Everyone entered this courtyard for the first time and looked at Hong Xiaobao differently.

Hong Xiaobao is in the extreme realm, and the two thousand catties of boulders are easily lifted, what is this?

Whew-

Whew-

The tongue of fire continued to rise, and there was a tendency to become more and more violent, and the sparks in the courtyard danced wildly, and everyone took a step back in unison.

"Hehe, it's lively!" Suddenly a faint voice came, everyone was stunned, looked back, and a few more people came, the first one of them had a close-fitting robe outlining the muscles of the whole body, and his temperament was extraordinary, looking at the dark skin, he was also a blacksmith.

"Shopkeeper Li. ”

"Nice owner. ”

Everyone immediately greeted each other, and after greeting everyone slightly, Shopkeeper Li looked at Hong Xiaobao, looked at the tongue of fire churning in the furnace, nodded and continued to praise: "This arm strength is extraordinary, this little brother is afraid that he is a monk of the flesh fetus double forging realm!"

Hong Xiaobao didn't care about him, stood up, took out a small bottle in his arms, took out the lead tongs to remove the coal, and then poured out a little water from the bottle, put it in his palm and shook it violently......

Zi –

Zi –

Whew-Teng——

After a few sounds, the tongue of fire that had calmed down slightly after the bellows stopped came out again, and everyone was shocked:

"What is this thing?"

"Mercury?"

"It shouldn't be mercury, mercury is not resistant to high temperatures, I'm afraid it will evaporate all at once. ”

"Master Guo, is this ......?" Shopkeeper Qin looked at Master Guo suspiciously, and everyone instantly fell silent, yes! There is a master who is famous all over the city, listen to what he has to say.

"......" Master Guo was stunned, he didn't know this thing! ”

"Oh......"

"That's it!"

Everyone sighed, but two or three of them were speechless, and there was a difference between what he said and what he didn't say!

"Guo Zhangfei, observe it, this is called the underground silver pith, it is a priceless treasure generated in the 10,000-year-old cave, what is the unique formula?" Hong Xiaobao is the most wrong thing to see is this Master Guo, hehe said happily: "If you don't understand, don't talk about bad people!"

Master Guo's leopard eyes widened again and pointed at Hong Xiaobao: "Who is Guo Zhangfei? You are Guo Zhangfei! The old man's surname is Guo Mingyuan, and the word cultivator!"

"Okay Guo Zhangfei," Hong Xiaobao said, but as he spoke, he urged a second bonfire array, the two bonfire arrays did not have much impact on the overall temperature, and in the eyes of everyone, this was all the effect of that bit of silver liquid.

How did they know that this was just something that Hong Xiaobao had prepared to force out the impurities in the dark iron? It had nothing to do with the underground silver pith!

Hong Xiaobao squatted down again and pulled up the bellows, the tongue of fire churned again, and Hong Xiaobao urged the third bonfire array in this gap, the temperature of the thin twelve fine flames was extremely high, and the silver liquid poured on the dark iron was burned to spread out in four, covering the dark iron little by little, and after a while, a drop of extremely turbid black water overflowed little by little.

At this time, Hong Xiaobao had already urged the fifth bonfire array, and the temperature of the furnace fire had changed significantly under the blessing of the five bonfire arrays, and all the blacksmiths were shocked, and in some extreme cases, they would also use some combustion-boosting things, such as common oil, and then use fire fox oil if they were a little more luxurious. Although these things can burst out at extremely high temperatures in a short period of time, they will be extinguished in a moment, and they are not as durable as Hong Xiaobao's underground silver marrow. Everyone was shocked, and they all whispered to each other about the origin of the silver pith.

It's just that it's completely made up by Hong Xiaobao, how can anyone know?

"Master Guo, is the silver chalcedony used to fuel fire?" asked a blacksmith, his face a little envious, although he also thought that this thing would be very expensive, but what if it was cheaper?

Guo Yuan's face twitched slightly, he didn't know about this thing, but as the chief foundry in Leiyin City, it was hard to say that he didn't know, so he smiled and said, "I seem to have heard of it, but it's been a long time, and I don't have any impression anymore." ”

When Hong Xiaobao urged the eighth bonfire array, under the high temperature of the thirty-two fine flames, the fire temperature in the entire furnace rose sharply, and it was already full of green flames!

The four bellows are called fine fire, medium fire, green fire, and there is an idiom called "pure green fire", green is the highest temperature flame color in the ordinary sense, and it is also a little troublesome to feed the green fire when refining, and it takes several big men to take turns to fight, and they are often tired and half dead, and everyone is shocked to see Hong Xiaobao give birth to green fire so easily!

"Green Fire!"

"I actually fed the green fire alone!"

"It's so strong!"

"Is this thing difficult? It's hard for you to give birth to this green fire?" Hong Xiaobaole said: "It's too easy, hey!"

Everyone's faces twitched slightly, and they all looked sullenly.

After a while, Yin Jiuyou said that the fire was enough, Hong Xiaobao immediately got up, pushed the charcoal away with lead tongs, and took out the dark iron that had turned dark orange one by one - if it was other materials, most of them would melt into water under the green fire for so long, and the dark iron only showed a dark orange appearance, which was enough to see its strength.

Just put the dark iron on the big anvil, and the contact between the dark iron and the anvil immediately sneered and smoked, and the anvil had a tendency to be melted!

Everyone was shocked:

"The black iron has melted the anvil!"

"That's how hot it is!"

"Oh my God!

"It's been several years since I last saw the anvil, and today I'm lucky enough to see it again!"

At this moment, everyone is coveting Hong Xiaobao's underground silver marrow, thinking about when they can get a copy, you must know that the temperature is not too high for the refining weapon normally, but it is too difficult to use it, and the chickens and dogs may be able to raise the temperature after jumping for a while.

"A group of ignorant mountain people," Yin Jiuyou said contemptuously: "Qing Yan has become like this, what if you see Bai Yan?"

"Bai Yan?" Hong Xiaobao's heart immediately moved: "Old man, get it! Today, the master has to scare them stupidly!"

"Ignorance!" Yin Jiuyou scolded unceremoniously: "It takes at least a hundred bonfire arrays to feed the white flames, this furnace is now almost at its limit, ten bonfire arrays will be completely melted, and the dark iron can barely withstand the white flames, but the high temperature will last for a full few months, can you wait?"

"No, you can't. Hong Xiaobao said simply, fished out all the nineteen pieces of dark iron, picked up the sledgehammer and immediately banged it.

"Oh my God!
