Chapter 236: I Have the Illusion of Working in an Electronics Factory During the Summer Vacation

At the border of the rock cave where the Obsidian City is located, Carl and others looked at the direction of the cave called the exit and were speechless for a while.

Around the cave entrance, a group of fire dwarves who looked a bit like dwarves but whose beards and hair were all flames were guarding there.

Judging from the number, these guys are at least several thousand in size.

They have built a fortress around it and sent people to guard the fortress walls.

The crossbows enchanted with fire were arranged on the walls at a scale no less than that of the bastion base. The soldiers guarding the walls were all wearing heavy iron pagoda armor that only exposed their eyes and mouths, which looked difficult to deal with.

"Is this normal?"

Hiding behind a rock mountain a few kilometers away from the target, Carl put down the telescope and questioned the newly joined drow.

What the other party said before was: the passage to the surface was guarded by monsters sent by the fire giants.

The situation of the fire dwarves did not match their description at all.

"I, we didn't know it was like this! Those who escaped before became slaves with lower status than us after returning, and were sent to the plane of fire to do hard labor. We don't know the specific situation here."

Looking at the fire dwarves who were armed to the teeth, the drow mage complained with a trembling voice.

After a short silence, Carl regained his spirits and waved to Thorin.

"It's impossible to leave immediately. Next, let's prepare to build a temporary base here. I hope these fire dwarves have no direct way to contact the fire giants."

Sitting down against the rock like a resigned person, Carl looked up and thought about how to deal with those fire dwarves.

He was not worried about Mooreban, because V and Carl's spiritual connection was quite wonderful. Once Carl died, V would immediately respond.

At this time, Carl couldn't help but feel a little annoyed at the specialness of his world.

People's short message technique of Feren can contact familiar people as long as they are in this plane, and even if they cross planes, they are at most likely to lose the target.

Although Eberron also has short messaging, due to the interference of the twelve moons, the message loss rate is frighteningly high. Only the Scribe Dragonmark Family can use the dragonmark wonders made of Siberys dragon crystal to communicate stably.

Thinking of this, Carl shook his head and drove his unrealistic thoughts out of his mind.

‘Although Faerun is good, the gods fight each other too frequently. People like me may be affected by some disaster when I sleep in the middle of the night. Alas, it’s not easy! ’

With a slight sigh, Carl stood up from the stone of the rock mountain and prepared to start working with Thorin.

Relying on themselves to fight nearly three thousand fire dwarves, that is not a breakout, that is suicide.

“What are you going to do?”

Seeing Carl waving at him, Thorin stepped forward and asked Carl for his opinion.

He knew that he was not as good as Carl in forging technology or anything else, so he had always regarded himself as Carl’s deputy.

But as the saying goes, a good cook cannot cook without rice. What can the two of them do in this place where no one is shitting?

As if seeing Thorin's thoughts, Carl patted his shoulder.

"Don't worry, there is lava everywhere here, are you still afraid that we don't have materials? Maybe the lava can be refined into gold or mithril. Let's build an engineering construct first, and build a temporary base nearby for the others!"

At this point, Carl's consciousness was a little dazed.

'Why am I digging holes everywhere like a rabbit? After I become a mechanic at level 14, I must find a way to keep a demiplane fixed on my body! '

Just like the huge demiplane can be fixed inside the wizard tower, the caster can also keep the demiplane fixed on himself through certain means.

Carl's current theory on this is still at the level of borrowing from Mordenkainen's mansion.

"Hand-made an engineering construct? Just the two of us?"

Thorin asked in disbelief after looking around.

"What else?"

Pulling out a smile without any smile, Carl shrugged helplessly.

A few hours later, Carl made handy tools and started forging from the skeleton of the construct.

However, the others were not idle either. Scorpion and Bain took the newly joined drow to scout the enemy, Shadow was on guard, and Hope used the druid's ability to explore the nearby lava river and tried to dig some high-quality ore back.

With the lava river, smelting and forging are much more convenient.

In addition, Carl would study the relevant principles of the teleportation array in the dream world after sleeping every day.

After realizing that it was impossible to return to Storm Bay as soon as possible, his enthusiasm for studying the relevant principles increased a lot.

However, the remaining page of the giant spellbook also helped Carl to a certain extent.

According to Carl's own interpretation, he suspected that the spells recorded on this remaining page had a certain connection with space.

Because he recognized the runes related to the etheric world and the astral world in it.

Three days passed in a flash, and soon, an engineering construct that had shrunk several times was created by Carl.

