"The flame in Lu Yang's hand is the true fire of the Yuan Infant Stage, but Lu Yang practices a peculiar technique of absorbing purple qi every morning to nourish the fire, so his flame is much stronger than the ordinary Yuan Infant True Fire, and the appearance is different.

The flame in Zhang Xinhan's hand is a unique kind of fire in the Jiuyang Sect, called 'Red Lotus Earth Fire', which can fully bring out the characteristics of spiritual materials. ”

Zhang Hao silently wrote it down. The world of practice is more complex than the world it used to be, and there is so much to learn.

"Gilding" is a delicate job. Lu Yang finished at noon, while Zhang Xinhan didn't finish until the evening.

Everyone gathered together, but everyone's eyes looked at Zhang Hao. Although Zhang Hao's cultivation is the lowest, no one can ignore Zhang Hao. These "steels" were provided by the Zhang family, and only Zhang Hao was the most qualified to speak.

The development to the west was proposed by the Zhang family;

The strategy of boiling the sea was also proposed by the Zhang family;

high-purity dark iron, which is also provided by the Zhang family;

And the current person in charge of the Zhang family is Zhang Hao!

The most important thing is that Zhang Hao's identity as an 'inner disciple of the Xuanzhen Sect' also makes Zhang Hao even more different. I have to admit that it is good to have a good backer.

Without Zhou Jue, Lu Yang, and Zhang Xinhan, Zhang Hao can ask the Xuanzhen Sect for help, and he can find someone else. But without the Zhang family, everyone is afraid that they will not be able to find a second family for the time being.

Especially Feng Zhiling, who was hanging next to him, reminded everyone from time to time: Zhang Hao, you can't move!

Zhang Hao's gaze slowly swept over everyone, very satisfied with everyone's gaze. In everyone's expectation, Zhang Hao smiled: "The formation seal is carved, activate it and see the effect." Even though it's only one pillar, you can see some of the effects. ”

The two pillars were quickly activated, and a layer of red flames appeared on the surface of the pillars.

Zhang Hao was surprised to see that this flame was not in direct contact with the pillar, but suspended on the surface of the pillar, about ten centimeters away from the pillar. In this way, the pillars will not be burned by the flames. Even the flames formed a protective layer.

Zhang Hao's eyes wandered between the two pillars, and gradually found the difference.

The flame of the pillar carved by Lu Yang has chaotic ups and downs, while the pillar carved by Zhang Xinhan has an orderly undulation of the flame evenly and like a wave, and there is a faint sense of surging.

As time passed, the true elements injected into the pillars gradually ran out, and the flames gradually extinguished, Lu Yang's pillars were the first to be extinguished, and Zhang Xinhan's pillars were extinguished only after tea.

It is clear which is better and which is inferior.

The pride on Lu Yang's face turned into embarrassment. And most importantly, scrapped a pillar, which ...... O sin!

A pillar is 100,000 catties and is made of 96% pure black iron. Although the Zhang family did not give this kind of steel an offer, it is obviously not cheap. With the quality of this kind of steel, it is not a problem at all to increase the price by three or five times.

Even if it is calculated according to 96% of the dark iron, 100,000 catties are worth 70,000 high-grade spirit stones! And now, it's just wasted! Oh, there is still pure gold not calculated.

Zhang Xinhan still has a peaceful smile on his face, but this smile contains a faint sense of pride, which is not impetuous pride, but a kind of self-confidence! A kind of pride in defeating the opponent!

This time, he was the victor of the Seal Carving, and next, he would be in charge of refining an unprecedented, super-powered, Heavenly Fire Array.

Zhang Hao slowly glanced around and said loudly: "Now I announce that I will invite Zhang Xinhan to be the person in charge of this Dutian Fire Array. ”

"Thank you. Zhang Xinhan generously thanked him.

"Thank you also for the support of my seniors. Now, let's discuss together, the refining of the Dutian Fire Array. Here's how I envisioned it:

Using the Dutian Fire Array, we will heat up a part of the sea area, and in a relatively mild way, carve out a sea area that belongs to us from the sea. For the sea monsters, we drive them away, not kill them.

We will try to minimize direct conflict with sea monsters, or even no conflict.

This time, the purpose of our exploitation of the sea is not for the monsters and resources in the ocean, but only to 'borrow the road'! We want to open up the passage of the sea.

Once we have a piece of sea, we will start building a port and building a ...... Big steel ship!

Yes, it's the steel that builds the ships out of steel, the same material as these steel pillars, to build the impregnable steel fortresses of the sea!

These fortresses will be hundreds of meters long and have a displacement of thousands or even tens of thousands of tons. Even if the turbid waves are monstrous, they can't shake the slightest!"

The crowd was shocked, and some people were already imagining: a castle made of steel, into the sea...... Boom, sink!

