Prologue

‘The day the door to the abyss opens, the age of men will come to an end.’

A part of the prophecy that has been passed down from ancient times.

But few truly believed in it.  After all, for thousands of years, mankind has never been on the brink of extinction.

However, the prophecy was real.

One night, when the moon was particularly red, the abyss’s door opened, and the monsters poured out.

Lord of the Undead, Wailing Eye, Frost Dragon, Wraith Knights, Giant King, Ruler of the Abyss, and more. 

Monsters that only existed in legends swept through the world and the glory and civilization built by mankind collapsed in vain. 

However, mankind did not give up. 

In order to survive, it desperately faced the monsters. And it was around this time that people called heroes or warriors appeared. 

Seven brave warriors passed the ordeal.

Great Warrior ‘Ulan’ was one of them. 

The Barbarian Warchief, Ulan Bator. 

The possessor of monstrous strength comparable to that of a giant, and the strongest power in charge of the hero’s party’s vanguard.

As if to demonstrate this, Ulan advanced forth, boasting of his formidable strength. As if there would be no defeats on his path.

But in the cave of giants. 

His advance stopped. 

“Huuk! Huuk!”

Crimson blood flowed down his chin while dozens of arrows penetrated his body. 

The giants’ arrows included. By human standards, they resembled a spear.

That’s not all.

His abdomen was punctured, and his intestines were rotten. His face was charred as if it had been poisoned.

It wouldn’t be strange if he died right away.

“Huuk! Huuuu!

While exhaling rapidly, Ulan recalled his past memories. 

One of the Rulers of the Abyss. 

Immediately after falling into the giant king’s trap.

Three of his colleagues were gravely wounded.

To make matters worse, the deadly poison poisoned even the Saint, the Hero party’s only healer.

The imminent crisis of annihilation.

But they must not die just yet.

The warriors were mankind’s last hope.

So Ulan volunteered to stay here. 

To give his comrades time to retreat, and to reduce the number of enemies by one more.

And the mission was a success.

The surrounding scenery was proof. 

Corpse, Corpse, Corpse! 

The corpses of giants piled up a mountain.

The blood that flowed from the mountain formed a river, and beyond that, a monster many times larger than the other giants could be seen dying.

King of the Giants, Largtan. 

The King who fought Ulan to the end. 

He too was about to die soon. 

「It was a great fight」

He said, in a voice of admiration.

「Warrior. Your name, I ask.」

There were many names that called him. 

The Great Warrior of the Meadow. 

Giant Slayer. 

The Red-Eyed Barbarian. 

The Great Warchief and so on. 

But all feats and glory were wasted in the face of death. So he calmly revealed his real name. 

“······Ulan.” 

After a short answer.

He let out a muffled voice. 

「Ulan, Ulan. I will remember.」

After muttering Ulan’s name over and over again. 

Largtan smiled contentedly. 

「Let’s meet again in the abyss and fight, Ulan. At the end of the abyss, I wait for you······」

At the end of the voice that gradually faded away, his body turned to ashes. It was an unusual end that only the monsters of the abyss faced. 

After the death of the Largtan, the King of Giants.

Ulan felt it too. 

That there was not much left in his life.

“Huuuu!”  

A blurred vision.

A faint breath dispersing as if it were breaking. 

Then, the records of life he had experienced for decades passed through his mind like a flash.

Memories of being born as a warrior in the meadow, becoming a Hero by challenging a legend, holding the most beautiful woman of the clan in his arms, and fighting for mankind. 

In this flood of memories. 

There were also many moments of regret and lingering attachment. 

That of not being able to reach the level of superman.

For failing to prevent his brother’s death.

Not being able to take responsibility for the clan until the end, etc. 

There were various regrets, but the biggest regret among them was meeting his end here. 

‘······· strength was not enough.’ 

If only I was more powerful than I am now.

If only my body was a little more strong.

If there had been an ax that was stronger than the ax that broke during the fight with Largtan, he might not have died like this.

The lingering regret continued biting its tail.

Ulan, who had come to the end of his regrets, realized it was Yearning. Yearning for a new life and an opportunity that will never come again.

‘If only I could live again…’ 

At that time, I will not regret it.

I will train my blessed body to the extreme, and challenge the realm beyond Great Warrior based on my experienced experience and knowledge.

I will obtain a much more powerful weapon than now. I will keep the promises I made with my colleagues to stop the Lords of the Abyss and return safely. 

Ulan made a silent promise.

Before long, his consciousness was about to disappear.

Suddenly a strange thing happened.-

Flash!

A white light suddenly emanated from the shabby necklace that was hanging around his neck. Ulan tilted his hazy eyes to look at it.

‘·······Mark of a Hero.’

About 30 years ago in the distant past.

When he was still a warrior of the meadow.

It was a mark obtained as a reward for challenging the ‘Trial of a Hero’, a legend passed down from generation to generation. But why was it suddenly shining?

When his mind was filled with doubts.

Paaaah!

The light enveloped the cave like an explosion of light.

And just in time.

Ulan’s consciousness also snapped.
