"I've experimented with a lot of materials, and I've found a perfect replacement so far, and I'm ...... tomorrow No, you'll see the finished product soon. Master Thomas changed his words temporarily.

The word tomorrow is not to be misused.

Bai Xuan nodded approvingly.

If there is nitroglycerin, then it is enough to make nitrocellulose directly from cotton, but the method of making gunpowder in this world is very different, so Master Thomas can only try it himself.

However, this technical problem should actually not be difficult to solve, and it is a matter of time sooner or later.

When the three of them reached the back of the blacksmith's shop, they found that Fili was installing the magic machine, the parts had been made, and the installation was nearing completion.

The shape of the magic energy machine is very strange, it is not the kind of appearance that Bai Xuan imagined, there is no mechanical beauty, only some strange parts and tubes, and there is a square heavy iron box linked below, which is densely filled with magic crystals.

Magic crystals are high-quality ores that are crudely processed into roughly uniform shapes and sizes, and then set in grooves arranged in separate rows.

This is a basic type of magic machine, which can achieve different effects by replacing different parts and components, and achieve functions similar to machine tools - drilling, milling, grinding, cutting, planing, etc.

"Your Highness, why are you here? Filip cried out in surprise, brushing away the hair that hung down in front of her eyes with her oily hand, and rubbing a black stain on her face.

"How's Fili?"

"Most of the problems can be solved, but for the barrel, it's a bit troublesome. ”

"What is a barrel?" asked Master Thomas.

"It's the same thing I told you last time, a solid steel rod with a hole drilled in the center. Fili said.

"You can do it with magic machines, you can drill as much as you want. Master Thomas blew his beard and glared.

"None of this is a problem, the difficulty now is that the drill bit is not hard enough. Filip spread his hands.

In fact, the main problem is that the current carbon steel, the hardness at room temperature should be about the same, Filet believes that this is not a problem, but when drilling, high temperatures will occur, and the hardness of carbon steel will be sharply reduced at high temperatures, and finally lead to drilling failure.

Bai Xuan knows some knowledge about this, the drill bit is generally made of high-speed steel, which has very good heat resistance and extremely high hardness, but it is a steel with complex composition, and he is not sure if he can make it.

"So, you want to drill holes in solid steel rods?" After a long day of discussion, Master Harlem finally understood what this was about.

"Is there anything the master can do?" asked Fili, looking the new magician up and down curiously.

"Why don't you use the casting method?" Master Haring also knows a little bit, "just make abrasives, pour the melted molten iron into it and wait for it to cool." ”

"This method is okay for general steel pipes, but what I need is this, it is used to ......" Bai Xuan paused, "to make a high-demand thing, so the casting method is not good, and it cannot meet the requirements." ”

Drilling is probably the easiest and most compliant method to achieve.

"Then we have to find a way to increase the hardness of the drill bit. Master Harlem said, "Consider enchantments, such as earth-based magic that purely increases hardness, or to think differently, use frost-based magic that lowers the temperature." ”

"That's great news. Filip exclaimed excitedly, "Master, do you know all this?"

"Yes, you can try. Master Harlem said modestly.

"Come on, come on, try now, try now. Master Thomas clapped his hands, more excited than Fili.

Leaving the three of them discussing in full swing, Bai Xuan walked back slowly with his hands behind his back and square steps.

It is not an exaggeration to describe the scene inside and outside the castle as a day, Dong Lei said that the craftsmen and servants currently used have exceeded three hundred, and this number should only be more, in short, Bai Xuan saw at a glance that there were busy people everywhere and various materials piled up, which also meant that spending money was like flowing water, and if the income could not keep up, it would not be long before he would go bankrupt.

Fortunately, there are funds from the royal capital, although the amount is limited, but it can also solve the urgent need, and then it will be self-sufficient, the harvest of this hunt should be able to exchange for a lot of gold coins, and the future reform and taxation can also bring benefits, but at present, it is a bit far from quenching the thirst.

You still have to find some ways to get rich, such as ores and other resources, and I'm afraid you have to go to the Black Curse Forest to find the answer.

For example, Crystal Ore and Alien Beasts.

From a distance, Bai Xuan saw a few people gathered in the corner of the arena, as if they were talking loudly.

"Injecting Dou Qi into weapons can increase attack power, make the destructive power of weapons stronger, and it is very easy to cut off the opponent's weapons, but how can you get Dou Qi out of the weapon?"

"Isn't that a fighting spirit condensed and separated from the body, how can we do it, this is a skill that only a Sacred Domain warrior can master. ”

"And how did Lord Moonbreeze do it?"

"Lord Moon Wind is not cultivating a fighting spirit. ”

......

When he got closer, Bai Xuan realized that these warriors were discussing the so-called sword qi.

Yuefeng stood helplessly between them, and when she saw Bai Xuan coming over, she bowed slightly.

The samurai also hurriedly saluted.

"Your Highness. ”

"Your Highness. ”

"Okay, no need to be polite. "Bai Xuan has never had any aristocratic shelf, everyone knows this.

"What are you discussing?"

"Sword Qi, Your Highness. The samurai replied.

"I heard some of them just now, what do you think of Moonwind?" Bai Xuan asked Moonwind, he also wanted to know how the orc's secret technique was used.

"Your Highness, orcs cultivate the power of nature, I don't know how to explain it, this is innate, and the size of this ability is related to talent and the degree of acquired cultivation. "Moon Wind Dao," this power can also be condensed to the blade, and some skills can release sword slashes. ”

"Sword Slash?"

"It's probably the sword qi you said, a similar performance. Moon Wind said, "Sword Master, the extent I can do it so far can only be released when I use the blade to fluctuate. ”

"What about Blade Storm?"

"The Blade Storm mainly relies on the extreme movement and rotation speed brought by the Wind Walk to form the storm, and the power is attached to the blade and does not spread outward. ”

This is a human meat grinder.

What about the sword technique to ward off evil spirits? Bai Xuan suddenly thought that this sword-breaking technique evolved from the Sunflower Treasure Book, and it should be possible to release sword qi, otherwise it could be so powerful?

However, this kind of sword skill all requires internal force, and it is a completely different system.

Bai Xuan believes that the so-called fighting spirit, internal force, and natural power, including the elves' ability secret arts, are all a kind of use of their own power, and from a broad point of view, they should be the same way, but the details of cultivation are very different, and they probably can't be fused together.

So what do you have? Nothing, except magic.

An idea popped into his head.

Magic can replace everything.

He held out his hand.

"Moonwind, borrow your sword. ”
