Axes, sharpenings, adzes, butter and yellow wax, large and small bellows and crucibles from Yangcheng, Shanxi

Although the objects in the workshop have decayed, many of them still retain their original appearance, Liu Yuhao looked at them one by one, and his eyes almost fell to the ground without glaring.

"Is this an underground black factory?"

Liu Yuhao couldn't help but laugh, although those tools are four or five hundred years old, but when they are all put together, Liu Yuhao still knows what they are used for.

Poplar charcoal, smooth sand and Yutian sand are used for abrasives, bricks, lime, etc. are used to build furnaces, yellow sand is used to make mold blanks, and the use of crucibles is simpler.

From this, Liu Yuhao deduced that the utensils in the tomb were actually composed of a lost wax casting workshop.

The lost wax method, also known as the dewaxing method, also known as the "investment method", is a casting method.

In modern precision casting, the lost wax method is called investment precision casting, and this method has been used in bronze casting since ancient times, and its technical principle originated from the incineration method.

The method of the lost wax method is to use beeswax to make a model of the casting, and then fill the mud core with other refractory materials and apply the outer fan. After heating and baking, all the wax molds are melted and lost, so that the entire casting model becomes an empty shell, and then the solution is poured into it in order to cast the utensils.

In modern investment casting, the weight of the casting is generally not more than 50 kilograms, but in ancient times, the lost wax method was used to cast large objects.

There is such a record in "Heavenly Creation, Smelting and Casting", "Where the construction of Wanjun bell is the same as the method of casting tripods." The pit is dug a few feet deep, and it is built like a house, and the mud is used as a mold bone. Its mold bones are built with lime and soil, so that there is not the slightest gap to dismantle. After drying, a few inches of butter and yellow wax are attached to it, and the iron bell is the same as the furnace, the kettle, and the method of plastic.

In history, the use of lost wax casting, its technology to the pinnacle is the Xuande furnace, just Liu Yuhao has a piece in his hand, in order to better understand the exquisite Xuande furnace, Liu Yuhao has done in-depth research on the lost wax method, so you can distinguish the use of those utensils in the tomb at a glance.

It's getting more and more fun!

Although this discovery made Liu Yuhao unable to hide his excitement, at the same time, his head was even more confused.

Some coastal cities do have "underground processing black factories" that use basements to process counterfeit products, but those can only be done in basements after all, and it is the first time Liu Yuhao has heard of moving a lost wax casting workshop to a tomb like this.

What's the matter, King Chuang is also a little talented!

If Liu Yuhao is not mistaken, there should be no infringement in the late Ming and early Qing Dynasties, and there is no so-called counterfeit and shoddy products.

Thinking of Li Zicheng, who later became the short-lived Emperor of Dashun, Liu Yuhao's mind flashed an image of a peasant hero.

In fact, before launching the uprising, Li Zicheng was a laid-off postman. To put it bluntly, before being laid off, King Chuang was originally a "worker" who held an "iron rice bowl" and ate official meals.

Li Zicheng's family was poor in childhood, and he once herded sheep for the landlord and endured all the hardships of life. At the end of the Ming Dynasty, there was a drought in northern Shaanxi for many years, and farmers rose one after another. However, in the sixth year of the Apocalypse, Li Zicheng, who was 21 years old at the time, was just a post guard at Yinchuan Station in Mizhi County.

The task of the so-called post guard is to deliver official documents, escort passing officials and important guests, and transport important supplies.

It's a kind of chore, but the pay is very low, no more than three points a day. In the Ming Dynasty, ten miles of shops and sixty miles of posts were placed, but the public facilities of the post station became a tool for officials to make profits, often to the detriment of the public and private. The already low wages of the post guards are often deducted by corrupt officials.

After all, King Chuang at that time could still eat with his identity as a "big brother worker", but he didn't expect that in the third year of Chongzhen, the imperial court rectified the post station in order to save expenses and abolished tens of thousands of post soldiers.

Just like that, Li Zicheng was laid off.

Who can bear losing their job and having no food?

After being laid off, Li Zicheng was naturally unwilling, and joined the peasant army in anger, "shouting with all his might, Kyushu was split." The most unimaginable thing is that this Li Zicheng, who had worked in the government department and had strong organizational skills, was laid off by the optimized combination, and the team grew to several thousand within ten days.

Rebel? In that era, it would have been over for others, but Li Zicheng, with his indomitable will, turned over again and again, made a comeback, and finally supported millions of troops, occupied Beijing, and announced the demise of the Ming Dynasty.

In Liu Yuhao's books, later generations of researchers respected Wang Li Zi as one of the world's 500 national heroes and one of the world's 15 revolutionary risers......

It is a pity that because he did not correctly confirm the situation and failed to consolidate the hard-won fruits of victory, Li Zicheng's Dashun Emperor was short-lived, and his life ended as a tragic hero.

Such a legendary figure actually opened a "black factory" in a tomb?

No matter what Liu Yuhao thinks, he thinks his inference is a bit funny.

