Superstar From Age 0 - Chapter 415:

Being abandoned by his very own blood, the world stripped him of everything, his glory, his weapon, his beloved and even his name was taken away. He tried to reclaim what were rightfully his but the people already treated him as an outcast.With nothing left to do, he strode towards the place of no return and as he reached the deepest part by accident, he found a sealed casket with an unusual question engraved on its lid.'If the world's destruction would be put in the palm of your hand, how would it end?'Thousands of choices, hundreds of possibilities, and tens of answers, yet just one of these was certain.“I'll carve it with my enemies' blood,” he uttered underneath the moonless sky.On his hand was a blade made of glass, dripping with a crimson, sticky substance. In an era where war was an everyday occurrence and death was nothing but a mere consequence of being weak, his journey towards the labyrinth of revenge had begun.- - - - -Read at least six chapters and please be prepared to crave the rest. Enjoy Reading!

This isn’t the struggle of an empire, nor the tempest of another world, and definitely not a cultivation story. This is actually a super serious (not really), super hard sci-fi novel about saving the world. Take what I’m saying seriously.(Don’t)

Okay, it’s really just a bunch of slippery leaders and their deceptive emperor having a fun time saving the world everyday.

An unmotivated otaku is transformed into the Emperor of an ancient intergalactic magic sci-fi empire, and with the aura of a stay-at-home dad, he is similar to an uncle who adopts an army of lolis. This is the hilarious story of an otaku and his freeloading army that appeared out of nowhere. Once again, this is a super serious story. This is a super-ultra-serious sci-fi story.

Have fun 😉
