If the technological point of metal casting appears, it will mean the official mastery of higher-level forging methods, such as modular casting. While building a workshop, it will greatly improve the efficiency of the smelting and melting of various instruments, and even Precise and exquisite bronze ornaments can be cast, thus officially announcing that it has entered the next era.
Of course, if the workshops and forges can operate normally, population and productivity are also necessary conditions.
Eureka ascends.
Yuzai told Guangchengzi that in his southern territory, there were many skilled craftsmen, including some legendary craftsmen, who could make many wonderful and delicate instruments.
Guang Chengzi suddenly frowned.
"Yijun and Danzhu? Yijun, I know, the earliest Qiaochui, a great craftsman praised in the world, I am a little interested in him, but not much. As for Danzhu, a carpenter, even if it is Di Fang Xun’s eldest son, what does that mean? How can a junior be on par with me?”
Guangcheng heard that Danzhu was the empress's master craftsman. Guangcheng said angrily: "A man will not be ranked with Ahong after all!"
Guangchengzi looked down on Danzhu and thought that Danzhu's craftsmanship was not worthy of being compared with him. Moreover, Guangchengzi felt that he had transcended masonry and carpentry and reached the professional level of a metalsmith. How could he be compared with him, a small carpenter?
However, Yu Zai cited several examples, all of which were things that Danzhu helped produce. After hearing this, Guang Chengzi frowned deeply and felt a little suspicious.
But he quickly said: "What can be built with wood and stone, gold and copper can also be built..."
"Boy, you want me to go to your territory with you and help you work? Yes! As long as you worship me as your teacher, everything will be easy."
Guangchengzi suddenly spoke and looked down upon Yuzai.
You kid, I’ve lived for more than a thousand years, what kind of tricks have I not seen?
If you want me to work for you for free, just ask, but the price is not low.
"Do you think I'm interested in what you're talking about? If you don't accept me as your teacher, I won't follow you."
Guang Chengzi stared at Yu Zai. At this time, everyone was back on the road. Yu Zai laughed, and the atmosphere was a bit awkward.

The oldest melting and casting method is often considered to be the lost wax method. However, before the lost wax method, in the Shang Dynasty, a longer and more efficient method had already appeared. This method is called the lost wax method. The technical principles of law are derived from its progress.
Burning loss method, also known as lost mold casting or lost rope casting.
Using rope as a mold is an integral casting process, often used for casting bronze objects. Its main function is to make objects without mold lines. When making molds, materials that can be burned and disappear are used as molds. On the outside of the whole After the mold is made, the incinerable mold and the mold are fired together, and the mold will be burned to ashes. After removing these ash, you can get a whole casting without divided planes, which is called a mold. If you use this kind of mold to make castings, there will be no mold lines.
.......
Western Wasteland, Xunwu Mountain, beyond the source of the Wei River.
There is no vegetation in this mountain, but there are many gold and jade. There are many wild beasts in the mountain. In the nearby mountains, Zhu Yan lives. This strange beast looks like an ape, with white head and red feet. When it appears, a great war will break out in the world.
The people of the Dihong clan arrived here temporarily to rest and wait.
Emperor Hong himself was in a copper-smelting earthen house.
Last time in Kuangji Mountain, Di Hong found the mold left by Yu Zai, so after careful study, he figured out something.
The metal is smelted into a liquid that meets certain requirements, and then poured into a mold. After cooling, solidification, and cleaning, a casting with predetermined shape, size, and performance is obtained.
Eureka ascends.
Many technological points are opened by accident, including picking up missing items.
The crucible is smelting copper ore...
loading……
After several hours of burning and Master Dihong's busy work for a long time, the copper ore was melted into copper water, and then the copper water was poured into the prepared mold.
Data continues to be loaded...
Finally, after a long time, while busy, I seemed to see the shipment of some kind of treasure that I kept refreshing.
Looking at the molten copper ax in front of him, Di Hong stretched out his hand. The craftsmen around him were shocked and tried to stop him, but Di Hong ignored them.
As Di Hong's hand touched the copper ax, a cold breath gathered, and the red copper ax, which was originally in a high temperature state, instantly began to cool down.
