Dong Sijiang said in a loud voice: "Our clan has been the lord of the white barbarians for hundreds of years, and we are not afraid of any challenge. No tribe can make more or bigger drums than we do. ”

Guo Ye nodded and said, "I know why your old man is so confident, the best bonanza in the White Barbarian Land has been occupied by your clan. If you really want to compete to make a copper drum, if someone else makes one, you can make two, and of course you are not afraid of challenges. ”

"If only you understood."

"But...... Patriarch Dong, there is one thing you may not know. ”

"What's the matter?"

"There is more than one way to smelt copper in this world, and the method we usually use to smelt copper is called fire smelting copper. There is also a copper smelting method called wet copper smelting. ”

"Wet copper smelting? Haven't heard of it. ”

"It doesn't matter if you haven't heard of it, you can't be alone. Because I just invented this method. ”

Dong Sijiang had an ominous premonition in his heart, and said, "Could it be that you invented this method of wet copper smelting?" ”

"Patriarch Dong is really smart, and he can guess it. Yes, it was Guo who invented wet copper smelting. ”

"Then how is your wet copper smelting better than fire copper smelting?"

Guo Ye said: "It's not much better to say it's good." However, the mineral deposits used are different, and the cost of copper production is lower. ”

This hit the death hole of the Fu clan all at once. No matter how domineering the clan is, it can only dominate all the bonanzas. It would be too much to occupy more mineral deposits.

If what Guo Ye said was true, and he was willing to teach this technique to those small tribes, the leadership position of the Fu clan among the white barbarians would not be so secure.

Dong Sijiang said: "Is King Qin's words true? ”

"Joke, I, Guo Ye, am the Prince of the Tang Dynasty, under one person, above ten thousand. How is it possible to lie? If you don't believe me, I can show you right now. ”

"Then there will be Lao Qin Wang Chitose."

What is the fire method of copper smelting? To put it simply, the copper ore is first crushed and then calcined with wood to obtain blister copper.

As for wet copper smelting, it's even simpler. I have learned chemistry in middle school, and I can replace copper in copper sulfate solution with iron.

The so-called copper sulfate solution exists in the form of bile water in nature. There are many bile water springs in nature, and Guo Ye's wet copper smelting turned waste into treasure, turning these bile water springs into rich ores.

Guo Ye claimed to improve the technology of copper smelting, using this method.

Of course, strictly speaking, this is not much of an improvement. Pyrometallurgical copper smelting and wet copper smelting have their own short and long lengths, and there is no advantage or disadvantage in itself.

It's just that some places are suitable for fire copper smelting, and some places are suitable for wet copper smelting.

Guo Ye came prepared, and in a closed tent, he demonstrated the technique of wet copper smelting very smoothly, and then said, "What does Patriarch Dong think?" ”

Dong Sijiang said: "This seems to be not much better than fire copper smelting, but it is just turning the raw material for copper smelting from copper ore into bile water." ”

Dong Maoshi said: "The speed is not fast, and there are more impurities than fire copper smelting." In my opinion, it's not the same way. ”

Guo Ye didn't argue, and said: "It seems that Guo is really a villain in vain." I will make the technology of wet copper smelting public to the world, and everyone can learn it. ”

"Don't! Other! ”

Dong Sijiang smiled and said: "Although this method is not very clever, it can be regarded as a unique way. It has added another channel for the open source of copper mines. What's more, the cost of this method is much lower than that of fire copper smelting, and it has a great impact on our white barbarians, so it's better not to leak it. ”

Guo Ye said: "It's good for the old patriarch to admit it." Originally, people mainly smelted copper ore, but now they rely on bile water. As soon as this raw material changes, your advantage will not be great. Well, I promise you to keep this secret for now. ”

"Keeping it secret for now?"

"There is no impermeable wall in the world, can it be kept secret forever?"

Dong Maoshi said: "Of course, permanent secrecy is impossible. But being forced to leak a secret and voluntarily leaking it are two different things. ”

"You're worried I'm going to leak this technology out of the way?"

