I Kill Bemonstein Instantly at the Beginning, Then I Leave?

Traveling across thousands of years, looking at the strange blue star, and a familiar toy in my hand - the Evolutionary Truster Mulinsen said that he just wanted to go home and did not want to be the next generation strangled by the light tie. It's not an invincible novel. It's a bit sadistic at first, but then it will be normal to fight monsters and level up. There will be no female protagonist for the time being, mainly because it's too hard.
