The body of the overturned car uses wooden boards to make a long groove, which is two meters long and not a certain length if it is wide. Some are four inches, some are seven inches, and they are about one foot high.

There is a walkway board in this long groove, and the width of this walkway board is approximately equal to the width of the long groove, but its length is one foot shorter than the two ends of the long groove. Where it is shorter than the long groove, it is used to place two wheel axles with larger and smaller wheel axles.

In addition, there are keel plates on the upper and lower sides of the pavement plate. The large axis is placed on the shore, and the two sides of the large axis are connected to the carbides with four small wooden sticks. As long as people rely on the rack and step on the small wooden stick, they will steer the carbide. When stepping on the carbide, it will drive the keel plate. At this time, the keel plate will rotate around the pavement plate to wipe water and go to the shore.

If the fields are not on the shore, but on high grounds with higher water, three overturns can be used to irrigate. The three overturns are connected by small pools, so they are connected to take water to the shore. In this way, you can irrigate fields on high shores that are more than three meters long.

The overturning car in front of everyone was set up with a water turnover, which used the power of the river to scoop the water into the water bucket, rotated it down, and led it into the canal.

Liu Fan asked him to dig a deep and narrow ditch on the bank of the river first and place the water truck in it.

Extend the pedal shaft of the overturn and make a vertical wheel. Next to the vertical wheel, set up a wooden shaft, and make two upper and lower lying wheels on the shaft. The upper lying wheel and the vertical wheel are the head wheels, and the two struts intersect and intersect and intersect. The water is used to stimulate the lower lying wheel.

The water rushes the lower lying wheel. When the lower wheel moves, it drives the upper lying wheel, and then drives the vertical wheel that is intersected with the upper lying wheel. Using the principle of gear connection and the principle of gear connection, it drives overturning in the ditch on the side, and the water is transported to the shore.

Or the lower lying wheel can be converted into a separate vertical wheel at the front of the car, so that its web support is also intersected with the upper lying wheel, and then stimulate water to push it, and the effect is the same. You can also convert the lower lying wheel to a push rod and push it from the livestock.

"The water comes out, it comes out..." everyone exclaimed.

The people nearby also stared at each other and cheered.

With this thing, do you still need to run miles to carry water with a bucket?

When the craftsman completes the operation, he scoops of water from the river and scatters it on the ground.

If a canal is drawn at this time, the canal can lead water into the fields in the distance.

But this is no longer important, and everyone can think of this.

"Okay!" Liu Fan smiled with relief. With the keel waterwheel, the people no longer have to worry about ordinary droughts, and there will be a good harvest every year.

This is a water-turned keel waterwheel, which does not require manpower.

The biggest advantage of water turning and turning is that it saves effort. Because it uses the power of nature, human and animal power can be used for other production activities. In addition, this method of water transfer and irrigation can be used day and night.

However, this method also has some disadvantages. Once the water level is too strong, it is easy to cause the keel plate to break and cannot be used.

But there is no way, this is the limit that craftsmen in this era can achieve. When the time is ripe, Liu Fan will use a barrel car instead of a water turnover.

"The General of the Cavalry is really a brilliant trick in the world." Cai Yong said with tears in his eyes.

For Cai Yong, Mingguang armor and armor gear are far less effective than curved plows and keel water wheels.

The curved plow and the dragon bone water wheel are all actions that benefit the country and the people, and benefit the people of the world.

"It's nothing, I'm just imitating my predecessors." Liu Fan waved his hand and said, "The curved plow and the dragon bone water wheel are effective. I ordered the craftsmen under Shentugang to make some curved plows and dragon bone water wheels and distribute them to the people of various counties. This technique is also announced throughout the world. There are many droughts in the Central Plains. With water wheels, it can help countless people."

Only Ma Jun is the one who can be called "the world's ingenuity". He is a craftsman and a genius in machinery.

"The General of the Cavalry is unparalleled! Everyone in the world will respect the General!"

Everyone praised Liu Fan like this.

These things are not military supplies such as weapons and armor, so there is no need to hide them.

Liu Fan wouldn't be so mean to use this skill to make money.

Everyone in the world is about to die!

"Report..." At this moment, a cavalry came from afar and when he arrived in front of Liu Fan, he dismounted and said, "Report to the General of the Cavalry that the Xianbei Shanyu and the Company sent envoys to Yinguan City."

"Prepare to go home!"

This must be the one sent by Lian to form an alliance with him.

Although they have to play with He Lian in between applause, some of the things on the surface still have to be done.

After the people's worship of the Prime Minister, Liu Fan left by the water.

After Liu Fan left, the people gathered next to the keel waterwheel and were full of admiration.

...

"I am Moju, the right commander of the Xianbei Daduwei, and the confidant of the Da Shanyu. I dare to ask the General of the Cavalry, I am sending you to the Han Kingdom. Is this the way for you to treat guests?" Moju pointed at the Han cavalry behind him and said to Liu Fan in Chinese. His face looked very bad.

As soon as Liu Fan returned to Yinguan City, he came to greet the messenger of Shanyu.

But this Xianbei commander named Moju was very arrogant and sat on the war horse and was arrogant.

Not far behind Moju, there were five hundred Han cavalrymen, who were sent by Guan Yu.

Guan Yu was afraid that Moju would do evil after he came to Yanmen, so he sent five hundred cavalrymen to stare at them.

"Where!" Liu Fan ordered the 500 cavalry under Guan Yu's command to return to Qiangyin, and then evaded Moju: "The envoys don't know that there are many robbers in Yanmen. I am afraid that the envoys and others will encounter danger, so I will send cavalry to protect them. If the envoys make any mistakes, how can I explain to the Shanyu?"

After hearing this, Moju thought that Liu Fan showed weakness to him, his face calmed down a lot, and said, "The Great Shanyu asked me to bring the best minks, sheepskins, etc. to the general to express my feelings."

The Moju group has less than a hundred riders and no cars, so they definitely can't carry much fur. This is just like the rumors, and it's really stingy.

"I thank the Great Chanyu here! Please invite the envoy to enter the city with me. I have prepared wine and food for reception." Liu Fan asked Moju.

"Yes!" Moju raised his head with satisfaction, facing the sky with nostrils, and looked down on everything.

The Great Shanyu had tens of thousands of elite cavalry under his command. If the Great Shanyu had not blocked the Xianbei tribes, Yanmen would definitely be trampled by the cavalry of the Xianbei tribes.

Moju believes that Liu Fan deserves to treat him like this.

"I wish I could stab him to death with one shot." Zhao Ji red eyes and held the spear tightly.

Mo Ju raised his own value and had no idea that he was in various places. He dared to be so unreasonable to the general.

"Moju's arrogance does not exceed the bottom line in my heart. He is now proud and will cry to the corner soon." Liu Fan smiled and comforted Zhao Ji with a pleasant face.

In the face of big events, Liu Fan has no need to argue with such people or such small things.

Mo Ju thought he was self-righteous and regarded Liu Fan's courtesy to him as Liu Fan's awe of them.

Yes, when they became the target of public criticism, they gave them a large number of gold, silver and jewelry in Xianbei.

Moju naturally thought that Liu Fan wanted to seek their protection.
