Linn traveled through time and became a slime.
Other people's systems: Ding! Congratulations to the host for obtaining god-level skills!
My home system: Ding! Please shout to the goblin in front of you - "I am the demon king who has returned from hell!"
Lynn: "... Can I change my skills?"
System: "No, the volume is not loud enough and the energy is not enough. You will die on the spot."
So, in this chilling world of swords and magic:
All mankind is laughing at that slime who only knows how to dance and recite shameful lines.
Until that day, the door of the abyss opened and the devil came to the world.
The slime stood in front of everyone and let out its final roar:
"Feel the despair coming from the stars! Starburst abandons healing!"
At that moment, the demon cried and humans were dumbfounded.
——It turns out that he is not going crazy, he is saving the world.
