As the saying goes, if Lin Xianyu, the county lord, repeatedly rescues them, it will only make those people feel that Lin Xianyu should help them.

However, if the road is built, it will not occupy agricultural time, and it will allow the farmers to eat a full meal, which will kill two birds with one stone.

Of course, this will have to wait until winter, but Lin Xianyu plans to plan it by himself first, and then discuss it with his brother and them, and take a look at the map of the three counties by the way.

The most important thing now is to find the right location for the water truck.

Lin Xianyu found that although there are also waterwheels in the south of the Yangtze River, most of them are extremely restrictive, especially in places where the terrain is not so gentle.

The waterwheel made by Lin Xianyu to longevity is a high-barrel waterwheel that was only invented in the Ming and Qing dynasties in ancient China, and the effect is naturally different.

Lin Xianyu walked leisurely on the road, but no one thought it was strange.

After all, the style of study tours in Jiangnan is very prosperous

As the saying goes, it is better to read 10,000 books than to travel 10,000 miles, and students in Jiangnan, regardless of whether they are rich or poor, will find a way to see the customs and customs of various places to broaden their horizons.

And although this brother looks old, he is full of bookishness, and at first glance he is a student from a middle-aged family who comes out to study.

In the aftermath of the drought, more and more people came out to study.

Because according to the law of the past years, the township examination two years later has been followed by the subsequent examination, and the questions in it must be about this disaster.

It's not surprising that students come out early to get material.

Lin Xianyu was also very satisfied when he saw that the farmers were busy sowing seeds, at least his thoughts were not in vain.

Lin Xianyu suddenly discovered a strange thing, there were actually two oxen plowing the field in this field, and they used a long straight wheel, not a short curved wheel.

Originally, she thought it was an accident, but after walking a lot of places, she found that they were all long straight wheels, not improved curved plows.

Quyuan plow, this is a big killer in the late Tang Dynasty.

The long straight wheel was changed to a short curved wheel, which brought about a step-like increase in productivity.

Compared with the straight plow, the curved plough has shortened the plow frame, added a plow evaluation and a plow wall, so that two oxen used to be pulled into one cow, and realized deep ploughing, which can make it easier for the people to reclaim wasteland and increase the area that individuals can cultivate.

This should have appeared at the end of the Tang Dynasty, but it didn't appear, Lin Xianyu always thought that the time and space he was in was just after the Tang Dynasty, and magically turned a corner, because most of the previous history looked similar.

Even the great poets Li Bai, Du Pu, etc., who appeared in the Tang Dynasty, also appeared on time......

But now Lin Xianyu realized that this time and space might not be what he imagined, but Lin Xianyu frowned.

In fact, it is not difficult to invent this curved plow, and you can do it casually, but now I don't know if it's too late.

Lin Xianyu thought about it, but he went back to the county government of Lishui County this time, planning to tell Xie Yun the principle of this Quyuan plow, and let Xie Yun start to study it.

After Lin Xianyu arrived at the county office, he reported Lin Xian's name, and Xie Yun took the time to meet her.

"Brother Lin, aren't you going on a study tour?" Xie Yun was a little curious as to why Lin Xianyu came to her.

"I want to ask Master Xie, is this plough used to plough the land?" Lin Xianyu was afraid that he had made a mistake, so he deliberately asked Xie Yun.
