The emperor is the lord of all nations!

Only when all people exist can there be an emperor above millions of people. As an emperor, only by benefiting all people can we gain the support of all people.

The emergence of sugar was not only because Ying Zheng wanted to support the Royal Chamber of Commerce of the Great Qin Dynasty, but the most important purpose was to benefit the people. Potatoes and sweet potatoes were too far away, so he could only buy them step by step.

He wanted to change the eating habits of the people of the Qin Empire. Ying Zheng knew that at this time, the way of making meat was too unexpected and completely different from later generations.

The practice of meat eating in this era was too primitive. One of them was that "roasted" was basically unchanged. From the composition of this word, we can understand that the meat was roasted on the fire.

Although "fried" has the same name and different realities. It means pouring meat sauce on the rice and adding paste to heat it; "cooking" is also different from later stewed meat, instead of adding any seasonings, boiling large pieces of meat or even whole pigs and sheep in white water.

The utensils used are cauldrons and cauldrons that appear very frequently. Cauldrons are generally round and have three feet under them. They can be ignited under the cauldrons and heated; cauldrons do not have feet, but they have two ears that have the same handles that can be hung up and hung in the air.

The other methods are all made of raw meat. Often referred to as "roasted" is "sashi", which means cutting raw meat into slices and dipping it in seasonings. Fish sashimi is the predecessor of Japanese sashimi.

Therefore, the popular literal meaning can be understood as finely chopped barbecue everyone loves to eat.

There are several other methods, which are to remove the blood vessel tendons of the raw meat, chop or mash them, and then add various seasonings to marinate or mix them: "stain" means to put the meat in wine and marinate; "boil" means to make the meat into meat floss;

"水" (hǎi) is to make meat sauce; "水" means to cut the raw meat into strips, marinate it and then air-dried it, which is also called "水".

...

Such a situation must be changed, after all, it was claimed to be a foodie empire in later generations. Of course, the reason why Ying Zheng was concerned was because raw meat was unhygienic.

Moreover, most of the food in the Qin Empire did not have much flavor. Even in this era, only the royal family would grind the noodles with grain.

The rest were steamed after removing the grain and eating it. Ying Zheng had carefully sorted out Li Kang's memories, so he hated these things deeply.

It is just that the most important thing in the Qin Empire was never to eat but to survive, and this problem had to be left behind until today.

So iron tools must be released!

Only when iron tools are released can all change. The emergence of iron tools, coal mining, wars break out, and the introduction of rice, corn, potatoes, etc. in Chameng can the Qin Empire undergo a complete change.

Therefore, the most important and urgent task is the development of iron smelting technology.

At this moment, Ying Zheng's thoughts flashed. After a moment, he couldn't help but look on the huge map of the Qin Empire in his study. He knew in his heart that outside Longxi County, there was the West Sea and a large number of salt lakes near the West Sea.

To the north of the West Sea, there is a huge iron ore vein on the territory of the Great Yuezhi, and in Pingcheng, Yanmen County, there is a huge coal ore vein.

And all of this is a divine object that changed the Qin Empire.

With all kinds of thoughts in my mind, Ying Zheng looked at Gongshuqiu at this moment, and said in a quiet tone, "My husband, how about the iron smelting technology in the Daqin Shang Workshop?"

"Can iron tools be made beyond bronze tools?"

Ying Zheng knew in his heart that the Qin Empire must transition from the Bronze Age to the Iron Age, and whether it is mining coal or iron ore veins, it requires iron tools.

At this time, he could only ask Gongshu Qiu.

Hearing this, Gongshuqiu was silent for a while, and headed towards Ying Zheng, saying: "Your Majesty, the bronze smelting technique in the Central Plains during the Shang and Zhou dynasties had reached a considerable level, but from the mid-Shang Dynasty to the weekend for hundreds of years, artificial iron smelting technique did not develop under the influence of superb copper smelting technology. When I occasionally saw artificial iron smelting tools on the Western Zhou Dynasty, I still used meteorites."

"Because I, Daqin, has never had large iron ore veins to mine, and the same bronze weapons have been used because of the immaturity of iron smelting technology."

"In the process of annexing the six countries, Shanggongfang absorbed some craftsmen from the courts of the six countries, and then further developed iron smelting technology."

Speaking of this, Gongshuqiu had a deep gaze and bowed to Ying Zheng solemnly, saying, "Your Majesty, after many tests at Shanggongfang, the weapons made of pig iron have high hardness and toughness, rich raw materials and low prices."

"Now, Shanggongfang has mastered the characteristics of pig iron that are hard and wear-resistant, but pig iron is brittle and not resistant to bumps."

"In order to overcome these weaknesses of pig iron tools, Shanggongfang optimized the invention of cast iron annealing technology."

"Annealing technology reduces the brittleness of pig iron and improves its toughness. It is used as a raw material for weapon casting to make the weapon made with a sharp edge."

"At the same time, the cast iron decarbonization steel technology is integrated, which maintains the advantage of less pig iron inclusions, has a uniform structure and a pure texture, and can be used for the casting of weapons."

...

After hearing Gongshu Qiu say this, Ying Zheng nodded. At this moment, he also knew that the Great Qin Shang Workshop only integrated the development of iron smelting technology in the Central Plains over the years.

Not going further!

Ying Zheng knew in his heart that the defects of pig iron were too great, and the weapons of the three armies of the Qin Dynasty had already become stronger for the farm tools of the people of the world.

What's more, he knew that there were many coal veins in Pingcheng, so that they could have enough high temperatures to forge iron veins.

At this point, if Ying Zheng Development mined the coal mines in Pingcheng, it would be possible to promote the steel speculation method in this era.

Ying Zheng had a certain impression of the method of stir-frying steel. He organized some words in his mind and said to Gongshuqiu, "If my husband heats the pig iron to a melting or basically melting state, fry it in the molten pool, and use the oxygen in the air to oxidize the carbon contained in the pig iron, thus becoming steel or cooked iron."

"In this way, the utilization of iron ore veins will inevitably be improved. If steel-fried and steel-fried iron become the most important materials for making iron tools, especially weapons and production tools, this will be a great help to the Qin Empire."

Speaking of this, Ying Zheng paused slightly. He knew in his heart that what he said was too advanced and Gongshu Qiu might not understand. He was silent for a moment and said.

"When the pig iron is processed into cooked iron, or hard, the raw materials are heated and forged, squeezed out impurities, improved tissue, carburizing and improved stiffness, and then made into objects; mainly by repeated heating and folding forging to improve the quality of the final product."
