As soon as Kitagawa knocked the charcoal into pieces, there was a heavy breathing sound outside the door

"Your Excellency Higgs! Are you looking at that enough? ”

When Beichuan turned around, William outside the door was already holding a sack, stepped over the threshold and walked in and put the sack in front of him with a 'plop'. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Coming back so soon? It's all sand? Kitagawa reached for the seal on the sack.

Speaking of this sand, which can only be used by ordinary fishermen to wash shellfish occasionally, but here is a long way from the sea, and it is possible to get such a large bag of sand so quickly, this William has some means!

"The family only came back yesterday and hasn't opened it yet, I threw a gold coin, and they gave it to me very happily!" William said nonchalantly.

"A gold coin?"

Beichuan gasped, you guy is also generous! If you give you a gold coin, people will definitely want to give it to you, maybe they will have it if you show a little meaning!

William also seemed to understand Beichuan's expression, waved his hand and said, "Money is a trivial matter, can you see if this sand can work first?" ”

Beichuan Yiyan reached into the sack and grabbed a handful of fine sand, and found that the sand was crystal clear and clean, as if someone had carefully selected them one by one.

After seeing the grit in the sack, Beichuan nodded to William and said, "This sand can definitely be used, and the quality is quite good!" ”

"So what are we going to do next?" William seemed a little impatient, after being a blacksmith for so many years, he suddenly heard about a new material from a stranger that he had never seen before, and he naturally had some itching.

"When you went to get the sand just now, I had already processed the charcoal, and we had to mix these three materials in a certain proportion, the amount of iron sand determines the toughness of the material, and the charcoal and gravel determine the stiffness..."

"To mix sand in it? Belch! As complicated as it sounds, what about the proportions? William asked.

"Proportions? I'm afraid I'm going to have to give this a try.,How about the first three of each third? Beichuan replied touching his chin.

William smiled bitterly, he only now realized that this guy named Higgs didn't seem to be so reliable...

"Then try it first?"

――――――――――

Saying that, William stepped on a pedal bellows, only to see the orange flame in the furnace soar violently, Beichuan grabbed two handfuls of each of the three materials and mixed them evenly, found a gap and threw them in.

Wow!

Because the mixed powder was mixed with broken charcoal, the flames that Kitagawa sprinkled into the furnace gushed out as if they had been sprinkled with hot oil, and the orange-red flame tips had a tendency to slowly turn blue...

But charcoal, after all, only made up a third of it, and then disappeared after causing a burst of flames...

The rest of the powder quickly covered the surface, and the orange flames licked at the intruders, sharing their enthusiasm to the fullest. After a while, the black iron slag began to turn red and soft, and it would soon liquefy.

Kitagawa stared closely, the changes in the furnace...

To be honest, he hadn't been worried about the iron sand from the beginning, because he had seen William use the furnace to make molten iron, and it would be no problem to melt the iron sand from the furnace. So now it's not that that that he's mind, it's the gravel...

He had thought of many possibilities before, but just now he realized that he had only overlooked one thing--that is, the melting points of the substances in these two worlds were very likely to be different, or they were simply two substances!

It wasn't grit in that sack!

Since the 'grit' was put in, there has been no sign of melting at all, let alone softening or even redness!

The iron sand had begun to melt into liquid, slowly dripping to the bottom of the furnace, and the grit did not react at all...

"William, you're trying to increase the firepower!" Beichuan turned his head to William Dao with a calm face.

"Okay!" William snorted and stomped hard.

As the so-called wind fuels the fire, the fire in the furnace soars again with the help of this wind flame, and the tongue of fire instantly turns into a pillar of fire that soars into the sky, and then the heart of the flame has turned blue.

The temperature around the stove skyrocketed instantly, except for Kitagawa and William, who stayed by the stove all year round, everyone else subconsciously jumped back...

Beichuan is naturally not too happy, compared to the others, he is the closest, if it weren't for the passive skill [Quick Response] just now, after perceiving the abnormal restlessness of the air, he subconsciously flashed. At this point, he may have to say goodbye to his hair.

And even though Kitagawa had already flashed the flames just now, his face was blackened by the smoke that rushed up...

I didn't have time to pay attention to the 'smoky makeup' on my face, and after the flames faded, Kitagawa immediately took a look.

At this glance, his face suddenly became ugly - those 'grit' did not move at all!

Liz on the side was the first to notice the change in Kitagawa's expression...

"How's it going? What happened? ”

Kitagawa frowned, his eyes staring at the sand in the furnace.

"The temperature is not enough, this fire can still be..."

Before Kitagawa could finish speaking, he was interrupted by William.

"No, this is already the maximum firepower, and I dare say that in the whole of Tiha, I can't find a furnace with a higher temperature than this stove of the master..."

"That..."Beichuan stopped talking.

William's eyelids drooped and he said coldly: "Okay! Your Excellency Higgs, this method you are talking about may just be your imagination for a while, but in fact, this method cannot be realized at all, right? Thank you for sharing this idea with me, but for now, please come back, I'm going to forge a knife for 'Lynn'..."

“...”

Kitagawa was silent, now he really couldn't find a way to melt the grit of this world.

It looks like just grit, why can steel be melted, but this can't...

Beichuan took a deep look, William, who was already sorting out the tools, sighed silently, in fact, if it can really be melted, it is really possible to make sponge iron, and then forge jade steel, but now nothing is possible.

"Captain Higgs, please let me try..."

"Oh..."Beichuan agreed listlessly, and walked out the door with his feet raised.

Halfway through, Beichuan suddenly woke up..., who was talking just now? When he looked back, he realized...

"Hey! ...”

The girl limped one foot and came to the stove with her hands stretched out like jade, clenched, interlocked, and stood quietly by the stove, and the scorching flame did not seem to affect the girl at all, but like the green leaves in the flowers, the gray-haired girl was more beautiful and refined.

At this time, she stood alone by the fire, like a flaming spirit, the boiling flames around her gently caressed her skin, but did not hurt her in the slightest, but seemed to be guarding her.

For a second...

Two seconds...

...

Before I knew it, the orange-red flame began to change quietly...
