A Lesson for This World

Rein and Tuster visited the Oma Royal Academy of Sciences today with the intention of causing trouble for the Dean, Breidan de Molay, and were already prepared for a major battle.

Therefore, long before they entered the academy, in a certain industry in Ymir, the nineteenth district closest to the academy's Mechanical City, eight hundred mech warriors from Black Dragon City were already ready to go.

They donned their mechs, prepared their ammunition and artillery, and awaited the order to attack.

At that very moment, a signal flare of Black Dragon Firework lit up the sky, and they received the message immediately.

"The city lord has given the signal: attack the city!"

"Yes, General!"

At a command, eight hundred mechs surged out of the streets like tigers unleashed from their cages, following the battle plan.

These eight hundred mechs were all painted with the Black Dragon City logo, looking majestic and imposing.

Although both are dark-style armors with golden antlers, their designs are not exactly the same.

Leading the charge were Shield Warrior Mech, their armor and boilers noticeably thicker than the others; behind them were artillerymen, their complex and precise firing systems resembling tanks. While not carrying many weapons, they had cannons of various calibers mounted on their arms and shoulders—truly devastating weapons with wide-area destructive power; there were also Machine Gunner equipped with "Sixteen-barreled Vulcan Cannon"; Light Armor Ghost Assassin Soldier; and finally, various functional mech engineers, Flamethrower Soldier, Demolition Soldier, and Armor-piercing Soldier.

This is a standard Mechanical Legion!

The technology and equipment on each mech are among the best in the world.

Their mechs only have two hands and two feet, unlike old Mr. Tuster who has eight Mechanical Arm and can control various complex weapon systems.

Fortunately, the large number of people and the well-matched professions meant that the legion of eight hundred warriors was equipped with almost all the functions required for war.

This was a top-tier Mechanical Legion that was absolutely terrifying in terms of combat power and unparalleled in terms of technology at the time!

"Clang, clang, clang."

The Mechanical Armor made a tremendous noise as it ran, with the sounds of Mechanical Skeleton rubbing together, gears grinding, and Steam Boilers gushing out, all blending together like a torrent surging into the city streets.

Eight hundred mechs were deployed in unison, like a torrent of steel, violently rushing into the sight of the people in the capital.

Each of the mechs, weighing several tons or tens of tons, stomped and spewed air, causing the entire block to tremble violently as if an earthquake had struck.

This scene shocked everyone in the 19th block.

"My God, someone actually dares to mobilize Mechanical Troops in the city, is this a rebellion?"

"Wait a minute, this isn't our Omar's Royal Mechanist."

"Look at that insignia, that's the Black Dragon City's Mechanist Legion!"

"."

The residents, upon seeing the black dragon emblem on the mech legion, immediately understood that these were the mechanics of Black Dragon City.

However, this also surprised them even more.

The law clearly stipulates that, apart from the City Guard, no one in the capital has the right to mobilize troops within the city.

If it occurs, does it mean Rebellion War?

"Is war about to break out?"

"We heard gunfire coming from the Royal Academy of Sciences just now. Could something have happened there?"

"Could it be a coup?"

"."

Terror was evident on everyone's face.

While everyone was still speculating, the Black Dragon Mechanical Legion opened fire!

"BOOM!"

"BOOM!"

"BOOM!"

"."

The city was filled with the sound of heavy artillery fire, and everyone realized that this was not just a mobilization, but the start of a real war.

The City Guard Army, originally sent by the Empress's Faction to monitor this contingent, had just formed a defensive line on the street to try and stop the Black Dragon Legion. But in an instant, they were swept away by that torrent of steel.

In terms of firepower and equipment, the two sides' forces are not even in the same league and there is no comparison whatsoever.

The number of people is also completely meaningless.

The eight hundred mechs of Black Dragon City were like a sharp blade rampaging through the belly of a giant beast, leaving no stone unturned and leaving rivers of blood in their wake.

Smoke and gunfire paved a smooth road straight to the Royal Academy.

The warriors of Black Dragon City worked in perfect unison, leaving no enemy standing a chance. Even Fourth Tier or fifth-tier Transcendent were instantly reduced to mincemeat by their sharp artillery fire and sliced into bloody pieces by their black blades.

This well-trained elite Black Dragon Army made the people of Omar, the "Mechanical Holy Land," experience for the first time the fear of being crushed by mechanical technology.

Only then did everyone realize that their proud steam technology had been mercilessly trampled underfoot!

"My God... That really is battle armor? Those mechanics from Black Dragon City are actually that strong?"

"This combat power is even stronger than the armor of our 'First Royal Mechanist'!"

"It's more than just powerful; it's on a completely different level! The individual combat strength of this Black Dragon Mech is no less than that of any Fourth Tier or fifth-tier Transcendent being. In a legion operation, even the 'Ten Great Legends' would be annihilated in a head-on confrontation."

"Look at the shields those mechs are holding; they don't even budge when hit by cannon fire?"

