Bai Liyan already understands the intentions of Lu Hou today, and now the Yongxing Hou Mansion is a piece of Tang monk meat in the eyes of the world, and everyone wants to take a bite and try it.

If it was someone else, Baili Yan would have to refuse, but it was difficult for him to refuse Lu Hou's proposal.

Luhou is not an outsider, although the harm of the salt barons to the economy has collapsed, the power of the salt barons is still very strong, and it cannot be pushed down, so it can only be co-opted. On the other hand, his Bailiyan's power cannot be pushed down, and if the two strong compete for each other, one will be injured, and both will be injured, and both will be injured.

At present, the interests of the two companies are closely intertwined, and there is no conflict of interest, so there is no reason not to tie this family affair and stabilize the fundamentals.

If he refuses, it is unknown what Lu Hou thinks, the political alliance is definitely not as strong as the blood bond, and there is a danger of being intervened by other families, all factors are considered, the political benefits that can be gained by marrying Lu Hou are far greater than the exclusion of this marriage. But I don't know which of the four daughters of Fang, Xiang, Caiyun, and Xuan did Lu Hou like.

Thinking of this, Bai Liyan's attitude tended to be cautious, and he asked:

"If Lu Hou has something to say, please say it directly, whether the son of Lingzi fell in love with the younger daughter and intended to get married."

"Hehaha...... The old master's heirs are all in Dongyuan and Lincheng, where can they watch the beauties in the mansion from a distance of thousands of miles. Since Yongxing Hou asked, the old man will not beat around the bush. Everyone in Yongxing Simei City knows that Ben Hou wants to be a matchmaker for his grandchildren, but I don't know what Yongxing Hou wants. ”

"I don't know if Lu Hou is hired more or alone?"

Bai Liyan asked, and Lu Hou seemed to be very happy:

"Yongxing Hou said that the children are self-determined, what if you and I might as well have a dragon and phoenix, as long as you are willing to do so, what if you hire more."

"Oh......" Bai Liyan sighed lightly and did not refuse: "Alas, the female eldest is not left, but the younger generation has a word first, and the younger daughter's daughter needs to marry after eighteen parties, only this one, Lu Hou must answer me." ”

"Okay, good, eighteen, eighteen. Come, the old man respects Yongxinghou for a cup. "Lu Hou Dayue, raise the bottle and drink a glass of wine.

After that, the two agreed to hold a "dragon and phoenix meeting" in Bailiyan Mansion in mid-to-late April, when the Marquis of Lu summoned his grandchildren to meet with the Yongxing Marquis Mansion.

However, the stakes are very high, marrying a daughter is like cutting off the flesh in the hearts of parents, Bailiyan still needs to talk to Jiang Rong, Qiao Fu'er, and Xiao Chunyu.

Halfway through the banquet, a fast horse stopped outside the Luhou Mansion, and a soldier was taken to the atrium by the Lufu guards and handed over to Wei Qi.

"Qiqi Wei guard, this is a letter from the Yongxing Technology Department to Yongxing Hou, please Yongxing Hou personally inspect it."

"Got it, stand down."

Wei Qi entered the room with the letter, walked into Bailiyan's side, leaned over and said:

"Master Hou, the test results sent by the physical and chemical room have arrived."

Bai Liyan's expression moved slightly, and he hurriedly asked:

"Oh, where's the list?"

"Here in the subordinates."

"Let's go outside and wait."

"No."

Sending Wei Qi away, Bai Liyan and Lu Hou said:

"The younger generation is abrupt and has some trivial matters, and I hope that Lu Hou will forgive me."

"Well, Yongxing Hou is himself."

"Thank you, Luhou."

Bai Liyan raised her hand to give a slight salute, got up and went out of the house to the world, Wei Qi handed over the letter, Bai Liyan tore open the cover and took out the document, first happy, then surprised.

The good news is that the ore is rich in gold and silver and is completely worth smelting, and the surprise is that the ore contains arsenic trioxide and antimony. The former is arsenic, which is highly toxic to both gas and solid substances, and the latter is less toxic to antimony, but antimony is very toxic, so it is fatal to smelt this gold and silver ore in a simple furnace.

"I say, how can this thief be so generous, it turns out to be so vicious."

"Master Hou, isn't this batch of gold and silver a waste." Wei Qi said.

"For Liang Guo, it is a waste, Ji Feng thinks that my country has a law to refine, or thinks that we don't know the harm, so I want to use this to make a price, first, to poison my country, second, to steal the law of refining, and third, if my country can't refin, and rashly accept its conditions, it will inevitably be a huge loss, and there will be no place to reason at that time, this is a plan to kill three birds with one stone."

Yongxing physical and chemical laboratory has so far extracted and isolated 65 kinds of elements, according to density, chemical valence, physical properties, mineral sources, compound reactions, color reactions and other comprehensive discrimination methods, Bailiyan can identify 51 of the elements, antimony is one of them.

The remaining fourteen elements that had been extracted should not coincide with the earth elements under any special circumstances, but with his knowledge reserves, he was no longer able to distinguish and confirm them, so he had to redefine them in the current language.

Thanks to the development of chemical engineering, the development of geology and mineralogy has made great progress, and Ji Feng wants to use this poisonous minerals to harm him, which is simply a fool's dream.

There are many associated organisms of gold and silver ore, copper ore is a common gold element associated mineral, tellurium, lead and other elements are also associated with gold elements, nickel, tin, lead, mercury are often associated with silver elements, Xianguo Lingshan silver mine is nickel and silver ore.

