Lonely Mountain is a huge mountain that towers over the Great Plains, surrounded by cliffs on all sides, there is almost no place to climb, the post roads carved out around the mountain are very narrow, the only thing that can smoothly enter and exit this mountain country is a huge stone gate called Stein's Gate, the huge stone gate is the only entrance outside the huge mountain, and the core part of the mountain is the famous molten furnace of the dwarves.

"Brother, Lao Tzu's wine, I will invite you to drink it when you win this battle."

The dwarven king looked at the things displayed on the sand table quite helplessly, three catapults that were even bigger than before, were slowly moving forward in the distance, the mechanical sand table had been replaced by the holographic map of the narrator, and the dwarves who had been exploring the mechanical process quickly accepted it after a short period of surprise, and the dwarf kingdom had been peaceful for hundreds of years.

The powerful alliance with the Human Empire allowed the dwarves to devote their best attention to what they loved, and their armies had been reduced to the point of mere policing, and the huge army at the foot of the mountain had made the unprepared dwarves suffer a great loss, and the villages and cities built around the lonely mountain were completely destroyed by the cave people almost overnight.

Few villagers survived the periphery, but the sparse crowd of refugees still gave the dwarves time to completely close the gates that hadn't been closed for hundreds of years.

"I can use my swordfish to destroy these three towers, but you must understand that the only ammunition left for me is all my belongings, and although it is a bit too much to tell you at this time, I need to pay the price."

What the narrator said is the truth, this swordfish is almost completely printed out of the body, in order to maintain the integrity and strength of the body, Dana made the recovery of the resources of an entire cabin, only to barely complete the printing, from a floating wreckage in the universe to recover, sort, and then according to different metal characteristics, polished into metal powder, and finally use ionized advanced printers The energy and waste of raw materials are unimaginable for this dwarven king.

Every bullet on the swordfish is a high-tech product that cannot be mass-produced now, and the world can provide too few things, or just raw materials, which are intended to be obtained through trade or mining, but now Dana's most urgent need is not these raw materials, but the crew who drives the battleship.

Whether it is an agricultural area, an industrial area, or even the boiler room of a warship, it needs considerable technical personnel to operate, and the world is almost in a medieval state, and the prevalence of psionic energy has made the technological development of this world deformed. Only the two races of dwarves and Evelyn can see a trace of technology.

If you don't save the dwarves at any cost, Narrator can say that she only needs Dana's small mass tungsten rod bullet to blow up all the underground cave people on the plain, but Narrator wants to exchange the least price for the maximum reward, and now this swordfish is a very suitable carrier.

"Human, any conditions, Lao Tzu thinks it should be discussed afterwards. The premise of any price is that we are alive. ”

The dwarven king is really a little pessimistic, but it's no wonder that all this is no wonder, looking at the gradually setting sun, at night, the entire battlefield is the world of this group of underground people, with the endless attacks of the undead, basically the fall of the lonely mountain is only a matter of time.

Narrator didn't want to persecute this group of poor people too much, so he nodded:

"I advise you, don't defend like this, although this terrain is very suitable for defense, but tonight I can destroy these three giant catapults, the resources are still in their hands, and there will be more such catapults in two days."

"Our ancestors have repelled countless foreign enemies with such defenses!"

A dwarf who seemed to be a general next to him slammed the table hard, and with great force it bounced the oak cup full of beer on the table with the thump, and the wine in the cup spilled on the table. As soon as the narrator was about to say something, a female dwarf next to him, who seemed to be the owner of the hotel, slapped the dwarf general in the face and slapped him heavily.

"Do you dare to spill the old lady's wine? Lick me clean! If you don't lick it quickly, you won't be allowed to enter the old lady's tavern in the future! ”

The whole meeting suddenly fell into embarrassment, and the deleted general was also stunned, covering his reddened face with one hand, and took out a rough square towel from his pocket and honestly wiped the table.

"Ahem! Cough! Back to the point,"

The king touched his beard in embarrassment, and the dwarven ministers around him were also embarrassed and didn't know where to look, scratching their heads. This female dwarf is the best at brewing wine in the entire Lonely Mountain Castle, she brews beer bubbles without astringency, and she also has an ice cellar blessed by a human archmage.

