More than 2,000 years ago, the Demon Wars were an unprecedented unity in the history of Olopa, where all races and nations put aside past prejudices and disputes, and joined forces to fight a common enemy: the demon army under the command of the demon Satan Abaddon.

After more than eight years of fighting and paying a terrible price, the coalition expelled the demons from the land of Olopa. In order to prevent the demons from having a chance to take root and make a comeback in the present world, under the leadership of 12 heroes, the coalition army attacked the demon continent, the first stronghold of the demon in the present world, and appeared out of thin air on the surface of the Western Ocean.

After another year and a half of brutal bloody battles, 12 heroes fell one by one, and more than half of the Demon Slayer Coalition was lost, but they succeeded in driving Abaddon and his demon legion back to another dimension called the Demon Domain, and used the Star Key to permanently seal the connection between the present world and the Demon Domain. At this point, the vigorous demon war finally came to an end after ten years, leaving a glorious chapter in the history of Olopa.

However, the existing contradictions and strife were only temporarily shelved under the threat of the demon legions, and did not disappear because of the disappearance of the demons, and when the common enemy was defeated, they gradually surfaced.

Although the remnants of demons and the Force pools are still scattered throughout the three continents of Olopa, posing a serious threat to the inhabitants of the continent, the war of mutual annexation within humanity has long begun. Among them, the most powerful is the Thumiro Empire, which is also feared by the Central Church. This new empire, which had risen rapidly during the Demon War, enjoyed the largest share of the war dividends, and the rulers of the empire spared no effort to expand while recovering from the scars inflicted by the war. Soon, the territory of the Thumiro Empire expanded to cover two-thirds of the Brilliant Continent. The rulers of the empire have a more ambitious ideal, and they have even formulated a grand plan to unify the glorious continent, fight to other continents, conquer the ancient Rocard Empire on the other side, force the Central Church to submit, and finally unify the three continents of Olopa.

At that time, except for the orc country in the south in the barren desert, the elven kingdom in the east hidden in the primeval dense forest, and the snowy federation north of the boundary mountain range for a long time, there was no benefit in occupying these places, so the Xiumiro Empire was not touched for the time being, and in the ** country of the Brilliant Continent, there was only a small kingdom called "Agulema".

Agulema, a small kingdom that was once a flash in the pan, is located on the Golden Gull Peninsula jutting out from the Olopalo Sea in what is now the Kingdom of West Lopa. The kingdom of Agulema was founded less than 200 years ago, but it was known for its fierce people and military bravery. Even in the most difficult period of the Demon War, when 90% of the country's territory was lost, the king still raised the whole army and fought the demons with guerrilla warfare for six years.

However, it was one of the Twelve Heroes of the Demon Slayer who made this small kingdom famous in history: the ancestor of the Assassins, Kuens Agulema, a prince of the kingdom of Agulema.

There are many heroic legends left behind from the era of the Demon War, but the friendship between Kuens Agulema and another of the twelve heroic dragon knights, Augustine Rato, is the most remarkable. After Auguston's death on the battlefield, with the help of Auguston's dragon partners, Kuens crossed the mountains and crossed the territory alone, all the way to follow the traces of the demon king who killed Auguston, and after 79 days of desperate pursuit, Kuens finally killed the enemy and avenged his friend, but he also paid the price of his own life. This allusion has been put on the stage of opera countless times in later generations, and has become an idol imitated by many hot-blooded young people.

I don't know if it is precisely because of this glory that the Shumiro Empire, which also produced a Twelve Heroes of the Demon Slayer - Lord Cayton Myronmay, the Knight of the Round Table, will have a taboo against Agulema, this is unknown. But what is certain is that the comparison between the huge Shumiro Empire and the weak Agulayma Kingdom is like an elephant and a mosquito, but the war between the two, the Shumiro Empire has been lame, and the army that claims to have millions of people has bitten on the steel plate, lost its troops, and still failed to obtain half an inch of the Agulayma Kingdom, and the dream of unifying the three continents of Olopa has been stuck in this throat.

