I Build a Floating City in the Apocalypse – Chapter 148

Chapter 148

“Destruction, destruction, destruction.”

Fang Bai glanced around, instantly locking onto a piece of iron.

“Iron, or rather, metal!”

“Metal has high purity, a simple internal structure, and can be ‘destroyed’ by melting.”

“And after melting and solidifying again, it becomes a metal block again.”

“However, pig iron is actually an iron-carbon alloy, and the carbon content of steel is only around 0.03% to 2%.”

“The melting point of steel is relatively high.”

Fang Bai pondered for a moment, then immediately found some tin and a few crucibles.

Compared to steel, the melting point of tin is only about two hundred degrees, making it incredibly easy to melt.

Fang Bai lit a fire and then cut the tin into small pieces, placing them into the crucible.

As the crucible heated up, the tin inside gradually melted, transforming into a small pot of silver-white liquid.

Fang Bai tried his old trick, using his Mental Power to sense the frequency of this liquid.

Even in a liquid state, the frequency of the metal was very low and stable, making it difficult to capture, no different from before.

Fang Bai spent some effort before finally capturing its frequency. The moment he sensed the frequency, a gleam of joy appeared in his eyes.

“Sure enough, the frequency of the molten tin has been unified.”

“Although there are still some chaotic frequencies, they should be the frequencies emitted by the impurities within, which are within an acceptable range and harmless!”

Overjoyed, Fang Bai immediately prepared to control a wisp of fire element to adjust its frequency, but he suddenly thought of something.

“Wait, if I can interact with and interfere with it when the frequencies are the same, and pass directly through it when the frequencies are different, then…”

Fang Bai felt like he had discovered a cheat, a cheat that belonged to all mages, to all those with Mental Power.

“Doesn’t this mean that as long as there is resonance, I can completely filter out all the impurities in the tin?”

“Doesn’t this mean that as long as I want, I can extract the pure element of any metal, obtaining 100% pure metal that has never existed in history?”

Fang Bai was slightly startled. He immediately gave up on capturing the frequency of the main part of the molten tin and instead directly captured those chaotic, tiny frequencies.

Sensing one of them, Fang Bai’s Mental Power instantly resonated with it.

Then, Fang Bai formed his Mental Power into a plane and used this plane to sweep through the molten tin.

The airtight plane passed directly through the molten tin without causing a single ripple, as if it existed in two different parallel worlds.

And when this Mental Power touched the impurities within, they were directly captured by the Mental Power and pulled out of the molten tin.

Fang Bai used his Mental Power to sense the minuscule impurities, discarding them. His Mental Power then transformed into the next frequency, filtering again.

Time and time again, with each filtration, the chaotic frequencies within the molten tin decreased by one, and the purity of the molten tin increased slightly.

Finally, when Fang Bai could not capture any chaotic frequencies in the molten tin, all the frequencies on the molten tin were unified, with only one frequency remaining!

Fang Bai sensed the complete frequency, and a sense of satisfaction surged in his heart.

“If someone with OCD were to do this job, it would definitely be very comfortable. If someone with OCD became a mage and learned how to perceive frequencies…”

Fang Bai muttered.

“Then all the alloys or metals with impurities he encounters would be purified into pure elements by him.”

Fang Bai thought with a chuckle.

“100% pure tin… well, at least within the range that my current Mental Power can reach, I can guarantee that it is 100% pure.

And even if it doesn’t reach 100% in reality, it must be quite pure, definitely infinitely close to 100%.”

Fang Bai was also very pleased. Although he didn’t consider himself to have OCD, seeing the chaotic frequencies and the impurity-containing molten tin being unified and purified to the extreme, a sense of satisfaction involuntarily rose in his heart.

This is probably human instinct, haha.

“Through this method, it should be said that I can smelt and purify all ores or substances that can be melted and whose frequencies can be captured, and obtain high-purity single elements, right? This is convenient.”

Fang Bai said comfortably, then recorded this technique in his notebook.

However, at this moment, the manuscript in his mind opened again and condensed into a pen.

“No way, no way? Manuscript, you wouldn’t not have even recorded this method of purifying metal, would you? That’s great.”

Fang Bai muttered.

“Wait a moment, wait a moment, let me refine it a little more before I say anything.”

Fang Bai didn’t record it immediately. Instead, he turned his gaze back to the molten tin.

Sensing the pure frequency, Fang Bai’s Mental Power enveloped a batch of elements, forcibly changing their frequency through resonance.

“Wait…”

Fang Bai suddenly realized a problem.

“How do I change the frequency of the elements?”

“Forcibly change the frequency of the elements? The reason why my Mental Power can interact with elemental power is that the frequency of my Mental Power is the same as the frequency of elemental power. Resonance is achieved, so my Mental Power can capture elemental power.

Changing the elemental power of my Mental Power will only lead to my Mental Power being unable to interfere with elemental power anymore, not to a change in the frequency of elemental power.

It’s also nonsense for me to capture elemental power, forcibly restrain it, and resonate with it using my Mental Power.

And currently, only Wang Kai has successfully changed the frequency of elements.

And how did he change it?”

Fang Bai pondered quietly, and the answer soon surfaced in his mind.

“Wang Kai’s medium for controlling elemental power is not Mental Power, but himself.”

“Only my Mental Power can interfere with elemental power, which is control.

But Wang Kai’s body itself generates elemental power. With a thought, he can control it without the involvement of Mental Power.

This is not called control, this is called use, direct use.

My control method is resonance, so I cannot change the frequency of elements. But Wang Kai can control it inherently, so elemental power is his own power, and he can freely control elemental power to change its frequency.

This is the fundamental difference!”

In an instant, Fang Bai’s mind became clear.

“So, it still has to be Wang Kai, or rather…”

“It still has to be a Knight.”

Fang Bai seemed to have discovered a new use… oh no, a new future for Knights.

If it was really possible to mass-produce elemental materials, then the Knight profession would have an incredibly bright future!

At this time, Wang Kai was not by his side, as he was busy. Fang Bai didn’t rush to call him, but continued to organize his thoughts.

At the same time, he used the Stone Wall Spell to create a semi-enclosed furnace for later use.

Of course, it was just a furnace shell, not a real blast furnace.

That thing was too technologically advanced. If Fang Bai built one and dared to use it, the blast furnace would dare to explode!

The power would definitely not disappoint.
