Wu Sangui saw a young man pointing at him and talking sharply, he was a little strange, but he immediately reacted when his mind turned, and the one in front of him was Yongwang Zhu Cihuan.

"Wu Sangui has seen His Royal Highness King Yong!" Wu Sangui got up and knelt down towards Zhu Zihuan, and Chen Yuanyuan also got up and knelt next to Wu Sangui.

This time, Liu Lan didn't stop it, in the end, Wu Sangui went to North America, saying that he was surrendering to Zhu Yujiao, but in fact, he still surrendered to the Zhu family, and it was good to let Cihuan teach him a lesson here.

"That's it, get up, I'm not the Yongwang, when my father asked you to bring troops into King Jingqin, you shirked it in every possible way, and now Uncle Luo promised to let you go to North America, if you hear that you have half-heartedness for your sister, don't look at the long road, the Wehrmacht is going to destroy you, it's just a gesture!"

At this time, Zhu Cihuan revealed the princely atmosphere that he had cultivated in the palace, and Wu Sangui knelt on the ground and did not dare to move, listening to Zhu Cihuan's reprimand.

"Wu Sangui swears to the sky that he will never dare to disagree again, please rest assured His Royal Highness King Yongwang!" Wu Sangui said while kowtowing.

Luo Jian came out of the study with a map and happened to see this scene, but he didn't go over to stop it, just stood there and watched quietly.

When Wu Sangui got up from the ground, Luo Jian came over, and without mentioning what happened just now, he spread out the map on the coffee table.

This map is a map of North America in another time and space, and the east side of the map has been marked with a lot of red marks, which is the territory that Zhu Yujiao and they have occupied. Judging from the map, Zhu Yujiao's current sphere of influence is only confined to the east coast, and in the final analysis, it is only a line along the coast.

But the Ming Dynasty in North America is going to develop inland after all, and Luo Jian took out the map. It is to ask Wu Sangui to land from the east coast this time. From east to west.

Wu Sangui saw the map of the North American continent for the first time in a relatively complete way. Although he joined the North American Working Committee, Wu Sangui only went for a few days and couldn't stand everyone's cold eyes, and he didn't want to go anymore, and he didn't see the map from there in the past few days.

"Such a big place?" Wu Sangui asked stupidly.

"Hehe, this is a map of the whole world, you can compare it." Luo Jian smiled and unfolded the world map again.

As a general in the army, Wu Sangui is very familiar with maps. Although the map Luo Jian had taken out was quite different from what he had seen before, he still understood that the North American continent was much larger than the territory under the jurisdiction of the Manchu and Nanjing governments.

"You can have your own territory, but you must obey the jurisdiction of the Ming court." Seeing that Wu Sangui was looking at it seriously, Luo Jian pointed to the east coast of North America on the map and said.

Wu Sangui didn't speak, staring at the map, and his heart began to turn over the river and the sea. After churning in his mind for a long time, Wu Sangui found the biggest problem, that is, there are too few people.

"Metropolitan Governor, in such a big place, we still have too few people!" Wu Sangui hesitated. Or said the doubt in my heart.

"It can't be helped, we have limited capacity at the moment. This is on the one hand, and on the other hand, there are not so many people willing to go, this one can only be done slowly. ”

Luo Jian actually wants to immigrate to North America in large numbers, but now it really can't, after the natural and man-made disasters at the end of the Ming Dynasty, the current population of the whole China is only sixty or seventy million, and China's own development will be limited by insufficient population in the future, not to mention the new addition of sulfur ball, Hawaii Island, and Taiwan that is about to be recovered.

Luo Jian told Wu Sangui the details of the North American continent for a long time, and answered many questions raised by Wu Sangui, and the time was almost noon.

"Uncle Luo, don't talk about him, I have something to tell you." Zhu Cihuan sat next to him and quietly watched Luo Jian talk to Wu Sangui, and felt that the two of them had almost spoken, so he spoke.

"Oh, what's wrong with Cihuan? I thought you were here to play. Luo Jian said with a smile.

"Uncle Luo, how can I have time to play? I'm here today to tell Uncle Luo that we made it! Speaking of this, Zhu Cihuan's face finally showed a smile, and his eyes lit up all of a sudden.

"What succeeded? Cihuan, you mean you got a generator? "Luo Jian has actually heard Xiao Liu say a long time ago that the generator has been made, but the problem of electric lights has not been solved for a long time.

Luo Jian and Liu Weimin did not tell Zhu Cihuan that their research team would use tungsten filament in the light bulb in the future, but they just let them explore it themselves, and they didn't even say that the light bulb had to be vacuumed.

Luo Jian and Liu Weimin have specially discussed this issue, and on the road of scientific and technological exploration, there will definitely be many "detours", but these "detours" are often the door to another science and technology. If you directly tell them the research results of people in the future, then Zhu Cihuan's research team can only become senior technicians, and there will be no scientific research.

In order to lay a solid foundation for science, Luo Jian and Liu Weimin decided to only provide some directional suggestions and goals to all research groups, including Zhu Cihuan's electromagnetic research group, and did not say anything about the specific process and conclusions.

Just like the internal combustion engine that Song Yingxing was studying, Song Yingxing wanted to dismantle the warrior car to study, but Liu Weimin resolutely did not agree, and was reluctant to do it on the one hand, on the other hand, it was made out according to the cat and the tiger, and it was a great harm to the development of mathematics and engineering machinery design.

