Back in the Western Capital, Du Pre came with a drawing.

It is a flow chart of iron smelting.

The conversion methods of pig iron, wrought iron, and steel are marked above.

Different from the previous block refining method, the pig iron is first connected to mature iron, and then the wrought iron is smelted into steel.

Rather, it is mixed smelting of pig iron and wrought iron.

"This method exists at the end of the Han Dynasty, called the steel filling method, there are blacksmiths in Guanzhong smelting by this method, I sorted out the iron smelting technique in the Guo family's collection, visited the blacksmiths in the western capital, and figured it out, but it is not mature, how much pig iron and wrought iron contain, and the fire temperature of smelting may increase."

In this era, there is a steel filling method?

Yang Zheng was ecstatic.

Technology is combat effectiveness.

Later generations always said that the four major inventions, but the steel filling method was omitted, in fact, the highest gold content should be the steel filling method.

Yang Zheng remembered that when it was the Northern and Southern Dynasties, a name called Qi Wuhuaiwen was improved.

At first, I remembered it because the name was so weird.

The traditional block refining method, as if forging, infiltrates carbon into wrought iron and smelts it into steel.

In the steel filling method, pig iron and wrought iron are mixed and smelted according to a certain ratio.

Wrought iron takes the carbon in pig iron into steel, and pig iron is decarburized and directly formed into steel at high temperature.

This technique did not appear in the West until the seventeenth century.

The cattle of this era are all-round.

It's okay to be immature, Yang Zheng, as a traverser, knows that this path is right.

The rest is experimentation.

"Yuan Kai's method can be worth 100,000 troops!"

Du was happy beforehand, but in an instant, his eyebrows and eyes were full of worry.

"With this steel filling method, Dawei is also lucky!"

Of course Yang Zheng understands this, "This is also a blessing for Huaxia!" ”

The two generations of the Du family were protected by Wei En, and Du Pre was protected by Xiahou Xuan, although Cao Shuang and Sima Yi did not want to see the Du family, but it did not prevent Du Pre from being loyal to Cao Wei.

However, Yang Zheng feels that many technologies are invented by people from families, but they are also inseparable from the continuous practice and improvement of the people in their work.

From the end of the Han Dynasty to the Wei and Jin dynasties, it can be called an era of technological explosion.

Zuo Bo paper, steel filling method, hemp boiling powder, pi, gunpowder, nine chapters of arithmetic, Qi Min to art, typhoid theory, etc.

Regardless of fatigue, Yang Zheng and Du Yu hurriedly entered the blacksmith shop in the city.

The blacksmith in the city was originally Guo's domestic slave, and together with carpenters, leather smiths and other technicians, they were all occupied by Yang Zheng.

This is the first pot of gold for real life.

Relying on Yang Zheng to grope in Caohan, after all, it was a small fight, and I didn't know that I had gotten the Year of the Monkey.

The mixed ratio test of pig iron and wrought iron came out after a few times.

The biggest problem with the steel filling method is the temperature.

That is, the fineness of the charcoal.

Eat the rice one bite at a time, and the road is one step at a time.

This winter, Yang Zheng and Du Yu almost stayed in the blacksmith shop, improving step by step, from the forge, to the luke, to the charcoal.

I've never eaten pork, but I've seen pigs run.

Yang Zheng knew the general idea, and often two or three sentences made Du Premao pause.

And Du Pre is meticulous, can understand one point, and his hands-on ability is extremely strong.

The two of them worked together to learn from each other's strengths, and spent twenty days and nights in the blacksmith's workshop, unkempt, sleeping by the forge when they were tired, and eating a mouthful of dry food when they were hungry.

There is nothing difficult in the world, only afraid of those who have a heart.

After more than 20 days of contact, Yang Zheng found that Du Yu was the top skilled craftsman in this era.

Something in his hands, it takes an hour or two to transform it more reasonably.

In addition to coming up with some ideas, Yang Zheng spent more time helping him.

The resources of the entire western capital city were mobilized, and a piece of steel was finally trained by the steel filling method.

