"Caw! It's Lady Yinla!"

"Lord Yinla, we love you dearly!"

“waggggh!”

Yinla nodded in response to the goblins' welcome, while observing their living conditions... It seemed quite convenient for them to move around, and they appeared to be living comfortably.

That's good...

"Mr. Yinla, will all the houses be built according to this standard?"

In response to Xiao Gang's question, Yinla nodded and looked at him and the constructs behind him, saying, "It seems the goblins are quite satisfied, so let's get started quickly."

Given the efficiency of the constructs, the repairs should be completed in a few days. Then, the cement roads will be completely covered in the Demon Lord's territory. If the houses and roads are built together... the production of limestone will probably be quite tight.

We'll need to figure out a solution then...

Thinking this, Ira ignored the goblins mating in one of the dozen or so houses. He gestured to the little goblin following him and said, "Take some goblins with you, and I'll teach you what 'rotation breeding' is."

In this world, the land of the principality actually implements crop rotation... After all, this world is not entirely inhabited by primitive people, and Yinla is not so arrogant as to be that kind of person.

Every living being tries to find a way out for the future.

This is also a kind of luck, otherwise, Yinla, who eats synthetic food every day, wouldn't have a very specific understanding of the ancient era's cycle of life... Basically, she could just follow the principality's approach.

"The so-called crop rotation is to plant different crops in the same field in a regular order to replenish soil nutrients, which can save on fertilizers that are currently very scarce."

As Yinla spoke, he looked at the little fairies and goblins who were listening attentively... In fact, even the goblins listened to him more attentively than the leaders.

"Moreover, it can also squeeze out the space for weeds to grow. Although the expected cultivated area has increased many times over, your workload will not increase... but the yield will genuinely increase."

As Yinla spoke, ignoring the admiring glances from the goblins and the summoned lesser demons, he got straight to the point: "The duchy's lands are managed through a system of multiple cultivated lands and rotational fallow."

"The land was divided into three plots. While wheat was planted on the first plot, the other two plots were used to plant radishes, alfalfa, chrysanthemums, and beans in rotation during the winter, spring, and summer seasons, thus filling all three seasons."

"Radishes are planted in winter and harvested in spring; alfalfa is planted in spring, harvested one crop after another, and then replanted in summer; beans are planted in summer and harvested in autumn... With the addition of fertilizer, the land will not suffer much damage."

As Yinla spoke, he explained in detail how the land was rotated, saying, "The first plot of land planted with wheat in the fall is then directly transitioned to bean cultivation after the summer harvest."

"The work of planting wheat continues to the next plot of land, and the planting is carried out in a three-year cycle."

As she spoke, Yinla pointed to the large field in front of her planted with blue ginseng, looking at the mushroom bags, and said, "Of course, we certainly won't choose to continue using the existing land... We can just set aside a separate area and imitate the way the duchy is planting it."

Although people in the Demon King's territory often eat bread, the staple food here is still Blue Qin Gu, since the yield of wheat is really incomparable to that of Blue Qin Gu... Bread is more like an occasional treat, something delicious, rather than a proper staple food.

If Yinla were to gain experience from the knowledge she has learned, the crop rotation scheme related to fungi would be fungal-rice rotation, but the main crop of that method is rice rather than fungi.

The harvest of Scutellaria baicalensis is very fast and has a high carbohydrate content, which is certainly a good thing. However, if this continues, the soil will really be overloaded... There are ways to let the soil rest.

“From our current isolated field, expand to the left and right at equal distances. Plant and harvest a batch of Scutellaria baicalensis in the first field, and then plant it in the next field.”

As Yinla said this, he looked at the little monster that was obviously getting excited, and he twitched the corner of his mouth, explaining beforehand: "Even if you have extra energy, you absolutely cannot do more! You can't plant it in the places that are planned later."

"..."

Seeing the disappointed faces of these little demons, Yinla was somewhat glad that he had spoken up beforehand... At this moment, he felt something tugging at his clothes, and he looked at the little fairy who seemed to want to say something but hesitated.

"What's wrong?"

Yinla asked this question.

"Um, Mr. Yinla, you said before that we didn't have enough fertilizer... what's going on?"

The little fairy asked this question, and she could now roughly guess why Yinla was going to such lengths—it was because fertilizer was becoming scarce. She asked, "Aren't there many toilets in the territory?"

Even if there are toilets, the raw materials for fertilizer can't just appear out of thin air, right? Ultimately, people still need to "excrete" it...

"Hmm, do you know how to defecate?"

Yinla asked the little fairy this question, and the little fairy blushed and shook her head, then blushed and nodded... Yinla knew what she meant. She did poop, but because of her appetite and eating habits, she didn't poop much.

After tapping her head, Yinla said helplessly, "Monsters have excellent digestive abilities, and there are also races like the Black Knight and the Headless Horseman who are typical of those who don't excrete, so the amount of fertilizer is far from enough."

With a sigh, Yinla rubbed the little fairy's chin with her finger, and seeing her satisfied expression, said, "Then, let's proceed with the rotation planting according to this plan... You and the other little fairies can arrange the specific areas."

As he spoke, Yinla watched the little fairy fly away excitedly, leading her energetic little monsters away. He smiled, stretched, and then yawned: "Ha~ yawn... Sigh, I'm so sleepy."

Yinla wiped away the tears that had streamed down her face from yawning as she muttered to herself. Although she was very sleepy, she wasn't quite at the point where she could relax... Yinla had noticed this before.

When the little monsters water the plants, they first fetch water from the reservoir. Once the rainwater in the reservoir is depleted, they go to the river to fetch water... which is a very long distance.

Next, Yinla needs to consider the watering issue... Ideally, it should be a semi-automatic on/off water storage system or a direct watering system; digging a canal to divert water is a good option.

It doesn't matter if the mechanical transmission is a bit complex; the main thing is that it needs to be practical.

"..."

So, with the current level of technology in this world... is drip irrigation even possible?
