On one fateful day, when everyone went on with their mundane lives, the Earth was found in the Dark Forest known as the universe, resulting in unknown extraterrestrial beings preying on the weak — the humanity. Grey, an intern, was then killed due to an alien invasion, only to find himself reincarnated in the mysterious world known as Magica. But wait... "I've become an alien?!" Integrated with a mysterious entity known as the Extraterrestrial System, follow Grey's journey as he begins to seek the mysteries of the world while gradually, slowly, but surely building his Alien Empire despite being surrounded by powerful existences such as Heroes, Demon Lords, and other magically powerful beings.
The Cosmion Tree, which consists of one hundred miniature worlds, was one of the thirty-three (33) subsystems.
The message of the Fairy Queen was heard and it inexplicably resonated with Grey's heart and mind.
Although the true nature of the subsystems and the purpose of their existence were perceived to be murky waters, Grey sensed that he had taken a significant step to the endless ladder towards the unknown, where the answers were hidden and yet to be uncovered.
"The Cosmion Tree itself?" What the Fairy Queen conveyed was loud and clear, but Grey wanted to reaffirm it.
"Indeed. Tell me more about what the Stone Dragon had told you. Even if she couldn't ascertain the truths from lies and the lies from truths, you couldn't rule out the possibility that some words that came out of her mouth were genuine."
