Luoyang, Jinwu Lane, Cao Mansion.

The stove forged weapons burned for a whole day, and even though it was far away from the stove, you could feel the heat here.

Liu Sandao was making steel, sweating profusely.

Just a day ago, he didn't even know what steel was. Cao Shuo's analysis was very simple. The one who could cut iron like mud was the one who refines fine steel.

As for how to refine refined steel, Cao Shu couldn't tell me why!

However, after hearing the "steel filling method" theory proposed by the young master Cao Shuo, Liu Sandao seemed to have opened the door to a new world and decided to give it a try without hesitation.

Logically speaking, steel does not belong to this era, and its earliest appearance was in Northern Qi more than three hundred years later.

However, after thousands of years of development, this technology continues to shine and heat in the 21st century.

Even Cao Shuo's hometown has a famous steelmaking enterprise, and several of Cao Shuo's uncles are still working as technicians.

I have never eaten pork, and I have always seen pigs run away.

Under the slightestness, Cao Shu also wrote down the steps for forging steel.

In fact, the principle is very simple, which is to melt pig iron and act as a carburizing agent to quickly carburize into the cracked iron.

Crafted iron becomes steel due to the infiltration of carbon, and pig iron can also become steel due to decarbonization...

After all, I have experienced nine years of compulsory education.

Cao Shuo can recall some of the principles. At high temperatures, the carbon, silicon, manganese and other elements in liquid pig iron will react with the oxides in the cracked iron, so that impurities can be removed, metal structure can be purified, metal quality can be improved, and metal quality can be improved, and the so-called steel can be refined!

Of course, theory is theory.

After practical operation, there are still many problems.

For example, for steel with different carbon content, what is the ratio of pig iron to cracked iron? What proportion of steel? Can iron be cut like mud? What proportion of steel is the legendary refined steel? And steelmaking does not seem to require coal...

One by one, the other questions filled Cao Shu's forehead with question marks.

Even for a moment, he regretted not memorizing the chemical element table well...

Fortunately, Liu Sandao is very persistent and professional!

He kept trying various proportions of pig iron and cooked iron, and tried it at different temperatures. He had to eat lunch all day long.

Every time, Liu Sandao was ecstatic whenever he could feel the hardening of the steel increased a little.

Of course, his countless attempts were based on the huge consumption of iron.

The best titanium is a sky-high price in this world. If the Cao family had no background, they would definitely not be able to withstand Liu Sandao's attempts.

"Brother Shuo, the steel made from these irons seems to be harder than the original irons. I think the weapons forged will definitely be sharper? Why does Uncle Sandao still persist in trying it?"

Cao Ang has also looked at it for a long time...

While surprised that iron turned into steel, he also admired Liu Sandao's perseverance.

"This is pursuit!" Cao Shu slapped his mouth and pinched his waist. "If he didn't make the steel that satisfies him, Uncle Sandao would probably not give up!"

Cao Shuo thought well.

Liu Sandao practiced forging since childhood. His childhood dream was to create a peerless artifact. It was like when we were young, our dream was to be a scientist.

It was originally an endless thing, but suddenly, Cao Shu opened the door to a new world for him, and the dream of forging a magical weapon seemed to be realized.

Who would have been? He would have tried this with no effort and forgot to do it...

"Bang, bang, bang..."

The sound of forging is endless...

Cao Shu was already sweating profusely. Liu Sandao approached the melting iron furnace. It was obvious that he was hotter, but even so, he did not take a step back for the whole day!

"Brother Cao Ang, let's go!" Cao Shu nodded gently and immediately greeted Cao Ang.

"Ah? I won't wait for Uncle Sandao!"

"I won't wait, he will probably take a few days!" Cao Shuo smiled slightly and immediately ordered Acai. "Uncle Acai, Uncle Sandao's food, I will send someone to the melting iron stove... By the way, add more meat and prepare more water to deliver it from time to time. It's too hot here."

"Don't worry, little boy!" A Cai agreed...

Cao Shu looked at Liu Sandao again, and then left with Cao Ang.

Speaking of which, it’s time to prepare a small schoolbag, and the school will start in two days.

Hey.

But at this moment, Cao Shu noticed that water droplets fell from the sky...

