Luna was teleported into some white room after the Big Bang, She looks around and saw nothing except white.
"What is going on?"
[Host, you have been teleported in your own dimension]
『Universe Customization Activated』
The whole room turns its white walls into black and a Hologram of Luna's Universe could be seen.
[Host can customize her own Galaxy, Star, and Planets]
Hearing the System's explanation, Luna stared at it intently. But something was bothering her and she remembered that she still didn't have a body which was weird.
"System, Can I have my own Body"
[If Host's wants a physical form. Then System can open the Character Customization Menu]
"Open it, please"
『Character Customization has been opened』
Luna saw a screen that appeared in front of her. She could see a girl on the screen that looks like her. She uses the paint and colored her hair to pure black, Luna also changes her eyes into Violet. The current height of her self was 170 cm, Her body proportions were balance and her current age was 16 years old.
After customizing her old self. A bright light engulfed Luna it surrounded her whole orb body then the light started to transform. The transformation was fast and Luna founds out that she closed her eyes.
She slowly opens her closed eyes and saw that she had a body. Luna felt nostalgic for no reason, She bends her finger and stretches her arms. She created a mirror and saw her new body, It was very good considering coming from her current age which was 16 years old. Her pitch-black hair and violet eyes, she was currently naked but she didn't care since there was no one inside the white room that was black other than her.
Luna created a black gothic dress. She looks around the room and activates the Hologram projector. A nebula of gasses appeared in the form of a hologram and with the combination of the darkroom, it was like looking at it from space, She stared at it and felt very peaceful looking at the sight.
"System how can I create?"
[Host, Create anything from your imagination]
"Okay"
Luna controls the hologram as she used the system to build her first star. She wanted to have only a one-star system since it was hard to manage millions of galaxy with its own billions of stars that contains its own planets. (I wanted for this to happen so that I can track what happens to the world instead of using time skip)
At first, she just created a star that had a diameter of 10 Milky ways which means it was very big. But it explodes into a supernova after it was created.
"System?"
[The star couldn't handle that much of mass]
"Then how can I create the star"
[System will just change the core performance of the star] When the system said that A star that was comparable to what Luna made appeared and surprisingly it didn't explode.
"System can you make this star with the lifespan of a Dwarf star"
[Host's wish is System's command]
The star was tweaked by the system and although the size of it was very massive, Its lifespan was comparable to the Dwarf star and its fuel doesn't burn that much.
"System make the gasses all around the star into solids"
When the system heard Luna, The gasses all around them turn into rocks. Some were bigger than the solar system which made Luna at dazed. The Rocks were rotating around the sun at a fast speed, She was about to ask the System.
[The time in this dimension is different from your universe, The time here 1 to 1 million which means the time of your universe is 1,000,000x faster than normal]
The rocks started crashing into each other using their own gravity and planets were born. She uses her hologram to find the green line or the Lifeline of the star system which was neither very cold nor very hot. In this line, Life could exist and Luna built her first planet.
The planet was 1,000,000,000 km in diameter. Luna plans to make this planet, the Main world of her universe. The whole planet was rocky and it didn't have blue or green it was just grey. Luna created another 10 planets of the same size as the sun.
She uses the planets and throws them towards her main world, When the planets hit the main world Explosions were seen. Many debris from the planets were thrown towards space, Seeing that 10 planets were not enough.
Luna makes another 100 planets the same size as the sun and throws it all around the Main world. The main world was heating up as moon size meteors hit it and it comes from the planets that Luna made.
Volcanoes were appearing all around the world as Lava or magma heats up the whole world. When Luna saw the hell world she made, She was actually proud of it.
Time passes by and millions of years have passed by on her universe. The Primordial World Primaris stopped burning as it cools down. She names this world as a Primordial class which means the biggest planets that exist from her universe.
The debris that was left by the 100 and 10 sun sized planets were floating in space as it made their own planets.
"System I'm done with the planet, I'll start in customizing it. First, put an underground world all around the planet, and to prevent it from collapsing would be a million rocky pillars that would be 12,000km in diameter. Place them all around my main world, The Underworld would be 1,000,000 km deep down from the surface. And the Underworld's ceiling would be 50,000km in height."
The system immediately built the Underworld but it was still dark.
"System make can you make mana"
[Host, System can make anything]
Hearing the System's confirmation, Luna talked about her planned.
"System I want mana to be separated into two types. The Order and Chaos, Each of these mana had their own advantages and disadvantages. Scatter these 2 types of mana all around my universe"
The System immediately created mana and it was fascinating since phenomena started appearing all around the world.
"Put Energy crystals all around the Underworld so that there would be light"
Energy crystal the size of mountains started appearing from the ceiling and the floor of the underworld.
"It's time for the Surface"
The hologram immediately transferred to the surfaced.
"Make 60% of the surface underwater."
Water started appearing around the planet as it covered 60% of its landmass. The one landmass was separated into millions of earth-sized continents.
'It's time to make plants' But before she could do that she asked the system.
"System what is the height of the atmosphere and the deepest part of the Ocean"
[The Current height of the atmosphere is about 100,000 km in height while the deepest part of the Ocean is 50,000 km below surface level]
"Wow that's tall and the ocean is very deep can even light exist down there?"
[Light can exist in the form of Energy Crystal]
"System, make a flying island"
The Flying islands appeared all around the world and most of them had the sizes of the continents from the earth. The System started forming more Mountains with a height of 1,000km while hills that can make Mount Everest look like a kid.
"I'm proud of my World," Rose said while holding her chin with a smile as she looks at her world.
The World was very big and had millions of earth-sized continents that had more surface area than earth. The Underworld was very good due to its pillars and energy crystals while the Flying Islands was Epic.
It had many planets orbiting around it and It was a very beautiful World.
"System put all the plants that exist on earth into my planet and make them adapt from mana. I also want plants like the World tree and Plants for the Underworld"
[Searching Database...]
[567,456,789,123 plants could be found. Would you like to put it all?]
"Put all of them"
The billions of new plants were scattered all around The World, The Oceans, and The Underworld. The Main world was having its greeny spots and with the 1,000,000x acceleration, it started to spread all around the world leaving nothing behind.
"System can you make the time 1 to 1"
[Understood Host]
The time slowed down and the planet was slowly spinning, unlike the last. The Main world days were different since 500 hours were one day while one year was 500 days. This made the year messed up but still okay.
Luna teleported into some random island as she was on the beach looking at the sea. Winds could be heard as Water was splashing. She looks at the sunset and saw the world she made,
Her tears were slowly leaving her eyes as she looks at the sunset for the first time in an [Data Redacted] of years.
"My time has come.."
