Thousands of years had passed on Earth, and everything was running as normal. Then, suddenly, the fabric of space began to tear open at various places, forming structures that looked like black holes. Humans believed these were gateways for teleportation, so they called them "Teleporters."
Whoever entered one of these teleporters was transported to a completely different world — a place where bushes, trees, and plants weren't green but glowed in strange, vibrant colors. Towering mountains rose into the skies, cascading waterfalls shimmered down their cliffs, and the valleys were so breathtakingly beautiful that it felt like stepping into heaven itself.
But that beauty was deceiving. Many of the plants were deadly — a single touch could kill a human instantly. The water and food there were toxic, and instead of ordinary animals, enormous monsters roamed the land. Some were as tall as mountains, others half-human and half-beast, terrifying to behold — so terrifying that one glimpse could chill the soul. Their power was unimaginable; they could kill humans with a single breath.
Human technology wasn't advanced enough to fight them. Most of those who entered the teleporters never returned. Some were killed by monsters, others by the deadly flora, and those who survived often died from hunger or poisoning, never able to find their way back to Earth.
But a few who did return told shocking stories. They said, "The moment we arrived in that world, our bodies began to change. A voice echoed in our minds — 'Welcome to Sinonius Planet'. Then, a virtual human model appeared on our hands. We could control it with our thoughts — summon it in our minds or project it over our skin. At first, we had no idea what it meant."
"Suddenly, a monster attacked us — its head like that of a bull, its body human-like. We fought it for five long hours. Four of our companions died. Finally, one of us managed to kill the creature. Then, a glowing virtual model emerged from the monster's mind and appeared on his hand. It said:
'You have slain a Mortal Realm Monster. You have gained 7% Mortal Energy.'
Instantly, he felt power surging through him — stronger than before. The model then displayed his status:
Power: Mortal Realm
Life: 200 years
Mortal Realm Energy: 7%
Next Realm Requirement: 100% Mortal Realm Energy."
This phenomenon spread across Earth like wildfire. As soon as the government learned about it, they established training centers wherever teleporters had appeared — known as "Academies."
To travel to the Sinonius Planet, humans now had to train for two years in these academies, learning survival skills, self-protection, and ancient Martial Arts — the only way to defeat those creatures. High-tech weapons had no effect on them. The older and purer the martial art, the more powerful it became there.
Martial arts were no longer just a fighting style — they evolved as humans defeated monsters, granting them supernatural powers.
Four hundred years passed on Earth. Humans had become far more powerful than ever before.
Then, one day, at the Monster Academy — the largest and most prestigious academy in the world, where only the rich could study — shocking news spread.
Four humans suddenly appeared from the teleporter… and what they revealed made every human in that academy tremble with fear...
