Does Anyone Recommend Some Metaphysics or Immortality Novels? (Female Channel)

I want the female protagonist to be very, very strong. She can be very talented and strong in the later stages, or she can be extremely strong from the beginning but is very weak. It doesn't matter if there is a male protagonist or not, but don't overwhelm the female protagonist. I want the female protagonist to be invincible! ! ! It can be rebirth, soul travel, time travel, etc. Thank you
