"...the lightning in nature and the electricity we emit today with electromagnetic induction, there is no difference in nature, but the voltage we send out is very small, there is no harm to the human body, but the lightning on thunder can be used as coke, so when thundering, you are best not to stand under the tree, or carry metal items such as a sword, not to fly a kite in the lightning weather, take a hot steamball and other acts, otherwise the consequences are self-defeating!"

After Li Hugh said the above words, while packing up the textbook, he said again: "Well, today we will talk about the knowledge of electricity here, the next lesson we will talk about manual power generation, and the possible application of electricity in the future, and a few people in the front row to help, this simple generator will be moved to the library, after class!"

With Li Hugh's "out of class", this course related to electricity has finally ended, but many students are still immersed in Li Sheu's previous telling, especially the unprecedented field of electricity, as if they opened an unprecedented door, and the generator is even more magical, although the electric current can not be seen, but it can be felt that every parent who has experienced the students has been trembling with electricity, almost like the magic of legend.

For the students addicted to the expression, Li Huo has long been surprised, after packing up the textbooks, and commanded several students to help move the generator to the library library, this generator or he in order to give the children at home to the class made, now sent to the library, and usually placed in the library, usually can also let the students personally operate, in order to experience the magic of electricity.

The generator was placed in a separate room in the library, after all, the library asked for quiet, but if someone wanted to try the generator, I am afraid it would be difficult to keep quiet, but this simple generator had just been placed, and saw Xiao Xing rushed to walk quickly and said: "The horse, can I try this thing?"

"Xiao Gong, have you just seen the reaction of others after the electric shock, why do you have to try it yourself?"Li Huo heard Xiao's request but smiled bitterly.

Although Xiao is the mountain chief of the college, but as long as Li Xiu lecture, he will take time to listen, even more serious than the average student to listen, just now, Li Huo let students experience the feeling of being electric, the result is Xiao is also eager to try, but Li Huo is worried about his age, and is the mountain chief of the college, if it is really in front of the students by the whole body trembling, but also affected his image, so Li Huan just ignored a few young students on stage, but deliberately ignored Xiao.

"That is not the same, others are others, they are themselves, you talk about the electricity so wonderful, if you do not personally experience the same, how can you have a deeper understanding?" 」Xiao is a firm expression, it seems that he is iron-hearted to try to be electric.

Seeing Xiao's attitude so resolute, Li Huo could not help, and finally had to nod his head and promise, and then let the other party hold the wire of the current output, he personally turned the generator, but considering Xiao's age, Li Hue also deliberately slowed down, but even so, Xiao can feel the feeling of tingling his palms and even his arms, if the current is a little stronger, I am afraid he must also tremble like those students.

"It's amazing, this little device can emit a current that people can't control the body, and I really don't know what kind of power is the lightning in the sky?"After Xiao experienced the feeling of being charged, he could not help but feel very emotional.

"Everything in the world has its own truth, so I named this discipline physics, and only by figuring out the workings of these things can we more accurately understand the world we live in."Li Hue also smiled and spoke at this time, and he was also very happy to let Xiao such a Confucian everyone experience the wonders of physics, and even affected his ideas on these things.

"The truth of all things, that is not the way of Lao Tzu, the so-called road of three thousand, the same way, this physics if studied to the extreme, perhaps can also reach the realm of Lao Tzu!"Xiao heard Li Hugh's words and nodded in agreement.

Although he is older, he still maintains a heart of learning, so as long as Li Huan lectures, he will run to listen to lectures, and the more he learns, the more he feels that Li Xiu teaches extraordinary learning, although these studies are different from Confucianism, but more meticulous and practical, many problems that he could not think of before, after Li Huan's explanation, people often have a sudden feeling of openness.

Li Hugh heard Xiao compare physics with Lao Tzu's Tao, now is also a laugh, did not admit or deny, physics is science, Lao Tzu's Tao is occult, but even in the future, the interpretation of the world is also full of uncertainty, whether it is science or occultism, it seems that it can not explain the world, of course, the science of the future has not yet reached the extreme, perhaps mankind has developed thousands of thousands of years to find out the essence of this world.

