(Bill: 22 more)

Facing Zhang Hao's inquiry, Zhou Jue thought for a while and said: "The special dark iron for alchemy, inside the country of Qixia, should be at least 80 tons per year. In the whole of the six Western countries, it is no less than 350 tons per year. ”

Zhang Hao was silent for a long time, and suddenly spoke: "In the future, the special dark iron for alchemy in Western countries will be provided by our Zhang family." Price...... Price......"

Zhou Jue's ears pricked up.

I don't want Zhang Hao to suddenly have a divine turn: "By the way, what is the price of the special Xuantie for alchemy in the country of Canglan?"

Zhou Jue almost bit his tongue, I waited for a long time, and you actually asked me this. But after thinking about it, he said, "Not sure." It is said that twenty or thirty high-grade spirit stones. ”

Zhang Hao nodded: "Then, the price of the Zhang family is: 99.0% purity, 15 high-grade spirit stones per catty! For every 0.1 increase in purity, the price increases by 2 high-grade spirit stones." ”

Zhou Jue was overjoyed, but he had a sad face on the surface: No matter how cheap it is, this price is still too expensive.

The two theorized for a long time, and Zhang Hao dropped to 10 commercial spirit stones.

Zhou Jue bowed to Zhang Hao in the end.

Zhang Hao accepted it calmly. Although the cost of smelting this kind of high-purity dark iron is not high, the technology is valuable! The most important thing is to break the monopoly of the East and stop the outflow of spirit stones, which is of great significance.

We are self-sufficient and can export!

Then, Zhang Hao put forward his two requirements:

The first is the price of Xuantie, which is only the price within the country of Qixia, and it is slightly more expensive to sell it to the rest of the five western countries, and it must be limited.

If the limit is exceeded and sold to the East, the price must be increased, but it must be cheaper than that from Kunlun Continent.

How to control this price, Zhou Jue needs to help - everyone has money to earn together, Zhang Hao knows very well that the Zhang family's own strength is a little weak.

Second, Zhang Hao is very yearning for the kind of identification that can identify the decimal point. The princess had shown that powerful identification technique before, but Zhang Hao was embarrassed to speak;

Zhou Jue was also very simple, and the appraisal technique was directly given to Zhang Hao, and for the price, he said that he would go back and discuss it with the master of the Jiuyang Sect and even his father Zhou Shuhai. It's expected to take 10 days.

Zhou Jue was about to leave in a hurry after speaking, but Zhang Hao shouted: "Brother Shi, wait, the younger brother still has a question." ”

"What's the matter?" Zhou Jue's figure continued to float towards the sky, his robe sleeves fluttering, like a person in the clouds.

"I want to ask, why is it that the purity of Xuantie Iron reaches more than 99%, and it can refine spiritual weapons, what is the reason?"

"You take this. Zhou Jue hurriedly threw out a jade slip, flew above the white clouds with a swish, and disappeared with another swish.

Zhang Hao took the jade slip and looked at the sky speechless~~~

Regarding the question of the spirit weapon, Zhang Hao has been entangled for a long time, but the people around him can't give Zhang Hao an answer. Knowledge is in the hands of a few.

The jade slip is very rich in content, and even contains some refining methods for spiritual weapons.

"So generous......"

"Hula......" There was a sound of wind overhead, and he saw Zhou Jue going and returning, and he shouted on the roof: "Don't lose that jade Jane, come back and give it to me." ”

With that, he snorted again and flew away.

Zhang Hao: ......

Image, image, you have thrown the image of the eldest disciple of the Jiuyang Sect and the young master of the Zhou family into the ditch.

After watching Zhou Jue's figure disappear completely, Zhang Haocai continued to watch Yu Jian and found the information he needed.

It turns out that the higher the purity of the dark iron, the stronger the ability to transmit to the aura, and as the conduction ability increases, it will show some peculiar properties.

