How far can the desire to live and the lust for power of an unsatisfied soul go?

Jean is a hypermarket clerk. A fan of RPG and survival video games. A lover of fantasy and isekai in general. A young woman who doesn't remember much of her life after a setback upon arriving in the new world. Not even the pact she made with an unknown deity.

She will have to find a way out of the depths of a sinister mountain full of enigmas. Why has she appeared there, where a powerful corruption has taken root?

English isn't my native language, so go easy on me. Any feedback is more than welcome, of course.

What to expect:◦ Single MC who gains allies over the course of the story.◦ Long series with slow start and progression.◦ Post-apocalyptic fantasy medieval world.◦ Publication rate: As long as my writing process doesn't improve, four per month.
