Chu Zhen played the prepared video.

First, a section of the steam engine, in the form of animation for the Ming monarchs to demonstrate its principle and several structures, let them think for a while, Chu Zhen played the early steam train.

"Whew!!"

The huge iron carriage whistled and the waves rolled in, and the industrial-age steel aesthetic suddenly stunned everyone—they didn't necessarily appreciate it, but they were certainly surprised by the power of the steel monster.

The wheels of the train rolled slowly forward, and everyone opened their eyes wide as they watched the train pass by one by one.

Zhuangyuan Lang Hualun counted silently in his heart, there were a total of twenty carriages, and they were all filled with black coal!

"How can there be such a long car?!"

"This car...... I'm afraid that I can transport ten thousand stones of grain! ”

"Is there a long iron on the ground? …… I see, it turned out that the wheels of the train were running on it! ”

"Coal-burning car?!"

With the discussion of everyone, the camera slowly moved up, and everyone followed the train, after a transition, the train traveled between the mountains and mountains, and then a transition, the train traveled on the vast grassland, billowing white smoke and the sound of the wheels clanging, extremely shocking!

Tanhualang Huang Zicheng's gaze is firmly fixed on the train in the picture, a car dozens of zhang long, transporting 10,000 stones of coal at a time, crossing mountains and mountains, from south to north, what kind of power is this?

Boiling water contains such great power!

After the video was played, everyone was immersed in the shock brought by the long steel monster for a while.

After a while.

Chu Zhen said with a smile: "The principle of the train looks simple, but in the next thirty years, Daming can pave a thousand-mile-long train track, which is already quite remarkable, which requires talents from many disciplines, and Daming has just started." ”

"Thirty years?"

Zhu Yuanzhang calculated in his heart that it would take a few years to go to sea, a few years to fight the Northern Yuan, and a few years to overseas silver mines, and twenty or thirty years is indeed not much.

He shouldn't be able to see this, and he can only rely on the standard to complete it.

"Next, I'll tell you what mathematics, physics and chemistry are!"

Chu Zhen gave a formal lecture, mathematics, physics and chemistry again, what is the use, what to learn, how to learn, etc., which is equivalent to making a guide to the new textbook, and the rest depends on them.

"That's the end of today's lesson!"

Chu Zhen ended cleanly and gave the microphone to Zhu Yuanzhang.

"I would like to thank Chu Zhenjun for the radio station that he gave to Daming, as well as for tonight's lecture."

Zhu Yuanzhang's words spread, and everyone saluted Chu Zhen one after another, even the people on the wall were no exception, the scene was truly spectacular!

"The imperial court has set up a telegraph department, the rank is from the fourth grade, in addition to transmitting the military affairs, there are another fifty radio stations for the use of the people everywhere, and Chu Zhenjun has given another ten radio stations for the soldiers stationed in Yunnan to use for free!"

Zhu Yuanzhang set the responsibilities of the Telegraph Department, and according to the results of the consultation with Chu Zhen, he kept some of the 200 radio stations for safekeeping, and divided the rest into official and civilian use, so that the people of the world could benefit.

From now on, the letters of the people of the Ming Dynasty will be more than half faster, and they only need to send the letters to the telegraph office in the provincial capital, and then transmit them to the provinces and distribute them to the prefectures and counties.

In places with large populations, two or three more radio stations can be allocated.

According to the life of modern instruments, it is not a problem to use a radio station for twenty or thirty years, but the charging instrument is easy to be damaged.

But let's talk about this later, with the current situation, it will not be a hassle to maintain the operation of hundreds of radio stations.

Plus the other four dynasties are the same.

"Class! Goodbye, classmates. ”

Chu Zhen announced the end of tonight's class.

It's a pity that there is no teacher goodbye, and everyone salutes him, saying that Zhenjun will see you in the next class.

It was still Your Majesty, Chu Zhenjun, the crown prince, King Yan and others went first, and everyone left in an orderly manner according to their grades.

"Alas, it's a pity, the next time Zhenjun will give a lecture for the last time, and I don't know when I will hear it."

