Review Detail of They_call_me_God in I’m Cultivating Immortality While Everyone Else Practices Martial Arts

really enjoyed this until around chapter 250, tried to read more but for some reason there are a lot of unexplained and sudden changes made to the characters and world. mc changes his personality, characters revive themselves and his friends forget him and change personality . I would really like to continue this but after a certain point, it just doesn't feel like the same novel I enjoyed.
