In fact, Zhang Hao has some guesses about Xuan Tie:
Isotopes!
Black iron and iron exist in the form of iron oxide and other forms in ores. Therefore, during the ore screening process, it is impossible to distinguish black iron and iron.
During the smelting process, charcoal is needed for reduction. In an environment without spiritual energy, they can all be oxidized into rust and become indistinguishable from each other.
In addition, magnetism and some chemical properties are basically the same.
What is commendable is that the density of the best black iron purified by the Zhang family, that is, 99.9% black iron, is about one-fiftieth more than that of crude iron!
All of this seems to point to the isotope of iron: iron 57!
Of course, the molecular weight of 57 is based on the standards of another world; anyway, Zhang Hao remembered it from the textbook that the usual molecular weight of iron is 56, and there are isotopes such as iron 54 and iron 57 in nature.
And the ¡®Xuantie¡¯ here is just a little heavier, most likely it is Iron 57.
Iron 57 has one more neutron than iron 56!
In other worlds, it is said that ¡®neutrons¡¯ have no attributes; most scientific research is conducted around electrons and protons.
Maybe it¡¯s not that neutrons have no attributes, it¡¯s just that in another world without aura, neutrons are redundant. But with the aura in this world, the importance of neutrons is revealed!
Zhang Hao returned to his room, took out a notebook, and began to write and draw:
If this conjecture is correct, then Zhang Hao also has some speculation about the nature and function of strange fire and real fire - to stimulate the spiritual energy and let neutrons capture the spiritual energy!
If you want to verify this idea, it is relatively simple in principle. According to ordinary observations, if you want to 'stimulate spiritual energy', the temperature of ordinary flames is far from enough, so you have to use strange fire or real fire.
And if you want to get high temperature, the easiest way is ¡®high pressure¡¯. The representative product is: pressure cooker.
Of course, if you want to get a temperature far beyond that of an ordinary flame, the pressure will be extraordinary.
Based on normal smelting data, this temperature must exceed, or even far exceed, two thousand degrees. And more than two thousand degrees is enough to melt Xuan Tie.
So, this requires looking for tungsten ore or graphite. But considering the current weak technology of the Zhang family, graphite is the first choice.
NoWait a minute, this is a world of cultivation, there are formations! I don¡¯t know if the formation can meet the requirements?
After lunch, Zhang Hao found his father and asked about the formation.
"A formation that is airtight, can withstand high temperature, high pressure, and is large enough?" Zhang Shengde thought for a moment and said, "There are such formations. The formation that seals the earth fire in our smelting base should be .
That formation is called yes, it's called the Trapped Dragon Formation, yes, it's called the Trapped Dragon Formation. "
"Dad, you can't even name our formation?"
"You bastard!" Zhang Shengde slapped Zhang Hao on the head, but with no force. "That formation was helped by someone else. How can I remember it clearly? By the way, your uncle arranged that formation."
"What about my uncle?" Zhang Hao was very curious. He had never seen his mother's side before. It seemed as if he had evaporated out of thin air. Isn't there some bloody plot?
Zhang Shengde's expression was a bit strange: "Your uncle I can't comment. The last time I saw him was more than 20 years ago. He is a master of formations, and his cultivation has reached the peak of the Golden Core stage.
But he likes to travel around, saying that he wants to look for opportunities to break through to the Nascent Soul stage. Your mother was left behind, and after setting up the formation, she drifted away.
So far there has been no news. "
Zhang Hao suddenly frowned, feeling another very unreliable guy!
"Your mother has cried several times over the years. But the world is so vast, where can I look for it? Alas"
"What about my grandma and grandpa?"
"When I met your mother, it was just your mother and your uncle. Your mother was just 16 years old at that time."
¡¡¡¡
In the afternoon, Zhang Hao came to the conference room of the Weapon Refining Guild.
Zhou Jue greeted Zhang Hao enthusiastically, "Brother Shi, sit here."
The position where Zhou Jue asked Zhang Hao to sit was actually the position of vice chairman. Originally, the vice chairman was Zhang Shengye, but Zhang Shengye was injured and not in a good mood, so he was absent.
Zhang Hao greeted everyone. Compared to the Black Iron Guild, the atmosphere of the Weapon Refining Guild was more harmonious.
