"Your Highness, you don't understand even your humble position."

Li Tai sat cross-legged, looking at the device in the wooden box in front of him, and said: "You go ahead and shake it for me."

"Here."

It was summer in Guanzhong, and the guards listened to King Wei's instructions and took turns shaking the coil.

Not long after, I saw a bear catching a chicken, with a girl sitting on the bear's back.

Seeing Uncle Wei Wang, Xiao Qingqing grabbed the big bear's ear and made it stop catching chickens and walk towards this side.

"You don't have to attend class today?"

"My parents are going to give lectures to my aunts and uncles, so I can go out and play." Xiao Qingqing patted the big bear on the head.

It sat down and sat down.

It took Xiao Qingqing to get off the bear's back.

"Do you understand this?" Li Tai frowned and looked at the magnets and coils.

"can't read."

I wasn't surprised when I heard the reply, she was just a seven-year-old child.

Xiao Qingqing took another closer look and said doubtfully: "Huh? It seems different."

Li Tai turned to look at her again, "What's different?"

Xiao Qingqing frowned and took two steps, "Actually, I saw a blueprint in dad's study. That blueprint was originally used to make a lathe. But then, I don't know what happened, and dad gave up again."

"What's different about that drawing."

When Uncle Wei Wang asked, Xiao Qingqing suddenly stopped talking and stood there with a cute smile on his face.

Li Tai said with a bitter face: "Uncle will make you a roast duck."

Seeing that she still didn't speak, he glared at his guards and ordered: "Didn't you hear that?"

"Here."

The guards left quickly.

After a while, a plucked and cleaned duck was brought over.

Li Tai tied up the duck with iron fibers and put it on the rack to roast, and then looked at his niece.

Then she said: "Actually, Uncle Wei Wang's method is wrong. The drawing I saw at my father's place showed a magnet rotating around a copper wire."

"Huh? The magnet revolves around the copper wire?"

"Well, and the space is not that big." Xiao Qingqing drew on the ground with a wooden stick, drawing a circle and several squares.

Children are not very good at drawing, so she could only rely on her own memory and said: "It's roughly like this."

Several guards around Li Tai also gathered around and looked at it with frowns, trying to find some possibility of enlightenment in this messy painting.

Xiao Qingqing added: "And the space inside is very small. The magnet and the coil are very close, about three inches apart."

Li Tai thought about it, "So that's it."

Xiao Qingqing's eyes were already on the roast duck that was sizzling and smoking on the grill.

Li Tai took the stick and drew on the ground, thinking about what Xiao Qingqing described.

"Well, this is like a roller. Do you need to crank it by hand?"

Xiao Qingqing looked full of anticipation, waiting for the roast duck to mature, with a face that had no time for him to care.

When the roast duck is cooked, Xiao Qingqing puts it into a food box.

Li Tai asked: "Don't you want to eat?"

She picked up the food box and hung it around Xiong Da's neck, "Give it to your brother, otherwise he will complain to his parents."

"You siblings are really..."

"Actually, my brother is very smart."

The two siblings on the mountain are not simple. When I think about it again, I feel that the children taught by the brother-in-law and the emperor's sister are not simple.

The sky in Guanzhong is cloudy and relaxed.

In summer, everything here is lazy, even the bear at home hides under the eaves and is unwilling to move.

Xiao Qingqing opened the food box and said, "Eat."

Xiao Anxin said happily, "Sister, where did this roast duck come from?"

"Uncle King Wei gave it to me."

"Oh, Uncle Wei Wang is so kind."

Xiao Qingqing said helplessly: "Originally, it's not for you to eat."

Xin Xin'an added: "My sister is also very good to my brother."

She looked towards the courtyard. She never got tired of seeing Huaqing Pool. She still liked it in winter.

Huaqing Pool will not freeze in winter, and the pool water will emit white smoke in the cold winter, just like a fairyland.

In summer, it has no waves and no white smoke. It looks ordinary, just like the Weishui River outside.

In Chang'an City, in the imperial palace, Li Shimin was playing with a screw, repeatedly sliding the nut in and out of the screw.

"How long have Yuan Tiangang and Li Chunfeng been going to Lishan?"

"Your Majesty, the two Taoist priests went to Lishan Mountain in winter and have not returned yet."

Li Shimin nodded, his eyes fell on the copper screw, and asked again: "What are they doing?"

Li Junxian replied: "Taoist Master Yuan has been searching for the secrets of heaven and earth recently. There are many Taoists in various places in the Central Plains. They look at the sky and water and soil. Whenever they have records, they are sent to Lishan Mountain."

"What are they going to do?"

"I will go to Lishan Mountain to inquire."

Li Shimin put down the screw in his hand and said, "No need, that is Taoist Yuan's lifelong pursuit. It would be great if Zhang Yang could give you some advice."

"Haha." He chuckled and said, "I know Zhang Yang wants to tell the world that the earth is round, but there are still many people who don't believe it."

"Your Majesty, I have heard about those who climbed Mount Tai. When they stood on the top of Mount Tai, they looked at the earth differently than usual."

The Wude Palace was quiet. Seeing that His Majesty stopped talking, Li Junxian bowed and saluted, "The general has made a mistake."

Li Shimin waved his hand and said: "It doesn't matter, you didn't do it unintentionally."

"The general is willing to accept the punishment."

Last year, there were still many people debating whether Mount Tai should be enshrined. This year, these voices have disappeared. Even the government and the public are unwilling to mention Mount Tai again.

The eunuch outside the palace walked over in small steps and bowed: "Your Majesty, Yan Lide is here."

Li Shimin put ice cubes into the wine bowl filled with grape wine, nodded and said, "Let him in."

Yan Lide is the younger brother of Yan Liben.

The Yan family comes from the Yan family in Henan, and the family's inheritance is craftsmanship and painting skills.

Passed down from generation to generation, Yan Liben concentrates on craftsmanship, and Yan Lide hopes to pass down poetry and calligraphy to his family.

Yan Lide looks very similar to his brother, but looks thinner.

Li Shimin handed over a bowl of grape wine.

He took it with both hands and bowed, "Thank you, Your Majesty."

"I know that you are obsessed with poetry, calligraphy and painting, so I feel wronged by letting you take Yan Liben's place."

Li Shimin smiled and said, "Look at this."

The screws and nuts were placed in front of Yan Lide.

He looked at it for a long time and said, "This thing doesn't look like much at first glance."

Li Shimin took a sip of grape wine and said with a smile: "Recently, Guanzhong has harvested a lot of grapes. After we go back, the Western Regions will also pay a lot of tribute. You can take some back with you when you leave."

"Thank you, Your Majesty."

"Can you see anything about this thing?"

Yan Lide stared at the thread for a long time and replied: "Your Majesty, is this thing from Lishan?"

Li Shimin nodded.

"If the Ministry of Industry were to cast it, they would never be able to achieve this level of craftsmanship. These grooves are made very neatly."

Yan Lide took a breath and asked, "How was this thing polished?"

Li Shimin smiled again, "The Marquis of Lishan County said that he had created this thing, so he presented it to me, saying that this thing could help Lishan's casting skills to a higher level, but I haven't understood its use yet."

Yan Lide tried the screws and nuts, and said in a low voice: "Mortise and tenon... hmm? It's really strange, why are they made like this."
