After glanced at Li Zhi, Gu Qing explained: "Actually, we live in a huge magnetic field."

"I don't understand!" Li Zhi shook his head vigorously.

"You know the compass." Gu Qing said, "The compass is the best thing to test the existence of a magnetic field. It cannot be seen or touched, but it does exist. We can use theory to concrete it and then prove it with practice."

"I still don't understand." Li Zhi said again, "and the electricity you mentioned, why does the rotor inside have electricity when cutting the magnetic field."

"..." Gu Qing also said for a moment. How to explain this? He had long forgotten it when he was in class. "Your Highness King Jin, you will understand when you make the generator."

"Really?" Li Zhi was puzzled.

"Well, serious." Gu Qing nodded vigorously.

"Looking at your expression, I know you are teasing me again. Do you think I will believe your nonsense?" Li Zhi turned his head and walked into the house disdainfully, "Yizi? Are you here? Your prince, I'm hungry."

"There is a cake on the table!" The elephant who was embroidering responded.

Gao Yang was embroidering with Xiao Yizi. He usually danced with swords and swords, but he still couldn't handle the work of embroidery.

"Sister, take your time, don't worry." Xiao Yizi said, "Mingda learned it for a long time."

Gao Yang put down the embroidery in his hand and looked at the cake outside and said, "Zhinu, can't you make what you want to eat yourself?"

Li Zhi was frightened by Gao Yang's sudden tone of gunpowder. He couldn't help but think of Gu Qing's words. It was because women couldn't see through their hearts, especially pregnant women, who were even more difficult to mess with, let alone her own princess. Li Zhi took the cake and returned to his study.

"The emperor has been working very hard." Xiao Yizi said, "In fact, many times at night, the emperor would secretly go to Gu Qing's study to read Gu Qing's book. The emperor always said that if Brother Gu Qing taught Di Renjie, he would often sneak to Gu Qing's study at night. Gu Qing's books are very profound, and some things need to be understood very obscure, and some words are not known to you."

"Is Gu Qing's study very mysterious?" Gao Yang was puzzled. Gu Qing's laboratory was mysterious. Gu Qing's study always had the door open. What's so mysterious?

Little Shizi glanced around and whispered, "Does the emperor know what psychology is?"

"What?" Gao Yang was puzzled.

"According to the emperor, this psychology is a very terrible science. It is said that you can know what others are thinking." Little Rice whispered, "Is it amazing if you know what others are thinking."

"Well, but it's a bit heartbroken." Gao Yang nodded.

"In fact, psychology was also copied by my husband." Wu Mei walked into the room.

"Ah! Sister Wu Mei!" Little Shizi said in surprise and whispered that she was found blushing.

"Actually, psychology is not that scary." Wu Mei said to Gao Yang and Xiao Aizi, "It's just a way to take advantage of human psychological changes."

"Crossed?" Gao Yang was puzzled, "Where did he copy it?"

"I have been with Gu Qing since I was a child. I know some secrets. As for what I can't say for the time being, you will know in the future." Wu Mei smiled and said, "My husband always said that his knowledge can beat all the masters of the Tang Dynasty, but many books were copied and left aside and too lazy to read them."

"He is such a virtue, lazy!" Gao Yang also smiled.

Li Zhi stood in front of the bookshelf of Gu Qing's study. He had heard that Gu Qing could make electricity before, but he didn't know what the principle was. Gu Qing didn't have many books, most of which were written by Gu Qing and Wu Mei. Gu Qing's calligraphy also made these books look particularly laborious, especially the new characters used by Gu Qing. No one can recognize them except Gu Qing and the book. Even this book is full of new characters, which even Di Renjie can't understand. The shape of the characters is somewhat similar to the current text, but he still can't read them, but he only knows some of them.

Perhaps Gu Qing plans to teach his children, but no one has any unique skills, so Gu Qing will leave it to his children.

Li Zhi took a book, which is a high-level physics. The students of the academy have not learned this knowledge yet. There should be knowledge about magnetic fields on it. When they opened the book, they read it. The handwriting on it was very beautiful. You can tell at a glance that it was not written by Gu Qing. Most of the books here were written by Wu Mei.

As soon as he sat down to read a book, Li Zhi became distracted. Where did Gu Qing come from? His new character has the shadow of Tang Wen, but no one or any dynasty has used Gu Qing's words since ancient and modern times.

A few drops of rain fell, and Gu Qing was interrupted by the cold rain, so he had to get up and go into the house.

Seeing Li Zhi in his study, Gu Qing walked in lightly, "What is Your Highness King Jin looking at?"

Hearing the voice, Li Zhi looked up at Gu Qing, "If you don't tell me, I have to learn it myself."

"Actually..." Gu Qing spoke.

"Hmm?" Li Zhi saw Gu Qing about to say, and his eyes began to look forward to it.

"Your Highness King Jin should learn it yourself." Gu Qing smiled and turned around and left.

Li Zhi furiously closed the book, "Gu Qing, do you have to tease me like this? It's too much."

At the dinner table, Li Zhi was eating very fiercely, and biting the chicken legs in one bite, as if he was venting something.

"His Highness King Jin is eating slowly." Gu Qing looked at Li Zhi's appearance and put a basin of fried chicken legs in front of him, "What else is there."

Li Zhi picked up another chicken leg and bit it.

After the meal, the rain began to drizzle. Gu Qing and Li Zhi sat under the eaves and watched the rain scene. After the meal, a cup of strong tea relieved the greasiness. The two of them took a sip of hot tea and breathed comfortably.

"Gu Qing, you make such a big time every day. I found that you can earn a fortune without doing anything." Li Zhi said for you.

"I am lazy and leave a lot of things to others." Gu Qing said, "I have a lot of resources in my hands. I am willing to give benefits to others. They will do things for me. Your Highness, King of Jin, must understand that if you want others to follow you loyally, the best choice is to make others surrender from time to time, but to tie others to your interests."

"It's like Xiang Yu conquered the Qin Dynasty, or was plotted by Liu Bang, and was beaten to pieces by Han Xin." Li Zhi said slowly, "Is this the reason? Xiang Yu just suppressed others. Those who were kings were just doing nothing. Once the world was in chaos, they would bite Xiang Yu, because Xiang Yu and they had no interests. At most, they would just do their own affairs, right?"
