(two-in-one chapter)

"The source of the main channel of each Zhuangzi must be at the highest position, so as to ensure that the river water can flow to all the fields in the village!"

As the evening approached, Li Zexuan went to the county office again. Seeing that the county magistrate was organizing the officials of the county office to discuss the plan for repairing the canal, he sat down and listened quietly. holding a map, said.

In his previous life, he was a rural child, and in the summer they would also pump water from the river into the canal, so he still had some experience in this regard. Moreover, when he was a child, he would often go to the canal in front of the door to play with water, and he was beaten a lot for this!

It's just that at that time, water pumps were used to pump water. Where would he go to get a water pump in this era? He understands the principle of the water pump, and if you ask him to do it now, he will do it, but the water pump is either driven by electricity or diesel, and he can't provide these two energy sources now!

So, after much deliberation, the best solution is the waterwheel!

"Master Hou, if the source of the main channel of each Zhuangzi is placed at the highest position, how can the water be led up?"

Hearing this, Magistrate He finally couldn't help but ask the question in his heart.

This is a question that everyone in the house wants to ask but dare not ask.

Li Zexuan smiled slightly and said: "To tell you the truth, this lord is making a rollover car that can rely on water or animal power to transport water. This lord calls it a waterwheel, which can carry water from low places to the ground without interruption day and night. The high place, and this thing has already taken shape, after passing the test in the future, it can be mass-produced quickly, and then it can pass through it and lead the water from the Bahe dam to each Zhuangzi!"

"What? There are such amazing tools in this world? It's incredible~!"

Hearing this, the county magistrate couldn't help but exclaimed.

The rest of the people were also shocked. Although everyone thought it was inconceivable, no one doubted the truth of what Li Zexuan said. An omnipotent goddess~!

Li Zexuan said indifferently: "This is nothing surprising. You just need to plan the channels of the villages according to Ben Hou's wishes. As for the manufacture and placement of waterwheels, Ben Hou will order the craftsmen to do it!"

"Yes! Lord Hou~!"

The crowd hurriedly handed over their orders.

Li Zexuan thought for a while, and then instructed: "In addition, the three classes of yamen should expand their recruitment as soon as possible. After the canal is repaired, the county government must start to rectify the public security environment in the city and the square, and the Commerce Department will also be established at that time. This is related to Lantian County. Development prospects, you must pay attention to it!"

"Hey~!"

…………………………

Palace, Nectar Palace.

"What's going on with Li Zexuan? Didn't he say he was going to build a waterwheel? How's it going now?"

After reviewing the memorial, Li Erban leaned on the dragon couch and asked tiredly.

"Go back to your majesty, as far as the old slave knows, the Marquis of Yongan had already handed over the blueprint to the workshop yesterday, and the workshop had already built the skeleton of the waterwheel this afternoon! It seems that the next afternoon will begin. The water test is done~!"

Zhao Song knew that Li Er was concerned about the drought in the people recently, so he asked the servants to pay more attention to the manufacturing progress of the waterwheel. Therefore, when Li Er asked this question, he could immediately answer it!

"Oh? So fast?"

Li Er raised his brows in surprise and said in surprise.

Zhao Song smiled slightly: "Your Majesty does not know, the Marquis of Yongan has recruited many excellent craftsmen with extremely favorable conditions in the past year, and now the new workshop of Qiqu Pavilion is more than ten times larger than before, and the craftsmen are all There are thousands of people, and even the general supervisor and the Ministry of Industry can't compare with them, so if the Marquis of Yongan wants to build something with all his strength, the speed is definitely the fastest in the world!"

Hearing this, Li Er couldn't help laughing and said, "Oh! This kid is doing this. It is estimated that the master craftsmen who will be the prisoners will run to him after resigning? Isn't this the talent who robbed me?"

Although he said that, Li Er's tone did not sound like he was angry.

Zhao Song couldn't help laughing and said, "Yongan Houzhi is promoting engineering, so his workshop is so large. His Majesty has a broad mind and can accommodate hundreds of rivers, so what Yongan Houzhi has learned can be useful!"

Li Er shook his head, but didn't say anything, but the light smile at the corner of his mouth proved that Zhao Song's flattery was very useful in Lao Li's heart!

"In the afternoon of the day after tomorrow, if the waterwheel can really start the test, remember to remind me at that time, and I will go to see it too!"

After a moment of silence, Li Er suddenly spoke.

"Yes! Your Majesty!"

