"Mo Xuan, I've found a way, look. Lu Sien's little short legs pounded quickly, like a gust of wind, and the fiery red beard that had turned into Xiao Zhi also flew with the wind.

"Slow down, don't rush. Mo Xuan stretched out his hand and took the item handed over by Lu Sien: "What is this?" It's not that Mo Xuan is lonely and unheard, but there are too many species that have not been seen in this world.

"Fire sticks to iron. Lu Sien proudly explained to Mo Xuan: "This kind of iron once became the last most popular material in the world, but due to its characteristics, it eventually became a waste product. ”

Lu Sien had an expression on his face that he asked me, and Mo Xuan had no choice but to satisfy him: "That's why." ”

Sure enough, Lu Sien's face showed a satisfied expression: "The characteristics of this iron are very special, first of all, the melting point of this iron is very low, and even this iron can be melted with firewood, and secondly, after this iron is melted for the first time, it is not only very hard, but even some well-known weapons can't compare to it, but it is very difficult to melt again, and some people even used ninth-level magic to make him red." ”

"But that's not enough to make it a waste!" Mo Xuan asked appropriately, and the satisfaction on Lu Sien's face became even stronger: "And isn't this all an advantage? This shows that his resistance to demons is very good." Mo Xuan played with the black mineral in his hand.

"I'm not done yet!" Then Lu Sien cleared his throat: "Then there is another property of this iron, that is, adhesion, put two pieces of this iron together, about ten days! You will find that this iron is very tightly bonded, even like they are meant to be." However, this property only appears after the first melting, and if it is not melted, nothing will happen. If it's just these to nothing, the key is that the last time this characteristic was discovered was very late, and I don't know which country used this iron in large quantities as weapon materials, it was in peacetime, and then one day the war broke out, and when the soldiers went to the arsenal to get weapons, they found that all the weapons were glued together, and the rebels were using inferior weapons because they had no money, and then the country was greatly damaged, and even the imperial capital was captured. ”

After listening to the last story, Mo Xuan was speechless: "And then this kind of iron was abandoned?" Mo Xuan felt incredible, although he couldn't make weapons, it was also very good to make other things, such as the walls of the silver vault or something.

However, Lu Sien was a little daze at Mo Xuan's question: "Of course, you can't even make weapons, what else do you want it to do, armor?" It seems that the dwarf who loves to strike iron has nothing else in his eyes except weapons.

"Then what should we do?" Mo Xuan tossed the mineral in his hand to Lu Sien.

"Here's our plan. Lu Sien unfolded a schematic diagram of the volcano's interior: "We plan to dig out a circle around here, about twenty meters from the lava, and this circle is about ・・・・・・ high. ”

"In other words, we just need to add a plug to the volcano, and this plug is made of this fire sticky iron, right?And then the bottom of this plug becomes a sealed space, and not even a trace of lava can be revealed, right?" Mo Xuan's hands gestured in the air in a circle.

"That's right, like a kettle lid. Lu Sien smiled happily, a very vivid analogy, which showed that Mo Xuan still understood their plan very well.

"Wait, I've got something to think about. Mo Xuan held his forehead and thought carefully: "Lu Sien will repeat what you just said." ”

"That's right, what's wrong. Lu Sien was very depressed, what happened to Mo Xuan?

"No, the next sentence is the next sentence. Mo Xuan's expression was very impatient, as if the climax was coming but suddenly receded, and he couldn't hold it, which was quite uncomfortable.

"Like the lid of a kettle?" Lu Sien said with confusion.

"Yes, kettle lid, kettle lid. Mo Xuan's expression of joy became hideous: "Damn, how can I forget, although these are two worlds, there are still some similarities." How can I let these habitual thoughts freeze my imagination. ”

Mo Xuan's hideous expression began to slow down, calming his mood, but his excited expression never lowered: "Lu Sien, please bring your clan and all the magicians." ”

Although he didn't understand what Mo Xuan was going to do, Lu Sien still obediently went to find someone.

Then Mo Xuan stretched out his hand to spread out a huge leather scroll, and then began to write and draw on it, and in less than a while, a complex three-dimensional view was displayed in front of Mo Xuan.

"Mo Xuan, what are you looking for us?" Jim's face was dripping with sweat, followed by mages and dwarves who were also dripping with sweat.

Jim and his men are not idle these days, and they use all kinds of magic to help the workers. From their hearts, they are reluctant to do this kind of degrading behavior, but if Mo Xuan secretly tells them to consume a lot of magic power and then recover, then they can quickly improve their spiritual power and magic power, so that after a few days, whether the spiritual power of these magicians has improved or not, they have not felt it, but their proficiency in various magic spells has been greatly improved, so that the magicians who see the benefits, including apprentices, will also work obediently without Mo Xuan's persecution, so that they have won some praise.

"That's right, aren't we discussing how to stop the volcano?" Mo Xuan had a smug smile on his face, but in Jim's opinion, Mo Xuan's behavior today was very strange.

Lu Sien next to him nodded and said, "That's the case." ”

"I had an idea that I was going to put this volcano to good use, why would we have such a huge treasure in it. The smug smile on Mo Xuan's face was even worse.

"Wait, Mo Xuan, I don't understand where the treasure you are talking about?" Lu Sien was confused by Mo Xuan's goods again.

"You'll find out here. Mo Xuan unfolded the drawings he had drawn: "We know that when the water is steamed, the lid of the kettle will be opened, and this force is very huge and ・・・・・・. ”

That's right, Mo Xuan made them see that it was a steam engine, and it was a steam generator, using the entire volcano as a boiler and adding some equipment, such a huge generator would be successful, and because there was no need to think about the fuel, there was no need to worry about the environmental protection of this generator.

"That's ・・・・・・. Mo Xuan explained the role of each part on the drawing: "What's the problem?"

"Well, Mo Xuan, your idea is quite good, but this is just an idea, we can't just go there... Lu Sien's hands kept gesturing, but he didn't know how to say the next sentence.

It was Mo Xuan who understood his thoughts: "Experiment, yes?"

"That's what it meant to me. Lu Sien nodded happily, just understand.

"I know everyone's worries, and you haven't touched this thing, but this steam engine is not completely without provenance, it seems that goblins make this kind of thing, and as for power generation, you don't have to worry about it, I can assure you. Mo Xuan explained seriously, and even the hearsay goblin steam engine was added.

"Well, you convinced us. Lu Sien nodded helplessly, it seemed that Mo Xuan's stubbornness was no worse than that of a dwarf.

Then Mo Xuan's words annoyed the dwarf: "The big question now is whether you can build the various parts of this machine. ”

"Are you despising the dwarves' iron-striking skills? Lu Sien grabbed the blueprints and walked away with a group of disgruntled dwarves.
