I am a nobleman in Spring and Autumn

Chapter 8 The Tech Tree That Is Hard to Light

After Zigong decided to be Zhishi's retainer, he needed to show his talent.

In this way, Zhiyao found that Zigong was not only good at business, but also very eloquent, especially in management and other affairs.

Sounds like right?Doing business itself involves many aspects. Without flexible and sharp thinking, a mouth that can speak well, how to conduct business negotiations with people and sell one's own products.

If you want to make your business bigger and stronger, how can you lack proper management?
As for the observation of the pattern, where are the products needed, which products can be sold best, and where to obtain the greatest profit, it is necessary to have sufficient vision.

"It's a big profit!" Zhiyao was so happy.

However, Zhiyao knew that Zigong would not be a retainer of the Zhi family forever, and it was hard to say how long he would stay.

Zigong himself is an aristocrat, otherwise it would be impossible to make the business bigger and stronger.

It is not yet the Warring States Period. Many businesses require a certain status to do. For example, to do business, you must have a noble status. The reason is that non-nobles have no real property.

Constant property is land, labor and resources, which means you need to have fiefdoms and subjects.

Of course, because of the late Spring and Autumn period, too many countries were destroyed. Some nobles from the destroyed countries lost their fiefdoms, and those who fled to other countries had to earn some income in order to survive. Many nobles who lost their fiefdoms chose to join other nobles as retainers. Part of it is to manage other businesses, and most of them are living on their laurels until they die.

Those nobles who choose to manage other businesses generally choose to be "cargo porters" in the pure sense...that is, they no longer produce their own goods, but buy goods from nobles and transport them to other places for sale. They are the earliest second-class dealers in Zhuxia .

In fact, it is very reasonable for the nobles who lost their fiefs to become the earliest Erdao dealers in Zhuxia. When they fled, they brought money with them, which is equivalent to having original funds.Originally, aristocratic origin representatives would have some connections, and nobles always need to give some face to their peers before they can purchase supplies; like ordinary Lishu, even if they have their own private property, they will have very little, even if they have money, it is not enough How to do business operations when purchasing bulk from the nobles?

After Confucius left, Zhiyao asked Lao Tzu and Zi Gong to teach her schoolmates, while she went to do other things.

The state of Jin is surrounded by mountains on many sides, and its geographical location is a mixed bag.

Mountainousness means that there are dangers to defend, and mountainousness means that the area that can be used as arable land is reduced. If it is not good or bad, what is it?
Another point is that the land in Jindi is not fertile, and the environment in the northwest and northeast is still very bad.

In the northwestern part of the Jin Kingdom, the soil salinization in the "Huo" and "Pu" lands is really serious. Let alone farming, the grass doesn't even grow a stubble.The salinization of the soil here has been improved, and we have to wait for the Yellow River to change its course and wash it away.

And the northeast is a wetland, where floods often occur, swamps can be said to be everywhere, and there are so many beasts, snakes and ants that it is scary.

What is more terrible is that the northeast of Jin State belongs to the fiefdom of the Zhi family, and what is even more terrible is that the area called Taihang Mountain in later generations is also the fiefdom of the Zhi family. Although the fiefdom of the Zhi family seems to be quite large, it is actually Difficult-to-develop sites accounted for the majority.

Of course, it's useless to Chunqiu people, Zhiyao doesn't think so.

Just say the Taihang Mountain area?People in Spring and Autumn became confused when they heard about the continuous mountains, thinking that the resources are only trees and various animals that can be hunted; Zhiyao knows that there are quite a lot of high-quality coal mines there, as well as copper and gold mines that are currently very precious , iron ore resources, molybdenum ore and tungsten ore that are temporarily unused are also abundant, not to mention various Chinese medicinal materials.

Zhiyao plans to first understand some smelting technologies on the "Father Huang" side, accumulate enough technology, and then go to the Taihang Mountains to set up a production base.

There are many open-pit coal mines in Jin. People in the Spring and Autumn Period know that black stones are easy to ignite. They know that if they smell too much black stones, the smoke will be poisonous. The ancestors taught them not to light black stones.

"Smelting iron to build a furnace, which looks like a pot..." Zhiyao is actually not very good at it, so she tried to explain it more clearly with limited knowledge.

He was talking about a shaft furnace. In fact, there is already a related technology at present, which is no different from smelting copper ore.

The transferred craftsmen from the Zhi family have relevant skills. When they were doing things, Zhiyao started to watch from the furnace building, because Zhiyao didn't know much but just watched, and seldom gave advice.

Of course, iron smelting has been known, but iron was not popular in the Spring and Autumn Period because it was too brittle and easy to rust.

What Zhiyao needs to figure out is the quality of the iron, instead of studying how to smelt iron from scratch, and how to produce iron ingots, he doesn't have to worry about it.

Another point is that using coal for heating is Zhiyao's first initiative, otherwise the smelting is actually heated with charcoal.

Zhiyao, who knows a little bit about experimentation, didn't care about killing people. Before the experiment, she prepared a mask, and the second thing was to prevent people from getting too close to the stove.

After the first experiment, Zhiyao clearly saw the shortcoming of being very brittle, and probably knew that the sulfur content was too high.

In fact, the current iron has the same problem, even if coal is not used, it will also have the disadvantages of being too brittle and lacking in toughness.

"I remember whether to use horse urine or lime powder to solve the problem of sulfur content?" Zhiyao decided to ask the craftsman to try horse urine first.

If the horse urine cannot achieve the desulfurization, Zhiyao can only send people to get lime powder.

As for the lime powder, you can buy it from the Wei family, and the people from the Zhi family can also get it from the Taihang Mountains.

The reason why the Wei family has lime powder is that there is a Huotai Mountain in their "Lv" land, which is also a place with many open-pit coal mines and limestone.

Later, Zhiyao discovered that desulfurization procedures are also required to use coal, and suddenly found that it is really difficult to accomplish one thing.

Another point is that Zhiyao understands how difficult it is to liquefy iron only after a real experiment.

In fact, the melting point of iron is 1534 degrees, that is, the temperature at which iron liquefies is 1534 degrees.

Therefore, the requirements on the furnace are beyond imagination. If the furnace is not suitable, and the coal has not been scientifically processed, the coal combustion temperature is only about [-] degrees.

Zhiyao probably understands the basic common sense, that is, coking coal is used in modern steelmaking. Ordinary coal cannot be directly used for steelmaking, and must be coked and washed.

After the first batch of iron was smelted, what Zhiyao saw was sponge iron.

The production process is a layer of coal, and then a layer of iron ore, and then paste it with mud, and slowly burn that kind of iron to produce it.

"So... don't even think about steelmaking, or try to bring the relevant technology to the level of the Western Han Dynasty?"

After being busy for nearly a month, Zhiyao is a little frustrated when she comes to such a conclusion, but she will never be discouraged.
