The new army cleared the land and plowed the land. However, after the seeds were planted, it did not rain for ten days and half a month. The sun hung overhead every day, and the seeds that were sown were sown were not to mention germinating, and they were all dried to death. Scarface was so anxious that he ran over and asked Li Zhiyun what to do?

What to do? Chilled salad! In addition to fighting drought and protecting moisture, Li Zhiyun has no other way. Zhang Zheng on the side pointed to the east with his hand and said: "A few days ago, I went to walk on a horse, and I saw a small river at the foot of the mountain over there, and the river surface is also wide, and you can carry water to water the ground. It's just a bit far away, and the brothers are going to suffer from this poisonous sun! ”

Li Zhiyun looked at him and said, "Can you open a canal and bring water over?" Zhang Zheng shook his head and said, "I'm afraid not, the water level of that river is lower than the terrain on our side." Li Zhiyun thought for a while and said, "Let's go over and have a look." ”

Li Zhiyun asked the guards to lead the horses, and several people rode on their horses and went east, traveling seven or eight miles, and came to a small river. Li Zhiyun turned over and dismounted, stood on the bank of the river, and saw that the river was abundant and the water flow was turbulent, but the river level was indeed relatively low, and it was definitely not possible to open a canal to divert water.

Li Zhiyun stood there and looked at it for a while, and suddenly a flash of inspiration flashed in his mind, and he shouted: "Yes, you can build a waterwheel to carry water!" The scarface next to him looked surprised: "What is a waterwheel?" Li Zhiyun smiled and said, "You'll know later." ”

Back in the tent at the station, Li Zhiyun asked people to find pen, ink and paper, lay on a table made of wooden boards, and began to draw drawings of the waterwheel. The waterwheel is also called the tube car, the sky car, the bamboo car, the water wheel of the waterwheel stands upright in the water by the river, and a number of bamboo tubes are obliquely installed around the wheel, and there are as many as 42 pipes. The bamboo tube plays the role of an impeller, using the water flow to push the main wheel and make the waterwheel rotate. The radius of the outer ring where the bottom of the cylinder is located is greater than the inner ring where the cylinder mouth is located, because the two are concentric circles, so when it is low, the bamboo tube holds water (the cylinder mouth is higher than the bottom of the cylinder), and when it is high, the bamboo tube discharges water (the cylinder mouth is lower than the bottom of the cylinder).

This kind of waterwheel is more common in the countryside of southwest China, Li Zhiyun traveled to Guizhou, Yunnan Province in his previous life, and saw a waterwheel. He studied science and engineering, and he has always been very interested in mechanical devices, and he squatted next to him for a long time to study and figure out the principle of the waterwheel, and he still has an impression in his mind at this time.

As soon as Li Zhiyun finished drawing the drawings, Aunt Ying walked in with the food and said, "Lord Wang, it's time to eat." He hurriedly put away the pen, ink and paper and set it aside to make room for it. Ying Gu put the tray on the wooden board, Li Zhiyun snorted, and said, "What is delicious?" It smells so good! Yinggu smiled: "I went up the mountain to pick mushrooms, put some minced meat, and made a bowl of mushroom soup." You taste it, it's fresh! Li Zhiyun picked up the chopsticks and wiped them on his sleeve, and said, "You can also sit down and eat." ”

"I've eaten outside." Ying Gu said, picked up the drawings and looked at them, "Lord Wang, what is this big wheel for?" ”

"It's used to carry water."

"Carrying water?"

"Oh, it's to lift water from low to high."

"Can that be done?"

"Of course it can be done!"

After the drawings were drawn, Li Zhiyun handed the drawings to Scarface and asked him to find someone to make them quickly. There was no shortage of craftsmen in the new army, that is, ordinary soldiers, as long as they were born in a village family, they could also do a little carpenter work. It is impossible for the Zhuang family to pay for everything, and they usually have to build a house and repair the house, build a chicken coop, build a pigsty, make a table and bench, etc., and have to do it themselves.

Scarface found dozens of people, went up the mountain early in the morning to cut bamboo and wood, made it according to the style of the drawing, and then carried it to the river, and fixed it in the water next to the river with a wooden stake. However, after the cylinder car was installed, it could not rotate, and Li Zhiyun estimated that the draft was not deep enough. He asked the group to submerge the cart deeper into the water, with the bottom of the wheels at least three feet in the water.

Everyone was busy again, and this time after loading, the water wheel only turned half a circle and then did not move. Huh, what's going on? Li Zhiyun stood there, staring at the tube car in a daze. Scarface couldn't help but say, "Lord Wang, can this thing be done?" Li Zhiyun didn't answer yet, and came to see the lively Yinggu and said: "The prince said that it can be done, then it will be done!" Scarface pursed his lips and shook his head, "I've seen enough." ”

"Brother Wang, do you dare to bet with me?"

"Bet on it."

"What if you lose?"

"I lost?" Scarface thought for a moment and said, "Then I'll lie on the ground and learn toads." Hey, girl, what if you lose? ”

"Isn't that easy? I'll make you a bowl of mushroom soup every day, too. ”

"Okay, let's make a decision!"

Everyone was laughing and laughing on the side, only Li Zhiyun stood by the river and meditated. If the cylinder car cannot rotate, it means that the kinetic energy is insufficient. Why is the kinetic energy insufficient? It may be that the water is not strong enough. There was nothing he could do about the speed of the river, so he could only figure out how to do it on the cart itself.

