The Lord Demon King is Unfathomable!

As for the more fundamental technologies, they were like heavenly scriptures to him, but these little rats used them with ease.

Looking at the goblin with a dumbfounded face, the mole people engineers from Iron Teeth City proudly said.

"Of course those dwarves don't have it!"

"Do those drunken thieves even qualify to compete with us?!"

"That's right! That group of dwarves can't even compare to a hair on our Lord Demon King's minions' legs!"

The hell dwarves nearby heard this and glared at them viciously, their teeth itching with hatred but not daring to say anything.

Not to mention that the real skills belonged to them, these fellows were personal servants brought by Lord Demon King, quite different from the goblin laborers at Black Wind Castle!

Kun Bu looked blankly at the skeletons nearby, and then at their legs.

There was a bit of moss, but not a single hair in sight...

As days passed, through the relentless efforts of the players, and after countless explosive experiments by the hell dwarf craftsmen and goblin engineers, the first magic crystal war machine of Black Wind Castle finally debuted two months after the hearing.

This war machine was entirely covered in jet-black steel armor, with wide and thick tracks crushing the workshop floor, emitting a resounding "click-clack".

This thing was like a colossal beast of hell that had slept for a hundred years, its trembling steam engine producing a hoarse growl! On top of its imposing steel armor, a gigantic magic crystal cannon stood tall, its muzzle faintly emitting a chilling gleam, like a beast ready to pounce!

Luo Yan was fairly satisfied with this creation.

With Iron Teeth City's technological strength, he could have made this thing even more perfect, for example by using Netherworld Language for the power system and getting rid of the cumbersome steam engine.

After all, economic factors shouldn't be considered for war weapons; practicality is the primary concern, and using demon crystals instead of coal is entirely acceptable.

However, Luo Yan didn't need to bring out all the good stuff at once; toothpaste can be squeezed out little by little.

Looking at the steel beast parked in the warehouse, a group of free testers chattered excitedly.

"Oh crap... you mean the old dude actually built this thing?!"

"This is totally lit, isn't it?!"

"Lit my ass! Isn't this just a piece of junk? The armor is still riveted, it'll be a joke on the battlefield!"

"You're comparing it to a modern tank?!"

"Come on, bro, giving it fair weight, I think this tech is better than a Mark I!"

"Nonsense! If you put a magic energy gun barrel on a Mark I, with undead crew members, I'd think it could spar with modern tanks!"

"You're right, but the Riemann Lusitan Tank is a main battle tank developed independently by the Terran Empire and deployed to the Astral Army, playing a crucial role in the great expedition..."

"Dude, what the hell are you talking about?! This is just a game! Why so serious?"

The excited chatter quickly went off-topic, but the players' excitement was genuine.

To help Lord Demon King's factory produce this thing, everyone resurrected twice on average!

Every piece of debris piled up in the workshop carries with it a past filled with blood and thunder.

The players gathered excitedly at the workshop entrance, all of them ready and eager to vie for the honor of being the first driver.

However, Luo Yan stood before the war machine and merely glanced at them lightly, then gently patted the shoulder of goblin factory manager Kun Bu.

"You are in charge of arranging the test driver."

"Ah? Okay, alright..."

Goblin factory manager Kun Bu wiped the sweat off his forehead, nodding repeatedly, then gathered a few of the most capable goblin engineers, climbing into the narrow confines of the vehicle with a spirit of heroic sacrifice.

There was no other option.

This thing left too strong an impression on them.

Even if nothing happened in the last few experiments, no one could guarantee they'd be that lucky next time.

Though the goblin engineers were trembling with fear, Luo Yan had no intention of changing his mind.

Precisely because "Hell's Flames" had so many issues, he couldn't let the players try it out.

Soon this tank was to undergo acceptance at the hearing, and he didn't want it to mess up at the critical moment.

Seeing the chance to show off slip away, the waiting players around were immediately vexed.

This critical plot was given to NPCs?

Does the damn developer even know how to make a game?!

"Lord Demon King, I've dedicated my life to researching this! Shouldn't I be the one to drive it to the Demon City for show?"

"This is unfair! I died a glorious 27 times! I even invented the 'battlefield mechanic' profession in the game!"

"Lord Demon King, please let me burn for you once more!"

"Big Dad!!! Take me with you!"

Looking at the players with faces filled with resentment, Luo Yan's lips subtly twitched upwards, his voice calm but resolute, like an NPC who didn't understand human language.

"You've already done very well."

He gently raised his hand, a wave of magical power flickering in the air as the crystal ball in his hand lit up.

"As a reward, you can witness this revolutionary military trial first-hand in soul state."

As he finished speaking, he cast a glance at Youyou on the side—he knew that fellow must be watching the show nearby.

Sure enough.

In just a second, the players' surroundings turned dark, and in a blink, their souls had detached from their bodies, becoming ghosts floating inside the crystal ball.

"Damn! Is this arrangement for real?"

"Am I still a ball? Why don't I even have a chat channel?!"