Du Yu, who has always been calm, couldn't help but smile.

"Xingyun, this steel crown is the best in the world!"

Not only is it the best in the world, but it is also extremely efficient, and it does not need to be tempered as much as before.

Of course, it is indeed easy to produce high-quality products after a lot of tempering.

Wei Wu once forged a hundred sword and a sword in the sky, decorated with dragons, tigers, bears, birds, and birds, and transferred 70 top skilled craftsmen, which took five years to succeed.

But it's not really suitable for use on the battlefield.

It is even more impossible to equip on a large scale.

"If you get this miracle, you will break Zhongqiang!" Yang Zheng said with a smile.

Dealing with Zhong Qiang is actually overkill, this thing is ahead of this era.

Cold Forging Armor, Iron Float Chart, and Kidnapping Horse can be introduced in advance.

The two looked at each other and laughed in the blacksmith's workshop.

"This law is my treasure in China, and it must not be disclosed, and I will set up a waiting official to supervise it." Yang Zheng advised.

Du Zhen thought so.

Yang Zheng returned the connected steel to the furnace for reforging, and made a 20-pound long-handled mace with the cooperation of Du Pre.

In the Spring and Autumn Period and the Warring States Period, there was such a weapon, called "殳".

Call Liu Heng and let him try.

"Why is this thing so ugly?" Liu Heng looked disgusted.

Du Yu laughed again.

Yang Zheng couldn't wait to spray a mouthful of old blood on his face, this guy looked like a crooked melon and cracked dates, but he was disgusted.

Every time he goes to the battlefield, it is this guy who destroys the most weapons.

"Less nonsense, you try your hand." Yang Zheng didn't bother to explain.

Liu Heng reluctantly mentioned it and weighed it twice, "It's okay." ”

Dance, tiger and tiger.

When a stick goes down, the stones shatter and the ice and snow fly.

Liu Heng quickly sensed the vigor of this thing, and couldn't put it down, "Why didn't the general take it out earlier?" With this thing in hand, Meng Yu is no match for me! ”

"Don't you think it's ugly?" Yang Zheng didn't have a good airway.

Liu Heng touched the back of his head, "My subordinates don't know the goods, don't blame the general." ”

The two laughed and scolded, and the guards rushed over, "General, Zhong Qiang's envoy asks to see." ”

"Let him come here and see so-and-so."

"Obey."

After a while, Zhong Qiang's envoy was brought, or Ke Gu, who was a little surprised to see Yang Zheng's unkempt appearance, but those who can be envoys must have flexible heads, and quickly controlled their eyes, "Ke Gu meets General Yang." ”

"Why did you come here?" As soon as this person came, Yang Zheng knew what to do.

"Since the general promised to send troops, why didn't he see any movement for a long time? Qin Hu and Lu Shuihu are less than 200 miles away from the general, and they can be destroyed in ten days. ”

"Are you here to teach Ben how to do things?" Yang Zheng's eyes sank, and his tone was very unkind.

"Don't dare, don't dare, since the general has formed an alliance with the king of my family, as allies, they should help each other." Ke Gu's eyes flickered a few times.

"Ye Wu cruelty Xiping, the people's grain is taken by them, our food and armament are insufficient, now the cold ground is freezing, Qin Hu, Lu Shuihu has always been cunning, there is a land in hand, hastily dispatched troops, is not self-defeating? If your king really cares about the love of his allies, why don't you support some grain, cattle and sheep to help Ben tide over the difficulties? Yang Zheng's words are half true and half false.

Ke Gu thought for a while and said: "Since the general has difficulties, he will give the king Ming Ming in the next meeting and ask for food for the general, but I don't know when the general will send troops, set a date, and take the heart of the king of my family." ”

Seeing that his appearance seemed to be a little serious, Yang Zheng seemed to smile and said: "The day your family's grain arrives is the time when Ben will send troops." ”

Ke Gu clenched his fist on his left chest and made a Qiang salute, "At that time, I hope that the general will keep his promise." ”

"You kept your promises, and Ben will certainly keep them."

