The afterimage of the giant sword had not yet dissipated, and the heads of several monsters had been separated from their bodies, and hot steam was rising from the sections.

The man with the sword was none other than Felder, his blond hair hanging down, his head bowed silently, his face as calm as water, and the steel sword in his hand pointed directly at the corpses of several monsters.

"Wow, when did you get so powerful?" asked Eth, with wide eyes flashing. The others looked at Felder in amazement.

"Because I'm ......," the muscles on Felder's face quivered slightly, as if struggling to maintain his current expression. But before two seconds, he couldn't hold back any longer, grinned at the corners of his mouth, raised his head and laughed. The eyes were full of sympathy, and poor Felder was probably crazy.

It took a moment for Felder to stop, and he put his broadsword back into its scabbard in a dashing manner, and said loudly like a child who had done a good deed for fear that others would not know, "I finally understood the essence of the Force!" Probably laughing for a long time, the corners of his mouth twitched slightly, but his face was full of uncontrollable pride.

The Force, also known as the Primordial Force, is a primordial and violent force. The Force Conversion technique can be converted into the Force by consuming a large amount of stamina in an instant. Injecting the Force into oneself strengthens the body, increasing strength and speed, and infusing the weapon makes the weapon more powerful.

The Force is criticized for its rather low conversion rate. Although stamina is the basis for using the Force, the conversion rate is an unavoidable bottleneck, and the average Force user can only last for a few seconds when they use up all their stamina. There are only two ways to improve conversions, one is constant practice, and the other is talent, and Felder obviously falls into the latter category.

"Thank you, young man, I thought this old bone was going to be planted here. Old Neil laughed and raised his hand to pat Felder on the shoulder. The strength was so great that Felder couldn't help but secretly cry bitterly, feeling that his body was about to fall apart.

"Felder, you can't help but tell us!" Elena looked at Felder incredulously.

"No, that's what I just realized......" Felder scratched his hair embarrassedly.

......

"What's that?" Vane muttered to himself as he walked over to the corpses of several monsters and crouched down.

The monsters on the ground looked a bit like hunting dogs, but their skin was red and their hair was sparse. A slimy orange-red liquid flowed from the section of the neck, dripping on the ground and making a snorting sound. And there was a small piece of the monster's body that emitted a faint red light, alternating light and dark as if it were breathing.

"If it's a lava hellhound, it's a good thing in it, but watch out for the magma in its body. Old Neil said as he walked over to Vane, who put down his toolbox and pulled out a long black plier from it. The tip of the pincer was inserted into the body of the lava cerberus, and soon a small piece of something glowing with a dark red light was pinched out.

"Sure enough!" Old Neil exclaimed excitedly. He turned to Felder and said, "Boy, if you're lucky, I thought it would take some effort." ”

The little dark red thing was translucent, about the size of a pigeon's egg, like a glowing agate. According to Old Neil, this thing is called the Lava Core, which is a natural accelerant that works much better than ordinary accelerants, increasing the temperature of the furnace fire by several times. The accelerant itself does not burn, and when it has cooled completely, Old Neil pockets all six lava cores.

The group moved on, and Felder was at the forefront. There was more and more magma on both sides of the tunnel, and the orange-red light illuminated the mine, and the magic lamp in Simpson's hand seemed a little cumbersome. Everyone silently quickened their pace, and the scorching air was a little unbearable.

Before they knew it, they had come to the end of the alleyway, and in front of them was a vast space more than ten meters high, about the size of the central square of Obojar, with rough rock walls around it, which looked more like a naturally formed cave. Unknown magma becomes more unbridled here, slowly cascading down the rock face and converging together to form fiery pools.

"Where the hell is this damn magma coming from. Old Neil scolded as he walked. He lifted his foot and stepped over a pile of rusty parts and continued towards the middle of the cavern.

The dilapidated machinery was piled up haphazardly, and the scrap metal all over the ground seemed to have entered a garbage dump. Next to the dusty cooling pool, an old furnace was covered in rust, and the large felt was no longer smooth. Everything in front of you is embarrassing, and there is nothing more vicissitudes than this.

"Good machines have ruined these savage monkeys!" said old Neil, distressed.

"What is this?" Vane paused, crouching down and staring at the ground. There was a rectangular mark on the ground in front of him, about two fingers deep, that looked the size of half a chair, and the edges were blurred.

"Probably the imprint of some mechanical part. Old Neil said disapprovingly, after all, there are too many mechanical parts here. Was that so? Vane muttered to himself, but didn't say it—it wasn't the first time he'd seen such a mark.

Old Neil led the group through the "garbage heap", and soon a different kind of furnace came into view.

The furnace was about four or five meters high, and its surface was covered with dust, but it was visible from the outcrops that its surface was black. Scattered ore was scattered around the furnace, and a square cooling pool made of masonry had long since dried up.

"Get to work, boys, get rid of this garbage first!" said old Neil, who came to the furnace and was in high spirits as if by magic. After assigning jobs to each of them, he began to overhaul the furnace himself.

A few minutes later, a large area had been cleared out of front of the furnace by Wayne and the others, and the ground was fairly flat. Old Neil also repaired the furnace, which was dark and shiny around the door, and the inside was a silver-white inner wall.

"Ha, almost, this is a treasure!" Old Neil rubbed his hands together, his eyes shining, as if admiring a young girl.

As old Neil said, this huge melting pot can be said to be incomparably precious. Its outer shell is made of black iron, and the inner walls are bonded together with rare Mithril. Black iron is hard and durable, and Mithril is resistant to high temperature corrosion, and it can be said that the two materials complement each other well for the furnace.

But as the saying goes, Mithril is a thousand gold, black iron, and a thousand silver, although exaggerated, it is enough to show the preciousness of these two metals. If they hadn't seen it with their own eyes, I'm afraid no one would have believed that the dwarves had made a melting pot out of black iron and mythril.

Old Neil pulled out a large bag of sapphire magic stones from his bag and poured them through the door of the furnace with a clatter. Several pieces of Mithril were then put in, the largest of which was the size of a pigeon's egg.

"Old man, you're too picky, just put such a little bit of Mithril?" Felder teased.

"Boy, you're good at swordsmanship, but you're a layman at metal smelting. And, do you know how expensive Mithril is?!" Old Neil looked at Felder with disgust.

Then Old Neil added some black powder to the furnace, put the black ore and lava core into it, and finally placed the mold in the cooling pool.

"Bang!" the door was shut.

"It's on!" said Old Neil, turning on the furnace switch, and soon the inside of the furnace was burning fiercely. According to old Neil, it would be a little longer, and the others sat down in the open space to rest.

"Do you hear strange noises? It's like water boiling. Ace said suddenly.

Everyone said they didn't hear it, and the fire was blazing at this time, and the only thing in their ears was the sound of the wind whirring in the furnace.

"Eth, are you getting a little dizzy from the heat?" asked Simpson, concerned.

Ise shook her head, her face confused: "I'm not sure either, I can't hear it now." ”

"Don't you notice something strange?" Sweat was dripping from the tip of Vane's handsome nose, and his silky black hair was already wet. He frowned, and stood up with his sapphire staff in hand. "I heard from Grandpa Neil that this is the territory of the cavemen, but all the cavemen we saw along the way were burned to death. There are no signs of living activity here, except for the giant marks on the ground, I suspect ......"

Before Vane could finish speaking, a boiling sound suddenly sounded, and then, a roar like a landslide resounded throughout the mine.
