"They'll believe it. Watt whispered a word of defense, looking very unconfident.

"You don't believe it. Watt, if you still want to continue your quest for mechanical power, then come with us, there is a place where all your dreams can be realized, and the famous alchemist Sera of the continent is also there, you are the one he recommended. ”

"What? Serra, he recommended me? What place are you talking about?"

Watt asked in surprise, he didn't expect Sierra to be there, and he offered to recommend himself.

"Storm Castle! Lord Duke is the most enlightened lord in the world, he can accept all ideological atmospheres, and there are the most advanced alchemy laboratories on the continent, and there are also the top scientists, who are commonly known as alchemists on the mainland,"

Storm Castle Watt fell into doubt, he had heard of Storm Castle, but this place was not very remote and backward, and there was even a risk of being attacked by monsters at any time, how could there be the most advanced alchemy laboratory on the continent?

Just as Hera was talking to Watt, Alice struggled to say, "Hera Witch, you must take him away quickly, my magic power is insufficient." ”

Hallucinating two Teutonic knights is a very difficult thing for Alice, after all, she is still young and has a short time for her magical talent to awaken, so her magic power is limited.

"Watt, we must leave, or we will not be able to leave once the Teutonic knights wake up. ”

Hera said with a serious expression, and at the same time, the magic in her body began to work, if Watt still did not agree to leave, then she had to use the strong one.

"I can leave with you, but you must take my companions with you. ”

"Who is your companion?"

"A red-bearded dwarf imprisoned on the lower floor. ”

Dwarf, Hera had a hint of surprise on her face, but she quickly decided: "Alice, you hold on. Rose, directly use spatial magic, and take me to teleport to the dungeon on the first floor to find the dwarf. ”

"Hmm. Rose nodded heavily, and almost instantly, the space began to distort, and then the figures of Rose and Hera disappeared from sight almost at the same time.

Seeing this magical scene in front of him, Watt's face was full of surprise. At the same time, it can also be detected from the previous title that the women in front of them are all witches. It's just that compared with the ignorant people at the bottom, Watt doesn't have any discrimination against the identity of witches, because he has come to understand that blaming witches for the spread of the plague and disaster is pure nonsense.

However, in the dungeon of the Inquisition, it was still a very shocking thing to see the appearance of a witch. What kind of character is this Storm Lord, and why does a witch work for him?

Before Watt could figure out what was going on, he saw Rose and Hera coming up with a red-bearded dwarf. Compared to Watt's hesitation, the red-bearded dwarf was much more hearty and direct, and he just had to escape from this place quickly, regardless of whether the other party was a witch or not.

Rose's forehead was full of sweat at the moment, teleportation was originally very expensive for magic, and this time it was with two people in an instant, and the magic energy on Rose's body was almost consumed.

Hera naturally sensed that the two little witches, Rose and Alice, were already in a limit state, so she hurriedly said to Watt: "I have already brought you out, hurry up and leave, otherwise you won't be able to leave!"

The red-bearded dwarf also shouted in a rough voice at this time: "Watt, what are you hesitating about, if you don't leave, we will all go to the gallows!"

Facing the urging of the red-bearded dwarf, Watt finally made up his mind at this moment, he nodded and said, "I can go to Storm Castle with you, but whether you stay there or not, I will see if what you said before is true." ”

"Don't worry, you'll be surprised when you arrive at Stormcastle. ”

After Hera replied, the group quickly evacuated to the previous confessional room. Here Watt and the red-bearded dwarf changed into the robes they had prepared to cover their bodies, while behind the Inquisition, a carriage was parked.

Sitting in the carriage and leaving Andorra City with the flow of traffic, several people on the carriage breathed a sigh of relief. Perhaps Andorra has been peaceful for too long, and the vigilance in all aspects has been exhausted after hundreds of years of stable life.

It's not like Stormfort, almost all the people are in a kind of crisis, so Duke's coming to Storm is a disadvantage, but it's also an advantage. They have a long-term sense of crisis, so everyone contains a kind of blood, and suffering makes them not so devout about the so-called religion. Therefore, everything has two sides, and there must be advantages and disadvantages.

It's just that Hera didn't notice it, there was a pair of eyes that had been watching their actions, standing behind them and watching all this coldly.

......

While Hera and the others were back at Stormcastle, Duke was discussing with Serra about the transformation of the metal process and the proportions of the various alloying elements. Fortunately for Duke, the famous Forla Alchemy Laboratory on the mainland is indeed not in vain, and they have recorded all kinds of metal reactions in detail during hundreds of years of alchemy experiments.

And these records will be a great asset to metalworking. As a simple example, the most suitable steel for large-scale equipment for weapons is 65 manganese steel, which is numbered by modern industry. Generally speaking, it is a medium carbon alloy steel with a carbon content of 0.62-0.70%, which is also called spring steel in later generations.

Because the carbon content is a decisive factor in the hardness of the steel, if the content is too low, then the hardness of the steel is not enough, and if the content is too high, the steel is brittle and cannot be used. Therefore, in the entire ancient society, the quality of steel was determined by the metal content and carbon content in it.

And this kind of spring steel has enough hardness and toughness, and it may not be as good as some alloy weapons in terms of ultimate weapon performance. However, it has incomparable advantages over other alloys, that is, the cost is cheap, the process is simple, and it is suitable for mass production.

Just like the Tiger tank built by Germany during World War I, the thick leather cannon has strong performance. But in the face of the Soviet T34 tank sea, the end is the end of being blown up. Because war is never a heads-up, especially in large-scale wars, weapons become consumables, and cost and output are the most important

In the past, the blast furnace steelmaking in Storm Castle was actually refining this kind of medium carbon alloy steel, but there was no accurate understanding and specification of the proportion of carbon content. To put it in layman's terms, the carbon content in steel is casual......

But even if it is so, because the furnace temperature is high enough, and the hydraulic hammer forging can also easily hammer out the impurities in the steel billet, so even if the carbon content is dependent, as long as it is within a general range, it still creates a plate armor that is ahead of the entire continent.

And now that Serra, a professional alchemist, has joined, Duke can let him go through the experiment and determine what proportion of carbon is most appropriate. And not only that, but Duke was able to allow Sierra to test a variety of metal reactions, using a more standardized, industrialized process to create a variety of alloys.

For example, at present, Duke needs the most steel alloys such as manganese steel, titanium steel and so on. Because before the advent of composite carbon fiber materials, the most suitable material for armor was titanium steel. Titanium alloy armor is more than twice as light as steel armor with the same defense, and titanium alloy has more than twice as much defense as titanium alloy with the same weight.

In other words, if the titanium alloy armor is successfully developed, if the weight is not reduced, the defense of the storm armor will be more than doubled. If the defense remains unchanged, the whole body armor of about 70 catties can be reduced to less than 30 catties, and this change in weight can definitely make the hoplites have the flexibility of light infantry, and there is no need to worry about rapid corrosion and rust.

Only with the advent of these alloy steels, then the weapons and armors of Storm Castle will reach a point that this world cannot compare with for the time being, at least a gap that large-scale mass production will never be able to achieve!

This is the qualitative change brought about by the change of technology, and Duke's expectations for steel are not limited to cold weapons, and in the future, hot weapons such as gun barrels and gun barrels will also need high-strength alloy steel, so Duke will attach so much importance to Serra, and even willing to take out the secret of firing porcelain, and leave him in Storm Castle.

War has always been the driving force behind the development of human weapons.
