(I couldn’t stand it any longer and took a nap. Sorry.)

Zhang Hao had a confident smile on his face.

These tools are all made of "steel" made of 99.9% black iron, and are completely spiritually saturated steel. Later, they were folded and forged, carburized, quenched, tempered and other methods, and their hardness has reached tens of billions.

The pinnacle of home's temporary technical capabilities.

As the saying goes, if you want to do your job well, you must first sharpen your tools. Zhang Hao struggled for a long time and finally decided to reveal this 'super black iron'.

Anyway, I have the protection of being a disciple of the Xuanzhen Sect, so I only try to commit suicide once in a while, just for fun~

Zhang Xinhan picked up the carving knife and didn't pay much attention to it at first. But after the identification technique, his eyes widened.

At this time, there was a sound of gasping for air all around.

"99.9% black iron!" Zhou Xueyao was the first to speak. She was very conscious at first. Although Zhang Hao gave her a piece of 99.9% black iron, he didn't tell anyone else, including Zhou Jue. But at this time, she couldn't help being surprised.

Phew. She didn't expect that Zhang Hao would refine such precious black iron into tools.

This is simply...a waste of natural resources!

Yes, Zhou Xueyao's exclamation was not only surprising, but also vaguely angry.

Fairy Mei Qian Yunmei of Yuxue Villa exclaimed: "Zhang Hao, you are really... surprising!"

Zhang Xinhan did not speak at this time. He squatted down silently and carved on the steel pillar. However, he saw that the black iron pillar that was almost unshakable before could be carved relatively easily, although it was still a bit difficult.

Zhang Xinhan stood up and looked at the tools on the plates of Huang Mingshan and others, his eyes full of shock.

Zhang Hao picked up a tool and raised it high, attracting everyone's attention. Zhang Hao said loudly: "I would like to solemnly introduce to you the latest technology of the Zhang family - steel technology!

That's right, it's not dark iron or thick iron, but steel.

A brand-new technology, a brand-new material, and the foundation for opening up a road to the sea!

The dark iron pillars you see now and the carving tools you have in your hands are all ‘steel’.

Steel is developed on the basis of dark iron. It can push the hardness of dark iron to the extreme, even surpassing the hardness of magic weapons.

And just like black iron, steel can continue to be processed into magic weapons, war weapons, etc.!"

Everyone finally became brighter and more shocked.

This 'steel' is so extraordinary from the beginning. If it continues to be processed into magic weapons, war weapons, etc., to what extent can its power be exerted?

At this time, everyone looked at the 14 'steel pillars' behind them again, and their eyes were different: There are 14 steel pillars here now. If they can be upgraded into magic weapons or top-notch magic weapons, what kind of power will they create?

Will it...create a legend?

At this moment, everyone was in an excited mood!

Zhang Hao shouted again: "Everyone, the Zhang family is not proficient in weapon refining. So... I wonder who is willing to be the overall person in charge of this weapon refining?"

Zhang Hao's turn was a little big. Everyone was stunned for a while, but soon became excited. This is an opportunity! If you can take charge of this work, the rewards will be unimaginable!

Everyone looked at each other and communicated with their eyes, or secretly fought.

Zhang Hao watched quietly with a smile. In fact, if possible, Zhang Hao would like to take charge of this work himself. But Zhang Hao knows his own abilities very well.

The most important thing is that now, whether it is Lu Yang, Zhang Xinhan, or the other masters of weapon refining, all of them are very arrogant. They are all competing with each other.

Professionals all have a common problem - they are second in civil and military, but not first in martial arts! They all feel that they are unambiguous.

Zhang Hao watched quietly for a while, and then Zhang Xinhan suddenly said: "Me!"

Lu Yang smiled coldly: "I remember someone just said that I still need to study more. I think I can do it.

In Xinglin Hall, I am responsible for almost all the weapon refining."

The fellow students behind Zhang Xinhan immediately shouted: "This is the modesty of our hall master. Do you understand modesty? It's not like some people who just know how to put gold foil on their faces!"

Lu Yang's wife Xiao Xiao suddenly sneered: "Do you have any experience on your own? Have you ever hosted a large-scale weapon refining event? How many people have you directed to refining weapons?"

As soon as these words came out, the atmosphere became tense and tense.

"Okay, okay!" Zhou Jue came out. As the young master of Xinglin Hall, as the head disciple of Jiuyang Sect, and as the chairman of the Weapon Refining Guild, Zhou Jue's identity is the most suitable for He Xini, "No one can do this.

Stop arguing, the best way is to prove your ability with actual actions!

The Dutian Fiery Formation requires 12 foundations, but there are 14 steel pillars here. I want to practice with just two steel pillars and test the abilities of both parties.

how?"

"Okay!" Lu Yang and Zhang Xinhan said in unison.

Zhou Jue looked at Zhang Hao again: "What do you think, brother Shi?"

"Of course. But let's use these two steel columns first. The two steel columns that were produced first are relatively lacking in technology."

The two steel pillars Zhang Hao pointed to were marked with red paint.

Zhou Jue nodded and asked again: "Brother, if you want to make a magic weapon, you need some other spiritual materials. Whether it is red copper, mithril or fine gold, you need some. And to make such a huge magic weapon, it is expected that other spiritual materials will be needed."

The material must be at least 1,000 kilograms."

"No." Zhang Hao said very directly, "But I think Brother Zhou must have it. I am willing to replace it with 99.9% black iron."

"Haha..." Zhou Jue laughed excitedly.

Suddenly, Feng Zhiling appeared again. He held two large pieces of fine gold in both hands and threw them in front of Zhang Hao: "Brother Shi, there are two thousand kilograms of fine gold in total. I don't want much. I want to exchange it for two hundred kilograms of 99.9% black iron.

."

Zhou Jue:...You are indispensable everywhere!

As for Zhang Hao, he was overjoyed. Brother Feng didn't have cramps this time. This was telling him the price. The price of 99.9% black iron is ten times the price of fine gold!

Zhang Hao said directly: "Senior brother, thank you. For Xuan Tie, it will take fifteen days to prepare."

After saying that, he smiled sheepishly at Zhou Jue and said: "Brother Zhou, this... refining 99.9% of the black iron will take a while. How about we talk about it in half a month?"

Zhou Jue's expression changed several times, his teeth gritted loudly, and finally he had to nod his head. Judging from Zhang Hao's appearance, it was very difficult to smelt this ultra-high-purity black iron.

But Zhou Jue didn’t know that the Zhang family was already capable of producing high-purity black iron. But Zhang Hao had a hidden secret!

In short, the fine gold was there. Lu Yang and Zhang Xinhan looked at each other, snorted again, turned their heads aside, and each received a hundred kilograms of fine gold and got busy.

The seal carving formation method is not simple. After the seal carving formation pattern is carved, the fine gold must be melted with real fire and spread on the formation pattern, and the heating must be continued until the fine gold penetrates into the black iron.

Moreover, in this process, we also need to explore the flow of spiritual energy of Xuan Tie itself.

High-purity black iron can naturally absorb a little spiritual energy and have a weak 'spiritual vein'; although this spiritual vein can be almost ignored, if the formation can be combined with this spiritual vein, the power of the magic weapon can be increased by several times.