"March? Is it raining?" Cao Shu murmured in his heart. "March of Guanghe for the fourth year? It's terrible. The Yellow River in Dunqiu County is afraid that it will burst the dam!"

Suddenly, Cao Shu became nervous!

...

...

Luoyang, the Imperial Palace, Deyang Palace.

"If you fight against the Xianbei Huqi, you will be General Huangpu."

The troops were ready and everyone was looking for it. Emperor Liu Hong personally appointed Huang Pusong as the general to fight the enemy.

The rich emperor Liu Hong, under the reminder of Cao Shu, had some higher spiritual needs, such as the determination and will to fight the Huns in the north, which had already awakened.

"I will definitely live up to Your Majesty's instructions."

Huangpu Song bowed and said that he was the descendant of the general, his ancestors and fathers once made a great reputation in the war against the Hu people. Now, the baton is handed over to him. This is an opportunity to become famous all over the world and a chance to regain the might of the Han Dynasty. He knows it is of great significance.

"I don't want to say anything more. The lessons I learned five years ago were heavy. General Huangpu must win this battle!"

Emperor Liu Hong said slowly...

The lesson he taught was that in April of the sixth year of Xiping, more than 100,000 troops led by Xia Yu to conquer the Xianbei, but they were defeated and destroyed by the Hu people in the Xianbei situation, with a sad scene.

Now that I think about it, You Zi is vivid in my mind. It is this great defeat that completely wiped out the pride of the Han people and the confidence of Emperor Liu Hong.

It's ironic to say...

This time, Emperor Liu Hong made up his original intention to conquer the Xianbei, but not to find the military spirit of the Han Dynasty, but to repay the favor of the little guy Cao Shuo.

"Your Majesty, I have only one request!"

"speak."

"The ministers who conquer the Xianbei are personally selected."

Huang Pusong's tone was serious.

He is a general, and he has always been very sensitive to the war. He knows that five years ago, the place where the Han army was defeated by 100,000?

It was because the court appointed children of clans in the army to try to make contributions on the battlefield. To put it bluntly, it was gold-plated to facilitate their promotion to higher positions when they returned.

The main general Xia Yu had no talent to use, and he could not support him alone. He was defeated by Yanmen and made the Xianbei arrogant for a full five years.

The past is unbearable to look back on, Huangpusong made up his mind that this time he would not use the sons of the aristocratic family and would have to select talents.

I originally thought.

This is not an excessive request, Your Majesty will definitely agree without thinking.

Haven't thought about it...

"No!" Emperor Liu Hong refused immediately.

"Your Majesty..." Huang Pusong wanted to persuade him.

"I can follow you all the rest, but there is someone who must appoint him as the cavalry commander! Let him make contributions in battle." Emperor Liu Hong proposed...

"I wonder who your Majesty is mentioning?" Huang Pusong was puzzled, and a bad premonition rose in his heart.

"Cao Cao!" Emperor Liu Hong directly read Cao Cao's name.

"But the eldest son of the Grand Secretary Cao Song family, Dunqiu Ling Cao Cao?" Huang Pusong asked back.

"That's right." Emperor Liu Hong nodded.

"Yes...but he has never been to the battlefield." Huang Pusong was afraid of this, so he reminded repeatedly. "The cavalry captain has to command thousands of cavalry to kill the enemy. Cao Cao? He is a young man with no battlefield experience? He is incompetent!"

"I can't be competent?" Emperor Liu Hong narrowed his eyes. "If you can't be competent, you can find a way to help him! His son has helped me a lot. The emperor's favor must be paid back! General Huangpu understands what I mean?"

"This..." Huang Pusong was silent...

He had heard that the Cao family's young grandson helped the emperor do business, causing the money in Wanjin Hall to overflow. For this reason, he only received 100 million military spending and more than 10,000 war horses in exchange for it. Lu Zhi also told him that it was also the credit of Cao Shuo, the young grandson of the Cao family!

Huh... Huangpu Song exhaled, he couldn't refute the emperor. While the emperor owed Cao Shuo a favor, did they all be generals? Don't they also owe Cao Shuo a favor?

It is still a good deal for them to change the appointment of a favor to the other cavalry captain.

"I understand..." Huang Pusong bowed and accepted the fact that Cao Cao was appointed as the cavalry commander.

However, he had some opinions about Cao Cao, a guy who had no ability and had his son to take power? He looked down on him!