The resistance of the kingdom of Agulema was able to continue tenaciously, and the backbone was a young king born after the war against demons.

In the year 409 BC, in the year 4507 of the original continental calendar, that is, the 10th year after the end of the Demon War, a cry of a baby fell to the palace of Agulema. The queen who was approaching menopause brought the king one of the youngest princes. It is said that the prince was born at midnight, when a golden light streaked across the sky of the palace, revealing the lurking forces of the Shumiro Empire that were lying in ambush around the palace, and the defenders wiped out the invading enemy and captured the imperial generals, completely bankrupting the empire's attempt to capture the king and force him to sign the terms of the annexation.

The king was very pleased with this, and he believed that his son had brought about the victory. Therefore, the king named the little boy "Marn", which means "light of hope" in the ancient Olopa language.

Sure enough, the little prince did not fail his father. On the day of the full moon, the maid who took care of the little prince unexpectedly discovered that Prince Marne had actually dismantled the mosquito net from the crib, picked up a small stick that he could not pick up at his age and used to support the mosquito net holder, and lay down on the crib and danced wildly. The king was astonished, and when he came to see the little prince's situation, he found that his son was not wielding the stick casually, but the king, who was also proficient in the use of various weapons, found that this was a very exquisite set of marksmanship, and when he danced from his son's hand, he seemed so professional and skillful, as if he had practiced it for decades.

The king was overjoyed, and hurriedly issued a reward order, and recruited famous teachers who were proficient in spearmanship throughout the country to serve as spear instructors for his children. However, it turned out that the king was completely superfluous. Because when the little prince was three years old, he had completely mastered the use of a whole set of marksmanship, and the movements he wielded were so smooth and exquisite that even the sharp-paid marksmanship instructor was amazed when he saw it, and after knowing that he was unable to teach it, he was ashamed and asked the king to resign.

At the age of five, the little prince was already able to defeat regular soldiers on his own with a small wooden gun.

At the age of seven, the little prince often disappeared suddenly at night, and while the palace was in chaos, he returned a few days later unharmed. Asked where he went, the little prince kept silent every time, but after each disappearance and return, the little prince's marksmanship improved greatly. Gradually, the king resigned himself to the matter, knowing that a famous teacher who did not want to reveal his identity was guiding his son.

When he was thirteen years old and ready to ride, the little prince shocked the nation by single-handedly picking down one of the king's best knights, who later willingly became the most loyal subordinate of Prince Marne, who could be his son.

Prince Marne is not only extremely gifted in spearmanship, but also very quick to learn other things, especially when it comes to arranging troops and governing the country, and he is studying it with a seriousness that does not match his age.

At the age of fifteen, the Thumiro Empire attacked again, the first time Prince Marn went to the battlefield, he single-handedly rushed into the enemy formation, and frightened an old general who was responsible for protecting his safety, but unexpectedly, Prince Mar came back safely, with only a slight abrasion on his body; the second time he went to the battlefield, the little prince directly picked the head of an officer of the enemy army back with a gun; when he went to the battlefield for the third time, in order to prevent the little prince from rushing to the front line, the old general handed over part of the army to the command of the little prince, but he did not expect the little prince to lead this small detachment and burn the emperor on the back road**, so that the battle ended earlier than the old general had planned.

After this battle, the whole country boiled.

After becoming famous in World War I, Prince Marne then experienced several large and small wars, his military strategy was as unfathomable as his personal bravery, and where the crimson spear in his hand pointed, the emperor was undefeated, and finally forced the arrogant empire back to the negotiating table.

Prince Marn's prestige became more and more famous, and he was loved by the common people, and countless noble ladies flocked to him, and secretly sent autumn waves and coquettishness, however, the arrogant prince did not seem to have the slightest interest in these women sent to the door; on the other hand, as his fame grew, several princes who preceded Marne in the order of succession to the throne were wary and suppressed at every turn against the youngest brother.

At a moment of fame and danger, Prince Marn suddenly made a surprising move: he decided to go to the galaxy continent on the other side of the sea alone to experience, and despite anyone's opposition, he set off quietly on a starry and moonless night, avoiding all the guards.

