Huang Xiao nodded: "Exactly!" ”

Shi Kefa was surprised!

Zhu Youxiao was overjoyed: "Haha! That's great! This one has to be figured out! In the future, I will install one in the palace of the virtuous brother, if I have something, I can directly ask the virtuous brother! Ha ha! Brother Xian, tell Fang Yizhi about this principle! ”

Huang Xiao said with a smile: "As the saying goes, one know-how, all know-how, understand the working principle of wired telegraphy, if you want to make a wired telephone, it will be much simpler, secret, I will talk to you briefly, I believe that after you listen, you will definitely understand." ”

Fang Yizhi couldn't wait to get up and salute Huang Xiaoxing.

"Sir, please!"

Huang Xiaodao: "Sound-vibration-changing current, Mizhi, do you have any inspiration?" ”

Fang Yizhi wrote three nouns on the paper, sound, vibration, current, and was silent.

The trio didn't bother him either.

Shi Kefa sighed: "Science is really broad and profound, and students boast of being outstanding in their learning, and they are really ashamed!" ”

Huang Xiaodao: "There is a specialization in the art industry, and the constitution cannot be presumptuous, if I let you concentrate on learning these, I believe that you will also be successful, but your role now is not here, I brought you here this time, I just want you to let you learn all aspects of knowledge, and finally let you be in charge of the party, and after the world is decided, you have more time, and you can also join the study and research of scientific research." ”

Shi Kefa was excited, and his heart of loss disappeared.

"Ah, I see! I see! Ha ha! I'm so stupid! ”

Suddenly, Fang Yizhi shouted excitedly.

"Sir, after the current is transmitted through the wire, and then it is reduced to drive the magnetic object to vibrate, and the sound can be restored, isn't that true?"

Huang Xiao laughed: "Not bad! That's it! The telephone is divided into two parts: the earpiece and the microphone, and what you just said is the principle of the earpiece that is pushed backwards. ”

Fang Yizhi was ecstatic: "Great! Thank you sir! Sir, can you send me back, I'm going to study the test at once. ”

Huang Xiao laughed: "Don't worry, I don't care about this half a day, we will go to Tianjin Wei, and we will return in half a day." ”

Fang Yizhi smiled wryly, "Sir, the principle of wireless telegraphy and wireless telephony, you also reveal a little bit of ...... to the students."

Huang Xiao smiled: "Okay, but I won't tell you the principle, when you personally study it, that sense of pride and accomplishment is the best reward for your own efforts!" Is it? ”

Fang Yizhi said: "Yes! Last month, when the students made their own wind turbine for the first time, the sense of accomplishment was intoxicating, even though I also learned it from the textbook given by my husband! ”

Huang Xiao nodded: "I'll just say one word, you write it down, and then you study it yourself, I believe that in time, you will gain!" ”

Fang Yizhi responded solemnly.

Huang Xiao said slowly: "Electromagnetic waves." ”

Fang Yizhi was stunned, and then solemnly wrote it in his notebook.

Huang Xiao didn't say anything more, he just clicked from time to time, there was no need to teach by hand, he believed that with Fang Yizhi's talent and learning, he would definitely achieve something.

Huang Xiao did not fly to Jingshi to pretend to be forced this time, but went all the way to Tianjin Wei along the railway line.

Zhu Youxiao looked at the railway that winded like a giant dragon on the earth, and sighed: "Brother Xian, in just half a year, it is really changing with each passing day, at the beginning, the railway and the train were just a set of wooden toys on the desk of Brother Xian, but I didn't expect that now the railway has been repaired to Dahuangzhuang and connected to Jingshi, and it is about to open for operation!" It's like a dream. ”

Huang Xiao said with a smile: "The power of science and technology is huge, once science and technology begin to bloom, the promotion of society is extremely huge!" For example, the revolution represented by the steam engine, known in history as the first industrial revolution, a large number of machinery was developed and applied! ”

"That industrial revolution was mainly carried out in the West, that is, this industrial revolution, the West completely left the countries with traditional manual production far away, and the hegemony of the empire on which the sun never set was established!"

