I build a floating city in the last days

Chapter 150 Knight Selection
blast furnace explosion
The molten iron splashed with the blast furnace, and with the power of the explosion, Fang Bai was not sure whether the water shield technique could withstand it.

Instead of taking that risk, Fang Bai might as well use some new technology.

"Village Chief, here are the mercury and steel bars you asked for."

Bai Qing led a few people to transport a bucket of mercury and two carts of steel bars to Fang Bai's house. During this process, Bai Qing kept looking at the suddenly extra rock building in the middle, and couldn't help asking.

"Village chief, is this house made by magic?
Can this spell be used to repair fences and houses? "

Fang Bai looked up at Bai Qing, nodded and said aloud.

"Okay, but I don't have time to fix it, so wait a few days.

After the training of this group of mage apprentices is completed in a few days, I will transfer some of the worst grades to repair the city wall. "

Bai Qing laughed immediately when he heard the words, he had exactly this idea, he never thought of asking Fang Bai to build the city wall.

With so much time spent on repairing the city wall, Fang Bai might as well do other things, even Bai Qing felt that it was not worth it.

"Okay, the village head, you are busy, shall I go first?"

"okay."

Seeing Bai Qing leave, Fang Bai was still immersed in the research.

"Fireball."

Fang Bai smacked his lips, looking at the spell model in the spell book.

This is not the spell model given by his job change, but the fireball spell model on the fire bull.

Compared with Fang Bai, the flame of this spell model has some attachment ability after the explosion of the fireball, which is second.

The main reason is that this layer of flame has a high temperature 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 Bull.

"By the way, Fire Ox should be pulling the cart now, right?"

Fang Bai muttered, as early as a few days ago, Huoxing was tricked by Bai Qing to pull the cart.

It can only be said that even if this fire bull becomes a monster, it still maintains its goodwill and trust in humans.

Fang Bai shook his head, erased the distracting thoughts, and modified the spell model in front of him bit by bit while calculating.

"Here is explosion, here is fire element compression, here is adhesion, here is temperature"

Fang Bai tapped lightly on the draft paper with a pen in his hand.

"It's best to wipe out all the explosions, and there is nothing left. The fire element can't be compressed, which is part of the source of high temperature and power.

Adhesion can also be appropriately weakened, molten iron smelting does not need too high adhesion, and the temperature."

blah blah blah!

Fang Bai tapped the spell structure a few times with his pen tip.

"Delaman!"

Fang Bai pondered for a moment and then began to modify the spell model of Fireball.

Reduce the blasting power as much as possible and increase the flame temperature as much as possible.

Revision after modification, experiment after experiment.

Fireball is a first-level spell, and with Fang Bai's current spell model attainment, it is not difficult to modify it on the basis of a large framework.

Soon, a formed spell model was released from Fang Bai's hands.

Wave!
Just like the power of the "Thunder King" explosion when he was a child, the fiery red and blue flames adhered to the surface of the iron block and burned blazingly.

Exploding in the furnace with this power 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, maintaining the existence of the flame.

Gradually, the inner wall of the furnace and the surface of the steel became red, and under the continuous burning of the flames, in the semi-enclosed space, the temperature gathered on the red steel.

With the passage of time, even steel gradually softens and melts at this high temperature, and gradually.
"Crack!"

Hearing the sudden sound, Fang Bai was slightly taken aback, looking at the crack that suddenly appeared on the surface of the furnace.

"Damn, cracked?"

"Forget it, it's okay, stone wall!"

Fang Bai immediately constructed the spell model, and then a stone wall spell fell on the furnace, which not only repaired the gaps on the furnace, but also thickened and strengthened the furnace.

After this episode, there was no accident in the smelting, and the steel gradually turned into a pool of red molten iron in the furnace, which whetted the appetite just watching it.

Fang Bai was planning to purify it, but found that Wang Kai brought thirty people in.

"Village Chief, I brought everyone back. This is their information."

Fang Bai immediately stopped what he was doing and took the document, but he didn't read it, but put it beside him casually, and handed the other document next to him to Wang Kai.

"You go and let them master the postures according to the above description, and other things, let's talk about it after a round of practice.

Only ten are left. "

Fang Bai said lightly.

Although the most important thing in cultivating a knight is loyalty and trust, talent is a close second.

If it is really not suitable for knights, then forcibly cultivating them will have no effect.

"clear."

Wang Kai led the people and turned away. After walking far away, he found an open space and began to teach everyone the practice postures according to the requirements in the materials, while Fang Bai continued his experiment.

"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 while.

"Steel is the name given to an iron alloy containing [-] to [-] percent carbon.

If all the carbon and other things in the steel are cleaned up, it will become pure iron, and carbon can basically be called the skeleton of steel.

Carbon-free pure iron is too soft to be considered an elemental material.”

Fang Bai frowned slightly.

"And many other trace elements are added after careful deployment."

While thinking about it, Fang Bai sensed that there were still some chaotic frequencies in the molten iron. Such a chaotic frequency made Fang Bai feel upset, and the frequencies were not uniform enough, so it might be difficult to achieve resonance.

"Forget it, make part of the pure iron and the molten iron that retains a part of carbon, and remove all other messy frequencies.

No matter how good the performance is, it can't be an elemental metal, and it's useless. "

Elemental materials have greatly improved the properties of the material itself.

Just like the carapace on the body of a monster, although ordinary carapace materials are also very hard, they are also within the understandable range, and there is still a big gap between them and steel.

However, the real elemental material carapace can completely surpass steel in terms of hardness and toughness!

In addition, it can also store elements and block elements. The gap between them is simply too large. This is an all-round enhancement!

The carapace can be enhanced to this point by turning it into elemental materials, let alone the already extremely hard steel!
Fang Bai immediately used the characteristics of spiritual resonance to continuously purify the molten iron, and at the same time distinguish the frequency of the carbon in it, so that it maintains an appropriate ratio.

And when Fang Bai cleared most of the cluttered frequencies, the frequencies Fang Bai perceived had tended to be unified, and seemed to have reached the unified resonance standard, but...
