Female Queen: I Just Want to Cultivate Immortality Well

Sunan didn't expect that he would travel through time. It was just a matter of time travel, but the system arrived thirteen years late. The system said that it was because he had never encountered any danger to his life that the system was not activated. And Sunan said, is it a mistake to be protected too well by your mother? I thought that the journey to another world would pass by in an ordinary way, but unexpectedly, the emergence of the system caused the entire world of immortality to jump up and down... The early part of the protagonist's time in the secular world (the first 30 chapters or so) may have nothing to do with cultivating immortals, but more of a martial arts style - for the sake of foreshadowing, but when he gets to the world of cultivating immortals, most of the plot will involve cultivating immortals.