After Ke Gu left, Du pretended: "Midang has always been greedy and cunning, and now he tempts me with profit, and he must have other plans." ”

"We must be preparing to attack the West Sea again, and stabilize us first." Yang Zheng is a fan, and he has met a few times, and he knows a lot about this person.

"If the fan really sent food, could it be that we really want to fight Qin Hu?" Liu Heng interjected.

"Why do you want to fight? Isn't it okay to fake a fight? When the time comes, just send troops to deal with it, and the general has never said that he must exterminate Qin Hu. ”

"The subordinates feel that Zhong Qiang may not be able to send food, and in a few days, Zhong Qiang may have movement."

"Then let Meng Guan prepare earlier."

However, until the wind and snow melted, the fan didn't do anything.

During this period, Meng Guan led 500 Qiang soldiers and Shao Tiyan and 1,000 Hu people into the West Sea and defected to the captives.

After being defeated by the Han army, one of them was exiled to the Xihai grassland, and merged with the local Yueshi and Ding Ling Zhuqianghu.

In Xihai, it is not a big force, and when Yang Zheng broke his hometown, Tuotu, the leader of the captives, also visited Yang Zheng.

Winter goes to spring, and the first eight years are rolling in.

There is not even a shadow of the food in the past.

The ice and snow are just showing signs of melting, and the Huangshui River Valley has just thawed.

The entire Xiping County was busy, and Yang Zheng issued a reclamation order.

Both military and civilian slaves, all go into battle.

Aqueducts were opened, and dock forts were built.

In troubled times, only food retains its value the most.

Food is also the foundation of everything.

At the end of the Han Dynasty, a large number of people were confined by the nobles, and the people who lost their land took the initiative to become slaves, wasn't it also because of the grain in their hands?

In order to improve efficiency, Yang Zheng also built a lot of iron farm tools, and ploughing cattle and horses were also distributed to various dock forts.

Everything is ready to go.

During this period, Meng Yu also brought other Qin Hu leaders to visit.

Yang Zheng was not stingy and sent some leather armor and food.

Under the leadership of Jiang Faye, Lu Shuihu and Qiang also gradually moved closer to Yang Zheng.

Many small tribes simply entered the western capital and became the rulers.

Yang Zheng naturally did not refuse.

Han and Qiang are homologous, and they are all developed from the northwest region.

One went east along the Yellow River and merged with the Yandi Shennong tribe, and the other went west against the Yellow River and became the Qiang people.

It's almost March, the snow and ice are melting, and the cold wind is not subsiding.

The bewitched messenger Ke Gu came again, and Yang Zheng was annoyed.

It's boring to do it every day, thunder and no rain.

However, in order to stabilize Zhong Qiang, Yang Zheng still met.

"My king will attack the West Sea in March, is the general willing to send troops together?" Ke Gu didn't seem to remember the promise he made more than a month ago.

He didn't mention it, Yang Zheng didn't mention it, everyone tacitly did.

"General Ben sent troops, how will it be counted at that time?"

Soldiers, in line with the interests of the move, not in line with the interests of the stop.

In a word, if you don't see a rabbit, you don't scatter an eagle.

Ke Gu's eyes rolled, "At that time, Long Qi will return to the general in the east and the king in the west." ”

Yang Zheng almost didn't laugh out loud.

Longqi is just north of Linqiang.

The west of Longqi was originally the territory of Xiping County, but now it is occupied by Lu Shuihu.

And Lu Shuihu didn't have much hostility towards Yang Zheng.

So Yang Zheng didn't use a knife against them for the time being.

This is the white prostitute of Chiguoguo.

Is there such a shameless person in the world?

"The king is really fair, so it is decided, and when the time comes, he will lead an army of 30,000 to help your king sweep the West Sea." Yang Zheng opened his mouth and came.

The fan can be dropped once in the West Sea pit, and then it can be dropped a second time.

Moreover, Yang Zheng and the ambush soldiers sent by Meng Guan and Shao Tiyan will be enough to drink a pot of confusion when the time comes.

Ke Jian laughed, "The general really values love and righteousness. ”
