The barrier opened, crazy high temperatures rushed out, and the soil on the nearby ground quickly turned black.
Huang Mingshan and others wore armor and rushed in without hesitation. They directly used thick shovels to transfer the molten iron suspended on the barrier into a simple mold.
This time it was just to verify the processing results of black iron, and the molds were very crude. The cast products were mainly thick iron plates, thick-backed broadswords, hammers, chisels and other relatively crude things. These materials were marked as 'Grade A'.
Huang Mingshan and others finished their work and retreated, waiting for the black iron to cool down.
In the barrier next to it, the spiritual energy was still rolling, without any further changes. As time went by, the spiritual energy gradually seeped out of the barrier and dissipated little by little.
Zhang Hao thought thoughtfully: "It seems that the barrier cannot completely isolate the spiritual energy. After it exceeds a certain level, it will gradually dissipate. Huang Mingshan, open a corner of the formation to disperse the spiritual energy."
The spiritual energy of more than five million spiritual stones seems to be wasted.
But when the hot and rolling spiritual energy rushed out, the spiritual energy quickly cooled, and the thick spiritual energy suddenly became extremely viscous, and colorful lights flowed.
Zhang Hao suddenly felt refreshed. He took a deep breath, but felt that the spiritual energy was more active than ever before. After taking a breath, he could faintly feel the progress of his cultivation.
"This...this...if I practice in such an environment, I can reach the Nascent Soul stage within a year! And I won't even need pills!" Zhang Shengye was a little incoherent.
Zhang Shengde was relatively calm. He felt it carefully and shook his head: "It's not that simple. I think those who live in the Paradise of Cave Heaven can enjoy such practice every day, but they may not all achieve Nascent Soul. They still need elixirs.
.
Cultivation requires meditation, and the checkpoints and bottlenecks in the body also need to be cleared with the help of elixirs. Some medicinal properties cannot be replaced by spiritual energy.
However... it should be able to replace elixirs such as Peiyuan Dan and other elixirs that assist cultivation. Just creating such an environment will be more expensive than elixirs!"
"Uh..." Zhang Shengye chuckled and stopped talking.
Zhang Hao looked at the rolling spiritual energy and had some thoughts: "Dad, if we can restrain this kind of spiritual energy in a small area, maybe we can create a blessed place and promote the rapid growth of the family.
Nowadays, elixirs are in short supply and trade routes are blocked. Since there is a way to reduce the demand for elixirs, we should try it."
Zhang Shengde thought for a moment and nodded immediately. "When Huang Mingshan and the others have some free time, we will study and arrange a practice space like this."
"Okay." Zhang Hao nodded.
The spiritual energy in the barrier gradually dissipated, the temperature also dropped, and the molten iron in the barrier was also seen. Huang Mingshan and others were busy again. Although they knew that this place should have failed, they were still busy meticulously. However,
Mark these materials as 'Class B'.
After that, it was just a matter of waiting, waiting for the black iron to cool down.
Some black iron cools naturally; some solidifies slightly and is taken out for forging; some is directly quenched.
Zhang Hao was waiting here, while Huang Mingshan and others were busy without touching the ground. Although they had not slept all night, everyone was in high spirits.
It was not until the afternoon that all the black iron was finally processed.
This time, a total of about two tons of black iron were used for the experiment, and a variety of black iron with different purity were used; however, during the experiment, all the black iron was melted together.
After cooling, Huang Mingshan and others began to experiment. The most direct way to test the material is to destroy it!
Huang Mingshan and others first took the high-quality magic weapon sword and poked all the items again, making endless clanging sounds; the efficiency was very fast. A batch of naturally cooled second-grade iron plates, items, etc. were eliminated.
And the sword that stabbed the first-class object unexpectedly curled its blade or broke.
Zhang Hao's eyes brightened - although it was only the first test, Zhang Hao had already seen success.
Huang Mingshan and others were meticulous and switched to medium-grade instruments to continue poking; another batch of second-grade ones were eliminated; the first-grade ones were still safe and sound.
Then put on a high-grade magic weapon and continue poking, poking, poking...
Time flew by little by little, and when Huang Mingshan poked the naturally cooled Class A items with a medium-grade magic weapon, dents finally appeared. But those forged and quenched items remained motionless.
It wasn't until Huang Mingshan used a high-grade magic weapon to poke it that he finally left faint traces on the final first-class material; and the sword tip almost broke.
"What a hard black iron!" Zhang Shengde was amazed and stepped forward to examine it. But he soon frowned. "The quenched iron is so integrated that the real energy cannot penetrate. Only the naturally cooled and forged iron can penetrate the spiritual energy.
The purity is between 85% and 86%.”
"Let me give it a try!" Zhang Shengye came to a piece of tempered iron plate, held out his flying sword, and was about to attack.
"Second uncle, don't use your flying sword, or it will break!"
Zhang Shengye was stunned for a moment, then he followed Shan Ruliu, picked up a worn-out magic flying sword from the side, and chopped it hard on a three-inch-thick tempered iron plate.
The iron plate was clanging, and sparks were flying. Zhang Shengye's golden elixir-level power, coupled with the sharp magic weapon, was unable to pierce the iron plate.
Zhang Shengye kept moving, but suddenly with a clang, the flying sword in his hand broke. And there was only a small hole of less than an inch left on the iron plate.
Zhang Shengye picked up the hammer. This hammer had just been cast with Grade A black iron.
A hammer hit the spot where it was just now, and the iron plate trembled continuously. The rocks on the ground were broken, but the iron plate was only slightly dented.
Zhang Shengye continued to be crazy, and the rocks were shattered; tiny cracks gradually appeared on the iron plate.
Zhang Shengye took a deep breath, stood up straight, picked up the hammer again, and smashed it down.
With a loud bang, the steel plate was completely shattered, like ordinary glass.
"Quenched, it is very likely to form a 'vitreous body'." Zhang Hao thought, still excited in his heart, and said excitedly: "Dad, we succeeded, without using strange fire, we also obtained materials of top magic weapon quality.
And it's a big piece of iron plate.
Once we figure out the rules, we should be able to build a real, indestructible ship! A top-notch magic weapon-level ship made entirely of black iron!
We succeeded!"
Zhang Shengde was also excited: "Yes, we succeeded, we succeeded! Rewards, lots of rewards!"
Then he turned to look at Zhang Hao: "I think we should give this new type of black iron a new name."
"Let's call it 'steel'." There was a flash of light in Mr. Zhang's eyes, "The so-called steel means strong and unyielding. Look at this steel plate. In the end, it would rather break than bend."
Zhang Shengde looked at the broken 'steel' and nodded slowly: "Okay, let's call it 'steel'."
"It's steel." Zhang Hao wrote the word "steel" on the ground. "This is a new material. We should also create a new word. Only in this way can we impress others."
Zhang Shengde smiled: "Okay, okay, Steel, Steel. Huang Mingshan, you have been busy all day, go back and rest first."
"Thank you, Master, but there are still experiments to be done. Rest after you finish."
Huang Mingshan led everyone to continue to classify all the materials in detail and record various data. Scientific research requires seriousness, rigor and responsibility.
