Fang Bai glanced around and instantly locked his target on a piece of iron.
"Iron, or metal!"
"The metal has high purity, simple internal structure, and can be "destructed" by melting.
After melting, it solidifies again and becomes a metal block again."
"However, pig iron is actually an iron-carbon alloy, and the carbon content of steel is only about 0.03 to 2 percent.
The melting point of steel is relatively high."
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 200 degrees, and it melts easily.
Fang Bai lit a fire, then cut the tin into pieces and put them into the crucible.
As the crucible is heated, the metallic tin inside is gradually melted and turned into a small pot of silver-white liquid.
Fang Bai repeated his old trick, using his mental power to sense the frequency of the liquid.
Even in the liquid state, metal has a very low frequency, is very stable, and is difficult to capture. It is no different from before.
It took Fang Bai a lot of effort to capture its frequency. When he sensed the frequency, Fang Bai's eyes lit up with joy.
"Sure enough, the frequency of the melted metallic tin was unified.
Although there are still some messy frequencies, they should be the frequencies emitted by the magazines inside, and they are within the acceptable range and 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 a minute, if it is said that my mental power can communicate with and interfere with it in the same frequency state, but it can pass through directly in the different frequency state, then."
Fang Bai felt as if he had discovered a gua, a gua that belonged to all mages and all spiritual people.
"Does this mean that as long as I resonate, I can completely filter out all the impurities in the tin?"
"Does this mean that as long as I want, I can extract the elements of any metal and obtain 100% pure metal that has never been seen in history?"
Fang Bai was slightly startled, and immediately gave up capturing the main frequency of the tin liquid, and instead went directly to capture those messy and tiny frequencies.
Sensing one of them, Fang Bai's mental power instantly synchronized with it.
Then Fang Bai used his mental power to form a surface and used this surface to pull it through the tin liquid.
The airtight surface passes directly through the tin liquid without causing any ripples in the tin liquid, as if it exists in two different parallel worlds.
And when this mental power touches the impurities in it, it is directly captured by the mental power, and then is carried away from the tin liquid.
Fang Bai used his mental power to sense the negligible impurities, threw them away, and transformed his mental power into the next frequency again, filtering it again.
Time after time, time after time, each time the tin liquid is filtered, the frequency of chaos in the tin liquid is reduced by one, and each time the tin liquid is filtered, the purity of the tin liquid is improved a little bit.
Finally, when Fang Bai did not capture any messy frequencies in the tin liquid, the frequencies on the entire tin liquid were unified, and there was only one frequency!
Fang Bai felt the complete frequency, and a sense of satisfaction immediately surged in his heart.
"It would definitely be very comfortable for an obsessive-compulsive disorder to do this job. If an obsessive-compulsive disorder became a mage, and let him master the method of sensing frequencies."
Fang Bai muttered.
"Then all alloys or metals with impurities he has seen will be purified into simple substances by him."
Fang Bai thought with a smile.
"One hundred percent pure tin, at least in the fields that my current mental power can involve, I can guarantee that it is one hundred percent pure.
And on a practical level, even if it doesn't reach 100%, it's definitely quite pure, and it's definitely close to 100%."
Fang Bai felt very happy, even though Fang Bai thought he did not have obsessive-compulsive disorder.
But seeing the chaotic frequency, the tin liquid containing impurities being adjusted uniformly and purified to the extreme, Fang Bai could not help but feel a sense of satisfaction in his heart.
This is probably human instinct, laugh.
"Through this method, it should be said that everything can be melted, and I can smelt and purify any ore or substance that can capture the frequency, and obtain high-purity elements, right?
It’s more convenient now.”
Fang Bai said comfortably, and then recorded this technique in his notebook.
But at this moment, the manuscript in my mind opened again and a pen condensed.
"No, right? You don't even record this method of purifying metals in the manuscript, do you?
So cool."
Fang Bai muttered.
"Wait, wait, wait until I perfect it a little bit."
Fang Bai did not record it immediately, but instead focused on the tin liquid again.
Perceiving the pure frequency, Fang Bai's mental power enveloped a group of elements and forcibly changed their frequency through resonance.
"etc."
Fang Bai suddenly realized a problem.
"How do I change the frequency of an element?"
"Forcibly changing 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. The resonance is achieved, so my mental power can capture the power of the element.
Changing the elemental power of my mental power by myself will only result in the mental power no longer being able to interfere with the elemental power.
Rather than causing the frequency of elemental power to change.
My method of capturing the power of the elements, forcibly restraining them, and using my mental power to resonate is just nonsense.
At present, only Wang Kai has successfully changed the frequency of elements.
And how did he change?"
Fang Bai thought quietly, and the answer quickly appeared in his mind.
"The medium through which Wang Kai controls the power of elements is not mental power, but himself.
My only mental power that can interfere with the power of the elements is control.
Wang Kai, on the other hand, gave birth to the power of the elements himself, and could control his thoughts at a moment's notice 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 the elements, but Wang Kai can control it originally. 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 fundamental!”
For a moment, Fang Bai suddenly became enlightened.
"So, Wang Kai still has to come, or rather"
"The knight still needs to come."
Fang Bai seems to have discovered a new use for knights. Oh no, a new future.
If elemental materials can really be produced in batches, then the knight profession will have endless money!
Wang Kai was not around at this time, he was busy, and Fang Bai did not call him in a hurry, but continued to comb.
At the same time, earth wall techniques were used to create a semi-enclosed furnace for use.
Of course, it is just a furnace shell, not a real steelmaking blast furnace.
The technical content of that thing is so high that if Fang Bai dared to use a blast furnace to blow it up!
