"That's the case, there are many kinds of orcs, among which werewolf cavalry is equivalent to human light cavalry, minotaur and bear man are equivalent to heavy armor warriors, tiger people, lion people, leopard people, these are equivalent to our knights, in addition to these ordinary orcs, there are orc temple warriors, temple warriors, temple knights, as well as temple knights, sacrifices and other professions, among which the highest status is the orcs in the orcs of the three royal families, the lion, tiger and leopard three clans, and the other is the temple sacrifice and the temple knights, with a strong halo power. Sardin said.

Luo Heng heard so much, what exactly the orcs looked like, Luo Heng was not very clear, Luo Heng continued to ask: "Is it possible for the orcs to detect our artillery?"

When Satin heard this, he suddenly became vigilant and asked, "Cheney, you mean that the orcs will come to find out?"

"Teacher, that's for sure, the wolf cavalry died so many in a short period of time, everyone would doubt it. Luo Heng nodded and said.

"Shall we hide the artillery, if it is discovered by the orcs, there will be no such good thing as today. "Satin knows that the lethality of artillery is very high, that is because those orc werewolf cavalry do not have much protection, if you change to a bear man holding a wooden shield, then you can only use solid bullets, but the speed of the orcs is very fast, and only by increasing the number of artillery can it make up for it.

"Why don't we disguise it?" Luo Heng said.

"Why don't you hide it?" Satin looked at Luo Heng and asked suspiciously.

Luo Heng said in a low voice: "Teacher, you said that if the orcs didn't find something unusual, what would they think, would they still be fooled? Let's let the orcs find something, but we're not afraid, so what will the orcs do?"

When Satin heard Luo Heng say this, he looked at Luo Heng in astonishment, if it weren't for Luo Heng's bones being adults and being a dwarf, Satin would have wondered if Luo Heng was a human being.

"Teacher?" Luo Heng shouted tentatively as his scalp was numb from being stared at by Satin.

"It's okay, it's okay, okay, I'll leave this matter to me, and we'll let the orcs do it again. Satin immediately woke up, and the thought of the orcs who had followed him to give him a human head, Satin couldn't help but be excited.

"Teacher, I still want to know something about minerals. Luo Heng took the opportunity to make a small request of his own.

"Go, come back with me, I'll give you that thing about ore, mining, prospecting, sorting ore. Satin began.

Luo Heng followed Sardin to the forging area where the dwarves were, and the dwarves here had already known about this record, and they all looked at Sardin excitedly.

"You guys do a good job, everyone has the gold coins. "Satin originally wanted to rotate these dwarves, but Luo Heng didn't let him, because it required training to control the artillery, and Satin immediately stopped exchanging when he heard that it might delay the speed of killing orcs.

"Teacher, we also want to kill the orcs with our own hands. Waddin pleaded.

"Go, beat a hundred pounds of fine iron, don't beat it to pass, you are not allowed to eat. Satin shouted as he pointed his turnip-thick fingers at Wodin.

As soon as Waddin heard this, he was stunned and hurried to do it, and the other dwarves saw this scene and dodged away one after another.

"I think it's too much wine, a bunch of cubs. Satin shouted angrily when he saw that the other dwarves had left.

Luo Heng followed Sardin to Satin's house, and Sardin directly took out a huge box that was one meter high, two meters long, and one meter wide.

"There are all kinds of ores, there are more than one hundred and thirty kinds of them, this is iron ore, this is copper ore, this is silver ore, this is gold ore, this is mythril ore, this is Mithril ore associated gemstones, this is ruby, this is emerald, this is ....... "There are five drawer-like compartments in the chest, and there are small squares in the compartments, and there are a lot of ores in the small squares.

The big one is the size of a fist, and the small one is the size of a thumb, Satin said: "See it for yourself, touch it yourself~ touch it, weigh the weight, and then taste it, I tell you, Cheney, the group of cubs outside haven't seen it yet, do you see, this piece of pure gold ore is worth at least more than a thousand gold coins, you get familiar with it first, and I will teach you what to temper these ores in the future, as for the exploration of ore veins, it will take longer." ”

"Thank you, teacher. "Luo Heng saw so many good things, and saw the egg-sized raw ore ruby, this ruby has not yet been polished, you can see that the transparency is very high, the color is also very pure, and the value should be very high.

"You can come to my house in the future, study slowly, and when you return to the Dwarven Kingdom, I recommend you to go to the Engineer Academy, where there are more ores. Satin patted Luo Heng on the shoulder and said.

"Thank you, teacher. "Luo Heng is also very excited, what is needed to make artillery and shells, that is, minerals, all kinds of minerals.

As for how to purify the minerals, hehe, Luo Heng felt that it was more convenient to hand them over to the dwarves.

Luo Heng is responsible for making more artillery, although the artillery is not sold to the northern fortress, but it needs to be used by the dwarves, according to Sardin's requirements, the artillery needs one per dwarf, and there are more sub-cannons, because the sub-cannons need more convenient to cool down.

And *, projectiles, for which the Northern Fortress gave a group of slaves to the dwarves, and these human slaves would later become Sardin's private property.

As soon as Sardin changed hands, he handed it over to Luo Heng, so Luo Heng had nearly fifty slaves in the blink of an eye, these slaves were all tall men, but their bodies were thinner than their families, but the skeleton was still very large.

At the same time, there is also the information of these slaves, Luo Heng took a look, they are all soldiers who were captured in battles between nobles.

As for the various materials, they were sent to the dwarf forging area like flowing water, in order to confuse those people outside, and also to keep it secret.

Sardin deliberately asked for some unwanted materials, and Luo Heng also asked for some fire-based magic crystal powder, because it was said that this fire-type magic crystal could increase the power of combustion.

There are some other magic crystal powders, but one of the magic crystal powders is just given to a cloth bag, and each one is only about two catties at most.

"Cheney, don't touch the iron with this magic crystal powder, the flame or something, it's very familiar with the impact, otherwise the consequences are unpredictable. Sardin also gave Luo Heng a warning.

When the materials were sent and the people were delivered, it was already the middle of the night, and Sardin hurried to the first floor of the fortress to prepare for deceiving the orcs, as for how to deceive, there was no need for Luo Heng to worry about it.

"Throw*!" After transferring more than a dozen humans involved in the production of artillery from the first layer, and five dwarves to assist, Luo Heng began to supervise the production of artillery.

The casting of the cannon was carried out by two dwarves, and the human slaves were more likely to extract sulfur and saltpeter, while charcoal was directly crushed with a sledgehammer.

When configuring, Luo Heng personally configured, and then made this * into a medicine bag, and the medicine bag was packed in a cloth bag with water, and there was no way to do it, only when the medicine was loaded, the cloth bag was taken out.

* The production of projectiles, the production of artillery, among which the most people are polishing artillery, the smoother the artillery, the more powerful it is, mainly because of good sealing performance.

In addition, Luo Heng also asked some carpenters to make wooden stoppers of the same size according to the caliber of the sub-cannon, one to seal it, and the other to be able to easily put it in.

This is what is needed when the solid bullet is fired, * After the medicine is packaged, a wooden plug is used, and then a solid bullet is put in, and the increased range and power are much higher than those without a wooden stopper, because of the relationship between the chamber pressure.
