Three Kingdoms

Huang Chengyan looked at Fei Qian, who suddenly looked stupid, shook his head, smiled again, and then walked quietly to the side without disturbing him, and also made a gesture to the craftsmen around him to let people know. Stay away, don't disturb Fei Qian's thoughts...

This son-in-law is good at everything, he has a gentle temperament and is courteous to others. He is familiar with scriptures and is a direct disciple of the two major literary leaders in the north and the south. He also has no objection to the craftsmanship of the Mohist family and has some amazing ideas and innovations. Now he is even more young. He has easily become a member of the ranks of two thousand stone officials. His scepter has real power, he can command troops and horses, and he has good strategies...

Huang Chengyan clicked his tongue softly. Fortunately, I was quick to act. Hehe, otherwise I would just be drooling and greedy now. But this son-in-law is good at everything, but there is one thing that is not so good!

Huang Chengyan couldn't help but sigh.

Suddenly, Huang Chengyan felt his sleeves being pulled, and an extremely familiar voice sounded beside him: "Father...then...what are you thinking about?"

"Why isn't his surname Huang?" Huang Chengyan was regretting in his heart, but when Huang Yueying pulled him like this, he blurted out instantly.

Huang Yueying was stunned for a moment, and then she understood. She tugged on Huang Chengyan's clothes again angrily, and repeated: "Father! I'm not asking what you are thinking! I am asking... what Fei Lang is thinking. …”

Huang Chengyan said "Ah!", and some of his old faces turned red. He had to pretend to be as if nothing had happened. While straightening the clothes that were a little crooked by Huang Yueying's pulling, he said: "Don't pull, don't pull, it's all crooked. I I know there...probably how to improve the craftsmanship of crossbows..."

"Improve the craftsmanship of the crossbow?" Huang Yueying asked with her eyes wide open, "Isn't the craftsmanship of the crossbow quite complete now? Why do we need to change it?"

Huang Chengyan coughed twice and said seriously: "You don't understand this. Nowadays, no one uses crossbows. One is expensive and the other is slow. Now your Fei Langjun can't turn back on this expensive road." Now, we can only try our best to make this expensive one faster and more powerful... Well, no wonder the surname is Fei..."

"Huh?" Huang Yueying blinked, not knowing why.

Huang Chengyan coughed twice again. He was joking about the junior's name. He thought it was okay, but if he told it, he would be considered disrespectful, so he kept silent.

"But...but, the preserved pork is ready..." Huang Yueying said.

Huang Chengyan looked at Fei Qian, who was still immersed in thinking, pondered for a moment, then turned and left, saying, "Just leave your husband Fei Qian here alone, let's go eat first..." Huang Chengyan said before He often does this too. He forgets to eat and sleep when thinking about a problem. It is also common to work from dawn to dusk in order to solve a problem with a device. So he also knows that what Fei Qian hates most now is to have his thoughts interrupted, so he is very worried. He carelessly left Fei Qian alone, flicked his sleeves, and decided to go eat first.

"..." Huang Yueying stood blankly, not knowing how to talk about it. The evening breasts had a soup she made by herself...

Huang Chengyan walked a few steps and suddenly realized that Huang Yueying had not followed him. He turned around and saw Huang Yueying staring blankly at Fei Qian. He subconsciously smacked his lips, and suddenly there was a feeling in his heart that he didn't know how to describe...

"Yueying, let's go. If it doesn't work, let the chef warm him up..." Huang Chengyan said, then turned and left, muttering in a low voice, "Humph... He won't starve to death even if he eats less..." …”

"...Oh, okay..." Huang Yueying looked at Fei Qian again reluctantly, then quickly followed Huang Chengyan and said, "Father, what did you just say?"

Huang Chengyan was startled and said seriously: "I didn't say anything... It's time for dinner, dinner. Is there anything delicious in the evening?"

Huang Yueying jumped for joy, smiled like a flower, and said: "There is a soup I made tonight!"

Huang Chengyan said: "Then I want to have a good taste... Oh, no wonder you came to ask me to eat in person. I'm afraid you didn't come to ask me, but..."

Huang Yueying's ears felt hot, and she quickly lowered her head and hugged one of Huang Chengyan's arms and shook it, "Ah! Father, if you say this, I...I won't do it next time..."

"That's not okay. If I eat one meal, I will lose one meal," Huang Chengyan suddenly said harshly, "I won't eat any other dishes later. I'll finish the soup made by Yueying first!"

"Ah! Father!" Huang Yueying lowered her head and glanced at Fei Qian quickly, then pushed Huang Chengyan's back forward.

Fei Qian didn't notice the actions of Huang Chengyan and Huang Yueying at all. His mind was really in a mess now, with all kinds of information and methods pouring in...

The gap of thousands of years is no joke. Many things are related to each other, just like a bucket. If one piece is missing, the whole thing is useless.

The requirements for the industry of later generations are really too high. It cannot be summarized by an ordinary assembly line. It must have workers who are separated from agriculture and animal husbandry, and have related supporting machinery, raw materials, etc. But now, Fei Qian does not want to turn all the industries of later generations into I moved them all here, just to complete the material improvement of the crossbow weapon project under limited conditions.

Drawing machine!

Fei Qian had already thought of several different plans, but due to the constraints of the Han Dynasty, there was no way to complete them, such as hot rolling and cold rolling...

The Han Dynasty already had some technologies that were absolutely ahead of the rest of the world in the field of steel casting based on the work of its predecessors. Almost every household used farm tools, including plowshares, columbians, plows, rakes, rakes, sickles, etc. , almost a complete set of tools from tillage to harvest is available. Daily necessities made of steel such as lamps, cauldrons, furnaces, scissors, knives, etc.; weapons such as swords, halberds, spears, shields, knives, axes, arrowheads, etc., and even ductile iron and single-hole small-mouth stack casting technology appeared.

In the Western Han Dynasty, the method of increasing the temperature in the furnace changed from manpower to oxen and horse power, and the cow wind row and horse wind row appeared. In the Eastern Han Dynasty, craftsmen also invented the use of water power to drive wooden wheels to drive rows of skin drums. Wind, water, wind, and various technologies mean that the basic conditions for steel have already been achieved in the Han Dynasty. Now it is only through various technological means that the Han Dynasty steel industry, which is now ahead of the entire world, will be further developed. Just push it to a higher stage!

Fei Qian took a wooden stick and scratched it on the ground. Each link was drawn, and each process was listed. He inspected it and kept circling it in his head, trying to integrate these processes to achieve the final result. The effect he wanted...

After pig iron is annealed at high temperature, a high-strength malleable cast iron (called malleable cast iron) can be obtained. The West only understood this technology after 1722, while China mastered this technology more than 2,000 years ago during the Eastern Zhou Dynasty. The iron woks unearthed from the Han Dynasty iron smelting site in Tieshenggou, Henan, and the iron axes from the Han and Wei dynasties unearthed in Mianchi, Henan, were tested by the Center Laboratory of Metal Materials Department of Beijing Iron and Steel Institute and proved to contain very good spherical graphite...

In 1974, a 50-year-old steel-making sword was unearthed in Cangshan, Shandong Province in the sixth year of the Yongchu period of the Eastern Han Dynasty (AD 112). Steel parts made from fried steel. This is the advanced stage of steelmaking...

A Han Dynasty mold kiln was excavated in Nanwen County. In the rectangular kiln of about nine square meters, more than 500 sets of stacked molds were found. This is a fine casting process...
