The Lord Demon King is Unfathomable!

Unlike those slave rats, who not only die easily but also often turn into undead that indiscriminately attack everyone.

"Even if you say those guys are easy to use, we don't have a place to put them here."

"Exactly, exactly!"

Watching the skeleton soldiers discussing, the Black-iron Skeleton Soldier pondered for a long time, the soul fire in its skull flickering as it tapped its fist into its palm.

"How about this, since you're good at managing those ratmen and goblins, why don't you just manage them for us."

Brown Beard was stunned for a few seconds and asked in confusion.

"Do you mean we should send miners here? If you're willing to provide alcohol and food, then it's not a problem..."

As soon as he finished speaking, a skeleton soldier beside him immediately said.

"No need to trouble, we can directly mine over there with you, here we have to worry about that production safety law."

"Exactly, exactly! Mining here doesn't make much money!"

"That's right! We even have to pay you wages—"

Before he could finish speaking, his mouth was covered by other undead nearby.

The lead Black-iron Skeleton Soldier let out a creaky laugh, rubbed its hands, and continued speaking to the bewildered Brown Beard.

"Don't listen to his nonsense! Of course, we'll pay you, and how you pay those miners is your business, we aren't interested."

Brown Beard rubbed the back of his head and spoke.

"So you want to buy the ore we have?"

"Yes and no," the Black-iron Skeleton Soldier shook its skull and continued, "Your output is too low, I can guess with my toes how much that is, it's not even in the same league compared to our consumption."

Before the dwarf could argue, he continued.

"But that's okay! We can help you upgrade your mines! From large mine carts that can carry hundreds or even thousands of tons of ore at once, to small pneumatic drills, hand-held rock drills, chain cutters, these individual equipments will ensure that your current mine output can increase dozens of times! By then, our problem is solved, and so is yours, isn't that wonderful?"

Actually, the Great Graveyard doesn't have these mining tools either, but that doesn't stop him from painting this picture first.

Brown Beard was left stunned by this guy's words. Although he didn't fully understand what those tools were for, he understood the first and last parts of the message.

The undead of the Great Graveyard are willing to share such mine carts that can transport hundreds of tons of ore at a time with them!

These things can make the output of the Catastrophe Castle's mines multiply dozens of times!

His face instantly turned red, excitedly gripping the skeleton soldier's shoulder, no longer minding the eerie skeleton.

"You're willing to teach us this technology?! Really?!"

Not afraid of ghosts when you're dead: "Of course! Why not?"

I'll form the lower part: "Exactly, exactly! We can even help you build a railway from the Catastrophe Castle to the Great Graveyard for free!"

I'll form the upper part: "Then all you need to do is give us a few mines!"

Several skeletons' eyes glowed green, eager for the dwarf to agree immediately so they could start work tomorrow.

The various ores produced by the Great Graveyard used to be so abundant that they couldn't use them all, but now the situation has reversed, as since Beifeng City was established, a large number of Life Professions Kings have flooded into various industries, and the basic raw materials instantly became in short supply, to the point that some wealthy business owners even paid with RMB on the official website.

Although Beifeng Mountain has quite a few mineral resources, relying solely on players to mine them is definitely not enough to meet the growing demand.

It just happens to hear from the dwarf that the Catastrophe Castle has a large number of slaves and ready-to-use mines, so why not export some outdated technology to them and let them make use of those rats.

Seeing these undead so enthusiastic, Brown Beard was also excited in his heart, and his palms couldn't help but sweat.

Especially when he thought about the Great Graveyard's steel production being so lavish that they could pave roads with steel ingots, he was even more speechless with excitement.

Perhaps they could offer Goron Steel Bone a true steel throne, or simply build him a fortress with steel!

However, at this moment, he suddenly remembered the experience of several blackouts in the mine tunnel before, and suddenly felt as if a bucket of cold water had been poured over him, calming him down.

"But... we need to breathe in the mine, you guys are okay with all that smoke, but we can't take it." Brown Beard said with a troubled expression.

Unlike water pumps, the smoke produced by those steam engines is in fixed locations, so it's easy to vent it out.

However, these mine carts puff out smoke as they run, and it won't be long before the whole mine tunnel is filled with smoke.

Even if they don't care about the slaves' lives, they have to consider that their dead bodies might become undead, and the safety of the overseers is also very important.

But although the Hell Dwarves were full of concerns, these issues were just minor problems for the Great Graveyard.

The Black-iron Skeleton Soldier laughed and said.

"No problem! Such small things can all be solved in the design, like separating transport tunnels from mining tunnels, and designing ventilation shafts in the tunnels, we don't do it because we don't need it, if you need it we'll arrange it for you!"

Unexpectedly, these generous friends even considered these problems for him, Brown Beard felt both touched and deeply ashamed.
