a firm expression. It seemed that he was determined to try what it felt like to be electrocuted?

Seeing Xiao Yu's attitude so firm, Li Xiu had no choice but to nod and agreed, and then let the other party hold the wire of the current output, and then rotate the generator himself. However, considering Xiao Yu's age, Li Xiu deliberately slowed down. However, even so, Xiao Yu could feel the numbness of his palms and even his arms. If the current was a little stronger, he might have to tremble all over like those students.

"It's amazing. This small device can emit electric current that makes people unable to control their bodies. I really don't know what power the lightning in the sky is?" After experiencing the feeling of being electrocuted, Xiao Yu couldn't help but sigh.

"Everything in the world has its own reasons, so I named this discipline physics. Only by understanding the operating principles of these things can we understand the world we are in more accurately." Li Xiu also smiled and said, very happy that everyone in Confucian scholars like Xiao Yu could experience the wonders of physics, and even influence his thoughts on these things.

"The truth of everything is my way? As the saying goes, three thousand great ways, and they all come to the same path. If you study this physics to the extreme, you may be able to reach my level!" Xiao Yu nodded in agreement when he heard Li Xiu's words.

Although he is older, he still maintains a desire to learn. Therefore, as long as Li Xiu gives lectures during this period, he will go to listen to the lectures. The more he learns, the more he feels the extraordinary learning that Li Xiu teaches. Although these knowledge is different from Confucianism, it is more meticulous and practical. Many questions that he couldn't understand before, after Li Xiu's explanation, people often feel a sudden enlightenment.

When Li Xiu heard Xiao Yu compare physics with Lao Tzu's Tao, he laughed at the moment, and did not admit it or deny it. Physics is science, Lao Tzu's Tao is metaphysics. However, even in later generations, the explanation of the world is full of uncertainty. Neither science nor metaphysics seems to be unable to explain this world. When science in the next world has not reached its peak, perhaps human beings can develop for thousands or tens of thousands of years before they can figure out the essence of this world.

"By the way, does the prince-consort know that the Persian envoy is coming to the Tang Dynasty again?" But at this moment, Xiao Yu suddenly heard him speak again, and shift the topic to an aspect that Li Xiu could not react.

"This... I heard about it. After all, I am quite familiar with the Persians, but this time the Persian envoy seems to have been replaced." Li Xiu was stunned for a moment before he reacted.

Just a few days ago, the Persian envoy arrived in the Tang Dynasty again, but this time the envoy was no longer Bahra. It is said that Bahra could not be used for the envoy, so he changed to a Persian minister. I heard that he was very old and Li Xiu had never seen him, so I didn't know much about this Persian envoy.

However, although Li Xiu had never seen this Persian envoy, he had heard about something. According to the original history, the capital of Persia should have been violated by the cannibals two years ago. A country has no capital, and even if the king is still alive, it can almost be said to have destroyed the country.

However, under the influence of the Tang Dynasty, Persia formed an alliance with the Roman Empire. When the Dashi attacked Persia, Rome sneaked into the Dashi's army from behind, which led to the Dashi's defeat of Persia. Persia also took this opportunity to regain a lot of territory in one fell swoop. However, the Dashi's man was not willing to fail. After recuperating for a while, he actually fought against two, and was not at all inferior. This shocked Rome's man's strength. At the same time, he was also somewhat grateful to have an alliance with the Persians under the persuasion of the Tang Dynasty. Otherwise, he would not be the opponent of the Dashi's man.

"It's a coincidence that I went to the palace to meet His Majesty the day before yesterday. I happened to meet the Persian envoy and also met His Majesty. The envoy was named Zamas. He was an old Persian with white hair and beard. It is said that he was a famous Persian scholar. Moreover, his mission not only included Persians, but also some Roman envoy. But the Roman envoy died on the road, so now the mission is mainly Persians." Xiao Yu immediately told the situation he learned the day before yesterday.

"There are Romans in the mission?" Li Xiu couldn't help but show a surprised expression when he heard this news. He had only heard that the Persian mission had arrived, but he didn't know that the Romans had also come with the Persians. However, this was not surprising. First, the Persian mission had just arrived in Chang'an and had not seen the sky. He probably had been waiting for Li Shimin's summoning. Second, Li Xiu now came to the academy at home and rarely had contact with the outside world, so the news was not particularly well-informed.

"Yes, the book of the Later Han Dynasty calls them the Qin Dynasty, and now we call them Rome, and I remember that this title was first called from the prince consort. However, whether it is Rome or Persia, I see that the Hu people look similar, red and white, and their hair color is different from ours, and they look quite strange." Xiao Yu couldn't help but smile when he saw Li Xiu's surprised look.

"Haha~, in the eyes of our Central Plains, the Hu people are indeed similar, but Rome and Persia used to be a feud, and both sides were almost immortal on the battlefield. Now they are facing the threat of a great cannibal, and they have to join forces. At the beginning, His Majesty wrote a letter to the Roman emperor himself, which led to their alliance with Persia." Li Xiu also said with a smile.

The alliance between Persia and Rome has temporarily curbed the expansion of the cannibal, which is also a good thing for the Tang Dynasty. After all, if the cannibal continued to expand, the Tang Dynasty was also seeking to control the Western Regions. In this way, the two sides would sooner or later collided. The Battle of Henglus in later generations was the first collision between two great powers, but the Tang Dynasty's national strength was declining at that time and was no longer able to control the Central Asian area.

"I know that the prince consort is very familiar with the last envoy of Persia. This time Persia sent envoys again and would probably visit the prince consort. As far as I know, there are many scholars in the Persian mission, such as the envoy Zamas, who is a famous Persian scholar, so I want to ask the prince consort to do a favor and ask the Persians to come to the academy to communicate. If possible, they can also tell the students about the knowledge in Persia." Xiao Yu finally explained his purpose at this time.

The atmosphere in all aspects of the Tang Dynasty was quite open. Although scholars like Xiao Yu were arrogant, they were not particularly xenophobic in their academic studies. At least they were much more tolerant than in the Ming and Qing dynasties in later generations. This was also one of the reasons why Li Xiu's courses were very popular in academies. Therefore, when Xiao Yu knew that there were many scholars in the Persian and Roman missions, he couldn't help but have the idea of ​​seeking curiosity. He wanted to learn about the knowledge of the people in the West through communication?
