Brother Ying, please look, this is a coal coking plant."

"A coal conversion process that uses coal as raw material, heats it to 950℃... ahem, a certain high temperature under air-isolated conditions, and produces coke through carbonization, while simultaneously obtaining gas, coal tar, and recycling other chemical products.

"

On the back of the flying squirrel hovering in the sky, Li Yu introduced the function of the tower below to the little girl in palace clothes.

There are a lot of half-white and half-written explanations, and I don’t know how much the third princess can understand. Anyway, she only needs to have a general idea.

Coke was originally made from charcoal: Bai Juyi, the poet of the former Tang Dynasty, wrote the famous "Charcoal Seller". Of course, in his era, just a few decades after the Anshi Rebellion, the Tang Dynasty had long lost its memory.

In the past, during the heyday of Kaiyuan, Xiaoyi was still a prosperous place with thousands of families, and various problems had emerged one after another.

"Coke produced by high-temperature carbonization of coal has an absolute advantage in quantity compared to charcoal. It is precisely because of the large amount of coke that large-scale ironmaking is possible."

The 'Flying Squirrel' mount drew an arc, carrying Li Yu, the third princess, and Winnie towards the ironworks.

Directly below is a railway built in a mountain stream. It was excavated by the alien beast "Li Li", and the sleepers and rails were installed. Then the long carriages were pulled by the camel machine to transport the coke produced by the coal coking plant to the ironmaking plant.

.

"This is an iron smelting plant. In fact, the principle is no different from that of local iron smelting, except that the output and efficiency are higher."

Although Li Yu provided drawings and asked his disciples to make a blast furnace that was quite "scientific and technological," the principle was still the oldest "shaft furnace ironmaking method."

Nie Lan's Nie's blacksmith shop has an 'iron-making furnace' that is half a person's height. The inside is made of refractory clay and the outside is tightened with iron sheets. Iron ore and coke are added, and then the leather bellows are used to continuously blow in the air...

The ironmaking blast furnace built by Li Yu was more than ten meters high, with an all-steel structure. The iron ore and coke were ground in advance, and the windbox was changed into a high-temperature air that was heated in advance and transported by a blower.

So although the principle is still the same, the production capacity between the two is completely the same!

Thanks to the 'gold-smelting and iron-smelting hand' that can produce all kinds of required metal parts, Li Yu can even shape metal out of thin air, otherwise he would not be able to build the tower in front of him even if he had the drawings.

The hot molten iron continuously flows out from the bottom of the blast furnace, making the three princesses in palace costumes shine with splendor in their eyes.

"I once visited the ironworks of the Xicheng family in the north,"

"The Xicheng family built the city in the ice and snow, used lava as the foundation, drove the eagles to make fire, and used craftsmen's methods to melt steel and make iron. Half of the soldiers and armor of the Great Zhou Army came from his family. But -"

The Xicheng family had the national support of the entire Zhou Dynasty, but they could only train five hundred craftsmen and warriors! Most of them were in the middle or lower ranks of C class. The output limit has been locked, and it is difficult to improve; once the personnel appear

Casualties and production will continue to decline.

But the ironworks below were different: the third princess glanced around and found no magic circles, magical weapons, or even warriors, all ordinary people.

However, a group of ordinary people can continuously produce large amounts of iron ingots.

The most important weapon of the country is salt and iron!

"Although Brother Li's methods are neither gorgeous nor magical, they are a broad road for ordinary people."

Although the third princess is young, she has a lot of experience. The workshops run by Li Yu cannot be compared with the wealthy sects like the Xicheng Family in terms of high-end military armor, but when it comes to metal products for daily use, they are unparalleled.

Advantages: huge output, low price, and closer to the needs of ordinary people's lives.

"Excuse me. If the environment of Qianzhong Road was not so bad, I would have planned to make a pot-shaped plow."

Coal, iron smelting, steel-making - this production line can continuously produce steel, plus the 'gold-melting iron-making hand' can rub parts by hand. Next, Li Yu is preparing to mass-produce pot camel machines as various power sources.

Then we began to consider transportation issues with the outside world: as production continued to increase, relying solely on flying squirrels as a means of transportation was already stretched.

"You don't seem happy?"

After carefully visiting several workshops, the third princess no longer had any doubts that Li Yu could feed and clothe tens of thousands of people in Leyuan County and left with satisfaction. Li Yu turned to look at Winnie next to her.

Winnie's personality has always been very quiet, but today she clearly gave Li Yu a feeling of being preoccupied.

"Compared with this third princess, I am still too weak."

Facing Winnie's soft sigh, Li Yu couldn't help but look up at the sky.

"Using her as a standard, ninety-nine percent of extraordinary beings can only be rated as 'weak', right?"