Suddenly, Li Zhiyun's eyes lit up, and he increased his forehead with his hand: That's right! Add more impellers! He hurriedly turned around and shouted, "Wang Baoqiang." Scarface hurriedly ran over and said, "Lord Wang, what's the matter?" ”

"You immediately have people make ten, no, fifteen planks, one foot five long, one foot wide, and half an inch thick, and put them on the water wheel when they are done."

"Okay!"

After the impeller was installed, the drum car rotated smoothly. The bamboo slip filled the water with water, turned to the highest place, and poured out all the water. Just install a wooden trough next to the drum to divert the water away.

When everyone saw that it had succeeded, they all cheered. Scarface patted his head and said, "Is it really done?" It's really evil! Yinggu smiled and said, "Brother Wang, hurry, lie on the ground and learn toads." ”

"Cheng, I'll study tomorrow."

"You don't have to cheat!"

Scarface shook his head at the cart and said, "This thing is godly." When the war is gone, I will disarm and return to the field, and I will do the same, and then I will not have to carry water to water the ground. Li Zhiyun said with a smile: "Wang Baoqiang, you are now a loyal general of the fourth grade, and you still use your own farming?" ”

Although the New Army is Li Zhiyun's private army, and the military salary is also paid by him out of his own pocket, the military status of the officers and men of the New Army is the regular establishment of the imperial court, and the official titles and ranks of the generals are also granted by the imperial court. Moreover, compared with the ordinary Tang Army, the rank of officers at all levels of the New Army is one or two levels higher, which is not only won by Li Zhiyun from Abba, but also by the officers and men of the New Army who fought bloodily and fought with outstanding achievements.

Scarface smiled, "Even if I don't farm anymore, I can teach the people in the village to save them a lot of effort!" ”

Li Zhiyun also asked people to go up the mountain to cut a large number of bamboos, split the bamboos in half, remove the bamboo joints in the middle, and connect them one by one to make a trough, bringing river water into the fertile fields.

In the evening, Li Zhiyun took Zhang Zheng, Cai Hu and Yinggu up a nearby hill. A sunset—so round, so big, like a bright red coral ball, shrouded the endless fields in a faint red light. In the distance of the river, five or six cylinder carts lined up, spinning day and night. Li Zhiyun pointed with his hand and said with a smile: "In autumn, the field is a piece of golden wheat. At that point, we won't have to worry about food anymore! ”

After Li Zhiyun led the new army to leave Guantang Town and go to Champion City, Zhu Cang ascended the throne and became emperor in Jutan City. Li Zhiyun is the king of Chu, and Zhu Cang has to suppress him, calling himself Emperor of Chu and changing his name to Changda, probably saying that under his leadership, prosperity will soon be reached.

On this day, Zhu Cang was drinking tea in the lobby, Wu Yuan walked in, hugged his fists and said, "Big brother, are you looking for me?" Zhu Cang pointed to a chair opposite and said, "Brother, sit down." Wu Yuan was not polite, and sat down on the chair with a grin.

Zhu Cang put down the teacup in his hand, looked at him and said: "Brother, after Li Tang's King of Chu fled, he led the army to defeat the Champion City, and our five thousand soldiers and horses were folded in his hands, and this revenge cannot be avenged!" Therefore, the eldest brother wants you to lead the troops to conquer the Tang Army and avenge the dead brother! ”

"Okay!" Wu Yuan nodded and said, "How many soldiers and horses are my eldest brother going to let me bring?" ”

Zhu Cang thought for a while and said, "There are 3,000 people in the Tang Army, and the eldest brother will give you 30,000, ten times as much as the Tang Army, how about it?" ”

"No problem!" Wu Yuan patted his chest and said, "Big brother, don't worry, the little brother will definitely kill them without leaving a piece of armor!" ”

The two were talking, and as soon as Zhu Cang looked up, he saw Yan Chuchu standing at the door of the lobby, probing his brain inside, so he raised his voice and said, "Mr. Yan, do you have something?" Yan Chuchu walked in, saluted respectfully, and then said: "Your Majesty, Yan just happened to hear the emperor outside the hall saying that he was going to send troops to attack the Champion City, Yan Mou has a few words in his throat, I don't know if to say it or not?" Zhu Cang didn't give up his seat, but said indifferently: "Mr. Yan has something to say, but it doesn't hurt to say it." ”

"Your Majesty, Yan heard that the King of Chu of the Tang Dynasty persuaded the farmers to recuperate with the people in the champion, which is a benevolent and righteous move. If the emperor sends troops to attack, he will surely trap the people in fire and water. The ancients had clouds, soldiers, and murder weapons. As soon as the provocation starts, the lives will be ruined! Wouldn't it be better for the two sides to call off their troops and make a truce and get along peacefully? ”

After listening to this, Zhu Cang said with a smile: "Although Mr. Yan is full of poetry and books, he is full of wealth, but he is not familiar with military affairs. In today's troubled times, all kinds of heroes are originally competing for each other and attacking each other. If I can't fight back, how can I gain a foothold in this troubled world? ”

"This ......," Yan Chuchu wanted to say something more.

Zhu Cang said coldly: "Mr. Yan doesn't need to say anything, go home!" Yan Chuchu had no choice but to give up his hand and say: "Yan is too talkative, say goodbye!" With that, he turned and walked out of the lobby.

Zhu Cang saw Yan Chuchu's figure disappear at the door, his eyes became as cold as ice, and said: "Like such a sour and rotten bookworm, eating me and drinking me, but helping outsiders talk, what use do you want him?" Wu Yuan took the opportunity to say: "Big brother, why don't you hand him and that Lu Congdian to the younger brother to deal with?" Zhu Cang nodded and said, "Okay, when you return victoriously, I will hand it over to you!" ”
