On July 12, the recent replanting was finally over, and this time it was almost Wen Xiangheng who organized nearly 300 young and strong households in the entire mining estate, as well as women and children who could be mobilized, to grab seeds, in order to get a good harvest in the first year of Lin Yuyan's fiefdom, in order to alleviate the financial crisis in His Royal Highness's mansion.

The Zongfu sent Wen Xiangheng to Lin Yuyan as a staff member, and the most important role was this.

However, in the next period of time, Wen Xiangheng did not want to be idle, because in order to regulate the water consumption of the farmland in Huyi, Wen Xiangheng would organize the excavation of a water canal more than ten miles long for drainage and irrigation water.

However, what Wen Xiangheng didn't expect was that after His Royal Highness heard the news of digging a canal and saw the route set, he put forward a different opinion: "Wen Qing, why did you dig the ditch to a length of more than ten miles, instead of directly leading the ditch directly into this yellow land?" ”

The yellow land is not far from the water and is low-lying.

Wen Xiangheng looked at Huangdi and replied: "Huangdi is already low-lying, His Highness introduced the ditch into Huangdi, wouldn't it make the original people living in Huangdi flooded?" ”

Lin Yuyan shook his head and said: "Wen Qing misunderstood what I meant, you see, there are just a dozen large and small households before and after Huangdi, try to move away, Huangdi is low-lying, it is precisely because of this, plugging the gap here, isn't it forming a natural water storage lake?" ”

"Besides......" Lin Yuyan paused and said: "The channel that Wen Qing originally chose is really too long, a full ten miles, and the water will be secreted into the small berth of the land, which will be twice the result with half the effort, and do not choose the yellow land, so that the saved construction period will be directly used to expand the waterway and increase the water storage area of the yellow land, in this way, wouldn't it be twice the result with half the effort?" ”

Wen Xiangheng thought carefully about what Lin Yuyan said, but it was only a few breaths of effort, and he was sure that this suggestion was feasible.

After all, the dozen or so families in Huangdi are often threatened when the water is overflowing, and even if the canal is opened, because the terrain of Huangdi is already low-lying, it is difficult to actually solve the problem of Huangdi.

Unless it is manpower, the terrain of the yellow land is filled with soil.

However, this is much more wasteful than His Highness's proposal to "relocate the Yellow Land residents".

In addition, there are hidden dangers in other aspects.

"Your Highness, this plan is feasible!" After Wen Xiangheng thought about it, he also affirmed.

After all, the relocation of a dozen houses is really nothing for a 300-household mining estate, and it can also greatly shorten the time for digging ditches, and the water storage in the yellow land can also solve the disaster of flooding in the mining area.

What a strategy to kill many birds with one stone!

"It's useful," Lin Yuyan also nodded and said.

Wen Xiangheng saw Lin Yuyan's not salty and indifferent look, and he also thought that His Royal Highness was not interested in it, and he didn't understand the manpower saved by this plan, so he explained: "This idea put forward by His Highness is really useful for the progress of the construction of the mining estate!" ”

Lin Yuyan naturally understands the role, but what he is thinking about now is that the current mining cannot meet the development state in Lin Yuyan's mind, for example, some agricultural tool designs that have been active in Lin Yuyan's mind in the past few days have not been actually built, and Lin Yuyan is also helpless.

One of the most troublesome things is that Wu Guo's control of iron tools is really strict, and iron casting can only be controlled by the military, and the production of standard weapons is also a standard.

When Lin Yuyan wanted to explain to Wen Xiangheng that he wanted to borrow iron tools to make farm tools, the latter also looked at him with a strange expression and said: "Your Highness's idea is really too ridiculous, iron tools are the enemy's killing weapons for the soldiers who defend the country, and they are used for agricultural work, which is a bit too wasteful!" ”

In contrast, Lin Yuyan also accepted the opinion and nodded, after all, after a little thought, you can know how important weapons made of iron are to the soldiers of the martial arts who fight all year round.

To tell the truth, the border of Wuguo is the southern part of Qinling, Nanyang, which is a rich area for the distribution of iron ore, but due to the national strength of Wuguo, the iron yield of iron ore is low and pitiful, and it can only use good steel on the blade, and use these iron ores in casting weapons.

Lin Yuyan could only settle for the next best thing, choosing bronze as a casting agricultural tool.

However, Wuguo's control of bronzes is not very relaxed, and the closest to Caiyi is that there are only a few copper casting shops in Miyang City, which are still subject to the government of Miyang City.

Although Wen Xiangheng thinks that it is too wasteful to cast agricultural tools with bronze, his Royal Highness looks like he has made up his mind, which makes people unable to persuade him at all.

Wen Xiangheng was also helpless, so he asked people to go to the official mansion of Miyang, issued a document in the name of Gongzi Yan, and called several bronze craftsmen.

In the past few days, Lin Yuyan has often come to Li He, painted various pictures on the sand, and explained to Li He over and over again the purpose and construction of this object.

Li He is worthy of being a master craftsman who has studied carpenter's work for decades, and Lin Yuyan fully understood it with a little explanation, and even put forward a few feasible suggestions.

"Your Highness said that this is a 'ploughing rake', which is used as a crushing flat land? This 'curved plow' was used as a plough? And the 'keel waterwheel' is used to carry water? Li He also questioned.

After all, the main body of the farm tools designed by Lin Yuyan is still made of wood, and Li He is still quite proficient in this.

In this regard, Lin Yuyan nodded.

Of course, after this set, Lin Yuyan has other object compositions in his mind, but he still focuses on these three pieces, and the others are still difficult to use on a large scale.

Li He couldn't help but say: "Your Highness is really whimsical, but what Your Highness said is so good, you still have to wait until it is built and try it to know if it has such a big effect." ”

Hearing this, Lin Yuyan nodded and said, "After finishing a sample as soon as possible, I asked Mr. Wen to find a few bronze craftsmen from Miyang City to help you build the key parts and see how the effect is." ”

Li He's eyes lit up when he heard the bronze craftsman, he really didn't expect that His Royal Highness from Wancheng would be so attentive to these agricultural tools that didn't know the specific function. Do not hesitate to mobilize bronze craftsmen to create bronze parts for agricultural tools?

That's a lot of money!

Looking at these compositional paintings on the sand, Li He's eyes also warmed up, seeing that His Royal Highness was so attentive to these pictures, Li He didn't dare to slack off.

At the moment, he also responded: "Your Highness, although rest assured, Li He will definitely go all out to create a few samples and come out, and he will not disappoint His Highness!" ”
