Wei Renshi took Li Chun away from the glass kiln, came down to the coal yard, and walked back along the road.

Go to the coal yard, enter the back mountain, continue walking along the road next to the foothills, turn over a sudden mountain and enter a valley.

Several armored soldiers wearing iron armor and holding weapons were firmly holding hands at the entrance of the valley.

"This is..." Although Li Chun was introduced by Li Shi and Li Song to test and improve the method of iron smelting and steel making, it was just a name. In fact, Wei Ren was actually doing it. Therefore, Li Chun never came here.

"Prince Chun must have heard of it. I have offered a set of methods to improve iron and steel smelting. Your Majesty and the Crown Prince asked Prince Chun to come in the name of the experiment." Wei Renshi said.

Li Chun nodded: "No, is it here?"

Wei Renshi nodded and replied, "It's here. Today, good steel is produced by the innovative method."

"Have you made good steel?" Li Chun's eyes lit up and he immediately asked, "What are the benefits compared to the past?"

This immediately came to the point.

Good steel can be made using the old methods of the past. If you change the method of making steel, it is naturally a special benefit to be considered improvement.

"Better quality, lower cost, more iron material saving, faster production." Wei Renshi replied: "Prince Chun, please stop!"

Everyone went to the valley, and when they approached, the soldiers hurried over to salute Li Chun.

Li Chun waved his hand and entered.

I saw several extremely high furnaces standing up in the valley. The furnace belly diameter was larger than the bottom diameter, and gradually contracted from the belly of the furnace to the top of the furnace, like a large drum standing up one by one.

In front of each furnace, there was another earthen wall built, like a small house, with fire burning underneath. There was another strange thing, and several people were holding it and pushing it and pulling it.

Several others were next to the furnace, smashing some red and white stones into the furnace from time to time.

"These stoves... are different from what I have seen before." Li Chun said as he looked at the stoves.

"This kind of furnace is durable and easy to gather fire and heat up." Wei Renshi explained: "The connected one is called a hot chamber. When burning it with fire, the air inside will become hot. Then, with a bellows - the one that pushes and pulls - the hot air in the hot chamber can be sent into the furnace, so that the fire in the furnace will be larger and will not lower the temperature due to the cooling of the air blown in."

"What is this kind of stone? Why do you need to be mixed in?" Li Chun asked again.

"This is fluorite. After adding it, the iron inside can melt faster." Wei Renshi smiled and said, "The things burned below are not ordinary wood charcoal, but the coke made from charcoal coke in the coal yard in front. It is hotter, more stable, and more resistant to burning."

While speaking, the blacksmiths who were making weapons in the shed behind had already discovered them, and the leading old blacksmith quickly came over.

This old blacksmith was found by Li Shi, and his skills are very outstanding.

"The head of Pang is on the stove, but it hasn't come down. Justice Wei, please come in first!" The old blacksmith said to Wei Renshi and the others.

Pangtou is another leading master, who is in charge of iron smelting and steelmaking.

"I heard that it's so good?" Wei Renshi asked.

The old blacksmith immediately looked full of joy and became excited, and quickly replied: "It's out! It's out! It's okay! A little bit of knocking is better than Bai Rui Steel! Please ask Mr. Wei!"

The old blacksmith led Wei Renshi and his men to the back, and went to a room guarded by the soldiers, and took out a locked long box.

When you open the long box, there is a horizontal knife inside. The style looks no different from an ordinary horizontal knife, but the gloss pattern feels different. When you look at the gloss pattern, you will know that it is not an ordinary product.

Li Chun was very novel and picked up the horizontal knife from the wooden box first, looked around for a long time, and then suddenly turned around and signaled to his servant.

His attendant hurried over and saw Li Chun take out a short blade from his waist and hand it over to the attendant.

The attendant took the short blade, pulled it out of the leather case, and then pushed the short blade horizontally, with the blade facing upwards.

Judging from the skillful appearance of this servant, it can be seen that Li Chun often tests the knife like this.

This short knife is not an ordinary product at first glance. Not only are there hand-carved patterns on it, but there are also clearly visible light and dark intertwined on the blade. The black knife body is bright as snow-like markings mixed in it, like a night sky full of stars.

Steel making hundreds!

Wei Renshi recognized the texture of Li Chun's short knife at a glance.

"Good knife!" Wei Renshi praised: "The best hundred steelmaking!"

When Li Chun heard Wei Renshi's words, he couldn't help but look back in surprise: "Brother Renshi also likes weapons? Otherwise, how could he recognize this unique Baijian Steel? Hahahaha, this is a good Baijian Steel Round Cake that Emperor Ye gave me back to me. I asked Aye to send the best blacksmith, which took half a year to create!"

"This knife is not an ordinary person." Wei Renshi nodded and said, "Haha, I guess Prince Chun tried to cut off many weapons with this short knife?"

Li Chun smiled faintly, but the pride in his eyes could not be concealed, and said, "This knife is so sharp that it is rare in the world. I dare not say that he can cut off all other swords and weapons, but so far, there are no weapons that he cannot cut."

Wei Renshi was very expectant and hurriedly urged: "Okay! Hurry, try it!"

"Okay, you guys have a look!" Li Chun smiled and tiptoed on his sword, with a strong sense of confidence in his eyes, and said to Wei Renshi: "My knife is extraordinary. If you encounter an ordinary sword, you will definitely be sure to be sure. However, in my opinion, this weapon is forged extremely well. This time, my short knife is probably going to cut this weapon."

Although he was humble, he was suspected of saying this on purpose. Because the pride expression in his eyes could not be concealed.

Wei Renshi was very much looking forward to the performance of this weapon made from new steel, so he took a step back, made room for Li Chun to test the knife.

He really wanted to see how the new steel made by the improved method of iron smelting and steelmaking will compare with the famous Baijing Steel in history.

Li Chun's servant walked to the opposite side of Li Chun, knelt down on one knee, and held the hilt tightly with both hands to support it.

Li Chun took a deep breath and raised the horizontal knife in his hand high.

"Ha!" Li Chun took a few long breaths, then suddenly shouted violently, and there seemed to be a thousand pounds of force in his hand, and the horizontal knife in his hand slashed heavily on the short blade.

His servant was not waiting for the blade to fall, but rose up with a loud noise, and slashed the short blade in his hand with force, facing the horizontal knife in Li Chun's hand.

There was only a dull metal sound that the two of them pushed away a few steps, which showed how strong they used.