It's not that Carl and Thorin don't want to build a bigger one, it's just that they don't have that much material left.

"Very good, let's dig a temporary base here!"

Operating this construct without a spirit, Carl provided his own magic power and began to dig in the nearby rock.

In order to prevent accidental digging into the lava river, Karl also brought a miniature floating cannon equipped with freezing rays.

Karl crushed the excavated rocks, threw them into a large crucible, and then placed them in the magma to heat.

Most of these rocks contain metal components. According to the information obtained by Scorpion and other drow, the fire dwarves also processed metal in this way.

This made Karl, who originally hoped to find a stable mineral source, a little crazy.

But he also made some improvements to the process.

That is to use the sulfur dioxide gas emitted from the lava to create sulfuric acid, then use strong acid to dissolve metals, and then reduce them through electrolysis.

The two methods were carried out at the same time, which allowed Karl and the others to make metal much faster.

But because the scale cannot increase, the total manufacturing volume is still somewhat small.

"Should we consider digging a tunnel directly from the nearby rock wall to the surface?"

Tortured by the iron smelting job, Hope tried to use her brain to come up with a less troublesome solution.

But Karl said to Hope very bluntly: "Do you remember how long it took us to land when we first fell? If we had to dig this distance by ourselves, we might have to dig for two years."

"Then if we can bypass the fire dwarf's fortress and enter the natural tunnel from another location, will it save a lot of time?"

Hearing this method, Karl hesitated for a moment, and then nodded.

"Hi~! This is a solution. Although it is still a bit troublesome, it is still a way out! Wait a minute, I will calculate the amount of work!"

Quickly taking out a piece of draft paper and laying it on the structure, Karl calculated for a moment and found that the amount of work was still bearable.

"You can't tell, Hope, your IQ has increased!"

"Hmph! Virtue~"

After giving Carl a punch, Hope walked briskly to prepare the food.

‘It’s best not to use too many constructs for this kind of secretive project. Three should be enough. ’

With this in mind, Karl glanced at the processed metal ingots and already had some calculations in his mind.

Controlling the construct to drill into the ground, Karl looked at the simple hole and sighed habitually.

After walking deeper for a while, a more spacious space appeared.

At this time, Thorin is building an assembly line here to produce construct parts.

Eight drow soldiers helped carry the materials, and it looked like a small workshop.

"How about it, are there enough metal ingots?"

Because the types of metals mixed in the rocks are different, the metals obtained by Karl and others are not completely consistent.

Most of it is iron, but there is still copper or other temporarily unidentifiable substances doped in it.

Using the method of different melting points of various metals, Karl tried to separate them, but except for iron and copper, the separation effect of other metals was good or bad.

"The strength of these iron ingots may not be up to standard. The air here contains too much sulfur, which causes the metal ingots to be doped with a certain amount of sulfur during the production process."

Seeing Karl come in, Thorin stopped what he was doing and reported the problem to Karl.

"Then don't worry about it for now. I'll think of a way later. You first use copper ingots to make a construct. Hope gave me an idea. I plan to..."

After explaining what Hope had just done, Thorin immediately supported:

"Okay! I think it's almost doable! But the iron structures still have to be made. Then we can use them to attack the fire dwarves, so that we can pass through the tunnel secretly!"

After reaching an initial consensus with Thorin, Karl discussed it with Bain and others.

In the end, the method proposed by Hope won the support of the majority of people.

The only one who had some opinions was Scorpion. This guy still felt that it was safer to use the construct to eliminate the fire dwarves head-on.

If they can contact other elemental creatures in the tunnel, they might catch up from behind as Karl and others advance.

That would greatly increase the danger Karl and the others would face.

However, what makes the fire dwarves troublesome for Karl is their fortress. If this difficult bone can be bypassed, Karl's mecha is enough to drink a pot of those iron cans.

The giant mecha can crush them with one kick.

After a little consideration, Karl decided to take a two-pronged approach. While creating the secret passage, they would also continue to create constructs!

Everything is difficult at the beginning. After Thorin set up the assembly line, Carl and the others started to increase the speed of construct construction.

As the number of constructs increased, the speed at which they smelted metal also began to increase.

However, there are always some tasks that need to be performed by the caster personally, such as those involving magic inscriptions and the creation of the construct itself.

A magic circle for summoning spirits was set up in another room. Everyone was like parts on a machine, interlocking with each other and running quickly.

This gave Carl the illusion that he was working as a summer job on the assembly line of an electronics factory.
