Before going to the pioneer publicity, Hannes took care of his image a little, took a cold shower in Ian's room, and shaved his beard.

After putting on his uniform, it looked like he was finally a bit of a soldier.

The four of them followed Hannes and went from house to house, so that everyone would meet by the river tomorrow morning and have something important to announce.

The workers who had been making the watermill together saw Hannes and knew that it was time to announce the waterwheel, and shook hands with Hannes with great pleasure.

The next morning, most of the inhabitants came to the river and saw the wooden wheel turning.

"This newly developed farm tool is called a waterwheel!" Hannes stood on a wooden bench and exclaimed, "With this thing, you can irrigate the fields day and night!" ”

"It's hard to open up farmland in a new place, but I hope you can regain your confidence! This year's crop is sure to be abundant! ”

There was a commotion below, and the residents began to discuss.

"It's the first time I've seen a farm tool like this... Looks like it's powered by water? ”

"Great! In this way, the seeds in the field will sprout quickly! ”

"It seems that you can also come here to get water in the future, it's really a good thing..."

Hannes cleared his throat and clapped his hands vigorously, "That's it! All right! Everyone, be quiet! ”

Several workers brought tables and chairs, and Ian sat on chairs with paper and pens in hand.

Hannes explained to the residents: "This waterwheel is public, although it does not look very large, but it can irrigate a considerable area of farmland, and those who want to cultivate fields in this vicinity should come to me and register it, and after counting the number, they will give you the right to use the land in this vicinity equally, and everyone's fields can be irrigated by waterwheels!" ”

Hearing Hannes's words, everyone rushed forward.

"I want a field!"

"I want it too! I want it too! ”

"Line up, line up!" Hannes beckoned the workers and soldiers to work together to maintain order.

At Ian's suggestion, he enlisted a few of his soldier friends to help, and barely managed to make the residents line up in a long line.

The registration lasted for one morning, and many names were recorded on the list.

Due to the preferential policies for refugees, there is no tax on the grain produced in the first year, and the peasants can get as much grain as they produce in the fields, so everyone who can afford to farm is very active.

In the afternoon, under the classification of Ian and others, they divided the land along the river equally among the residents, and each of them was given almost one and a half acres of land.

The next day they visited the house again, called the registered residents together, took them to the river, and designated the location of the land piece by piece, and resolved any opinions and contradictions on the spot, so as not to have any major problems in the future.

It took two days to divide the land smoothly.

Oxen were brought in to clear new farmland, rivers flowed down canals into the fields, and the refugees' enthusiasm was ignited with waterwheels.

They dug up seeds from areas far from the river and transplanted them into new fields.

New fields are slowly taking shape, but Ian wants to do more than just make this open field prosperous.

There were only 500 people living in the place, and in a month there were at least thousands, if not tens of thousands, of refugees pouring into the Wall of Rosai from the Wall of Mary, and he had to extend the watermill to all the frontiers in order to feed them in the autumn.

This was not so difficult, because the government and the aristocracy did not have much energy to manage the sudden influx of inhabitants, and their management of the frontiers was essentially left to their own devices.

If the refugees make trouble because of food, they will be sent to the giants to eat, which is what the government did in the original book.

Except for sending a few soldiers to watch, the Frontier was almost completely autonomous, and the promotion of the watermill would not be under pressure from the administrators.

Ian took the opportunity to ask Hannes to help promote the waterwheel.

Ian gathered the people who had been working together to build the waterwheel and formed a team to build the waterwheel.

It's already May, and time is tight.

After Ian explained the stakes to Hannes, Hannes enlisted the help of some of his soldier friends, most of whom were garrison soldiers who had escaped from Maria's Wall.

These soldiers have their own personal connections.

The soldiers within the walls are trained and the semester system is implemented, and the soldiers in each period basically know each other, and the top ten can go to the interior and join the Central Military Police Corps, and the rest voluntarily join the Survey Corps or the Garrison Corps.

After the soldiers left the military academy, they were assigned to different villages and strongholds, but they did not forget the time they spent training together, so at least one or two soldiers from each frontier knew each other.

This makes things very simple, and with Hannes' introduction, Ian leads the construction team to various pioneering sites to promote waterwheels.

He showed the drawings to the local carpenters, and taught the carpenters there how to build waterwheels, and when he taught, he mentioned Hannes's name and said that it was a farming tool made by Mr. Hannes so that everyone could eat.

Then one pass two, two pass four, four pass eight... The drawings of the watermill were like dandelion seeds flying in the wind, spreading throughout all the frontiers.

In just half a month, this thing has been publicized in all the pioneering places, and the name Hannes has also had a place among the refugees.

When the refugees talk about the watermills, they thank Mr. Hannes.

Even the soldiers of the frontier had a different opinion of him, and his fame quickly rose, which was exactly what Ian wanted to see.

On this day in mid-May, the sun was shining.

Ian stood beside the waterwheel, listening to the sound of the water flowing down the dug channel into the fields, and all the crops sprouted and flourished.

In addition to the waterwheel, he also borrowed the name of Hannes to promote the use of human fertilizer, and the refugees who rebuilt the village did not care about the tradition of unclean human fertilizer, and tried to increase the grain harvest as much as possible for this year's grain harvest.

"Alan, Mikasa, look!" Armin pointed to the paddy field in front of him: "I can't believe that we have facilitated all this!" We did it! Live in the Pioneer Land! ”

"No... It's not something we did—" Alan shook his head, staring at Ian's back.

All three looked at the back, watching his long hair move in the wind, and there was no wave in his blue eyes.

Armin immediately realized that it was Ian who was driving all this throughout, and he suddenly felt that Ian would do something great one day, maybe... will change the world...
