Twenty years ago, deep in a hidden underground cavern in the holy capital of Heratim.

The underground corridor seems empty and deep, and there are only a few copper lamps gently swaying in the huge space, exuding a trance of firelight, which can only vaguely illuminate the ancient stone walls on both sides of the corridor, which are carved with simple and fine patterns, which look like some kind of ancient cuneiform writing, the remains left in the erosion of the long years, densely climbing upward, and finally melting into the topless darkness.

There was a damp and salty smell in the air, and occasionally a cold wind blew from the end of the long cloister with a terrible chill, and beneath the feet was a rough primeval stone surface filled with a layer of cold moisture, and in some corners of the walls could even be seen shaggy moss, reflecting a wet halo in the dim firelight.

The young man leaned silently against the stone wall, his slender and well-proportioned figure cast a slender figure in the hazy firelight, the body wrapped in leather armor, the faintly bulging muscle lines looked full and powerful, exuding a faint but irresistible hormonal atmosphere, under the thick eyebrows that flew obliquely into the temples, a pair of clear and bright pupils stared quietly at the stone wall far away from each other, and there was an indescribable vigilance hidden in the seemingly casual and scattered gaze, like a cheetah roaming in the depths of the jungle, whether it was the surrounding grass or trees, it was the highest alertness, and his whole jade-like carved face also has a cheetah's deep and indifferent expression, and his handsome face has a frost-like aura, just looking at it from a distance, it seems to be able to make countless girls confused, but a hideous scar wantonly runs through the stunning left side of the face, as if the angel's pure face shows a devilish evil smile......

In the silence of the somewhat oppressive space, a light footstep suddenly came from the darkness at the end of the corridor, and the short sound echoed faintly between the stone walls, like the ripples of dragonflies spreading out of water, but for the young man, this slight almost ignored sound still could not escape his probing nerves, and the two black jewel-like pupils in his long narrow eyes turned in the direction from which the sound came from, and the flickering fire and the deep darkness appeared in his eyes at the same time.

As the sound of footsteps approached, a heavy pressure gradually condensed in the cold and damp air, as if the invisible air was freezing at a terrible speed, and even breathing began to become a little difficult......

However, this feeling only lasted for a short moment, and before the man could recover from the heavy pressure just now, the initial silence returned to the dark and damp corridor, and a ghostly figure emerged from the darkness with a faint outline, standing quietly not far from the young man's gaze, as if a swaying shadow standing upright on the ground, the pure black robe completely enveloped the person, and only a blurred jaw and a few strands of spilled silver hair could be seen in the loose and low hanging hood, and then in the next casual moment, the shadow dissipated like mist, When he condensed again, he was already less than five steps away from the man, even though the man was already on guard, but he was still a little caught off guard, and his naturally falling hand involuntarily stretched out to the long knife leaning against the stone wall nearby.

"It's me!" the figure in the black robe tilted his head slightly to face the young man, and his hoarse and dry voice sounded like that of a dying old man, "Hermes, you are still so alert......"

"Military ...... Legionnaire!" The young man, apparently hearing the owner of the voice, immediately bowed slightly and said respectfully.

"You've been waiting for a long time, haven't you?" the black-robed man asked faintly.

"No, the subordinates have only just arrived for a while......"

"You must be surprised......" The black-robed man seemed to see the desire in the young man's eyes, and then asked, "The person who quietly left a war letter to ask you to come here is actually me?"

"I ....."

"You think it's Mars, I don't want to lose so I want to challenge you again, right? Your battle of fate is over, and although he lost the duel, he also left an indelible scar on your face, which can be regarded as the price of your ascension...... Also, don't call me Legion Commander anymore......" The hood floated in the faint air current, and faintly a flickering point of light could be seen in the hood, "The current [Slayer] Legion Commander is you, Hermes Achilles! You can call me as you used to ...... Teacher!"

"Yes......" The young man named Hermes paused and replied in an aggravated tone, "Teacher!"

"Hmm!" the black-robed man nodded, striding towards the front of the cloister, "So, new Legionnaire, come with me, it's time for you to learn everything about the Slayer......"

“...... Yes!" Hermes hesitated for a moment, then picked up the two long knives leaning against the wall, followed the steps of the black-robed man, and disappeared into the darkness at the end of the cloister.

At first, at intervals, there would be a glimmer of copper oil lamps on the towering stone walls on both sides, but as the two of them went deeper, the distance gradually became longer and longer, and finally there was no light left in the silent corridor, and the cold and damp darkness rushed towards them, with a certain distorted weirdness......

"Teacher......" Hermes relied on his superior perceptual talent, firmly following behind the black-robed man, for the old man who had followed him for many years, he naturally trusted 100%, but the darkness that seemed to be out of sight, the strange feeling that came to his face and the long silence finally made the uneasiness in his heart gradually swell, he tried to break this suffocating silence, "Where are we going......

"Where are you going?" The black-robed man's low sigh came from the darkness ahead, as if he was in deep thought, and it took a long time for him to let out a hoarse and dry voice again, "The [Slayer] is known as the Grim Reaper, and the leader of each generation of the [Slayer] Legion is the strongest Reaper, and the leader of the Reaper, and the place we are going to is of course the tomb, the grave where the [Slayer] secret tomb is buried......"

"The grave where the secret of the [Slayer] is buried?" Hermes muttered.
