It's worth mentioning that clay exists in this world, and its production is not low, so pottery jars and earthenware pots are still very common, and there wouldn't be situations where poor people drink water from broken bowls.

However, at a higher level, porcelain and glass are considered extremely valuable items.

Yinla had some prior knowledge of these things, since the Elkaras Palace had always used ceramic cups for drinking water. To be honest, it was quite unusual not to use glass cups.

But he didn't pay much attention to that.

The reason he's paying attention to this now is because he wants to repair the roads in the Demon King's territory. Expanding them could also be seen as preparation for future connections between territories.

Ideally, the best option would be to fast forward directly to things like [railway] or [tram].

However, the world's coal reserves are somewhat worrying, and cutting magnetic field lines cannot generate electricity, so mechanical equipment is completely out of the question.

Mana technology and the like... are things that Yinla can no longer research.

So, as expected, the first step was to pave the road with cement. Building houses with cement would have to wait, as there were too many monsters, so for the time being, they would still live in thatched huts.

The organisms in this world are in good physical condition, so it shouldn't be a problem.

“waaaaagh!”

!

“waaagh!”

!

"..."

Amid the goblins' frantic battle cries, Yinla pondered matters related to cement, but her attention was quickly drawn to the goblins pulling human-powered curved plows across the fields... human-powered goblin plows.

How should I describe it?

These goblins, led by vine ropes, were plowing the land like oxen or horses running at three or even two times the speed... or rather, plowing the land with great joy.

Such scenes allowed Yinla to hallucinate propaganda posters and similar things from her past life in the ancient era, such as "Labor is the most glorious!", which were very shocking scenes.

It's as if labor is truly a joyful thing.

“waaagh!”

!

But weren't you guys yelling "Goblin!" before? Why does it suddenly sound a bit out of place? Although the goblin creature is indeed inspired by the "Greenskins".

Looking at the soil that had been plowed two or three times in a flash, Yinla realized that it seemed to be the time to plant another batch of Blue Qin Gu after the harvest of one batch of Blue Qin Gu... Blue Qin Gu did not seem to particularly absorb nutrients from the soil.

So even though the soil was planted in this way in rotation, it was not turned into a wasteland without nutrients with the help of fertilizer.

...

No, no, cement, cement...

Yinla shifted his gaze from the land and sat in the sunshade where the goblins rested, pondering the cement-making process... He didn't actually remember much, since cement was far less easy to remember than fertilizer, salt, and sugar.

By the way, if we're talking about sugar, the world's mainstream sugar sources are fructose made from fruit and honey from bees... Giant bees used to make perfume don't produce honey because they are carnivorous and more like wasps.

So, if there were sugar, it would definitely be a game-changer for the sugar industry in this world, allowing us to make a killing off the Empire's people and force those sweet tooths to hand over their gold coins.

"..."

No, no, it's cement, cement.

"call……"

Yinla sighed. He realized that he had too many things to do, and if he continued to develop on multiple fronts, he might really be exhausted. He should focus his attention on one thing at a time.

As for cement, Yinla still vaguely remembers... it's made by mixing materials like clay, bricks, broken porcelain, slag, and furnace ash with quicklime in a 7:3 ratio, and using gypsum to adjust the cement's setting speed and quality. All of these materials are finely ground into powder.

The cement formed in this way, when mixed with water, becomes quick-drying cement that can be used for paving roads.

Plaster is a relatively difficult thing to deal with. Yinla is not sure if plaster exists in this world. The ancient textbooks have not mentioned the geographical environment in which plaster is produced.

Fortunately, gypsum is not a necessary component in cement.

As for quicklime, you only need to find rock deposits whose main component is calcium carbonate. Then you can inquire about the mining situation in the kobold territory, or check if there are any suitable stones in the nearby rock piles.

Limestone, chalk, dolomite, and the like are all usable and can be identified with the naked eye, but in this world they might be given a localized name... just like pepper that has been named "Fragrant Grain".

If all else fails, you can choose suitable seashells to burn into lime, and just make sure to keep the seafood shells. However, the yield of this is very small and can only be used for preliminary experiments.

Let's discuss this at tomorrow's morning meeting...

"Lord Yinla?"

After finishing plowing, the goblins who had come back to collect spores saw Yinra and greeted him respectfully... Yes, it was this kind of attitude that made people feel comfortable from the bottom of their hearts.

It's much better than being obsequious.

"Hmm, you've all worked hard. Where's your little devil who manages you?"

As Yinla asked this question, the goblin he was asking looked around, then at Yinla, then at the shed next to Yinla's, pointed, and then, with the spores still attached, went back to his work.