That's six years. No one knew where Prince Marne had gone, and no one had heard of him.

The old king's illness became more severe with age, and the struggle for succession within the court became more and more acute, and the country began to be in turmoil. The Thumiro Empire, which was looking forward to the delay, saw this opportunity, tore up the peace treaty, launched an army of millions of people, and launched a new invasion.

This time, Agulema was caught off guard by the infighting, and when the princes who had broken their heads for the crown prince's position woke up, it was too late. The emperor drove straight in, all the way to the royal capital.

Faced with the critical situation of the soldiers approaching the city, the old king, who had been bedridden for a long time, was dying, and several princes surrendered, some fled, and some planted themselves, and the soldiers and civilians lost the will to resist, and the fall of the kingdom of Agulema was imminent...... At this moment, Prince Marn, who had been missing for six years, descended from the sky with a golden light, just as he had been born on the day he was born. The return of Marne not only brought back more terrifying combat effectiveness, but also lifted the morale of the army and the people.

The army was assembled under Prince Marne's crimson spear. Although the commander of the emperor ** believed that his million-strong army was completely in control of the overall situation, he still could not change the outcome of the rout on the whole front. The crimson spear and the figure of Prince Marne seem to be integrated, and after nearly half a year of hard fighting, the land invaded by the emperor has been fully recovered.

When peace came again, Prince Marne, who was only 24 years old, was officially crowned king with his father's crown in front of all eyes.

King Mar ruled the kingdom of Agulema for a total of five years. During the first three years of his reign, Agulema rose rapidly in power, and then, with sufficient supplies and training of his army, King Marn led his army into the vast territory of the Shumiro Empire.

In the decisive Battle of the Selea Forest, King Marne personally led 5,000 of the most loyal and elite knights to break the combined siege of the empire's 200,000 troops, and instead annihilated more than 40,000 emperors**, and beheaded the commanders of the emperors, and even captured a prince who supervised the war with the army, the younger brother of the emperor. It was only after the mediation of the Central Church and the payment of a large indemnity by the Empire that Marn released the prince.

After this fiasco, the Thumiro Empire was not only unable to launch an invasion of the Agulayma Kingdom, but even in the places that were originally conquered by them, the foundation of the empire's rule was loosened, and the uprisings demanded ** in various places continued, and finally drove the empire's forces back to their original territory.

The Battle of the Forest of Serea caused a sensation around the world, with the young King of Marne becoming a shining star in the world, and the small nation of Agulema, which received a large amount of reparations, immediately soared to become the richest nation in Olopa.

With the age of King Marn Agulema at that time, and his astonishing strategy, no one doubted that he would not be able to achieve great success, and some even predicted that Agulaima would overthrow Shumiro and become the new overlord of the Brilliant Continent in the near future.

However, no matter how people speculated and predicted at the time, the fact that Marn was the last king of Agulaima could not be changed.

Both Marne himself and his country were in their heyday, and the sudden upheaval shattered all the good things that had been shattered.

Without warning, King Mar died suddenly, and on the same day, the Golden Dragons attacked the kingdom of Agulema.

This rich, mighty nation was reduced to ashes in the midst of dragon fire. Their cultural treasures, their armies, their royal palaces, were all destroyed. The surviving citizens fled to other countries by land or sea, but the people who had lost their kings, cultures, and lands did not have the strength to rally them to restore their country, and were eventually assimilated by the local people in exile. The kingdom of Agulema has completely disappeared into the long river of history.

Now, two thousand years have passed. The original place where the kingdom of Agulaima used to exist has long been covered by towering trees. There are still some traces of ruins and other evidence that the country once existed, hidden in the dense woods, but this inaccessible forest has now become a paradise for golden gulls, and the few humans who set foot on this land are only adventurers and cunning thieves who are not afraid of death.

Although the West Ofi Kingdom, which later ruled the Golden Gull Peninsula, tried to establish settlements and ports on this land on more than one occasion, they all ended in failure. As for the reason for the defeat, the royal family of Xilopfei has always been tight-lipped......
