Become a feudal king from today

"Your Highness is so talented. There is such a skill in making iron in the world. I am impressed by this."

In the steaming heat, Wang Ying was sweating profusely and saluted Zhao Xu.

He was convinced, and the doubts in his heart disappeared.

Zhao Xu looked as usual. In the eyes of the ancients, this was indeed like magic, but to him it was just simple knowledge.

But this simple knowledge was precisely what was important to his fiefdom.

It is also his key to solving the fiefdom crisis.

Now the technical problems of large-scale iron-making have been solved.

The problem of large-scale steelmaking was naturally solved.

Next, he can use these fine steels to build his army into a steel division.

Thinking of this, he couldn't help but feel relieved.

At this time, Wang Ying suddenly knelt down.

Zhao Xu was stunned for a moment and asked: "Master Wang, what does this mean?"

Wang Ying wiped the stains on his face and spoke sincerely, "Your Highness, Wang Ying, a humble person, while talking with Your Highness, I was deeply impressed by Your Highness's talent and learning. I hope Your Highness will not give up and teach you."

"Teach you?" Zhao Xu smiled.

Wang Ying nodded, "I know in my heart that there is a great disparity between myself and His Highness, but my life's ambition is here, and I am willing to pay any price to get a glimpse of it."

He was born into a poor family, but seeing that there was no hope for his official career, he traveled around the world, collecting the world's skills and writing books in order to leave his name to future generations.

But after entering the Military Division and seeing King Yan's magical skills, he suddenly realized that he still knew too little.

So he knelt down to beg for help without any shame.

Zhao Xu helped Wang Ying up.

It must be the effect of carbon and limestone that he mentioned when making iron just now that shocked Wang Ying.

However, in order to seek knowledge, he would rather put down his dignity. This is exactly the person he is looking for.

Only such a person can acquire and apply the knowledge he brought with him from modern times.

"Master Wang, please call me. I will give you all my money." Zhao Xu said with a smile.

Wang Ying was overjoyed and said, "Thank you, Your Highness."

Pointing to the molten iron in the pool, he no longer deliberately showed off this time, but explained in detail: "The difference between iron and steel is only the amount of carbon in it. For example, the carbon in these ten thousand kilograms of iron weighs between two kilograms and two hundred kilograms." A pound of steel, this is steel..."

Zhao Xu tried his best to explain in a language that Wang Ying could understand.

Wang Ying nodded frequently.

By the time Zhao Xu finished speaking, he basically understood why there were these differences between iron and steel, and how to achieve the conversion between iron and steel.

"I didn't expect that a small iron smelting could contain such a profound truth." Wang Ying sighed, as if Zhao Xu had opened a skylight for him.

At the same time, he also understood the principles of King Yan’s iron-making method.

He even understood how to make steel in a graphite crucible.

It is nothing more than carburizing the wrought iron and turning the wrought iron into steel.

"There will be more complicated and difficult truths in the future. Are you still willing to learn them now?" Zhao Xu joked.

"Your Highness, I have nothing to look forward to for the rest of my life. I only wish to listen to the teachings of Your Highness." Wang Ying said firmly.

Zhao Xu nodded slightly, "The iron-making method has been completed. Next, you will build twenty blast furnaces and make iron day and night. In the past few days, you will search for graphite and build crucibles to make steel."

"Yes, Your Highness." Wang Ying bowed and saluted.

Looking at the molten iron in the pool again, Zhao Xu was in a good mood.

This is the first step in the long march of Yan County's industry.

Come out of the Military Division.

He was about to return to the palace when he suddenly saw a puff of smoke and dust billowing from the north side of the main road in Yan County.

Dozens of cavalrymen galloped towards the palace.

Zhao Xu gave Xu Lie a look.

Xu Lie immediately put his horse in the middle of the road, blocking the cavalry's path.

As the cavalry approached, they all stopped when they saw Xu Lie, and noticed that King Yan was also here.