"That's 'Angelas Black Iron'! Unbelievable. There are actually people in the world who would be so extravagant as to use such a top-tier alchemical material to forge shields, and even give one to everyone? Damn it, could it be that Black Dragon City has discovered a super Godblood Ore?"

"The leader of that Black Dragon Legion, isn't that Storm General Baron? He was forced into Rebels by those noble lords back then, now this is going to be interesting."

"."

The intense sound of gunfire instantly echoed throughout the entire 19th block.

No, it spread like wildfire throughout the entire Imperial Capital Wussenbar through various channels!

The news reached the Oma Imperial Palace immediately.

Ymir listened to his subordinate's report without any surprise on his face.

She glanced at the unconscious Emperor Dopler Spurglin, sighed softly, and murmured, "Brother, Omar is truly rotten to the core. For this era, for human civilization, this ending might not be such a bad thing."

With that, Ymir rose and left, calmly accepting the sword handed to her by the maid and fastening it to her waist.

She stepped out of the room, gazing at the still-burning Black Dragon Firework in the sky, a sharp glint flashing in her azure eyes.

Then, he leaped off the city wall.

The Second Prince's Chamber.

"Where did the gunfire come from? Did my two younger brothers make their move first?"

"Your Highness, it's the Oma Royal! We just received news that a conflict has broken out between Black Dragon City and Dean Breidan, and a major battle has ensued. The city is currently under lockdown, and the situation is unclear. However, intelligence from the 19th District indicates that a very powerful Mechanical Legion has appeared and is heading towards the Royal Academy."

"What's the Empress's side of business?"

"The entire City Guard Third Legion, controlled by the Lopez Family, has been mobilized and is now stationed at the Royal Academy."

"Where are my two younger brothers?"

"Neither the Fourth Prince nor the Eighth Prince's men have made any unusual moves."

"Keep a close watch and report back immediately!"

"Yes!"

At almost the same time, all the Established Nobles in the city received the news.

But apart from a few individuals, the vast majority of people were unaware of the feud between Tuster and Breidan.

Hearing of the great battle raging in the capital, everyone was on edge, fearing a prince had launched a military coup. This even triggered a chain reaction, causing many hidden forces in the shadows of the capital to emerge. Suddenly, the entire capital was in turmoil, with signs of imminent chaos.

But not long after, confirmed news arrived.

Upon hearing that the attackers were actually from Black Dragon City, everyone was shocked and found it hard to believe.

It was common knowledge that Ymir had brought a mere eight hundred Mechanical Knight and two hundred dragon guards with her.

With such a small number of people, there's no way they could possibly make any waves in the capital.

They were also surprised. Were those guys from Black Dragon City crazy? How dare they cause trouble in the capital?

Everyone thought the situation would be quickly suppressed, but to their surprise, the fighting became increasingly fierce.

At the top of the tower of the Oma Academy.

The Fourth Prince Muller, was about to go down to help, but when he saw the black dragon in the sky that was clearly a lucky one, he hesitated.

People in his position have to think things through carefully before doing anything, and the most important thing is not to treat others as "fools".

But then, those guys from Black Dragon City made a choice that everyone considered "extremely foolish."

War in the capital?

The thousand guards that Ymir brought could be easily wiped out by any detachment of the city guard.

What are those guys thinking?

Muller watched the increasingly intense artillery fire in the distance, his brows furrowed and never relaxed.

At this time, intelligence reports came in like snowflakes.

"Fourth Prince, we have just received urgent intelligence: a Mechanical Legion from Black Dragon City has appeared in the 19th District and is heading towards the academy. The intelligence states that the Mechanical Legion is extremely powerful, with individual combat strength reaching at least the Fourth Tier of the Transcendent, or even stronger!"

How many people are there?

"Eight hundred."

"."

Upon hearing this information, Muller was not particularly surprised, but instead fell into deep thought.

When he saw the Tuster Eight-Armed Armor before, he guessed that Black Dragon City might already have a batch of top-level mechs.

Although he didn't want to see a strong opponent, things had come to this. The most important thing right now was to seize the Imperial Throne, and he would be happy if Black Dragon City could severely damage the Empress's Faction.

But that doesn't seem realistic.

This appears to be a conflict of "fighting against all odds."

It was the number eight hundred that puzzled him.

"Wait a minute, is this what my aunt is relying on? Even with eight hundred high-level mechs, they couldn't possibly breach the academy's walls. Where does their confidence to start a war come from?"

Oma Academy possesses the most robust Steel City Walls in the world, and the cannons on those walls are far superior to those of individual artillery.

In terms of both power and range, the city's City Defense Giant Cannon on the city walls are ten times, even a hundred times, greater than individual artillery!

After all, the range and power of artillery are directly related to its caliber and barrel length.

The mechs carry individual artillery pieces that are no more than two or three meters long, while the city walls have giant cannons that are tens or even hundreds of meters long. No matter how advanced the artillery technology is, at least in this Gunpowder Mechanical Era, one truth cannot be ignored.

More is beautiful, bigger is better, and caliber is justice!

Your firing range is only 100 meters, while the opponent's is 1,000 meters.

