Yang Xiancheng and Shen Zhushu can be counted on to do things. Pen? Interesting? Pavilion wWw. ｂiquge。 Although Liu County Lieutenant has never had any corruption or the like, breaking the law, or oppressing the people, he is a little cheating and tricky when he does things, and he is always unwilling to do his best.

Therefore, Xia Hongsheng entrusted the affairs of the county government to Yang County Cheng and Shen Zhushu.

The first draft of the new commercial law and the new tax law is about to be completed, and Xia Hongsheng needs to go through it again from beginning to end behind closed doors, and check and fill in the gaps for the last time before presenting it to Li Shimin.

Xia Hongsheng temporarily handed over the affairs of the county government to Yang Xiancheng, gave another instruction to his family, and then went into the academy's own office.

Qi Yong called Xia Hongsheng for three meals a day, Xia Hongsheng hurriedly swallowed a few bites, and then continued to sit in front of the desk. When you feel sleepy and can't hold on, you can lie down directly on the back bed to take a nap for a stick of incense, and then get up and continue to watch, day and night.

In order not to let himself rest for more than a stick of incense, Xia Hongsheng also made a simple "alarm clock" - asked Qi Yong to pick up two bricks and stones, one tied a thin thread, fell from the side of the table next to the bed, and put a small gong underneath. Then put another piece on the table, let the string rest on it, and at the other end of the string, wrap a few books, and fall down to hang on the surface. Put a stick of incense on the table, and when you sleep, you will burn it, and when the incense is almost burned, it will burn to the rope, and the thin string will be burned, and a few books will fall on your face, and the masonry on the other side of the table will fall on the little gong, which will make a sound, and alarm yourself, so that you can wake up.

More than half a month has passed, and it will be the end of the first month in a few days.

More than half a month of busyness and exhaustion, coupled with a serious lack of sleep, made Xia Hongsheng startle himself when he looked in the mirror.

Then he laughed again, maybe this son will lead the trend of smoky makeup in Datang.

Shaking his head and smiling, he realized that he hadn't breathed the fresh air outside for more than half a month, so he turned around and happily opened the door and walked out.

"Childe?" Qi Yong was waiting outside the door, and when he saw Xia Hongsheng coming out, he asked.

"Didn't I let you rest for a while?" Xia Hongsheng said.

Qi Yong smiled very honestly: "The little one is afraid that the son will not be able to find someone if he has an order." ”

"It's done, and nothing will happen for the time being. Go and rest a little longer. Xia Hongsheng said: "I went out for a walk, and I haven't moved for a few days. ”

Qi Yong shook his head: "The little ones follow the son, and the little ones are not tired." It's Childe, who hasn't had much rest these days. ”

"Take a walk and rest." Xia Hongsheng said.

The two went down, and Xia Hongsheng wandered around the academy.

The scale of the academy is even larger, since the construction of the academy, the third phase of the project has been completed so far, and now it has covered an area of 3,478 acres, and after the completion of the subsequent phases of the project, this area will be much larger.

It is precisely for this reason that almost eighty percent of the money earned by Xia Hongsheng's entire industry in recent years has been invested in Jingyang Academy.

After strolling around, I walked to the side of the river that flowed from Jingyang Academy. There is a tributary of the Jing River that flows through it, which also became the source of water in the Jingyang Academy.

The huge water wheel on the river makes a lot of sound of water, and next to it is a workshop, where everything that needs to be made with great force is carried out with the power of a waterwheel.

Seeing a few people standing on the bank of the river not far from the waterwheel from a distance, Xia Hongsheng's eyes were sharp, and he saw Li Tai in the middle of several people at a glance.

Seeing a few people talking and pointing at the waterwheel, Xia Hongsheng was curious, so he walked over.

"Meet the Chief!" Several students saw Xia Hongsheng coming, so they bowed and saluted.

"What are you doing pointing at the waterwheel?" Xia Hongsheng waved his hand to signal that they didn't need to be polite, and then asked with a smile.

"Back to the mountain, the students are discussing how to make the waterwheel more energetic." One of the students replied.

Xia Hongsheng smiled and asked again, "How did you discuss this?" ”

"Master, that's it!" Li Tai said to Xia Hongsheng: "A few days ago, Mr. Le came to make things, tried it, but failed to make it, saying that the strength of the waterwheel is still too small. He also said that he could try to build a dam on it, and if he needed a lot of strength, he would block the dam and start to collect water, and when the water had gathered too much, he would open an opening the size of a door in the dam. And the water shall be squeezed out of the mouth, and it shall be turbulent. The water is turbulent, and the force rushing to the waterwheel is greater, and the strength of the waterwheel is greater. The students thought about it and felt that what Mr. Le said was very reasonable. I thought I would make a small one like a waterwheel, and then go to the sand to experiment with it. The students were observing the structure of the waterwheel. ”

Xia Hongsheng couldn't help grinning, increasing the speed of the water flow, thereby increasing the strength of the water flow, and then the strength of the waterwheel driven by the water was greater, and the power provided was more. That's a clever idea.

Seeing that several people wanted to experiment on this, Xia Hongsheng's heart suddenly moved, so he said, "Then you don't have to experiment." This is certainly true. We've learned that the faster you are, the more powerful you are. The more water accumulates, the greater the pressure. The smaller the door opens, the faster the water will surely be pressed out of the door at a great speed under the strong water pressure. The speed of the water that is pressed out must be faster, and the force must be greater. However, it has not occurred to you to try another way to bring more power than water without using water? ”

"What else can be more powerful than the rapids? Even if there is, I'm afraid I can't use it with the waterwheel," a student wondered, "Please also ask the mountain chief to teach the students to know." ”

Xia Hongsheng smiled and spit out two words: "Steam!" ”

"Steam?" Another student thought for a moment and said, "The student remembers that steam is a gaseous form of water, and water will evaporate into gas, and if it is heated, it will quickly evaporate and turn into a gas. The most common is the smoke that comes out of the water when it is boiled, which is water vapor. The mountain is long, but how can this water smoke and steam have so much strength to surpass the waterwheel? ”

"Go find a kettle and get a cork ping pong ball!" Xia Hongsheng thought for a while and said to them.

Several students were immediately overjoyed, and hurriedly spread their legs and ran away.

"Get it quickly, and the teacher will be waiting for you in the watermill room." Xia Hongsheng looked at the few students who quickly ran to get things, and shouted at their backs with a smile.

Although he didn't know how to make a steam engine, he wasn't smart enough to invent a steam engine himself. It doesn't mean that among so many students in the academy, there is no smart person.

As long as you understand the principle and have the spirit to continue to explore deeply, you will be able to invent it one day. (To be continued.) )
