It was only when he actually stepped into the city that he felt small. Compared to the underground city, Kyoto City and Manning City are nothing more than a pile of stone toys.

Legend has it that dwarves are not tall in stature, rarely exceeding one gram, but they are infinitely powerful, and their small bodies can burst out with the power of mountains.

Wandering through the quiet streets of the Black Iron City, the stone houses on both sides are all closed doors and windows, without a trace of light. The streets still retain their former structures, and some of the shop signs have long since decayed and fallen in front of their doors, and have been shattered into iron filings over time (Note 1).

"What's wrong with this city?" said Koster, looking at the uninhabited houses on either side, a little sad.

"Nobody knows. "There aren't many records in history, and I heard the elders say that the entire dwarven clan was forcibly relocated by the Magic Empire, and they left in a hurry, and the black iron ore that could not be moved was abandoned at that time, and many of the tools that had been formed were abandoned, and the Great Elf King probably knew the situation at that time." ”

The group walked along the streets of Black Iron City, stepped on the bridge over the lava river, and reached the main entrance of the Dwarven Palace, and through the palace, they reached the smelter. In the culture of the dwarves, smelting and forging are the skills in their bones, so the smelter is built directly behind the palace, and in the eyes of the dwarves, there is nothing to disobey.

Standing in front of the main entrance of the royal palace, looking up at the statues of two dwarven warriors. At the foot of the statue, there is also a metal nameplate, which is supposed to introduce the lives of these two dwarven warriors, but the tadpole-like dwarven text on the nameplate has long been lost, and several people present can't understand it.

Walking into the throne hall, Ficcio walked into the darkness by the door, and after a while, there was actually a fire dragon, along the entire throne hall, ignited.

"Don't be surprised, there is a fire ditch here, and in it is the fat of an animal from the long sea, which does not rot for ten thousand years, and when we first came, we found that it could be ignited. Ficchio explained.

The lit fire illuminated the throne hall of the Dwarven Palace, a small circular palace, surrounded by seven statues above the fire ditch, and the statue in the middle was a little familiar, and it was a miniature version of the huge dwarven statue at the gate of the Black Iron City. At its feet, a black iron chair with an all-black body sits there quietly.

The shape of the black chair is quite peculiar, the low body of the chair seems to be tailor-made for the dwarf king, and the high back of the chair reflects the supreme dignity of the dwarf king.

Feida and Xiao Han looked around at the statues, "Captain, who are the dwarves of these statues?"

"These are the seven wise and great kings of the legendary dwarf kingdom, and the one in the middle is also at the gate of the main city. ”

Kester looked at the statues of these kings with fascination, imagining the once powerful dwarven ancestors.

Ficcio didn't let the crowd continue to watch, but urged to move on. The passage to leave is behind the throne, flanked by a small door on each side of the McKinney Bronze Hammer statue. Everyone entered through the door on the left, then passed through a long dark road, and after a few dozen steps, turned another wall, and Kerst suddenly noticed that his eyes lit up.

"I'll go, what a pool of magma!" Kerster's exclamation echoed over the Black Iron City. It's no wonder that Kester reacted so much, it was obscured by the palace from a distance, and behind this, the lava rivers of the Black Iron City converged here, forming a lake of magma, and the red magma sprayed hot gas, tumbling magma bubbles, and throwing waves of heat into the air.

A stony roadbed, deep into the magma pool, the magma washes the outer wall of the roadbed but cannot be shaken in the slightest. The stone path leads to the opposite shore of the magma lake, in the center of which there is a small platform, and on the opposite side of the stone path, a magnificent all-black gate, tightly closed.

On the platform of the stone road, a bronze bell is hung, and at the top of the bronze bell, a series of precision gears form a set of linkage devices, and at the other end, a "water wheel" is connected. The waterwheel is still running slowly, seemingly every once in a while, and then drives the copper hammer of the copper bell to ring the copper bell fiercely.

"That's how the bell came from!" Kerst suddenly realized.

"This bronze bell should be the symbol of the city, those dwarves should have followed the bell back then. Feida said from the side.

Without further ado, the group walked along the stone path to the other side of the lava lake, where there was a closed black gate.

Walking to the door, Ficcio had not yet spoken, the anxious Khster was the first to step forward and knocked on the door, and a pain came from the palm of his hand, "Ouch", Caster exclaimed in pain, "Black iron." ”

"Of course, it's Black Iron, it's called Black Iron City, and most of it is probably because of this iconic smelter gate. Ficchio explained to Xter.