Every time I take out the wine, I drink it and my stomach is extremely refreshing. Therefore, even the king did not dare to make trouble in her shop casually, after all, scarce things are expensive. Narrator-Jun took a sip of the beer in the cup, recalled in his mind the taste of the Green Island brand beer specially provided by the Imperial Army, and was surprised to find that the beer brewed by the dwarves of this primitive planet actually had a unique flavor.

Putting down the wine glass, the narrator pulled the hologram apart and pointed to the door of the dwarven fortress, although there was no precision in the huge stone block, there were always one or two stones that hit the huge stone gate, and each hit always brought a large piece of broken stone to fall.

"The purpose of the other side is nothing more than to occupy the Lonely Mountain Fort, they are surrounded by the Lonely Mountain Fort outside, and they can attack from a range of almost 180 degrees, so the city gate is under tremendous pressure."

The narrator's then uses his free right hand to list a statistic:

"But if we abandon the gates and leave them open only about twenty meters away, I believe that a large army will be sent from the opposite side to storm the castle directly. Then people on the outside can't see what's going on inside. All we have to do is place our heavy troops on the top, rear, and flanks of the giant gate,"

On the hologram, the narrator drew four green areas, and the green areas immediately refreshed the character of a simulated dwarf, holding a bow and arrow, and a stone block, and attacking a breakthrough of just twenty meters.

"In fact, it is the other way around, and the purpose of war is nothing more than to destroy the living forces of the other side and force the other side to surrender or negotiate."

"Those gray-skinned pointed heads are not all fools, once the casualties reach a certain level, they will definitely change their plans."

Another general hit the nail on the head with the shortcomings of this plan. He touched his beard, which had been tied into a twisted whip, and then pointed to the delicate dwarf demonic nature and said:

"And we don't have ranged weapons in our eyes, and as you can see, we dwarves aren't very good at using ranged weapons. Production is our forte, not war. Moreover, we are naturally very resistant to demons, resulting in a very small number of mages that our race can produce. Most of them are drunkards and half-assers."

"How strong are your manufacturing capabilities? Can something like this be made? ”

After listening to their words, the narrator took out an MG42 general-purpose machine gun from his compressed pocket and placed it in front of a group of dwarves. Not all dwarves are skilled craftsmen, just like humans. Dwarves also have different professions.

"Hey! Hurry up and ask the blacksmith to roll over to Lao Tzu! ”

"Yes! King! ”

The soldier who was named ran away in a puff of smoke. After a short while, a blackened blacksmith came running over, saluted the ministers and the king, and immediately ran to check the black iron bar, and with the help of the narrator, the blacksmith took out a multifunctional measuring ruler made of brass, and after some careful disassembly, a complete MG42 was disassembled into parts.

When the dwarven king's patience was running out, the blacksmith finally took off his glasses and said to the king:

"Your Royal Highness, this Lao Tzu's factory can be manufactured, but it's just ......."

"But what? Say it! ”

"This piece of iron is formed at one time using stamping technology, and we can make it in terms of process, and some small parts can also be polished by hand in the forging factory, which is not very time-consuming."

The blacksmith walked up to one of the guards, then picked up the guard's short sword and slashed at the MG42's heat dissipation sleeve, only to see that after the fire flashed, only slight scratches were left on the jet-black sleeve, and the guard's short sword jumped out of a huge gap.

"As you can see, we don't have such good materials to make it. And I don't know what this thing was made for, so I really don't dare to agree, so please forgive me. ”

The king turned his head to look at the narrator, who had not spoken, and after the blacksmith had finished speaking, the narrator took out a bullet from his pocket and handed it to the honest dwarf:

"Can you make this thing, then?"

After careful study, the head of the forging said firmly:

"It's a work of art, but I don't understand why it's inlaid with phosphorite at the bottom, and we can mix this kind of stuff inside, but not as fine as you. This is black powder that can be rekindled in a furnace that can be extinguished. ”

"Then the matter is very simple, the formula of metal and the recipe of gunpowder can be given to you, so how many such weapons can you produce in a day?"

"Lao Tzu thought that if he went all out, this kind of small brass object could produce more than 100,000 pieces a day, but it would require a new furnace and forging factory, and the process of this black iron rod was a bit complicated, and Lao Tzu felt that there would be a maximum of 10 pieces a day."

