The molten iron splashed together with the blast furnace, and coupled with the power of the explosion, Fang Bai was not sure whether the water shield technique could withstand it.
Rather than taking that risk, Fang Bai might as well use some new technology.
"Village chief, here are the mercury and steel bars you want."
Bai Qing led a few people to transport a bucket of mercury and two carts of steel bars to Fang Bai's house. During the process, Bai Qing kept looking at the sudden appearance of the rocky building in the middle and couldn't help but ask.
"Village Chief, was this house created using magic?
Can this spell be used to build walls and houses?"
Fang Bai raised his head and glanced at Bai Qing, nodded and said loudly.
"Okay, but I don't have time to repair it. Let's wait a few days.
After the training of this group of mage apprentices is completed in a few days, I will transfer the few with the worst grades to build the city wall."
Bai Qing laughed immediately when he heard this. This was exactly what he had in mind. He never thought about letting Fang Bai build the city wall.
Spending so much time building the city wall, Fang Bai might as well do other things, Bai Qing felt it was not worthwhile.
"Okay, village chief, you're busy, I'll leave first?"
"okay."
When Fang Bai saw Bai Qing leaving, he was still immersed in research.
"Fireball."
Fang Bai smacked his lips and looked at the spell model in the spell book.
This is not the spell model given as a gift when he changed his job, but the fireball spell model on the Fire Bull.
Compared to Fang Bai, the flames of this spell model have some adhesion ability after the fireball explodes, which is secondary.
The main reason is that the flame temperature of this layer is very high and can be maintained for a long time. Fang Bai feels that it may be used in metal smelting.
But when Fang Bai saw this spell model, he couldn't help but think of Fire Ox.
"By the way, the fire ox should be pulling the cart now, right?"
Fang Bai muttered that Huo Niu had been tricked by Bai Qing into pulling a cart a few days ago.
It can only be said that even though this fire bull has turned into a monster, it still maintains goodwill and trust in humans.
Fang Bai shook his head and erased this distracting thought. While calculating, he modified the spell model in front of him bit by bit.
"Here is explosion, here is fire element compression, here is adhesion, here is temperature"
Fang Bai held a pen and tapped lightly on the draft paper.
"It's best to wipe out all the explosions, leaving nothing behind. The fire element is compressed and cannot move. This is part of the source of high temperature and power.
The adhesion can also be appropriately weakened. There is no need for high adhesion in molten iron smelting, but the temperature."
Ta-ta!
Fang Bai's pen tip tapped the spell structure a few times.
"De Laman!"
Fang Bai pondered for a moment and then began to modify the fireball spell model.
Reduce the blasting power as much as possible and increase the flame temperature as much as possible.
Modifications again and again, experiments again and again.
Fireball is a one-level spell. Considering Fang Bai's current spell model attainments, it is not difficult to modify it on the basis of a large framework.
Soon, a formed spell model was released in Fang Bai's hands.
Wave!
With the power of a "King of Thunder" explosion like when I was a child, red and blue flames clung to the surface of the iron block and burned fiercely.
This powerful explosion in the furnace is no longer enough to shake the furnace.
And with the effect of a little trick, a steady stream of wind poured into the furnace to provide enough oxygen.
At the same time, Fang Bai maintained the input of the fire element and maintained the existence of the flame.
Gradually, the inner wall of the furnace and the surface of the steel turned red. Under the continuous flames, in the semi-enclosed space, the temperature concentrated on the red steel.
As time goes by, even steel gradually softens and melts under this high temperature.
"Crack!"
Hearing the sudden sound, Fang Bai was slightly startled and looked at the sudden cracks on the surface of the furnace.
"Fuck, is it cracked?"
"Forget it, don't worry, stone wall technique!"
Fang Bai immediately constructed a spell model, and then a stone wall spell fell on the furnace, which not only repaired the gaps in the furnace, but also thickened and strengthened the furnace.
After this little episode, there were no accidents during the smelting. The steel gradually turned into a pool of red molten iron in the furnace, which whetted one's appetite just by looking at it.
Fang Bai was about to purify it, but he found Wang Kai came in with thirty people.
"Village chief, I have brought all the people back. This is their information."
Fang Bai immediately stopped what he was doing and took the document, but did not read it. Instead, he put it aside and handed the other document next to him to Wang Kai.
"You go and let them practice the postures according to the above description. For other things, we can do it after one round of practice.
Only ten remain."
Fang Bai said lightly.
Although the most important thing in cultivating knights is loyalty and trust, talent is closely followed.
If it is really not suitable for knights, then forced training will have no effect.
"clear."
Wang Kai led the people and left. After walking far away, he found an open space and began to teach everyone the practice postures according to the requirements in the information, while Fang Bai continued his experiments.
"It's quite complicated."
Fang Bai frowned slightly after sensing the frequency of steel, and immediately planned to clean it up, but hesitated after thinking for a moment.
"Steel is the name of an iron alloy containing 0.02% to 2.11% carbon.
If all the carbon and other things in steel are removed, it will become pure iron, and carbon can basically be called the skeleton of steel.
Pure iron without carbon is too soft to be considered an elemental material."
Fang Bai frowned slightly.
"Many other trace elements are added after careful preparation."
While Fang Bai was thinking, he sensed that there were still some chaotic frequencies in the molten iron. Such complex frequencies simply made Fang Bai upset, and the frequencies were not uniform enough, so it might be difficult to achieve resonance.
"Forget it, pure iron and molten iron that retains some carbon are both made. As for other cluttered frequencies, all are removed.
No matter how good the performance is, if it cannot become an elemental metal, it will be in vain."
Elemental materials improve the properties of the material itself too much.
Just like the carapace on a World of Warcraft, although the ordinary carapace material is also very hard, it is within the understandable range, and there is still a big gap between it and steel.
However, the real elemental material carapace can surpass steel in terms of hardness and toughness!
In addition, it can also store elements and block elements. The difference is simply huge. This is an enhancement in all aspects!
Even the carapace can be strengthened to this extent by being transformed into elemental materials, let alone the already extremely hard steel!
Fang Bai immediately used the resonance characteristics of his mental power to continuously purify the molten iron, and at the same time, he had to distinguish the frequency of carbon in it to maintain an appropriate ratio.
When Fang Bai cleared away most of the cluttered frequencies, the frequencies perceived by Fang Bai had tended to be unified, and seemed to have reached a unified resonance standard, however.
