The Start.

Two centuries ago, a seismic event disrupted the world. It wasn't your typical technological shift or volcanic eruption. Instead, mysterious beings known as 'Monsters' abruptly appeared across the globe, pushing humanity to the brink of extinction.

At the center of this phenomenon was a mystical entity known as 'The Tower,' a land shrouded in mystery and granting these Monsters unparalleled power and authority. This place, dubbed the 'Abyssal Watchtower,' stood colossal with an astounding 100 floors, under the rule of enigmatic Gods and Demons.

As the tower emerged, a strange sound echoed worldwide, tempting everyone with its tantalizing message: "CLIMB THE TOWER. EVERYTHING YOU COULD WISH FOR WILL BE INSIDE. POWER? WEALTH? HONOR? IMMORTALITY? EVERYTHING IS POSSIBLE. CLIMB THE TOWER, AND WE WILL SATISFY ALL YOUR DESIRES. FIGHT THROUGH THE CHALLENGES WE HAVE FOR YOU!"

After hearing the announcement, the world erupted into chaos once again, as everyone wanted to climb the tower and gain strength. Governments worldwide attempted to restrain them, fearing a loss of control, but their efforts were in vain as the forces dispatched to halt challengers were obliterated.

Thus, the Gods and Demons proclaimed punishment for those who dared impede others from taking on the tower's challenges.

After that event, the world was in an uproar once again as people rushed to enter the tower, seeking refuge on its ground floor. As their world teetered on the brink of collapse, becoming uninhabitable, little did they know that the tower's interior was a vast, entirely new world, a hundred times larger than what they were used to. Once inside the ground floor, there was no way back.

The Abyssal Watchtower was a nexus connecting all living worlds, attracting not only humans but every race eager to challenge its heights. All of them converged on the ground floor and commenced their ascent at the age of 18, the day of their awakening.

Two hundred years later, in the year 2236.

Abyssal Watchtower, Ground Floor. (Human territory)

A female instructor, a member of the Awakening Association, dressed in professional attire, bore a serious expression, declaring, "Today marks the most pivotal moment of your lives. Embrace this opportunity as you step through the portal in front of you, arriving at the tutorial floor. There, you will unveil your innate talent, and after completing it, you all will reach the first floor, shaping your destinies and ultimately humanity's future!"

Before her stood a group of people, engaged in animated discussions while peering at the portal before them. Among them stood Ren, a slender and striking young man with pale white skin, dark brown hair, and entrancing deep ocean blue eyes. He sighed as he thought, "Today, I'll awaken my innate ability and begin my climb up the tower. My life has been a series of tragedies."

Thinking back on his troubled past, he continued, "Born into a family of scoundrels, my dad was addicted to drugs and gambling, abusive and worthless, never even attempting to climb the tutorial floor. My mom wasn't any better; her talent was useless too, and she earned money for herself by involving herself with multiple men. Thankfully, she neglected me, sparing me from further troubles. Then, on my 17th birthday, an unexpected twist occurred—both my scummy parents died in an accident. Strangely, I felt no sadness but rather relief that I wouldn't have to see their faces again. I started living in the cramped room they left behind, scraping by with a job at a coffee shop. Though the money hardly covered three meals a day, it was better than a single meal or no meal at all that I had before due to my father's habits and my mother's absence."

Suddenly, a loud sound from the portal interrupted his thoughts.

The female instructor's voice boomed, "ALRIGHT, THE PORTALS ARE OPEN!!! EVERYONE, STAY FOCUSED!!!"

"NOW!"

With excitement filling the air, all of them hurriedly rushed towards the portal, eager to begin their journey. Among them, Ren's weaker physique caused him to lag behind, but he persisted and made it through just in time before the portal sealed shut behind him.