The narrator nodded, then smiled at the king:

"Your Royal Highness, your country has been saved, but the price may be very high, you dwarves take out the strongest shield that can be made now, I will show you the power."

The guard next to him quickly handed over the wooden shield with iron in his hand, but the narrator shook his head.

"This thing, it really can't show the power of this gun, is there anything harder."

"How's the pig iron pillar?"

Without thinking, the blacksmith said the hardest thing in his image, pig iron, which was very hard though it was easy to break. Everyone walked out of the hotel in a hurry and rushed to the blacksmith's warehouse, and after a short time, eight soldiers moved out of the warehouse a thick iron pillar with a diameter of two meters and half a meter, which were directly refined from the iron ore and stored here as supplies.

The soldiers quickly inserted the bullets into the canvas cartridge under the order of the narrator, and when a whole cartridge belt was filled with bullets, the narrator inlaid the first bullet of this cartridge belt into the bullet bayonet of the machine gun and closed the top cover.

A group of dwarves were still surprised that the iron rod was not used to knock people, but they were startled by the loud sound that burst in, and after a test shot, the narrator motioned for the dwarves to block their ears, and then pulled the trigger, and finished the bullets on the bullet bag in less than 3 seconds. Before the group of dwarves could react, Narrator had already patted his pants and stood up.

"That's it?"

"Hmmm! It's over."

"Listen?"

"Uh...... Instead of discussing it here, let's take a closer look. ”

The narrator shook his head awkwardly, and when the group came to the rock wall a hundred meters away, they were stunned by the scene in front of them, the entire cast iron pillar was broken into two parts, and the mountain wall was densely covered with bullet holes.

"Stein's beard! What kind of magic is this! ”

"It's not magic, it's technology."

The king, after promising that the narrator would be paid enough, led the group back to the tavern, which was used as a temporary command post, and the group was silent at this point, except for the general.

Although this weapon is powerful, if the opposite side is just bombarding with siege weapons and does not enter the firing range, how can we do it, this attack is obviously very premeditated, and their command and dispatch system is very good, how should we deal with it.

"Capture the thief and capture the king first...... I'll fix this matter. What you have to think about now is to train the personnel to use the weapon as soon as possible, and I recommend using it in groups of 3-6 people. ”

The narrator-kun returned to the swordfish, and in the afterglow of the setting sun, activated the swordfish, and the elf also jumped up with an assault rifle, and the black maid's skirt was blown under the air generated by the rotors. In order to open the city gates, the command system of the underground cave people has obviously become more and more intimate due to the arrival of the night, and the giant catapults no longer send boulders to bombard the city gates.

Instead, they kept smashing skeletons and rotting corpses from thousands of kilometers away to the lonely mountain, most of the undead failed to hit the target, and a few of the undead were quickly slaughtered by the guards who arrived after hitting the target, but this proves that the cave people are not stupid, they learn in the war, and keep improving their tactics, including this flight.

The underground cave people who have seen the swordfish have created a weapon specifically to deal with this aircraft, a huge slingshot, which fires a bone net composed of several skeletons, after launching, several skeletons will consciously form a chapter of white bone net, which greatly increases the chance of hitting, once hit, although it will not cause any damage to the swordfish, but the extra weight hanging on the fuselage, the skeleton soldiers who can be freely combined, will invade the cabin as soon as possible.

It's a pity that the original technology didn't expect the swordfish transport plane to be able to fly higher than birds, looking at the ridiculous "ammunition" that flew into the air and then stood still for a second and was pulled back to the ground by gravity, the elf Aroline couldn't help but laugh, and the sky opened a white flower visible to the naked eye, but none of them could touch the swordfish.

Soon the swordfish completed its task. In the hurricane-like fire of heavy blast guns, the support pillars of the three giant catapults collapsed, and many of the undead soldiers were smashed to pieces. And the swordfish, at the last moment when the fuel ran out, stopped steadily on the top of the dwarven tower. With the destruction of three catapults by the narrator, the morale of the dwarves has recovered considerably.

At the very least, you don't have to put up with skeletons that will fall at any time. The cavemen didn't attack in the middle of the night, but the apparently falling trees at the end of the plains proved that the cavemen were starting to build more giant catapults. Early the next morning, the narrator could no longer be found in the dwarf castle.
