Grandma Gongsun was shocked and felt extremely guilty.
"Grandmother?" Lin Mo noticed that her great-grandmother's expression was a little strange and called out quietly.
Grandma Gongsun waved her hand, and although she didn't say anything on the surface, she had already made up her mind.
We must ensure that the reputation of the Mountain Goddess spreads to even more distant places!
Barren mountains and valleys.
Today, eighty acres of land have been reclaimed in this valley, including fifty acres of black soil and thirty acres of red soil.
The red soil is naturally fertile, so whatever crop is planted grows very quickly, and the grains grown there are sweeter than those grown on black soil.
Therefore, these red soils are usually used to grow new crops. Now, these thirty acres of land are full of sugarcane and soybeans.
These two crops are not new; they were already grown in the land of Liang. However, the seeds bestowed by the Mountain Goddess were of even higher quality, and the crops grown from them were also very pleasing.
Le Bai twirled the soybeans in his hand and couldn't help but sigh, "Even in modern times, we don't have such good seeds. If we pressed oil from freshly harvested soybeans, it would definitely be top-grade oil!"
Unfortunately, the ancient oil pressing methods were too primitive. They not only required a lot of manpower, but also had a low oil yield, and the pressed oil was cloudy and needed to settle before it could be used.
"These soybeans would definitely make delicious tofu, dried bean curd sticks, and all sorts of soy products," Zhang Yao thought, glancing at the food and starting to reminisce about the tofu pudding and handmade spicy chips she'd had before…
"And there's sugarcane. This sugarcane is of very high quality. It's crisp, sweet, and very juicy. Not only can it be eaten as fruit, but it can also be used to make sugar. With so many people in this barren mountain area, we consume a lot of sugar. Why don't we find another group of people to make sugar?"
Zhang Yao misses the pure sugarcane-based brown sugar. Every month when she has her period, she drinks a cup of brown sugar ginger tea or boils a bowl of brown sugar egg tea, which makes her feel warm all over.
"But how exactly are oil extraction and sugar production done?"
She scratched her head and asked her sister in her mind, but the sister didn't know either.
As modern people, they buy whatever they need. They can buy white sugar for just a few dollars. Who would bother to study how sugar is made?
But they had some impression of salt, such as sea salt, lake salt, well salt...
These methods can all be used to make salt, but how do you make sugar?
Everyone looked at Gu Rui behind them, since this guy had given them instructions on building the kiln and making bricks, so he should know a little about oil pressing and sugar making, right?
Seeing everyone's gaze, Gu Rui subconsciously wanted to adjust his glasses, but the empty feeling reminded him that he had already transmigrated and his vision had returned to normal, so he naturally didn't need to wear glasses.
He first shook his head, then nodded: "Actually, I don't know the methods for pressing oil and making sugar, but any tool is inseparable from mathematical principles."
"Take the steam engine, for example. Even though it was only made in the industrial age, as long as we know how it works, we can make a primitive version of the steam engine using bronze, leather, animal fat, and pistons."
"Other tools operate on the same principle. In ancient times, oil pressing was generally done manually or with levers. However, if we want to reduce manpower and improve the quality of the oil, it's not impossible. We can use Archimedes' principle to create a screw press. This machine is more efficient than levers and can be used not only for oil pressing but also for brewing wine..."
"Of course, movable type printing can also use a screw press to apply pressure evenly; this kind of machine can also be used in printing..."
"Next is sugar production. The Liang Dynasty already has rock sugar, but it contains many impurities. If we want to separate the impurities, we can use centrifugation..."
Gu Rui didn't say much, just briefly explained a few principles, and the people around him seemed to be thinking about it.
Everyone understood, except for Xia Yan, who was involved in magic, who was completely confused.
She was just a liberal arts student before, how would she know so many mathematical principles!
But to avoid standing out, she coughed and said, "These principles are indeed very practical. If you need magical help, just tell me. The magic here in the barren mountains is quite abundant."
"Some things can be replaced with magic!"
Xia Yan blinked.
She only brought up magic because she didn't understand it.
However, they found that the people opposite them were suddenly startled.
Gu Rui: "Yes, the technology that can't be done in this era can be completely replaced by magic or various abilities!"
Xia Yan was even more confused. Magic combined with science? How could that be combined?