In Di Hong's palm, vitality surged, and his methods were unparalleled. The craftsmen around him stood upright, watching this scene without daring to speak.
Di Hong touched the finished product. There was still a big gap between the ax and what he expected, but at least this time it was a complete success.
And even if this ax cannot be used as a sophisticated weapon, it is definitely very useful for farm work.
He is not a fire wizard, so he cannot rub molten iron with his hands like Yu Zai, but even if he is a fire wizard, he rarely has the same methods as Yu Zai.
What Di Hong is currently learning and exploring is the split casting method and welding method in Fan casting technology.
This is an advanced technology of the block method. At this time, the Central Plains had already had the block method.
The earthen kilns of the past were not powerful enough to heat copper and other metals to a liquid state, but Di Hong used his superb ancient wisdom to fully restore the traces left by Yu Zai.
Hence the birth of the current adobe workshop.
Use vitality and witchcraft to inject new earth kilns to simulate a stressful environment; combine several earth kilns to strengthen their sealing and durability, and dig out special vents to concentrate the pressure. A dozen people used sheepskin bags to blow air to ensure firepower.
There are also opinions on the choice of copper. To make weapons, you must choose bronze and brass. Red copper is soft and has a high melting point, so it is not suitable for casting weapons.
The Dihong family knew that the so-called combination of copper and tin could better melt and cast bronze. This knowledge existed in the era before Chi You, and Chi You, as the ancestor of the army, left too many basic smelting foundations to the people of this era. technology.
For example, "Learning to Cast Bronze in Three Days", "Three Years of Stonemasonry and Five Years of Coppersmithing", "Explanation of Fire Conditions", "Blast Furnace Manufacturing", "Ore Science Popularization", "How Bronze is Made"...
Di Hong's eyes were filled with light.
Just like the experience bar is constantly rising, technology is advancing through constant destruction and exploration.
If he can master this technology, he can quickly surpass the Central Plains in population and productivity!
"The people of the Akagata clan..."
Di Hong squinted his eyes and thought a lot.
"Even an escaped Akagata wizard can easily construct a simple smelted copper vessel. Although he is a fire wizard, it also shows that in the south, all kinds of crafts are prosperous."
Di Hong was tempted, but also regretted it. He would have moved to the south if he had known it, but now he had no way to turn back, which was an advantage for the Jinyun family.
"Wait, Zhongyuan, I will be back soon, bringing with me bronzes all over the mountains and plains!"
"I wonder if Taotie has captured the land in the south at this time?"
…
The time came not long ago.
In the south, on the edge of the river.
Taotie was already holding a big ax, leading a group of people, driving a group of small boats, and secretly crossed the East Tidal Flat with the help of the smelly herbal medicine made in Luwangdu.
Everything is going according to plan.
"Southerners would never have imagined that we would suddenly appear behind them."
The leaders smiled strangely, and soon they stopped laughing.
They saw a sign with a sheep's head in front of them, and the sheep looked particularly in need of a beating.
Taotie was surprised and suspicious.
Could it be a scam?
Did the southerners see through their clever scheme?
So he pointed to Huo Zheng of his tribe and asked him to take a look. Huo Zheng was immediately frightened and quickly said that there are so many leaders, why do you think so highly of me?
Taotie said that you are a fire fighter and should take the lead. I will marry your wife, so you can go ahead.
Huo Zheng left with hatred. When he reached the signboard, he saw the situation clearly and breathed a sigh of relief.
Seeing Huo Zheng letting everyone pass, Taotie nodded. After everyone passed, Huo Zheng pointed to the sign and said:
"This sign has been standing here for some time. It has been rotten by the wind and rain. It looks like it is at least 20 or 30 years old."
Twenty or thirty, that is, half a month?
Taotie thought about it for a while.
With the sign written so long ago, it's definitely not because they knew about their plan. After all, the other side couldn't predict the future, and what's written on it...
"The great lamb warns you that there is construction ahead, garbage cleaning, and traffic is prohibited...if you don't listen to dissuasion, you will be responsible for the consequences?"
