Fantasy: Sign in Every Day to Achieve a Hundred Years of Cultivation

This is a world where demons and ghosts run rampant. No monks and no strong men can stop them. People in this world can only become blood food in the mouths of demons. Han Qing traveled to this world and had a sign-in system. Day one. "Ding! The system automatically signs in, congratulations to the host for achieving a hundred years of cultivation!" The next day. "Ding! The system automatically signs in, congratulations to the host for achieving a hundred years of cultivation!" … The hundredth day. "Ding! The system automatically signs in, congratulations to the host for achieving a hundred years of cultivation!" … The thousandth day. "Ding! The system automatically signs in, congratulations to the host for achieving a hundred years of cultivation!" … If you cultivate for hundreds of years every day, you won't be able to become an immortal. There were originally no monks or immortals in this world, but because Han Qing came, there were monks and immortals. With monks and immortals, demons and monsters no longer run rampant.
