Daqin: At the beginning, he revealed that he was a traverser, and Ying Zheng was paralyzed

"Reporting to Your Majesty, most of the iron mines in Daqin are inferior mines, including the mines in Yongcheng."

"Throwing in a batch of materials, it is considered as much to smelt [-]% iron."

"Although most of the remaining slag can be discharged, there are still residues."

"With little accumulation, the amount of ore that can be contained in the blast furnace is getting less and less, and the output... is gradually unsatisfactory."

Chen Qing sighed helplessly.

The vast majority of iron ore in China in later generations also relied on imports.

The local inferior mines have low output and high cost, and basically have no mining value.

He has extraordinary abilities, and it's hard for a clever woman to cook without rice.

"Then you boasted that ironware would be cheaper than wild vegetables when you went to Haikou, can it still be realized?"

There was a hint of sarcasm in Ying Zheng's eyes.

Let you rely on your identity as a time traveler to make waves everywhere.

Are you deflated now?

"can."

Chen Qing nodded vigorously.

"Oh?"

"Why are you so sure?"

Ying Zheng asked in surprise.

"Because... Wei Chen has the most outstanding craftsmen in the world."

"With the ability of a humble minister, maybe not."

"But they sure can."

"Even if it's not possible today, in another ten or twenty years, as long as His Majesty trusts them, he will definitely be able to find a way."

Chen Qing answered seriously.

If it really doesn't work, Qin Mo can only build a giant ship and go to Hainan to find the Shilu Iron Mine.

It alone accounts for 70% of the rich iron ore in the country.

The cost of shipping by sea is not too high and should be acceptable.

Ying Zheng said in a deep voice, "I can't wait ten years, twenty years."

"Chen Qing, up to three years."

He held up three fingers and said without refusal.

"promise."

Chen Qing reluctantly complied.

The first emperor is so impatient, there is really nothing he can do.

three years?

Where can I find high-quality iron ore for you.

"Wait a minute, back off."

The first emperor lost his interest in talking, and waved his hands to let the two leave.

Coming out of Xianyang Palace, Fusu saw that he was depressed, and comforted him: "Sir, don't worry too much, Father just said it casually."

"The big deal is to build a few more blast furnaces."

Chen Qing sighed: "It's not about how many blast furnaces are built!"

Seeing that persuasion was useless, Fusu thought for a moment and said, "Why don't we go to the iron smelting workshop? The weather is getting warmer these days, and when the ice on the Wei River melts, the waterwheels will be able to operate again..."

"What did you say?!"

Chen Qing yelled suddenly, startling Fusu a lot.

"Water wheel?"

Fusu asked inexplicably.

"No, no, it's the Weihe River!"

"Your Highness, I found iron ore!"

"Hahaha!"

Chen Qing slapped his head vigorously: "Pig brains! It's all infected by those bastards under his command."

"Walking by the river every day, I didn't realize that this is a big iron mine!"

Fusu asked suspiciously: "Sir...you said the Weihe River is an iron mine?"

"hold head high!"

Chen Qing nodded vigorously: "Not only is it iron ore, but it is also the highest quality rich iron ore! And it saves the trouble of crushing and grinding, and it can be directly added to the furnace for smelting."

"Let's go, no, go back and get the magnet."

He didn't want to wait for a moment, and hurriedly urged the groom.

"Sir, why is it related to the magnet again?"

Fusu was confused and asked in puzzlement.

"Hit the iron!"

"Your Highness, I have discovered another good job."

"A person can lift a hundred catties of iron a day."

"Just look at it."

Chapter 271 Gambling with the Great Qin Salt Administration

The Chinese nation has a long history of using magnets.

According to myths and legends, in the battle between the Yellow Emperor and Chiyou Zhuolu, Chiyou created a thick fog, and the Yellow Emperor built a compass to break it.

"Guanzi Dijiao Pian" records: There is a magnet on the mountain, and there is gold and copper under it.

As early as the beginning of the Warring States period, magnets had become an important tool for making Sinan and exploring iron ore.

