The Lord Demon King is Unfathomable!

"Wait, did you just say a chat channel? Are we playing a game?"

"He's fooling you, sucker."

"@#%$!"

"Calm down! At least this time we weren't blown up, we were invited in!"

The noisy sounds were taken in by Luo Yan, as skeletons stood motionless like sculptures.

Luo Yan looked at Kun Bu beside him and gave instructions.

"Settle my servants' bodies well."

"Alright, alright!" Kun Bu quickly nodded, fearing he'd end up like those goblin engineers—stuffed into that man-eating hunk of metal's belly.

Luo Yan nodded and then picked up a Communication Stone capable of short-range voice transmission.

"Move out!"

The tank's engine roared, and the short, stubby smokestack spewed steam.

Accompanied by the tremors of the earth shaking, the load wheels entwined with tracks slowly turned, pushing the steel beast toward the wilderness outside Black Wind Castle, heading to the testing ground ten kilometers away...

Meanwhile, on the other side, at the testing ground in the outskirts of Demon City, the gray dome was as gloomy as if covered by dark clouds.

The military officers from the War Department and the bureaucrats from the Logistics Department had long been waiting at the testing ground, standing on the circular observation platform, overlooking the central tactical drill area paved with obsidian.

In the distance, a team of demon soldiers was adjusting the magic observation mirrors, while the clerks responsible for recording test data were flipping through documents, awaiting today's main event.

As the parliament-designated supervisor, Atlant Hephis stood with his hands behind his back, his eyes fixed in the distance, a faint flame burning in his deep pupils.

Suddenly, his brows twitched with a flicker of flame, and an intrigued expression surfaced in his eyes.

Although the Magic Crystal War Car waiting for inspection had not yet arrived on site, as a Diamond Level Flame Demon, he had already vaguely sensed a powerful force approaching.

And not far behind Atlant, Salman, the War Department staff officer, couldn't suppress his excitement. His arms were crossed on his chest, and his eyes occasionally scanned the surroundings.

Contrasted with their anticipation, the expression of Hakes, the Logistics Department undersecretary, was much more rigid.

His eyes flickered, his fingers rubbing nervously inside his sleeves, as if plotting something.

Just then, that low roaring sound finally drew near from afar, enveloped in billowing dust, arriving rapidly from the horizon.

Upon seeing the rolling dust on the distant horizon, Salman's eyes widened instantly, quickly raising the monocular in his hand, and he exclaimed with surprise.

"It's here!"

As his words fell, the steel behemoth coming from the direction of Black Wind Castle finally came into everyone's view.

That was the latest-innovated Magic Crystal War Car from Black Wind Castle!

That towering figure was like a fortress forged from steel, broad tracks crushing the rocks along the way, with an overwhelming sense of power, trampling on the fractured soil with its steel-cast foot.

Under the amazed gazes of everyone, this enormous war vehicle finally slowly drove into the testing ground, showcasing to the War Department and Logistics Department officials the crystallization of the Great Graveyard's Netherworld Language technology and steam-powered technology!

"...He really pulled it off." Mumbled Salman in a low voice beside Atlant, the excitement on his face growing more intense.

Especially when he saw that massive cannon!

The huge Magic Crystal Cannon was embedded atop that steel fortress, pointing far ahead!

Everything was just as Luo Yan had proclaimed—he endowed the Magic Crystal Cannon with mobility and defensiveness not inferior to the Abyssal War Beasts!

He indeed did it!

Standing behind Salman, several technical bureaucrats from the War Department whispered among themselves, exchanging the astonishment in each other's eyes.

It wasn't entirely that they were amazed by the Magic Crystal Cannon's caliber or that towering steel body; what truly astonished them was its form of movement!

The "rolling iron sheets and wheels" seemed devoid of any magic array assistance, and the massive chassis had no Demon Beast to pull it!

This mechanism seemingly relied entirely on its own driving force to move forward!

Some demons familiar with human society quickly recognized the steam spewing from that smokestack... this was undoubtedly the steam engine commonly seen in surface human society.

Yet the perplexing part was precisely here.

In their impression, this device was always used on ships!

It was the first time they saw a "smokestack" running on land!

The "Hell's Flames" Magic Crystal Tank halted on the empty training ground.

Luo Yan jumped down from the armor and leisurely walked to the side of the observation stand.

Looking at the gathered officials from the War Department and the Logistics Department, he said with a smile.

"Delayed a bit on the road, hope I haven't kept you waiting too long."

Unable to contain his inner excitement, Salman couldn't help but leave the observation stand, stepping quickly forward, his gaze fixated on the tank's tracks below and asked.

"What's the principle behind this?! Why do a few pieces of steel... enable such heavy armor to move?!"

"This is the war equipment I described to you." Luo Yan smiled slightly, his gaze calm, "It runs on coal, with a top speed of 10 kilometers per hour. Though not as fast as a steed, it possesses autonomous mobility and can advance on muddy, rugged terrains, just like I demonstrated earlier."

Generally speaking, he wouldn't recommend driving a tank across the wilderness; the correct use is to tow it to the site and then deploy it.
