After receiving an affirmative reply from Anvil, Duke left the dwarven gathering with some joy.

After that, he walked with the soldiers to the old Neil of the blacksmith shop not far away.

This conversation with the dwarves made him realize that making steel is also the first priority.

And now that a large number of energy supply magic stones have been dug up, it is possible to realize the idea of continuously refining steel that I told Old Neil before.

So he finally decided to go to Old Neil to confirm and give him some indicators and tasks.

When he arrived at Old Neil's blacksmith's shop, he was surprised to find that Lenia was already standing there with her breasts crossed, staring at a dwarf like an overseer.

Duke took a closer look and realized that the dwarf running around was the unlucky thing who shot at him yesterday, and that Lenia was so busy with what she had planned.

"Yo, Lenia, what a coincidence. Duke greeted Lenia from behind.

Lenia greeted him and kept staring at the dwarf.

Curious, Duke stepped forward and asked, "What are you doing?"

Lenia Nunu said, "That little man said he could help me fix my armor, and if he didn't, I would beat him up, so now I have to keep an eye on it, and I can't let that kid run away!"

It was only then that Duke noticed that the dwarf was deftly tinkering with a pair of armor with a hammer and a mass of unknown material, making a clanging crunch.

"I think he also has some skills, so you don't have to be so distrustful, right?"

Duke couldn't help but intercede for him, after all, he didn't do anything to himself when he shot in a hurry, so he wouldn't be treated like this.

Lenia said with some noncommittality: "Who knows how he did until the end?"

Duke shook his head, gave the dwarf a self-contained look, and then left him alone with the guards and went straight into the backyard of the blacksmith's shop to look for Old Neil.

And old Neil had heard the lord's voice in the backyard as early as before, so he waited at the backyard door in advance, and when he saw Duke coming in, he bowed down and said something flattering.

"I'd like to see the furnace again. Duke was a little helpless to stop his chattering words and directly stated the purpose of the trip.

Old Neil was a little incomprehensible to the strange hobbies of the noble lords, not only did the lord come to his blacksmith shop every once in a while, but the knight lady also sneaked a dwarf over every once in a while.

But he didn't dare to say anything, so he could only respectfully give way to the entrance and let the lord go in and visit.

As soon as Duke stepped into the courtyard, he felt a wave of heat and the sound of tinkling steel.

There were a dozen or twenty people working in the courtyard, and the iron-making stove, which had been quiet last time, was now blazing.

There was also a glimmer of magic around the stove, and a thick column of black smoke was spewing from the tall chimney.

Due to the expansion of the Duchy of the North and the increase in population, the demand for steel in all aspects has skyrocketed by an order of magnitude, so the blacksmith shop, which was once somewhat quiet, is now extremely busy.

"How do these magic runes power up? Do you also use energy supply magic stones?"

Duke suddenly asked Old Neer, last time he vaguely heard what energy supply runes were used to provide energy, and it seemed to be different from the energy supply magic stone.

"No, no, no, of course not, our annual income is not enough to buy an energy magic stone, how can we use such a luxury thing. ”

Old Neil hurriedly waved his hand and said, then led Duke to the back of the burning stove, pointed to a rune with a lilac shimmer and explained: "We use this kind of magic energy supply rune that draws magic power directly from nature, although the transformation efficiency of this energy supply rune is very low, but it has already met the trace amount of magic needed to make steel. ”

Duke was a little curious to use his spiritual power to feel the magic fluctuations of this rune, and found that the efficiency of this functional rune to absorb and convert magic power was indeed very low.

Of course, this is also due to the fact that there is not a lot of magic in nature itself.

Anyway, he needed to muster up his spirit to feel that little bit of magic power, which was not at the same level at all compared to the magic rune driven by the energy supply magic stone of the anvil just now.

"Then if we improve this and other auxiliary magic runes, or use them to power them with energy supply magic stones, can we make better and harder steel?" Duke gestured behind the furnace and told Old Neil his plans.

Old Neil was stunned, obviously he didn't expect the lord to ask such a question, he had never thought like this before, he frowned and thought for a while before saying: "This is okay to say, but if it is just to improve the quality of steel, it does not need to be so troublesome." ”

He bypassed the stove in front of him and carefully pulled out a small vial of what looked like a clear test tube from the material cupboard, containing a small half bottle of a strange dark blue liquid.

Old Neil gently unscrewed the cork on it like an expensive fine wine, and instantly a strong sour rancid smell penetrated the nostrils of everyone present, rushing straight to the brains, very high.

Old Neil hurriedly stuffed the cork, and said with some embarrassment: "It's been a long time since I forgot its taste, ahahaha......"

Duke hid his nose and took a few deep breaths, but he didn't slow down, and even Lenia outside the door frowned and poked her head out to look around suspiciously.

"It's ...... What is it. ”

It was only with great difficulty that Duke could speak in fits and starts.

"This is a magic potion prepared by the magicians, and just adding a little to the iron smelting can greatly improve the quality of the finished product. ”

Old Neil brought the bottle over to Duke as if he were offering a treasure, and he hurriedly took a step back.

"So if you're just trying to improve the quality of steel, it's not as cheap to use an expensive power-supply stone as it is to use it. ”

After listening to old Neil's words, Duke couldn't help but laugh and cry.

If the energy supply magic stone really needs to be bought from the outside, of course, it is more affordable.

But now the energy supply magic stone is Chinese cabbage, and the amount is enough, so if you use this method at the end of the year, it will increase consumption.

However, if you combine the two, it seems that it also works well.

"Let's not talk about this, just say whether it is useful to use the energy supply magic stone. Duke waved his hand and said with a pride that he was always good at it.

"Uh...... Of course you can. ”

"Okay, then you do it!"