Hua Lun was immersed in the knowledge he had just learned in class, and suddenly heard someone talking, and couldn't help but be taken aback, and hurriedly grabbed him: "Brother Tai, what did you just say?" Mako-kun's next lecture will be the last?! ”

Everyone around looked at each other, and judging from their expressions, they were the same as Hua Lun, and they didn't pay attention to what Chu Zhenjun said.

"You don't know? At the beginning, when the last video was played, Chu Zhenjun said that he would only give a lecture again, and the rest of the knowledge and knowledge would depend on us to learn! ”

"This ...... Alas. ”

Hua Lun couldn't help but be stunned, and couldn't come back to his senses for a long time.

Although he only listened to the lecture once, this class shocked him a lot, and his eyes were suddenly opened, and he jumped out of the Confucianism he had studied for more than ten years and saw the vast world.

But now, Chu Zhenjun said that he would only teach them one more time!

What a sorrow!

A jinshi said to him enviously: "If Hua Zhuangyuan can stay in Yingtianfu, most of us top three jinshi can only go to other places, and we will never hear Chu Zhenjun's lectures again!" ”

The surrounding jinshi sighed, and Hua Lun was once again glad for his high school champion.

But I can't help but think, how long will Zhenjun's next lecture be after?

I heard that Zhenjun only came to the Ming Dynasty once in a few months, and he no longer responded to Tianfu throughout the winter, and only went to Yunnan once.

In this way, I'm afraid that the true monarch will only appear in Beiping Mansion when he is fighting Liaodong?

……

Chu Zhen stayed in Wangjiang Tower for three days.

Because of the big news, the Daming newspaper printed an additional issue, and directly printed 100,000 copies, Ying Tianfu will definitely not be able to sell out, and it needs to be sent to various places.

But this issue of the newspaper published the Telegraph Division, 100,000 copies are not too many, as long as there is a need for inter-provincial letters, the Telegraph Division will be used in the future.

Chu Zhen went to see Luo Guanzhong, who was in charge of the Daming newspaper, chatted with him for a long time, and made up the author information of two of the four famous novels, and the time and space points rose by 3,000.

On the fourth day, Chu Zhen and the crown prince Zhu Biao saw off Zhu Di.

This time, Zhu Di took three radio stations back to Beiping Mansion, one official and one civilian, these two stayed in Beiping Mansion, and one was given to the generals patrolling the border outside the Saiwai to report the military situation at any time.

"Chu Zhenjun, big brother, stop, take care!"

After leaving the city, Zhu Di said goodbye to the two.

"Fourth brother, take care!"

Zhu Biao stopped the horse.

Chu Zhen smiled: "The next time I see you, it will be when you lead the army to conquer Liaodong." ”

Zhu Di also smiled: "In a few years, it will be me who will lead the army to the Wa Kingdom, Chu Zhenjun is going?" ”

"How can you not go to destroy little Japan?"

Chu Zhen laughed.

After seeing Zhu Di go away, he also said goodbye to Zhu Biao, and then returned to Haicheng.

As for the horse just ridden, let Zhu Biao send someone to take it back.

……

"I'm back!"

Chu Zhen, who returned to the second floor of his living room, shouted, and the two ancient girls who looked down to study his computer raised their heads and showed a delicate smile at him.

Chu Zhen's heart melted into these two beautiful and graceful faces.

"Mr. is back from a lecture~?"

Li Qingzhao greeted him, and Shuwan's beautiful face was full of smiles.

Chu Zhen pulled her back and pressed her to the chair, Li Qingzhao looked up at him and listened to him say, "Mr. punished you to write a hundred poems!" ”

"Ah...... A hundred? The slave family can't write it, but Mr. spares the slave family~"

Li Dacai's miserable voice, Daiyu on the side covered her mouth and smiled, and also looked at Uncle Chu, but saw him stunned for a moment, and looked at Sister Qing with his eyes.

Daiyu didn't know what she meant at first, but when she saw Sister Qing, she suddenly bowed her head shyly, and then she understood:

Sister Qing's coquettish appearance just now made Uncle Chu look like a dumb goose!

"What is Chu Langjun looking at?" Daiyu asked him.

"What is Sister Lin talking about?"

was borrowed by her to call Chu Langjun again, and Li Qingzhao wanted to arrest her and punish her.