"No matter who leaked it, I'm afraid our clan will be counted on your head."

Guo Ye shrugged his shoulders and said, "And then?" ”

And then ...... Then ......"

Dong Maozhi was stunned for a moment, and after thinking about it carefully, he really didn't have anything to threaten Guo Ye. On the contrary, there are many places to ask for others.

For example, his own secret diseases, such as the confidentiality of wet copper smelting, such as the safety of Bai Man......

Yes, it's Bai Man's safety. Before meeting the Tang Army, Dong Maoshi was dissatisfied with seven and eight was resentful, and even wanted to take the initiative to provoke the Tang Dynasty to prove his military ability.

But after seeing the elite troops of the Tang Army and being shocked by Guo Ye's bow, his idea had vanished. Not only that, but he also thought many times, what if Tang Jun fought under the leadership of Guo Ye? What can I do?

In the end, it was concluded that there was no chance of victory, and there was no choice but to flee for your life!

However, with this escape, the prestige of the Fu clan will inevitably plummet, and with the loss of a lot of copper-rich ore, I am afraid that the Fu clan will no longer be able to say anything in the white barbarians.

Under Guo Ye's rhetorical questioning, Dong Maoshi was speechless for a while, and finally had to say arrogantly: "I don't believe that you didn't ask for our place." Why don't you come to make an alliance with us? ”

Guo Ye said: "Of course, I came to make an alliance with you for a reason. First, the bureaucrats are my people of the Tang Dynasty, and I have the responsibility to bring them back here. Second, the whole world is not the king's land, and the shore of the land is not the king's minister, and I have the responsibility to urge you to worship my Tang Dynasty emperor. ”

Dong Sijiang said slowly: "Whether it is a wingman or Yang Qingqing, you can take it away, not only that, in order to wish you a hundred years of happiness, I also have a big gift for you." As for the Tang Dynasty Emperor, the old man is also willing to represent Bai Man's vassals and offer the largest bronze drum in our tribe. ”

Guo Ye said: "Very good, it is rare for the old patriarch to understand the righteousness so well. On behalf of the Tang Dynasty, I can swear an oath with you to take the land of the White Barbarians as the fief of the Fu Clan, and guard it for generations. In addition, there is also the method of wet copper training and a thousand blue clamps. ”

After a pause, he added, "Guo can swear that he will never teach the technique of wet copper cultivation to other tribes of Bai Man. ”

"King Qin Chitose is really understanding, thank you! Thanks a lot! ”

If Dong Sijiang was forced to surrender to the Tang Dynasty before, and he was a little reluctant, after listening to this condition, he felt that it was worth the fare.

What do you give? One name, no pain or itch. The largest brass drum in the tribe is worth more than 200 yuan.

And what do you get? The technology of smelting copper from wet hair has temporarily freed a thousand blue clamps from the crisis of being subverted. 1,000 blue clamps, worth 5,000 yuan.

One point for pay, twenty points for return.

Is there a better deal in the world? Why didn't you turn this corner before?

Seeing Dong Sijiang's eyebrows and smile, Guo Ye hit the railway while it was hot: "There is a saying called taking precautions." Sooner or later, the technology of wet copper smelting will be known to others, I wonder what your plans are? ”

"Alas, flowers are not good for a thousand days, and people are not red for a hundred days. It has been hundreds of years since the rise of the Fu clan, how can it be prosperous for a long time? If wet copper smelting really spreads widely one day, my family can only respond to the heavens and abdicate to make way for the virtuous. ”

Guo Ye shook his head and said, "The old patriarch's idea is too pessimistic. I have a way, I don't dare to say more, at least I can protect the wealth of the family for a hundred years, I don't know if you want to hear it? ”

Dong Maoshi's eyes lit up and said, "I want to listen, of course I want to listen." Fools don't want to hear it? Say it! Say it! ”

Dong Sijiang is an old man and a slippery man, knowing that there is no free lunch in the world, and said: "I don't know what price my family will pay for this?" ”