One of the cavalrymen jumped off his horse, walked quickly to kneel down in front of Zhao Xu, and cried sadly, "Your Highness, General Chang is seriously injured and is dying. I hope your Highness can save his life."

Zhao Xu and Xu Lie were surprised when they heard this.

"Where is General Chang?"

"Right there." The soldier pointed to the back of the team.

Zhao Xu passed the soldiers and saw a sedan pulled by two horses behind him.

Opening the sedan curtain, Chang Wei was lying inside, his body covered in blood, and three short arrows were still deep into his flesh.

"Immediately carry General Chang to the palace to rest." Zhao Xu ordered.

There was no time to ask what happened at this point.

After receiving the order, the soldiers immediately led Chang Wei to the palace.

Xu Lie was shaking with anger, gritted his teeth and said, "People from Beidi..."

"Go back to the palace first." Zhao Xu glanced at him and rode towards the palace, followed by Xu Lie.

Return to the palace.

Zhao Xu asked Feng'er to choose a yard for Chang Wei, sent two maids to take care of it, and called the doctor, and then asked the soldiers why.

"Didn't I say so? You act according to the circumstances. Why is General Chang still so seriously injured?"

A soldier said sadly: "Originally, we were just watching the Beidi cavalry, looking for opportunities to annihilate the enemy."

"But the Beidi cavalry were too cruel. After discovering us, they entered a village and drove the people in the village to the ridges to behead them in turn, forcing us to fight."

"General Chang couldn't bear the casualties of the people, so he ordered us to come forward to fight. However, we were ambushed by the Beidi cavalry and were attacked from two sides. The Beidi cavalry's arrow skills were accurate. Although we fought to the death and wiped out most of the enemy, we suffered heavy losses and the general was also seriously injured. ”

The soldier spoke truthfully.

"Hey!" Liu Fu also came over from the concierge and sighed after hearing this.

Before Chang Wei left, he said this specifically.

But he still suffered such heavy losses.

Zhao Xu's face was ashen.

He didn't blame Chang Wei. If he encountered him, he would not be able to help but take action, even if he died in battle.

"Are you the only ones back?" Zhao Xu asked.

Five hundred cavalry went out, but only a few dozen came back, which would have been too heavy a loss.

"We are just going back first, there are more than a hundred people behind us," the soldier said.

"Half." Zhao Xu muttered.

Not bad. The level of these cavalrymen varies greatly.

It was not easy to have half the survival rate under the elite Beidi scouts and to defeat the Beidi cavalry.

He had no one to blame.

At this time, the doctor came over, and Zhao Xu ordered him to diagnose and treat Chang Wei.

Rolling Chang Wei's eyelids, the doctor untied Chang Wei's clothes.

Under the blood stains, three arrows penetrated deeply into Chang Wei's body.

One on the shoulder, one on the arm, and one on the back.

Because of the hot weather, these wounds were red and rotten.

Zhao Xu frowned more and more.

Obviously, Chang Wei lost too much blood and became comatose due to wound inflammation.

He raised his hand and tried Chang Wei's head, which was hot.

I secretly thought it was terrible.

The doctor said at this time: "The general lost blood and was weak. These wounds have aggravated the injury. It's just a matter of mending the deficiency, but these arrow wounds may kill the general."

He has treated many wounded soldiers, but whether the soldiers with deep, red and swollen wounds can survive depends solely on fate.

Xu Lie and the other soldiers' eyes were red. They had been soldiers for many years, so they naturally understood that the doctor was not talking nonsense.

Zhao Xu also felt heavy.

If he loses Changwei, he will lose an arm.

But in ancient times, many more soldiers died from wound infections than died in direct combat.

Unless antibiotics are available.

"Antibiotics?" Something flashed in Zhao Xu's mind.

Chang Wei's current situation is very serious, and he cannot leave his life and death to God's decision.

Now, he can only give it a try. Of course, he is not willing to come up with things like penicillin.

But there is one thing that has similar results.
