I Build a Floating City in the Apocalypse – Chapter 149

Chapter 149

Blast Furnace Explosion

The molten iron splashed along with the blast furnace, coupled with the power of the explosion, Fang Bai wasn’t sure if the Water Shield Spell could withstand it.

Rather than taking that risk, Fang Bai might as well use some new technology.

“Village Chief, here’s the mercury and steel bars you requested.”

Bai Qing brought a few people to transport a barrel of mercury and two carts of steel bars to the side of Fang Bai’s house. During this process, Bai Qing kept looking at the rock building that had suddenly appeared 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 looked up at Bai Qing, nodded, and said,

“Yes, it can, but I don’t have time to build. Wait a few days.

Wait until this batch of Mage Apprentices finishes their training, and I’ll assign a few of the worst-performing ones to build the city wall.”

Bai Qing immediately smiled upon hearing this. This was precisely the idea he had in mind. He never thought of 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 wasn’t worth it.

“Alright, then Village Chief, you’re busy, I’ll take my leave now?”

“Mm, okay.”

Fang Bai watched Bai Qing leave, still immersed in his research.

“Fireball.”

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

This wasn’t the spell model he received from his job change, but the Fireball spell model from the Fire Bull.

Compared to Fang Bai’s, the Fireball from this spell model had some adhesion ability after exploding, which was secondary.

The main thing was that this layer of flame had a very high temperature and could be maintained for a long time. Fang Bai felt that it might be used in metal smelting.

However, when he saw this spell model, Fang Bai couldn’t help but think of the Fire Bull.

“Speaking of which, the Fire Bull should be pulling carts now, right?”

Fang Bai muttered. A few days ago, the Fire Bull was tricked by Bai Qing into pulling carts.

It could only be said that even after becoming a Magical Beast, this Fire Bull still maintained its goodwill and trust towards humans.

Fang Bai shook his head, erasing this distracting thought, calculating and modifying the spell model in front of him bit by bit.

“Here’s the explosion, here’s the fire element compression, here’s the adhesion, here’s the temperature…”

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

“It’s best to completely erase the explosion, leaving nothing behind. The fire element compression can’t be touched, it’s a source of high temperature and power.

Adhesion can also be appropriately weakened, smelting iron doesn’t need too much adhesion, and the temperature…”

Tap, tap!

Fang Bai tapped the tip of his pen on this spell structure a few times.

“Gotta max it out!”

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

Minimize the explosive power as much as possible, and maximize the flame temperature as much as possible.

Modification after modification, experiment after experiment.

Fireball was a One-Ring Spell, and with Fang Bai’s current spell model mastery, it wasn’t difficult to modify it based on the general framework.

Soon, a complete spell model was released from Fang Bai’s hand.

Pop!

After a power similar to the explosion of a “Thunder King” firecracker from his childhood, a fiery red and blue flame attached to the surface of the iron block and burned fiercely.

This power was no longer enough to shake the furnace when it exploded inside.

And with the effect of a minor spell, a steady stream of wind poured into the furnace, providing enough oxygen.

At the same time, Fang Bai maintained the input of fire elements, maintaining the existence of the flame.

Gradually, the inner wall of the furnace and the surface of the steel turned red. Under the continuous scorching of the flames, in a semi-enclosed space, the temperature gathered on the red-hot steel.

As time passed, even steel gradually softened and melted under this high temperature. Gradually…

“Crack!”

Hearing the sudden sound, Fang Bai was slightly stunned and looked at the crack that suddenly appeared on the surface of the furnace.

“Damn, it cracked?”

“Forget it, it’s not a big deal, Stone Wall Spell!”

Fang Bai immediately constructed the spell model, and then a Stone Wall Spell landed on the furnace, not only repairing the cracks on the furnace but also thickening and reinforcing it by another layer.

After this small episode, the smelting process proceeded without incident. The steel gradually turned into a pool of red-hot molten iron in the furnace, looking very appetizing.

Fang Bai was about to purify it, but he found that Wang Kai had come in with thirty people.

“Village Chief, I’ve brought everyone back. This is their information.”

Fang Bai immediately stopped what he was doing and took the information, but didn’t look at it. He casually put it aside and handed another piece of information beside him to Wang Kai.

“Go and have them practice the cultivation postures according to the description above. As for other things, we’ll talk about them after one round of cultivation.

Only keep ten.”

Fang Bai said indifferently.

Although the most important thing in cultivating Knights was loyalty and trust, talent came right after.

If someone was really not suitable to be a Knight, then forced cultivation wouldn’t have any effect.

“Understood.”

Wang Kai took the people and left. Only after walking far away did they find an open space and start teaching everyone the cultivation postures according to the requirements in the information, while Fang Bai continued his experiment.

“Quite impure.”

Fang Bai frowned slightly after sensing the frequency of the steel and immediately planned to purify it, but hesitated after thinking for a moment.

“Steel is the name for an iron alloy with a carbon content of 0.02% to 2.11%.

If all the carbon and other things in the steel are removed, it becomes pure iron, and carbon can basically be called the skeleton of steel.

Pure iron without carbon is too soft, even if it becomes an elemental material…”

Fang Bai frowned slightly.

“And many other trace elements are added after careful adjustment…”

Fang Bai pondered as he sensed the still somewhat chaotic frequency within the molten iron. Such a chaotic frequency made Fang Bai annoyed, and the frequency was not uniform enough, making it difficult to achieve resonance.

“Forget it, let’s make both pure iron and iron with some carbon retained. As for the other chaotic frequencies, remove them all.

No matter how good the performance is, it’s useless if it can’t become elemental metal.”

Elemental materials enhanced the properties of the material itself too much.

Just like the carapace on Magical Beasts, although ordinary carapace material was also very hard, it was still within a comprehensible range, and there was still a considerable gap compared to steel.

But the real elemental material carapace could surpass steel in both hardness and toughness!

In addition, it could also store elements and block elements. The difference was simply too great; it was an all-around enhancement!

If the carapace could be enhanced to such an extent by becoming an elemental material, let alone steel, which was already incredibly hard!

Fang Bai immediately used the resonance characteristics of Mental Power to continuously purify the molten iron, while also distinguishing the frequency of carbon within it, keeping it at an appropriate ratio.

And when Fang Bai had removed most of the chaotic frequencies, the frequency he sensed had become more uniform, seemingly reaching the standard for unified resonance, but…
