Be the Protagonist in the World of Cultivating Immortals, Begging Readers to Add Settings

[Cultivation of Immortality + System + Decisive Killing + Multi-World Travel]… Whose family was wiped out just after they traveled through time... Li Wushu didn't expect that one day he would travel to a certain author's world of immortality novels and become the protagonist. He didn't even expect that he would not be able to cultivate immortality after traveling to the leisure world! You can only choose settings based on readers' comments! He never thought that anyone would just travel through the past and be massacred... And there would be many other time-travelers in the world after traveling... And all this story originated from a post I came across.