"Do you know that the envoys of Persia are coming to the Tang Dynasty again?"But at this time, suddenly only listened to Xiao speak again, and also shifted the topic to an aspect that Li Hugh could not react to.

"I have heard this, after all, I am familiar with the Persians, but this time the Persian envoy seems to have changed."Li Huxuan for a moment before he reacted.

Just a few days ago, the Persian envoys once again arrived in the Tang Dynasty, but this time the envoys were no longer Bahrah, and it was said that Bahrah could not make a fortune, so he changed a Persian minister, and he heard that he was very old, and Li Hu had not seen it, so he did not know much about this Persian envoy.

However, although Li Hugh has not seen this Persian envoy, he has also heard some things, according to the original history, two years ago, the capital of Persia should have been broken by the big cannibals, a country without a capital, even if the king is still alive, it can be said to be almost destroyed.

However, under the influence of the Tang Dynasty, Persia and the Roman Empire, in the big food attack on Persia, Rome from behind the attack on the big cannibal army, the result led to the defeat of the big food soldiers in Persia, Persia also took advantage of this opportunity, regained a lot of land, but the big cannibals are not willing to fail, after a period of recuperation, even with an enemy, and do not fall, which makes Rome on the great cannibalism.

"It is also a coincidence that the day before the day before I had come into the palace to meet your majesty, and I had just met the Persian envoy who was also worshipped by His Majesty, and this envoy, named Zamas, an old Persian who was all white, and was said to be a famous scholar of Persia, and that of his mission not only the Persians, but the Roman envoys were dying on the road, so that the mission was now mainly Persians."Xiao now explained what he had learned the day before.

“Are there Romans in the mission?”Li Huo heard the news can not help but show a surprised expression, he only heard that the Persian mission came, but did not know that the Romans and the Persians came, but this is not surprising, one is the Persian mission just arrived in Chang'an did not see the sky, it is estimated that has been waiting for Li Shimin's summons, two Li Xiu now in addition to the home is to come to the library, rarely contact with the outside world, so the news is not particularly well-informed.

"Yes, the Han Dynasty called them the Great Qin, and now we call them Rome, and I remember the name or the first to call it from the horse, but whether it was Rome or Persia, I think they looked alike, red, white, and white, and the hair color was different from us, and it looked rather strange."When Xiao saw Li Huo surprised, he couldn’t help but laugh.

"Haha, in the eyes of our Central Plains, the Hu people are indeed the same, but Rome and Persia were once enemies, and the two sides were almost immortal on the battlefield, and now they are facing the threat of big cannibalism, and they have to unite, and when their majesty wrote a letter to the Roman emperor, only to promote their alliance with Persia."Li Hue also said with a smile at this time.

The alliance between Persia and Rome has temporarily curbed the expansion of the cannibal, which is also a good thing for Datang, after all, if the big cannibals are constantly expanding, and the Tang is also seeking to control the western region, so that the two sides will sooner or later collide, the battle of Henros in the future is the first collision of two major powers, but the decline of the great Tang national strength at that time has been unable to control Central Asia.

"I know that the horse is very familiar with the last envoy of Persia, and this time Persia sent the envoys, and it is likely to visit the horse, and as far as I know, there are many scholars in the Persian mission, such as the famous scholar of Zamas, who is making Zamas, so I would like to ask the horse to help, and then ask the Persians to come to the school to exchange, if possible, let them tell the students about the knowledge of the Persian side."At this point, Shaw finally made his own purpose clear.

The style of Datang in all aspects is still quite open, such as Xiao these readers although there are arrogant, but in the study is not particularly exclusive, at least compared to the future Ming and Qing Dynasty to be more inclusive, which is one of the reasons why Li Sheu's course is very popular in the college, so Xiao knows that there are many scholars in the Persian and Roman missions, but also can't help but wonder the idea, want to understand the extreme of the world.

For Xiao's idea, Li Huo naturally raised his hands in favor, but he was worried that Zamas would come to visit himself?After all, the other side is not Bahr, and this time Bahr did not come, which makes Li Hugh a little strange, after all, Bahr is more familiar with the Tang, according to reason, the Persian side should not easily change the envoys, unless it is Bahra encountered what problem?