It must be known that Li Zicheng, who was born as a worker, never forgot his true colors, and his character had many advantages such as hardship and simplicity, indifference to wealth, and leniency towards others, and even the "History of the Ming Dynasty" from the standpoint of the ruling class had to record him as follows: "He is not greedy for money and profit, he is not good for wine and sex, he is rough and rough, he lives a simple life, and he shares joys and hardships with his subordinates." Very polite corporal, accepting people's kind words. ”

Think about it, how could such a person with good personal character be so inhuman as to bury thousands of people alive in the ground?

The more Liu Yuhao thought about it, the more he felt that it was impossible.

The intercom was heard several times with the sound of "zla, zl".

But Liu Yuhao didn't care about it, the powerful true qi in the dantian gushed out, and immediately, the two rows of warehouse-like "caves" located dozens of meters away from the "black workshop" were shrouded in his "eyesight" range.

"Hiss"

The ability penetrated the adobe less than three feet thick, Liu Yuhao gasped, and suddenly exclaimed, his face was constantly changing color, and it was extremely strange.

In that storehouse-style tomb, silver is actually stored!

Under the ability, the rectangular silver ingot emits a natural black-green silver rust, and on closer inspection, the surface of the silver ingot shows a gray-brown color, the honeycomb arrangement is natural, and there are golden-yellow multi-colored lights in the holes.

The top of the silver ingot has been engraved with six big characters of "the first year of Dashun Kufu", and the bottom is attached to a thin layer of lead glaze, what is even more frightening is that there is a line of seal carving on both sides of the silver ingot, and the book "silver ten thousand taels" is written.

What stunned Liu Yuhao was naturally not the silver ingots found in the tombs, it can be said that the volume of those silver ingots was unheard of, and they had never appeared in the entire 5,000-year history.

Liu Yuhao roughly estimated that there were ten identical super-large silver ingots stored in each "warehouse", and if those silver ingots were really as huge as 10,000,000 taels were engraved on them, then there were 110,000,000,000 taels of silver stored in the entire tomb.

What is this concept?

At the end of the Ming Dynasty and the beginning of the Qing Dynasty, the hexadecimal system was still used, that is, one tael of silver should be thirty-six grams in modern society, and one hundred and ten million taels should be 3.96 million kilograms when converted into modern measurement methods.

Liu Yuhao didn't dare to count it anymore.

Last time in Hong Kong, Liu Yuhao used a stratagem to get more than five tons of silver from Wu Lingbai, and he had already laughed at Xue Haoran, if Xue Haoran saw this scene, don't laugh at the back of his head?

Of course, Liu Yuhao is not stupid enough to ask for money and die, although the huge treasure of this tomb in the tomb shocked his little heart, but if he was blinded by money and tried to swallow this treasure privately, I am afraid that no one will know how he died in the end.

Money, you can make more money if you don't have it, and if you don't have people, everything will become a floating cloud, this simple truth Liu Yuhao still understands.

In our country, silver has a long history as a currency. It is recorded in the "Historical Records and Pinghuai Book": "The coins of Yu Xia are gold of three grades, or yellow, or white, or red. "Yellow means gold, white means silver, and red means copper.

However, silver became the main currency in circulation, but it was not until the middle and late Ming Dynasty that it was formed.

In that year, after Ming Chengzu moved the capital from Nanjing to Beijing, due to the restrictions of conditions, the Beijing officials' salaries still had to be paid in Nanjing. ”

In the first year of the orthodoxy of Yingzong of the Ming Dynasty, in order to overcome this drawback, the household department decided to change the Jiangnan rent into silver, cloth and other items and transport them to Beijing to distribute official money, and the following year in Suzhou, Songjiang, Changzhou The remaining nearly one million stone grain was also converted into silver to distribute to officials, these decisions of the Ming Dynasty government made silver become the official legal currency at that time, and since then, the financial revenue and expenditure of various dynasties have gradually shifted to silver-based currency payment.

Liu Yuhao still remembered that there was a thread-bound book in the old man's study that specifically recorded the silver standard policy of the Ming Dynasty.

According to the book, in the beginning, silver was mainly divided into three types, one of which was broken silver, that is, less than one tael of silver; The second is the silver ingot, that is, the ingot, the ordinary big ingot is 50 taels and one ingot, the largest has 500 taels, there are many words on the ingot, the big one has the name of the place of casting, the weight and the name of the silversmith, but the small one sometimes does not cast the weight; The third is the silver dollar, which is a silver coin flowing in from foreign countries, mainly in the Fujian and Guangzhou regions.

"Ten thousand taels? It's a shame that Li Zicheng can figure it out! ”

Although the truth is finally revealed, but seeing that such a large treasure can't be obtained, how can Liu Yuhao not be sour in his heart? Naturally, he slandered the buddy of King Chuang, but he forgot that the silver casting of 10,000 taels and one ingot was not original to Li Zicheng, in fact, someone had already started to do this as early as the middle of the Ming Dynasty.

This kind of thing seems absurd, but there is a reason for its existence.
