After riding for half an hour, gray suddenly covered his mouth and nose, rode quickly through this section of the road and came to the cabin not far in front.

The cabin was newly built and very simple, but it had no problem living. He also saw cooking utensils and tables made of several pieces of wood in the grass shed outside.

"He is a hard-working and factual person." Gray nodded, turned over and dismounted.

In front of the hut, several people were chopping the plants and trees in front of them, one by one.

"Your majesty!" Seeing who the visitor was, several people were so frightened that their kitchen knives fell to the ground and saluted quickly.

"Don't be polite. Let me ask you a question. Who made that thing outside?"

Gray recognized it at a glance when he saw it before. It was a composting method. He didn't think of anything. Instead, these people made it by themselves. It's really not simple. It can only be said that there are talents in any world.

Gray thought of the way, that is, the toilet, and then fermented ordinary manure. Moreover, this must be based on the large-scale use of the toilet. It has not been fermented in the toilet. Those things are not manure. If they are put in the field without fertilizer, it will be harmful.

So before the toilet is fully used, this composting method is very powerful.

"Your Majesty, it was adhema who did it. I dissuaded him from doing this smelly thing, but he kept dissuading." As soon as Gray's voice fell, someone came out and pointed to adhema and complained. It seems that dissatisfaction has been accumulated for a long time.

"It's... It's me." Adhema dared not deny that he did it. Some people had despised him before. He was afraid that the king was the same. He came to punish him.

Gray looked at the man who stood up and nodded slightly. "Later, you and I will meet Wang Du. I'll let the soldiers take you to the iron mine."

The man was overjoyed at the first half of the sentence, but his face turned green after hearing the second half, but he didn't dare to refute.

Then gray looked at adhema and said with a smile, "you can make the land more fertile and increase crop yield?"

"Yes, your majesty. I tried it in my own house. It's very useful." Adhema nodded, not as scared as before.

"You did a good job. This kind of thing is very useful. I will greatly appreciate it if you write down this method." Gray said, taking paper and pen out of his backpack.

"I... I don't know words." Adelma said cautiously.

"Well, come on, I'll write it." Gray pulled a small stool they were sitting on, sat on the ground, spread out the paper and waited for him to read.

"Your Majesty, I can read. Let me write it?" One man said carefully.

Adhema was one of the twenty agricultural masters he found to grow the crops he brought back, each with five assistants. Considering that they may not be literate, some of them explained the planting methods for them.

"Good." Gray nodded, got up from the ground, patted the dust on his ass and let another person record.

After recording this, gray immediately took out 20 gold coins from his backpack and handed them to adhema, "this is your reward. If you find any way to increase crop yield in the future, you can tell me and I will give you more rewards."

Adhema excitedly reached for the gold coin, knelt down and knocked his head, "thank you, your majesty."

"I call this method adhema composting method, and then give it to farmers all over the country. Do you think it's ok?"

"Yes, it's my pleasure. Thank your majesty for his trust." Adhema said excitedly.

"Your name will be remembered by history." Gray smiled and patted him on the shoulder. He left here and returned to the palace. He immediately asked people to copy hundreds of copies and send them to all places in the name of the king.

As for the guy who doesn't even know his name, naturally someone will give him a job to create wealth with both hands.

"Why did you run?" The elf flew by and looked at him angrily.

Gray laughed a few times. "I've done another good thing for the country and the people. Isn't it great?"

"Your Majesty, what did you send this time? Why don't you discuss it with me? " Soon after the things were sent out, the archon of the Kingdom hurried over for fear that gray would make any wrong decision.

"Father, you may not have heard of this. I call it composting. The fertilizer it produces can make the land more fertile and produce more food." Gray explained excitedly.

The sweet potato and other things he brought before can't be planted on a large scale in a short time. If you want to plant on a large scale, you must wait for these crops to be harvested, and then don't use them at all. They can be used as seeds before they can be popularized on a large scale.

Therefore, if we want to really see the large-scale cultivation of sweet potato crops all over the country, it will not be possible until next year.

But this thing is different. As long as you want to do it, you can certainly find raw materials to make fertilizer, because the raw materials of composting are just crop straw, some weeds, trees, branches and leaves, etc. can be used as raw materials, which can be seen everywhere in the kingdom.

With this, farmers start composting this year and can use it next year. As long as there is no natural disaster next year, grain output will definitely be more than this year.

Moreover, with this, the output of sweet potato can also be increased. At that time, there will be no need to worry about food at all.

Listening to Gray's explanation, the Marquis doubted, "is it really so good?"

"If my father doesn't believe it, he can send someone to adhema's house to investigate. I'm sure his family's grain output must be more than that of other families." Gray said with great certainty.

He believes that even if others don't believe Adelman and don't want to make efforts to do this, Adelman himself, as an inventor, will certainly be used on his own land, and he himself said before.

"If it's true, then... Lord Marquis sketched. If it's true, it's really influential.

"Father, just go and check. This kind of thing can't be fake. If it's true, it still needs his father's help." Gray said seriously.

If gray dealt with it himself, he must have enforced it in the name of the king, not because there was no other way, just because it was the simplest and most effective way.

However, this may cause complaints from some people.

But it was clearly for their good. Gray didn't want to complain and was scolded as a tyrant by the people. Even if they would thank him later.

If the Marquis was allowed to deal with it, his means would be more gentle, and there were more other ways to make them believe that it was indeed true.

Therefore, in the follow-up of this matter, I still have to bother Lord marquis to deal with it. I believe he will spare no effort to promote it and adopt appropriate methods after he knows the effect of composting.

"If it is true, I will try my best to promote it, and you should put some thought on it." The Marquis said seriously, "if this is really useful, you can unite your people in the Kingdom, let the people of the whole country support you, and completely forget what happened before."

Although gray is now a dragon slayer and king, and there is no sign of instability in the Kingdom, the last lesson is enough to show that his foundation is not stable, and many people still want the old king.

Even now the old king's family are dead, but these people dare not resist, but they may not really be convinced.

What's more, there was no trouble because of the majesty and strong military strength of the Dragon slaughtering warriors, but the majesty of the Dragon slaughtering warriors was only majesty, not the support of the people.

But once this composting method is really useful, the Sutton family will become a real royal family. No one will remember who the former king was. They will only remember that the Sutton family gave them a better life.

"Father let go and I will fully support you." Gray nodded and took the elf back to the treasure room. His magic recovered a lot.