Especially when the purity of the dark iron is as high as more than 99%, the aura is almost unimpeded, and it can perfectly withstand the master's true yuan, spells, supernatural powers, etc., and has a certain ability to gather aura.

"To put it bluntly, it's a superconductor! It's a little bit of magnetism~~~"

"As for the identification...... True Yuan and Spiritual Consciousness are needed, and the Qi Refining Period only has True Qi; Spiritual Consciousness is a little, but it is not enough. ”

Zhang Hao reluctantly put down the jade slip of the appraisal technique, and prepared to hand it over to his father, second uncle, eldest brother, etc.

Well, now that my father and second uncle are still cultivating, I can only trouble Zhang Han for the time being.

It took Zhang Han more than two hours to master the new identification technique and began to participate in new research - ultra-high purity dark iron.

Huang Mingshan and the others were extremely serious, and they all seemed to have a sense of mission on their faces.

Zhang Han's curiosity from the sidelines, the new smelting method, made him unable to understand.

"Why is this iron powder separated from charcoal powder, and how do they react?"

"Why is there only a little air?"

"In the process of smelting dark iron, shouldn't spirit stone powder be added?"

......

Zhang Hao had a black line, but Huang Mingshan explained excitedly.

As a result, there are more problems.

"Oxygen? What kind of gas is this?"

"Am I getting rust in my body too?"

......

Zhang Hao rolled his eyes speechlessly: No, there is no rust in your body, your brain is funny~~~

After being busy for a long time, Zhang Shengye came in a chic manner, although his face was pale, but he did not hide his demeanor.

When they met, they said directly: "Little mouse, you have such a big face." The prime minister is here, and he has arrived at the guild. I'm waiting for you now. Feng Dongyuan is already waiting for you in the living room. ”

Zhang Hao was suddenly surprised: "The prime minister is here in person......?" Second uncle, isn't it...... Playing big?"

"I see you're quite bold, why are you scared now?"

"I heard that prime ministers are all seven-minded and exquisite, and dealing with these people requires multiple hearts. But I'm just an ordinary person, if I have more eyes in my heart, I'm going to die......"

Zhang Shengye: ......

The credit clause was facilitated by Zhang Hao, and Zhang Hao still had to go.

Feng Dongyuan returned to a cold face again, and when he saw Zhang Hao without saying a word, he pulled it up, and flew away with a hula, no matter what Zhang Hao said along the way, he didn't slow down.

When Zhang Hao came to the gate of the guild, his legs and feet were weak and his face was pale. A smug smile appeared at the corner of Feng Dongyuan's mouth, "Let's go in, the city lord is also here." ”

Liu Jingming, the lord of the city, and Ouyang Si, the prime minister, sat in the north, condescending;

Zhou Bo and the others in the guild sat upright in the south, a little uncomfortable.

Zhang Hao came in and saw this, frowned slightly, and asked, "Which is the prime minister?"

"The old man is!" the prime minister looked like he was middle-aged, but he called himself an old man. However, the life span of a cultivator cannot be seen on the surface, and there is nothing wrong with calling himself an old man.

Zhang Hao looked at the other party, nodded seriously, and said domineeringly: "Hello Prime Minister, you are sitting in the wrong position!"

The atmosphere stiffened in an instant.

Liu Jingming's whole body tensed, and he was really shocked by Zhang Hao's words.

Zhou Bo and the others were also stunned. Zhang Gongzi, you are domineering!

And Prime Minister Ouyang Si narrowed his eyes, and his eyes shot straight into Zhang Hao's heart like a knife. But Zhang Hao held his head high, looked directly at the prime minister, and did not back down.

In the air, there seemed to be an invisible sword and sword shadow.

After a while, the prime minister laughed: "What a young man." So you say, where should the old man sit?"

"Of course it's where the guests should be sitting. After a pause, Zhang Hao continued, "Let's talk again in the afternoon." At noon, let's first pick up the dust for the prime minister, and by the way, introduce the Xuantie Guild. ”
