"Second brother, in fact, the big man will be very powerful! Really, soon, the people will be rich! ”

"It will be strong for many, many years!"

"Hahaha, you're right!"

Liu Ying hugged Liu Chang and pinched his face.

"I'm serious!"

"I know, I know."

The largest mines in the Han Dynasty were in the Zhao Dynasty, and the rest were distributed in Yan, Liang, Shu and other regions.

This mine in Shangjun is not the largest mine, but it is the closest government-run mine to Chang'an. After the founding of the People's Republic of China, Xiao He sold some of the large minerals left by the original Great Qin, leaving only a small part, because the Han Dynasty was not such a criminal, and Xiao He was never willing to abuse the people's power.

Among the current hundred officials, the most famous among the people is Prime Minister Xiao He, and the people everywhere love him very much, and he is even more excited to meet the Prime Minister's frame than the frame of the Son of Heaven. Xiao He continued the procedural law of the Qin Dynasty and put the last power on himself, but if the people felt that Shangguan's judgment was unfair, they could sue Xiao He all the way.

Of course, if it is found that the superior has not misjudged, then the person will be doubled, but if it is really false, then the chief will seize the punishment he had sentenced to the first time.

In addition to litigation, in terms of taxation, Xiao He also lowered taxes many times, abolished many miscellaneous taxes left by the Qin Dynasty, the early Han Dynasty, is still a classical JG country, everyone has a title, and they can improve their titles by fighting wars and beheading, but on this basis, Prime Minister Xiao Cheng has increased the proportion of agricultural promotion, and strives to make the Han go in a different direction from the Great Qin.

Shangjun is probably one of the poorest counties in Dahan, where there are few county seats, the roads are bumpy, and the county seats are far from each other.

But the mining field, is still relatively lively, although there is no city, but because of the mining, there are some villages around, merchants can rest here, they also provide some food, drink, and there are merchants who buy iron tools will trade here.

Liu Chang couldn't wait to follow his second brother to the mine to visit.

The mines of Dahan are still relatively simple, and the miners still rely on the most primitive tools, using axes, hammers, hoes, etc. Around the mine, you can see many furnaces of different sizes. For convenience, in the Han Dynasty, iron smelting and mining were in the same place, mined here and refined there.

Liu Chang hurriedly jumped up and began to observe seriously, because there were no tools, the miners could only look for ore by observing with their eyes, using simple tools to determine the ore grade and determine the direction of mining.

"Awesome!"

Liu Chang couldn't help but sigh, he thought that the mining method at the moment should be very simple, but in this mine, the miners used a combination of vertical shafts, inclined shafts, inclined roadways, and flat roadways, and even knew how to solve a series of complex problems such as underground ventilation, drainage, lifting, lighting and derrick support.

In terms of methods, they have done it to the extreme, and the only thing that can hinder them is the mining tools.

Liu Chang squinted his eyes, as if he remembered something, and lowered his head to think.

Liu Ying came to the mine for the first time, he couldn't understand anything, whether it was the ore or their various methods, he just looked around blankly, and didn't bother Liu Chang. The prince himself arrived, and the miners all knelt in the distance, bowing their heads, and the armorers stood beside them, bowing their heads, not daring to look directly at the prince.

And the person in charge here is a guy named Zhao Huan, who looks rough, but his mind is lively, with a smile on his face, standing beside Liu Ying, "It's really a blessing for us that the prince can come in person... The minister can see the prince in person, and he will die without regrets... The benevolence of the Prince... Everyone knows it..."

Although everyone Liu Ying met on weekdays was also very polite, he had never encountered such a straightforward sycophant with no lower limit. After all, Liu Ying is surrounded by some people on weekdays, and they will definitely not be so direct in their sycophants, they still want to be faced.

After a while, Liu Chang suddenly walked over.

"Do you know the method of burning and exploding?"

Zhao Huan was stunned for a moment and asked, "What is the burning and explosion method?" ”

"First use fire, heat the ore, then pour cold water .... If the heat expands and the cold contracts, the ore will burst..."