Interestingly, ancient Greece discovered magnetite more than 200 years earlier than China, but it was not used at all.

Instead, it was linked to superstition and metaphysics. Scholars and warlocks regarded it as a fetish for curing diseases, and made various necklaces and rings for sale at high prices, attracting nobles and wealthy businessmen.

Chinese ancestors were never ignorant, on the contrary, they were very smart.

Daqin's royal treasury contains rare treasures from all over the world.

There are not only such things as magnets, but many.

Three years later, when the first emperor built the north gate of Afang Palace, he asked the craftsmen to "build it with magnets".

Utilizing the principle of magnets attracting opposites, the world's first "security gate" was created to prevent incidents such as Jing Ke's assassination of Qin from happening again.

Chen Qing happily came out of the inner storehouse, followed by four warriors, who carried a stone-mill-like magnet weighing two to three hundred catties.

"Put it in the carriage."

"Be careful, don't fall."

Fusu pointed to it and said, "Sir, it's true that a magnet can absorb iron, but the iron stone in the sand is not as big as a corn, how much can it absorb in a day?"

"Your Highness, you really underestimate the Wei River outside the city."

Chen Qing shook his head.

It was not until the Ming and Qing Dynasties that anyone thought of using magnets to absorb iron sand from the sand and gravel of the Yellow River and the sea.

The misunderstanding of human thinking is so outrageous.

The iron sand is as small as dust, it is too inconspicuous.

Subconsciously, it will make people think that it can't collect much in a day.

But the fact is that the Yellow River "rolling iron rods" banned by the government in later generations can collect hundreds of catties of iron sand in a day with only one magnet rod per person!

And its iron content is as high as 70% or more!

What's more, if you use a modified boat to drag a large magnet to wander in the river, you can collect three or four tons of iron sand in one day!

What is this concept?

The blast furnace built by Tian Zhou can only produce more than 3000 catties of iron a day.

No matter how slow the wooden boats of the Qin Dynasty are, ten of them are worth one.

Only five fishing boats are needed to meet the daily needs of the Ironworks!

And it also saves the process of gunpowder blasting, manual mining, transportation, crushing and so on.

"Isn't this shit earned by blood?"

Chen Qing talked to himself excitedly.

Fusu shook his head helplessly.

He felt that the other party seemed to have fallen into an inexplicable state of frenzy.

Use a magnet to go to the river to absorb iron sand?

No matter how you think about it, this idea seems unreliable.

The coachman brandished his whip and drove the carriage towards the outside of the city.

The weather was severe and cold, but it couldn't stop the business travellers.

On the Chidao by the Weihe River, there was an endless stream of convoys.

Chen Qing saw many children and old people in ragged clothes, with bamboo baskets on their backs or arms, carefully weaving through the traffic, picking up the manure of cows and horses.

This thing can not only be used for cooking and heating, but also can be used as fertilizer.

The old, weak and weak cannot do heavy work, so they use it to supplement their families.

"This is really guarding Baoshan and begging for food."

"The benefit of rolling iron is a thousand times greater than this!"

Chen Qing said regretfully.

Fusu still didn't quite believe it.

The Weihe River is turbid, and a large amount of sediment has been washed down from the upper reaches.

There are large tidal flats on both sides of the strait, stretching as far as the eye can see.

The old Qin people lived and reproduced again for more than five hundred years. If there is really so much iron in it, how can no one find it?

"seeing is believing."

"How about we make a bet, Your Highness?"

Chen Qing laughed heartily, and directed the coachman to park the carriage on the side near the river bank.

"it is good."

"What are we betting sir?"

Fusu said with great interest.

"Just bet... this magnet can absorb at least ten catties of iron sand after burning a stick of incense."

"If it is dragged by oxen and horses, there will always be five or six hundred catties a day."

Although the natural magnetism is not as magnetic as the artificial products of later generations, it cannot stand up to its size!

The tidal flats along the Wei River have not been touched for tens of thousands of years, and the iron sand content in them must not be low.

"Five or six hundred catties?"
