Chapter 878 Suppression(4000)

"Bronze pillar?"

"Blue liquid?"

Wu Liang really couldn't imagine what kind of thing this was, and couldn't help but frown.

"Yes, this copper pillar is soft. You can leave a mark on it with a light chisel using an engineer shovel. It should be the same pure copper as the bronze statue."

Yang Wanli said in more detail, "As for the blue liquid, I don't know what it is, and I don't dare to teach the brothers to move around. I'll just wait for the young master to check it before I make a decision."

"Lead the way."

Wu Liang still couldn't imagine what this thing was, so he immediately nodded to Yang Wanli and walked quickly towards the place where the copper pillar was found.

"What copper pillar..."

Seeing this situation, all the backbones of the Hu army were also confused and hurriedly trotted to follow.

In this way, we came to the bronze pillar.

Wu Liang first smelled a faint sour smell.

This is a relatively special sour smell that is not mixed with the odor that usually occurs with sour taste, so it is not unpleasant, but it cannot be called good smell either.

"Sir, this should be the smell emitted by the blue liquid. When our people dug out this copper pillar, I had already done a simple check to ensure that these things would not endanger the lives of our brothers.

Then I ran to report to you."

Yang Wanli added in due course.

"Um."

Wu Liang nodded in response and came to the blue liquid that had accumulated about half a square meter and was as deep as a finger.

At this moment, the copper pillar lying across the red soil is still slowly seeping out this blue liquid. This flow rate can be seen that there should not be much pressure in the copper pillar, and these blue liquids are only seeping naturally.

out.

Will this be an artificial pipeline?

Looking at the situation in front of him, Wu Liang first had such a guess in his mind.

Due to limitations of technology and materials, there are no transportation methods such as "pipelines" in this era, but this method is extremely common in later generations, ranging from water pipes, gas pipes, and infusion pipes that are inseparable from life, to some large-scale

In military and civilian infrastructure, "pipelines" are almost everywhere.

As for copper, a relatively malleable metal, if it wasn't too precious, it shouldn't be too difficult to make pipes, even for the ancients...

Of course, this is just Wu Liang's wild guess.

After all, the copper pillar in front of you must have a diameter of at least ten centimeters. Even if it is made into a hollow pipe, if it is only a short distance, it may still be feasible. If it is a long distance... the cost would be prohibitive even in the Han Dynasty.

It has already reached heaven, let alone thousands of years of ancient times, not to mention the pressure and damage that soft metals like pure copper can withstand during transmission.

Therefore, Wu Liang also knew that this possibility was not high, and things were definitely not as simple as he thought...

But this blue liquid with a light sour smell reminded Wu Liang again of his previous speculation about "wet copper smelting".

As far as he knew, the "bile water" used in "hydrometallurgical copper smelting" was a blue liquid, and the earliest "bile water" used in the Chinese dynasty was naturally formed, and could not be chemically produced like in later generations.

method to extract.

In addition, the main component of "bile water" is copper sulfate, so it does emit a light sour smell.

And it is actually very simple to verify this.

Wu Liang now knows nothing about the copper pillars, nor about the blue liquid. He can only verify and eliminate them one by one based on his own guesses, so that he can get close to the truth.

With this thought in mind, Wu Liang had already inserted the head of the engineering shovel in his hand into the blue liquid in front of him.

"this……"

Naturally, everyone in the Hu army did not know what Wu Liang was doing. Seeing this situation, they felt a little nervous. They held their breath and did not dare to ask any more questions.

The shovel head of the engineer shovel was soaked in the blue liquid and did not show any obvious changes.

After a few minutes of this.

When Wu Liang took the engineering shovel out of the blue liquid, the originally smooth surface of the shovel head became as rough as if it had been burned on the part soaked in the blue liquid.

Wu Liang then plunged the engineer shovel into the blue liquid, fished out some impurities from the bottom of the blue liquid that was only a finger deep, poured it on the ground and examined it carefully.

I saw that these impurities contained a few irregular purple-red lumps of metal, the largest of which was only as big as a tooth.

This is elemental copper!

Wu Liang then became energetic.

This is enough to prove that his guess is correct. The blue liquid flowing out of the copper pillar is the "bold water" that can use the "wet copper smelting" technology to refine pure copper!

Although it is still unknown where the source of this "gut water" comes from.

But all previous signs indicate that he has found the right direction, and if this is the ruins of Jiuli Kingdom, then Jiuli Kingdom did not just master the ordinary copper smelting method, but was ahead of the Han Dynasty.

