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 Xuan Tie, and the molds were very crude. The products of casting are mainly thick iron plates, thick-backed broadswords, hammers, chisels and other relatively crude things. These materials are marked 'Class 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 is still rolling, and there are no more 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 cooled quickly, and the thick spiritual energy suddenly became extremely viscous and colorful lights flowed.
Zhang Hao suddenly felt refreshed. Taking a deep breath, I felt that the spiritual energy was more active than ever before. After taking a breath, I could feel the progress of my cultivation.
"Thisthisif 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, and they still need elixirs. .
Cultivation requires enlightenment, and the barriers 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 pills such as Peiyuan Pill and other pills that assist in practice." Just creating such an environment would 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 spiritual energy in a small area, we may be able to 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, they will study and arrange a practice space like this."
"Okay." Zhang Hao nodded.
The spiritual energy within the barrier gradually dissipated, the temperature also dropped, and the molten iron inside the barrier was also seen melting. Huang Mingshan and others were busy again. Although they knew that this place should have failed, they were still busy meticulously. However, these materials were labeled as ¡®B-grade¡¯.
After that, it was just a matter of waiting, waiting for the black iron to cool down.
Some dark iron cools naturally; some solidifies slightly and is taken out for forging; some is directly quenched.
Zhang Hao is waiting here, but Huang Mingshan and others are busy without touching the ground. Although they had not slept all night, everyone was in high spirits.
By the afternoon, 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 materials is to destroy them!
Huang Mingshan and others first took down the precious magic weapon sword and poked all the items, 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 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 slipped away little by little, and when Huang Mingshan poked the naturally cooled first-class item with a medium-grade magic weapon, a dent finally appeared. But those that were forged and tempered remained motionless.
It was not until Huang Mingshan poked it with a high-grade magic weapon that he finally left a faint trace on the final first-class material; and the tip of the sword almost broke.
"What a hard black iron!" Zhang Shengde was amazed and stepped forward to evaluate it. But he soon frowned. "It's quenched and integrated, and the true essence can't penetrate it."There are those that are naturally cooled and forged, which can penetrate the spiritual energy. The purity is between 85% and 86%. "
"I'll give it a try!" Zhang Shengye came to a quenched iron plate, took out his flying sword, and was about to attack.
"Second uncle, don't use your flying sword, it will break!"
Zhang Shengye was stunned for a moment, then followed his example, 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 is clanging and sparks are flying. Zhang Shengye's golden elixir level power and sharp magic weapon couldn't pierce the iron plate.
Zhang Shengye kept moving, and suddenly there was a clang, and the flying sword in his hand broke. On the iron plate, there was only a small hole no more than an inch deep.
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 with a clanging sound. The rocks on the ground were broken, but the iron plate was only slightly dented.
Zhang Shengye continued to go 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 so, and he was still excited. He said excitedly: "Dad, we succeeded. We also obtained materials of top magic weapon quality without using strange fire. 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-level 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!"
He then 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 Master 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 others be impressed."
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. (Remember the website address: www.hlnovel.com
