(2-in-1 chapter)

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

Near evening, Li Zexuan went to the county government again, and saw that He County Commander was organizing the officials of the county government to discuss the plan for repairing the canal, so he sat down and listened quietly.

In his previous life, he was a rural baby, and their village would pump water from the river into the canal in the summer, so he still had some experience in this area. And when he was a child, he would often run to the canal in front of the door to play in the water, for which he also suffered a lot of beatings!

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

So, come to think of it, the best way to do it is a waterwheel!

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

When He Xianling heard this, he finally couldn't help but ask the question in his heart.

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

Li Zexuan smiled slightly: "Don't hide it from you, Ben Hou is making people make a kind of overturned car that can rely on water power or animal power to transport water, Ben Hou calls it a water wheel, it can carry water from low to high places day and night, and this thing has been initially formed, and after the test is passed tomorrow, it can be quickly mass-produced, and then you can pass through it and lead the water in the Bahe Dam to various Zhuangzi!" ”

"What? Is there such an amazing tool in the world? It's incredible~! ”

Hearing this, He Xianling couldn't help but exclaim.

The rest of the people were also full of shock, although everyone thought it was incredible, but no one doubted the truth of what Li Zexuan said, mainly because Li Zexuan had created too many miracles before, and in their minds he had become an omnipotent god~!

Li Zexuan said lightly: "This is nothing strange, you just need to plan the channel direction of each village according to Benhou's intentions, as for the manufacture and placement of the waterwheel, Benhou will order the craftsmen to go and do it well!" ”

"Yes! Hou Ye~! ”

Everyone hurriedly surrendered their orders.

Li Zexuan thought for a while, and then ordered: "In addition, the third class of officials will be recruited as soon as possible, and after the canal is repaired, the county government must begin to rectify the public security environment in the city, and then the Department of Commerce will also be established, which is related to the development prospects of Lantian County, and you must pay attention to it!" ”

"Oh~!"

....................................

The Royal Palace, the Hall of Ganlu.

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

After reviewing the recital, Li Erban leaned on the dragon couch and asked a little tiredly.

"Back to Your Majesty, as far as the old slave knows, Yong'an Hou has already handed over the drawings to the workshop yesterday, and this afternoon, the workshop has already built the skeleton of the waterwheel! It seems that in the afternoon of the day after tomorrow, the launching test will begin~! ”

Zhao Song knew that Li Er's heart was still in the drought recently, so he asked his subordinates to pay more attention to the manufacturing progress of the waterwheel, so that as soon as Li Er asked this, he could answer it immediately!

"Oh? So fast? ”

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

Zhao Song smiled slightly: "Your Majesty doesn't know, Yong'an Hou has recruited many excellent craftsmen with extremely generous conditions this year, and now the new workshop of the Strange Pavilion is far more than ten times larger than before, and there are thousands of craftsmen, even the general supervisor and the Ministry of Works can't compare with it, so if Yong'an Hou wants to make a thing with all his might, the speed is definitely the fastest in the world!" ”

When Li Er heard this, he couldn't help but laugh and said, "Heh! If this kid does this, it is estimated that those masters who will be in prison will run to him after resigning, right? Isn't this the talent that robbed me? ”

Although he said this, Li Er's tone did not sound angry.

Zhao Song couldn't help but smile and said: "Yong'an Hou is determined to carry forward engineering, so the scale of his workshop can be so huge, Your Majesty is broad-minded and can accommodate hundreds of rivers, so Yong'an Hou's learning can be useful!" ”

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

"In the afternoon of the day after tomorrow, if the waterwheel really wants to start the test, remember to remind me when the time comes, and I will go and see it!"

After a moment of silence, Li Er suddenly spoke.

"Yes! Your Majesty! ”

……………………………………

The next day, early in the morning.

The officials of the county government of Lantian County, under the command of He County, went out 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, and today the yagongmen all brought the task book and a drawing, and each person was responsible for a Zhuangzi.

Of course, not only the officials, but Li Zexuan also sent craftsmen to Zhuangzi to guide the villagers to build cement ditches.

Before the sun rose, the farmers began to dredge the ditches under the command of the officials and craftsmen in their own villages, carrying shovels!

In the afternoon of the same day, next to the Bahe dam, one after another high brackets began to be built, each bracket was more than a zhang high, and on this row of brackets, a wooden rectangular tank about three feet wide was installed.

The craftsmen climbed the ladder and banged on it, and the sound of "bang" was endless.

"Young master, the places with gaps in the joints of the wooden planks on this sink are all smeared with tung oil, so as to ensure that there will be no leakage on it! After today, the tung oil on it should be dried, and tomorrow we will start the test, when the time comes to open the gate on the east side of the dam, we will place the waterwheel on the river below the dam, and then see if the waterwheel can lift the water in the river to the top of our heads! ”

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

Li Zexuan nodded approvingly: "Hmm! In terms of details, you have thought very carefully, otherwise with my few drawings, I would not have been able to build a waterwheel that can really be put into practice! ”

This is true, working with the old craftsman can often save a lot of trouble, some problems even if you have not thought of it, have never been mentioned, but the old craftsman can help you notice. This is experience, and it is a careful habit that has been cultivated over many years!

Fauber laughed and said:

"Huh! What did the young master say? If it weren't for your idea and your drawings, this watermill wouldn't be there yet! The old man has been a craftsman all his life, but he has more experience than the young master, but when it comes to invention and creation, the young master has thrown the old man for more than ten streets! ”

"Haha! We're all family, so don't brag about each other! Fauber, this sun is still quite poisonous, you should go back and rest first! This side is taken care of by me and Mr. Mo, and there will be no problems. ”

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

Fu Bo is a person who does not accept the old man in his bones, and when he heard this, he hurriedly retorted: "Young master, the old man is not so weak, bask in the sun, it will be fine......"