Some people are also thinking that the ship made of steel was besieged by countless sea monsters, but it did not move at all, cutting the wind and waves. But...... How can this heavy steel ship be driven? Tens of thousands of tons, not tens of thousands of catties, and the infant period will be jaw-dropping.

Zhou Jue was the first to speak: "Brother Shi, I have a few questions, this is built with steel, even if it can float, but if you want to drive such a huge ship, you also need a large number of spirit stones.

In this way, even if we can open up the ocean pathway, the cost alone will be enough to bring us down.

According to some of the technical indicators we have recently compiled, we have calculated that if we want to drive a ten-ton weight of the lowest-level war weapon, we will also consume about a thousand lower-level spirit stones per hour.

If you want to drive a ship of 10,000 tons, this will consume at least 100 high-grade spirit stones per hour, and the cost of a round-trip spirit stone will be as high as 72,000 high-grade spirit stones for a month. If you calculate the cost of manpower, defense, etc., it can easily exceed 100,000 high-grade spirit stones.

Also, until now, we didn't know what the price of steel was. ”

"The price of steel...... It's three times the size of the same level of Dark Iron!"

Hiss...... There was a sudden sound of cold air all around. Although there is speculation, the research is shocking to hear this answer.

Zhang Hao looked around in his eyes.

The market price of 96% pure Xuantie is 70 medium-grade spirit stones per catty, and the contract is 14,000 lower-grade spirit stones per kilogram.

The price is three times, which is 42,000 lower grade spirit stones per kilogram. If this is to build a 10,000-ton ship, then ...... The numbers are exaggerated!

Apparently everyone thought of this as well.

But in Zhang Hao's heart, he was calculating another account:

Because of the progress of technology, the Zhang family produces a ton of dark iron with a purity of less than 96%, and the cost price is less than 10,000 spirit stones, of which half of the spirit stones are ground to make additives for the smelting of dark iron, one percent is given to workers, three percent is given to machinery and equipment and related technical personnel, and the rest is the cost of materials.

And now Huang Mingshan and others are studying the use of oil to replace the spirit stone, and there is hope that the cost price will be further reduced.

In steelmaking, because of the large use of oil, not counting the oil itself, the cost price of steelmaking is only about 10,000 spirit stones - mainly to arrange the array and promote the consumption of flames.

In other words, the Zhang family produces one ton of 96% purity steel, and the cost price does not exceed 30,000 lower grade spirit stones.

But technology is worth it!

However, Zhang Hao also knew that if he wanted to cooperate, the Zhang family obviously could not go according to the market price, but how to reduce the price was also a very serious issue.

In the past thousands of years, the price system between Xuantie and Lingshi has been relatively stable, and if there is any fluctuation, it is nothing. But if the Zhang family suddenly launched the price of cabbage, Zhang Hao did not dare to guarantee what would happen to the market.

But the biggest possibility is a tsunami, with countless people blocking the gates of Zhang's house and demanding that the technology be made public. Someone will even directly destroy the Zhang family!

Therefore, how to quote, Zhang Hao is also thinking about it. If one is not good, the Zhang family will fall into the abyss.

The surrounding cultivators were still shocked.

The previous few who participated in the seal carving formation, they looked at the carving knife in their hands, silently felt the elite of the carving knife, they ...... Approved the price!However, I always felt that something was wrong.

Zhou Jue was the first to ask: "Brother Shi, this price ...... It seems reasonable. But there's one thing I don't understand. ”

"Brother, please speak. "Zhang Hao doesn't say 'Brother Zhou' anymore.

"According to the price of Xuantie, the Zhang family is only afraid that they don't have the ability to produce so much Xuantie, right? I wonder how much the Zhang family's Xuantie cost?"

As soon as Zhou Jue's words came out, everyone's eyes swept towards Zhang Hao.

Everyone is not stupid, although they were shocked by the series of miracles of the Zhang family. But when Zhou Jue pointed out this problem, everyone reacted:

Even if the cost price of Xuantie is half or even a quarter of the market price, your Zhang family does not have the ability to produce so much Xuaniron.

Don't say anything else, just say that the fourteen steel pillars at the moment are 1.4 million catties, and according to the market price, the entire country of Qixia will be sold, and I can't afford it!

Zhang Hao coughed twice: "This ...... Brother Shi, the agreed price on the market, 96% of the dark iron is a pound of 70 medium-grade spirit stones, right?"

"That's right!" Zhou Jue nodded.

"Then I'll calculate it according to this price, no problem! I admit it, the Zhang family's technology has improved. But the progress of technology is the result of our efforts, not everyone!" Zhang Hao's words are quite reasonable.

Everyone was stunned. Yes, that's right.

Zhou Jue covered his head in pain: "Brother Shi, what I mean, is that if the Zhang family continues to calculate at this price, it will be difficult for us to continue to cooperate in the future." ”

"Oh...... How so?"
