Du Jinning didn't answer, but turned his head and ordered: "Chunhe, you take a few guards to move those things in my Jinghe courtyard, let them be careful, don't break them." ”

Chunhe answered.

Du Jinning turned his head and smiled mysteriously at Zhao Yu: "Brother Huang will know in a while." ”

Guan Lehe looked sweaty.

His own disciples don't regard the emperor as a big official.

Zhao Yu didn't pay attention to these at all. He looked at Qi Muyuan with a curious look, and couldn't help asking, "Do you know what she's doing?" ”

Qi Muyuan shook his head: "Didn't you let her go out during this time?" She recruited two or three craftsmen, and she didn't know what she was doing, and she didn't let me see it. When he spoke, his face was full of helplessness.

Don't even let Qi Muyuan see it?

Zhao Yu became more and more curious about the guanzi sold by Du Jinning.

After a while, Chunhe and a few guards also brought a set of strange things over.

Du Jinning instructed them to put their things in the yard, took the small boat that Chunhe held in his hand, turned his head and smiled: "Let's go to the edge of the pond." ”

Zhao Yu, Guan Lehe, and Qi Muyuan originally leaned over to look at the strange thing, but when they heard this, they turned their heads and looked at the boat in Du Jinning's hand.

The ship was not large, about two feet long and a foot wide, and the workmanship was exquisite, except that there was no mast or sail installed, but a clay pot was placed diagonally in the middle, the mouth of which was plugged with a wooden cork, and a hollow bamboo pipe was inserted into the cork; There is also an oil lamp at the bottom of the clay pot.

Zhao Yu couldn't help asking, "What is this?" ”

"This is a boat that can walk on its own without pulp and sails." Du Jinning said.

Zhao Yu became interested: "Oh, what kind of truth is this?" ”

"You can see for yourself first, and see what you can say."

At this time, the group had already left the main courtyard and arrived at a pond not far from the main courtyard. Although there are many lotus and aquatic plants planted on the edge of the pond, there is a large body of water in the middle, which is enough for small boats.

"Stay here, I'll go down." Du Jinning said.

"Hey, be careful." Qi Muyuan saw that Du Jinning didn't regard herself as a pregnant woman at all, where would she let herself go? Even if there is a maid following him, he is not at ease. had to helplessly support her, and followed step by step.

Du Jinning first lit the fuel lamp with a fire fold, and then put it on the water.

"Hey, why don't you move?" Zhao Yu asked on the steps.

"You have to boil the water in the clay pot first." Du Jinning said.

There was not much water in the clay pot, and as soon as Du Jinning's words fell, the water boiled, and water vapor spewed out from the bamboo pipe. The moment the water vapor erupted, the boat began to move forward.

Zhao met a thirty-year-old person, but he was still like a child, and he shouted excitedly: "It's moving, ah, it's moving by itself." As he spoke, he followed the boat for a short distance. made Gonggong Wu run along, and the helpless expression on his face was the same as Qi Muyuan just now.

However, the steam on the boat was not much at first, and it did not run fast. The power came up in the back, and "whoosh" all at once rushed out far away. Zhao Yu ran a few steps, and he could only watch the boat throw his back.

"How long will it run? Will it turn when it encounters the shore and aquatic plants? He asked.

"Run until the water in the clay pot is dry. If no one is in control, it will naturally not turn. Du Jinning silently added in his heart: If there is a remote control sensor, it can make it turn.

At this time, she missed modern high-tech very much.

Although Du Jinning's answer made Zhao Yu a little disappointed, he was more interested in another device.

"Have someone row over and get the boat back." Du Jinning gave his subordinates a word, and went ashore with the support of Qi Muyuan.

"Let's go back and see the other one."

The group then returned to the main courtyard.

Although there are many dazzling chemical experiments and interesting physical experiments, Du Jinning wants to show steam power today. Watt thought that Watt's discovery of steam power had led to the Industrial Revolution, and she hoped that this would happen in ancient China.

So the device she put in the yard was a little more complicated, but it was still the principle of steam. She had the carpenter make a few gears, which were turned by steam, and at one end of the gear, a small hoe that was constantly waving, was digging a hole there.

Although Zhao Yu no longer emphasizes agriculture and suppresses business, agriculture is the foundation of the country, and the most important thing for any king is agriculture.

The device was wielding a hoe instead of a hammer or something else, and she just wanted to tell Zhao Yu that her experiment was not a novelty, but could be used for national production.

Sure enough, there was no need for Du Jinning to say more, Zhao Yu looked at the small hoe that kept digging pits, and was shocked by the conclusion he had reached.

He turned his head and asked eagerly, "Can you really use this to hoe?" You don't need a cow, you just use water, and you can hoe the ground? "If so, wouldn't vast tracts of wasteland be reclaimed?

Although this statement is very loose, Du Jinning still nodded vigorously and said, "Yes, definitely can." ”

Zhao Yu's eyes were as bright as stars.

"But to do that, there are all kinds of research that needs to be done, and it takes a long process." Du Jinning said the second half of the sentence.

"Don't worry." Zhao Yu took a deep breath with a heroic expression, "As long as I can see this day in my lifetime, I will have nothing to ask for." ”

"You'll see it for sure."

At this moment, Du Jinning was extremely glad that he was a science student. Even though she studied agriculture, she did know a little about the principles of physical chemistry. If she is a scholar of literature, she knows that there is such a thing but she can't touch the edge and can't do it, then it's called depression.

"In addition to this, there is one more thing for the imperial brother to see." Du Jinning said.

"Oh? What the? Zhao Yu's sense of anticipation was simply bursting.

"Please move to the Moon Pavilion."

So the group went to the Deyue Pavilion.

When he arrived at the door of Deyue Pavilion, Du Jinning turned his head and instructed Chimu: "Be careful for a while, don't hurt yourself." ”

"Don't worry, princess, the villain knows." Akagi Road.

Du Jinning and the others went up to the second floor of Deyue Pavilion, and Zhao Yu saw that the little guy who was talking to Du Jinning just now was standing ten zhang away from Deyue Pavilion at this time. Behind him lay a stone the size of a tabletop.

"Brother Huang, teacher, the test is a little loud for a while, but we are far away, there will be no danger, don't panic." Du Jinning said.

She wasn't afraid of scaring Zhao Yu, but she was worried that Gonggong Wu and the guards would make some drastic moves because they were frightened. This sentence was clearly said to Zhao Yu, but it was actually a warning to Gonggong Wu and the imperial guards.

Zhao Yu pointed at Akagi and asked, "Is that there?" ”

"Yes." Du Jinning said.

"It's okay, it's so far away. Your royal brother is not a cowardly man. Zhao Yu made a joke.

Du Jinning didn't say anything more, and gestured directly to Chimu.
