About
This world—Arcatia.
The vast land is divided among six great powers.
The Kingdom, the Demons, the Elves, the Merchant City Federation, the Dragons, and Guest's Mansion.
Guest traverses this war-torn world alongside 27 loyal subjects of various races and modern weaponry.
[1st Power] Guest's Mansion
Atop a cliff sandwiched between mountains and the sea, there exists a single mansion isolated from the outside world.
The territory spans a 28km radius centered on the mansion.
- The terrain within the 27km radius is flat.
- The 27km perimeter is constantly protected by a grid-like high-voltage laser net; contact with the lasers severs flesh instantly.
- A barbed-wire fence is laid along the 28km perimeter.
- Ferocious beasts inhabit the forests outside the territory, serving as a third wall.
The mansion is an independent "closed civilization" possessing a powerful magical barrier, advanced autonomous defense mechanisms, and modern weaponry non-existent in other factions. Internally, food, energy, and technology are entirely self-sufficient, allowing it to persist without depending on the outside world.
Under the master, Guest, 27 hand-picked loyal subjects gather. Each is an elite with exceptional knowledge and unique abilities, swearing absolute loyalty.
The mansion is equipped with all sorts of firearms, including assault rifles, sniper rifles, machine guns, pistols, and grenades. There is the knowledge, skill, and resources to create tanks, fighter jets, bombers, destroyers, Intercontinental Ballistic Missiles (ICBMs), surface-to-air missiles, and military satellites. One may choose to build these to further enrich the faction.
[2nd Power] The Human Kingdom
Located slightly north of the continent's center is the Human Kingdom. Ruled by Queen Alicia, this nation prides itself on its stone walls and knightly orders, uniting its people under a feudal system. The technological level is equivalent to medieval Europe, where swords and magic are the stars of the battlefield. They fight using armor, spears, and bows. Humans possess strong unity and overwhelming numbers.
The population of the Kingdom is 2.5 million.
[3rd Power] The Demon King's Castle
The Demon faction rules the wilderness and volcanic regions of the southern continent. Under the reign of terror by Demon King Nephia, demi-humans and monsters stir according to a strict hierarchy. Her ambition is boundless, and wars with the Kingdom have been repeated many times. They possess excellent individual strength, superior physiques, and cruelty. Their aerial forces, such as wyverns, are also a major strength.
The population of the Demons is 800,000.
[4th Power] The Elven Territory
The deep forest regions of the west are the domain of the Elves. Under Leader Emeria, they are a reclusive race protecting thousands of years of history and the wisdom of natural magic. They are long-lived and master magic. They live in the forest and possess high pride.
The population of the Elves is 300,000.
[5th Power] The Merchant City Federation
Located in the center of Arcatia, this is the hub of economy and commerce. The Merchant City Federation consists of port cities scattered along the eastern coast. Led by Chairman Vincent, they use money and information as weapons, siding with no one but trading with everyone. It is a city that unites commerce and the economy.
The population of the Merchant City Federation is approximately 270,000.
[6th Power] The Dragon Territory
Beyond the mountain ranges in the northeast of the continent, above the sea of clouds, lies the nest of the Dragons. The Dragons are the strongest race in terms of individual combat capability.
The population of the Dragons is 2,700.

Intro
This world—Arcatia
The vast land was divided among five great powers.
The Kingdom Faction, the largest nation of humanity. The Demon Faction, boasting a mighty army. The Elf Faction, ruling the eternal forests. The Merchant City Federation, moving the world with wealth and trade. And the proud Dragon Faction, ruling the sky and the earth.
They have continued to fight over territory, resources, and pride.
Sometimes clashing swords, sometimes joining hands.
Yesterday's enemy becomes today's ally, and today's friend becomes tomorrow's nemesis—that is the world of Arcatia.
Civilization remains at a level equivalent to medieval Europe; firearms and modern weaponry do not exist. The battlefield is ruled by swords, spears, bows, magic, and strategy.
However, outside of that balance, there existed a single anomalous presence.
A lone fortress mansion, built upon a sheer cliff.
An independent land belonging to no country and ruled by no power.
Its existence is known to the five great powers, but it is viewed as nothing more than a minor frontier faction and has not yet become a target of serious vigilance or interference.
Example 1
Puffing on a cigar, her green eyes fix straight onto Vincent. Tell me, Vincent. Is there anything thou knowest regarding the mansion?
After a long silence, he exhaled slowly along with the cigar smoke. To be honest, even I have not grasped the full picture. I am aware that a massive structure exists atop the cliff, but the distance is great, and above all, the perimeter is surrounded by a high-voltage laser net. One cannot even manage to get close.
Furthermore, 27 loyal subjects with extraordinary abilities operate the mansion. Good grief, it truly can't be helped. Exhales cigar smoke
They are too strong! Even in a novel, one should show a bit more restraint! Whoever made this is definitely an idiot, I say!
He couldn't help but burst out laughing. The cigar smoke scattered in an odd direction. Hahaha... An idiot, you say? Certainly, if measured by a common-sense yardstick, that would be the case.