No, Zhang Hao hasn¡¯t sat down yet, Mei Qianyun chuckled and said:?Zhang Hao, just now Zhou Jue said that you have the habit of sleeping in? "
There was good-natured laughter all around.
Zhang Hao sat down with a dark face and a dejected look on his face, but he saw a piece of irregular silver-white metal the size of a child's fist placed in front of Zhou Jue. The metal was slightly yellowish-white, with a spiritual light hovering on the surface, and the aura was slightly deep. .
"This isstar gold?"
Zhou Jue nodded: "It was sent by the imperial guard, a little over 25 kilograms. This thing is almost three times as heavy as Xuantie."
"Can I have a look?"
Zhou Jue nodded. Zhang Hao took it over and tried it, and used his immature identification skills to make an identification. The metal was the size of a child's fist, but it weighed 25 kilograms. It was roughly estimated that the density was almost 3.5 times that of black iron.
Zhang Hao narrowed his eyes: The metal from space has a density almost 3.5 times that of iron and exists in the form of a simple substance. Couldn't this be iridium?
And remember that on the periodic table, iridium seems to have a molecular weight of 192 and an atomic number of 77. In other words, iridium has 115 neutrons, and the number of neutrons far exceeds that of protons!
If this thing is really iridium, then Zhang Hao can conclude that there must be a relationship between aura and neutrons.
Zhang Hao calmly put down the star gold and expressed his admiration.
After a while, several more people arrived, and Zhou Jue clapped his hands: "The meeting has begun. Today we are going to discuss the management model, identify various departments and responsible persons, and new production methods."
The meeting lasted until the evening, especially when it came to new production methods, division of labor, streamlined operations and other issues, Zhang Hao showed off a little bit.
At the end of the meeting, Zhang Hao suddenly stood up and said, "Wait a moment, everyone, I want to purchase a set of formation flags or formation plates for the trapped dragon formation. The kind that can withstand high temperature, high pressure, and is airtight."
Mei Qianyun was the first to speak: "What you want is a formation that can withstand high temperature, high pressure, and airtightness, right?"
"right."
"We at Yuxue Villa have a set of 'Mountain Binding Formation'. The complete Mountain Binding Formation can even seal the volcano."
Zhang Hao was overjoyed: "Here's a set! Just a simple one."
Mei Qianyun immediately laughed: "A simple mountain-binding formation requires a ton of black iron specially used for alchemy!"
Zhang Hao's face suddenly turned dark: "Fairy Mei, we are all acquaintances, so give us a real price. You offer the spirit stone, and I will give you black iron at a discount."
Mei Qianyun smiled proudly: "Zhang Hao, do you know how complicated a mountain-binding formation is? Even a simple one has one hundred and eight formation flags. It's enough to suffocate the Zhang family and trap the Nascent Soul Stage!"
Zhang Hao¡¯s eyes lit up: Ha, have you thought of this? Well, Zhang Hao agreed and asked for the instruction manual - a jade slip.
"Tomorrow, the formation flag will be delivered. The Zhang family must prepare black iron."
"Xuan Tie needs some time. How about ten days?"
"good!"
As soon as Mei Qianyun finished speaking, Mu Yingying immediately jumped in and said, "We have a complete trapped dragon array at home, and the effect is very good. Just one thousand high-grade spiritual stones are enough."
"I want two sets! We will pay with black iron specially used for alchemy." Zhang Hao said loudly.
"Okay!" It was Mu Mingchen who answered.
Zhou Jue finally had a chance: "Brother Shi, our Jiuyang Sect has a more powerful 'Trapped Immortal Formation', which is similar to the Trapped Dragon Formation, but several times more powerful."
"Then another set! Also pay with black iron specially used for alchemy."
Zhou Jue said unceremoniously: ¡°I want a ton.¡±
"Okay." Zhang Hao said simply, "But isn't the price a bit high?"
¡°Don¡¯t worry Shidi, if you find that the price is too high in the future, we will refund it in full!¡±
Zhang Hao smiled and turned to look at everyone: "Whoever has a similar formation is welcome to provide it. The Zhang family will all pay with black iron specially used for alchemy. Pay the cost price, just this time!"
"Master Zhang, we have a 'Zhou Tian Demon Sealing Formation'."
"We have the 'Great Zhou Tian Demon Sealing Array' and the 'Eight Directions Demon Refining Array'."