………………………………

The next day, early morning.

Under the orders of the magistrate He, the yamen of the Lantian county government dispatched their entire nests and went to the villages to direct the construction of cement ditches.

As for the tasks assigned by each Zhuangzi, they had already been assigned last night. Today, the yamen clerks brought the task book and blueprints, and each person was responsible for one Zhuangzi.

Of course, not only the yamen, but also Li Zexuan sent craftsmen to go to Zhuangzishang to instruct the villagers to build cement ditches.

Before the sun rose, the villagers carried shovels and began to clear the channels under the command of the yamen and craftsmen in their own villages!

In the afternoon, next to the Bahe Dam, one after another high brackets began to be built.

The root bracket is more than ten feet high, and on this row of brackets, there is a wooden rectangular sink about three feet wide.

The craftsmen climbed the ladder and tapped on it, and the sound of "bang bang" could be heard incessantly.

"Master, all the places with gaps at the joints of the wooden boards on the sink are covered with tung oil, so as to ensure that there will be no water leakage on it! After today, the tung oil on the top should be dried, and we will start the test tomorrow. It's time to open the gate on the east side of the dam, and we will place the waterwheel on the river below the dam, and then we'll see if the waterwheel can lift the water in the river to the top of our heads!"

Uncle Fu personally took Li Zexuan to inspect the "construction site", and while inspecting, he also explained to Li Zexuan.

Li Zexuan nodded approvingly and said, "Yeah! Uncle Fu, you are very thoughtful about the details. Otherwise, just relying on my few drawings, you can't make a waterwheel that can really be put into practical use!"

This is the truth. Cooperating with old craftsmen can often save a lot of trouble. Even if you have never thought of and never mentioned some issues, old craftsmen can help you notice them. This is experience, and it is a careful habit that has been cultivated over many years!

Fu Bo laughed and said:

"Haha! What did the young master say? If it weren't for your ideas and drawings, this waterwheel would definitely not have been seen by now! The old man has been a craftsman all his life, but he has more experience than the young master, but when it comes to inventions and creations, young master, you But it's more than ten streets to dump this old man!"

"Haha! We are all a family, so don't brag about each other! Uncle Fu, the sun is still quite poisonous, you should go back and rest first! Mr. Mo and I will take care of this place, and there will definitely be no problem. "

Li Zexuan felt that the weather was a little hot, so he comforted Fu Bo.

Uncle Fu was a man who was deeply dissatisfied with the old man. Hearing the words, he hurriedly retorted: "Master, the old man is not that weak, just basking in the sun, nothing will happen..."

Li Zexuan interrupted Uncle Fu directly and said, "Uncle Fu, don't insist on it when you are old. If you suffer from heat stroke again at your age, then my sin will be too great!"

Mo Huai also echoed: "Brother Fu, the mountain chief is right, the weather is very hot, and your health is important! You should go back and rest soon!"

"Alright then! Young Master, Brother Mo, if there is anything, just send someone to find this old man!"

Unable to resist, Fu Bo had to leave alone.

Li Zexuan and Mo Huai acted as supervisors and began to inspect the construction site by the Bahe River.

"Mr. Mo, I heard that you have been taking the teachers from the physics department of the college to study the construction of the hydropower station on the dam. How is the progress now?"

Li Zexuan suddenly remembered something and asked.

The Bahe Hydropower Station is the first killer project of Yanhuang Academy, and its practical and symbolic significance is very important. Li Zexuan also said at the beginning that all teachers from the Department of Physics, Department of Mathematics, and Department of Chemistry are encouraged to actively participate in it. On the one hand, it proves that What you usually learn, on the other hand, you can also get the corresponding contribution degree, which can be used for future evaluation of professional titles!

In the past few days, Mo Huai has spent most of his time on the research of hydropower stations, besides assisting Fu Bo in making waterwheels.

Mo Huai heard Li Zexuan's question, thought for a while, and replied:

"Shan Chang, we have already determined the location of the generator and the layout of each control circuit. When the waterwheel is busy and the dam is opened to release water, we plan to install the generator and generator blades. Take a look. Whether it can generate electricity! In this way, we will not waste the water in the dam, but also test whether our generator can work normally!"

Li Zexuan nodded and said, "That's fine! After all, practice brings out true knowledge. If we don't do it ourselves, we will never know whether we are right or wrong. In this way, if your generator can generate electricity normally, you need a power generator. Electrical appliances to verify, before that, I will help you make the light bulbs~! Oh, yes! You also have to make transformers, electromagnetic relays, etc., these supporting facilities, you must start preparing now!"

