(Immortal Cultivation + Traits + Gender-Swapping Transformation + Marries Once + Demons + Attains Sainthood)
The protagonist is a programmer who transmigrates to an ancient high-martial world.
This world is full of dangers, with demons, martial artists, and immortals.
How can they keep their head down and develop safely?
Fortunately, the family they transmigrate into is well-off, a prominent martial family with a vast fortune. The protagonist can start ahead of everyone else.
But how can they be as cautious as possible? Could there be a way...
While the chosen one of this world is still struggling along at the bottom, marry him directly, latch onto his coattails, and start lying flat from then on. Hahaha!
Don't worry. The protagonist has the Book of a Hundred Mortal Lives, which lets them simulate reincarnation a hundred times. They don't actually get married.