You can't destroy the city wall armor with one shot, but the enemy can easily wipe you out with one shot.

This gap gives you absolutely no chance; it could mean total annihilation in a matter of minutes.

Attacking a city with individual combat mechs will only result in total annihilation.

Even if there were 8,000 or 80,000 mechanics, let alone 800, the situation would be the same.

In Muller's mind, even the "legendary" Eight-Armed Armor would have no chance of surviving such a barrage of artillery fire.

In this era, siege warfare either involves breaking through from within or a head-on clash between Mechanical City.

It is almost impossible to Human Siege alone.

"Could they be hiding even more Wyvern Legion?"

At this moment, Muller suddenly looked up at the sky and guessed that Rein and his men might have brought more than two hundred Wyvern Legion.

But then he shook his head.

With the outbreak of war, the entire Oma Imperial Capital went on high alert. All kinds of Anti-aircraft Artillery and Anti-aircraft Gun were already aimed at the sky. Once the Wyvern Knight were spotted, under the overwhelming Firepower Net, any attempt to descend upon the Mechanical City would surely pay a heavy price.

This method also won't work.

But just as the thought arose, something unexpected happened.

Just as he was about to look away, he saw tiny black dots, the size of sesame seeds, appear in the sky.

"They really came?"

Muller was startled, his face showing surprise. But then he realized that the black dots weren't dragons at all, but rather strangely shaped bombs?

At that moment, he finally understood what Black Dragon City was up to!

Bombing from the air!

Muller was greatly alarmed.

At this moment, he finally understood what Black Dragon City's "trump card" was.

He hadn't thought of this before because there was no precedent for "Air Raid Tactics" in this day and age.

Today, people's understanding of gunpowder technology is limited to the use of firearms and cannons; the concept of Air-dropped Bomb is completely foreign to them.

Moreover, ordinary gunpowder would hardly cause any damage to the thick Steel City Walls of a city. To actually breach the walls with explosives, one would probably need to prepare thousands or even tens of thousands of tons of explosives.

Even with flying dragons, it would be impossible to send such a massive amount of medicine into the sky!

"Damn it, I should have realized this sooner! With such advanced mecha technology, their gunpowder technology must be just as impressive!"

Muller cursed inwardly, vaguely guessing that something bad was about to happen.

But at the same time, he also realized that his location was too close to the city wall!

The thought had barely formed in his mind when he was terrified. Without hesitation, he jumped off the tower and ran towards the shelter, yelling at his bewildered subordinates, "Idiots, what are you standing there for? Find cover!"

Looking at the "black raindrops" in the sky, Rein's eyes gleamed, and he murmured to himself, "The first air raid of this era."

Only he, as a time traveler, knew how important "Air Superiority" was.

In the early stages of various wars, large and small, almost no ground troops were involved. Top powers could completely destroy a country's military facilities simply by relying on air strikes.

It can be said that whoever controls the Air Superiority controls the initiative in the war.

And now, Black Dragon City has brought the first real air raid of this era.

Even though these people were on guard against the Wyvern Legion, who could have guessed that Rein had no intention of letting the Wyvern Legion physically attack the city?

High-altitude bombing is the best way to deal with the Mechanical City. Moreover, it's a siege tactic that the enemy simply cannot defend against, even if they find out about it.

Without the ability to destroy the Wyvern Legion in the air, the enemy can only watch helplessly.

Rein did bring more than two hundred Wyvern Legion this time, but the actual number was not that many.

Two hundred entered the city, and another five hundred were waiting outside the city.

Although the number was small, each of the five hundred Wyvern Riders carried an astonishing number of [Goblin Armor-Piercing Bomb] in their Storage Ring.

The precision bombing skills honed through secret training, combined with the extraordinary perception of the Transcendent and the goblin's high-powered binoculars, give this unit the precision of a "Laser-guided Bomb."

Five hundred Wyvern Riders were equivalent to five hundred bombers. They hovered high in the sky, unleashing a rain of bullets that symbolized impending death.

However, just a few breaths later, the Rain of Bombs from the sky had already fallen on the East City Gate of the Oma Royal.

This is the section of the city wall connecting to the Thirteenth District, heavily guarded by the city's defenders. It houses thousands of massive cannons, originally intended to obliterate any invading enemy.

Without the Mechanical City's siege, even if hundreds of thousands of troops came, they would all be reduced to ashes by these giant cannons.

But no one expected that the intelligence indicated the Black Dragon City's 800- Mechanist Legion was heading this way; however, before they could even see it, a dense rain of bombs began to fall from the sky.

Those giant cannons were completely useless and were engulfed in flames.

Boom!

Boom!

Boom!

A series of violent explosions rang out, as if the sky were falling and the earth were splitting apart.

Armor-piercing rounds penetrated the steel plates and exploded, shattering sections of the city wall's armor that were held together by rivets. The East City Gate of the Oma Academy instantly erupted into a dazzling sea of fire.

On this day, Black Dragon City used its then-unique Air Superiority to teach this era a lesson.

The concept of "air raid" was introduced to the world for the first time.