In the Tang Dynasty, the "wet method of copper smelting" can be compared with the Song Dynasty!

This is undoubtedly an amazing discovery!

No one would have imagined that the Jiuli Kingdom in ancient times would have mastered such advanced technology, which will surely once again refresh people's understanding of the ancient times...

After all, "hydrometallurgical copper smelting" has two prerequisites.

One is to have iron, the other is to have courage.

Bile water can be formed naturally, and there are still considerable reserves in some places.

Iron is easily oxidized, so most of it needs to be refined, except for the extremely rare iron nugget.

This is also the main reason why the phenomenon of "wet copper smelting" was discovered as early as the Han Dynasty, but was not applied to the copper smelting industry until the Song Dynasty, because there were records in books related to the Song Dynasty that this kind of copper smelting

It usually takes two kilograms and four ounces of iron to replace one kilogram of copper.

As we all know, human civilization first experienced the Bronze Age and then entered the Iron Age.

Therefore, only if iron tools are widely used enough, and because of the difference in the content of iron and copper in the earth, and the difference in value between the two has widened a lot, will it be worthwhile to use iron to replace copper in bile water...

Since "hydrometallurgy of copper" must use iron?

So how did the Jiuli Kingdom master this technology? Could it be that they have also mastered the iron-making technology?

Obviously not……

If the Jiuli Kingdom has mastered the iron-making technology, then the armors sent out by the Hu army here will not be copper alloys, but should be iron items that have more stocks on the earth and have superior performance as strategic materials.

Therefore, Jiuli Kingdom should not have mastered the iron-making technology, and does not even know what iron is.

It may be just an accident that they mastered "hydrometallurgy of copper".

If they first discovered a large amount of bile, and then discovered iron ore with extremely high iron content, such as the stones on the holy mountain, this might be the case.

Later, they discovered that if such mountain rocks were soaked in bile water, there would be a continuous output of simple copper. Because of its good ductility and stability, the things made of simple copper were naturally better than the pottery of that era.

Much stronger.

Regarding the use of simple copper, they discovered that copper would turn into a hard alloy after being mixed with certain substances, so they made this alloy into weapons and armor, thus replacing the stone tools used before...

Thus, a man with an animal body and human language, a bronze head and an iron forehead, ate sand and pebbles, and defeated Emperor Yan in many wars. The Yellow Emperor's powerful tribal alliance was born!

There is no doubt about the power of Chi You and Jiuli Kingdom!

One detail recorded in the history books is enough to prove this: after the Yellow Emperor defeated Chi You and destroyed the Jiuli Kingdom, the world did not return to peace. Instead, it became more chaotic than before. In the end, the Yellow Emperor had to paint his face like

Because of Chi You's appearance, everyone in the world said that Chi You was immortal, and all the countries in the eight directions were willing to surrender to the Yellow Emperor.

Of course, the Yellow Emperor may not necessarily have painted his face to look like Chi You. After all, Chi You should have been wearing a bronze mask on the battlefield. After killing Chi You, the Yellow Emperor naturally captured his armor. All he had to do was put on the bronze mask.

On the face, in that era of limited information, it was actually easier to intimidate all countries in all directions.

Think these things in your mind.

Wu Liang felt more and more that this copper pillar was not simple. He might be the source of Jiuli Kingdom's "courage" and the source of Jiuli Kingdom's strength. If this mystery could be solved, it would surely open up a new chapter in the history of the Celestial Dynasty.

Chapter!

"Yang Wanli, lead your brothers to continue digging along this copper pillar until it is completely revealed. Be careful this time and don't damage it again."

Looking back at Yang Wanli and everyone with suspicious expressions, Wu Liang did not explain much and emphasized his orders to Yang Wanli.

…

Wu Liang and a group of backbones of the Hu army also joined in the work of excavating the copper pillars.

Soon they discovered more copper pillars underground. These copper pillars were thick and thin, and their shapes were different. Some were just a single pillar, while others had multiple branches. Moreover, they were not in the same shape.

On the same plane, some should be hidden slightly deeper, while others should be hidden slightly shallower.

At present, it is found that the maximum height difference should be about two meters.

However, they all have an unusual feature, that is, the surface of the copper pillars has never developed any patina, and has always maintained the purest pure copper state.

This is incredible.

After all, the bronze statue and the copper alloy armor buried here together with these copper pillars all suffered from inevitable oxidation without exception.