Light bulbs, transformers, and electromagnetic relays are all technical terms in physics textbooks, so Mo Huai was not surprised by these new words. What surprised him was that Li Zexuan wanted to make a light bulb!

"Captain, are you sure you can make a light bulb now?"

Mo Huai was extremely surprised and asked in disbelief.

Li Zexuan nodded and said, "I have a way to make a light bulb. I originally planned to make it a while ago, but at the time, I was so busy with everything that I didn't have time. Recently, I took the time to make a few test results!"

When Mo Huai heard the words, he immediately said excitedly: "That's really great! Mo has only seen this thing in the textbook you wrote, but he has never seen the real thing! You said in the book that there are With this thing, there is no need to light oil lamps or candles at night, because this light bulb is dozens of times brighter than those things!"

Li Zexuan said with a smile: "The electric light is indeed a good thing. With it, people can find real light at night, and it is possible for Lantian County to become a city that never sleeps!"

…………………………

the next day.

After two days of hard work by the craftsmen, the waterwheel and its supporting brackets, water tanks and other components were finally installed near the downstream river surface of the Bahe Dam.

It is said that since the completion of the construction of the Bahe dam and the closure of the gates to store water, the water level on the downstream river surface has become shallower day by day, so where the waterwheels are placed, the height of the shore from the water surface is as much as one or two feet. Waterwheel, otherwise even if you dig a ditch from here, the river water probably won't flow out!

"Master, the waterwheel is already in place, but the water level in the downstream river is too shallow, and the river water has almost no flow speed, so the waterwheel does not turn. Shall we open the gate to release the water and let the downstream river flow?"

Fu Bo came over at this time to ask for instructions.

Li Zexuan pondered for a while, then said:

Li Zexuan nodded and said, "Just open a gate and try the effect first!"

"Yeah! The old man will tell you to go on!"

Fubo responded and went down!

"Haha! At such an important moment, you kid didn't know to send someone to inform me!"

At this moment, a familiar voice came from behind Li Zexuan, who else could it be if it wasn't Li Er?

Li Zexuan hurriedly turned around and saw that it was not just Li Er, Fang Xuanling, Changsun Wuji, Wei Zheng, Cheng Yaojin, Qin Qiong, Niu Jinda and all of Li Er's confidants and officials, all came!

Such a battle shocked all the craftsmen on the construction site, and they all bowed and saluted.

"I see you, Your Majesty!"

Li Zexuan also hurriedly bowed to Li Er.

Li Er first said to the craftsmen: "You don't need to be more polite, what should I do or what should I do, just pretend that I didn't see me!"

Afterwards, he looked at Li Zexuan again and said, "Okay, please excuse yourself! Ha! Is this the waterwheel you were talking about?"

At this time, Li Er caught a glimpse of the giant roulette standing on the lower reaches of the Bahe River, and couldn't help being a little surprised.

Cheng Yaojin, Wei Zheng and other important officials also widened their eyes and stared in that direction.

"Go back to your majesty, this is the waterwheel. After the gate is opened and the water flows, the waterwheel will turn and the river water will be transported to the water tank above our heads!"

Li Zexuan arched his hands.

"so tall?"

Li Er looked up at the sink above, couldn't help but raised his eyebrows, and then said, "Then let someone open the gate! Today, I want to see if this thing can transport water in the river!"

"Hey~!"

Li Zexuan took the lead.

"Open the gate~!"

After a while, Mo Huai's shout came from the dam, followed by a loud "bang". I saw one of the gates of the dam opened, and the river water in the dam rushed out and fell on the downstream river. There was a burst of snow-white waves. Since the location of the waterwheel was not far from the dam, although only one gate was opened, where the waterwheel was located, the flow rate of the river was still relatively fast!

So, under everyone's attention, the huge roulette finally started to turn, and it turned faster and faster!

The buckets on the outline of the roulette, with buckets of river water, poured out at the top of the roulette head. Suddenly, the sound of water flow sounded in the sink~!

"The water is out~! The water is out~!"

There was a craftsman at the other end of the sink, and after a while, there were cheers of craftsmen,

The ministers were astonished, and Li Er also felt incredible for a while!

"Moving the river to transport water, this is a waterway in the sky! It's like a miracle~!"

Wei Zheng raised his neck, looked at the sink above his head, and muttered to himself in shock.
