(I couldn't stay up anymore and took a nap.) Sorry. ）

Zhang Hao had a confident smile on his face.

These tools are all made of 99.9% black iron, and they are completely aura-saturated steel. In the later stage, after a series of means such as folding and forging, carburizing, quenching, and tempering, its hardness has reached the peak of Zhangjia's temporary technical ability.

As the saying goes, if you want to do a good job, you must first sharpen your tools, Zhang Hao also struggled for a long time, and finally decided to make this 'super Xuantie' public.

Anyway, he has the identity protection of a disciple of the Xuanzhen Sect, and if he dies once in a while, he will be entertained~

Zhang Xinhan picked up the carving knife and didn't care much at first. But after an identification, his eyes widened.

At this time, there was already a gasping sound around him.

"99.9% Xuantie!" Zhou Xueyao was the first to speak. Originally, she was very conscious, although Zhang Hao gave herself a piece of 99.9% Xuantie, but she didn't tell others, including Zhou Jue. But at this time, I couldn't help but exclaim. She didn't expect that Zhang Hao would actually refine such a precious dark iron into a tool like this.

It's simply ...... Tyrannical Creatures!

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

Mei Qianyun and Fairy Mei of Yuxue Mountain Villa exclaimed: "Zhang Hao, you are really ...... Amazing!"

But Zhang Xinhan didn't speak at this time, he silently squatted down and carved on the steel pillar, but seeing that the dark iron pillar that was almost unshakable before, it could be portrayed relatively easily, although it was still a little difficult.

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

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

Yes, not black iron, not crude iron, but steel.

A new technology, but also a new material, but also the foundation of the road to the sea!

The dark iron pillars you see now, and the carving tools in your hands now, are all 'steel'.

Steel is developed on the basis of dark iron, which can promote the hardness of dark iron to the extreme, and even surpass the hardness of magic weapons.

And just like the dark iron, steel can continue to be processed into magic weapons, war weapons, and so on!"

At last the crowd grew brighter and more shocked.

This 'steel' was so extraordinary from the beginning, if it continues to be processed into magic weapons, war weapons, etc., how powerful can it be?

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

Will...... Create a legend?

At this moment, everyone's mood is eager to try!

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

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

Everyone looked at each other and exchanged glances, or secretly fought with each other.

Zhang Hao watched quietly, smiling. In fact, if he could, Zhang Hao would like to preside over this work himself. But Zhang Hao is very clear about his own ability.

The most important thing is that at the moment, whether it is Lu Yang or Zhang Xinhan, or the rest of the refining masters, they are all very arrogant. They're all fighting each other.

Professionals have a common problem -- civil and military affairs are the second, and martial arts are not the first! They all feel that they are not ambiguous.

Zhang Hao watched quietly, and after a while, Zhang Xinhan suddenly spoke: "I!"

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

In Xinglintang, I am in charge of almost all the refining tools. ”

The fellow door behind Zhang Xinhan immediately shouted: "This is our hall master's modesty, is it modest to understand! It's not like some people who know how to put gold leaf on their faces!"

Lu Yang's wife, Xiao Xiao, suddenly sneered: "Do you have the experience of being in charge of your own affairs? Can you preside over large-scale refining activities? How many people have you commanded to refine weapons?"

As soon as these words came out, the atmosphere went up, and there was tension for a while.

"Okay, okay!" Zhou Jue came out, as the young master of Xinglin Hall, as the senior disciple of the Jiuyang Sect, and as the chairman of the Refining Guild, Zhou Jue's identity is the most suitable and muddy, "No one can fight about this matter, the best way is to prove your ability with practical actions!"

The Dutian Fire Array needs 12 foundations, but there are 14 steel pillars here, so I think it's just right to use two steel pillars to practice and test the abilities of both sides by the way.

How?"

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

Zhou Jue looked at Zhang Hao again: "What does the younger brother think?"

"Absolutely. But let's use these two steel columns first, these two were the first to be produced, relatively speaking, the technology is still slightly insufficient. ”

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

Zhou Jue nodded, and asked again: "Brother Shi, if you want to make a magic weapon, you still need a little other spiritual material, whether it is red copper, mythril or pure gold, you need a little." Moreover, to make such a huge magic weapon, it is estimated that the rest of the spiritual materials will cost at least a thousand catties. ”

"Nope. Zhang Hao said very directly, "But I think Brother Zhou must have it." I am willing to replace it with 99.9% blacksteel. ”

"Haha......" Zhou Jue laughed excitedly.

Suddenly, Feng Zhiling appeared again, he held two large pieces of pure gold in both hands, and threw them in front of Zhang Hao: "Brother Shi, a total of two thousand catties of pure gold, I don't want much, exchange for two hundred catties of 99.9% Xuantie." ”

Zhou Jue: ...... You're the only one to be missing!

Zhang Hao, but he was overjoyed, Senior Brother Feng didn't have cramps this time, this was telling himself the price. The price of 99.9% dark iron is ten times the price of pure gold!

Zhang Hao said directly: "Senior brother, thank you." In the case of dark iron, it takes fifteen days to prepare. ”

After speaking, he smiled embarrassedly at Zhou Jue: "Brother Zhou, this is ...... It takes a little time to refine 99.9% of the black iron. How about we talk about it in half a month?"

Zhou Jue's complexion changed a few times, his teeth creaked, and he finally had to nod. Looking at Zhang Hao's appearance, it is very difficult to smelt this ultra-high purity dark iron.

It's just that Zhou Jue didn't know that the Zhang family had already produced high-purity dark iron. But Zhang Hao hid a hand!

In short, the pure gold was there, Lu Yang and Zhang Xinhan glanced at each other, snorted coldly, turned their heads to the side, and each received a hundred catties of pure gold and got busy.

The seal carving formation is not simple, after the seal carving pattern, it is necessary to use real fire to melt the pure gold and spread it on the formation pattern, and it must continue to heat until the pure gold penetrates into the inside of the dark iron.

And in this process, it is also necessary to explore the aura flow of Xuantie itself.

The high-purity dark iron can naturally absorb a little spiritual energy, and there is a little weak 'spiritual vein', although this spiritual vein can almost be ignored, if the formation can be combined with this spiritual vein, it can increase the power of the magic weapon by several percent.

And this is enough to become the key to the victory or defeat of the two!
