On July 15, Li He's family moved the models of the three farm tools created by the "ploughing rake", "quyuan plow" and "keel waterwheel" to the house where Lin Yuyan temporarily lived.

Of course, Wen Xiangheng also bought a few ploughing oxen from Miyang City, which was also to test whether the ploughing rake and Quyuan plough were as magical as His Royal Highness Gongzi Yan said.

The bronze bone blade of the ploughing rake and the plough blade of the curved plough were all installed in the design position of the ploughing rake and the curved plough by the bronze craftsmen invited by Miyang, and the size was just right.

Li He was also present in person, and in the process of building these sets of farm tools, he gradually discovered that the structure of these sets of farm tools was really a little ...... Fantastic......

It's hard to imagine that something so ingeniously conceived could be used for farming. And it's still in the hands of a royal son!

Li He came to the scene to see if this thing could greatly save manpower as His Royal Highness Gongzi said.

The site of this experiment is in the south of the caiyi, the waterfront, because of the excavation of the Yellow Ditch, the key direction of the future reclamation and cultivation of the entire mining will also be the north bank of the water, but also because of the perennial summer flood problem of the water, the farmland cultivated here is really a minority, Wen Xiangheng is also ready to plan to reclaim this fertile land, and build a large number of new fertile land.

After all, the excavation of the Yellow Ditch has at least made the north bank of the water a fertile land, which is really suitable for farming.

Li He saw that on the land on the north bank, there were several cows grazing with their heads down, cows, although this is common in Wuguo, but it is basically used as a vehicle power, used to transport things, Li He also understands that His Royal Highness Gongzi Yan directly planned to use cattle as a source of power at the beginning of the design of these things.

[Cow is a precious thing......]

Li He thought in his heart, most of the cattle in Wuguo were used for military transportation, or simply to serve the wealthy families and use them for agricultural production, which Li He seemed to have said from someone from Zheng Guo in the east, but it was by no means the norm.

Because the Yellow Ditch is being excavated, the custom that was originally set to be "about three zhang wide and three zhang deep" has been changed to "about five zhang wide and four long deep" because of the shortening of the construction period and the reduction of the amount of work.

The residents who originally lived in Huangdi were relocated to other villages, and an earthen dam was being built around the entire Huangdi Canal.

Wen Xiangheng returned, looked at Lin Yuyan and saluted, and looked at the figure under his eyes to come to a similar situation, before signaling to Lin Yuyan that he could start.

For these farm tools, Lin Yuyan only has a general impression, the specific operation is honest, I am afraid that Li He, who has not yet built these farm tools, is familiar with it, so at the moment Lin Yuyan said: "Please also ask Li Jiang to put farm tools on these cows." ”

When Li He heard this, he walked to the side of several cows, led them to the side of the farm tools, and began to put some of the tools belonging to the cow's body on the cow's body.

At the same time, the keel waterwheel, which was several feet long, began to put its tail into the water, ready to lift the water.

Li He personally picked up the Quyuan plow, put the position of the plow shovel into the soil, and looked at Lin Yuyan and asked if he wanted to start.

Lin Yuyan nodded and said, "Let's start, it's the first time for Craftsman Li to use these things, and he is not yet proficient, so he still has to be careful......"

Li He nodded, but in order to make sure that in case, the work of morning glory was still assigned to the original owner of these cows, who was also a chauffeur.

"It's okay to pull!" Li He said, and the coachman who was leading the cow in front of him hit the cow's buttocks with a whip, and he quickly ran to the front of the cow and took the reins.

The hooves of the cow move slowly......

Li He's heart beat faster, and he stared at the plough shovel without moving, and sure enough, he saw that with the straightening of the hemp rope, the plough shovel began to move slowly, because the downward design was directly in the soil.

The ox walks very slowly, but steadily.

In a few breaths, the ox took a few steps, and the zigzag plough moved more than a kilometer......

"This ......"

Li He's eyes widened when he saw the land passed by the plough of the curved plow, and the soil that was originally buried a foot deep in the ground was turned over, and the slightly moist soil seemed to have earthworms even drilled out of it.

However, in just a few breaths, it is possible to turn over the soil more than one zhang, and Li He is also very surprised, after all, if such land is dug up by manpower, at least more than 100 times will have to be waved to be able to reclaim such a small piece of land.

This thing actually works!

Wen Xiangheng naturally also paid attention to this movement, seeing the appearance in front of him, he also looked at his Royal Highness, when he wanted to praise his Royal Highness, but found that the latter frowned, as if he was not satisfied with the performance of this Qu Yuan plow, Wen Xiangheng had to ask: "Your Highness, it seems that you are not satisfied with the performance of this Qu Yuan Plow?" ”

Lin Yuyan nodded and said, "It should be that this land is too dry, so the cattle ploughing is so slow, Mr. Wen can let the keel waterwheel first lift water from the water to make this piece of land wet......"

Wen Xiangheng naturally agreed, so he found a few strong men to walk to the keel waterwheel and began to lift water.

Everyone was about ten feet away from the place where the waterwheel was, and their focus was on this Quyuan plow, so they did not go to the keel waterwheel.

Because of the performance of the Quyuan plow, Wen Xiangheng is also extremely optimistic about this keel waterwheel, and is more concerned, if this thing is really as his son said, then, the Yellow Canal will play its greatest function.

After all, the Yellow Ditch is already set to be four zhang deep, which undoubtedly greatly reduces the threat of flooding in Gongziyan Caiyi, but in the same way, if the water surface is too deep, it is not beneficial to the cultivation of farmland, after all, lifting water from the bottom up is a thankless task.

Of course, this was not at the time of this keel waterwheel.

Wen Xiangheng said in a tone full of anticipation: "You guys start......

A few strong men squatting at the position of the dragon head of the keel waterwheel held a few horizontal plates at the dragon's head and began to rotate.

Wen Xiangheng looked down and saw that the keel leaf row on that side was rolled upward, and there was still a splash of river water on it.

"Can you really ......" Before he saw the water come up, Wen Xiangheng was determined, and sure enough, when his muttering fell, he could see a steady stream of water being lifted from the river to the shore, and then slowly flowing along the land on the shore to the surrounding area......

Wen Xiangheng was full of excitement, but he didn't know if this excitement was directly because of this keel waterwheel.

He looked at Lin Yuyan not far away, and also signaled the meaning of bringing up the water, but the latter was interested, looked at Wen Xiangheng and said, "Mr. Wen, let's sort out a small communication water ...... first."
