Soon, the door of Li Changfeng's mansion was surrounded by people.
It is difficult for everyone to understand how the lights shine.
Li Changfeng was still sleeping until the sun was noon and Eunuch Zhang came from the palace to issue an order, and he was awakened by Bingbing and Xiaotong.
When Eunuch Zhang saw Li Changfeng, he smiled and said, "Your Highness, Your Majesty is welcome."
Li Changfeng yawned and complained.
"I can't sleep well. What's wrong with my father telling me?"
"It's not because of the electric light you invented by Your Highness. Your Majesty was very surprised after hearing this. He specially asked me to invite you over."
Eunuch Zhang was still a little shocked at this time.
When he heard about this early in the morning, if Li Changfeng hadn't done it, he wouldn't believe anything.
How can we shine at night without lamp oil or candles?
It's simply a fantasy.
When he came to Li Changfeng's mansion, he stayed at the door of the mansion for a while, carefully observed the lights, but after looking at them for a long time, he still couldn't understand them.
Li Changfeng was not surprised by this. Everything was in his plan, but he didn't expect Emperor Gan Wu to be so impatient.
Li Changfeng was not in a hurry. He washed up and had breakfast before he went to the palace with Eunuch Zhang.
When Emperor Gan Wu saw him, he went straight to the point and asked, "I heard that you have created something called electric light that emits very bright light at night, and does not need candle lamp oil?"
Li Changfeng nodded: "That's right."
"Why does it shine?"
"Uh... this explanation is quite complicated. Do you know?"
"Dragon? What is that?" Emperor Gan Wu looked confused.
Li Changfeng had no choice but to explain patiently.
"Let me say that, electricity is a kind of... Well, clean energy, I know that you can't understand Father. In winter, you will make a crackling sound when you touch the metal when wearing fur clothes, and you can even see the lightning. It's that kind of thing .”
"So...you mean, that kind of thing, what kind of electric light is going to shine?"
"That's right."
"this……"
"The details are more complicated. This involves the principle of electromagnetics. To put it simply, it is..."
Li Changfeng explained the principles in a simple and easy-to-understand way as much as possible, and Emperor Gan Wu was still confused when he heard it.
Finally, Li Changfeng added: "This is why Erchen invested a lot of money in scientific research. By studying the objective laws of things, he could use it."
Emperor Gan Wu frowned and thought for a long time but couldn't figure it out. Finally, he sighed helplessly.
"I'm increasingly unable to understand what you're doing now."
Li Changfeng chuckled and said, "This is what professionals do, it is what they are good at. Father, what you are good at is to govern the world. Everyone has their own things to do, and Father, don't worry."
Emperor Gan Wu asked with a bright look: "But, why do I think you are good at everything and know everything, just like an omniscient and omnipotent person?"
“Is there any?”
"have!"
Emperor Gan Wu stood up and stared at Li Changfeng with confusion in his eyes, amazed, proud, very complicated, and said after pondering for a moment: "Sometimes I even feel that you are a little strange. I often think at night, are you really my son? ?”
Li Changfeng's heart tightened. Could it be that Emperor Gan Wu discovered the matter of soul-piping?
It's impossible.
Emperor Gan Wu is a mortal.
Even if it is an extraordinary existence, it is impossible to discover it.
He was puzzled and said in surprise: "How could Father have such an idea?"
"Think about what you are doing, artillery, firearms, hot air balloons, steam trains, steamships, these things can be barely understood. Now I have created another electric light, I don't understand what you are saying at all, it seems that these things are originally It does not exist in this world, it is like it was copied from another world."
Li Changfeng suddenly realized.
The industrialization process in his previous life was rapidly advanced by him with his own strength, so Emperor Gan Wu was like this.
To put it bluntly, it is uneducated.
Li Changfeng's natural light would not tell Emperor Gan Wu, and he thought for a while and said, "Father, do you believe there are geniuses in this world?"
"Of course I believe that you are."
Li Changfeng shook his head: "You can think of me as a genius, and everyone in the research institute is a genius. And the core personnel, such as Liang Dafu, Tang Yi and others, are all geniuses among geniuses. Before they can show their great talents, they , Erchen spent a lot of money to train them in Baishi City for ten years! Without them, there would be no big work today."
Emperor Gan Wu stared at Li Changfeng: "I feel like you are deliberately weakening the role you play in it."
"No." Li Changfeng smiled, "I just wanted to tell my father that everything today is the accumulation of my son over the past ten years. From this process, I realized the importance of studying things and learning knowledge, so I tried my best to promote the reform of the education system."
Upon hearing this, Emperor Gan Wu fell into deep thought and nodded after a moment.
"You're right."
Seeing the success of transferring the words here, Li Changfeng added: "When the big work grows stronger, the reform of the education system must be promoted nationwide."
“This is inevitable.”
Li Changfeng joked: "Father, you specifically asked someone to come to the palace. Isn't it just to tell me that you suspect that I'm not your son?"
Emperor Gan Wu glared at him: "Is I so bored? I am very interested in that electric light and I can also make a set of it in the palace. You, a brat, can't use all the good things alone?"
"That's definitely not. I've prepared a set of things. I'll verify it at home and I'll install it for you soon... But, I won't let you tell me about this in person, right?"
Emperor Gan Wu nodded.
"That's natural. After hearing this, I thought about it. Is it possible that the whole people of the big kids use electric lights?"
Li Changfeng was waiting for this sentence from Emperor Gan Wu, and he suddenly felt enlightened.
"Of course, but it's a bit inappropriate to use a steam engine as a power source. In fact, it's not impossible. You can set up a thermal power plant... but this will pollute the environment, so you can do water and electricity in one step..."
Li Changfeng began to introduce the principles of the hydropower station to Emperor Ganwu in an easy-to-understand way as possible. Emperor Ganwu was confused at first, but gradually became shocked.
He stood up and paced back and forth in the imperial study room, his mind seemed to be extremely shocked. After a moment, his eyes were staring at Li Changfeng tightly.
"You mean... cut off a river and use water to get some?!"
"That's right."
“Can water generate electricity?”
"certainly."
"……Why?"
"This involves another knowledge point, the gap potential energy..."
Li Changfeng thought for a while and felt it was difficult to explain these to Emperor Gan Wu, so he said helplessly: "This is difficult to explain. Father, you don't need to know these things. You just need to know that you can generate electricity in this way."
