Reincarnated as the Demon King's Son

Other than The Mechanicum, there were other major underworld organization. An organization would only considered major if they could at least control one Dark City. These organization were Anarchy, Ash Corps, Virus Undetected, and Automatic Sinner.

Each of them controlled one or more dark city and could ask for 'tax' however they wanted in these Dark Cities. The catch was they had to defend it and protect it if they wanted to make profit. If people were getting robbed and attacked constantly, people would stay away from their cities.

Naturally, no sane criminals would dare to attack anyone in these mafia controlled cities.

But these organizations were nothing when compared to The Mechanicum who had 10 Dark Cities under their rule. The 4 of them had to work together and even by doing that they barely able to contend against The mechanicum.

The Mechanicum did not wanted their cities, if they do, they would have destroyed these four long ago.

But now that they had 'proper' reason to do so, they began to send out their legion.

All over the underworld, huge, mechanical worms dug through the land and breached the defensive perimeters of the city.

A man was walking in a dark city after transporting an illegal item. It was business as usual, but suddenly, the whole world shook which shocked the man since the city was supposed to be earthquake-proof.

But then, a giant mechanical worm burst out of the wall and opened its mouth wide, retracting the spinning teeth of which tens of thousands mechanical army began to flood into the city.

"An attack! The Mechanicum is attacking this city! Run for your life!"

"Why is the Mechanicum attacking the city?" a man asked despite the chaos."

"Who fucking care! RUN!"

The Mechanicum had never attacked other cities before. If they wanted something, they usually threatened the ruler directly, using intimidation and negotiation. They rarely used massive-offense operation such as this. But when they do—it created great chaos.

Buildings exploded left and right, the ground under their feet cracked, and lava spewed out from below and above.

Luckily, the Mechanicum already gave enough time for the people to flee the city before the mechanical legion fired their plasma beam at the buildings, leveling them into dust and rubbles.

Thousands of people in vest came out of a bunker and retaliated, but small drones from above obliterated them before they could even fire a single shot.

The drones swiftly flew inside the bunker, firing plasma beam at every living being they found.

Axtin, the leader of Anarchy was sitting in his office inside the bunker. His room was currently shaking and dust fell of from the ceiling. Lights flickering which made him worried that the enemy could come in at any time.

The screen in front of him showed how the Mechanicum destroyed his city. Gritting his teeth, he pressed a red button below his table and a projection of the other leaders appeared.

"Two of cities are under attack by the Mechanicum. All of you have to help me." As he said that however, he noticed that their expression were not good either.

"Our cities are under attack as well. As we are speaking, tens of thousands robots are rolling through my defenses."

Axtin pressed another button and a bunch of projection appeared, showing their cities being attacked by the Mechanicum.

The Ash Corps sent their powerful giant robots, but it was destroyed within a few minutes by the Mechanicum's far larger robot.

"My team has attacked as well, but they cannot do anything," the leader of Virus Undetected said. "Instead, our networks got attacked and some of our information even got stolen."

"Stop the attack," Axtin said. "We have to attack them physically."

"Can't you see? We are losing in the informational realm and the physical realm as well," the leader of Automatic Sinner said.

"We have to do something. We can't be destroyed just like this."

Suddenly, Axtin's ceiling fell. Smoke and dust filled the room which made him cough.

When he opened his eyes, he saw two pair of lights staring at him as it approached, revealing a three meter tall human in thick armor.

"You… you are the Supreme Warrior!"

"No. I am simply a Super Warrior. A Supreme Warrior is too much to take you out."

"Are you going to kill me? You cannot do this. Tell your boss that we are willing to serve."

"The order is to kill all and destroy all. No negotiation."

"NO WAIT!"

SLASH!

The other 3 leaders panicked and immediately turned off their projections. They stood and immediately activated their emergency protocols to escape, but before they could do that, they were greeted by a Super Warrior.

Tarrar and the Tech Priest were standing in a dimly lit room with a bunch of projections showing the scene of destruction of various underworld cities.

Tarrar saw an army of ten thousand being incinerated by 10 meter tall robot who could shoot flame thrower and sent rockets in any direction.

There were 30 meter tall robots as well with large cannons as their arms. Every shot was so heavy and so explosive that it destroyed 5 buildings per shot.

Small drones in the air, and dog like robots on land were on the move as well. There so many things that happened, but it wasn't chaos on this side as everything was perfectly planned and instrumented.

Tarrar was impressed by the Mechanicum's careful and perfect planning, and its variety of forces. There were small robot units, big robot units, and huge robot units, and there were even super human warriors.

There were so many robots for all kinds of specific task such as communication, information gathering, defense penetration, and so much more.

Tarrar was amazed how the Mechanicum could keep with all of these things. An army usually consisted of soldiers with different group assigned to a couple of basic task. But the Mechanicum made warfare seemed much more complicated than it seemed.

But Tarrar was sure that if he fought the Mechanicum, he would lose. Though he was confidence in his ability as a general, he better of managing cities and companies.

Tarrar looked at the Tech Priest. He had talked to him before and knew that his name was Corduul Thassentoth.

He was the Lead Tech Priest of the Mechanicum. Judging by his character and the value he could bring, Tarrar could say he would become a key subordinates for Aldred.

Especially since the idea of mixing technology with magic was even more likely now. Tarrar had heard that Aldred wanted to go to other continent.

He was sure that with Aldred's ambition, he would wanted to carve some land for himself. And for that he would need an army and resources to keep that army strong and growing.

Tarrar believed he could bring enough wealth for Aldred, but to grow his army…

That would be Corduul's task.

Tarrar approached him and tapped him in the waist.

Corduul looked at him.

"I am looking forward to be working with you from now on."

Corduul did not know the hidden meaning, but he shook the man's hand nonetheless.

Tarrar was known to be Aldred's Wealth Generator.

But Corduul will become Aldred's—

War Engine.
