The Emperor's Galgame Life

My name is Yuan. He is an immortal cultivator who has lived for five thousand years and secretly brought mankind from primitive times to interstellar civilization. My life ideal is simple: retire. Ruined. Play games. Until one day, I picked up a girl with green hair in the alley. She couldn't cook and cooked the takeaway into a biological weapon. She said she would cook for me for the rest of her life. She said her name was Nurgle. Then the second, the third, the fourth. They call me "Yuan", they call me "good guy", and they call me "the man who makes my noodles". They said that I should lead mankind and open a new era. Should I listen to them?
