The End of the World: My Energy to Wake up Is 100 Million Points Strong

I am an old monster who sleeps fifteen hours a day. I have been wandering around in this human-eating apocalypse for more than a hundred years. As a long-lived superstar in the third era and a living fossil in the big world, I have passed the age of competitiveness and have become indifferent to fame and wealth, and compassionate. However, I seem to have met some blind guys recently who always disturb my sleep... In this case, just shoot them all into the ground and let the world be quiet.
