Although Aroth was also in the middle of actively developing its own brand of magic cars, the ones already racing at the forefront of this field were Helmuth’s dark-power cars.

These mechanical contraptions were a product of the magic engineering that Helmuth was so proud of, and they were also fueled by the dark power of the Demon King of Incarceration. Babel, the ninety-nine-story building that stood tall at the center of Pandemonium, served as a transmission tower, relaying the infinite dark power of the Demon King of Incarceration to the various sectors of Helmuth.

The Black Towers, which served as landmarks in the sectors of Helmuth, received and amplified the dark power sent to them by Babel, and relayed it throughout the entire city via magic cables buried underground.

The dark-power roads that were built like this, as the name suggested, had dark power flowing through them. The reason why Helmuth had been able to surpass all other countries on the continent in successfully commercializing automobiles was because the need for a magic engine to run their automobiles had been replaced by these dark-power roads.

Thanks to that, the dark-power cars didn’t need any fuel, and even humans without any knowledge of magic or mana were able to drive them.

“An essential course of tourism in Helmuth, the flower of all vacation trips! To all the tourists who have come to take part in the Demon King Tour, I bid you welcome!”

The wealthy and relaxed-appearing tourists who alighted from a huge tour bus were greeted by this grandiose welcome. The neatly dressed demonfolk guide who had gotten off before them wasn’t using anything like a microphone, but his magically amplified voice was still able to clearly reach the ears of all these tourists.

“The place where we have now arrived is the castle of the Demon King of Carnage. Among the five Demon Kings who lived three hundred years ago, the Demon King of Carnage was particularly tyrannical and ruthless. As his name suggests, this Demon King particularly enjoyed carnage…,” the guide paused to raise his finger and point to the hideous Demon King’s Castle behind him.

“Three hundred years ago, the heroes of the continent, led by the Great Vermouth, infiltrated the Castle. While the knights from the continent faced the Demon King’s army, Vermouth and the other heroes climbed up to the top floor of the castle and battled the Demon King of Carnage. Their battle lasted for three days and three nights….”

Even now, Eugene could still vividly recall the memories from back then.

That was the first Demon King they fought, and the first they defeated, but it wasn’t just the Demon King of Carnage who came close to death. An existence on the level of a Demon King wouldn’t die even if you killed them over and over again. They had cut off the head of the Demon King of Carnage dozens of times over those three days, but he still refused to die...
