After more than ten days of construction, the iron-making blast furnace on the banks of the Seine was finally completed, and the magic array laid by Gandalf was also completed at the same time.

And the hydraulic blower, hydraulic hammer forging machine and other supporting facilities next to it were also completed at about the same time, and the gear set and crank shaft were finally completed in this world with the joint efforts of Galileo and Bruno.

Duke stood in front of these buildings that still seem to be simple, his body even trembled slightly because of excitement, because no one in this world knows the meaning of these hydraulic machinery, which represents a breakthrough in the use of natural power by human beings, and represents the application of human beings in the initial stage of industrialization!

Gandalf and Hera and their group of magicians also arrived, as Duke had promised them that would give them a glimpse of the true power of science. This is not the little trick of the previous lever principle, when the steel machine is revealed, it is full of an indescribable mechanical aesthetic!

Duke came up to the hammer machine, which was fully tuned, and waited for Duke to open the gates, and then with a force of more than three hundred kilograms, it was running at a speed of more than a hundred beats per minute. And that's just the beginning of commissioning, which, if fully loaded, can reach the late Middle Ages with a force of more than 500 kilograms and a speed of 200 beats per minute.

"Gandalf, I promised you a glimpse of the power of science. Today's time has finally come, and you will see superpowers far beyond human power!"

Duke was excited, but Gandalf's face was full of doubt, not just them, but everyone except a few of the main design-builders didn't understand what Duke was trying to show.

Gandalf is no stranger to this hydraulic machine, and it can be said that this hydraulic hammer forging machine was rebuilt on the basis of the previous hydraulic mill. They didn't think there was anything strange about it, except for the addition of a sledgehammer and some strange things, they didn't feel any essential difference, so they didn't really believe Duke's words.

Seeing the suspicion on the faces of these people, Duke didn't explain too much, he just smiled and came to the side of the hammer forging machine, and then pulled down the sluice. With the impact of the drop caused by the introduced Seine water, it rushes into the rollers below, driving the entire gear set and crank shaft to operate!

The sound of "Knock~~Knock~~Knock" began to sound, and then I saw the hammer collide with the iron cutting board below at a crazy speed, and the force was so great that I could see sparks sputter out.

Gandalf was completely stunned by the sight in front of him, he had never imagined that the slow-moving hydraulic mill of the past could become so powerful as it was. And with Gandalf's knowledge, coupled with the iron-making blast furnace built next to him, he instantly understood what the appearance of this hydraulic hammer forging machine represented, which would represent a qualitative improvement in Storm Castle's military equipment!

"This ...... It's amazing, I can't believe my eyes!"

Gandalf was really shocked this time, and it is not too much to say that this efficiency is dozens of times higher than that of the Iron Master. What's more, as long as the Seine continues to flow, this machine will always run tirelessly, and what kind of manpower can reach this level of madness?

"If you don't see Gandalf, this is the power of science, and if you think it's just a hydraulic machine, if it's ten, hundred! Or more efficient industrial machines are developed, what kind of scene will it be, how small do you think manpower is in front of this mechanical force!"

When Duke himself said this paragraph, there was a kind of yearning and fascination on his face, not that he was performing, but in the hearts of many men, there is a heavy industrial plot, and the shock brought by the beauty of machinery is also fascinating.

Gandalf was no exception, he felt the power of the Hydraulic Hammer Smith, a power that was completely different from magic. He slowly walked to the hammer forging machine, feeling the sound of the knock, and even the sparks that were smashed splashed on his clothes, he didn't move away in the slightest.

"Shocking, really shocking, Duke, you showed me the origin of another superpower, maybe that's what you call science!"

Gandalf spoke to everyone present, this is indeed another superpower, if what Duke said comes true, then the production efficiency of Storm Castle will far exceed that of the entire continent, and the poverty and weakness of the past will be gone forever!

Hera also stared at the machine in front of her, but after all, as a woman, he was not as obsessed as a man, and soon she set her eyes on Duke, her eyes full of wonder and appreciation.

To be honest, Hera had always been skeptical of Gandalf's portrayal before coming to Stormcastle, because she knew the Otto family very well, what kind of virtue Duke was, and he was famous in the imperial capital, just a gentleman who only knew how to eat, drink and be merry.

But from the first time she saw Duke's performance, she had already noticed that Duke's performance was not simple, because his reactions and actions were not something that a gentleman could do. It's just that she should have doubts about Duke's deeds in Stormcastle, how could it be that a gentleman came to Stormcastle and changed so much in just two months.

Even Hera once suspected that Duke was controlled by a soul mage, but Hera did not notice any magic fluctuations on Duke's body after contact. And as a great witch-level self, and the existence of the Grand Magister Gandalf, Hera is very confident that there is no magic in this world that can hide it.

But now everything in front of him has confirmed that Duke is indeed no longer the gentleman in the imperial capital, and he is even better than he imagined. If Stormcastle continues as he describes, it is foreseeable that it will soon become a major city in the Francoian Empire.

At the same time, it also strengthened Hera's determination to let Duke inherit the throne of the duke, because the Dark Witch Society was on the verge of collapse under the suppression of the imperial military god Duke Otto. However, Duke does not have the slightest discrimination and prejudice against the Dark Witch Society and witches, if Duke can be made a duke, then the Dark Witch Society will be given a respite, or even a rebirth.

For the sake of the Dark Witch Society, for the sake of the persecuted witches on Europa, Hera must accomplish this, and only Duke becomes a powerful duke can save it all!
