I build a floating city in the last days

Chapter 149 Knight's Domain!
"Wreck, wreck, wreck."

Fang Bai glanced around, and instantly locked his target on a piece of iron.

"Iron, or metal!"

"The metal has a 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 about [-]% to [-]%.

Steel has a higher melting point."

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

Compared with steel, the melting point of tin is only about two hundred degrees, so it is too easy to melt.

Fang Bai lit a fire, then chopped the tin into pieces and put them into the crucible.

With the heating of the crucible, the metal tin inside was gradually melted, turning into a small pot of silver-white liquid.

Fang Bai repeated his old trick, using his mental power to perceive the frequency of this mass of liquid.

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

It took Fang Bai a lot of effort to capture its frequency, and Fang Bai's eyes lit up when he sensed the frequency.

"Sure enough, the frequency of metallic tin after melting was unified.

Although there are still some messy frequencies, it should be the frequency emitted by the magazine inside, within the acceptable range, it is harmless! "

The joyful Fang Bai immediately prepared to control a ray of fire element to adjust its frequency, but Fang Bai suddenly thought of something.

"Wait, if my mental power can communicate with it in the same frequency state, can interfere with it, and can directly pass through it in a different frequency state, then..."

Fang Bai felt as if he had found a hang, a hang that belonged to all mages and all spiritual people.

"Does this mean that as long as I resonate, I can completely filter out all impurities in tin?"

"Does this mean that as long as I want, I can extract the elemental substance of any metal and obtain a 100% pure metal that has never appeared before?"

Fang Bai was slightly startled, and immediately gave up capturing the frequency of the most important part of the tin liquid, and instead went directly to capture those tiny frequencies that are chaotic.

Perceiving one of them, Fang Bai's mental power instantly synchronized with it.

Then Fang Bai formed a surface with his spiritual power, and used this surface to pull through the tin liquid.

The airtight surface passes through the tin liquid directly, without causing any waves in the tin liquid, as if existing in two different parallel worlds.

And when this spiritual power touches the impurities in it, it is directly captured by the spiritual power, and then takes it away from the tin liquid.

Fang Bai used his mental power to perceive the tiny impurities, and threw them away. His mental power turned into the next frequency again and filtered again.

Again and again, again and again, each time the tin liquid is filtered, the frequency of disorder is reduced by one, and the purity of the tin liquid is increased a little every time it is filtered.

Finally, when Fang Bai did not capture any random frequencies on the tin liquid, the frequencies on the entire tin liquid were unified, and there was only one frequency!
Fang Bai sensed the complete frequency, and a sense of satisfaction immediately surged in his heart.

"It would be very comfortable to do this job with obsessive-compulsive disorder. If someone with obsessive-compulsive disorder becomes a mage, and let him master the method of perceiving frequency"

Fang Bai muttered.

"Then all the alloys or metals with impurities he has seen will be purified into simple substances by him."

Fang Bai thought with a smile.

"100% pure tin, at least I can guarantee that it is 100% pure in the field that my current mental power can touch.

On the practical level, even if it does not reach [-]%, it must be quite pure, and it must be infinitely close to [-]%. "

Fang Bai's heart was also greatly relieved, although Fang Bai thought he did not have obsessive-compulsive disorder.

But seeing the messy frequency, the tin liquid containing impurities being adjusted uniformly and purified to the extreme, Fang Bai still couldn't help feeling a sense of satisfaction in his heart.

This is probably human instinct, lol.

"Through this method, it should be said that I can smelt and purify all ores or substances that can be melted and capture frequencies, and obtain high-purity elemental substances, right?

This is convenient. "

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

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

"No way, no way? You don't even record this method of purifying metals in the manuscript, do you?
That's great. "

Fang Bai muttered.

"Wait, wait, wait until I improve it a little bit."

Fang Bai didn't record it immediately, but set his sights on the tin liquid again.

Perceiving the pure frequency, Fang Bai's mental power engulfed a group of elements and forcibly changed its frequency through resonance.

"and many more."

Fang Bai suddenly realized a problem.

"How do I change the frequency of an element?"

"Forcibly change the frequency of the elements? The reason why my mental power can contact the elements is because the frequency of my mental power is the same as the frequency of the elemental power, and the resonance is achieved, so my mental power can capture the power of the elements.

Changing the elemental power of the spiritual power by myself will only cause the spiritual power to no longer be able to interfere with the elemental power.

Instead of causing the frequency of the power of the elements to change.

The way I capture the power of the elements, forcibly restrain it, and use spiritual power to resonate is just nonsense.

At present, there is one and only Wang Kai who has successfully changed the frequency of elements.

And how did he change? "

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

"The medium through which Wang Kai controls the power of elements is not spiritual power, but himself.

I only have mental power that can interfere with the power of elements, which is control.

And Wang Kai was born with the power of elements himself, and he can control his thoughts at the first movement, without the participation of spiritual power.

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

My control method is resonance, so I can't change the frequency of the elements, but Wang Kai can control it, and the power of the elements is his own power, so he can control the power of the elements to change the frequency at will.

This is the fundamental! "

In an instant, Fang Bai suddenly understood.

"So, Wang Kai still has to come, or"

"The knights still have to come."

Fang Bai seems to have discovered a new use for knights. Oh no, a new future.

If it is really possible to mass-produce elemental materials, then the knight profession will have a lot of money!

At this time Wang Kai was not around, he was busy, Fang Bai didn't call him in a hurry, but continued to sort out.

At the same time, a semi-closed furnace is formed by earth wall technique for use.

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

That thing is too technical, Fang Bai dares to use a blast furnace to blow it up!

Might never disappoints.