"Now the steam engine was first developed in China, although the current change is not so drastic, but I believe that with the passage of time and the popularization of education, it will definitely burst out of its charm, not to mention that we are already studying the electrical science that triggered the second industrial revolution."

Zhu Youxiao laughed: "Okay! Good! With the help of my Daming, Daming will definitely lead the world! Become an empire on which the sun and moon never set! ”

As he spoke, Tianjin Wei Airport was already in sight.

Yesterday, Zhu Youxiao had already sent someone to inform Fang Kongzhao overnight, and in the vicinity of the airport, Fang Kongzhao, officials at all levels, and even soldiers and ordinary people had already waited respectfully by the airport.

The plane came to a steady stop at the airport under the kneeling of thousands of people.

Zhu Youxiao and Huang Xiao were the first to get off the plane, and Shi Kefa and Fang Yizhi also got off the plane.

"Minister, Fang Kongzhao, the governor of Tianjin Wei, and the officials and people of Tianjin Wei, meet Your Majesty and meet King Xian!"

"Flat."

The crowd stood up.

Huang Xiao looked at one of the people in the team and shouted, "Erxiao, come here!" ”

"Your Majesty! Master! ”

Erxiao knelt in front of Huang Xiao excitedly!

"Get up, call a few people to help carry the things, and send them all to the governor's palace."

"Yes!"

Erxiao got up, ordered Sun Yun's team, and accompanied by Shi Kefa and Fang Yizhi, went to the cabin to carry the currency.

Fang Kongzhao also greeted Zhu Youxiao and the two of them into the sedan chair that had been prepared long ago and went to the governor's mansion.

Zhu Youxiao and Huang Xiao sat down.

Fang Kongzhao, Sun Xiudao, and more than a dozen officials stood on both sides.

Erxiao and Sun Yun's team also sent the currency to the governor's palace.

Huang Xiao looked around and asked, "Second filial piety, where is your brother?" ”

The second filial piety said: "My eldest brother heard that His Majesty and the young master were coming, so he went to sea overnight, saying that he wanted to offer auspicious rui to His Majesty and the young master, but it is a pity...... Haven't rushed back yet. ”

Zhu Youxiao asked: "What auspiciousness?" ”

Erxiao said: "This ...... Sun Yun, come on. ”

Sun Yun said: "Your Majesty, the deputy governor and the second filial piety heard from King Xian before, saying that there is a huge Peng Kun in the sea, and it just so happens that after the construction of the ironclad ship is completed, a new fishing boat is built, and the deputy governor wants to go deep into the sea to find Peng Kun, and wants to give His Majesty a surprise." ”

Sun Yun is more articulate than Erxiao.

Huang Xiao smiled dumbly, in today's weather, it is not easy to hunt whales.

Zhu Youxiao said with a smile: "I also heard King Xian talk about this huge sea beast, at that time, the two brothers seemed to be present, I didn't expect them to remember this matter, they have a heart, don't do this in the future, it's too dangerous." ”

Fang Kongzhao and the others were all relieved, this matter was really a little inappropriate, but Liu Daxiao's temperament was unyielding, and Fang Kongzhao had no choice but to follow him.

Zhu Youxiao looked at Sun Yun with interest: "Are you catching fast?" ”

Sun Yun said neither humbly nor arrogantly: "Yes! I am the captain of the first security team of the Tianjin Ministry of Health and Security. ”

Zhu Youxiao asked: "Are you the only woman?" ”

Sun Yun said: "Now there are seven women in the security team and me, and in addition, there are three women who are officials, a total of ten people. ”

Zhu Youxiao laughed: "Okay! Good! I am preparing to vigorously promote women to officials, Governor Fang, you have done a good job and dared to break the rules, which is commendable! ”

Fang Kongzhao said: "The minister is also under the guidance of King Xian, he dares to let women as officials, and the minister found that women are indeed as King Xian said, and they are more convenient than men in some jobs, such as Captain Sun, who is fast in arresting female prisoners, and is also very careful in interrogating prisoners. ”