Li Zexuan directly interrupted Fu Bo's words and said, "Fu Bo, 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, what the mountain chief said is right, this weather is very hot, your old body is important!" Let's go back and rest! ”

"Oh well! Young master, Brother Mo, if there is anything, just send someone to find the old man! ”

Fauber couldn't help it, so he had to leave alone.

Li Zexuan and Mo Huai took on the role of supervisors and began to patrol the construction site by the Bahe River.

"Mr. Mo, I heard that you have been taking the teachers of the Physics Department of the academy to study the construction of the hydropower station on the dam recently, how is the progress now?"

Li Zexuan suddenly remembered something and asked.

Bahe Hydropower Station is the first killer project of Yanhuang Academy, its practical significance and symbolic significance are very significant, Li Zexuan also said at the beginning, encourage all teachers of the Department of Physics, Mathematics and Chemistry to actively participate in it, on the one hand, it is to confirm what they have learned in daily life, on the other hand, they can also get the corresponding contribution degree and use it for future evaluation titles!

In the past few days, in addition to assisting Fu Bo in making waterwheels, Mohuai has spent most of the rest of his time on the research of hydropower stations, which can be described as conscientious, making Li Zexuan, the head of the mountain, a little ashamed of himself!

Mo Huai heard Li Zexuan's question, thought about it, and replied:

"Yamaga, we have determined the location of the generator, as well as the layout of the control lines, and when the water wheel is busy and the dam is opened to release water, we plan to install the generator and generator blades to see if we can generate electricity!" This way, we don't waste the water in the dam and we can test if our generators are working! ”

Li Zexuan nodded and said, "That's fine!" After all, practice makes true knowledge, and 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 an electrical appliance to verify, before that, I will help you make the light bulb~! Oh yes! You still have to make transformers, electromagnetic relays, etc., these supporting facilities, you have to start preparing now! ”

Light bulbs, transformers, electromagnetic relays, these professional terms are all in physics textbooks, and Yi Mohuai did not show surprise because of these new words, he was surprised that Li Zexuan wanted to make a light bulb!

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

Mo Huai was surprised and asked a little incredulously.

Li Zexuan nodded and said, "I have a way to make a light bulb, I originally planned to build it a while ago, but at that time, I was entangled in everything, and it was too late, so I recently took the time to make a few to try the effect!" ”

When Mo Huai heard this, he immediately said excitedly: "That's really good! Mo has only seen this thing in the textbook you wrote, but he has never seen the real thing! You say in your book that with this thing, you don't need to light oil lamps or candles at night, because the 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 the real light at night, and the county seat of Lantian County can become a city that never sleeps!" ”

..............................

Following.

After two days of hard work by the craftsmen, the waterwheel, the brackets, sinks and other parts that matched the waterwheel were finally installed near the downstream surface of the Bahe dam.

It is said that since the construction of the dam of the Bahe River was completed and the sluice gate was closed for storage, the water level of the downstream river surface has become shallower and shallower day by day, so the place where the waterwheel is placed, the height of the bank from the water surface is as much as one or two feet, thanks to the waterwheel, otherwise even if a ditch is dug from here, the river water is estimated to not flow out!

"Young master, the waterwheel is in place, but the water level of the downstream river is too shallow, and the river water has almost no flow speed, so the waterwheel is not rotating, should we open the gate now to release the water and let the downstream river flow?"

Fauber came over at this time and asked.

Li Zexuan pondered for a moment, and then said:

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

"Hmmm! Then the old man will give orders! ”

Fauber answered, and went down!

"Huh! At such an important moment, you kid didn't even 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 only Li Er, but also Fang Xuanling, Eldest Sun Wuji, Wei Zheng, Cheng Yanjin, Qin Qiong, Niu Jinda, and other Li Er's henchmen and courtiers, all of whom came!

Such a battle can startle the craftsmen on the construction site, and they bow down one after another.

"Your Majesty!"

Li Zexuan also hurriedly bowed to Li Er.

Li Er first said to those craftsmen: "You don't need to be polite, what should you do or what you should do, just treat it as if you didn't see me!" ”

Then, he looked at Li Zexuan again and said, "Okay, you can also be exempted!" Scold! This is what you call a waterwheel? ”

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 but be a little surprised.

Cheng Biting Jin, Wei Zheng and other important ministers also widened their eyes and stared at that direction.

"Back to Your Majesty, this is the waterwheel, after a while the gate is opened and the water flows and the river flows, the waterwheel will turn, and the river will be carried into the tank above our heads!"

Li Zexuan arched his hand.

"So tall?"

Li Er looked up at the sink above, couldn't help but raise his eyebrows, and then said, "Then you can let people open the gates!" I'm going to see if this thing can move the river and carry water today! ”

"Oh~!"

Li Zexuan gave up his hand.

"Open the gates~!"

After a while, the dam came to the shout of Mohuai, followed by a loud "boom", only to see a gate of the dam opened, the river water in the dam rushed out, fell on the downstream river surface stirred up snow-white waves, because the location of the waterwheel is not far from the dam, so although only one gate was opened, but the location of the waterwheel, the flow rate of the river is still relatively turbulent!

So, under the watchful eyes of everyone, the huge roulette wheel finally began to spin, and it turned faster and faster!

The inverted bucket on the outer outline of the roulette wheel, with a bucket of river water, poured out at the top of the roulette head, and suddenly, the sound of water flowing sounded in the sink~!

"Out of the water~! Out of the water~! ”

At the other end of the sink, a craftsman was taking care of it, and after a while, the cheers of the craftsmen rang out from there.

The ministers were shocked, and Li Er also felt incredible!

"Moving rivers and transporting water, this is a heavenly waterway! It's like a miracle~! ”

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