She knew what these villagers were thinking, and it was difficult to resist their enthusiasm, but Jian Yun still accepted the things they sent.

"Then thank you all very much!" Jian Yun knew that everyone's hospitality was difficult, so he accepted these things with a smile.

As she watched the villagers farm, she wondered if there was anything else that could be improved.

Just as he was thinking about it, he saw some villagers carrying buckets of water to the fields.

"This?" Jian Yun looked at these villagers with some surprise, but he didn't expect that their watering was actually picked up with buckets and buckets.

It's a lot of trouble, and the time and energy it takes is huge, and it's not cost-effective.

Jian Yun thought for a moment, turned his head to look at the village chief and asked, "Do we usually use this method for watering in our village?"

The village chief nodded, the location of Jianjia Village is not very good, the land is flat, but watering is extremely inconvenient, which is why the villagers are reluctant to reclaim the land too far.

Every time she went to the fields, all she saw was the land they had watered, and it was the first time she had noticed how the villagers were watering.

It's no wonder that when she said that she needed to water a small amount and many times, the villagers looked a little embarrassed.

"Hasn't there been any improvement in watering methods here for so many years?" Jian Yun asked as he looked at the village chief with some puzzlement.

The village chief shook his head, the villagers hadn't told him that they wanted to find a way to improve the way of watering, but he thought about it and thought of a lot of ways, but in the end it all ended in nothing.

"We also thought about storing a ditch here to water the fields, but it would be too costly, and the efficiency would not be much higher, so it would not be cost-effective. The village chief said with some distress.

What's more, if a ditch were to be stored here, it would be a problem for the villages downstream to drink water, and they would not be happy about it.

Seeing that Jian Yun was pondering, the village chief knew that she was thinking of a way, so he cautiously asked, "Do you have any ways to improve?"

When Jian Yun was asked about this, he nodded affirmatively: "Although this method is available, but it is a little troublesome, we can dig a canal here to divert the passing river water to the fields, so that there is no need to manually carry water." ”

They didn't think about this at the time, but if it was time for a flood, they couldn't control the water in the canal, and the whole land would be flooded.

So the proposal was rejected when it was proposed.

"Actually, this method is not very difficult, it is enough to set up a water blocking mouth at each checkpoint of the canal, and when it is the rainy season, then block these openings to prevent the water in the canal from flowing over. "This scheme is used a lot in modern times, diverting water into canals, irrigating fields, saving a lot of manpower, and can do many other things.

Theoretically, this idea is good, but in practice, no one has operated it, and the village chief is afraid that this plan will only stay in theory, and ......

"If we want to do this, we can, but this is a big project, which affects the water supply downstream, and we have to go through it if we are willing to do it in our own village. The village chief looked at Jian Yun with some embarrassment and said.

"I'm certain that I can do this, but if you don't agree, then we can only think of other methods, but no method is as good as this method, can you help me think of a way, village elder?" Jian Yun said after thinking about it seriously.

The surrounding villagers themselves had taken great pains to water and irrigate, and now after hearing Jian Yun say that there was a way, they all looked at the village chief eagerly, hoping that he could help think about it.

After feeling the gaze of the surrounding villagers, the village chief sighed: "Since everyone said so, then I will go to the town to discuss with the prefect and ask him to help coordinate and see if the construction can start as soon as possible." ”

If you want to report this matter to the prefect, you must have a complete design drawing, and Jian Yun quickly said that he can draw the entire design drawing.

When Zhang Shan received this project, he was a little surprised.

Having nothing to do, when Xue Gao, who was sitting on the side, saw Zhang Shan's expression, he raised his eyebrows and asked curiously: "Did you encounter something when you looked at the expression of the prefect? ”

When Zhang Shan heard Xue Gao say this, he hurriedly handed him the things reported by the village chief.

"Build a canal to help irrigation?" Xue Gao was secretly surprised in his heart when he saw the things reported by the village chief and a rough design map attached by Jian Yun at the back.

Especially when he saw Jian Yun describe in detail how to control the flow of water and ensure that it can be drained without drowning the crops, Xue Gao's heart was even more stunned.

You must know that irrigation covers most of the country, and many villagers have a headache for this area.

"There are many areas where villagers will have a headache because irrigation is too troublesome, this design plan seems very feasible, what do you think, Lord Prefect?" Xue Gao pointed to the design drawings and looked up at Zhang Shan and asked.

Zhang Shan also had a headache: "From a theoretical point of view, Jian Yun's design plan has greatly solved the problems we were puzzled about before, but this is not a small project after all, if it is to be done, it is necessary to mobilize a lot of manpower and material resources, so please also ask the prince to help discuss it with Your Majesty, we will first use Jianjia Village to do an experiment, and then make a final conclusion if it is possible." ”

Xue Gao nodded with satisfaction, when he came out this time, the imperial brother gave him great rights, but after thinking about it, he still decided to report this matter to the imperial court in writing.

He took the report letter back from Zhang Shan, intending to take a closer look.

"Lord Wang, if you want to say that this Jian Yun is really a strange woman, you said that this problem has plagued us for so many years, and even the officials of the imperial court have no good way to think about it, and she actually solved it?" Leng Yun looked down at the letter on Xue Gao's desk, and said in surprise.

Regarding the construction of canals to help irrigation, there have been court officials who have raised it before, but because it has not been able to solve it for a long time, the problem of how to control the flow of water has been stranded, and now in Jian Yun's report, the focus is on how to control the flow of water during the flood season.

Another method she uses is to build a canal on one side of the farmland to bring water from the water area into the farmland during the drier season. Xue Gao pointed to the left side of the blueprint and said.
