Sean endured this extremely domineering sour taste, chewed the nettle fruit to shreds in a few bites, and hurriedly swallowed it without even spitting out the core. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Even so, the strange taste of sourness in the mouth still rushed to the door of the brain in waves.

Although I have long heard others talk about the miraculous effect and more "magical" taste of this fruit, I have done a long time for myself to build up my mind before eating it, but the taste that is so sour that I have no friends is defeated in an instant as soon as I enter it.

No wonder the old hunter who sold his fruit smiled gloatingly after receiving five silver wolves, the smell of this thing was really not something ordinary people could bear.

However, after these fruits were eaten, Sean did feel refreshed, and the fatigue of staying up late to work was swept away.

I saw him sweating on his forehead, panting heavily, and pulling the bellows while enduring the "sourness". The hanging charcoal burned more and more in the strong wind he sent, and the golden flames danced happily, and the flames in the furnace were steaming.

After tossing and turning like this for a while, through the transparent walls of the flame crystal pot, Sean finally saw that the iron ore had completely collapsed into a red porridge-like melt under the continuous burning of the high temperature, and the charcoal and other accessories that had been put in it earlier had long been burned out.

Generally at this time, the smelting process of traditional foundries is basically over.

It's just that most people don't know that there is a heat-resistant, transparent, and almost high-quality material born for smelting. Many foundries use cheap clay crucibles for smelting, and the melting of the iron ore inside the vessel cannot be observed.

Therefore, the mastery of the heat and the selection of auxiliary materials during smelting have become the secret of many casting masters.

They either relied on the inheritance of the family, or relied on their own understanding, a lot of strange auxiliary materials in a variety of different proportions and iron ore together sealed in the clay crucible, and then added and deleted fuel and controlled the air intake to observe the smelting effect at different furnace temperatures.

Eventually, there were some people who used this method to smelt the high-performance metallic iron, and they proudly named it after their surnames, such as Armani iron, Hermès iron, and Chanel iron, and passed down these smelting recipes from generation to generation using the most top-secret methods.

Although these brand-name irons smelted in a low-temperature environment have surpassed ordinary large-scale goods in terms of quality, there is still a very big gap compared with the light and strong Mithril and the indestructible Dragon Steel.

"Sean, the elves' lightness to the terrifying starfall Mithril is a godsend, humans don't have it, dwarves don't have it, but the Mithril mine is limited after all, and there will always be a day when it will be used up after thousands of years. For humans, the dwarven lava dragon steel is the real competitor. ”

"Because the dwarves also use iron ore?"

"That's right, they also use ordinary iron ore with a huge output, and before the advent of Dragon Steel, the iron tools made by the dwarves did not surpass us much in quality. ”

"Then how are we going to catch up with Long Gang, father?"

"Molten iron, you must get completely melted molten iron, so that the auxiliary materials can completely remove those impurities in the ore and make real steel!"

Forge real steel.

It was Sean's father, the master foundry Roger Thembur, the most brilliant achievement of his life.

It has now been passed into Sean's hands.

At this moment, Sean stopped pulling the bellows, picked up a cast iron long stick and inserted it into a hole reserved in the lid of the flame crystal pot, and after half a turn, he picked the lid upward.

Although Yunying Flame Crystal is extremely resistant to high temperatures, it is also thermally conductive, and it has become extremely hot after most of the night's baking, and it cannot be touched at all, so the later operations can only rely on tools.

After opening the lid, Sean picked up a few pieces of limestone and dolomite from the pile of trimmings on the ground next to him and threw them into the pot, according to his father's research, the elements contained in these light gray stones can effectively separate the impurities in the iron ore.

Sean then threw in a small piece of rock iron, which is said to contain a substance that can further strengthen the rigidity of metal, so Sean and his father also listed it as one of the important excipients added in this link after experiments.

At this point, all excipients have been added, except for the forbidden blood.

Next, it's time to witness the miracle.

With the help of a long cast-iron stick, Sean re-covered and tightened the lid that had been burned hot on the container, and then used the tip of the stick to pick open a small round baffle on the left side of the jug, revealing a hole hidden underneath.

When my father carved this piece of Yunying flame crystal into a pot, he specially carved a hole in the body of the pot, and inserted a hollow pillar of flame crystal obliquely downward, until it stretched almost close to the bottom of the pot, in order to leave a passage to the bottom of the pot from the outside.

At this time, the flames in the shaft furnace were beginning to show signs of abating, but Sean ignored it completely, and instead walked to the side of the cave that was facing the hole in the body of the pot, and sat down at a distance, then raised his hands and began to recite the incantation slowly but clearly.

Soon, a whirlwind faintly appeared between Sean's hands.

Sean has been practicing this kind of wind magic since he was a child, although the craftsmen of the dwarf kingdom invented the bellows a long time ago and quickly spread it to the entire continent, but just as practicing fire magic helps to condense the flames, the foundries of various countries have never relaxed their practice of wind magic.

After all, bellows are designed to be large and bulky in order to blow up strong winds, which cannot be used in many occasions that require fine machining. This is where the wind magic mastered by the foundry can be used.

Let's say what's going on now.

A moment later, there was a loud whistling sound between Sean's hands, and the dirt and gravel around him were blown away, and even the flames in the shaft furnace in the distance began to shine brightly and dimly under the influence of the strong wind in Sean's hands.

But it didn't matter, my father had said that it didn't matter if the charcoal fire was extinguished at this time, Sean concentrated on controlling the growing cyclone, condensing it into a thin wind line, and sending it through the hole in the body of the pot.

He had conducted many experiments with his father before, and he had a good idea of how to control the air volume and speed.

Through the translucent walls of the container, he soon saw that the wind he had sent had successfully pushed the porridge-like molten iron at the bottom of the chamber into a small cavity, indicating that this step had been very successful, so he stopped casting the spell and waited patiently for the violent reaction to come.

The power of nature is so amazing, it seems like only a moment has passed.

The molten iron boiled.
