The sky was covered by red dark clouds, cyclones formed all over the place, thunder and lightning was raining down on the ground.
"OURANOS! TODAY YOU WILL DIE AT MY, TYPHON, HANDS AND I WILL FREE MY BRETHREN TO THIS PRISON!"
A loud voice envelop the whole city of Orario, and the tower of babel that seals the dungeon collapse. All of the civilian were shock and horrified of the sudden event.
A bit later large tremor follow up, monsters emerged from the dungeon and kill everything on its path. Adventurers protect tried to fought back in order to protect their family.
The civilians evacuate the city while the adventurer stays.
From then on lots of adventurer fought and fell but the wave of monster coming out of the dungeon is unending.
Orario the city of adventure becomes hell.
The people of Orario thought that the situation is awful enough but the author said that the worst in not yet to come.
A pillar of fire shot up to the sky from the dungeon, even the monsters who was coming out from there was incinerate to ash. A massive black dragon with a horn on its snout and has two sets of wings. Its overall length measures around 50 meters emerge from the dungeon.
All adventurers were paralyze and felt fear from its gaze but a woman dash towards the dragon and jump from roof to roof to reach it.
"Aiz!"
Aiz Wallenstein or also known as the "Sword Princess" currently one of the strongest in Orario. She's a member of the Loki Familia, which managed to battle they way to the 59th floor.
The people who saw her at this moment thought that she have become crazy but a certain boy followed Aiz and face the dragon. A boy who wanted to become a hero, Bell Cranel.
Aiz bravely face the black dragon. She enchant herself with her own magic and tried to stab the heart of the dragon with her sword but the dragon's tail swipe at her with an unbelievable speed shooting her back to the ground.
"Aiz-san! Firebolt!"
Bell fired a firebolt at the black dragon and quick went to where Aiz fall.
The fireball didn't hit the dragon's body and was stopped by a spherical barrier that enveloped the whole dragon's body. The dragon hover still in the air and look at them mockingly, then it opened its jaw while facing the sky.
The adventurer was confuse at what the dragon's doing when a high elf from Loki Familia suddenly shout.
"Stop it from what its doing."
The other member of Loki Familia look at the Elf who probably knows what's happening.
"What it is doing Riveria?"
"It's currently gathering a mana around and condense it above its head, if that concentrated magic fall to the ground the whole Orario will be wipe out from the map."
Upon knowing what the dragon was doing the adventurer started to fire arrows and magic towards the dragon.
Some of them even throw their swords and axe towards the dragon but it didn't reach the dragon and still stopped by the barrier.
The dragon didn't bother to look at what the adventurer doing continue condencing a the mana. Quickly a blazing miniature sun manifested above the dragon.
"Attack at a single point, we might penetrate the barrier if we all attack at a single point"
The adventurer became desperate and attack with all they might as they saw a blazing mini sun above the dragon that it condense from gathering a mana. They did all they can but all their attacks are in vain.
Soon the dragon stopped gathering and controlled the blazing sun towards the ground.
The adventurers panic and all run away, but it was already too late. They all can feel the heat that coming from the miniature sun as it is falling to the ground.
All mage adventurer cast a large barrier to protect their Famlia. while others look at the approaching sun and fell on their knees.
"God/Goddess why did you abandoned us."
This is the thought of all the adventurer in Orario city as they found that all gods and goddesses suddenly disappeared before all of it happen.
While waiting for their death, suddenly a flash of light shot from the sky to the ground piercing the sun and create a crater and dust, then sun was split in to half. They all surprise to see the sun suddenly split in to half like it was cut, still their shock does not end.
The sun that was split into half turned into ice before exploding to snow dust.
While shock all of them look to the crater to see what cause such absurd thing and they all saw a human figure inside the dust.
The dust quickly disperse and they saw a person in white cloak looking at a certain direction, they can't see the person's face because of the hood that was covering the persons face.
They look all look to where that person is looking and their jaw dropped.
They saw the dragon 50 meter tall already on the ground without a head, and its head was being dragged by another person wearing black cloak towards them.
The person with black cloak took off his hood and looked at the onlookers then ask a question.
"Is this the strongest monster here in Orario?"