Daiyu said: "I think it's because my sister is too beautiful, so Chu Langjun is so fascinated that he forgets where he is, but it's a bit of an eyesore for my sister to stay here." ”

Sister Lin's jealous appearance was indescribably cute, Li Qingzhao actually laughed out loud, covered her mouth and turned around to laugh.

Chu Zhen sat down, pulled Lin Daiyu's hand over and put it in his arms, and then pulled Li Qingzhao's hand over, grabbed the soft and slender jade hands of the two with one hand, and said with satisfaction: "Now I am in a daze, I have forgotten where I am, I just hate to last forever!" ”

Daiyu's face flushed, but she didn't break away in the end, let him hold it, and her fingertips also touched Sister Qing's hand, and the two glanced at each other through Chu Zhen, and they couldn't help but be a little ashamed.

The three of them are clear.

Chu Zhen just wants to marry the two of them, one is being married to the Ming media in the Song Dynasty, and one is also being married to the Ming media in the Dashun Dynasty.

"What were you just looking at?"

Chu Zhen changed the topic in a timely manner and couldn't chase too closely.

"I'm idle and watch some news." Daiyu turned her head to look at him: "What did Chu Langjun do in the Ming Dynasty?" ”

"Also mention Lang Jun!"

Li Qingzhao said angrily, Sister Lin covered her mouth and shook her head at her, saying that she was wrong and begged for mercy.

"I didn't do anything, I just took a lesson."

Chu Zhen looked at the webpage and found that they were just reading an article posted by a fashion blogger that taught people to dress up.

Li Qingzhao asked the question he had just asked at this time: "The women here in Langjun are all ...... in the summer Dressed like this? ”

"Yes."

"Really......?"

Li Qingzhao's face was red, he reached out to hold the mouse, took the web page back, and immediately jumped out of some girls wearing cool swimsuits, revealing snow-white straight thighs, narrow waists, and smiling at the camera on the beach.

Lin Daiyu covered her eyes with her two small hands on the spot and turned her head.

Don't look at indecent acts.

Li Qingzhao was also shy, and didn't dare to look at Chu Langjun, the woman on the computer screen seemed to have become her, and she would be in front of Langjun in the future...... Wear these clothes?

"That's right."

Chu Zhen admired the shy and moving expressions of the two girls, and couldn't even look up at Li Qingzhao, and Sister Lin was even more ashamed.

After a while, Chu Zhen chuckled and said: "The atmosphere of later generations has opened up a lot, just like the Tang Dynasty, women are all crisp breasts and half-exposed. ”

"Definitely!"

Li Qingzhao blushed, and gave him a serious science popularization: "The half-sleeved skirt is also the dress that the East Palace maid often worships." Even if this kind of clothing was originally worn only by the women of the palace to please the emperor, even if it was later spread, few people dared to wear it in the court, the inner court, or the singer in the church. ”

"There's no such footing... Also exposed. ”

Li Qingzhao looked at the picture of the swimsuit again, and the more shy he felt.

"Uncle Chu has also seen other women dressed like this?" Lin Daiyu's fingers opened a slit, and her eyes stared at him.

"Uh-huh, ahem!"

Chu Zhen was embarrassed to say that the university had swimming lessons, and he was tired of watching it.

Not to mention that he has collected some ...... on his computer.

I will delete it later, so that they don't see it, and if you want to see it in the future, you can look at the two of them directly, which is better than any photo.

He is also surrounded by old classmates who are studying overseas.

No matter how bad it is, go to the Grand View Garden, see Qin Keqing, Xue Baochai is okay, the looks and figures of the two are unique, and they have their own merits. There are also Qingwen, Zijuan, and Xiangling.

It seems that the nun of Miaoyu also hides a good ......

Sins, sins, sins.

Chu Zhen hurriedly closed the webpage, so as not to think of Li Qingzhao and Sister Lin also wearing swimsuits from the girls in swimsuits.

However, Li Qingzhao is okay, and may accept to play on the beach in a swimsuit after a while.

But Lin Daiyu would never go to those places and show off her arms and thighs in a swimsuit.

At most, wear it at the pool at home and show it to him.

In other words, if you want to enjoy Dolling's sister's swimsuit, you have to buy a large villa with a swimming pool.

You can't dig a pool in the Grand View Garden, right?