Who is the third princess? The daughter of the Emperor of the Great Zhou Dynasty, the granddaughter of the General Mu Shuai. Not only can the resources of the entire Great Zhou Dynasty be taken away, but at least her share will not be lost, and the various famous masters' techniques are also available.

Needless to say, as long as you have talent and work hard enough, it is not difficult to understand that you will become a strong person.

Facing Li Yu's natural words, Winnie shook her head slightly.

"No, that's not what I meant."

"Stop talking about this, let's go back and prepare the 'happy' potion now."

"good,"

Li Yu nodded, understanding very well that Winnie was eager to prepare for promotion. After gathering the promotion materials, as long as a bottle of magic potion was consumed, he would immediately gain a lot of powerful and brand-new skills... so tempting, it was so tempting to change

Li Yu was afraid that he would have mixed it up and drank it on the spot at the Spider Mountain. He was able to restrain himself until now, and he admired Winnie's "calmness".

————

Leyuan County,

The double-story wooden building located not far from the county government office is the 'home' of Li Yu, Wen Ni, and Fei Shou, and it is also their laboratory.

In Winnie's simple room with only one bed and one table, a crystal cup was placed on the table with 100 ml of pure water in it. Various materials were placed next to the crystal cup. As Li Yu's flying squirrel watched,

, Winnie picked up a black flower.

Black mandala!

This plant has hallucinogenic and paralyzing effects: As Winnie closed her five fingers, the flowers were pinched into a ball, and drops of liquid dripped from her palms. The "bold" squeezing gesture made Li Yu say, "I can make a squeeze."

Juicer's words were swallowed back.

As the black juice drops like ink into the pure water, it begins to spread like threads.

If the black mandala juice is just 'silk', then the second material added by Winnie is the real 'silk': it is a mess of black lines that looks like...

"hair?"

Momonga couldn't help but spoke in confusion, and Li Yu nodded and answered softly.

"Yes, it's the hair."

The enchanting succubus... or as it is called here, is called the 'Occurrence Girl'. It is a spirit created by the resentment of female prisoners. It is a spirit that specializes in seducing men and sucking blood. The second auxiliary material added by Winnie is

her hair.

When the ball of hair fell into the crystal cup, it immediately squirmed as if it came alive. Li Yu couldn't help but twitch his face.

Drinking this stuff really tests one's character.

Next, 10 grams of powder ground from Fenebaud flies and 5 grams of real mummy ashes were added. Although one is a 'fly' and the other is 'ashes', they are actually already processed powders and cannot be seen at all.

Source.

After these auxiliary materials were added, the squirming black hair quickly decomposed, and the liquid in the crystal cup gradually turned into a deep blue, with dots of light shining like a dream.

Finally, a pair of eyeballs and silk glands were picked up by Winnie and put into the liquid at the same time.

At this moment, no water droplets splashed, only the enchanting eyes and the crystal clear silk glands melted silently.

The three colors of black and white, crystal clear, and azure chase each other, mix, and finally turn into pink. In the pink crystal cup, countless grotesque illusions are born out of thin air. In the hazy place, you can see the shining pearls and emeralds, the swaying ribbons, and the colorful clothes.

The clothes, the jade arms are rising, the curves are exquisite, and the beauty is slightly tipsy... At the same time, there are hidden transparent silk threads, and the love threads are knotted, making people indulge in it.

This scene made Li Yu, who was watching, think of a poem in his mind:

The heart is like a double mesh with thousands of knots in it.

"Okay, as long as we are watching, you can rest assured——"

Before Li Yu could finish his words, Winnie had already picked up the crystal cup on the table and drank it all in one gulp!

As the girl swallowed like a swan, the 'happy' potion was taken.

···

"How about it?"

After drinking the potion, Winnie just stood quietly in front of the round table, making Li Yu and Fei Shou wait nervously: Although they had confidence in Winnie, during Winnie's introduction, the potion system was accompanied by

The risk is huge. There are many people who lose control and turn into monsters on the spot after drinking the magic potion.

As time passed by, just when Li Yu couldn't help but step forward to check, Momonga's surprised voice suddenly came from behind.

"Why?!"

The blond animal-eared loli 'flyed' out of thin air.

No, it wasn't that she flew up, but that she was hung up by invisible threads!

The scene he saw when he looked back made Li Yu make a judgment in an instant. He had seen the monster ability of the giant spider. Although his 'gold-melting and iron-melting hand' was very restrained from the invisible spider silk, the flying squirrel obviously had not reacted yet.

What happened over here.

"Don't move, you are controlled by the spider silk!"

As he opened his mouth to remind Momonga, Li Yu turned around and pointed a knife together, blazing flames ignited on his palms, and was about to slash at the top of Momonga's head——

?!
