Perfect silence dominated the underground tunnel's pitch-black interior.

In the beginning, there were no pathways in the Underground world.

Thousands of years of water erosion resulted to the formation of only erratic rock fissures and water channels.

The winding cave system, however, with its numerous chambers, both large and small, were connected by tunnels of all lengths, creating an astounding three-dimensional tunnel system that extended in all directions.

Thanks to the endless excavation efforts of numerous generations of the underground creatures.

At this moment, in one of the many chambers that can be found in this underground world, a dim candlelight leaked through the endless darkness.

Not far away, a black hooded figure was sitting in front of a worn-out wooden table. There was a palm size card that was lying down in front of him, which he has been staring for the last hour.

From the fragments of the memory of this body, he learned that his name is Angus, a 15 years old and a young apprentice in path of summoning magic.

In addition, this is a magically advanced world with varieties of magical creatures roaming around everywhere.

Ghost Millipedes, Blood Bats, Scavenger Rats, and Demon Rattans. If he's not careful enough, any of these horrifying demonic creatures are more than enough to kill him.

However, Angus is unconcerned about this.

He was still perplexed at this point as to how this unassuming card had allowed him to escape from that damned tower. The tower that imprisoned him for the last million of years.

You could be reading stolen content. Head to Royal Road for the genuine story.

But he is aware that he is not yet completely free.

He can feel it. In that tower, his original body was still imprisoned.

However, for some reason that is unclear, his consciousness managed to flee and has since gained ownership of this apprentice's body.

Angus picks up the card and takes one final, close look.

The card has a smooth, mirror-like surface and is colored black.

He can hardly make out his long white hair from it because of how reflective it is.

On it's back, was a single red eye that occasionally blinked and would follow wherever he looked. Giving him a shivering sensation crawling down one’s spine and through his heart.

On the other hand, the front card shows a demolished building that is about to collapse. The lowest portion of this infrastructure contains scattered rubble.

Although Angus is unsure, he senses a familiarity with this building , as if he has seen it before.

"XVI Tower" he murmured, as he read the only text written on the bottom part of this card.

He greeted, "Yoohoo! Are you there? Can you hear me?" but few minutes have passed and the card was still unresponsive.

"I want to thank you for liberating me. Are you maybe the person I accidentally killed? I'm sorry but I did not mean it. I was half asleep at that time and you're disturbing my sleep. If you are awakened from a deep slumber, you will also feel angry, right? Right?" He was adamant.

As if doing it was morally correct.

He pondered if it would be possible to take the eye that was still watching him and put it on his forehead.

It would be fantastic.

Angus grinned and started exploring his adobe. His memories indicate that he has lived in this cave ever since being taken into this underground world.

His home is small, and he has only amassed a small number of properties throughout the last three years that he has lived here.

The only notable properties that he found while searching is a completely ripped book, a broken staff, a rusty dagger and few gold coins.

He can't help but face palm on how miserable and poor he is.

However, his top priority for now is to thoroughly comprehend the world in which he now lives.

Does he still reside in the same universe where his real body was trapped? Who are the strongest people in the world today?

What transpired in the war after he was apprehended and detained?

There are many questions, but it's a good thing he knows where to look for the answers.

Gathering his priceless treasures, Angus quickly leaves his lair.
