In tribal culture, the creation of metal devices is really not so easy to develop.

He Zilong felt that even if he traveled to a real primitive society, even if he knew how to build a general method of metal steelmaking, he believed that if he could make a little frown in his lifetime, it would be against the sky.

The ability to use pottery instead of ironware, as an iron pot, and other things, is already the limit of tribal culture.

The premise of mass production of steel is industrial development, and it is industrial development (especially the heavy industry of the second industrial revolution) that generates the demand for steel, which promotes the integration of capital and scientific and technological research. In the feudal era, without the great change of production, without the demand drive of the whole society and the guarantee of science and technology, it is not in line with reality to rely on a group of people to forcibly make a lot of steel.

Not to mention the period of tribal culture!

When He Zilong handed over a large number of pottery to the eldest prince, the eldest prince's eyes were smiling. Someone brought a pocket made of animal skin from behind, and handed it to He Zilong's hand.

"Ah Long, this is what you told me, and the stones of different colors used to exchange pottery ......," the eldest prince said to He Zilong.

He Zilong opened his pocket and looked at those rubies, orchid gems, and gems and ores of various colors (some of which can be finished directly by polishing them), and the smile in his eyes flashed, and he accepted it with a smile.

This deal can be said to be a happy situation for both parties.

In the eyes of the people here, this kind of gemstone ore is useless, and it can be exchanged for practical good things, which is equivalent to picking up cheap for nothing.

Unpolished gemstones can hardly look as glamorous as they were after they were processed. And for the primitive aborigines, it was just a difference in color. In fact, of course, even if He Zilong knew that these were gem ores, but after not polishing and analyzing, he had no bottom in his heart about how much these things were worth.

In addition to being able to distinguish in size and internal purity, the gem ore in hand is probably worthless. There is also a recognized knowledge in the outside world, which can be used as a reference for He Zilong, which is why he asked the eldest prince to give red ore.

That is, in the gemstone world, most of the time, it is the rubies that are the most valuable.

At Sotheby's auction in Geneva, Switzerland, a 25.59-carat Burmese pigeon's blood ruby called "Sunrise" sold for 26.25 million Swiss francs (about 30.33 million US dollars), setting a new record for the price of a ruby.

According to the data of the China Jewelry and Jade Jewelry Industry Association, 1 carat unburned ruby has risen 20 times in the past five years, which is a very high increase in the gemstone category.

Why does rubies stand out among the many jewels and jades?

Of course, the main reason is that scarcity is expensive.

Ruby is a precious natural material, it is a type of corundum, and the main component is aluminum oxide (Al-O-). The red color comes from chromium (Cr), mainly Cr2O3, the content is generally 0.1~3%, and the high is up to 4%. And only red corundum, which is colored by Cr, can be called ruby, while pink corundum is not colored by Cr.

With the exception of ruby, all other colors of corundum belong to sapphires. Therefore, rubies have very high requirements for their color and are non-renewable resources, so the price will show a rapid upward trend.

From ancient times to the present, whether it is a Chinese dynasty or a foreign royal family.

It is impossible for rubies to fly into the homes of ordinary people, and they are basically used exclusively by the royal family and nobles, as a symbol of power, status, and status. When Queen Elizabeth got married, she received 96 rubies from Burmese and a pair of pendants set with rubies and diamonds from the Burmese Women's Liberation Organization. In 1978, the Queen made these gifts into a crown.

When He Zilong put away the gem pocket, the eldest prince also asked all his subordinates to go down, and there were only He Zilong and him, as well as Lan in the house.

After looking around, the eldest prince stepped forward and suddenly asked softly with a serious face: "Long, I heard my sister Lan say that you have some confidence that you can cure my father, that is, the patriarch of our clan, right......?"

"If your father's situation, Helan, and what you depicted without much error, I think the possibility is very high that I try Cheng Leng. Would you like me to try......" He Zilong thought for a moment before replying.

"I won't hide it from you, I arranged Lan to come here to learn pottery on the one hand, on the other hand, she is also my only sister, as long as you are sure to cure our father, then you yourself are our own people, and I will marry my sister to you......," the eldest prince said.

It can be seen that the eldest prince is more anxious than anyone else in his father's treatment. The reason is simple, if the father is well, then he has the best chance of taking over in the future. But if my father is in a coma like this, or if he doesn't wake up, then he will give some thought to many people who have ideas.

"I'll arrange for yours and you to come over and help me bring pottery to my father's floor, and then branch out of other outsiders, but you don't have much time, but the advantage of this is that even if you fail, you won't be in trouble, after all, everyone knows about my father's situation. No one will be surprised even if it is bad, on the contrary, once you succeed, it will be a huge success......" The eldest prince even helped He Zilong think of a way out, and it seemed that he was really anxious.

"Okay, I'll prepare, I'll accompany you over......" He Zilong nodded and agreed.

Then walking back to a place, He Zilong looked around and took out a few things. This is when they came to the underworld, along with a few health kits brought down. According to the situation reflected, it should be some bacterial diseases caused by infection and inflammation, as long as you take some antibiotics.

Soon, under the pretext of sending pottery, He Zilong and his party came to the upper floor of the Babel Tree for the first time.

I didn't expect the space in this to be quite large, and the upper floor was also made into a place like a big room.

Sure enough, the eldest prince had been preparing for this day for a long time, but all the big people who might influence him were not there, and some subordinates also gave him a branch. Then, he gave He Zilong a look.

He Zilong knew what to do, but to be on the safe side. When he took out the medicine box, he still followed the international practice, the method of Western medicine in dealing with acute diseases. Do a skin test first!

After the skin test was fine, He Zilong injected the follow-up potion into it.

Finally, in order to make the effect a little more significant, it is natural to hang the hanging bottle, which is also a supporting item in the medicine box, but there are not many of them. In the process of doing this, he was surprisingly silent!

It's just that the calm on the surface doesn't mean that he is not surprised, for what He Zilong took out, the eldest prince was actually shocked in his heart. It seems that on the surface, he has no expression on his face, but in his heart there are actually turbulent waves.