On the contrary, when Chen Zilong developed the bullet production line, although he spent countless energy and money, in this process, not only a more sophisticated machine tool was developed, but also a large number of technical personnel were trained, and Liulan's bicycle factory was successfully built, thanks to this.

"Uncle Luo, we have already made the generator, and I am here today to tell you that we have got the electric light." Saying that, Zhu Cihuan ran outside the door and came in with a cardboard box, carefully placed the cardboard box on the coffee table, and then opened it and took out a huge light bulb.

Everyone looked at Zhu Cihuan's hand curiously, Luo Jian estimated that the round light bulb was about the size of a football, and dragged out two wires, like two braids.

Carefully taken from Zhu Cihuan's hand, Luo Jian held it in his hand and observed it carefully, the glass is a little thick, it is estimated that they think that the thicker the glass, the less easy it is to break, and it seems that the seal is not vacuumed, I don't know how long such a bulb can be lit.

"Tzu Huan. Have you done a test? How long does such a bulb last? Luo Jian asked.

"Uncle Luo. We tried dozens of materials, and now the filament is made of carbon filament, which can only be used for about a quarter of an hour, and the filament is about to burn out. Zhu Cihuan said with some annoyance.

"Cihuan, I suggest you go to Liu Cui'e's chemistry research group, I heard that they have made great progress in the research of materials, maybe you can find new materials from them, and then solve the problem of why they burned. Aren't you really successful? Luo Jian still didn't want to tell Zhu Cihuan the answer directly, but just provided Zhu Cihuan with a method.

"Uncle Luo, you must know how to get it, right? Just tell us how to do it? At this time, Zhu Cihuan showed what a boy should look like.

"Hehe, Uncle Luo must know how to get it, but I can't tell you, you have to explore this slowly by yourself, and besides, I told you, you don't have a sense of accomplishment, right?" Luo Jian said with a smile.

Seeing that Zhu Cihuan was a little frustrated, Luo Jian pointed to the light bulb placed on the coffee table and said, "You guys have made great progress by getting the electric bubble out in such a short time." That's amazing, just what you've achieved on this light bulb. It was not at all stronger than Wang, and they were slightly worse off on the battlefield with great victories. ”

Wu Sangui and Chen Yuanyuan were both attracted by Luo Jian's words, just this round glass ball is more powerful than destroying tens of thousands of Qing soldiers? This is beyond their comprehension.

Luo Jian saw their doubts, smiled, and then said: "Don't underestimate this thing, after a while, when it is perfected, a new era will come." ”

"Cihuan, how is the telegraph research going now?" Luo Jian saw that Zhu Cihuan had not yet come out of his depression, so he changed the topic and asked.

"Uncle Luo, there are special people working on the telegraph, and it is estimated that it will be able to be made in two months, but the current generator is still unstable, and the output voltage is sometimes high and sometimes low." Zhu Cihuan said that the instability of the generator is not a theoretical problem, and the main process does not meet the requirements.

The principle and technology of the telegraph are provided by Luo Jian, this is really no way, the current battlefield command and information dissemination is too uncomfortable for Luo Jian, not to mention that with the construction of the railway, the need for long-range communication has been imminent.

Although Luo Jian was in a hurry to get the telegram out, there was no way to solve the problem of material technology, and it could not solve these problems, it could only be an experimental thing, and could not be put into practice.

"Uncle Luo, I want to bring the electric light to my sister, can you see it?" Zhu Cihuan looked at Luo Jian and said with great anticipation.

"Cihuan, the current electric light is not very practical, should we make some improvements to it, and when it can be fully used, let's bring it to my sister again, do you think it's okay?" Luo Jian understood Zhu Cihuan's thoughts very well, but this thing is really useless now, what is the use of only lighting a light bulb for fifteen minutes?

"But we can't do anything we can't, I don't think we can solve the light bulb problem in a short time." Zhu Cihuan said in extreme frustration.

Seeing Zhu Cihuan's extremely depressed appearance, Luo Jian thought about it for a long time, and felt that this kid was indeed too difficult, so he simply told him some key techniques.

After hesitating for a moment, Luo Jian still decided not to say it, in another time and space, scientists have studied the properties of many metals in order to find the filament in the bulb, and the achievements made in this are far beyond the comparison of a filament.

"To study something, you must have a spirit of perseverance, Cihuan, but you can't back down because you encounter some difficulties. I can understand the feeling that you want to bring the electric light to my sister, but after such a long distance, the practicability of the light bulb is not strong now, why don't we get it completely and give it to my sister? We will have regular ships to North America in the future, Cihuan, you don't have to worry about not having the opportunity to bring your sister. ”

Luo Jian slowly enlightened Zhu Cihuan, after all, Zhu Cihuan was only a sixteen-year-old boy, although he had experienced ups and downs in the past few years, his mind was far from mature, and Luo Jian was very worried that the temperament he had cultivated in the palace would affect his research.

"Uncle Luo, don't worry, I will persevere, I just hate myself for why I didn't get it out earlier, I can let the fleet bring it to my sister after the New Year, I have dreamed several times that there is no light at night there is no light there at night, and my sister is most afraid of the dark." The sixteen-year-old said with tears in his eyes.

"Cihuan, as long as you work hard and persevere, you can not only bring light to your sister, but also to the entire human race, if you succeed, you will create a new era." Luo Jian continued to encourage Zhu Cihuan.

Listening to Luo Jian's words, Zhu Cihuan nodded heavily, and his face showed a resolute look again. (To be continued.) )