The most toxic gold ore belongs to the associated ore of poison sand gold and antimonide gold, in which antimonide is often more gold and silver at the same time, and arsenide and antimonide are accompanied by gold and silver ore is really rare.

Liang Guo probably found out that smelting this kind of gold and silver ore was highly toxic after mining, and he was forced to give up mining, but he was unwilling to waste the gold and silver ore accumulated over the years, so he used it as a bargaining chip for Ji Feng in exchange for benefits, which was mostly Ji Feng's last bottom line.

Putting away the letter and putting it in his arms, Bai Liyan returned to the wine table as if nothing happened, and Lu Hou observed for a while and asked:

"What did Yongxing Hou do just now?"

"Oh, it's the king's assignment, and the younger generation doesn't dare to delay, so I have come to ask the Marquis of Lu to resign and enter the palace to repay the king."

"Since it is a matter assigned by the king, the old man will not force the Marquis of Yongxing to stay, and the Marquis of Yongxing will ask for it."

"Thank you Luhou, the junior has taken his leave."

With a deep salute, Bailiyan slowly retreated and went to the palace to return to King Xian.

Ji Feng's condition, Bai Liyan didn't dare to mention it to King Xian, but he was afraid that King Xian was angry and acted rashly.

At this time, it was still early, and King Xian was fishing in Bailing Garden in civilian clothes. Throughout history, there have really not been many kings who have had this kind of elegance. To this end, Bailiyan customized a batch of Taiwan fishing equipment for the use of King Xian. Of course, don't think about carbon fiber rods, stainless steel inserts, and high-strength fishing lines, it's good to have a hand-cranked take-up and rod holder.

"See the king."

"Oh, it's Yongxing Hou here, hurry up and excuse me."

King Xian patted his thigh, he was very interested, and with a little joy in his words, he motioned to Jiang Hao to take a low seat and put it aside, and motioned for Baili Yan to take a seat:

"Aiqing, please take a seat."

"King Xie."

When he was seated, King Xian asked:

"What does Aiqing have to report?"

"King Qiqi, this is the final negotiation on the deal between Ji Feng and my Xianguo."

"Oh...... The widow remembered that Ji Feng had found the widow before, and asked the widow to give him benefits, and the widow sent him to find Aiqing, why, Aiqing agreed? ”

"The minister didn't intend to agree, but Ji Feng calculated the minister, so he couldn't help it."

Bai Liyan explained in detail the ins and outs of Ji Feng's loan and gold and silver ore payment, and King Xian's face really changed greatly:

"Hmph, this treacherous man wants to cheat the benefits of my Xianguo without spending a penny, and the widow has never seen such a brazen person."

"What the king said is that Liang Guo must be thinking that after the war between our country and the country, I will be stuck in the war for a long time and cannot extricate myself, and then the new currency of my Xianguo will depreciate sharply, and the copper coin of Liang will appreciate, and it can be exchanged for the high price of Liang copper coin from the market for my land price of new currency, in order to repay our debts, and finally even if Liang can pay off all of our debts within ten years, but it is not the price of goods that can be purchased with the same new currency ten years ago.

Seeing that his ministers did not allow it, he used poisonous gold and silver ore as a price, trying to spy on the method of extraction of our Xian country, and at the same time poison our country. ”

"In this way, Aiqing is sure to refine gold and silver from this poisonous ore."

"Exactly. Ji Feng also guessed that my Xianguo could dissolve mineral poisons, so he wanted to supervise my country's alchemy in the name of approving gold production, but in fact, he wanted to steal the method of dissolving poisons.

But he didn't know that there were many ways to alchemy, and the minister could use this to deduct gold and silver, even if he had a fiery eye, it was difficult to distinguish the clues. ”

At present, the extraction of precious metals, except for the naturally found camel gold, is basically no different from the smelting of copper, iron, tin, and lead, except for a few elements such as nickel, tin, and lead, most of which are not easy to form compact alloys under natural conditions.

At the same time, due to the difference in the temperature required for the reduction and oxidation precipitation of different elements and oxygen and carbon, the precious metals are smelted at a simple high temperature, and charcoal is added in the smelting process with the difference in the density of the element liquid, and the separation is separated by high-temperature carbon reduction, or blown into the air, and the precious metals are separated from other associated organisms by using the principle that precious metals are not easy to oxidize and make impurity metals oxidize and float.

Through the analysis of the composition of the ore samples provided by Ji Feng, regardless of arsenide, antimonide and ore impurities, the gold content reaches eight coins per stone (about more than 400 grams per ton), and the silver content reaches one and a half cents per stone.

However, arsenide and antimonide are highly toxic substances, and antimony is a toxic substance that is difficult to eradicate, and almost all antimony compounds are toxic, so they cannot be harmlessly treated by conventional chemical smelting methods.

At the same time, the melting point of the two is lower than the melting point of gold and silver of 600 to 400 degrees, and the melting point of the compound is lower, and the arsenide and antimony must be melted first during smelting, and the resulting toxic vapor and dust will envelop a large area, and quickly kill the furnace workers in the core area, and finally get the gold and silver at the cost of human life.

Most of the gold production in Xianguo comes from copper ore, the extraction difficulty is much lower, the content is much lower, the conventional smelting means are sufficient, and there is no need to take physical crushing, chemical washing ore to obtain precious metals.