Caster rolled his eyes, meaning that the all-metal door was now closed, what should I do? Ficcio did not answer, but walked to the door, and only then did Chester notice that there was a black iron rod more than a man high on the ground, standing there. Kerst stepped forward, and together with Ficcio, he pulled the black iron rod with all his strength, and only then did he hear a creaking sound, and the closed black iron door slowly opened a crack.

"It's open!" Feida and Xiaohan cheered on the side, and Chester wiped the sweat from his face, saying in his heart, no wonder the dwarves in the legend are infinitely powerful, and it is so difficult to even pull such a door hand in hand. Everyone squeezed through the crack in the black iron door and found that the smelter was completely black, and Ficcio's lantern could only illuminate a small patch.

"In the past, when the smelter was still working, the magma from the outside would flow into the smelter through special pipes, and those black iron ore, copper ore and even precious silver ore would be smelted into molten iron and copper under the heating of natural lava, and then made into various weapons and utensils by the dwarves. With the disappearance of the dwarves, those magma can only stay quietly in the lake outside, which is why this smelter seems so deserted. ”

"In that case, how can we find what we are looking for?" said Kerth, tilting his head, in thought.

Ficcio laughed, "Don't worry, you're not the first to come here, come with me." ”

Along the way, Kest saw many workbenches, floors or walls, there were many stone molds, and there were still some cooled metal left in the molds, and it seemed that the dwarves had evacuated in a hurry. Ficchio led the group to the depths of the smelter, where there were dozens of smaller black iron doors, some of which were already open, and many more were still closed.

Ficcio came to the door, there were some torches by the door, he lit a few torches, and then handed them to everyone, "This is the temporary warehouse of the dwarven smelter, at the earliest, we found all kinds of ores and shaped weapons left by the dwarves here, this is the destination I brought you here this time." ”

"Roar!" said Koster, who took the torch and was the first to burrow into an open black iron door.

Inside the door was a storage room, most of which had been emptied, only on the innermost wall, a dozen wooden boxes were stacked, and Kerst lifted the lid of one of the boxes, reached in and dug it out, feeling that he had touched something, and took out a piece, which was a formed black iron ingot.

In several other boxes, there are also molded black iron ingots. Black iron ingots, which have been smelted, are smelted into bricks for easy storage, and the next time you need to use them, you only need to heat and melt them and then recast them.

Kester walked out of the warehouse to the next one with an open door, and rummaged for a while for the same few metal ingots that remained, but this one was all copper ingots.

There were several rooms, all of which were metal ingots of various kinds, until the last warehouse in the row had opened its door. The warehouse was smaller, only one-third the size of the front, with three or four small wooden boxes scattered around. Koster lifted the lid of the box, and a dazzling light brightened Koster's eyes, "Oh my God, so much silver!"

In the box, there were neatly stacked pieces of silver ingots, and looking at the number, there were more than 100 pieces in one box. You must know that Thur silver is a rare mineral, like your own "broken heart" sword, which is a product of Tseyin. The Thur silver here is estimated to be all the savings of the dwarves for hundreds of years.

"I'm surprised!" Ficcio's voice came from behind him, "These Thurs should be worth a lot of money in your human world." ”

Kester thought so, but he didn't understand it either: "Don't you take so much silver?"

"I took it, but I didn't take that much, only a few. We elves, even if we take some, will feel guilty. So except for what was necessary, the rest was left in its place. ”

Kerst said that the elves were really strange, and he couldn't be polite, so he quickly picked up two silver ingots and stuffed them into his clothes. Well, give Xiao Mu a long sword, give Lolita a silver magic weapon, and give Liana a silver headdress, Feida's she takes it herself, Kerst counted it in his heart.

Looking at Kerster's movements, Ficcio couldn't help but wonder, sure enough, it was human. "Alright, Koster, let's follow, Feida and Xiaohan have already gone to the front. ”

"Oh, good. As he spoke, Koster fished out another silver ingot.

Feida and Xiaohan, in front of the closed warehouse opposite, they had already opened a black iron door, and Chester ran over quickly, and saw Feida and Xiaohan, standing in front of a wall with torches, their mouths wide open, speechless in shock.

"What's wrong, what's wrong! what do you see?" asked Kerst aloud as he entered the house. Feida didn't speak, Xiao Han slowly turned around, stretched out his hand and pointed at the wall.

Only then did Koster notice, and when he looked up, "Oh my God!" Koster was just as stunned as the two girls.

Ficcio walked in from behind him with a smile, "Well, it's exciting." When I first came, I was just like you!"

Note 1: The dwarves' signboards are all metal, so they can survive a thousand years after being abandoned.
