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

Past the coal yard, enter the back mountain, continue to walk along the road next to the foothills, turn around a sudden mountain, and enter a valley.

A few armorers wearing iron armor and holding weapons in their hands firmly held the entrance to the valley.

"This is ......" Although Li Chun was pushed out by Li Shi and Li Yu to be the person who tested and improved the method of iron smelting and steelmaking, it was only in name. In fact, Wei Ren really did it. Therefore, Li Chun has never been here.

"Prince Chun should have heard of it. The minister presented a set of methods for improving iron smelting and steelmaking, and His Majesty and His Royal Highness the Crown Prince asked Prince Chun to preside over the test of this method in name. Wei Renshi said.

Li Chun nodded: "Yes, isn't this here?" ”

Wei Renshi nodded and replied, "Exactly here." Today, with the innovative method out of good steel. ”

"Good steel?" Li Chun's eyes lit up, and he immediately asked, "What are the benefits compared to the past?" ”

This was immediately to the point.

Good steel can also be made using the old method before, and if you change the method of steelmaking, it is naturally especially beneficial to be considered an improvement.

"Better quality, lower cost, more saving iron, and faster production." Wei Renshi replied: "Lord Chun, please! ”

Everyone went to the valley, and when they got closer, those armor soldiers hurriedly came over and saluted Li Chun.

Li Chun waved his hand and entered it.

I saw several extremely high furnaces erected in the valley, and the diameter of the belly of the furnace was larger than the bottom diameter, and it gradually shrank from the belly of the furnace to the top of the furnace, like a big drum erected one by one.

In front of each furnace, there was another earthen wall, like a hut, and a fire was burned underneath. There was another strange thing in a row, and several people were holding and pushing and pulling.

A few others were by the stove, and from time to time some red and white stones were smashed into the furnace.

"These stoves...... It's not like anything I've seen before. Li Chun looked at the furnaces and said.

"It's durable, and it's easy to heat up." Wei Renshi explained: "The one connected is called a hot room, and if you burn it underneath with fire, the air inside will become hot. Then use the bellows - that is, the one that pushes and pulls - and can send the hot air in the hot chamber into the furnace between pushing and pulling, so that the fire in the furnace is larger, and the temperature will not be lowered due to the cold air blown in. ”

"What is this pebble? Why do you want to redeem it? Li Chun asked again.

"This is fluorite, and when you add it, it can make the iron in it melt faster." Wei Renshi said with a smile: "The thing burned below is not ordinary wood charcoal, but coke made from the coal yard in front of it, which is hotter, more stable, and more resistant to burning." ”

As they spoke, the blacksmiths who were making weapons in the shed behind them had already discovered them, and the old blacksmith in the lead hurriedly greeted them.

This old blacksmith is the person Li Shi is looking for, and his skills are very superb.

"Pang Tou is on the stove, he didn't come down, Lord Wei, a few nobles, please go inside first!" The old blacksmith said to Wei Renshi and a few people.

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

"I've heard good steel?" Wei Renshi asked.

The old blacksmith was immediately overjoyed, excited, and hurriedly replied, "Out!" It's out! Okay! A little knocking and knocking, it's not worse than 100 steelmaking! Lord Wei, please! ”

The old blacksmith led Wei Renshi and the others to the back, to a room guarded by a sergeant, and took out a long locked box.

Open the long box, inside is a horizontal knife, the style looks no different from the ordinary horizontal knife, but the gloss texture is different, a look at the gloss pattern, you know that it is not ordinary.

Li Chun was very curious, and picked up the horizontal knife from the wooden box first, looked at it over and over for a long time, and then suddenly turned back and signaled to his attendant.

His attendant hurriedly came over, only to see Li Chun take out a short blade from his waist and hand it to the attendant.

The squire took the short blade, pulled it out of its holster, and then held it horizontally, the blade pointing upwards towards the sky.

Looking at the skillful appearance of this attendant, it can be seen that Li Chun often tries the knife like this.

This short knife is not ordinary at first glance, there is not only a look at the hand-carved ornamentation, the knife body is clearly visible light and dark interweaving, the black knife body, bright as snow markings are mixed in, as if the night sky is full of stars.

100 steel!

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

"Good knives!" Wei Renshi praised loudly: "The best 100 steels!" ”

When Li Chun heard Wei Renshi's words, he couldn't help but look back in surprise: "Brother Renshi also loves weapons?" Otherwise, how can you recognize this superb 100 steel at a glance? Hahahaha, this is still a piece of hundreds of steel round cakes that the emperor rewarded me at the beginning, and I sent the best blacksmith to Toaya, and it took half a year to make it! ”

"This knife is not ordinary." Wei Renshi nodded and said, "Hehe, presumably Prince Chun used this short knife to try and break a lot of weapons?" ”

Li Chun smiled faintly, but the pride in his eyes couldn't be hidden, and said: "The sharpness of this knife is rare in the world. I don't dare say that he can cut off all the other swordsmen, but so far, there is no weapon that he can't slash. ”

Wei Renshi was suddenly quite expectant, and hurriedly urged: "Okay! Quick, try it! ”

"Okay, you're going to see!" Li Chun stood on tiptoe with a smile, with a very strong confidence in his eyes, and said to Wei Renshi: "My knife is extraordinary, and when an ordinary sword encounters, it will be broken." However, in my opinion, this weapon is extremely well forged, and my short knife, this time, I guess it is impossible to cut this weapon. ”

Although he said it modestly, he was suspected of saying it on purpose. Because the pride in those eyes could not be concealed.

Wei Renshi was looking forward to the performance of this weapon made of new steel, so he took a step back, made way of space, and let Li Chun try the knife.

He was eager to see how the new steel produced by the improved method of iron-smelting and steel-making would compare with the famous 100-year-old steel.

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

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

"Hah!" Li Chun took a few long breaths, and then suddenly screamed, and his hand seemed to have a thousand forces to smash down, and the horizontal knife in his hand slashed heavily on the short blade.

His servant did not wait for the blade to fall, but rose from the ground with a hey, and the short blade in his hand slashed upwards with force, meeting the horizontal knife in Li Chun's hand.

Only a dull metal clang was heard, and the two of them actually pushed a few steps away, which showed the great force of the two.

Wei Renshi craned his neck to look there, and the others also hurriedly looked there.