Zhao Huan's eyes widened, he had never heard of such a way, what nonsense is this little cub talking about here?

He looked at the prince with some suspicion and asked, "Who is this..."

"This is my seventh brother, chief."

"Oh, it turned out to be the head of the son, I have heard of the name for a long time, and it is a great fortune for the minister to meet the son today, and the minister can actually see the prince and the son one day..."

Zhao Huan said, turned around suddenly, and yelled at his subordinates: "Didn't you hear Gongzi speak!" With the explosion method!! ”

Liu Ying carefully pulled Liu Chang and asked in a low voice, "Eldest brother, can this really work?" ”

"Of course, it's the easiest way..."

Zhao Huan personally took the miners in an open-pit mine to do what the boy said, Zhao Huan probably didn't believe that this method would work, but when they burned the iron ore red with fire, and then splashed the water violently, "Hiss~~~~~", the ore actually cracked, Zhao Huan's eyes widened, and the iron ore fell with a light chisel with an iron hoe.

"It's... This..."

Zhao Huan was dumbfounded and looked at Liu Chang in disbelief.

Liu Ying also looked at this scene in surprise, and then he laughed and rubbed Liu Chang's head.

"I knew it! The eldest brother will not let me down! ”

Liu Chang didn't look very happy, he shook his head and said, "This method can have little effect, the best way is to use gunpowder to blow it up..."

"What medicine?"

Liu Ying thought that he had read a lot of books over the years, and his knowledge could not be said to be profound, and he was definitely not too ignorant, but now he realized that he still did not read enough. He couldn't understand what Liu Chang said.

"Brother, do you know where saltpeter is?"

Zhao Huan, who had been waiting for the opportunity to pat himself on the side, heard this, his eyes lit up, and he was about to speak, but he heard Liu Ying say confidently: "Saltpeter is out of Longdao!" ”

"There's probably saltpeter here, too, right?"

Zhao Huan smiled and nodded, "Of course there is, but why does the son want saltpeter?" Isn't there anyone who is suffering from a disease? ”

Liu Chang didn't answer, and asked again, "What about sulfur?" ”

"What's that?"

Zhao Huan looked dazed, he had been mining for so many years, and he had never heard of sulfur.

Liu Chang reluctantly described the characteristics of sulfur for them, Zhao Huan thought for a moment, his eyes lit up, and he was about to speak, Liu Ying asked with a smile again: "You are asking about Shi Liuhuang, right?" ”

"It's not that hard to do..."

Zhao Huan looked at him with some grievances, and asked curiously: "The prince has lived in the palace for a long time, how can he know this?" ”

Liu Ying said: "I am a good reader, I once read a book "Fan Zi Jiran", which is written by the ancient Fan Li, which contains saltpeter, stone flow yellow and other things, listening to the eldest brother mentioned, I thought of the introduction in the book..."

"Alas, knowing the world without leaving home is the power of books! The prince is smart, and the ministers can't wait..."

"Then this stone is yellow, can you get it?"

"We don't lack anything in Shangjun, but we don't lack the two things you want, Son."

Zhao Huan patted his chest and said that he would be able to send these two things to Liu Chang's hands today.

"Also... One more thing... Charcoal, which was also brought to me. ”

"Good!"

Zhao Huan left in a hurry.

The bronzes of the Shang Dynasty have begun to use charcoal as fuel, and the time of using charcoal in China is very early, the wisdom of the ancients.

The miners also started working, and in many places they began to use the explosion method, but it was still better used in open-pit mines. Liu Ying followed behind his younger brother, and he asked with some confusion: "Eldest brother, where did you learn these strange methods?" ”

"Who taught you how to build a spinning wheel before, and now you have come up with such a method in an instant?"

"I was born to know."

Liu Chang raised his head arrogantly, "This is nothing, later, brother, you will know how great my ability is!" ”

"Could it be that those three things can be used for mining?"

"Want to know?"

"Then take me to dinner, okay.... I'm hungry, I'll tell you when I'm done. ”

ps: It's going to be on the shelves tomorrow, bury yourself in the manuscript, and let everyone see it at a time tomorrow.
